Abstract:
Objective To investigate the effects of different angles of pulmonary surfactant(PS)administration on the incidence of bronchopulmonary dysplasia and intracranial hemorrhage in preterm infants.Methods A prospective study was conducted on 146 preterm infants(gestational age＜32 weeks)admitted to the Department of Neonatology,Provincial Hospital Affiliated to Anhui Medical University from January 2019 to May 2023.The infants were randomly assigned to different angles for injection of pulmonary surfactant groups:0° group(34 cases),30° group(36 cases),45° group(38 cases),and 60° group(38 cases).Clinical indicators and outcomes were compared among the groups.Results The oxygenation index was lower in the 60° group compared with the other three groups,with shorter invasive ventilation time and oxygen use time,and a lower incidence of bronchopulmonary dysplasia than the other three groups(P＜0.05).The incidence of intracranial hemorrhage was lower in the 60° group compared to the 0° group(P＜0.05).The cure rate in the 60° group was higher than that in the 0° group and the 30° group(P＜0.05).Conclusions The clinical efficacy of injection of pulmonary surfactant at a 60° angle is higher than other angles,reducing the incidence of intracranial hemorrhage and bronchopulmonary dysplasia in preterm infants.[Chinese Journal of Contemporary Pediatrics,2024,26(4):337-342]
