A comparative study of two techniques of prostaglandin midtrimester abortion was performed. Patients were randomly assigned to either intra-amniotic prostaglandin F2 alpha or intravaginal prostaglandin E2 methods. Mean induction to abortion intervals were 9.99 +/- 6.18 and 9.19 +/- 2.59 hours, respectively. The incidence of side-effects for the two methods was similar. Both prostaglandin F2 alpha and E2 are considered to represent equivalent midtrimester abortifacients.
对两种孕中期前列腺素引产技术进行了一项对比研究。患者被随机分配至羊膜腔内注射前列腺素F2α或阴道内给予前列腺素E2方法组。平均引产至流产间隔时间分别为9.99±6.18小时和9.19±2.59小时。两种方法的副作用发生率相似。前列腺素F2α和E2均被认为是等效的孕中期堕胎药。
