Burn injury

The nurse is conducting an initial assessment of a pediatric burn patient in the emergency department.

2 Second-degree burns on both arms with intact blisters

해설

Stridor and hoarse voice with singed nasal hairs indicate potential inhalation injury and airway compromise, which is the most life-threatening complication requiring immediate intervention. Other findings like burns, tachycardia, or crying are concerning but not immediately life-threatening.

Initial Assessment of a Pediatric Burn Patient

When a toddler presents with burns sustained in a house fire, the immediate priority is to assess the airway and breathing. Inhalation injury is a leading cause of early mortality in burn patients, and its signs can be subtle initially but progress rapidly. The finding of stridor and a hoarse voice with singed nasal hairs indicates a direct thermal injury to the upper airway, which is the most concerning finding requiring immediate intervention.

The pathophysiology involves direct thermal damage to the oropharyngeal and laryngeal mucosa. This triggers a massive inflammatory response, leading to rapid capillary leak and the development of significant edema in the loose tissues of the supraglottic structures. As described in the literature on laryngeal thermal burns, even in a patient with initially stable vital signs, "marked supraglottic edema" can develop, posing a "risk of delayed airway obstruction" ^[2]. The stridor is a high-pitched sound generated by turbulent airflow through a critically narrowed airway, signaling that the edema is already compromising the lumen. A hoarse voice specifically points to glottic and vocal cord involvement. This situation can deteriorate swiftly, and the airway can become completely obstructed. A parallel can be drawn to the mechanism of airway obstruction from a fibrinous pseudomembrane, where a "valvular obstruction that blocks airway ventilation" leads to "obvious dyspnea" and acute respiratory failure . While the etiology differs, the consequence of a physical barrier in an already edematous airway is the same: a life-threatening loss of the patent airway. Therefore, immediate preparation for endotracheal intubation is the critical intervention.

The other options, while requiring assessment and management, do not represent an immediate threat to the airway.

- Option 2: Second-degree burns on both arms with intact blisters are a significant injury covering a large surface area, which will require fluid resuscitation and meticulous wound care. However, they do not pose an immediate threat to the airway or breathing. The blisters being intact is actually a positive finding, as it provides a natural barrier against infection.
- Option 3: A heart rate of 140 beats per minute is tachycardic for a 2-year-old. In the context of a major burn, this is an expected physiological response driven by pain, anxiety, and the initiation of a systemic inflammatory response with fluid shifts. While it requires monitoring and is a component of shock assessment, it is not the most immediately life-threatening finding when compared to a compromised airway.
- Option 4: Crying and asking for parents is a developmentally appropriate and positive neurological sign for a 2-year-old. It indicates a patent airway, adequate oxygenation for vocalization, and an intact level of consciousness. This behavior is reassuring and does not warrant an immediate intervention beyond providing comfort and facilitating family presence.
