近几年关于防止产后出血和减少分娩第三期合并症的措施无显著改进。本文通过140例病人治疗分析肯定了PGF_(2α)对分娩第三期病人有良好作用。作者在本试验前做了2次预试验。首先是测定了13例分娩第三期病人的脐动脉压,将病人分3组,分别用PGF_(2α)(6例),麦角新碱(3例)和生理盐水(4例)静脉注射。从所得的脐动脉压的典型曲线显示:PGF_(2α)能显著增高脐动脉压并使其处于挛缩状态,而麦角新碱升压作用微小。第二次预试验是在20例妇女行剖腹产时,于胎儿娩出后,将PGF_(2α)1～2 mg直接注入子宫肌内,直观PG-冲
In recent years there has been no significant improvement in measures to prevent postpartum hemorrhage and reduce the third-stage complications of childbirth. In this paper, 140 cases of patients treated affirmed the PGF_ (2α) has a good effect on the third delivery of patients. The author did two preliminary tests before this test. First, the umbilical arterial pressure was measured in 13 cases of the third trimester of childbirth. The patients were divided into 3 groups, and were intravenously injected with PGF 2α (6 cases), ergometrine (3 cases) and saline (4 cases) respectively. The typical curve of umbilical arterial pressure obtained from this study shows that PGF 2α can significantly increase umbilical arterial pressure and make it contracture, while ergometrine is slightly hypertensive. The second pre-test was performed in 20 women with a caesarean section after the fetus was delivered and the PGF 2α was injected directly into the uterine muscle for an intuitive PG-punch
