两种麻醉机内部消毒方法对麻醉机细菌检出阳性率、呼吸道感染率的影响

Influence of Two Anesthesia Machine Internal Disinfection Methods on Positive Bacterial Detection Rate and Respiratory Infection Rate of Anesthesia Machine

目的比较两种麻醉机内部消毒方法对麻醉机细菌检出阳性率及呼吸道感染率的影响。方法以本院例行麻醉手术患者150例为研究对象,随机分为两组各75例。实验组予以消毒机消毒,传统组则予以含氯消毒液浸泡消毒。在消毒前、使用前、使用3天在呼吸回路处采样,计算细菌检出阳性率,并统计两组患者的呼吸道感染率。结果消毒前、使用3天,两组的麻醉机污染率比较无统计学意义(P>0.05)。使用3天,实验组的细菌检出阳性率为10.5%,低于传统组的19.1%(P <0.05)。实验组的肺部感染率3.8%,与传统组的5.3%比较无统计学差异(P>0.05)。结论对麻醉机予以消毒机及含氯消毒液浸泡消毒对预防呼吸道感染疗效相似,但前者更能有效降低麻醉机细菌检出阳性率,消毒效果较好。

Objective To compare the influence of two anesthesia machine internal disinfection methods on positive bacterial detection rate and respiratory infection rate of anesthesia machine. Methods 150 cases of patients undergoing anesthesia surgery in our hospital were randomly divided into two groups, with 75 cases in each group. The experimental group used disinfection machine for disinfection, while the traditional group was soaked and rinsed with chlorine-containing disinfectant. Samples were taken at the respiratory circuit before disinfection, before use and 3 days after use. The positive bacterial detection rate was calculated. The respiratory infection rates of two groups were statistically analyzed. Results Before disinfection and at 3 days after use, no statistical difference was found in the contamination rates of anesthesia machine between the two groups(P >0.05). At 3 days after use, the positive bacterial detection rate of the experimental group was 10.5%, lower than 19.1% of the traditional group(P <0.05). The lung infection rate of the experimental group was3.8%, had no statistical difference with 5.3% of the traditional group(P >0.05). Conclusions Disinfection machine and chlorine-containing disinfectant for anesthesia machine have the similar curative effects in the prevention of respiratory infection, but the former can more effectively reduce the positive bacterial detection rate in anesthesia machine, with better disinfection effect.
