催产素(Oxytocin)和甲基麦角新硷(mthergin)等子宫收缩药是为控制弛缓出血和刮宫术时的出血而广泛采用的药物,但另一方面关于这些药物的副作用,特别是对血液动态的影响也有许多报道。最近,Secher,N.J 氏等详细地分析了催产素和甲基麦角新硷对体循环系统和肺循环系统的作用。为除外由子宫收缩引起的血液动态变化,全部以妊娠10至12周接受刮宫术的9名患者为对象。单独静注催产素5至10单位,30至40秒钟后,股动脉压和末梢循环阻力分别降低
Ovarian hormones such as Oxytocin and mther are widely used drugs to control bleeding during hemorrhage and curettage but on the other hand the side effects of these drugs, especially on blood dynamics There are many reports of the impact. Recently, Secher, N.J. et al. Analyzed in detail the effects of oxytocin and methylergonium on the systemic and pulmonary circulatory system. To exclude the dynamic changes in blood caused by uterine contractions, all 9 patients undergoing curettage between 10 and 12 weeks gestation were enrolled. Oxytocin alone intravenous injection of 5 to 10 units, 30 to 40 seconds after the femoral artery pressure and peripheral circulation resistance decreased
