Operative vaginal delivery (OVD) refers to the use of an instrument (forceps or vacuum device) to assist with the delivery of the fetus from the vagina. This can help improve maternal and fetal outcomes and has to be weighed up against the risks and benefits of performing second-stage cesarean deliveries. OVD forms an integral part of basic emergency obstetric care and a skilled birth attendant's duties. Outlet forceps and vacuum extraction should be used to shorten the second stage of labor and to improve maternal and fetal outcomes associated with delayed second stage. Despite the known benefit of OVD, available data on the use of OVDs in low- and middle-income countries show very low rates, mostly due to the lack of skilled healthcare workers and equipment shortages. Increased use of OVD can safely reduce the number of second-stage cesarean deliveries with its associated morbidity and mortality. We recommend implementing training programs to increase the number of skilled healthcare workers and strengthening health systems to provide birthing facilities with the equipment required to perform OVD.
阴道分娩(operative vaginal delivery,OVD)是指使用器械(产钳或真空吸引器)辅助胎儿从阴道娩出。这有助于改善母婴结局,需要权衡与实施第二产程剖宫产相关的风险和益处。OVD 是基本产科急救和熟练助产士职责的重要组成部分。应使用出口产钳和真空吸引器来缩短第二产程,改善与第二产程延长相关的母婴结局。尽管 OVD 的益处是已知的,但在中低收入国家,有关 OVD 使用的数据显示使用率非常低,主要是由于缺乏熟练的卫生保健工作者和设备短缺。增加 OVD 的使用可以安全地减少第二产程剖宫产的数量及其相关的发病率和死亡率。我们建议实施培训计划,以增加熟练卫生保健工作者的数量,并加强卫生系统,为实施 OVD 提供所需的分娩设施和设备。
