Abstract:
Objective To explore the incidence rate and high-risk factors for bronchopulmonary dysplasia(BPD) in premature infants of mechanical ventilation.Methods From Jan 2008 to Dec 2009,196 very low birth weight infants with gestational age less than 32 weeks in our NICU were enrolled in the study.61 cases had the histories of mechanical ventilation.The clinical materials of 21 cases with BPD were compared to 41 cases without BPD in retrospective analysis.Results The total incidence of BPD in the very low birth weight infants with gestational age less than 32 weeks was 10.7%,and 34.4% in those infants with mechanical ventilation.The gestational age and birth weight of BPD group were lower than those without BPD,and the rates of premature rupture of fetal membrane and complicated neonatal respiratory distress syndrome (NRDS),postnatal infection,with long time intravenous nutrition in BPD group were higher than those without BPO control (P<0.05).Gender,asphyxia history,the use of pulmonary surfactant (PS),positive end-expiratory pressure,and mean airway pressure were not different significantly between two groups (P>0.05).Peak inspiratory pressure (PIP),the time of mechanical ventilation and oxygen administration were different significantly between two groups (P<0.05).NRDS,postnatal infection,the duration of ventilation,and hyperoxia were the risk factors for BPD,and the regression coefficient were 3.683,1.541,1.188 and 1.647.Conclusion Preventing premature,low birth weight,NRDS,shortening the duration of high peak inspiratory pressure and hyperoxia with mechanical ventilation and the use of the parenteral nutrition,managing the infection of the prenatal and postnatal are the key points of preventing BPD.
