目的:观察手动和电动负压吸引器终止早孕的临床效果。方法:将妊娠35~60d要求人工流产的妇女随机分为两组,观察组880例,使用手动负压吸引器(手动组);对照组800例,使用电动负压吸引器(电动组),两组均不采用任何镇痛方法,仅给予心语疏通服务。观察两组手术时间、术中出血量、疼痛程度、人工流产综合反应发生率、术后离站时间及人工流产不全发生率。结果:术中出血量、手术时间和流产不全发生率两组比较,差异均无统计学意义(P>0.05)。疼痛程度手动组轻于电动组(P<0.01);人工流产综合反应发生率手动组低于电动组(P<0.05);术后离站时间手动组短于电动组(P<0.01)。结论:手动负压吸引术具有安全有效和术时疼痛程度轻和术后离站时间短等优点,有较好的临床应用前景。
Objective: To observe the clinical effect of manual and electric vacuum aspirator termination of early pregnancy. Methods: The women who had induced abortion from 35 to 60 days of gestation were randomly divided into two groups. The observation group was 880 cases with manual negative pressure aspirator (manual group) and the control group with 800 patients with electrodynamic negative pressure aspirator The two groups did not use any analgesic method, only to give heart language to clear service. The operation time, intraoperative blood loss, degree of pain, the incidence of induced abortion, the time of postoperative departure and the incidence of induced abortion were observed. Results: There was no significant difference between the two groups in the amount of blood loss, operation time and incomplete abortion (P> 0.05). The pain rate of manual group was lighter than that of motorized group (P <0.01). The incidence of induced abortion in manual group was lower than that of motorized group (P <0.05). The time of leaving station was shorter than that of motorized group (P <0.01). Conclusion: Manual negative pressure aspiration has the advantages of safety and effectiveness, less pain during operation and less time after leaving operation, which has a good clinical application prospect.
