妊娠中期经腹选择性减胎术临床应用

目的:探讨妊娠中期经腹选择性减胎术的方法及妊娠结局。方法:选择1999年12月～2010年6月在郑州大学第一附属医院妊娠中期因多胎或1胎畸形行减胎术的患者35例,分析中期减胎方法、减胎手术并发症、平均分娩孕周、新生儿出生体重等,并比较减胎后保留单胎或双胎新生儿出生体重和分娩孕周。结果:35例妊娠中期减胎患者均无术后出血、羊水溢漏、术后早期流产、凝血障碍;术后晚期流产3例(占8.57%),平均分娩孕周为(34.62±4.05)周,新生儿平均出生体重为(2.31±0.64)kg。妊娠中期减灭1胎和减灭2胎患者术后并发症无明显差异。保留单胎组平均分娩孕周(36.44±2.83)周,新生儿平均出生体重为(2.63±0.57)kg;保留双胎组平均分娩孕周(34.13±2.77)周,新生儿平均出生体重为(1.96±0.53)kg,两组患者相比,平均分娩孕周和新生儿出生体重均有统计学差异。结论:妊娠中期减胎术可作为避免多胎妊娠、异常胎儿出生的安全、简便、有效方法;保留单胎者妊娠结局优于保留双胎者。
