Safety of two ventilator weaning strategies after high-frequency oscillatory ventilation in preterm infants with respiratory distress syndrome: a prospective randomized controlled trial / 中国当代儿科杂志

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@*RESULTS@#There was no significant difference in the failure rate of ventilator weaning within 72 hours (8% vs 14%, @*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.

Research advances in the methods for weaning from high-frequency oscillatory ventilation in neonates / 中国当代儿科杂志

Neonatal respiratory failure is a serious clinical illness commonly seen in the neonatal intensive care unit (NICU). Although clinicians want to maximize noninvasive respiratory support, some low-birth-weight preterm infants may require invasive respiratory support from the beginning. As an important respiratory management technique for the treatment of respiratory failure, high-frequency oscillatory ventilation (HFOV) allows gas exchange by rapid delivery at a tidal volume lower than or equal to anatomy death volume. Continuous distending pressure was applied to achieve uniform lung expansion, reduce repeated contraction of lung tissue, and exert a protective effect on lung tissue, and so it is preferred by clinicians and has been widely used in clinical practice. However, no consensus has been reached on the methods for weaning from HFOV. This article reviews the methods for weaning from HFOV, so as to provide help for clinical practice.
