ICD-9-CM86.09

An escharotomy is a surgical procedure used to treat full-thickness (third-degree) circumferential burns. In full-thickness burns, both the epidermis and the dermis are destroyed along with sensory nerves in the dermis. The tough leathery tissue remaining after a full-thickness burn has been termed eschar. Following a full-thickness burn, as the underlying tissues are rehydrated, they become constricted due to the eschar's loss of elasticity, leading to impaired circulation distal to the wound. An escharotomy can be performed as a prophylactic measure as well as to release pressure, facilitate circulation and combat burn-induced compartment syndrome.

An escharotomy is performed by making an incision through the eschar to expose the fatty tissue below. Due to the residual pressure, the incision will often widen substantially.

Overview

[edit]
a) Fasciotomy b) Escharotomy in a child with third degree burns. A motorized dermatome is used to do the first debridement of the eschar.

Full-thickness circumferential and near-circumferential skin burns result in the formation of a tough, inelastic mass of burnt tissue (eschar). The eschar, by virtue of this inelasticity, results in the burn-induced compartment syndrome. This is caused by the accumulation of extracellular and extravascular fluid within confined anatomic spaces of the extremities or digits. The excessive fluid causes the intracompartmental pressures to increase, resulting in collapse of the contained vascular and lymphatic structures and, hence, loss of tissue viability. The capillary closure pressure of 30 mm Hg, also measured as the compartment pressure, is accepted as that which requires intervention to prevent tissue death. If ischemia (poor blood flow) persists for over six hours, then the irreversible process of muscle necrosis will begin.[2]

The circumferential eschar over the torso can lead to significant compromise of chest wall excursions and can hinder ventilation. Abdominal compartment syndrome with visceral hypoperfusion is associated with severe burns of the abdomen and torso. Due to the primarily diaphragmatic breathing done by children, anterior burns may be enough to warrant an escharotomy.[3] Similarly, airway patency and venous return may be compromised by circumferential burns involving the neck.

Escharotomy is the surgical division of the nonviable eschar, which allows the cutaneous envelope to become more compliant. Hence, the underlying tissues have an increased available volume to expand into, preventing further tissue injury or functional compromise.

Indications

[edit]

Indications for emergency escharotomy are the presence of a circumferential eschar with one of the following:

  • Impending or established vascular compromise of the extremities or digits.
  • Impending or established respiratory compromise due to circumferential torso burns.[4]
  • Severely burned extremities should be elevated and range of motion exercises performed every 15–30 minutes as tolerated by the patient. This can help to minimize tissue edema and elevated tissue pressures.

Neurovascular integrity should similarly be monitored frequently and in a scheduled manner. Capillary refilling time, Doppler signals, pulse oximetry, and sensation distal to the burned area should be checked every hour.[5] Limb deep compartment pressures should be checked initially to establish a baseline. Subsequently, any increase in capillary refill time, decrease in Doppler signal, or change in sensation should lead to rechecking the compartment pressures. Compartment pressures greater than 30 mm Hg should be treated by immediate decompression via escharotomy and fasciotomy, if needed.[4]

Procedure

[edit]

During an escharotomy the patient is often sedated despite the insensible eschar. The burnt skin is incised down to the subcutaneous fat and into the healthy skin (up to 1 cm). The incisions should be deep enough to release all restrictive effects from the eschar. The operation can be performed on the trunk, limbs, or neck, all while avoiding critical nerves, veins, and vessels.[3] Following the operation the wounds are dressed primarily with an absorbent, antimicrobial material, then wrapped lightly in a bandage. Elevation (if possible) and observation are encouraged.[5]

