Abstract:Objective To study the clinical efficacy of volume-targeted ventilation (VTV) versus high-frequency oscillatory ventilation (HFOV) in the treatment of neonatal respiratory distress syndrome (NRDS). Methods A retrospective cohort analysis was performed on the medical data of 140 neonates with severe NRDS who were admitted from September 2016 to February 2022, with 55 neonates in the VTV group and 85 in the HFOV group. The neonates in the VTV group received conventional mechanical ventilation and target tidal volume, and those in the HFOV group received HFOV. Arterial blood gas parameters were collected at 48 hours after admission, and related indices during hospitalization were recorded, including mortality rate, duration of invasive mechanical ventilation, duration of oxygen therapy, and the incidence rates of complications. Results Compared with the VTV group, the HFOV group had significantly lower incidence rates of grade Ⅲ-Ⅳ periventricular-intraventricular hemorrhage and neonatal necrotizing enterocolitis (P<0.05), and there were no significant differences between the two groups in the duration of invasive mechanical ventilation, the duration of oxygen therapy, mortality rate, and the incidence rates of bronchopulmonary dysplasia, hypocapnia, hypercapnia, periventricular leukomalacia, and retinopathy of prematurity (P>0.05). Conclusions HFOV has a better clinical efficacy than VTV in the treatment of NRDS.
