Background: Ideal respiratory support for very low birth weight infants (VLBW) can be selected based on demographic and clinical status at birth.

Methods: In this prospective cohort study, we included 163 VLBW neonates treated with either invasive or non-invasive respiratory support in their first 72 hours of life in the neonatal intensive care unit of Mahdiyeh hospital, Tehran, Iran. We used descriptive statistics to describe the data, and multiple logistic regression to determine the factors associated with the success rate of different strategies and the choice of strategy for primary respiratory support. All analyses were done using SPSS version 20 and STATA version 12 at a significance level of 0.05.

Results: The success rates of initial respiratory supports with nasal continuous positive airway pressure (NCPAP), noninvasive positive pressure ventilation (NIPPV), and INSURE (intubation surfactant extubation) were 63.20%, 42.10% and 61.90%, respectively. The results of multiple logistic regression analysis showed patent arterial duct (PDA) (yes vs. no: OR = 0.42) had a significant effect on initial respiratory support success (P<0.05). Also, gestational age (>28 vs. ≤28 weeks: OR = 0.26) and 5-min APGAR (≤6 vs. >6: OR = 9.69) had a significant effect on the choice of initial respiratory support in VLBW infants (P<0.05).

Conclusion: The neonatal clinical condition may be a predictor of success for initial respiratory support at birth. Since the arterial duct may be open during the first hours of life, more study is needed to verify if early closure of the arterial duct may help increase the success rate of non-invasive respiratory support.
