目的探讨经阴道彩超判断孕囊着床部位对早孕人工流产手术的指导价值。方法选取2015年4月—2016年12月行人工流产的早孕妇女260例,随机分为观察组与对照组。观察组术前经阴道彩超查找孕囊着床部位的滋养层动脉,标明着床位置,按常规人工流产手术操作。对照组按常规人工流产手术操作。记录两组手术时间、术中出血量、恢复月经时间;比较两组术后并发症发生情况。手术时间、术中出血量、恢复月经时间比较采用t检验,并发症发生率比较采用χ~2检验,P<0.05为差异有统计学意义。结果观察组手术时间、月经恢复时间[(5.10±1.07)min、(29.06±10.73)d]比对照组[(7.91±1.54)min、(36.25±9.41)d]短,术中出血量[(11.94±5.90)ml]比对照组[(24.01±7.72)ml]少,比较差异有统计学意义(均P<0.05)。观察组人工流产不全发生率(0)低于对照组(4.62%),比较差异有统计学意义(P<0.05)。两组阴道炎、盆腔炎发生率比较差异无统计学意义(均P<0.05)。结论人工流产术前采用阴道彩超判断孕囊着床部位,可缩短手术时间及月经恢复时间,减少术中出血量,降低并发症发生率。
Objective To investigate the value of transvaginal color Doppler ultrasound in the determination of gestational sac implantation site for early pregnancy induced abortion. Methods 260 pregnant women with abortion from April 2015 to December 2016 were randomly divided into observation group and control group. Observation group preoperative vaginal ultrasound to find gestational trophoblast implantation site, marked the location of the bed, according to conventional abortion operation. Control group according to conventional abortion operation. The operation time, intraoperative blood loss and menstrual period were recorded. Complications of the two groups were compared. Operation time, intraoperative blood loss, recovery of menstrual time compared with t test, the incidence of complications compared with χ ~ 2 test, P <0.05 for the difference was statistically significant. Results The operative time and the recovery time of the menstruation in the observation group were shorter than those in the control group [(5.10 ± 1.07) min, (29.06 ± 10.73) d] [(7.91 ± 1.54) min and (36.25 ± 9.41) d] 11.94 ± 5.90) ml] than the control group [(24.01 ± 7.72) ml], with statistical significance (all P <0.05). The incidence of induced abortion (0) in the observation group was lower than that in the control group (4.62%), with significant difference (P <0.05). The incidence of vaginitis and pelvic inflammatory disease in the two groups showed no significant difference (all P <0.05). Conclusions The use of vaginal ultrasound before vaginal ultrasound to determine gestational sac implantation site, can shorten the operation time and menstruation recovery time, reduce intraoperative bleeding and reduce the incidence of complications.
