本文报道14例慢性阻塞性肺病呼吸衰竭气管切开后,下呼吸道分泌物创面渗出液菌群检查的结果。分离所得均为鼻、口、咽部、皮肤正常菌群或病室环境中的常有菌种,如金黄色葡萄球菌、绿脓杆菌等。下呼吸道菌种可能是上呼吸道的正常菌群或气管切开创面菌种的下行播散,或由于器材消毒以及无菌操作技术不够严格导致交叉感染。病情稳定时,这些细菌可长期寄居于下呼吸道而并无危害,在不利条件下才增生繁殖导致肺部严重感染。结合资料分析,讨论了这些菌群的临床意义,并提出气管切开后防治下呼吸道感染的意见。
This article reports the results of 14 cases of chronic obstructive pulmonary disease respiratory failure tracheotomy, lower respiratory tract exudate wound exudate bacterial flora. Separation of the resulting nose, mouth, pharynx, normal skin flora or ward environment often strains, such as Staphylococcus aureus, Pseudomonas aeruginosa and so on. Lower respiratory tract bacteria may be the upper respiratory tract of normal flora or tracheostomy wound species down spread, or because of equipment sterilization and aseptic technique is not strict enough to cause cross-infection. When the disease is stable, these bacteria can be long-term residents in the lower respiratory tract and no harm, proliferate and multiply under adverse conditions lead to serious lung infection. Combined with data analysis, discussed the clinical significance of these bacteria, and put forward the opinion of prevention and treatment of lower respiratory tract infection after tracheostomy.
