Abstract

To compare the performance of self-inflating bag (SIB) with T-piece resuscitator (TPR) in neonatal resuscitation. Methods This study involved the trainees participating in a Neonatal Resuscitation Simulation Camp (NRSC) organized by Shanghai First Maternity and Infant Hospital in December 2019. They were trained to provide positive pressure ventilation with the two devices on artificial lungs. Ventilation parameters including peak inspiratory pressure (PIP), positive end-expiratory pressure (PEEP), PIP in pulmonary alveoli (PIPalv), mean airway pressure (MAP), frequency, inspiratory time (Ti), tidal volume and minute ventilation volume were recorded and analyzed by independent sample t-test or rank sum test. Results The PIPalv, PIP, oxygen flow rate, tidal volume and minute ventilation volume delivered by TPR were significantly lower than those by SIB [(17.18±1.61) vs (24.05±4.29) cmH2O (1 cmH2O=0.098 kPa), t=-6.87; (17.91±1.35) vs (29.97±4.50) cmH2O, t=-14.06; (3.65±0.25) vs (6.88±1.59) L/min, t=-11.33; (15.90±1.81) vs (24.02±4.29) ml/min, t=-10.99; (664.71± 88.94) vs (1 069.49±205.68) ml/min, t=-9.89; all P<0.001]. However, compared with SIB, the PEEP in pulmonary alveoli, Ti, duration of ventilation, inspiratory to expiratory ratio were increased when using TPR [(4.76(4.69-5.57) vs 0.19(0.12-4.10) cmH2O, T=1 190.00; (0.59±0.15) vs (0.43±0.09) s, t=5.01; (1.46±0.23) vs (1.36±0.11) s, t=2.15; 0.71±0.22 vs 0.47±0.13, t=5.14; all P<0.05]. Conclusion TPR could deliver more stable and safer PIP, PEEP and tidal volume than SIB and keeping MAP at a stable level during positive pressure ventilation on artificial lungs.
