摘要
目的了解经口气管插管的全身麻醉患者气管导管前端细菌污染情况。方法收集在全身麻醉下行手术治疗的92例患者临床资料,根据插管留置时间分为4组,每组23例,其中Ⅰ组插管留置时间≤60 min;Ⅱ组60 min<插管留置时间≤120 min;Ⅲ组120 min<插管留置时间≤180 min;Ⅳ组插管留置时间>180 min。术后收集气管导管前端标本并进行细菌培养,统计菌落数,比较4组患者导管前端的菌落数。结果 92例患者导管前端均培养出病原菌,例数最多为表皮葡萄球菌,其次是黄杆菌和铜绿假单胞菌。Ⅲ组及Ⅳ组的菌落数均高于Ⅰ组及Ⅱ组(均P<0.05)。术后有2例患者出现肺部感染,均为手术时间长于2 h的患者。结论行全身麻醉后的患者其气管插管前端均有一定的菌落数,插管留置时间长于2 h的患者菌落数明显增加。
Objective To investigate the bacterial contamination status at the endotracheal catheter front-end in patients receiving orotracheal intubation under general anesthesia. Methods The clinical data of 92 patients receiving surgical procedure under general anesthesia were collected,the patients were divided into four groups according to the duration of intubation and catheter indwelling,with 23 cases in each group,including group Ⅰ(duration of intubation and catheter indwelling≤60 minutes),group Ⅱ(60 minutes<duration of intubation and catheter indwelling≤120 minutes), group Ⅲ(120 minutes<duration of intubation and catheter indwelling≤180 minutes) and group Ⅳ(duration of intubation and catheter indwelling>180 minutes).After operation,samples were collected from the endotracheal catheter front-end for bacterial culture and colony-forming units counting,then colony-forming units at the endotracheal catheter front-end were compared among the four groups. Results Pathogens were detected in the cultured samples from the endotracheal catheter front-end in the 92 patients,dominated by Staphylococcus epidermidis which was followed by Flavobacterium and Pseudomonas aeruginosa .Groups Ⅲ and Ⅳ had higher colony-forming units than groups Ⅰ and Ⅱ(all P <0.05).Two cases suffered from pulmonary infection after operation,and both had a operation duration more than 2 hours. Conclusion Patients under general anesthesia report a certain colony-forming units at the endotracheal catheter front-end,those with a duration of intubation and catheter indwelling more than 2 hours present significantly increased colony-forming units.
