BackgroundIn China, the growing prevalence of bronchopulmonary dysplasia (BPD) in increased number of survived very preterm and extremely preterm infants, seriously endangers the life and impairs quality of life in this population. There are different degrees of hemodynamic changes in preterm infants in the process of developing BPD, however, there are relatively few studies about the correlation between the occurrence of BPD and hemodynamic indicators in preterm infant.ObjectiveTo examine predictive value of the hemodynamic indexes for BPD in premature infants.MethodsOne hundred and sixty-one premature infants (hospitalized within 1 hour of birth, gestational age 0.05) . Preterm infants with BPD had higher incidence of neonatal asphyxia, neonatal respiratory distress syndrome, neonatal pneumonia, and retinopathy of prematurity than those without (P0.05) . PI values at 1, 12 and 24 hours after birth differed significantly between the two groups (P0.05) . In predicting BPD, the PI at 1-hour, 12-hour, and 24-hour was 0.847〔95%CI (0.788, 0.906) , P |
