目的 分析凶险性前置胎盘使用卡前列素氨丁三醇以及球囊压迫治疗作用。方法 选择实施凶险性前置胎盘治疗的66例患者为研究样本,研究时间均在2017年1月—2020年1月。采取随机数字排列表法将其分成常规组（33例）以及观察组（33例）,予以常规组纱布填塞以及卡前列素氨丁三醇治疗,予以观察组球囊压迫以及卡前列素氨丁三醇治疗,对比每组手术过程中、手术后2 h以及手术后24 h出血量;治疗总有效;止血时间以及住院时间。结果 观察组手术过程中、手术后2 h以及手术后24 h出血量均低于常规组（P<0.05）。观察组与常规组治疗总有效率依次是93.94%、75.76%（P<0.05）。观察组止血时间以及住院时间均短于常规组（P<0.05）。结论 凶险性前置胎盘病患采用球囊压迫以及卡前列素氨丁三醇治疗,可降低出血量,增强治疗效果,缩短止血时间以及住院时间,发挥一定临床应用作用。

Objective To analyze the effect of carboprost tromethamine plus balloon compression on pernicious placenta previa. Methods A total of 66 patients with pernicious placenta previa treated from January 2017 to January 2020 were selected as study subjects. According to random number table, the patients were divided into a routine group （33 cases） and a test group （33 cases）. The routine group took gauze packing and carboprost tromethamine; the test group took balloon compression and carboprost tromethamine. The bleeding volumes during surgery and after 2 h and 24 h of surgery, total effective rate, hemostasis time, and hospital stays were compared between the two groups. Results During surgery and after 2 h and 24 h of surgery, the bleeding volumes in the test group were significantly less than the volumes in the routine group （P<0.05）. The total effective rates in the test group and the routine group were 93.94% and 75.76% respectively, showing a significant difference （P<0.05）. The hemostasis time and hospital stays in the test group were shorter than those of the routine group （P<0.05）. Conclusion Balloon compression combined with carboprost tromethamine is effective in the treatment of pernicious placenta previa, as it can reduce bleeding volume, increase treatment effects, and shorten hemostasis time and hospital stays.
