Tracheotomy

A tracheotomy is a surgical procedure that involves making an incision through the front of the neck into the trachea to create an opening, allowing for the insertion of a tube to facilitate breathing when the upper airway is obstructed or insufficient.^[1] This intervention, distinct from the resulting stoma known as a tracheostomy—though the terms are often used interchangeably—provides a direct route for air exchange, bypassing anatomical blockages such as tumors, swelling, or trauma.^[2] Performed either as an open surgical technique in an operating room or via a percutaneous dilatational method at the bedside, tracheotomy is indicated for emergent situations like acute upper airway obstruction from foreign bodies, anaphylaxis, or infections, as well as elective cases involving prolonged mechanical ventilation beyond 7-10 days, severe obstructive sleep apnea, or neuromuscular diseases impairing swallowing and secretion clearance.^[2] The procedure typically occurs between the second and third tracheal rings to minimize complications, under general anesthesia for open approaches or sedation with bronchoscopic guidance for percutaneous ones, and requires a multidisciplinary team including surgeons, anesthesiologists, and respiratory therapists.^[2] While it improves patient comfort, reduces sedation needs, and aids weaning from ventilators compared to endotracheal intubation, tracheotomy carries risks such as bleeding, infection, tube dislodgement, and late complications like tracheal stenosis.^[1][2] The history of tracheotomy traces back to ancient Egyptian records dating to around 3600 BC, evolving through classical descriptions by Hippocrates and Galen into a standardized modern practice refined in the 19th and 20th centuries with advancements in anesthesia and endoscopic techniques.^[2] Today, it remains a critical tool in intensive care units, with percutaneous methods gaining prevalence for their reduced invasiveness and lower complication rates in select patients.^[2]

Overview and Terminology

Etymology

The term "tracheotomy" originates from the Greek roots trācheia (τραχεῖα), meaning "rough" and referring to the textured rings of cartilage in the trachea, combined with tomḗ (τομή), meaning "a cutting" or "incision."^[3] This Modern Latin compound was first recorded in 1649, with the term entering common usage through the work of the German surgeon Lorenz Heister in 1718 to describe the surgical procedure of opening the trachea.^[3][4] Early adoption of the term was influenced by Latin medical nomenclature, where "trachea" itself was a Latinization of the Greek trācheia arteria (rough artery), a phrase used by anatomists like Galen in the 2nd century CE to denote the windpipe. French medical terminology also played a role in the evolution of related terms during the 19th century, particularly in the development of "tracheostomie," an early variant emphasizing the creation of an artificial opening.^[5] Historically, "tracheotomy" specifically denoted the incision into the trachea, while "tracheostomy"—emerging in French around 1887 and entering English usage in 1907—extended to include the formation of a stoma and often the placement of a tube, though the terms are sometimes used interchangeably today.^[6][5]

Definitions and Distinctions

A tracheotomy is a surgical procedure involving an incision through the skin and underlying structures of the neck into the trachea to establish an artificial airway, typically performed to bypass upper airway obstructions or facilitate long-term ventilation. This opening allows direct access to the trachea, enabling the insertion of a tube for breathing support, and is often temporary, with the site potentially closing after removal if not maintained. The term tracheotomy specifically refers to the act of making the incision, distinguishing it from tracheostomy, which denotes the resultant stoma (opening) and its ongoing management with an indwelling tube for prolonged airway support. While the terms are sometimes used interchangeably in clinical practice, this distinction emphasizes tracheotomy as the initial surgical intervention and tracheostomy as the functional outcome, particularly in contexts requiring extended care. Related terminology includes the tracheostoma, which describes the actual surgical aperture in the trachea itself, separate from the external incision. Usage of these terms can vary by medical specialty; for instance, otolaryngologists (ENT specialists) may emphasize the precise incision technique in tracheotomy, whereas critical care physicians often focus on tracheostomy as a component of ventilator weaning protocols. This etymological foundation, derived from Greek roots meaning "trachea cutting," underscores the procedure's historical focus on creating a tracheal opening.

Clinical Indications and Contraindications

Indications

Tracheotomy is primarily indicated for securing the airway in cases of upper airway obstruction, such as those resulting from tumors, trauma, or severe infections like angioedema or deep neck abscesses, where endotracheal intubation is not feasible or sustainable.^[2] Another core indication is the need for prolonged mechanical ventilation, generally anticipated to exceed 7–10 days in critically ill patients, as it facilitates weaning from ventilation, improves patient comfort, and reduces the risks associated with extended endotracheal intubation.^[7] However, recent reviews as of 2025 have reassessed the traditional "7-day rule," suggesting that optimal timing should be individualized based on patient factors rather than strict timelines.^[8] Additionally, tracheotomy serves to protect the lower airway from aspiration in patients with impaired neurological function, such as those with stroke, neuromuscular diseases like amyotrophic lateral sclerosis, or bulbar palsy, where swallowing reflexes are compromised.^[2] Specific patient populations benefit particularly from tracheotomy. In intensive care unit (ICU) settings, it is commonly performed for adults with acute respiratory failure who demonstrate difficulty weaning from mechanical ventilation, enabling better secretion management and pulmonary toilet.^[9] Patients with head and neck cancers often require tracheotomy to address airway compromise from tumor mass effect, post-radiation edema, or surgical reconstruction that anticipates obstruction.^[2] In pediatric cases, indications include congenital or acquired anomalies such as subglottic stenosis, bilateral vocal cord paralysis, or laryngomalacia, as well as prolonged ventilatory support in premature infants with conditions like bronchopulmonary dysplasia.^[10] Evidence-based protocols emphasize timely intervention to optimize outcomes. The Eastern Association for the Surgery of Trauma (EAST) 2009 guidelines (with an update in process as of 2025) recommend elective tracheotomy within 3–7 days of intubation for patients with severe closed head injuries or expected prolonged ventilation to shorten ICU stays and reduce pneumonia incidence.^[11] These approaches position tracheotomy as a preferred alternative to extended endotracheal intubation when long-term airway management is required.^[12]

