【摘要】：目的研究妇产科手术患者不同麻醉时点麻醉用品的微生物污染状况。方法选择2014年5月-2015年5月医院收治的60例妇产科手术患者,对手术所用麻醉仪器实施采样,采样点为螺纹管接口、氧气流量调节钮、静脉三通旋转阀、麻醉机呼出气入口和麻醉机呼吸回路氧气入口,对60例手术患者于时点1(麻醉前)、时点2(麻醉10min后)、时点3(麻醉2h后)实施采样,共采集900份样本;对样本进行细菌培养,观察细菌培养结果,统计不同麻醉时点细菌分布状况及切口感染的感染率;采用SPSSl6.0软件对数据进行统计分析。结果时点1静脉三通旋转阀的采样无细菌生长,时点2检验出46份阳性,合格率为23.3%,时点3检验出60份阳性,均不合格,其余4个采样点各个时点的细菌数均在合格范围内;60例妇产科患者手术切口感染8例,切口感染率为13.3%;各个时点细菌构成中,占比最大的是凝固酶阴性葡萄球菌,其次为棒杆菌属。结论随着麻醉时间的不断延长,妇产科手术患者发生微生物污染的概率明显增加,在麻醉过程中,具有致病微生物污染,导致切口感染的危险,应建立相关的监督机制,落实感染控制的相关措施,从而减少因麻醉导致的医院感染的发生。
[Abstract]:Objective to study the microbial contamination of anesthetic products at different time points in patients undergoing gynecology and obstetrics surgery. Methods from May 2014 to May 2015, 60 patients with gynecology and obstetrics surgery were selected. The anesthetic instruments used in the operation were sampled. The sampling points were threaded tube interface, oxygen flow adjusting knob, and three-way venous rotary valve. The exhalation inlet of anaesthesia machine and the oxygen inlet of the breathing loop of anesthesis-machine were sampled at 1 hour (before anaesthesia, 2 hours after anaesthesia) and 3 (2 hours after anesthesia), and a total of 900 samples were collected, and the samples were cultured by bacteria. The results of bacterial culture were observed and the distribution of bacteria and the infection rate of incision infection were calculated at different anesthetic points. The data were analyzed by SPSSl6.0 software. Results there was no bacterial growth in the sampling of the three-way valve at time point 1, 46 samples were positive at point 2, the qualified rate was 23.3and 60 samples were positive at time point 3, all of them were unqualified. The number of bacteria at each time point in the other 4 sampling points were all within the eligible range of 60 patients with gynecology and obstetrics, 8 cases were infected by incision, and the infection rate of incision was 13.3.The bacterial composition of each time point was the largest proportion of coagulase negative staphylococci. The next is the genus Corynebacterium. Conclusion with the prolongation of anesthesia time, the probability of microbial contamination in patients undergoing gynaecology and obstetrics surgery is obviously increased. Implement infection control measures to reduce nosocomial infection caused by anesthesia.
