Postpartum hemorrhage is most common cause of maternal mortality. Active management of third stage of labor minimizes the risk of postpartum hemorrhage. To compare the effect of methylergonovine and 15-methyl prostaglandin F2α (15-methyl PGF2α) in active management of third stage of labor.
A randomized open labelled parallel study with 50 women in normal labor, 25 in each group were included. The drugs methylergonovine (0.2 mg) intravenous and 15-methyl PGF2α (250 µg) intramuscular were administered at the time of delivery of anterior shoulder. Main outcomes measured were amount of blood loss during the first four hours of delivery and objective measurement of hemoglobin and hematocrit levels before delivery and third day postpartum.
There was no statistically significant difference in the blood loss between the two groups at delivery (P = 0.130), at 1 hour of delivery (P = 0.453). The blood loss with 15-methyl PGF2α was significantly less as compared to that of blood loss with methylergonovine at four hours of delivery (P = 0.014) and the total, i.e., during first four hours, amount of blood loss was significantly less with 15-methyl PGF2α (P = 0.026). There was no statistically significant difference in the hemoglobin and hematocrit levels measured predelivery and postpartum third day between both the drugs.
Both the drugs were effective in controlling the amount of blood loss during the third stage of labor, 15-methyl PGF2α being more efficacious.
产后出血是孕产妇死亡的最常见原因。积极处理第三产程可将产后出血风险降至最低。比较甲基麦角新碱和15-甲基前列腺素F2α(15-甲基PGF2α)在积极处理第三产程中的效果。
一项随机开放标签平行研究,纳入50例正常分娩的妇女,每组25例。在娩出前肩时静脉注射甲基麦角新碱(0.2mg)和肌内注射15-甲基PGF2α(250μg)。主要测量指标为分娩后前4小时的失血量,以及分娩前和产后第三天血红蛋白和血细胞比容水平的客观测量值。
两组在分娩时(P = 0.130)、分娩后1小时(P = 0.453)的失血量无统计学显著差异。在分娩后4小时,15-甲基PGF2α组的失血量明显少于甲基麦角新碱组(P = 0.014),且在整个前4小时内,15-甲基PGF2α组的总失血量明显较少(P = 0.026)。两种药物在分娩前和产后第三天测量的血红蛋白和血细胞比容水平上无统计学显著差异。
两种药物在控制第三产程失血量方面均有效,15-甲基PGF2α更有效。
