Abstract:
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.
