We examined the association between the number of tracheal intubation (TI) attempts and clinical outcomes in extremely preterm infants.
This is a single-center retrospective cohort study examining infants born at ≤28 weeks gestation intubated within the first four postnatal days. We analyzed infant, provider, and practice characteristics and clinical outcomes by exposure groups (1 vs. 2 vs. ≥3 TI attempts). Primary outcomes were death prior to NICU discharge or severe intraventricular hemorrhage (IVH).
Ninety-nine infants were included. 46.5% required one TI attempt, 29.3% required two, and 24.2% required three or more. Increasing attempts was significantly associated with death (p = 0.004), adverse tracheal intubation-associated events (TIAEs; p = 0.004), and the training level of the first attempt provider (p = 0.002). No association was found with severe IVH or complications of prematurity.
Increasing attempts was associated with death and adverse TIAEs. Careful selection of providers could decrease adverse TIAEs and improve outcomes.