Contraindications

Tracheotomy, whether performed via open surgical or percutaneous techniques, carries specific contraindications to mitigate risks of severe complications such as bleeding, infection, or airway compromise.^[2] Absolute contraindications are rare, particularly in life-threatening emergencies where no viable alternatives exist, but they generally include uncorrectable coagulopathy, high cervical spine instability, and inaccessible neck anatomy due to conditions like severe burns, post-radiation fibrosis, or massive soft tissue swelling that precludes safe procedural access.^[13][14] These factors prioritize patient safety by avoiding procedures that could exacerbate hemodynamic instability or lead to catastrophic vascular injury.^[2] Relative contraindications are more common and require careful clinical judgment, often favoring alternative airway management strategies such as endotracheal intubation for short-term needs.^[15] These include active neck infection or cellulitis, which increases the risk of spreading pathogens into deeper tissues; difficult anatomy due to obesity, prior neck surgery, or limited neck extension from trauma or rheumatoid arthritis; and anticipated short-duration ventilation requirements of less than 7 days, where the benefits of tracheotomy may not outweigh procedural risks.^[2][14] Additionally, severe respiratory failure with high ventilatory demands (e.g., FiO₂ >60% or PEEP >12 cm H₂O) or hemodynamic instability requiring multiple vasopressors represents relative barriers, as they may lead to desaturation or cardiovascular collapse during the procedure.^[15][14] Preoperative assessment is crucial to identify and address potential contraindications, balancing the need for secure airway access against procedural hazards. Coagulation studies, including platelet count (ideally >50,000/μL) and INR (<1.5-1.7), are essential to evaluate and correct bleeding risks, while imaging modalities such as ultrasound, CT, or MRI help delineate neck anatomy, vascular structures, and any distortions that could complicate access.^[2][14] In cases where relative contraindications are present, multidisciplinary consultation may allow for risk mitigation, such as stabilizing the patient or opting for delayed elective placement once acute issues resolve.^[13]

Alternatives

Endotracheal Intubation

Endotracheal intubation is a procedure in which a flexible endotracheal tube is inserted through the mouth (orotracheal) or nose (nasotracheal) into the trachea to secure the airway and deliver mechanical ventilation. The tube bypasses the upper airway, allowing direct access to the lungs for oxygenation and carbon dioxide removal in patients with compromised respiratory function, such as those experiencing hypoxia, hypercarbia, or inadequate respiratory drive. Typically performed using direct laryngoscopy, video laryngoscopy, or fiberoptic guidance, the process involves visualizing the glottis, advancing the tube past the vocal cords, and inflating a cuff to seal the trachea and prevent aspiration. This method is essential for maintaining airway patency during general anesthesia, emergency resuscitation, or short-term support in intensive care units (ICUs).^[16] As a non-surgical alternative to tracheotomy, endotracheal intubation offers several advantages for short-term airway management, particularly in acute settings. It enables rapid airway establishment—often within seconds during emergencies—without requiring surgical incisions, minimizing immediate procedural risks and allowing for immediate mechanical ventilation initiation. Suitable for durations of less than 1 to 2 weeks, it is commonly used in scenarios like perioperative care or initial ICU stabilization, where patient recovery is anticipated quickly; modern tubes with low-pressure cuffs further reduce early complications when managed properly, such as maintaining cuff pressure below 25 mm Hg to avoid mucosal ischemia. These attributes make it the preferred initial approach for reversible conditions, facilitating easier nursing care and extubation compared to more invasive options.^[16][11] However, prolonged endotracheal intubation carries significant limitations and risks, particularly beyond 7 to 14 days, prompting consideration of tracheotomy. Laryngeal injury, including vocal cord ulceration, granuloma formation, or arytenoid dislocation, arises from cuff pressure on delicate tissues and tube motion, with incidence rising twofold after extended durations. Sinusitis develops in up to 30% of nasotracheally intubated patients due to mucosal drying and bacterial colonization in the paranasal sinuses. Additionally, ventilator-associated pneumonia (VAP) is a major concern, occurring in 10-20% of mechanically ventilated patients, facilitated by biofilm on the tube serving as a reservoir for pathogens that bypass upper airway defenses. These complications contribute to increased morbidity, prolonged ICU stays, and higher mortality rates. Transition to tracheotomy is typically recommended for ICU patients expected to require ventilation longer than 7-10 days, based on factors like neurologic status, weaning failure, and overall prognosis, to alleviate upper airway trauma and enhance patient comfort.^{[17][18][11][19]}