Escharotomy is an emergency surgical procedure that involves incising through the —the tough, inelastic layer of dead tissue formed in full-thickness burns—to release its constrictive effects and prevent . This intervention is essential for restoring blood flow in affected limbs or improving chest wall expansion and ventilation in torso burns, thereby mitigating risks of tissue necrosis, organ failure, or respiratory compromise. It is typically performed in cases of circumferential burns where the eschar acts as a non-compliant barrier due to and fluid shifts. The primary indications for escharotomy include clinical signs of vascular compromise in extremities, such as the "six Ps" (pain, , , , poikilothermia, and pulselessness), or elevated compartment pressures exceeding 30 mm Hg. In thoracic or abdominal burns, it is warranted when restrictive eschar impairs breathing, evidenced by reduced tidal volumes or increased respiratory effort, potentially leading to with intra-abdominal pressures over 20 mm Hg. The procedure is ideally conducted emergently within the first 48 hours post-injury, often in an operating room or intensive care setting, and may precede or accompany excision and . During escharotomy, longitudinal incisions are made along predefined lines to spare major neurovascular structures, extending from unburned through the into the subcutaneous fat but not penetrating the underlying unless is required. Common sites include the mid-axial lines of the upper and lower limbs, a "" configuration across the chest, or bilateral flank incisions for the ; digits may require smaller releases. Tools such as a , electrocautery, or cutting are used under sterile conditions, with post-procedure monitoring via Doppler , , and wound dressings like alginate to manage . While escharotomy is lifesaving, it carries risks including significant bleeding from vascular structures, of the open , and potential neurovascular injury (e.g., to the ulnar or peroneal nerves). Inadequate decompression can result in ongoing ischemia, myonecrosis, or the need for , with overall complication rates influenced by burn severity and timely intervention; mortality from untreated in severe burns can reach 75%. Subsequent care often involves wound coverage and rehabilitation to optimize functional outcomes.

Background

Definition and Purpose

Escharotomy is a surgical procedure that involves making incisions through the full-thickness of a down to the subcutaneous fat layer to relieve circumferential caused by the rigid, non-yielding burned tissue. This intervention is typically indicated for third-degree burns where the eschar forms a tight band around limbs, digits, or the , restricting underlying tissue expansion. The primary purpose of escharotomy is to prevent tissue ischemia, , and potential organ compromise by decompressing the edematous tissues beneath the , thereby allowing for the expansion of viable underlying structures and restoring adequate blood flow and ventilation. In cases of limb involvement, it alleviates vascular compression that could lead to distal hypoperfusion, while for thoracic eschar, it mitigates restrictive effects on respiratory . By promptly releasing this pressure, the procedure helps avert irreversible muscle and nerve damage. Escharotomy differs from in that it targets only the skin and subcutaneous without incising the deeper fascial layers, focusing solely on superficial decompression rather than addressing intramuscular compartment pressures. It is performed emergently when signs of ischemia are present, as delays exceeding 6 hours can result in irreversible due to prolonged tissue hypoperfusion.

Historical Development

The concept of escharotomy traces its origins to the early , when Wilhelm Fabricius Hildanus, also known as Fabry of Hilden and regarded as the father of German surgery, first described the procedure in 1607 for relieving constriction caused by . In his seminal work De Combustionibus, Hildanus advocated incisions into burn eschars to drain and alleviate pressure, marking the initial recognition of the technique as a means to address circulatory compromise in burn injuries. The modern adoption of escharotomy gained momentum in the mid-20th century, particularly following , when increased burn trauma cases from military conflicts and industrial accidents prompted advancements in burn care protocols. In 1951, Thomas G. Blocker and Curtis P. Moyer recommended escharotomy specifically for constricting upper extremity s during a on burns, emphasizing its role in preventing ischemia through early decompression. This was further endorsed by A. B. Wallace in 1955, who advocated multiple incisions in the eschar to address distal ischemia while preserving a dry wound surface, integrating the procedure into standard emergency burn management. By the late , escharotomy had evolved from rudimentary incision methods into a standardized intervention, reflecting broader improvements in surgical techniques and unit protocols. Its formal classification in medical coding systems, such as the assignment of ICD-9-CM code 86.09 for "other incision of skin and " including escharotomy, occurred in the 2001 update to ICD-9-CM (effective October 1, 2000), building on the implementation of ICD-9 in 1979 and subsequent refinements, facilitating consistent documentation and reimbursement in clinical practice.

