OBJECTIVE: To study the safety of two ventilator weaning strategies after high-frequency oscillatory ventilation (HFOV) for the treatment of neonatal respiratory distress syndrome (NRDS) in preterm infants.
METHODS: A prospective randomized controlled trial was conducted for 101 preterm infants with NRDS, with a gestational age of ≤32+6 weeks or a birth weight of ≤1 500 g, who were admitted to the neonatal intensive care unit of Xiamen Maternal and Child Health Hospital from January 1, 2019 to June 30, 2020. The infants underwent HFOV as the preferred treatment. The infants were randomly divided into an observation group (50 infants with direct weaning from HFOV) and a control group (51 infants with weaning after HFOV was switched to conventional mechanical ventilation). The two groups were compared in terms of failure rate of ventilator weaning within 72 hours, changes in blood gas parameters at 2 hours before weaning and at 2 and 24 hours after weaning, respiratory support therapy, incidence rates of complications, and outcome at discharge.
RESULTS: There was no significant difference in the failure rate of ventilator weaning within 72 hours (8% vs 14%, P > 0.05). The observation group had a significantly shorter duration of mechanical ventilation than the control group [(64±39) hours vs (88±69) hours, P < 0.05]. There were no significant differences between the two groups in the duration of mechanical ventilation, total oxygen supply time, blood gas parameters before and after ventilator weaning, incidence rates of complications, and outcome at discharge (P > 0.05).
CONCLUSIONS: For preterm infants with NRDS, the strategy of weaning directly from HFOV is safe and reliable and can reduce the duration of invasive mechanical ventilation, and therefore, it holds promise for clinical application.
