目的:探索不同内径医用导管用不同的放置方法,经甲醛熏蒸消毒效果比较,获得准确的理论参数,为临床应用提供更科学的依据。方法:将不同内径的清洁导管管腔内注入大肠杆菌活菌液后吹干,分别按平放法和竖立法,用甲醛熏蒸消毒,取消毒好的导管中段5cm 放于肉汤培养基内,在36℃恒温箱内孵育48小时,对阳性结果进行细菌学鉴定。结果:A 组,竖立法灭菌阳性率为19%,平放法灭菌阳性率为67%;B 组,竖立法灭菌阳性率为0,平放法灭菌阳性率为50%;C 组,导管内径大,灭菌效果好,反之,灭菌效果差。结论:灭菌效果竖立法优于平放法,灭菌的阳性率与导管内径的大小有关。
OBJECTIVE: To explore different placement methods of medical catheters with different internal diameters, to obtain accurate theoretical parameters by comparison of formaldehyde fumigation and disinfection effects, and to provide a more scientific basis for clinical application. Methods: The different diameter of the catheter clean lumen into E. coli live bacilli after drying, respectively, according to the laying method and the erection of law, fumigation with formaldehyde disinfection, remove the poisonous catheter middle 5cm placed in the broth medium, Incubation in a 36 ℃ incubator for 48 hours, the positive results were bacteriological identification. Results: In group A, the positive rate of erection was 19% and the positive rate of plaque sterilization was 67%. In group B, the positive rate of erection was 0 and the positive rate of plaque was 50%. In group C, Group, the catheter diameter, sterilization effect is good, on the contrary, sterilization is poor. Conclusion: The erect method of sterilization effect is better than that of flat method. The positive rate of sterilization is related to the diameter of catheter.
