Cardiorespiratory events with bolus versus continuous enteral feeding in healthy preterm infants

Area of Science:

• Neonatology
• Pediatric Gastroenterology
• Respiratory Physiology

Background:

• Preterm infants often require nutritional support via tube feeding.
• Cardiorespiratory events, such as apnea, are common in preterm infants.
• The method of tube feeding (bolus vs. continuous) may influence cardiorespiratory stability.

Purpose of the Study:

• To compare the incidence of cardiorespiratory events between bolus and continuous tube feeding in healthy preterm infants.
• To assess the impact of feeding modality on apnea and hypoxia in neonates.

Main Methods:

• Polysomnographic monitoring was employed to detect cardiorespiratory events.
• Healthy preterm infants were divided into groups receiving either bolus or continuous tube feeding.
• Apnea and apnea-related hypoxic episodes were quantified and compared between groups.

Main Results:

• Continuous tube feeding was associated with a significant increase in the frequency of apneas.
• Apneas during continuous tube feeding led to a higher number of hypoxic episodes.
• Bolus tube feeding demonstrated a comparatively lower incidence of cardiorespiratory disturbances.

Conclusions:

• Continuous tube feeding may pose a higher risk for cardiorespiratory events, including apnea and hypoxia, in preterm infants.
• Bolus tube feeding appears to be a safer alternative regarding cardiorespiratory stability in this population.
• Further research is warranted to optimize feeding strategies for preterm neonates to minimize cardiorespiratory compromise.
