手动负压吸引术用于人工流产的临床效果

Clinical observation of manual vacuum aspiration in induced abortion

目的:观察手动负压吸引术(MVA)用于早期人工流产的临床效果。方法:选择2018年1-9月于本院自愿行人工流产术且停经时间≤56d的妇女200例,依照入院顺序分为两组各100例,分别实施电动负压吸引术(EVA)和MVA,观察两组手术情况。结果:MVA组手术时间、术中出血量、扩张宫颈率、使用刮匙率分别为(3.5±1.2)min、(5.8±0.6)ml、7.0%和5.0%,均少于EVA组的(5.1±1.1)min、(13.2±1.3)ml、100.0%和18.0%(P<0.05);进出宫腔1次、2次、3次的比率MVA组分别为65%,35%,0,低于EVA组的10%,62%,28%(P<0.05);MVA组VAS疼痛评分为(4.2±1.4)分,低于EVA组的(5.4±1.2)分(P<0.05)。结论:MVA终止早期妊娠能够显著缩短手术时间,减少术中出血量,降低扩张宫颈率和使用刮匙率,减少进出宫腔次数,减轻术中疼痛,值得临床应用。

Objective:To observe the clinical effect of manual vacuum aspiration(MVA)in early induced abortion.Methods:200 pregnant women with less than or equal to 56 gestational days who voluntarily required abortion were divided into two groups according to the order of admission from January 2018 to September 2018.100 women in electric vacuum aspiration(EVA)group were given abortion by EVA,and 100 women in MVA group were given abortion by MVA.The operation situation of women were observed.Results:The operation time,intraoperative bleeding volume,cervical dilatation rate,rate of curette used of women in EVA group were 3.5±1.2 min,5.8±0.6 ml,7.0%,and 5.0%,respectively,which were significant less than those(13.2±1.3 ml,5.1±1.1 min,100.0%,and 18.0%,respectively)of women in EVA group(P<0.05).The rate of uterine cavity got in and out for once,2 times,and 3 times of women in the EVA group were 65%,35%,and 0%,respectively,which were significant lower than those(10%,62%,and 28%,respectively)of women in EVA group(P<0.05).The VAS pain score(4.2±1.4 points)of women in MVA group was significant lower than that(5.4±1.2 points)of women in EVA group(P<0.05).Conclusion:MVA for early abortion can significantly shorten the operation time,reduce intraoperative bleeding volume,decrease the rate of cervical dilatation and the curette used,reduce the times of uterine cavity got in and out,and relieve pain,which is worthy of clinical promotion.
