Thermal Burns

Evaluate thermal burns by confirming airway risk, measuring partial- and full-thickness TBSA accurately, initiating response-titrated resuscitation for major injury, controlling pain, protecting wounds, and transferring patients whose size, depth, location, or inhalation risk requires burn-center care.

Clinical question: How should physicians triage, quantify, resuscitate, and arrange definitive care for acute thermal burns?

First decisions

Identify airway threat, major burn physiology, and transfer needs

Manage significant burns as trauma while establishing injury size, depth, mechanism, and airway risk.PubMedBurn Resuscitation and Management(Archived) - StatPearls - NCBI Bookshelf

Begin with airway, breathing, circulation, exposure, analgesia, and removal from the heat source. In a severe flame burn, specifically assess for inhalation injury; inhalation injury increases fluid requirements, pulmonary complications, and mortality when it accompanies cutaneous thermal trauma.PubMedBurn Resuscitation and Management(Archived) - StatPearls - NCBI BookshelfScienceDirectEffect of inhalation injury on fluid resuscitation requirements after thermal injury - ScienceDirect

Do not attribute early hypotension solely to a burn. Burn shock develops during the first hours after injury; immediate hypotension should prompt evaluation for concurrent hemorrhage, traumatic injury, or another cause of shock.PubMedBurn Resuscitation and Management(Archived) - StatPearls - NCBI Bookshelf

Arrange specialized burn-center transfer for severe injury, including burns exceeding 10% TBSA and full-thickness burns, while continuing initial stabilization and resuscitation rather than delaying transfer for definitive wound procedures.JAMAAdherence to Burn Center Referral Criteria for Pediatric ...

Quantify injury

Estimate TBSA accurately before committing to a fluid rate

TBSA error can cause both under-resuscitation and clinically important fluid overload.nice org ukIntroduction | Mersey Burns for calculating fluid resuscitation volume when managing burns | Advice | NICEPubMedRule of Nines - StatPearls - NCBI Bookshelf

Estimate TBSA using partial-thickness and full-thickness areas. The Rule of Nines is rapid for adult initial assessment, whereas the Lund-Browder chart adjusts for the age-related body proportions of infants and children. Use the patient’s palm including fingers as approximately 1% TBSA for scattered or small burns.cks nice org ukAssessment | Diagnosis | Burns and scalds - CKS - NICEnice org ukIntroduction | Mersey Burns for calculating fluid resuscitation volume when managing burns | Advice | NICEPubMedRule of Nines - StatPearls - NCBI Bookshelf

Use the Lund-Browder chart rather than unmodified adult proportions in children because head and leg surface-area proportions vary with age. Reassess TBSA after exposure, cleaning, and serial examination when the initial estimate is uncertain; Rule of Nines estimates may overestimate TBSA and assessment varies materially by examiner experience.nice org ukIntroduction | Mersey Burns for calculating fluid resuscitation volume when managing burns | Advice | NICEScienceDirectA comparison study of methods for estimation of a burn surface area: Lund and Browder, e-burn and Mersey BurnsPubMedEMS Burn Rule of Tens - StatPearls - NCBI Bookshelf

Treat formula-derived volumes as estimates, not proof of adequate resuscitation.

Burn shock

Start lactated Ringer resuscitation, then titrate to perfusion

Major burns require early but continuously adjusted resuscitation rather than formula-only management.Wolters KluwerFluid Resuscitation in Adult Burns : Current Medical IssuesPubMedBurn Resuscitation and Management(Archived) - StatPearls - NCBI Bookshelf

For adults with burns exceeding 20% to 25% TBSA, initiate aggressive IV fluid resuscitation to prevent burn shock. A common starting calculation is the Parkland formula: 4 mL lactated Ringer solution × body weight in kilograms × percent TBSA over the first 24 hours.PubMedBurn Resuscitation and Management(Archived) - StatPearls - NCBI BookshelfPubMedEMS Burn Rule of Tens - PubMed

Use the calculated volume as an initial guide, not a fixed prescription. Place an indwelling urinary catheter for major resuscitations and titrate fluid against urine output and serial clinical perfusion assessment. In adults, a urine output target of approximately 0.3 to 0.5 mL/kg/hour is commonly used; output below this range during the first 48 hours usually indicates inadequate resuscitation.Wolters KluwerFluid Resuscitation in Adult Burns : Current Medical Issues

