Lung Recruitment Improves the Efficacy of Intubation-Surfactant-Extubation Treatment for Respiratory Distress Syndrome in Preterm Neonates, A Randomized Controlled Trial
Abstract Background: Lung recruitment is a maneuver in preterm neonates at birth, which may decrease the length of intubation. This study aimed to compare the therapeutic efficacy of lung recruitment plus intubation-surfactant-extubation (INSURE) procedure and INSURE alone for the preterm neonates with respiratory distress syndrome.Methods: A total of 184 preterm neonates with respiratory distress syndrome from 2017 to 2019 were enrolled and randomized into the lung recruitment group receiving lung recruitment (25 cm H2O for 15 seconds) plus INSURE and the control group receiving INSURE only. The primary outcome was the need for mechanical ventilation (MV) within 72 h after extubation. The secondary outcomes include the duration of intubation, noninvasive ventilation, total oxygen therapy, hospitalization, and other complications.Results: Compared to the control group, the lung recruitment group had a significantly lower proportion of preterm neonates need for MV within 72 h after extubation (23% vs. 38%, P=0.025) and pulmonary surfactant administration, as well as shorter the MV duration. Multivariate logistic regression analysis demonstrated that the control group had a 2.17-time higher risk for need for MV than the lung recruitment group (OR: 2.17, 95% CI: 1.13-4.18; P=0.021). In the mothers with hypertension, the infants presented a 2.41-time higher risk for requiring MV as compared with those of mothers with normotension (OR: 2.41, 95% CI: 1.15-5.05; P=0.020). Conclusion: These data suggested that lung recruitment plus INSURE can reduce the need for MV within 72 hours after extubation without increasing the incidence of complications and mortality.
