Abstract
Objectives
To compare survival and short-term respiratory outcomes of infants weighing <750 g initially intubated with 2.0 mm versus 2.5 mm endotracheal tube (ETT).
Study design
Retrospective, observational cohort study.
Results
Of 149 inborn infants weighing <750 g admitted to the NICU, 69 (46%) were intubated with 2.0 mm ETT, 78 with 2.5 mm ETT (53%), and 2 infants never required intubation. Infants intubated with 2.0 mm ETT were more premature (median gestational age (GA) 23 weeks (22, 24) vs. 24 weeks (24, 25) p < 0.0001), smaller (median birth weight 545 g (450, 616) vs. 648 g (579, 700), p < 0.0001), and more frequently intubated at delivery (96% vs. 68%, p < 0.00001). Survival to discharge was similar 77%, 53/69 and 87%, 68/78 (p = 0.09). Adjusted for GA, there were no significant differences in ventilator days (p = 0.7338) or Grade 3 BPD.
Conclusions
Premature infants born at a median GA of 23 weeks and median birth weight of 545 g can be successfully managed with 2.0 mm ETT.
