摘要 目的:探讨支气管肺发育不良(BPD)的高危因素及与纤溶酶原激活物抑制剂-1(PAI-1)的关系。方法:回顾性分析我院NICU 2010年1月至2012年12月胎龄≤32周并存活28 d以上VLBW96例的临床资料,以BPD发生与否分组,进行危险因素分析,同时ELISA法测定两组间PAI-1的表达。结果:BPD组胎龄及出生体重均较非BPD组低,BPD组合并新生儿呼吸窘迫综合征(NRDS)、呼吸机相关性肺炎(VAP)、应用机械通气,最高氧浓度较非BPD组明显增高,差异异有显著性(P<0.05);性别、合并窒息及PS的应用两组之间无明显差异(P>0.05)。多因素Logistic回归分析显示结果提示胎龄、出生时体重是发生BDP的保护性因素,合并NRDS、机械通气最高氧浓度为发生BPD的独立危险因素。各时间点组间比较BPD组PAI-1的表达明显高于非BPD组,差异有显著性意义(P<0.05)。结论:预防早产及感染,降低机械通气最高氧浓度是预防BPD发生的重要措施,PAI-1参与了BPD的发病过程。