Emergency Airway Procedures

Emergency airway procedures serve as critical interventions when conventional methods like endotracheal intubation fail, providing rapid access to the airway in life-threatening situations where tracheotomy cannot be immediately performed. These techniques are particularly vital in "cannot intubate, cannot oxygenate" (CICO) scenarios, where oxygenation must be restored within minutes to prevent hypoxic brain damage or death.^[20][21] Cricothyrotomy, also known as cricothyroidotomy, involves making an incision through the cricothyroid membrane to insert a tube directly into the trachea, offering a faster and simpler alternative to tracheotomy in emergencies. It is the preferred method for emergent surgical airway placement in adolescents and adults when endotracheal intubation is unsuccessful, often due to trauma, obstruction, or swelling.^[20] The procedure follows a structured "scalpel-bougie-tube" technique recommended by guidelines: first, identify and palpate the cricothyroid membrane using the "laryngeal handshake" method; make a horizontal stab incision through the membrane; insert a bougie to guide a 6.0 mm cuffed endotracheal tube into the trachea; inflate the cuff and confirm placement with capnography and bag-valve-mask ventilation.^[20][22] This approach achieves high success rates in simulations and real-world cases, with complications including bleeding (up to 50%) and subglottic stenosis if prolonged, though it serves as a temporary bridge to definitive airway management like tracheotomy.^[20][22] For scenarios where even scalpel cricothyrotomy is challenging, needle cricothyrotomy or transtracheal jet ventilation (TTJV) can provide interim oxygenation as bridges to tracheotomy. Needle cricothyrotomy entails inserting a large-bore catheter (e.g., 14-gauge) through the cricothyroid membrane and connecting it to a ventilation source, but it has lower success rates (around 37-57% in audits) due to risks of barotrauma and inadequate ventilation from the narrow lumen.^[22] TTJV, performed percutaneously with a specialized catheter, delivers high-pressure oxygen pulses directly into the trachea, enabling temporary ventilation during CPR or obstruction; it has restored oxygenation in hypoxic arrests, allowing subsequent definitive airways, though it carries risks of pneumothorax, subcutaneous emphysema, and cardiovascular collapse if not managed properly.^[23][22] These methods are not intended for prolonged use and require immediate progression to surgical options. The Difficult Airway Society (DAS) algorithms outline a stepwise escalation for emergency airway management, starting with up to three intubation attempts (Plan A), progressing to supraglottic airway devices (Plan B) and face-mask ventilation (Plan C), and mandating immediate front-of-neck access (Plan D) if CICO develops.^[21] Updated in 2025, the guidelines emphasize early cricothyroid membrane assessment, full neuromuscular blockade before eFONA, and a default vertical skin incision for scalpel techniques to streamline decision-making in crises, prioritizing first-attempt success over failure recovery.^[21][24] All practitioners must undergo regular simulation training to ensure proficiency, as delays in these procedures significantly increase mortality.^[22][21]

Equipment and Components

Tracheostomy Tubes

Tracheostomy tubes are specialized medical devices designed to maintain an open airway by bypassing the upper respiratory tract after a tracheotomy procedure. These tubes consist of a curved shaft that is inserted into the tracheal stoma, secured by a flange to the neck, and connected to ventilatory or humidification systems as needed. The primary goal is to ensure effective airflow while minimizing trauma to the tracheal mucosa.^[2] Key components of a tracheostomy tube include the outer cannula, which forms the main shaft and is inserted into the trachea; the inner cannula, a removable liner that allows for easy cleaning to prevent secretion buildup; the obturator, a temporary guide used during initial placement to direct the tube; and the cuff, an inflatable balloon on certain models that seals the trachea against the tube to prevent air leakage during mechanical ventilation. The outer cannula may also feature a 15 mm connector for attachment to respiratory equipment and a flange with ties or Velcro for stabilization. These elements collectively facilitate airway patency and ease of maintenance.^[25][26] Tracheostomy tubes are available in various types tailored to patient needs. Cuffed tubes, equipped with an inflatable cuff, are used primarily for patients requiring positive pressure ventilation to create a seal and reduce aspiration risk, though the cuff does not fully prevent aspiration. In contrast, cuffless tubes lack this feature, offering lower airway resistance and are preferred for patients weaning from ventilation or those with spontaneous breathing. Fenestrated tubes include openings along the shaft to allow airflow through the vocal cords, enabling speech and upper airway breathing when the inner cannula is removed or capped. Additionally, tubes can be single-lumen (without inner cannula) or double-lumen designs.^[2][25][26] Materials for tracheostomy tubes prioritize biocompatibility and durability. Most modern tubes are made from silicone, which is soft, flexible, and resistant to secretions, reducing mucosal irritation compared to earlier rigid options. Polyvinyl chloride (PVC) is another common plastic that softens at body temperature to conform to tracheal anatomy. Metal tubes, typically silver or stainless steel, are cuffless, reusable, and suited for long-term use in stable patients but are less common due to their rigidity. Selection of material considers factors like patient sensitivity and expected duration of use.^[25][26] Sizing of tracheostomy tubes is determined by the patient's age, anatomy, and tracheal dimensions, with measurements focusing on inner diameter (ID), outer diameter (OD), and length. For adults, common sizes range from 4.0 to 8.0 mm ID, corresponding to ODs of approximately 6.5 to 10.5 mm, with females often using smaller tubes (OD around 10 mm) and males larger ones (OD around 11 mm). Pediatric tubes are generally smaller, cuffless, and single-lumen, scaled to the child's tracheal diameter (typically 2/3 to 3/4 of the trachea to avoid pressure). Proper sizing minimizes resistance and complications like tracheal dilation.^[25][27] Selection criteria for tracheostomy tubes are guided by clinical indications and patient-specific factors. Cuffed tubes are chosen for ventilated patients to ensure airtight seals, while cuffless or fenestrated types support weaning, speech, and decannulation by promoting natural airflow. Tube length and curvature are adjusted for anatomical variations, such as obesity or tracheal stenosis, and materials like silicone are favored for prolonged use to enhance comfort. Duplicate tubes and one size smaller should be readily available at the bedside for emergencies. Overall, the choice balances airway security, ease of care, and functional goals like communication.^[2][25][26]

