Randomized Controlled Trial Comparative Study Clinical TrialComparing the effects of nasal synchronized intermittent positive pressure ventilation (nSIPPV) and nasal continuous positive airway pressure (nCPAP) after extubation in very low birth weight infants.
In this study we hypothesized that nasal synchronized intermittent positive pressure ventilation (nSIPPV) would provide more ventilatory support than nasal continuous positive airway pressure (nCPAP) in the immediate post-extubation period in very low birth weight (VLBW) infants. We tested this hypothesis by comparing the effects of these two ventilatory techniques on ventilation, gas exchange, and patient inspiratory effort in 11 preterm infants immediately after extubation. All neonates studied (BW: 1141+/-(SEM) 53 g; GA: 28.1+/-(SEM) 0.5 wks) had received mechanical ventilation because of respiratory distress at birth and were extubated by day 14 of life. ⋯ In addition, Pe decreased by 30% during nSIPPV (P<0.01). TcPCO2 was statistically significantly lower during nSIPPV than nCPAP, and RR as well. These data therefore suggest that nSIPPV may provide more ventilatory support than nCPAP in the post-extubation period with less patient inspiratory effort.
