摘　　要：目的探讨胎儿心内注射氯化钾+羊膜腔穿刺注射利凡诺用于中、晚孕期中央性前置胎盘(状态)引产的安全性。方法对18例孕中、晚期因中央性前置胎盘(状态)要求终止妊娠者于B超引导下行胎儿心脏穿刺注射10%氯化钾+羊膜腔穿刺注射利凡诺引产,观察总引产时间、总产程和出血量。结果 18例患者均经阴道分娩,平均总引产时间27h 12 min,平均总产程7 h 19 min,平均出血量265 mL,无1例发生产后出血。结论胎儿心脏穿刺注射氯化钾的方法用于中、晚孕期中央性前置胎盘(状态)终止妊娠的治疗是一种安全、简便、有效的方法,值得推广。Objective To study the feasibility and security of a new method by injecting potassium chloride into the cardiac chamber of the fetuses in second and third trimester pregnancy termination with central placenta previa. Methods A total of 18 women with central placenta previa for pregnancy termination at 18-33 weeks of gestation were recruited. They were treated with ultrasound-guided fetal cardioceniesis by injecting 10% potassium chloride into the cardiac chamber and intra amniotic injection of ethacridine lactate. Results Vaginal delivery was successful in all 18 cases. The mean time of labor induction was 27 h 12 min,and the mean time of birth process was 7 h 19 rain. The mean blood loss was 265 mL. None of the 18 patients had postpartum hemorrhage. Conclusion The use of potassium chloride injection by ultrasound-guided fetal cardiocentesis is a safe,convenient and effective method for termination of pregnancy in the second- and third-trimester with central placenta previa.
