目的:探讨子宫内膜微型套管终止早早孕的临床效果。方法:将孕31-42d因非意愿妊娠要求终止妊娠的1267例孕妇随机分成A组(466例)、B组(418例)、C组(383例)。A组用子宫内膜微型套管代替常规金属吸管行人工流产手术;B组采用常规人工流产手术;C组予以米非司酮、米索前列醇配伍进行药物流产。观察比较各组患者疼痛程度、疼痛率、人流综合征发生率,术中出血量及术后阴道流血时间、流产情况。结果:A组疼痛程度、疼痛率均小于B组、C组,A组人流综合征发生率低于B组(P<0.01),完全流产率与B组相比无明显差异,但明显大于C组(P<0.01);且微型套管易于操作,术中出血量、术后阴道流血时间均明显小于/短于B组、C组(P<0.01)。结论:子宫内膜微型套管终止早早孕可减轻术中疼痛、人流综合征,手术易操作,术中出血少、术后流血时间短、费用低,值得临床推广使用。
Objective: To investigate the clinical effect of endometrial microcannula termination of early pregnancy. Methods: 1267 pregnant women with gestational age from 31-42d due to unwanted pregnancy were randomly divided into group A (466 cases), group B (418 cases) and group C (383 cases). A group of endometrial micro-cannula to replace the conventional metal pipette abortion abortion; Group B using conventional abortion; C group to mifepristone, misoprostol compatibility of medical abortion. The pain degree, pain rate, incidence of flow syndrome, intraoperative blood loss and postoperative vaginal bleeding time and abortion were observed and compared. Results: The pain rate and pain rate in group A were less than those in group B. The incidence of flow syndrome in group C and group A was lower than that in group B (P <0.01). The rate of complete abortion was not significantly different from that in group B Group (P <0.01). The mini-cannula was easy to operate. The amount of bleeding during operation and postoperative vaginal bleeding were significantly shorter than those in group B and C (P <0.01). Conclusions: Endometrial endometrial microendoscopy early termination of pregnancy can reduce intraoperative pain, flow syndrome, easy operation, less bleeding, shorter postoperative bleeding time, low cost, worthy of clinical promotion and use.
