Abstract
Background. : Positive pressure ventilation (PPV) is provided by manual ventilation devices such as self-inflating bags (SIB), flow inflating bags and T-piece resuscitators. The objective of this study is to compare the effect of type of manual ventilation device on overall response to resuscitation among preterm neonates born < 35 weeks gestation.
Methods. Retrospective data were collected in 2 time periods. Primary outcome was overall response to resuscitation as measured by Apgar score. Secondary outcomes were incidence of airleaks, need for chest compressions/epinephrine, need for intubation and surfactant use.
Results. 294 resuscitations requiring PPV were identified. 135 neonates had SIB used and 159 neonates had T-piece used to provide PPV. There was no significant difference in 1 and 5 minute Apgar scores between devices (P=0.770, P=0.105 respectively) nor were there significant differences in secondary outcomes. The rate of rise of Apgar scores was higher by 0.47 for the T-piece compared to the SIB (95%CI=0.08, 0.87, P=0.019)
Conclusion. Although some manikin studies favor the T piece device in providing reliable and consistent pressures, our experience did not indicate significant differences in effectiveness of resuscitation between the T piece and SIB in preterm resuscitations.