Pathophysiology

Eschar Formation in Burns

Eschar formation is a critical pathological process in severe injuries, particularly in full-thickness burns, where intense heat induces across multiple skin layers. In the zone of —the area closest to the heat source—proteins denature rapidly, leading to irreversible and vascular , which halts blood flow and creates a necrotic barrier. This results in the development of eschar, a tough, leathery composed of denatured , necrotic tissue, and dried , typically manifesting within hours of injury as the skin appears dry, waxy, and insensate. Full-thickness, or third-degree, burns are the primary context for eschar formation, as they extend through the entire and into the , destroying adnexal structures like hair follicles and sweat glands. Unlike superficial or partial-thickness burns, which may re-epithelialize, these injuries produce a non-viable that cannot regenerate, often presenting as white, charred, or leathery tissue without blanching or sensation due to nerve destruction. The eschar's formation is exacerbated by the burn's depth, where temperatures exceeding 70°C for seconds cause immediate protein , distinguishing it from shallower burns that lack this inelastic covering. Contributing to the eschar's pathological impact is the rapid increase in permeability triggered by inflammatory mediators such as , prostaglandins, and , which promote and fluid leakage from the intravascular space into the interstitial tissues. This leads to substantial accumulation beneath the rigid eschar, often peaking within 24-48 hours post-injury, as fluid further amplifies the volume shift. The inelastic nature of the eschar prevents natural tissue expansion in response to this swelling, creating a constrictive effect that elevates interstitial pressures. A key threshold for vascular compromise occurs when compartment pressures surpass 30 mm Hg, exceeding the closing pressure of capillaries and risking ischemia, which underscores the eschar's role in downstream .

Compartment Syndrome Mechanisms

In burn injuries, particularly those involving circumferential full-thickness burns, the formation of —a rigid, inelastic layer of dead tissue—creates a constricting barrier that impedes tissue expansion and elevates intracompartmental . This buildup occurs as fluid accumulates due to increased permeability and aggressive fluid , often peaking within the first 48 hours post-injury. When intracompartmental surpasses the (typically exceeding 30 mm Hg), it compromises arterial inflow and venous outflow, leading to tissue ischemia. In extremities and digits, this manifests as limb ischemia, where the acts like a , restricting blood flow distally and potentially causing irreversible muscle and nerve damage if unrelieved. The systemic pathophysiology of burn-induced compartment syndrome is exacerbated by the global hypermetabolic response, which involves catecholamine surge, increased metabolic rate, and widespread inflammation, further promoting edema and fluid shifts that intensify compartmental pressures. In the torso, eschar constriction limits chest wall excursion, reducing tidal volume and contributing to respiratory failure by impairing ventilation and increasing the work of breathing. Neck eschar can similarly obstruct the airway and hinder venous return from the head, compounding circulatory compromise. These mechanisms highlight the eschar's role as the primary initiator, transforming local burn pathology into potentially life-threatening systemic effects. Time is critical in this process, as sustained ischemia beyond 6 hours can lead to muscle , releasing and causing , which in turn risks acute renal failure through tubular obstruction and toxicity. Decompression is mandated when compartment pressures exceed 30 mm Hg to restore and prevent these sequelae, underscoring the emergent nature of intervention in affected areas.

