摘　　要：目的应用Robson分类系统,分析"全面二孩"政策后产妇特征及剖宫产变化。方法回顾性采集2017—2019年某专科医院住院分娩的25425例围生期产妇资料,采用Robson分类系统描述产妇人群构成比、剖宫产率与权重,分析其3年变化。结果剖宫产总数9669例,总剖宫产率38.03%。NI&NC组产妇构成比最大,占30.88%;PC组剖宫产权重最大,占43.48%。人群构成比3年分析,PC组差异有统计学意义(P<0.05);年度两两比较中,2019年与前2年差异均有统计学意义(P<0.005)。剖宫产率3年分析,NI&NC组差异有统计学意义(P<0.05);PT组3年剖宫产率比较,差异有统计学意义(P<0.05)。剖宫产权重3年分析,PC组、NI&NC组差异有统计学意义(P<0.05)。PC组年度两两比较中,2019年与前2年差异均有统计学意义(P<0.05)。结论 "全面二孩"政策后,瘢痕子宫产妇数量急增,成为剖宫产第一大权重,2018年达高峰,2019年有所下降。提高初产妇引产成功率,严格控制临产前剖宫产是产科临床降低剖宫产率的关键。Objective To apply Robson classification system to analyze the maternal characteristics and changes of cesarean section after the "comprehensive two-child" policy.Methods The data of 25425 perinatal women who were hospitalized in a specialty hospital from 2017 to 2019 were retrospectively collected.The Robson classification system was used to describe the maternal population composition,cesarean section rate and weight,and the 3-year changes were analyzed.Results The total number of cesarean sections was 9669,and the total cesarean section rate was 38.03%.The NI&NC group had the largest proportion of women,accounting for 30.88%;the PC group had the largest weight of cesarean section,accounting for 43.48%.In the three-year analysis of population composition ratio,the difference in the PC group was statistically significant(P<0.05);in the annual pairwise comparison,the difference between 2019 and the previous two years was statistically significant(P<0.005).In the 3-year analysis of the cesarean section rate,the difference in the NI&NC group was statistically significant(P<0.05);the difference in the 3-year cesarean section rate in the PT group was statistically significant(P<0.05).After a 3-year analysis of the weight of cesarean section,the difference between the PC group and the NI&NC group was statistically significant(P<0.05).In the annual pairwise comparison of the PC group,the difference between 2019 and the previous two years was statistically significant(P<0.05).Conclusion After the "comprehensive two-child" policy,the number of women with scarred uterus has increased sharply,becoming the largest weight for cesarean section,reaching its peak in 2018 and decreasing in 2019.Improving the success rate of primiparas and strictly controlling the cesarean section before delivery is the key to reducing the cesarean section rate.
