Early versus delayed extubation in extremely preterm neonates: a retrospective cohort study

Area of Science:

• Neonatal Medicine
• Pediatric Critical Care
• Respiratory Physiology

Background:

• Extubation timing in extremely preterm neonates is critical for clinical outcomes.
• Understanding the impact of early versus delayed extubation is essential for optimizing care.

Purpose of the Study:

• To evaluate clinical outcomes associated with extubation timing in extremely preterm neonates (<26 weeks' gestational age).

Main Methods:

• Retrospective analysis of 197 neonates meeting extubation criteria within the first postnatal week.
• Classification into early extubation (≤24 hours) and delayed extubation (>24 hours) groups.
• Exclusion of infants with severe IVH or significant PDA prior to extubation criteria.

Main Results:

• No significant difference in survival without bronchopulmonary dysplasia (BPD) between early and delayed extubation groups (aOR 1.26; P=0.52).
• No significant difference in survival without severe intraventricular hemorrhage (IVH) between groups (aOR 1.98; P=0.08).
• Results were adjusted for gestational age, SNAP score, surfactant doses, and study center.

Conclusions:

• Extubation within 24 hours of meeting criteria was not associated with improved survival without BPD or severe IVH in extremely preterm neonates.
• Confounding by indication is a limitation, suggesting the need for prospective trials to definitively assess extubation timing effects.
