Apnea in the term infant

Area of Science:

• Neonatal Medicine
• Pediatric Pulmonology
• Clinical Neurology

Background:

• Apnea of prematurity is well-defined, but apnea in term infants lacks clear diagnostic criteria and standardized management.
• Distinguishing benign causes from serious underlying pathophysiology in term infants is a significant clinical challenge.

Purpose of the Study:

• To review and organize the understanding of apnea in term infants chronologically.
• To highlight the diagnostic and management dilemmas faced by healthcare providers.

Main Methods:

• Chronological organization of discussion into earlier and later postnatal periods.
• Review of presumed apnea etiologies, including physiologic, positional, feeding, and seizure-related causes.
• Characterization of later events as brief resolved unexplained events (BRUE), formerly apparent life-threatening events (ALTE).

Main Results:

• In early infancy, presumed apnea can stem from physiologic events or serious conditions like seizures.
• Beyond the neonatal period, presumed apnea is often classified as BRUE, with unidentified precipitating events.
• Healthcare providers face uncertainty regarding hospitalization and workup for these events.

Conclusions:

• Apnea in term infants requires careful evaluation to differentiate benign from severe causes.
• The classification and management of brief resolved unexplained events (BRUE) remain areas of ongoing clinical consideration.
• Standardized diagnostic criteria and management protocols for apnea in term infants are needed.
