目的探讨B超引导下微管微创无痛人流术的临床疗效。方法调查2011年2月2012年8月自愿要求终止妊娠的患者183例,随机分为A组药物流产组(n=91)、B组传统负压吸引术组(n=91)和C微管微创组(n=91),A组采用米非司酮和米索前列酮联合用药,B组采用负压吸引术,C组采用微管微创人流手术。观察比较3组手术时间、出血量、疼痛、完全流产率以及患者是否出现人流综合征。结果 3组无痛率分别为12.09%、34.07%、91.21%,C组与A组、B组比较,有统计学差异(P<0.05)。3组完全流产率分别为91.21%、94.51%、97.80%,3组完全流产率无统计学差异(P>0.05);3组人流综合征发生率分别为1.32%、7.69%、3.30%,3组人流综合征发生率有统计学差异(P<0.05);C组手术时间短于A组和B组(P>0.05);C组术中出血量少于A组和B组(P>0.05)、C组术后出血天数短于A组和B组(P<0.05)。结论 B超引导下微管微创人流术具有无痛率高、手术时间短、人流综合征发生低等特点,是一种安全有效的人工流产方法,值得在临床上得到推广。
Objective To investigate the clinical effect of B-guided microtraulectomy on painless abortion. Methods A total of 183 patients who volunteered for termination of pregnancy in February 2011 and August 2012 were randomized into Group A (n = 91), Group B (n = 91), and C-microtubules In the minimally invasive group (n = 91), group A was treated with combination of mifepristone and misoprostone, group B with negative pressure aspiration, and group C with minimally invasive catheterization. The operation time, blood loss, pain, complete abortion rate and the incidence of flow syndrome in the three groups were observed and compared. Results The painless rates of the three groups were 12.09%, 34.07% and 91.21% respectively. There was a significant difference between group C and group A and B (P <0.05). The rates of complete abortion in the three groups were 91.21%, 94.51% and 97.80%, respectively. There was no significant difference in the rate of complete abortion among the three groups (P> 0.05). The incidences of the three groups were 1.32%, 7.69% and 3.30% (P <0.05). The operation time of group C was shorter than that of group A and B (P> 0.05). The intraoperative blood loss of group C was less than that of group A and B (P> 0.05) ), And the number of bleeding days in group C was shorter than that in group A and group B (P <0.05). Conclusion B-guided microtrauma minimally invasive abortion is a safe and effective method of abortion with high painless rate, short operative time and low incidence of human flow syndrome. It is worth to be popularized clinically.