Indications and Assessment

Clinical Signs Requiring Intervention

Escharotomy is primarily indicated for patients with circumferential full-thickness burns of the limbs, chest, or that result in clinical signs of neurovascular or respiratory compromise, particularly within the first 24 to 48 hours post-injury when formation peaks. These burns create a non-compliant that acts as a constricting band, leading to observable symptoms necessitating urgent intervention to prevent irreversible tissue damage. In the extremities, clinical signs requiring escharotomy include diminished or absent distal pulses detected by palpation or Doppler ultrasound, prolonged capillary refill time exceeding 2 seconds, paresthesia manifesting as numbness or tingling, pallor of the distal skin, and coolness to the touch compared to non-burned areas. These symptoms indicate progressive ischemia due to vascular compression, often progressing to the "6 Ps" of compartment syndrome: pain, pallor, paresthesia, paresis, poikilothermia, and pulselessness. Early detection through hourly neurovascular assessments, including monitoring of sensation, motor function, and distal oxygen saturation below 95%, is critical to identify compromise before irreversible injury occurs. For torso involvement, particularly circumferential burns of the chest or , signs include respiratory distress characterized by , use of accessory muscles for breathing, shallow or reduced due to chest wall rigidity, and increased ventilator pressures if mechanically ventilated. and bilateral reduced air entry may also signal impending ventilatory failure, especially in infants under 12 months who rely on . Additional indicators of neurovascular compromise warranting escharotomy involve digits, where similar signs of ischemia such as or absent flow necessitate targeted incisions. These presentations underscore the need for vigilant monitoring protocols in burn units to facilitate timely intervention.

Diagnostic Evaluation

Diagnostic for escharotomy primarily involves confirming the presence of in burn patients through a combination of clinical assessment and objective measurements to determine the need for intervention. The process begins with a thorough to identify signs of circulatory or respiratory compromise caused by circumferential . Key components include palpation of the affected area to assess tissue firmness, which in full-thickness burns presents as leathery, waxy, and non-pliable texture indicative of underlying pressure buildup. Sensory and motor testing is essential, evaluating for , numbness, weakness, or , often summarized by the "6 Ps" of : pain disproportionate to injury, , , , poikilothermia (coolness), and pulselessness as a late finding. Additionally, Doppler is used to detect arterial signals in distal extremities; diminished or absent Doppler signals suggest vascular compromise requiring urgent . Intracompartmental pressure measurement provides a more objective confirmation of when physical findings are equivocal, particularly in sedated or intubated patients where clinical signs may be unreliable. Specialized devices, such as the Intra-Compartmental Pressure Monitor or a simple needle-transducer system connected to an , are inserted into the affected compartment to measure levels. A compartment exceeding 30 mm Hg, or a delta (diastolic minus compartment ) of less than 30 mm Hg, is widely accepted as a threshold indicating the need for escharotomy to prevent tissue ischemia and . In burn-specific contexts, thresholds may be adjusted slightly higher, such as 35 mm Hg, based on perfusion status, but pressures above 30 mm Hg generally prompt intervention to restore circulation. Adjunct diagnostic tools support the primary evaluation but are not routinely required unless specific complications are suspected. on distal digits or limbs helps monitor tissue perfusion, with saturations below 95% or 90% signaling potential inadequacy that may necessitate escharotomy. For thoracic or abdominal , arterial blood gas analysis assesses respiratory involvement by detecting or from restricted ventilation, while peak airway pressures during provide indirect evidence of constriction. Routine imaging, such as or MRI, is generally avoided unless an underlying or vascular is suspected, as it may delay intervention without adding diagnostic value in straightforward burn-related . Serial assessments are critical in the intensive care setting to track progression, typically performed every 1 to 4 hours during initial , focusing on repeated physical exams, Doppler checks, and measurements to gauge response to fluid and formation. Escharotomy is contraindicated in superficial burns lacking evidence of circulatory or ventilatory compromise, as these do not develop significant compartmental and resolve with conservative management.

