해설
Gentle tactile stimulation is the first-line intervention for apnea of prematurity as it effectively stimulates breathing without invasive procedures. Other options are used if stimulation fails or for specific indications.
Understanding Apnea of Prematurity
Apnea of prematurity is a common condition in infants born before 37 weeks gestation, resulting from an immature central nervous system and respiratory control centers in the brainstem. In a preterm newborn at 32 weeks, the respiratory drive is underdeveloped, leading to periodic pauses in breathing lasting more than 20 seconds, often accompanied by bradycardia and desaturation. The immediate goal of nursing intervention is to restart breathing using the least invasive method possible.
Rationale for the First Action: Tactile Stimulation
The first-line intervention for an apneic episode in a preterm infant is gentle tactile stimulation. The 2025 Korean Guidelines for Cardiopulmonary Resuscitation emphasize a stepwise approach to neonatal resuscitation, where stimulation is a fundamental initial step to trigger spontaneous respiratory effort . A multicentre neonatal manikin study highlighted that tactile stimulation is a prompt intervention used to prevent long-term adverse outcomes, though it also noted a large heterogeneity in how stimulation is performed across different settings [2]. Common techniques include rubbing the infant’s back or flicking the soles of the feet. This mechanical stimulus activates peripheral sensory receptors, which send afferent signals to the reticular activating system in the brainstem, effectively "waking up" the respiratory center and prompting the infant to resume breathing. It is non-invasive, immediately available, and often resolves the apnea without further escalation.
Why Other Options Are Not the First Step
- Administer supplemental oxygen via nasal cannula: While hypoxia may accompany apnea, applying oxygen alone does not address the central cause of the pause—the lack of respiratory effort. The infant must first be stimulated to breathe; otherwise, oxygen cannot be effectively delivered to the alveoli. Guidelines recommend tactile stimulation before initiating positive pressure ventilation or supplemental oxygen .
- Position the infant in prone position: Prone positioning can improve thoracoabdominal synchrony and lung volumes in preterm infants, but it is a supportive, not a rescue, measure during an active apneic spell. Positioning adjustments are part of ongoing care, not the immediate response to an acute cessation of breathing.
- Prepare for immediate intubation and mechanical ventilation: Intubation is an invasive procedure reserved for infants who do not respond to initial resuscitation steps, including stimulation and bag-mask ventilation. The 2025 Korean Guidelines recommend escalating to positive pressure ventilation only if the heart rate remains below 100 bpm after initial steps . Jumping directly to intubation bypasses effective, less invasive interventions.
Clinical Correlation with Pharmacological Management
If apnea of prematurity is recurrent and not solely responsive to stimulation, pharmacological management becomes central. Methylxanthines, such as caffeine citrate, are the first-line medication for apnea of prematurity . Caffeine acts as a central nervous system stimulant by antagonizing adenosine receptors, thereby increasing the sensitivity of the respiratory center to carbon dioxide and enhancing diaphragmatic contractility. A prospective observational study on caffeine therapy noted that serum concentrations of caffeine exhibit marked variability due to immature hepatic metabolism and drug-drug interactions, underscoring the importance of therapeutic drug monitoring to prevent complications from overaccumulation, such as tachycardia and feeding intolerance . Serum titers above 50 μg/mL are considered high and require close monitoring . This pharmacological support works in tandem with nursing interventions; tactile stimulation manages acute episodes, while caffeine reduces their frequency and severity.

Clinical Practice Guide: Managing Apnea of Prematurity
Scenario: A 32-week gestation preterm infant in the NICU experiences an apneic episode with bradycardia and desaturation.
Stepwise Nursing Intervention
Immediate Response: Gentle Tactile Stimulation
Rub the infant’s back or flick the soles of the feet for 10-15 seconds.
Avoid vigorous or painful stimulation, which can cause injury or increased stress.
Rationale: This activates peripheral sensory receptors, signaling the brainstem to resume respiratory effort.
Evaluate Response
If breathing resumes and heart rate is above 100 bpm, continue close monitoring.
If apnea, bradycardia, or desaturation persists, proceed to the next step.
Airway and Ventilation Support
Open the airway using a neutral head position (sniffing position).
Initiate positive pressure ventilation (PPV) with a bag and mask if heart rate drops below 100 bpm despite stimulation.
Administer supplemental oxygen as needed to maintain target saturations (typically 90-95% for preterm infants).
Advanced Resuscitation
If PPV is ineffective and heart rate remains below 60 bpm, prepare for intubation and mechanical ventilation.
Initiate chest compressions and administer emergency medications (e.g., epinephrine) per NRP guidelines.
Key Clinical Pearls
Least Invasive First: Always start with the simplest, least traumatic intervention. Tactile stimulation is effective for most self-resolving apneic spells.
Monitor for Triggers: Assess for underlying causes such as sepsis, hypoglycemia, or temperature instability if apnea is recurrent.
Parent Education: Teach caregivers about the benign nature of apnea of prematurity and the rationale for stimulation, reducing anxiety.
Apnea of Prematurity — Cessation of breathing lasting 20 seconds or longer, or shorter if accompanied by bradycardia/oxygen desaturation, occurring in premature infants with a gestational age of less than 37 weeks. The primary cause is immaturity of the central nervous system.
Bradycardia — A condition where the heart rate drops below the normal range for the person's age. In premature infant apnea, a heart rate dropping below 100 beats per minute is an important sign.
Tactile Stimulation — Non-invasive intervention that induces a physiological response (resumption of breathing) through gentle tactile input (rubbing, light tapping). First-line treatment for apnea of prematurity.
Oxygen Desaturation — A phenomenon where blood oxygen saturation (SpO2) falls below the normal range. One of the key signs to monitor during apnea in premature infants.
Bag-Mask Ventilation — A method of manually assisting a patient's breathing by applying positive pressure using a bag-valve mask. The next step intervention in cases of apnea where the patient does not respond to tactile stimulation.
