孕中期经腹氯化钾减胎术的临床应用

目的探讨孕中期经腹氯化钾(KCl)减胎术的方法及妊娠结局。方法选择孕中期因多胎妊娠或双胎妊娠者有1胎异常的孕妇进行超声引导下经腹KCl减胎术,分析减胎方法、术后并发症和妊娠结局等。结果 9例妊娠中期经腹KCl减胎术均成功。1例术后流产,1例晚期流产,术后2周流产率11.10%。保留双胎2例,平均分娩孕周33+4周,新生儿出生体重(1.94±0.18)kg;保留单胎4例,平均分娩孕周39+3周,新生儿出生体重(3.26±0.14)kg;妊娠随访中1例。结论超声引导下孕中期经腹KCl减胎术可作为避免多胎妊娠及异常胎儿出生的安全、简便、有效方法。

Clinical application of transabdominal fetal reduction usingpotassium chloride during the second trimester

Objective To summarize the method and outcome of transabdominal fetal reduction using potassium chloride （KC1） during the second trimester. Methods 9 cases with multiple pregnancy or abnormal fetus and were received transabdominal fetal reduction using KC] under ultrasound guidance. The methods of fetal reduction, postoperative complications and outcome were analyzed. Results The second - trimester transabdominal fetal reduction of all cases were successful. 1 case was postoperative miscarriage and 1 case was late - term miscarriage, with miscarriage rate of 11.10%. 2 cases retained twin fetuses, the average gestational age were 33 ＋4 weeks and the average neonatal birth weight was （ 1.94 ± 0. 18 ） kg. 4 cases retained singleton fetus, the average gestational age were 39＋3a weeks and the average neonatal birth weight was （3.26 ±0. 14） kg. 1 case is still follow - up. Conclusion The fetal reduction using KC] during the second trimester of pregnancy can be used as a safe, simple and effective method to avoid multiple pregnancy and the birth of abnormal fetuses.
