A 40-year-old man is brought to the emergency department after being rescued from a house fire. He has full-thickness burns involving his entire anterior chest, abdomen, and both upper extremities (approximately 36% total body surface area). He is awake but agitated. On primary survey, he has singed nasal hairs, a hoarse voice, and carbonaceous sputum. Vital signs are temperature 37.0°C (98.6°F), blood pressure 110/70 mmHg, heart rate 115/min, and respiratory rate 24/min. Arrange the following management steps in the optimal chronological order according to standard Advanced Trauma Life Support (ATLS) and burn protocols.
- 1Endotracheal intubation
- 2Placement of large-bore peripheral intravenous lines and initiation of crystalloid fluid resuscitation
- 3Insertion of an indwelling urinary catheter to monitor output
- 4Cleansing of burn wounds and application of topical antimicrobial dressings
- 5Tangential excision of the burn eschar and split-thickness skin grafting
Answer
The correct order is: Endotracheal intubation -> Placement of large-bore peripheral intravenous lines and initiation of crystalloid fluid resuscitation -> Insertion of an indwelling urinary catheter to monitor output -> Cleansing of burn wounds and application of topical antimicrobial dressings -> Tangential excision of the burn eschar and split-thickness skin grafting.
The correct sequence strictly adheres to the Advanced Trauma Life Support (ATLS) protocol. The primary survey always prioritizes the airway (A). This patient has clear clinical indicators of inhalation injury (singed nasal hairs, hoarseness, carbonaceous sputum), which carries a high risk of rapid airway obstruction from edema; thus, endotracheal intubation is the immediate first step. Next, circulation (C) must be supported. Severe burns cause massive fluid shifts, requiring large-bore intravenous access and aggressive crystalloid fluid resuscitation. Once resuscitation is initiated, adjuncts to the primary survey are placed, notably an indwelling urinary catheter, to monitor urine output and titrate fluid administration. After the patient is hemodynamically stable and the primary and secondary surveys are complete, initial wound care is performed, consisting of cleansing and applying topical antimicrobial dressings to prevent sepsis. Finally, the definitive surgical management for full-thickness burns is tangential excision and skin grafting, which is typically scheduled within the first week after injury.
Step-by-Step Solution
Key Concept
The chronological management of severe burns prioritizes securing the airway (especially with signs of inhalation injury), followed by fluid resuscitation, monitoring adjuncts, local wound care, and ultimately definitive surgical excision.
