A preterm newborn at 30 weeks gestation is experiencing frequent apneic episodes. Which nursing intervention should be the priority?

## 보기

1. Administer supplemental oxygen via nasal cannula
2. Position the infant in prone position to improve breathing
3. Provide gentle tactile stimulation to stimulate breathing **✔ 정답**
4. Increase the ambient temperature in the incubator

**정답: 3**

## 해설

Gentle tactile stimulation is the priority for apneic episodes as it safely restores breathing. Other interventions are secondary or inappropriate for immediate response.

Correct Answer: 3. Provide gentle tactile stimulation to stimulate breathing

Understanding Apnea of Prematurity

Apnea of prematurity is a common condition in infants born before 37 weeks gestation, with a higher incidence in those born at 30 weeks or less. It occurs due to an immature central nervous system, which fails to properly regulate the respiratory drive. This results in a pause in breathing for more than 20 seconds, or a shorter pause accompanied by bradycardia or desaturation. The immediate goal during an apneic episode is to restart breathing to prevent hypoxia and its long-term adverse outcomes [2].

Why Tactile Stimulation is the Priority Intervention

When an apneic episode occurs, the nurse's first and most critical action is to provide gentle tactile stimulation. This is a non-invasive, immediate intervention that directly addresses the lack of respiratory effort. The mechanism involves activating the peripheral nervous system, which sends a wake-up signal to the brainstem's respiratory centers, prompting the infant to resume spontaneous breathing. A recent multicentre neonatal manikin study highlighted that tactile stimulation is a standard, prompt intervention for apnea of prematurity, although it noted a wide variation in the specific techniques used [2]. The priority is to act quickly, and stimulation is the most direct method to end the apneic spell.

Analyzing the Other Options

- Option 1: Administer supplemental oxygen via nasal cannula. While maintaining adequate oxygenation is crucial, simply applying oxygen does not address the primary problem, which is the cessation of breathing. If the infant is not breathing, oxygen cannot reach the lungs or bloodstream effectively. This intervention would be appropriate after breathing has been re-established, if the infant remains hypoxic despite a patent airway and spontaneous respirations.

- Option 2: Position the infant in prone position to improve breathing. The prone position can improve thoracoabdominal synchrony and oxygenation in some preterm infants during stable periods. However, positioning is a preventive or supportive measure, not an emergency intervention during an active apneic spell. Changing an infant's position during an apneic event delays the immediate stimulation needed to restart breathing. Furthermore, the prone position is only recommended for hospitalized, continuously monitored infants due to its association with an increased risk of sudden infant death syndrome (SIDS).

- Option 4: Increase the ambient temperature in the incubator. Maintaining a neutral thermal environment is a fundamental part of supportive care for preterm infants, as cold stress can increase metabolic demands and potentially contribute to apnea. However, adjusting the incubator temperature is a slow, environmental intervention. It will not provide the immediate stimulus required to terminate an ongoing apneic episode, making it a lower priority than a direct intervention like tactile stimulation.

Connecting to Pharmacological Management

While tactile stimulation is the first-line nursing intervention for an acute episode, it is important to understand its place within the broader management of apnea of prematurity. For recurrent or severe apnea, pharmacological therapy with methylxanthines like caffeine citrate is the standard of care. Caffeine works by stimulating the central nervous system and increasing the sensitivity of the respiratory centers to carbon dioxide, thereby reducing the frequency of apneic episodes. A prospective observational study confirms that methylxanthines are the first-line medication for this condition . However, this study also underscores the complexity of this therapy, noting that serum concentrations can vary significantly due to immature hepatic metabolism and drug interactions, which makes therapeutic drug monitoring essential to prevent complications from drug accumulation . This pharmacological approach is a long-term management strategy, not an emergency response to a single apneic event, reinforcing why immediate tactile stimulation takes priority at the bedside [1,2].References (research sources)

## 임상 시나리오

Clinical Practice Guide: Apnea of Prematurity

For a preterm newborn at 30 weeks gestation experiencing an apneic episode, the immediate nursing priority is to restart spontaneous breathing. The following steps outline the rapid response sequence.

Priority Intervention

- **Gentle Tactile Stimulation:** Flick the soles of the feet or rub the infant's back. This peripheral stimulus activates the brainstem respiratory centers. This is the first-line action to terminate an apneic spell.

Subsequent Actions if Apnea Persists

- **Airway and Breathing Support:** If stimulation fails, initiate positive pressure ventilation (PPV) with a bag and mask using room air, titrating oxygen only as needed per pulse oximetry to avoid retinopathy of prematurity.

- **Pharmacological Management:** Caffeine citrate is the standard maintenance therapy to reduce the frequency of apneic episodes. Administer as prescribed, typically as a loading dose followed by daily maintenance.

- **Non-Invasive Respiratory Support:** Nasal continuous positive airway pressure (NCPAP) or high-flow nasal cannula may be used to stent the airway open and prevent episodes.

Key Safety Considerations

- **Positioning:** Always place the infant in a supine position for sleep to reduce the risk of Sudden Infant Death Syndrome (SIDS). Prone positioning is not recommended for routine care.

- **Thermoregulation:** Maintain a neutral thermal environment using a servo-controlled incubator to minimize metabolic oxygen demand, but this is a supportive, not acute rescue, measure.

- **Monitoring:** Continuous cardiorespiratory monitoring and pulse oximetry are essential to promptly detect bradycardia and desaturation associated with apneic events.

## 핵심 개념

- **Apnea of Prematurity** — A pause in breathing for more than 20 seconds, or a shorter pause with bradycardia or desaturation, caused by an immature central nervous system in infants born before 37 weeks gestation.
- **Tactile Stimulation** — A non-invasive intervention involving gentle touch to activate the peripheral nervous system, signaling the brainstem to resume spontaneous respiratory effort.
