A 45-year-old industrial worker is rapidly brought to the emergency department after being trapped in a structural fire. On arrival, he has obvious soot in his oropharynx, marked hoarseness, and inspiratory stridor. Physical examination reveals deep, leathery, charred skin completely encircling his anterior and posterior thorax. His respiratory rate is 34/min, and he is demonstrating poor breathing efforts with minimal chest wall expansion. Oxygen saturation is 86% on a high-flow oxygen mask. Blood pressure is 98/60 mm Hg, and pulse is 128/min. Arrange the following interventions in the most appropriate chronological sequence based on prioritized trauma and burn life support principles.
- 1Perform endotracheal intubation
- 2Perform bedside chest escharotomies
- 3Initiate intravenous lactated Ringer solution
- 4Insert a urinary catheter
- 5Perform early burn excision and skin grafting
Cevap
The correct sequence is: Endotracheal intubation, followed by chest escharotomies, then initiation of intravenous fluids, followed by urinary catheter insertion, and finally early excision and skin grafting.
The standard trauma and burn algorithms dictate a strict ABC sequence: Airway, Breathing, Circulation. In this patient, signs of inhalation injury (stridor, soot) mandate immediate intubation (Airway). However, because of the circumferential full-thickness chest burn, the chest wall cannot adequately expand; therefore, positive pressure ventilation will be ineffective until chest escharotomies are performed (Breathing). Once ventilation is established, fluid resuscitation (Circulation) using crystalloids is initiated. A urinary catheter is placed subsequently to monitor the adequacy of resuscitation. Definitive operative management with excision and grafting occurs during the delayed hospital course.

Anahtar Kavram
Advanced Trauma Life Support (ATLS) and Advanced Burn Life Support (ABLS) algorithms strictly prioritize Airway, Breathing, and Circulation sequentially, adapting interventions like escharotomy to support the 'Breathing' component.
