## 문제

A 4-year-old child is brought to the emergency department with burns covering 18% of the total body surface area (TBSA) from a house fire. The burns involve the chest, abdomen, and both arms. What is the most critical assessment finding that would indicate the need for immediate intervention?

## 보기

1. Presence of blisters on the chest and abdomen
2. Hoarse voice and difficulty swallowing **✔ 정답**
3. Pain level of 8/10 on the pediatric pain scale
4. Decreased urine output of 0.8 mL/kg/hr

**정답: 2**

## 해설

Hoarse voice and difficulty swallowing indicate inhalation injury and airway compromise, requiring immediate intervention to prevent airway obstruction in pediatric burn patients. Other findings like blisters, pain, or decreased urine output are important but less critical than airway issues.

Priority Assessment for a Child with Face and Neck Burns

The correct answer is Airway patency and respiratory status.

In the initial management of any burn patient, the primary survey always begins with Airway, Breathing, and Circulation (ABCs). For this child, the anatomical location of the burns—the face, neck, and upper chest—makes airway compromise an immediate and life-threatening risk. The pathophysiological rationale is that burns to the face and neck are in close proximity to the airway, which strongly predisposes the patient to inhalation injury and subsequent airway edema [1]. The clinical evidence supporting this is stark: a cohort study found that patients with facial and neck burns had a dramatically higher incidence of inhalation injury (34.8%) compared to those without such burns (2.8%) [1]. This thermal and chemical damage to the respiratory tract can lead to rapid, unpredictable swelling of the upper airway, especially in a young child whose airway anatomy is already smaller and more easily obstructed.

This assessment priority is further reinforced by the critical nature of the intervention that often follows. The same study demonstrated that the presence of facial and neck burns necessitated endotracheal intubation in 51.9% of cases, a rate nearly four times higher than in patients without these injuries (14.1%) [1]. This statistic underscores why the nurse must immediately assess for signs of stridor, hoarseness, singed nasal hairs, carbonaceous sputum, and increased work of breathing. A delay in recognizing a deteriorating airway can lead to a difficult intubation scenario, a high-acuity, low-frequency event made even more challenging in pediatric patients with airway edema from inhalational injuries [3]. While flexible bronchoscopy is considered the gold standard for diagnosing the severity of an inhalation injury, the bedside nurse's clinical assessment of airway patency is the crucial first step that triggers the need for such advanced diagnostics and life-saving interventions [2].

Although the other options represent important aspects of burn care, they are secondary to securing the airway. Monitoring fluid balance through urine output (Option 2) addresses circulation, which is the third step in the ABCs. Assessing pain (Option 1) and determining burn depth and extent (Option 4) are vital components of the secondary survey, which is performed only after the primary survey is complete and life-threatening conditions are addressed. The immediate risk of respiratory failure from a compromised airway always takes precedence.References (research sources)

Clinical Practice Guide: Pediatric Burn with Suspected Inhalation Injury

Immediate Airway Assessment

For any pediatric burn sustained in an enclosed space, assume inhalation injury until proven otherwise. The highest priority is a rapid airway assessment. Look for early signs of supraglottic edema: hoarseness, stridor, difficulty swallowing, drooling, or a brassy cough. These findings demand immediate preparation for endotracheal intubation, as a child's narrow airway can obstruct completely within hours. Delay in securing the airway is the most common critical error in these cases.

Fluid Resuscitation and Monitoring

After the airway is secured, initiate fluid resuscitation using the Parkland formula for burns over 15% TBSA. The goal for pediatric patients is a urine output of 1.0-1.5 mL/kg/hr. A rate of 0.8 mL/kg/hr, while slightly low, does not take priority over a threatened airway. Accurate hourly monitoring is essential to avoid under-resuscitation or fluid overload, which can worsen pulmonary edema in the presence of an inhalation injury.

Pain and Wound Management

Pain from partial-thickness burns is severe and requires intravenous opioid analgesia. However, administer analgesics only after the airway and hemodynamic status are stable, as respiratory depression is a significant risk. Cover burns with dry, sterile sheets to minimize contamination and pain; do not apply ice or ointments. Blister management is a secondary concern for the burn center and should not delay transport or definitive airway care.

## 핵심 개념

- **Inhalation Injury** — Damage to the respiratory tract caused by inhaling superheated air, steam, or toxic chemicals, commonly seen in enclosed-space fires and indicated by signs like hoarseness or carbonaceous sputum.
- **Supraglottic Airway Edema** — Swelling of structures above the vocal cords, a rapid and life-threatening consequence of thermal injury that can quickly obstruct the narrow pediatric airway.
- **ABC Priority Framework** — A systematic approach in emergency care that prioritizes Airway, Breathing, and Circulation in that order to address the most immediately life-threatening conditions first.
