Bubble CPAP versus Ventilator CPAP in Preterm Neonates with Early Onset Respiratory Distress--A Randomized Controlled Trial

UNLABELLED: Bubble continuous positive airway pressure (BCPAP) is a low cost nasal CPAP delivery system with potential benefits to developing nations. OBJECTIVE: To compare the efficacy and safety of BCPAP with ventilator-derived CPAP (VCPAP) in preterm neonates with respiratory distress. METHODS: In a randomized controlled trial, preterm neonates with Silverman-Anderson score ≥ 4 and oxygen requirement >30% within first 6 h of life were randomly allocated to BCPAP or VCPAP. Proportion of neonates with success or failure was compared. RESULTS: In all, 47 of 57 (82.5%) neonates from BCPAP group and 36 of 57 (63.2%) neonates from the VCPAP group completed CPAP successfully (p = 0.03). Neonates who failed CPAP had higher Silverman-Anderson score (p < 0.01), lower arterial to alveolar oxygenation ratio (p < 0.05) and needed surfactant more frequently (p < 0.01). CONCLUSION: BCPAP has higher success rate than VCPAP for managing preterm neonates with early onset respiratory distress, with comparable safety.
