Bubble Nasal Continuous Positive Airway Pressure (bCPAP) versus Control in Neonates with Respiratory Distress.

ABSTRACT

OBJECTIVE: To compare the effectiveness of bubble continuous positive airway pressure (bCPAP) and oxygen inhalation via nasal cannula in neonates presenting with respiratory distress, using Silverman Anderson Retraction Score (SARS). STUDY DESIGN: Randomised clinical trial. PLACE AND DURATION OF STUDY Department of Paediatrics, Unit-1, KEMU/Mayo Hospital, Lahore, Pakistan, from April 2017 to June 2018. METHODOLOGY: A total of 120 neonates fulfilling inclusion and exclusion criteria were enrolled and were randomly allocated in two groups Group A and Group B. In group A, neonates were given bCPAP for respiratory support, while neonates in group B were given nasal oxygen as control group. Neonates in both groups were followed for 48 hours. The effectiveness was determined by the reduction in SARS, up to or less than score 3, at the end of a 48-hour period. Data were collected and analysed by SPSS version 20.0. P-value ≤0.05 was taken as significant. RESULTS: In Group A, effectiveness was found to be 93.3%, and in Group B effectiveness was 71.7% (p = 0.003). Median reduction in SARS from 00 to 48 hours, in group A (bCPAP) was 4 (4 - 5) while in group B (control), it was 3 (2 - 3); statistically significant (p <0.001). CONCLUSION: Bubble CPAP was more effective than nasal oxygen alone, in treatment of respiratory distress among neonates. This study suggested that bCPAP should be used more frequently in NICUs of Pakistan to reduce burden of neonatal morbidity due to respiratory distress.
