为评价宫术安栓在人工流产术中的镇痛效果，研究了２００例早孕要求终止妊娠的患者（包括未产妇１２１例和经产妇７９例），随机分为宫术安栓组（Ａ组ｎ＝１００），安慰剂组（Ｂ组ｎ＝１００），观察两组的手术扩宫效果、术中疼痛程度、术后血压、脉搏变化及人流综合征等表现。结果显示：Ａ组未产妇扩张宫颈方面效果优于Ｂ组（Ｐ＜００１），两组术后血压、脉搏均较术前下降，但Ａ组血压（收缩压和舒张压），脉搏下降程度均小于Ｂ组（Ｐ＜００１）。Ａ组术中疼痛程度低于Ｂ组（Ｐ＜００１），出现人流综合反应（恶心、出冷汗）例数少于Ｂ组（Ｐ＜００５），出现呕吐例数则无显著差异（Ｐ＞００５），经产妇Ａ、Ｂ两组扩宫效果无明显差异（Ｐ＞０１０）。由此得出结论：宫术安栓在人工流产术中，具有明显的扩张宫颈、减轻疼痛、降低人流并发症的功效 To evaluate the analgesic efficacy of Miyazatsu suppository in abortion, 200 patients with premature termination of pregnancy (including 121 maternal and 79 maternal mothers) were studied and randomly assigned to GongShu’an suppository (group A) n = 100). The placebo group (n = 100 in group B) was enrolled in this study. The effect of expanding the operation, intraoperative pain, postoperative blood pressure, pulse rate and flow syndrome were observed in two groups. The results showed that in group A, the effect of non-maternal dilatation of cervix was better than that of group B (P <001). The postoperative blood pressure and pulse rate of both groups decreased compared with those before operation. However, the blood pressure (systolic and diastolic blood pressure) The degree of less than B group (P <0  01). The pain in group A was lower than that in group B (P <001). There were fewer cases of comprehensive reaction (nausea and cold sweat) in group A than those in group B (P <005), but there was no significant difference in vomiting (P> 005). There was no significant difference between the two groups (P> 010). Concluded from this: Palace surgery bolt suppository in the abortion, with significant expansion of the cervix, reduce pain, reduce the effectiveness of human flow
