## 문제

A 3-year-old child is brought to the emergency department by parents who suspect the child ingested household cleaning products 2 hours ago. Which assessment finding would be the MOST concerning and require immediate intervention?

## 보기

1. Mild nausea and one episode of vomiting
2. Restlessness and crying when separated from parents
3. Drooling, difficulty swallowing, and refusal to drink fluids **✔ 정답**
4. Slight abdominal tenderness on palpation

**정답: 3**

## 해설

Drooling, difficulty swallowing, and refusal to drink fluids indicate oropharyngeal/esophageal burns from caustic ingestion, requiring immediate airway assessment and intervention. Other options represent milder symptoms manageable with standard care.

Clinical Reasoning & Corrosive Ingestion Triage

When a child presents with suspected corrosive substance ingestion, the immediate nursing priority is to identify signs of airway compromise or significant esophageal injury. The assessment findings must be rapidly differentiated to determine which symptom cluster indicates a life-threatening or organ-threatening emergency.

Analysis of Assessment Findings

The correct answer is 3 because drooling, difficulty swallowing, and refusal to drink fluids are the classic clinical triad indicating significant esophageal injury or obstruction. This presentation strongly suggests the presence of a deep caustic burn, edema, and potential impending perforation. The inability to manage oral secretions (drooling) is a critical sign that the esophagus may be functionally or mechanically obstructed, placing the child at high risk for aspiration and respiratory distress. According to the algorithm proposed by Ateş et al., the presence of hypersalivation and dysphagia is a key indicator for performing urgent endoscopy, as these symptoms correlate with more severe mucosal damage [1]. This finding requires immediate intervention to secure the airway and prepare for diagnostic endoscopy.

The other options represent expected or less critical findings in this scenario:

- 1. Mild nausea and one episode of vomiting: While vomiting can occur after ingestion, it is a non-specific symptom and does not independently signal severe transmural necrosis or airway threat. However, the nurse must monitor for hematemesis, which would escalate concern.

- 2. Restlessness and crying when separated from parents: This is an age-appropriate developmental response (separation anxiety) for a 3-year-old in a stressful emergency department environment. It does not reflect the physiological severity of the ingestion.

- 4. Slight abdominal tenderness on palpation: Mild tenderness may be present due to gastric irritation. However, severe epigastric pain, rigidity, or rebound tenderness would be more concerning for perforation or peritonitis. Slight tenderness alone does not demand the same immediate, life-saving intervention as an inability to handle secretions.

Pathophysiology & Clinical Correlation

Corrosive substances cause liquefactive (alkali) or coagulative (acid) necrosis upon contact with the oropharyngeal and esophageal mucosa. The resulting inflammation leads to edema, ulceration, and in severe cases, full-thickness necrosis . The clinical spectrum varies widely, but the anatomical location of the injury is critical; esophageal impaction or severe circumferential burns lead to the symptoms described in option 3. The refusal to drink is a behavioral response to odynophagia (painful swallowing), while drooling results from an inability to swallow saliva past the injured, edematous segment. This presentation is a hallmark of a potentially severe injury that can rapidly progress to stricture formation or perforation if not managed promptly . The management principles for caustic ingestion emphasize that the presence of these specific symptoms should trigger a higher level of care and specialist consultation, as they guide the decision-making for airway management and the timing of endoscopic evaluation [1].References (research sources)

Pediatric Corrosive Ingestion TriageIdentifying the Critical Airway Threat
In suspected corrosive ingestion, the clinical triad of drooling, dysphagia, and refusal to drink indicates significant esophageal injury or obstruction.

This presentation suggests deep caustic burns and edema, placing the child at high risk for aspiration and esophageal perforation. Immediate airway protection is the priority.

CautionNever induce vomiting or attempt to neutralize the substance. The inability to manage oral secretions is a key indicator for urgent endoscopy and potential ICU admission.

## 핵심 개념

- **Corrosive Ingestion** — Swallowing of acidic or alkaline substances causing chemical burns to the oropharynx, esophagus, and stomach.
- **Dysphagia** — Difficulty swallowing, often indicating esophageal edema, obstruction, or severe mucosal injury.
- **Hypersalivation (Drooling)** — Inability to manage oral secretions due to pain or obstruction, a critical sign of esophageal injury.
- **Esophageal Perforation** — A full-thickness tear in the esophageal wall, a life-threatening complication of deep caustic burns.
- **Triage** — The process of determining the priority of patients' treatments based on the severity of their condition.
