目的探讨剖宫产早孕妇女在氧化亚氮无痛人流术前应用卡孕栓扩张宫颈的临床效果。方法将自愿要求无痛人流术的剖宫产妇女随机分为二组,观察组术前2h阴道后穹窿放置卡孕栓0.5mg,对照组不用任何药物。术中探测并记录宫颈内口直径、出血量、手术持续时间及手术并发症等情况。结果观察组宫颈松弛度明显大于对照组(P<0.01),手术失败率明显减少(P<0.05),手术时间及出血量均明显减少。二组镇痛效果及手术并发症差异无统计学意义。结论剖宫产术后早孕妇女行氧化亚氮无痛人流术前阴道后穹隆放置小剂量卡孕栓可以有效扩张宫颈,缩短手术时间,减少出血量,提高手术成功率。
Objective To investigate the clinical effect of caesarean suppository dilatation of cervix in women with early cesarean section before painless abortion of nitrous oxide. Methods Women with cesarean section who volunteered to have painless abortion were randomly divided into two groups. The observation group received 0.5 mg of carbamazepine 2 hours before the posterior vaginal fornix in the observation group, without any medication in the control group. Intraoperative detection and recording of cervical mouth diameter, amount of bleeding, duration of surgery and surgical complications and so on. Results The cervical relaxation of the observation group was significantly greater than that of the control group (P <0.01), and the failure rate of operation was significantly decreased (P <0.05). The operation time and bleeding volume were significantly decreased. There was no significant difference in analgesic effect and operative complications between the two groups. Conclusions In early pregnancy after cesarean section, the painless nitrous oxide before vaginal posterior vaginal fornix placed in small doses of carbamazepine can effectively expand the cervix, shorten the operation time, reduce the amount of bleeding and improve the success rate of surgery.
