Abstract

Objective: Application of Continuous Positive Airway Pressure (CPAP) in neonate with respiratory distress is associated with reduction of respiratory failure, reduced complications and mortality. Bubble CPAP (B-CPAP) and ventilator-derived CPAP (V-CPAP) are two most popular CPAP modes. We aimed to determine whether B-CPAP and V-CPAP would have different survival rate and possible complications.

Methods: This prospective clinical trial was performed on 50 preterm neonates weighing 1000-2000 gr who were admitted to the neonatal intensive care unit of Afzalipoor Hospital because of respiratory distress between June 2009 and May 2010. Patients were randomly allocated into treatment groups using minimization technique. Survival analysis was applied to estimate and compare survival rates. Duration of oxygen therapy, hospital stay as well as hospitalization costs were compared using independent sample t-test.

Findings: Estimated survival rates at 24 hours in B-CPAP and V-CPAP groups were 100% and 77% respectively. Corresponding figures at 48 hours were 100% and 71%. In addition the hospitalization cost in V-CPAP group was significantly higher than in B-CPAP group.

Conclusion: According to our results, B-CPAP was effective in the treatment of neonates who were suffering from respiratory distress and reduced the duration of hospital stay. In addition to mentioned benefits, its low cost may be the reason to use B-CPAP broadly compared with V-CPAP.
