摘要
目的:讨论麻醉机通气污染与全麻术后肺部感染的临床研究。方法:将100例全麻手术患者纳入本次研究作为观察对象开展回顾性研究分析。术前对麻醉机通气系统进行取样、细菌培养,而后观察术前麻醉机通气系统取样后细菌培养结果、麻醉机通气污染与未污染状态下全麻术后肺部感染发生率。结果:100台麻醉机中共存在麻醉机污染例数为17例。100台麻醉机各通气系统取样后共完成400次细菌培养后有35例细菌培养阳性,以气管导管细菌培养阳性率最高,达到18%。35例细菌培养阳性中以凝固酶阴性葡萄球菌发生率最高,达到15%。100例全麻手术患者术后肺部感染发生共10例,发生率为10%。17例污染组肺部感染发生率41.18%明显高于83例未污染组的肺部感染发生率3.61%,差异有统计学意义(P<0.05)。结论:麻醉机通气污染将增加全麻术后肺部感染发生机率,应做好消毒灭菌工作,以有效规避该术后并发症。
Objective:To discuss the clinical study of ventilation pollution of anesthesia machine and pulmonary infection after general anesthesia.Methods:100 patients undergoing general anesthesia surgery were included in this study as the observation object to carry out retrospective research and analysis.The ventilation system of anesthesia machine was sampled and cultured before operation,and then the results of bacterial culture after sampling the ventilation system of anesthesia machine before operation,the incidence of pulmonary infection after general anesthesia in polluted and uncontaminated ventilation of anesthesia machine were observed.Results:There were 17 cases of anesthesia machine pollution in 100 anesthesia machines.35 cases were positive after 400 times of bacterial culture after sampling in each ventilation system of 100 anesthesia machines,and the positive rate of bacterial culture in tracheal catheter was the highest,reaching 18%.Among 35 cases with positive bacterial culture,coagulase-negative staphylococci had the highest incidence,reaching 15%.There were 10 cases of postoperative pulmonary infection in 100 patients undergoing general anesthesia surgery,and the incidence rate was 10%.The incidence of pulmonary infection in 17 cases of pollution group(41.18%)was significantly higher than that in 83 cases of non-pollution group(3.61%),and the difference was statistically significant(P<0.05).Conclusion:Ventilation pollution of anesthesia machine will increase the incidence of pulmonary infection after general anesthesia,and disinfection and sterilization should be done well to effectively avoid postoperative complications.