Associated Devices

Humidification systems are essential ancillary devices used with tracheostomy tubes to maintain airway moisture, compensating for the bypass of the upper respiratory tract's natural humidifying function. Heat-moisture exchangers (HMEs), often referred to as artificial noses, capture heat and moisture from exhaled air and recycle it during inspiration to prevent mucosal drying and reduce secretion viscosity. ^[28] These passive devices attach directly to the tracheostomy tube hub and are particularly beneficial for mobile patients transitioning from heated humidifiers, providing portable humidification without the need for external power sources. ^[29] HMEs are typically replaced every 24 hours or when soiled to avoid occlusion, and they support low-flow oxygen delivery in select models, though they offer less humidification than active heated systems and require monitoring for increased secretions or respiratory distress. ^[30] Securing devices play a critical role in stabilizing tracheostomy tubes to prevent accidental decannulation and minimize tube movement, which can lead to stoma trauma or airway compromise. Traditional twill ties, made of durable cotton fabric, are threaded through the tube's flange eyelets and tied around the neck with a double square knot, allowing space for one finger to ensure patient comfort while maintaining security. ^[31] Commercial holders, such as Velcro-based tracheostomy collars, offer an alternative with adjustable fasteners that attach to the tube flange, facilitating easier application and removal compared to ties, especially in patients with limited mobility. ^[32] These devices are changed when soiled or loose, and their use follows a two-person procedure to hold the tube in place during adjustment, reducing risks of displacement during daily care. ^[31] Monitoring tools enhance patient safety and communication in tracheostomy care by integrating with the tube for real-time assessment and functional support. Capnography adapters connect inline to the tracheostomy tube to enable end-tidal CO2 measurement, allowing noninvasive evaluation of ventilation status, particularly in pediatric or home-ventilated patients where portable devices like the EMMA capnograph use low-dead-space adapters for accurate readings. ^[33] These adapters facilitate correlation between end-tidal and venous CO2 levels, aiding in respiratory monitoring without disrupting the airway circuit. ^[34] Speaking valves, such as the Passy-Muir valve, attach to the tube's outer hub as one-way devices that permit inhalation through the tracheostomy while redirecting exhalation through the upper airway to enable phonation via the vocal cords. ^[35] This valve improves communication, swallowing, and secretion clearance while potentially aiding ventilator weaning by restoring subglottic pressure, though it requires patient tolerance assessment and is contraindicated in severe upper airway obstruction. ^[30]

Surgical Procedures

Open Surgical Tracheotomy

The open surgical tracheotomy is a traditional procedure performed by surgeons to establish a secure airway through a controlled incision in the trachea, typically in controlled environments for optimal visualization and safety. It is indicated for patients requiring prolonged ventilation or those with anatomical challenges where less invasive methods may be unsuitable. The procedure is conducted in the operating room for elective cases, offering advantages such as enhanced exposure in complex neck anatomy, including obesity or prior surgical scarring, which facilitates precise dissection and reduces the risk of inadvertent injury to surrounding structures.^[2][36] Preoperative preparation begins with general anesthesia, often involving endotracheal intubation to maintain airway patency during the initial phases; in select cases with upper airway compromise, local anesthesia may be employed. The patient is positioned supine with neck extension, achieved using a shoulder roll or chest bump to hyperextend the neck and expose the anterior cervical region adequately. A sterile field is established in the operating room, including preparation of the skin from the mandible to the sternum with antiseptic solutions, draping to isolate the operative site, and assembly of the tracheostomy tray containing instruments such as scalpels, retractors, hemostats, and a cuffed nonfenestrated tracheostomy tube, along with suction apparatus and emergency airway equipment. Assessment of neck landmarks, including the cricoid cartilage and suprasternal notch, is performed to identify any vascular anomalies or anatomical variations.^[2][36] The surgical steps commence with a midline skin incision, either vertical (preferred for emergent access and reduced skin tethering) or horizontal (for better cosmetic outcomes), made approximately 1-2 cm inferior to the cricoid cartilage and extending 2-4 cm toward the suprasternal notch. Subcutaneous tissues are dissected bluntly with hemostats and electrocautery for hemostasis, followed by incision through the platysma muscle in the midline. The strap muscles (sternohyoid and sternothyroid) are separated along their median raphe and retracted laterally to expose the thyroid isthmus, which is mobilized, divided, and ligated if necessary to access the trachea without vascular compromise. A tracheal hook is used to elevate and stabilize the trachea, and a vertical or cruciate incision is made between the second and third tracheal rings to enter the airway lumen, avoiding the cricoid cartilage superiorly and first ring to prevent subglottic stenosis; stay sutures may be placed on the tracheal edges for retraction and emergency reintubation if needed.^[2][36] Finally, the endotracheal tube is withdrawn partially as the tracheostomy tube, loaded with its obturator, is inserted into the tracheal opening under direct visualization, ensuring proper alignment and depth. The obturator is removed, an inner cannula is placed if applicable, and the tube is secured to the skin with sutures or ties. Placement is confirmed by observing chest rise, auscultation of bilateral breath sounds, and end-tidal CO2 detection via connection to the anesthesia circuit. This methodical approach ensures a stable stoma and immediate ventilatory support.^[2][36]

