| 摘要 目的：探讨产程时间及产程干预对单胎足月初产妇宫缩乏力性产后出血的影响。方法：本次研究纳入2017年1月-2020年12月于我院分娩单胎足月初产妇患者，根据第一产程时间并通过PSM法匹配分组，第一产程时间＜8 h和≥8 h产妇各771例；分析一般资料、产程时间及宫缩乏力性产后出血发生情况，评价产程时间及产程干预与宫缩乏力性产后出血发生情况间关系。结果：两组年龄、孕次及孕周比较差异无统计学意义（P>0.05）；≥8 h组及各亚组第二产程时间和第一产程+第二产程时间均显著长于＜8 h组（P<0.05）；≥8 h组、16~20 h组及≥20 h组产后出血率均显著高于＜8 h组（P<0.05）；接受或未接受产程干预情况下≥8 h组第二产程时间和和第一产程+第二产程时间均显著长于＜8 h组（P<0.05）；≥8 h和＜8 h组接受产程干预后第一产程时间、第二产程时间及第一产程+第二产程时间均显著长于未接受产程干预（P<0.05）；≥8 h组接受产程干预后产后出血率显著高于未接受产程干预（P<0.05）。结论：单胎足月初产妇宫缩乏力性产后出血发生随第一产程时间增加而升高，同时第二产程时间往往随第一产程时间增加而增加。 |

| ABSTRACT Objective: To investigate the influence of labor process time and intervention on postpartum hemorrhage caused by uterine atony in singleton full-term primipara. Methods: Singleton full-term primipara were chosen in the period from January 2017 to December 2020 in our hospital and were grouped according to the first stage time of labor and matched by PSM method included ＜8 h group and ≥8 h group each with 771 cases. The general information, duration of labor and uterine atony postpartum hemorrhage were analyzed and the relationship between the time and intervention of labor process and the occurrence of postpartum hemorrhage due to uterine inertia were evaluated. Results: There was no significant difference in age, gestational times and gestational weeks between 2 groups（P>0.05）. The second stage time of labor and the first stage + second stage of labor in gestational weeks between 2 groups inertia were evaluated. relations（P<0.05）. The postpartum hemorrhage rate of tage + second stage of labor in gestational weeks between 2 groups inertia h group（P<0.05）. The second stage of labor and the first stage + second stage of labor in ional weeks between 2 groups inertia were evaluated. relationship between intervention（P<0.05）. The first, second and first stage + second stages of labor of f laboroup and < 8 h group with labor intervention were significantly longer than without labor intervention（P<0.05）. The postpartum hemorrhage rate of rvention were significantly longer than without laborhigher than without labor intervention（P<0.05）. Conclusion: The incidence of postpartum hemorrhage due to uterine atony in singleton term primipara increased with the increased of the first stage time of labor, while the second stage time of labor often increased with the increased of the first stage time of labor. |
