A 2-year-old toddler is brought to the emergency department by parents who report that the child was playing with small toys and suddenly began coughing violently, then became unable to speak or cry. The child is now sitting upright, leaning forward, with stridor and cyanosis around the lips. What is the most appropriate immediate nursing intervention?

Emergency management of suspected foreign body aspiration in a pediatric patient

## 보기

1. Position the child supine and perform blind finger sweeps to remove the object
2. Immediately begin chest compressions and rescue breathing
3. Allow the child to remain in a position of comfort while preparing for emergency bronchoscopy
4. Perform the Heimlich maneuver (abdominal thrusts) immediately **✔ 정답**

**정답: 4**

## 해설

For a child with signs of severe partial airway obstruction (unable to speak/cry, cyanosis), immediate Heimlich maneuver is indicated to prevent progression to complete obstruction. Other options are inappropriate: blind sweeps risk pushing the object deeper, CPR is for unresponsive patients, and waiting for bronchoscopy delays life-saving intervention.

Clinical Scenario Analysis

This toddler presents with a classic triad of sudden-onset severe coughing, aphonia (inability to speak or cry), and stridor with cyanosis, following play with small toys. The child is conscious, sitting upright, and leaning forward in a tripod position. This presentation indicates a severe, life-threatening foreign body airway obstruction (FBAO). The leaning-forward posture is a spontaneous attempt to maximize airway diameter. The presence of cyanosis signals critical hypoxemia, and the inability to vocalize confirms a near-complete or complete airway blockage. Immediate action to relieve the obstruction is required to prevent cardiac arrest.

Why the Correct Answer Is the Immediate Priority

The correct intervention is to perform the Heimlich maneuver (abdominal thrusts) immediately.

For a child older than 1 year of age with a severe airway obstruction who is still conscious, the 2025 Korean Guidelines for Cardiopulmonary Resuscitation and international standards dictate the immediate delivery of abdominal thrusts [4]. This technique creates an artificial cough by generating a sudden increase in intrathoracic pressure, which can forcefully expel the foreign body from the airway. In this scenario, the child’s condition—conscious but with ineffective cough, stridor, and cyanosis—is the precise indication for this life-saving maneuver. Delaying this intervention to prepare for other procedures risks rapid deterioration to unconsciousness and cardiac arrest, which, in pediatric patients, is most often a secondary event resulting from progressive asphyxia [4].

Analysis of Incorrect Options

Option 1: Position the child supine and perform blind finger sweeps to remove the object.

This action is contraindicated. Performing a blind finger sweep in a child can push the foreign body deeper into the airway, converting a partial obstruction into a complete one, or cause trauma to the oropharynx. A finger sweep should only be performed if the object is clearly visualized in the mouth.

Option 2: Immediately begin chest compressions and rescue breathing.

This is incorrect because the child is still conscious. Chest compressions are initiated only when a patient with an airway obstruction becomes unresponsive and has no pulse. Furthermore, attempting rescue breaths without first clearing the obstruction is futile, as air cannot pass the blockage.

Option 3: Allow the child to remain in a position of comfort while preparing for emergency bronchoscopy.

While definitive management often requires rigid bronchoscopy for foreign body removal, this is not the most appropriate immediate nursing intervention for a conscious patient with a complete or near-complete obstruction and cyanosis [1,2]. The priority is to relieve the life-threatening obstruction at the bedside without delay. Preparation for bronchoscopy is a secondary action that should occur simultaneously with, but not instead of, immediate efforts to dislodge the object. Delaying to prepare for a procedure while the child is actively asphyxiating is a critical error. The guideline emphasizes prompt intervention and stabilization when definitive bronchoscopy is not immediately available .

Pathophysiology and Clinical Reasoning

Children aged 1 to 3 years are at the highest risk for foreign body aspiration due to immature swallowing reflexes, a propensity for oral exploration, and incomplete dentition that limits their ability to properly grind food . The aspirated object can lodge in the larynx or trachea, causing a severe obstruction. The pathophysiological cascade begins with acute hypoxemia from impaired ventilation. If unrelieved, this progresses to acute hypercapnic respiratory failure, a rare but severe complication where carbon dioxide accumulates to dangerous levels . The initial sympathetic response causes tachycardia and hypertension, but as hypoxia and acidosis worsen, myocardial function deteriorates, leading to bradycardia, the most common terminal rhythm in pediatric asphyxial arrest [4]. The presence of cyanosis in this toddler indicates that the oxygen saturation is critically low, likely below 85%, and cardiorespiratory collapse is imminent without immediate reversal of the airway obstruction.References (research sources)

## 임상 시나리오

Pediatric Choking: Conscious Child Over 1 YearImmediate Response to Severe Airway Obstruction
For a conscious child older than 1 year with a severe foreign body airway obstruction, indicated by ineffective cough, aphonia, or cyanosis, perform abdominal thrusts (Heimlich maneuver) without delay.

Stand or kneel behind the child. Place a fist with the thumb side against the child's abdomen, just above the umbilicus and well below the xiphoid process. Grasp your fist with the other hand and deliver quick, inward and upward thrusts.

Continue thrusts until the object is expelled or the child becomes unresponsive. If unresponsiveness occurs, immediately begin CPR, starting with chest compressions, and look for the object in the mouth before giving breaths.

CautionNever perform blind finger sweeps on a child, as this can push the foreign body deeper into the airway. Do not delay intervention to call for help first; if alone, perform 5 cycles of back blows/chest thrusts (for infants) or abdominal thrusts (for children) before calling emergency services.

## 핵심 개념

- **Foreign Body Airway Obstruction (FBAO)** — A life-threatening emergency where an object blocks the airway, preventing normal breathing; requires immediate intervention to prevent hypoxic cardiac arrest.
- **Heimlich Maneuver (Abdominal Thrusts)** — A first-aid procedure for conscious choking victims over 1 year old, using upward abdominal thrusts to create artificial cough and expel a foreign body.
- **Stridor** — A high-pitched, harsh sound heard during inspiration, indicating a partial obstruction of the upper airway, commonly seen in croup or foreign body aspiration.
- **Aphonia** — The inability to produce voiced sound or speak, a critical sign of complete or near-complete airway obstruction in a choking victim.
- **Tripod Position** — A sitting posture where the patient leans forward with arms braced on their knees, a spontaneous sign of severe respiratory distress to maximize airway patency.
