本文报导 PGF_(2α)羊膜腔内和腔外注射各20例进行中期妊娠引产的比较。羊膜腔内组在羊膜腔穿刺后注入40mg PGF_(2α)如24小时后不流产或已破膜者给50单位催产素(S-yntocinon)静脉滴注直至流产。羊膜腔外组用一根导尿管通过宫颈注射40mg PGF(2α)Tylose 胶冻于羊膜腔外间隙,每六小时注射一次直至流产。羊膜腔内和腔外组的平均年龄、平均孕周、初孕妇的比例、流产史、足月产史等均相仿。羊膜腔内组的引产时间为27.6小时,羊膜腔外组则为12.1小时,两组差异显著(P<0.001 t 试验)两组均无一
This article reports the comparison of 20 cases of PGF_ (2α) intra-amniotic and extra-cardiac injection for mid-term pregnancy induced labor. Amniotic cavity group after amniocentesis 40mg PGF_ (2α) If 24 hours after abortion or rupture of the membrane to 50 units of oxytocin (S-yntocinon) intravenous infusion until abortion. Amniotic cavity group with a catheter through the cervical injection of 40mg PGF (2α) Tylose jelly in the amniotic space, injected once every six hours until abortion. The average age of amniotic cavity and extraluminal group, the average gestational age, the proportion of early pregnant women, abortion history, full-term history are similar. The time to induction of labor was 27.6 hours in the amniotic cavity group and 12.1 hours in the amniotic group, with no significant difference between the two groups (P <0.001 t test)
