Effects of Different Duration of Prone Position Ventilation on Respiratory Function in Premature Infants
Objective To explore the effects of different duration of prone position ventilation on respiratory function in premature infants,and to provide reference for clinical practice.Methods From December 2020 to December 2021,89 premature infants hospitalized in the Neonatal Intensive Care Unit in a tertiary A hospital in Xi'an were selected by the convenience sampling method.They were divided into group A(n=30),group B(n=30)and group C(n=29)by random number table method.Group A was ventilated in the supine position,while group B and C were ventilated in the prone position for 1 hour and 2 hours each time respectively.The duration of non-invasive mechanical ventilation,oxygen therapy time,weaning success rate,arterial blood gas index,incidences of related complications and adverse reactions were recorded in 3 groups respectively.Results The duration of non-invasive mechanical ventilation and oxygen therapy in group B and C were lower than those in group A,and the differences were statistically significant(all P＜0.05).The success rate of weaning and the incidence of bronchopulmonary dysplasia in group C were lower than those in group A,and the differences were statistically significant(all P＜0.017).After 2 and 3 days,the arterial blood gas indexes of group C were better than those of group A,and the differences were statistically significant(all P＜0.017).The main effects of intervention on the values of each index were statistically significant(all P＜0.05).Conclusion In premature infants,intermittent prone position during non-invasive mechanical ventilation can improve pulmonary oxygenation function,and the duration of 2 h is more effective.
