目的探讨针对特殊早孕人群采用B超引导下无痛人流术的临床价值。方法随机选出2008年1月至2012年12月16～50岁孕40～60d,子宫发育不良(包括畸形)、多年带环后受孕、无阴道分娩史(包括未育及有子宫手术史)等,在本院门诊行无痛人流手术的妇女200名,采用B超引导下无痛人流术者100名作为观察组,直接行无痛人流术者100名作为对照组,(n=100),观察组妇女行无痛人流时手术医师与B超医师配合,直吸孕囊,孕囊消失宫腔线规则且术者感觉吸干净即术毕。对照组则按传统方法进行无痛人工流产。结果观察组操作时间短,出血少,术后并发症少,麻醉醒后患者痛苦明显减轻。结论 B超引导下进行无痛人工流产具有直观性,能动态观察手术器械进出宫腔情况,孕囊的具体位置,及时了解宫腔情况及吸刮是否干净,最大限度缩短手术时间,减轻患者痛苦及术后并发症,更人性化。 Objective To investigate the clinical value of painless abortion under the guidance of B-ultrasonography for the special population of early pregnancy. Methods From January 2008 to December 2012, 40 ~ 60 d pregnant women aged from 16 to 50 were randomly selected. Uterine dysplasia (including deformity), pregnancy after vaginal delivery for many years, history of vaginal delivery (including the history of non-fertility and uterine surgery) , 200 women with painless abortion in our clinic were recruited. 100 painless abortion patients under B-guided ultrasonography as observation group and 100 painless abortion patients directly as control group (n = 100) In the observation group, the painless surgeons combined with the B-type physician to direct the gestational sac and the gestational sac disappeared. The control group according to the traditional method of painless abortion. Results The observation group had short operation time, less bleeding, less postoperative complications and significantly less pain after anesthesia awakening. Conclusion B-guided artificial abortion is intuitive, and can dynamically observe the situation of surgical instruments entering and exiting the uterine cavity, the specific location of the gestational sac, timely understanding of the uterine cavity and whether the suction is clean, to minimize the operation time and reduce the suffering of patients And postoperative complications, more humane.