Percutaneous Dilatational Tracheotomy

Percutaneous dilatational tracheotomy (PDT) is a minimally invasive bedside procedure commonly performed in intensive care units (ICUs) to establish a secure airway in critically ill patients requiring prolonged mechanical ventilation. It utilizes the Seldinger technique, involving needle puncture of the trachea, guidewire insertion, serial dilatation, and subsequent placement of a tracheostomy tube, often under fiberoptic bronchoscopic guidance to ensure precise positioning and minimize risks such as posterior tracheal wall injury. Ultrasound guidance may be used adjunctively for needle insertion to enhance precision and safety, particularly in patients with difficult anatomy.^[37] This method, first described by Ciaglia et al. in 1985, has become a standard alternative to open surgical tracheotomy, particularly in stable ICU patients, due to its procedural simplicity and reduced need for operating room resources.^[38] The procedure begins with the patient positioned supine with neck extension to optimize anatomical exposure, followed by administration of sedation, analgesia, and neuromuscular blockade to facilitate tolerance. After local anesthesia infiltration and a small transverse skin incision (typically 2-2.5 cm) between the cricoid cartilage and sternal notch, pretracheal tissues are bluntly dissected. The endotracheal tube is withdrawn just below the vocal cords under direct laryngoscopy, and a fiberoptic bronchoscope is advanced to visualize the trachea. A 14- to 18-gauge sheathed needle is then inserted percutaneously into the trachea, ideally between the second and fourth tracheal rings, with placement confirmed by air aspiration and bronchoscopic visualization. A flexible guidewire is passed through the needle sheath into the trachea, the needle is removed, and serial dilators (such as Ciaglia's multiple tapered dilators or the single-step Blue Rhino dilator) are advanced over the guidewire to create a tract. Finally, the tracheostomy tube, loaded onto a dilator or guidewire, is inserted, secured, and confirmed via bronchoscopy or end-tidal CO₂ monitoring. The entire process typically takes 10-20 minutes when performed by experienced operators.^[39][40] Key advantages of PDT include its feasibility at the bedside, which eliminates the risks associated with transporting critically ill patients to the operating room—such as hemodynamic instability or accidental extubation, reported in up to 33% of transfers—and reduces overall procedural costs by approximately 50% compared to open techniques.^[39] It also involves less tissue dissection, leading to lower rates of wound infection (2.3% versus 10.7% for surgical tracheotomy) and improved cosmetic outcomes with minimal scarring.^[39][41] In select ICU patients without coagulopathy, PDT is associated with reduced bleeding risk due to the controlled puncture and dilatation approach.^[40] Contraindications for PDT encompass absolute barriers such as uncontrolled coagulopathy (e.g., platelet count below 50,000/μL or INR greater than 1.5 without correction), active infection at the site, or anatomically challenging pediatric cases (e.g., infants with small, compressible airways), as well as relative factors like difficult neck anatomy (obesity, short neck), unstable cervical spine, or high ventilatory requirements that preclude safe bronchoscopy.^[39][40][42] Evidence from systematic reviews supports PDT's safety and efficacy in ICU settings, demonstrating equivalence to open surgical tracheotomy in overall complication rates, mortality, and serious adverse events such as major bleeding or tube misplacement, based on meta-analyses of over 20 randomized controlled trials involving more than 1,600 patients.^[41] For instance, a Cochrane review found no significant difference in procedure-related mortality (odds ratio 0.52, 95% CI 0.10-2.60) or intraoperative life-threatening events (risk ratio 0.93, 95% CI 0.57-1.53), though PDT showed moderate-quality evidence for a 76% reduction in wound infections (risk ratio 0.24, 95% CI 0.15-0.37).^[41] Earlier meta-analyses similarly reported lower perioperative bleeding (odds ratio 0.14) and stomal infection rates (odds ratio 0.02) with PDT, affirming its suitability for non-emergent cases in experienced hands.^[40] Compared to open methods, PDT offers logistical benefits without compromising safety in appropriately selected patients.^[41]

