This study aimed to compare the effectiveness of RAM cannula and short binasal prongs (SBP) in providing CPAP to preterm infants with respiratory distress syndrome. The results showed that there was no significant difference in CPAP failure rates between the RAM cannula and SBP groups. However, the RAM cannula group had less nasal trauma and shorter duration of CPAP.
To determine if RAM cannula is non-inferior to short binasal prongs (SBP) in providing nasal continuous positive airway pressure (CPAP) in preterm infants with respiratory distress syndrome (RDS). In this randomized, open-label, noninferiority trial from a low-middle-income country, we enrolled 254 preterm infants (28-34 weeks gestational age) with RDS who needed CPAP as primary respiratory support. The eligible infants were randomized to either RAM cannula or SBP interface groups. The primary outcome was CPAP failure (defined as the need for intubation or non-invasive positive pressure ventilation) within 72 h of randomization. The noninferiority margin was defined as a 10% or less absolute difference in CPAP failure rates. The secondary outcomes included nasal trauma and adverse events. We analyzed by per-protocol (primary) and intention to treat. CPAP failure has been seen in 25 infants (19.7%) in the RAM cannula group versus 22 (17.3%) in the SBP group (RD -2.36%; 95% CI-11.9 to 7.2 [beyond inferiority margin]; p = 0.6). Moderate and severe nasal trauma was less in RAM cannula (2.4 vs. 8.7%; RR 0.27; 95% CI 0.08-0.95; p 0.028). Duration of CPAP was also significantly shorter in the RAM cannula group (MD -12.4 h; 95% CI -20.34 to -4.46, p 0.017). There were no differences in other adverse events. Conclusions: RAM cannula was not non-inferior to SBP in providing CPAP to preterm infants with respiratory distress syndrome.
