摘要
目的探讨麻醉机通气系统细菌污染与全麻患者术后肺部感染的相关性,以控制患者术后呼吸道感染的发生。方法选取2012年6月-2013年6月进行全麻的238例手术患者为观察对象,观察麻醉机通气系统细菌污染与患者术后肺部感染的相关性;术前对使用的麻醉机采样后进行细菌培养,以是否被细菌污染进行分组,分为污染组和未污染组,比较两组患者术后肺部感染情况。结果共对麻醉机进行采样238台次,细菌培养阳性21台次,阳性率8.82%;对通气系统中吸气端、呼气端、钠石灰和气管导管共进行采样952件次,细菌培养结果中,凝固酶阴性葡萄球菌阳性16件次,阳性率为1.68%,为主要污染菌;通气系统中气管导管污染18件次,占1.89%,为主要受污染部件;238例患者中术后发生肺部感染13例,感染率5.46%;其中术前麻醉机污染组患者术后肺部感染11例,发生率为52.38%,明显高于未污染组的0.92%,两组比较差异有统计学意义(χ2=88.48,P<0.05);术前麻醉机污染与术后肺部感染存在相关性(r=0.64,P<0.05)。结论麻醉机通气系统细菌污染与全麻患者术后肺部感染存在相关性,对麻醉机通气系统进行消毒处理有助于控制患者术后呼吸道感染的发生。
OBJECTIVE To analyze the correlation of pollution of ventilation system in anesthesia machine and post-operative pulmonary infection in patients after general anesthesia ,so as to control postoperative respiratory tract infection .METHODS Totally 238 patients undergoing general anesthesia surgery from Jun .2012 to Jun .2013 were selected as the observation subjects ,then the correlation of bacterial contamination in ventilation system of anes-thesia machine and postoperative pulmonary infection were analyzed .Samples were collected from the anesthesia machine before operation for bacterial culture and the patients were divided into the contamination group and the non-contamination group according to the situation of bacterial contamination .The status of pulmonary infection after operation was compared between the two groups .RESULTS The total sampling times to the anesthesia ma-chine was 238 times ,including 21 positive times of germiculture ,the positive rate was 8 .82% .The total sampling times to the aspiration end ,the expiration end ,sode lime and the endotracheal tube of the ventilation system was 952 times ,including 16 positive times of coagulase-negative Staphylococcus which was the main contaminated bac-teria ,the positive rate was 1 .68% .There were 16 times of endotracheal tube pollution in the ventilation system which was the main contaminated parts ,accounting for 1 .89% .Of the 238 patients ,13 had pulmonary infection , the incidence was 5 .46% .There were 11 cases of patients with postoperative pulmonary infection in the group of preoperative contamination of anesthesia machine ,the incidence was 52 .38% ,which was significantly higher than 0 .92% in the non-contamination group （χ2 = 88 .48 ,P〈 0 .05） .Preoperative anesthesia machine pollution and postoperative pulmonary infection had correlation （r= 0 .64 , P〈 0 .05） .CONCLUSION Preoperative anesthesia＆amp;nbsp;machine pollution had correlation with postoperative pulmonary infection in patients after general anesthesia .Dis-infect