Risks, Complications, and Management

Intraoperative and Immediate Risks

Bleeding represents one of the most common intraoperative complications during tracheotomy, with an incidence of approximately 5% for any degree of hemorrhage, though major bleeding is rare.^[2] This risk often stems from injury to the anterior jugular veins, thyroid vessels such as the thyroidea ima artery, or paratracheal venous structures during dissection.^{[43] [2]} In patients with coagulopathy, the likelihood increases, underscoring the need for preoperative correction of platelet counts to above 50,000 per microliter and normalization of coagulation parameters.^[2] Management typically involves meticulous hemostasis through ligation of larger vessels like the anterior jugular or thyroid arteries and cauterization of smaller venous branches to prevent ongoing blood loss.^[43] Airway compromise is another immediate peril, primarily arising from the creation of a false passage or accidental dislodgement of the tracheostomy tube, which can result in obstruction, subcutaneous emphysema, or pneumothorax.^[2] These events are particularly hazardous in the early postoperative period when the tracheostomy tract is immature, potentially leading to rapid desaturation if the tube enters pretracheal soft tissue instead of the trachea.^[44] To mitigate this, surgeons often employ lateral tracheal stay sutures through the third or fourth tracheal rings, which allow traction to reopen the stoma and guide safe reinsertion of the tube during accidental decannulation.^{[2] [45]} Anesthesia-related risks during tracheotomy are heightened in critically ill patients, including hypoxia from inadequate ventilation or procedural delays and cardiovascular instability due to underlying comorbidities or vagal stimulation.^[2] Hypoxemia occurs in up to 26% of intubated ICU patients undergoing similar airway interventions, often exacerbated by difficult laryngoscopy or positive pressure ventilation challenges.^[46] Close hemodynamic monitoring, preoxygenation, and bronchoscopic guidance are essential to maintain oxygen saturation above 90% and stabilize blood pressure in these high-risk scenarios.^[2]

Long-Term Complications and Care

Long-term complications of tracheotomy primarily involve structural and infectious changes to the airway that develop weeks to months after placement. Tracheal stenosis, a narrowing of the trachea due to scar tissue formation from cuff pressure or improper stoma positioning, affects 1-21% of patients, with rates as low as 1-2% in modern series using low-pressure cuffs.^[47] It may require endoscopic dilation, laser therapy, or surgical reconstruction for management. Granulation tissue, an overgrowth of inflamed tissue at the stoma or within the tracheal lumen, can cause partial obstruction and is often treated with silver nitrate cauterization or excision to restore airflow. Late-onset infections, including bacterial tracheitis, arise from persistent microbial colonization at the tracheostomy site and are addressed through systemic antibiotics, local debridement, and enhanced hygiene protocols. Delayed bleeding, typically from erosion of the tube tip into vascular structures such as the innominate artery, manifests as recurrent minor hemorrhages progressing to life-threatening hemoptysis in tracheoinnominate fistula cases, with prompt hyperinflation of the cuff and surgical ligation essential for survival. Patients and caregivers should monitor for signs requiring urgent medical attention, which include severe breathing difficulty, heavy bleeding from the stoma, high fever, accidental dislodgement or removal of the tube, and indications of infection such as pus drainage or intense redness around the site. Prompt recognition and seeking immediate medical intervention are crucial to prevent serious complications.^[48][49] Effective long-term care focuses on preventing these complications through structured maintenance and rehabilitation. Routine tracheostomy tube changes typically occur every 4-12 weeks following initial maturation of the stoma tract (5-7 days post-procedure), depending on patient factors and manufacturer guidelines, reducing risks of secretion accumulation, infection, and tissue irritation.^[50] Humidification of inspired air via heat-moisture exchangers or nebulizers is vital to maintain mucosal integrity and prevent crusting of secretions that could lead to obstruction. Speaking training involves the use of one-way speaking valves attached to the tube, which permit inhalation through the stoma but redirect exhalation upward for vocalization, often combined with speech-language pathology sessions to improve communication and swallowing. Decannulation, the removal of the tube, is considered when patients tolerate cuff deflation trials without distress, demonstrate 48-72 hours of capped tube occlusion, show no aspiration on videofluoroscopy, and have confirmed upper airway patency via endoscopy. Pediatric tracheotomy patients face elevated risks of long-term complications due to anatomical vulnerabilities. Tracheal stenosis occurs more frequently in children, with rates up to 50% in some cohorts, attributed to the narrower tracheal diameter and greater susceptibility to ischemic injury from oversized tubes or prolonged intubation. Tube sizing must be precisely tailored to the child's age, weight, and tracheal dimensions using established age-based formulas, such as internal diameter (mm) ≈ 4 + (age in years / 4) for uncuffed tubes, or direct measurement to avoid excessive pressure and subsequent scarring.^[51]

Historical Development

Ancient and Medieval Eras

The earliest documented references to procedures akin to tracheotomy originate in ancient Egyptian medicine. The Ebers Papyrus, dating to approximately 1550 BC, describes interventions for throat obstructions that resemble early forms of airway access.^[4] Subsequent references appear in ancient Indian medicine. The Sushruta Samhita, a foundational text on surgery attributed to the physician Sushruta and composed around 600 BCE, describes a surgical incision into the trachea to alleviate airway obstruction, particularly from conditions such as goiter or foreign body aspiration. This technique involved careful dissection to access the windpipe while avoiding major vessels, reflecting an early understanding of cervical anatomy and the need for immediate airway intervention in life-threatening scenarios.^[4] In the Greco-Roman world, tracheotomy faced significant opposition from influential physicians like Hippocrates (c. 460–370 BCE), who cautioned against neck incisions due to risks of severe hemorrhage, tracheal collapse, and fatal complications from severing nearby structures. Despite this, Asclepiades of Bithynia (c. 124–40 BCE), a Greek physician practicing in Rome, is credited with performing the first elective (non-emergency) tracheotomy, reportedly using a transverse incision to relieve chronic airway obstruction in a patient. This innovation was later referenced by Galen (c. 129–216 CE), who provided detailed anatomical descriptions of the larynx and trachea but did not advocate for the procedure himself, contributing to its sporadic and controversial adoption in antiquity.^[52][53] During the medieval era, tracheotomy saw extremely limited application in Europe, largely due to entrenched medical skepticism inherited from Hippocratic and Galenic traditions. The procedure's rarity is evidenced by the absence of widespread documentation, with most surgical texts prioritizing less invasive remedies for respiratory distress. In contrast, Islamic medicine preserved and occasionally advanced ancient knowledge; Albucasis (Abu al-Qasim al-Zahrawi, 936–1013 CE), in his comprehensive surgical encyclopedia Kitab al-Tasrif, described suturing a self-inflicted tracheal laceration in a servant girl who survived without long-term airway compromise, illustrating the trachea's healing potential and influencing later surgical practices in the Islamic world.^[53]