Procedure

Preoperative Preparation

Prior to performing an escharotomy, initial patient stabilization is essential to address life-threatening issues associated with severe burns. Airway management takes precedence, with early intubation recommended if there is evidence of inhalation injury or impending edema compromising ventilation. Fluid resuscitation follows the Parkland formula, administering 4 mL of lactated Ringer's solution per kilogram of body weight per percentage of total body surface area burned, with half given in the first 8 hours post-injury and the remainder over the next 16 hours, titrated to maintain urine output of 0.5–1 mL/kg/hour. Analgesia is provided using intravenous opioids such as morphine or fentanyl, with higher doses often required due to burn-related hypermetabolism and pain tolerance. Tetanus prophylaxis, including toxoid or immunoglobulin, is administered routinely as part of burn admission protocols to prevent infection in contaminated wounds. The procedure is typically conducted at the bedside in the or by a burn surgeon, plastic surgeon, or trained to ensure rapid intervention. A sterile field is established, with adequate lighting and suction equipment readily available to maintain visibility and clear any debris or during preparation. Instruments are prepared in advance, including a #10 blade for incision and electrocautery for , emphasizing the need for immediate access in emergency settings. Anesthesia options prioritize minimal delay, with local infiltration using lidocaine (often with epinephrine in unburned areas) sufficient for most cases since full-thickness lacks sensation; general or procedural sedation with agents like may be used for uncooperative patients or extensive procedures to preserve hemodynamic stability. Escharotomy is performed urgently, ideally within minutes of diagnosing circulatory or respiratory compromise from circumferential burns, to prevent irreversible tissue .

Incision Techniques and Sites

Escharotomy incisions are typically performed using a longitudinal approach, extending through the full thickness of the into the subcutaneous fat layer without penetrating deeper to the muscle , to relieve circumferential while minimizing damage to underlying structures. The procedure often employs a or electrocautery device for precision, with incisions made stepwise—starting on one side of the affected area and reassessing before proceeding—to allow for controlled decompression. In cases requiring greater expansion, such as in the , additional transverse or cross-hatch release cuts may be incorporated to facilitate full tissue separation, resulting in incisions that often gape open due to the release of underlying compartment pressure. Standard anatomical sites for escharotomy prioritize locations that avoid major neurovascular structures while effectively addressing constriction, with bilateral medial and lateral incisions recommended for limbs to ensure complete decompression. For the limbs, incisions are placed along the medial aspect of the upper arm (anterior to the medial epicondyle to avoid the ), the lateral forearm, the medial thigh, and the lateral leg (anterior to the fibular head to avoid the common peroneal nerve), extending proximally and distally to encompass the full length of the . On the torso, bilateral incisions follow the mid-axillary lines of the chest, typically connected by horizontal cuts across the upper chest and below the to enhance chest wall excursion. For the neck, incisions are positioned laterally and posteriorly to circumvent the and , ensuring safe decompression without vascular compromise. Incisions are generally 1-2 cm in depth to reach the subcutaneous fat and span the entire length of the constricting , extending approximately 1 cm beyond the margins for adequate relief. Following the incision, the affected limb is elevated to promote venous drainage and further reduce swelling. The 2023 National Burn Service guidelines (as of 2023), as evaluated in the Australasian Journal of Plastic Surgery, emphasize avoiding digital nerves and neurovascular bundles during hand escharotomies, recommending mid-axial incisions on the non-working border of fingers to protect these structures.

Immediate Postoperative Management

Following escharotomy, immediate postoperative monitoring focuses on verifying the procedure's efficacy and detecting early complications. Clinicians must reassess distal pulses, sensation, and compartment pressures to confirm improved , using for vascular flow and for tissue oxygenation. Continuous observation for , formation, or inadequate decompression—such as persistent ischemia or tissue firmness—is essential, with hourly vascular checks recommended for the first 12 to 24 hours. For chest or abdominal escharotomies, respiratory effort and ventilatory parameters should also be monitored to ensure relief of restrictive mechanics. Wound care begins promptly to minimize risk while promoting drainage. Incisions are loosely packed with sterile impregnated with topical antimicrobials, such as or bacitracin, and covered with nonadherent dressings like alginate or Xeroform to maintain a moist environment without closure, allowing for ongoing resolution. Affected limbs are elevated above heart level to reduce swelling, and the escharotomy sites are treated as part of the overall wound, with daily inspection for signs of or expansion. These measures align with standard protocols, avoiding primary closure to facilitate secondary interventions. Systemic support integrates escharotomy care with broader burn management to stabilize the patient. Fluid resuscitation follows established guidelines, such as the , with hourly monitoring of urine output (target 0.5–1 mL/kg/hour) to guide adjustments and prevent or over-resuscitation. Adequate control is provided using intravenous opioids or multimodal analgesia to facilitate patient comfort and cooperation during assessments, while prophylactic antibiotics are administered if there's heightened risk from open wounds or . Transfer to a specialized is prioritized for coordinated intensive care, including metabolic and renal support if or develops. Escharotomies are typically performed within the first 6 to 24 hours post- or urgently upon of compromise to address evolving circumferential , with monitoring extending up to 72 hours before transitioning to formal and .

