摘　　要：目的:探讨老年机械通气患者气管内导管生物被膜的形成状况,明确相关性和危险因素。方法:分析22例老年患者的25个气管导管各留置时间段与细菌培养结果。结果:25个气管导管细菌培养阳性22个,占88%,培养阴性的3个,占12%。结论:细菌密度与气管插管时间密切相关,随着插管时间的延长,细菌计量明显增加。Objective To investigate the status of biological membrane （biofilm） formation in the bronchi of old patients treated with mechanical air, and clarify its correlations and risk factors. Methods The retaining time in 25 bronchi from 22 cases of old patients and the results of bacterial culture were analyzed. Results Bacteria culture-positive samples are 22 cases isolated from 25 endotrached tube, accounting for 88%.Negative samples are 3 cases, accounting for 12%. Conclusion The density of bacteria is corresponding to the time of tubing in the bronchi. With the extension of tubing time, the quantity of bacteria is greatly increased.