16th–19th Centuries

In the 16th century, the practice of tracheotomy gained renewed attention in Europe through the work of Italian physicians. Antonio Musa Brasavola performed and documented the first successful tracheotomy in 1546 on a patient suffering from quinsy, a severe peritonsillar abscess causing airway obstruction; he made an incision into the trachea below the larynx to relieve the blockage, marking a significant advancement over sporadic ancient attempts.^[54] Later in the century, anatomist Hieronymus Fabricius ab Aquapendente (1537–1619) refined the technique by advocating a vertical incision through the tracheal rings and introducing the use of a flanged cannula tube to maintain airway patency, thereby reducing complications from wound closure and facilitating breathing in cases of laryngeal obstruction.^[53] During the 17th and 18th centuries, tracheotomy saw intermittent application amid growing debates on its indications, timing, and ethical implications, particularly for pediatric conditions like croup. French surgeon Nicolas Habicot reported four successful cases in 1620, including uses for laryngeal inflammation, and recommended a flattened tube design to minimize tracheal trauma.^[53] By the mid-18th century, Scottish physician Francis Home endorsed tracheotomy as a treatment for croup in children in 1765, arguing it could avert fatal asphyxia, though widespread fear of the procedure's risks—such as infection and hemorrhage—limited its adoption, sparking ethical discussions on intervening in life-threatening airway crises versus conservative management.^[53] These debates centered on optimal timing, with proponents urging early intervention to bypass obstructions while critics highlighted high mortality and questioned its morality in vulnerable young patients. The 19th century brought further standardization of tracheotomy, driven by Armand Trousseau's influential work on diphtheria in the 1830s and 1840s. Trousseau, a student of Pierre Bretonneau, performed his first tracheotomy in Paris in 1831 and by 1855 had reported outcomes from over 200 cases, primarily in children with diphtheritic croup, achieving approximately 22% survival that underscored the procedure's potential despite persistent challenges like postoperative care.^[55] The introduction of ether anesthesia in the 1840s, first demonstrated publicly in 1846, transformed tracheotomy into a more controlled operation, enabling precise incisions and reducing patient distress, which contributed to its broader acceptance and integration into surgical practice for acute airway emergencies.^[56]

20th Century and Modern Advances

In the early 20th century, American laryngologist Chevalier Jackson significantly advanced tracheotomy techniques by standardizing the surgical tracheostomy procedure, emphasizing precise anatomical dissection and vertical incisions between tracheal rings to minimize complications such as bleeding and infection.^[57] His refinements, detailed in publications around 1909 and refined through the 1920s, reduced operative mortality from over 50% to approximately 5% by advocating for elective timing and improved postoperative care.^[58] During World War II, tracheotomy emerged as a critical intervention in trauma management, particularly for soldiers with maxillofacial injuries, chest trauma, and airway obstruction from battlefield wounds, where it facilitated ventilation and reduced mortality in forward surgical units.^[59] Mid-century innovations included the introduction of cuffed tracheostomy tubes in the 1940s, pioneered by F.J. Murphy, which featured an inflatable cuff to seal the trachea and prevent aspiration during mechanical ventilation, marking a shift toward safer long-term airway support in critically ill patients.^[60] In 1969, F.J. Toye and J.D. Weinstein developed the first percutaneous tracheostomy device, utilizing a Seldinger-like guidewire and tapered dilator for minimally invasive cannula insertion, laying the groundwork for bedside procedures that avoided large incisions.^[61] In the modern era post-2000, fiberoptic bronchoscopy has become routinely integrated into percutaneous dilatational tracheostomy (PDT) to provide real-time visualization of tracheal entry, reducing risks like posterior wall injury and paratracheal placement by up to 50% in guided procedures.^[62] Randomized controlled trials (RCTs) and meta-analyses comparing PDT to open surgical tracheostomy (OST) demonstrate PDT's advantages, including lower rates of wound infection (odds ratio 0.28) and stoma inflammation, shorter procedure times (average 10-15 minutes less), and reduced bleeding, though OST remains preferred in anatomically challenging cases.^[63] During the COVID-19 pandemic in the 2020s, updated guidelines from multidisciplinary panels recommended delaying tracheotomy until 14-21 days post-intubation in stable patients to minimize aerosol generation and infection risk to healthcare workers, with bronchoscopy-guided PDT adopted widely for its safety in infected cohorts, achieving complication rates below 10% when performed under enhanced personal protective equipment protocols.^[64]