Complications and Outcomes

Surgical Complications

Escharotomy, while essential for relieving circumferential constriction, carries risks of immediate perioperative complications due to the invasive nature of incising non-viable . These include hemorrhage, infection, and structural injuries, which can be mitigated through meticulous technique and vigilant monitoring. Bleeding is a primary concern, arising from incision into underlying vessels, and is typically managed with electrocautery during the procedure. This risk is amplified in burn patients with , a common driven by , , and dilutional effects from resuscitation fluids. Infection risk escalates post-escharotomy due to exposure of subcutaneous tissues, potentially leading to if underlying is present or if manipulation disseminates bacteria. Close wound surveillance in the initial 72 hours is crucial for prevention. Deep incisions may also cause neuromuscular , manifesting as or weakness from damage to superficial nerves like the ulnar or common peroneal. Other procedure-specific issues encompass inadvertent extension into the fascial layer, resulting in unintended , and incomplete release of the , which can precipitate distal from persistent ischemia. For torso escharotomies, inadequate incisions may fail to restore chest wall excursion, exacerbating respiratory compromise. Technique errors, such as imprecise incision placement along standard limb or thoracic sites, contribute to these risks but can be minimized with preoperative marking of vulnerable structures.

Long-Term Considerations

Timely escharotomy in patients with circumferential full-thickness burns significantly improves limb salvage rates when performed within the first 48 hours to prevent ischemia and . Despite this, potential long-term issues include hypertrophic scarring and functional deficits at incision sites, often necessitating for wound closure and reconstruction to minimize cosmetic and mobility impairments. In cases where escharotomy is inadequate or delayed, risks of muscle and persist, contributing to higher rates of secondary procedures. Rehabilitation following escharotomy emphasizes early to restore and prevent joint contractures, typically beginning within days of the procedure alongside control and splinting. Post-debridement is commonly required to achieve definitive wound closure, with sheet grafts preferred for visible areas like hands to reduce scarring; ongoing scar management, including compression garments and applications, supports functional recovery over 6-12 months. Multidisciplinary care, incorporating , aids in reintegration, though over 60% of severe survivors experience posttraumatic psychological challenges impacting long-term adherence. Prognosis after escharotomy is influenced by burn extent, with total (TBSA) exceeding 40% associated with poorer outcomes due to increased systemic complications and prolonged hypermetabolic response. Advanced age over 60 years and preexisting comorbidities, such as cardiac disease, further worsen recovery by extending hospital stays and elevating mortality risks. For example, in hand burns, escharotomy reduces risk from approximately 21% in untreated cases to 10% in managed cases, highlighting its role in averting irreversible limb loss.

