目的探讨高危妊娠人工流产术术前阴道放置卡孕栓、术中静脉麻醉和超声监测的临床疗效。方法 300例妊娠6~10周自愿要求行人工流产术的孕妇,随机分为两组,各150例,观察组:术前6h禁食水,术前2 h阴道后穹窿放置卡孕栓0.5 mg,术中实施超声监测和静脉麻醉下无痛人工流产术。对照组常规行人工流产术。比较两组临床疗效。结果观察组在宫口松弛情况、宫缩情况、术中出血量、手术时间、疼痛程度以及手术并发症等方面均明显好于对照组,差异具有统计学意义(P<0.05)。结论在高危人工流产手术时,术前2 h阴道内放置卡孕栓0.5 mg,术中行静脉麻醉和超声监测,可使宫颈软化扩张明显,增强子宫收缩,术中出血少、手术时间短、患者无痛、动态观察吸宫过程及宫腔内的情况,有效避免手术并发症的发生,降低手术风险,减轻患者痛苦。
Objective To investigate the clinical effect of preoperative vaginal placement of carbapet suppository, intraoperative intravenous anesthesia and ultrasonography in the treatment of high risk pregnancy induced abortion. Methods 300 pregnant women with voluntary pregnancy induced abortion at 6-10 weeks of gestation were randomly divided into two groups of 150 cases each. The observation group was given 6 hours preoperative water fasting, and 2 hours preoperative vaginal posterior fornix 0.5 mg , Intraoperative ultrasound monitoring and intravenous anesthesia painless abortion. Control group routine abortion abortion. The clinical efficacy of the two groups were compared. Results The observation group was significantly better than the control group in cervix relaxation, uterine contraction, intraoperative blood loss, operation time, pain and surgical complications, the difference was statistically significant (P <0.05). Conclusions In high-risk abortion, intrauterine injection of carbamazepine 0.5 mg intravaginally for 2 h before operation, intravenous anesthesia and ultrasound monitoring during operation can significantly improve cervical softening, increase uterine contractions, reduce intraoperative bleeding and short operative time. Patients Painless, dynamic observation of the process of suction and intrauterine conditions, effectively avoiding the occurrence of surgical complications, reduce surgical risk and reduce patient pain.
