ABSTRACT
Objective To investigate the relationship between histological chorioamnionitis (HCA),funisitis (FV) and lung injury in preterm infants.Method Data of preterm infants with gestational age of less than 34 weeks,who were born in our Hospital and admitted to the neonatal ward during the period of October 2015 to August 2016 were retrospectively collected.According to reports of placenta pathologies,participants were assigned into three groups,non-infection group,HCA group and HCA + FV group.Demographic and infectious characteristics,duration of respiratory support,partial pressure of oxygen (PaO2) and pulmonary function testing results at corrected gestational age 40 weeks were compared among groups.Result A total of 151 preterm infants were included,with 33 cases in noninfection group,61 cases in HCA group and 57 cases in HCA + FV group.Non-invasive ventilation duration and number of days in room air in HCA + FV groups were both longer than those in the non-infection group [0 (0,66) h vs.0 (0,0) h,65 (0,176) h vs.0 (0,8) h].The duration of invasive ventilation and total ventilation days in HCA + FV group were longer than those of the other two groups [0 (0,4) h vs.0 (0,0) and 0 (0,0) h,0 (0,99) h vs.0 (0,0) and 0 (0,52) h],the differences were statistically significant (P < 0.05).However,there was no significant difference of PaO2 after 0.5 hour respiratory support among the three groups (P > 0.05).Pulmonary functional parameters,such as respiratory frequency,VPEF/TE,VPEF/VE,VPEF and TPEF,gradually decreased with the degree of inflammatory progress,but there was no statistically significant difference (P > 0.05).Conclusion HCA and FV are highly associated with premature lung injury.The worse the placental inflammation is,the longer respiratory support duration will be needed or required.However,HCA and FV may have no significant effect on lung function.