Guidelines and Alternatives

Current Clinical Standards

Current clinical standards for escharotomy emphasize timely intervention to relieve circumferential full-thickness burns that compromise circulation, ventilation, or limb viability, guided by protocols from major health authorities updated between 2023 and 2025. The American Burn Association (ABA) guidelines also recommend escharotomy for circumferential full-thickness burns showing signs of compartment syndrome or ventilatory impairment, aligning with timely intervention within 24-48 hours. The Joint Trauma System Clinical Practice Guideline (CPG) for Burn Care, released in June 2025, provides recommendations tailored for military and deployed settings, prioritizing escharotomy when clinical signs of compartment syndrome or respiratory distress emerge, particularly within the first 48 hours post-injury to prevent irreversible tissue damage. Similarly, the Provincial Clinical Practice Guideline for Escharotomy in Burn Patients from British Columbia, issued in April 2025, stresses limb- and life-saving incisions for circumferential burns affecting extremities or the thorax, advocating for immediate assessment and procedure by trained personnel to restore perfusion and chest wall compliance. Standards for incision sites and postoperative monitoring are outlined in the Agency for Clinical Innovation (ACI) guide on Escharotomy for Burn Patients, updated in 2025, which specifies longitudinal incisions along limb axes and mid-axillary lines for the chest to avoid neurovascular structures while ensuring adequate decompression; continuous monitoring of distal pulses, , and ventilatory parameters is mandated post-procedure. For austere or field environments, the Wilderness Medical Society's 2025 Clinical Practice Guideline on Care of Patients in Remote Settings updates protocols to include escharotomy by non-specialists when evacuation is delayed, focusing on basic techniques with improvised tools and emphasizing rapid transfer to definitive care once feasible. Broader protocols align on early intervention, with escharotomy recommended within 48 hours of to address edema-induced constriction, as supported by established management consensus. for non-surgeons, including responders, is integral to these guidelines, particularly in resource-limited scenarios, to enable safe performance during the critical window before specialist arrival. A 2023 review in the Australasian Journal of refined incision locations based on anatomical evaluations, recommending adjustments to traditional sites—such as medial limb placements over lateral—to further minimize neurovascular risks while maintaining efficacy.

Emerging Approaches

Recent innovations in escharotomy management aim to minimize invasive incisions while effectively addressing in circumferential burns, leveraging selective tissue removal and advanced monitoring technologies. Enzymatic with bromelain-based agents, such as Nexobrid (anacaulase-bcdb), enables selective removal of nonviable in deep partial- and full-thickness circumferential burns, often obviating the need for traditional surgical incisions. In August 2024, the FDA approved Nexobrid for removal in adults with deep partial- and full-thickness thermal burns, expanding its clinical application. This approach lyses devitalized tissue while preserving viable , facilitating pressure release and improved in extremities. Clinical studies have demonstrated its safety and efficacy in preventing burn-induced , particularly when applied within 24-48 hours post-injury. For instance, in a 2022 multicenter , Nexobrid application in deep circumferential extremity burns achieved complete removal in over 90% of cases without systemic adverse effects, reducing the requirement for . Additionally, a 2019 prospective study confirmed its role in safely averting in upper extremity burns, with no reported infections or bleeding complications. Studies from 2022 to 2025 indicate that enzymatic lowers overall complication rates, including infections and the need for additional surgeries, in deep burns treated within 48 hours, with reductions in surgical interventions by up to 50% compared to standard care. In the DETECT trial (2023), early Nexobrid use resulted in fewer operative procedures and less blood loss, alongside a low profile. A 2024 retrospective analysis of hand burns further showed decreased surgical and improved functional outcomes. Non-surgical alternatives, such as (NPWT) and conservative tangential excision, offer viable options in select cases of circumferential to manage and promote decompression without full escharotomy. NPWT applies subatmospheric pressure to reduce swelling, enhance perfusion, and stabilize wounds, particularly useful post-initial or in less severe constrictions. A 2021 review highlighted its benefits in burn care for fluid removal and graft integration, potentially delaying or avoiding incisions in stable patients. Conservative tangential excision, involving superficial layer-by-layer removal of eschar, has emerged as an effective preventive and therapeutic strategy for heat-induced . A 2024 study in the Injury journal reported successful decompression in all treated cases using this minimally invasive method, with shorter operative times and preserved tissue viability compared to escharotomy. Advancements in precision and monitoring include ultrasound-guided techniques and AI-assisted systems to enhance decision-making and early intervention. Doppler ultrasound provides real-time assessment of vascular flow, guiding precise incision placement or confirming the need for escharotomy by detecting progressive ischemia in circumferential s. AI-driven tools integrate and clinical data for early detection of compartment risks, improving depth evaluation and predicting the necessity for decompression. A 2025 multicenter study found AI models, such as ChatGPT-4o, showed promising performance comparable to expert surgeons in description and , with scores up to 4.8/5.
