目的研制一种结构简单,操作方便,安全有效的注药膨胀式扩宫棒。方法选取2008年10月至2009年10月进行取出和放置宫内节育器、人工流产时需要进行宫颈扩张的受术者648例。随机分为观察组和对照组,观察组322例,采用注药膨胀式扩宫棒;对照组326例,采用传统的的金属扩宫器。两组手术准备按常规处理。从宫颈松弛程度,术中疼痛程度及人流综合征发生率方面的资料进行统计分析,具有显著性差异(P<0.01)。结论注药膨胀式扩宫棒能有效避免对受术者宫颈及子宫多次局部刺激,减轻手术者痛苦,安全简便,效果满意,值得推广。
Objective To develop a simple structure, easy to operate, safe and effective injection expanding expander rod. Methods From October 2008 to October 2009 for removal and placement of IUD, 648 cases requiring cervical dilatation during abortion were included. Randomly divided into observation group and control group, the observation group of 322 cases, the use of drug expansion dilatation bar; control group of 326 cases, the use of the traditional metal dilator. The two groups were prepared for routine treatment. Statistical analysis was conducted on the data of cervical relaxation, degree of intraoperative pain and incidence of flow syndrome, with significant differences (P <0.01). Conclusion Infusion dilatation gonadectomy rod can effectively avoid multiple local stimulation on the subject’s cervix and uterus and relieve the pain of the surgeon. It is safe and simple, and satisfactory in effect. It is worth to be popularized.
