Impact of early extubation and reintubation on the incidence of bronchopulmonary dysplasia in neonates.

OBJECTIVE

The objective of this study was to assess rates of bronchopulmonary dysplasia (BPD) and BPD/death in infants first extubated between day of life (DOL) 1 to 3 versus 4 to 7, 8+, and impact of reintubation.

STUDY

DESIGN

We included infants with gestational age ≤ 28 weeks, birth weight ≤ 1,000 g, and intubation on DOL 1. Proportional hazards regression modeled time to BPD and BPD/death, adjusting for potential confounders.

RESULTS

Of 262 infants, 101 (38.55%), 41 (15.65%), and 120 (45.80%) were extubated between DOL 1 to 3, 4 to 7, and 8+, respectively. Extubation between DOL 4 to 7 and DOL 1 to 3 was associated with an increased hazard of developing BPD (hazard ratio [HR], 1.7; 95% confidence interval [CI], 1.0-2.8; p < 0.05). Extubation on DOL 8+ was associated with a significantly increased hazard compared with extubation between DOL 1 to 3 (HR, 16.9; 95% CI, 10.5-27.1; p < 0.0001) and DOL 4 to 7 (HR, 10.0; 95% CI, 6.1-16.3; p < 0.0001). Similar results were noted with BPD/death. Reintubation did not affect BPD and BPD/death.

CONCLUSIONS

Delaying extubation beyond the first 3 and 7 days was associated with an increased risk of BPD and BPD/death. Reintubation did not impact outcomes.
