目的观察产时超声联合Kielland’s产钳在第二产程中的应用效果。方法选取2020年8月至2022年8月在湖州市妇幼保健院进行足月分娩的产妇350例进行回顾性分析,根据应用超声辅助Kielland’s产钳助产情况,分为观察组(n=242)和对照组(n=108)...目的观察产时超声联合Kielland’s产钳在第二产程中的应用效果。方法选取2020年8月至2022年8月在湖州市妇幼保健院进行足月分娩的产妇350例进行回顾性分析,根据应用超声辅助Kielland’s产钳助产情况,分为观察组(n=242)和对照组(n=108)。观察组在第二产程中应用超声辅助Kielland’s产钳进行助产分娩,对照组进行二程剖宫产。比较两组产妇和新生儿的并发症情况,包括产妇产后出血、绒毛膜羊膜炎、产后尿潴留、产后发热等,以及新生儿窒息和新生儿重症监护病房(neonatal intensive care unit,NICU)入住情况。结果观察组的产后出血、绒毛膜羊膜炎及住院天数均低于对照组,产后尿潴留发生率高于对照组,差异均有统计学意义(P<0.05);两组的新生儿NICU入住率及窒息率比较,差异均无统计学意义(P>0.05)。结论产时超声联合辅助Kielland’s产钳分娩,不仅不增加产妇或新生儿不良妊娠结局的发生,反而可以实现阴道助产,改善分娩结局,降低剖宫产率。展开更多
