Does T-piece resuscitator in the delivery room improve the resuscitation efficacy on very preterm infants

Abstract

Objective To study the efficacy of T-piece resuscitator on the very preterm infants in the delivery room. Method Very preterm infants (gestational age 28~31 weeks) who needed positive pressure ventilation during delivery room resuscitation were included in the study between January 2010 and December 2015. Enrolled infants were randomly assigned to self-inflating bag group and T-piece group.Tracheal intubation ratio, duration of mechanical ventilation, continuous positive airway pressure (CPAP), supplementary oxygen through a nasal cannula and total oxygen requirement were compared between groups. The percentages of pneumothorax, sepsis, necrotizing enterocolitis (NEC), bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), intracranial hemorrhage and patent ductus arteriosus (PDA) between groups were also compared. Data were analyzed using independent sample t test and chi-square test. Result A total of 51 preterm infants were enrolled in this study, with 25 infants in the self-inflating bag group and 26 in the T-piece group. There was no statistically significant difference in the gender, gestational age, birth weight, Apgar scores, delivery mode and antenatal glucocorticoids between the two groups (P>0.05). The ratio of intubation in T-piece group was significantly lower than that in self-inflating bag group (15.4% vs. 44.0%, P 0.05). Conclusion Compared with the self-inflating bag group, the use of the T-piece in delivery room decrease the rate of tracheal intubation and the duration of mechanical ventilation and total oxygen requirement.
