目的探讨自控硬膜外腔阻滞镇痛用于瘢痕子宫中期妊娠无痛引产的有效性和安全性。方法选择130例瘢痕子宫中期妊娠引产孕妇为观察组,同期不用任何镇痛措施的130例瘢痕子宫中期妊娠引产孕妇为对照组,比较两组孕妇引产时间、疼痛程度、产后出血量及产后尿潴留、瘙痒等并发症发生率的差异。结果观察组引产时间明显短于对照组,疼痛程度低于对照组,产后出血量少于对照组,差异均有统计学意义(P<0.05),两组均无子宫破裂等严重并发症发生,而产后皮肤瘙痒、尿潴留发生率比较,观察组较对照组高,差异具有统计学意义(P<0.05);观察组排胎时及排胎后血压、心率差异均无统计学意义(P>0.05),对照组排胎时及排胎后血压、心率均显著升高(P<0.05)。结论自控硬膜外腔阻滞镇痛应用于瘢痕子宫中期妊娠引产安全有效,同时还能缩短产程、减少子宫出血。
Objective To investigate the effectiveness and safety of self-controlled epidural block analgesia in the induction of painless induced abortion in mid-term hypertensive scar. Methods 130 pregnant women with induced uterine pregnancy were selected as the observation group and 130 pregnant women with induced uterine bleeding during the same period without any analgesic measures were selected as the control group. The duration of induced labor, pain, postpartum hemorrhage and postpartum urinary retention , Itching and other complications of the difference. Results In the observation group, the induction of labor was significantly shorter than that of the control group, the pain was lower than that of the control group, and the amount of postpartum hemorrhage was less than that of the control group (P <0.05). No severe complications such as uterine rupture occurred in both groups. The incidence of pruritus and urinary retention in postpartum skin was significantly higher in the observation group than in the control group (P <0.05). There was no significant difference in the blood pressure and heart rate between the control group and the control group (P> 0.05). Blood pressure and heart rate were significantly increased in the control group after rowing and after rowing (P <0.05). Conclusion The controlled epidural block analgesia is safe and effective in induction of labor during the second trimester of scar uterus. At the same time, it can shorten the labor process and reduce the uterine bleeding.
