摘要(Abstract)：
目的:分析硬膜外分娩镇痛时机对初产妇妊娠结局的影响。方法:选取2019年10月1日至2020年9月30日在山东大学第二医院实施硬膜外分娩镇痛的孕妇共502例。根据硬膜外分娩镇痛时的宫口扩张程度分为3组:Ⅰ组(宫口<2cm, 49例),Ⅱ组(2≤宫口<3cm, 284例),Ⅲ组(宫口≥3cm, 169例)。分析3组孕妇的分娩方式及分娩并发症的差异。结果:中转剖宫产率I组>Ⅱ组>Ⅲ组(P=0.009)。宫口<2cm行分娩镇痛中转剖宫产率明显升高(OR>1,P=0.012)。3组孕妇产程中或产后发热、产后出血、产后尿潴留及新生儿窒息发生率比较,差异无统计学意义(P>0.05)。产程中缩宫素使用率:Ⅰ组>Ⅱ组>Ⅲ组,产程中使用缩宫素是产后出血的危险因素(P=0.029)。结论:宫口扩张≥2cm实施硬膜外分娩镇痛,中转剖宫产率、产程中缩宫素使用率相对较低,为较为适宜分娩镇痛时机。
