BACKGROUND: There is inadequate evidence regarding which noninvasive ventilation (NIV) is superior for initial respiratory support of preterm infants with respiratory distress syndrome. OBJECTIVES: To compare the failure of noninvasive ventilation (NIV) and neonatal outcomes between nasal continuous positive airway pressure (NCPAP), bi-level positive airway pressure (BiPAP), and nasal intermittent positive pressure ventilation (NIPPV) as the initial respiratory support with less invasive surfactant administration (LISA) in very low birth weight (VLBW) infants. METHODS: Medical records of 419 VLBW infants born at 26-30weeks' gestation who did not require intubation in the delivery room and were initially supported with either NCPAP (n=221), BiPAP (n=101), or NIPPV (n=97) were retrospectively reviewed. The LISA approach was preferred in cases of surfactant requirement. The primary outcome was the failure of NIV within the first 72h of life. Failure of NIV was defined as the persistence or recurrence of one or more of the following: hypoxemia, respiratory acidosis, more than one episode of apnea requiring bag and mask ventilation or more than six episodes of apnea requiring stimulation over a 6-h period. Data were analyzed using univariate and multivariate logistic regression analysis. RESULTS: Failure of NIV within the first 72h of life was significantly higher in the NCPAP group (29.4%) compared with the BiPAP (12.9%) or NIPPV (12.4%) group (P<0.001). However, the BiPAP and NIPPV groups were not different in terms of NIV failure (P=0.91). Multivariable logistic regression analysis showed that antenatal steroid administration (OR: 0.49, 95% CI: 0.27-0.90; P=0.02) and gestational age˂28weeks (OR: 2.03, 95% CI: 1.18-3.49; P=0.01) were independent factors that influence failure of NIV within the first 72h of life. CONCLUSION: Compared with NCPAP, the use of NIPPV/BiPAP strategies for initial respiratory support can reduce the need for invasive ventilation in infants born at 26-30weeks' gestation.