Societal and Cultural Context

Ethical and Legal Considerations

Ethical considerations in tracheotomy decisions often center on obtaining consent from unconscious or incapacitated patients, where surrogates must represent the patient's best interests based on prior expressed wishes or substituted judgment. In such cases, physicians are ethically obligated to seek consent from a suitable surrogate decision-maker, as unconscious patients lack decision-making capacity. This process aligns with principles of respect for autonomy and beneficence, ensuring that interventions like tracheotomy do not violate patient values.^[65][66] Assessing futility in terminal cases presents another ethical challenge, requiring clinicians to evaluate whether tracheotomy offers meaningful benefit or merely prolongs suffering without improving quality of life. Ethical frameworks emphasize that tracheostomy should not proceed if there is a moderate to high degree of certainty that it is medically futile, prioritizing non-maleficence and avoiding interventions that provide no reasonable hope of recovery. In terminal scenarios, such as advanced neurologic injury, shared discussions may lead to withholding tracheotomy to honor goals of comfort care over aggressive prolongation of life.^[67][68] Resource allocation during pandemics introduces justice-based ethical dilemmas, particularly when tracheotomy resources like ventilators and surgical capacity are limited, necessitating prioritization criteria that balance equity and utility. For instance, during the COVID-19 pandemic, guidelines recommended delaying elective tracheostomies to conserve personal protective equipment and beds, while prioritizing patients with higher likelihood of recovery to maximize overall benefit.^[69] This approach underscores the ethical imperative to avoid discrimination and ensure transparent, evidence-based rationing.^[70] Legally, informed consent is a cornerstone requirement for tracheotomy, mandating that patients or surrogates receive comprehensive information on risks, benefits, and alternatives to enable autonomous decisions. Failure to obtain proper consent can constitute negligence, exposing providers to malpractice liability, particularly in cases of procedural errors such as improper tube placement leading to airway obstruction or infection. Litigation analyses reveal that post-operative negligence, including tube dislodgement or mucous plugging, accounts for a significant portion of tracheotomy-related lawsuits, highlighting the need for meticulous documentation and adherence to standards of care.^[71][72][73] Advance directives play a critical legal role in tracheotomy decisions, allowing patients to specify preferences regarding invasive procedures like tracheotomy in advance, which surrogates and providers must honor if the patient becomes incapacitated. These documents, including living wills, legally bind healthcare teams to respect refusals of life-sustaining interventions in terminal conditions, reducing conflicts and potential litigation over substituted judgments. Courts generally uphold valid advance directives as expressions of patient autonomy, though challenges arise if directives are ambiguous or outdated.^[74][75] Professional guidelines from organizations like the American Medical Association (AMA) and World Health Organization (WHO) advocate for shared decision-making in cases of prolonged mechanical ventilation leading to tracheotomy consideration. The AMA emphasizes collaborative processes involving patients, families, and providers to align interventions with patient values, especially when transitioning from short-term intubation. Similarly, WHO frameworks promote equitable, transparent shared decision-making during resource-scarce scenarios, integrating ethical principles to guide discussions on tracheotomy timing and necessity.^[71][76][70]

Representation in Media and Public Perception

Tracheotomies are frequently depicted in television and film as high-stakes emergency procedures performed by untrained individuals using improvised tools like ballpoint pens, emphasizing dramatic tension over medical realism. Such portrayals, seen in shows like Grey's Anatomy, House M.D., ER, and MAS*H, as well as films including Anaconda and Saw V, often involve characters stabbing the neck to create an airway without proper sterile technique or equipment, contrasting sharply with actual surgical practice that requires trained professionals and controlled settings.^[77] These dramatizations contribute to a trope known as "instant drama just add tracheotomy," where the procedure serves as a plot device to heighten suspense, appearing in over 90 medical dramas produced in North America since 1951.^[77] In contrast, some productions strive for greater authenticity by consulting medical experts and historical records. For instance, the BBC series Call the Midwife featured a researched depiction of an emergency tracheotomy on a pregnant woman with diphtheria in a 1950s setting, using period-appropriate equipment and clinical advice to balance procedural accuracy with narrative depth.^[78] Biographical films like The Theory of Everything (2014) portray tracheotomy more realistically in the context of chronic illness, showing Stephen Hawking's procedure as a life-sustaining intervention amid progressive ALS, highlighting long-term adaptation rather than acute drama. Public perception of tracheotomy often involves stigma, with the visible neck tube perceived as disfiguring and leading to social isolation, altered body image, and challenges in interpersonal relationships. Patients report profound impacts on self-image and sexuality, with the tracheostomy tube acting as a barrier to social interactions and contributing to anxiety in public settings.^[79] Employment difficulties are common, particularly for manual laborers, as the tube is viewed as a marker of vulnerability, prompting some to abandon jobs or seek alternatives.^[79] This stigma has been exacerbated by pandemics, where tracheostomy patients face prejudice due to fears of airborne transmission, such as SARS-CoV-2, leading to avoidance by others and heightened emotional distress. Surveys indicate that up to 93% of tracheostomy patients and families experience fear or anxiety during the COVID-19 pandemic.^[80] Inaccurate media representations further reinforce negative stereotypes, portraying individuals with tracheostomies as frail or burdensome, which perpetuates unease and devaluation in society.^[77]