Avoid treating a rising calculated requirement as an automatic indication for unlimited crystalloid. Excess fluid contributes to edema and can produce pulmonary complications; the central resuscitation principle is the minimum volume that maintains organ perfusion.Wolters KluwerFluid Resuscitation in Adult Burns : Current Medical Issuesnice org ukIntroduction | Mersey Burns for calculating fluid resuscitation volume when managing burns | Advice | NICEPubMedRule of Nines - StatPearls - NCBI Bookshelf

Expect increased requirements in patients with inhalation injury, electrical injuries, delayed resuscitation, advanced age, or greater opioid exposure, but adjust the rate to urine output and clinical response rather than applying a separate fixed multiplier.Wolters KluwerFluid Resuscitation in Adult Burns : Current Medical IssuesScienceDirectEffect of inhalation injury on fluid resuscitation requirements after thermal injury - ScienceDirect

Resuscitation failure patterns

Low urine output despite ongoing crystalloid should trigger reassessment of TBSA accuracy, elapsed time since injury, line function, concurrent hemorrhage, and inhalation or electrical injury before simply accepting a larger formula-based volume. Persistent under-resuscitation risks hypoperfusion; over-resuscitation risks respiratory and compartment complications.Wolters KluwerFluid Resuscitation in Adult Burns : Current Medical IssuesPubMedRule of Nines - StatPearls - NCBI BookshelfPubMedBurn Resuscitation and Management(Archived) - StatPearls - NCBI Bookshelf

Definitive care

Match wound depth to closure strategy and burn-center surgery

Depth and location determine whether a wound can be managed conservatively or requires operative closure planning.Wolters KluwerHistory and Advancement of Burn Treatments : Annals of Plastic Surgerynice org ukIntroduction | Mersey Burns for calculating fluid resuscitation volume when managing burns | Advice | NICE

After stabilization, characterize burn depth and reassess it serially because depth assessment drives wound-closure planning. Full-thickness burns and deep partial-thickness injuries should prompt early burn-surgeon involvement for excision and grafting strategy, especially when the area is extensive or functionally important.JAMAAdherence to Burn Center Referral Criteria for Pediatric ...Wolters KluwerHistory and Advancement of Burn Treatments : Annals of Plastic Surgery

Early excision of eschar followed by grafting is a major definitive therapy for deep burns. A randomized study cited in a historical synthesis found that early tangential excision and grafting of deep second-degree burns improved mortality and reduced hospitalization compared with conservative treatment.Wolters KluwerHistory and Advancement of Burn Treatments : Annals of Plastic Surgery

In patients with third-degree burns exceeding 30% TBSA, the mortality benefit of early excision was not uniform across subgroups in one randomized trial: benefit was reported among patients aged 17 to 30 years without inhalation injury, but not among older adults in that report. Use burn-center multidisciplinary assessment to balance operative burden, donor-site availability, inhalation injury, and physiologic reserve.Wolters KluwerHistory and Advancement of Burn Treatments : Annals of Plastic SurgeryJAMALong-term Outcome of Children Surviving Massive Burns

Longitudinal care

Monitor for complications and preserve function after survival

Long-term outcome depends on wound closure, rehabilitation planning, and ongoing multidisciplinary follow-up.JAMALong-term Outcome of Children Surviving Massive BurnsOxford Academicprogress of Chinese burn medicine from the Third Military Medical University—in memory of its pioneer, Professor Li Ao | Burns & Trauma | Oxford Academic

After acute shock and wound-closure decisions, continue surveillance for respiratory failure, burn infection, nutritional demands, wound healing problems, and scarring. Severe-burn care programs incorporate wound treatment, infection prevention and treatment, nutrition therapy, organ support, and rehabilitation because complications extend beyond the resuscitation interval.Oxford Academicprogress of Chinese burn medicine from the Third Military Medical University—in memory of its pioneer, Professor Li Ao | Burns & Trauma | Oxford Academic

For older adults, avoid nihilistic disposition decisions based on age alone. In one outcome report, standard burn treatment was associated with survival above 70%, and at least 60% of older survivors were fully functional at 6 months; individual prognosis still depends on burn extent, inhalation injury, comorbidity, and operative feasibility.JAMAOutcome for Older Burn Patients | Trauma and Injury

Use follow-up to identify hypertrophic scarring, functional limitation, and the need for reconstructive or rehabilitation interventions. Burn-care advances include rehabilitation as a core treatment domain, not an afterthought once epithelialization occurs.Oxford Academicprogress of Chinese burn medicine from the Third Military Medical University—in memory of its pioneer, Professor Li Ao | Burns & Trauma | Oxford Academic
