摘要
本文在５０例行肺切除术中，分别采集病肺、支气管切缘、健侧支气管内分泌物４５０份，做常规细菌和细菌Ｌ型培养及药敏试验。分离出需氧菌和真菌６０株，厌氧菌１２株、细菌Ｌ型４２株。菌群主要分布在病肺内约占５０％。需氧菌种中Ｇ＋球菌占６１．７％，葡萄球菌多见；其次Ｇ￣＋杆菌占２３．３％，以肠杆菌科细菌为主。厌氧菌占细菌型１６．７％。细菌Ｌ型特点与细菌型一致。围术期选择作用于细胞壁和细胞质的抗生素，以杀灭细菌型及细菌Ｌ型感染。
specimens of 50 patients underwent pulmonary resection were investigated samples of secretion were taken from three sites:the focus of resected lung,the bronchial cutoff point and the other intrabronchi.6 0 strains of aerobic bacteria and fungi,12 strains of anaerobic bacteria and 42 strains of L-form bacteria were isolated and 50%of these organisms were distributed in the focus of resected lungs.Among the aerobic bacterial strains,the gram positive cocci amounted to 61.7%and the staphylococci were cultured frequently,the gram negative bacilii occurred in 23.3%,especially the enterobacteriaceae species were discovered easier,The anaerobic bacteria were only 16.7%of the routine ones. The results revealed that L- form bacteria existed widespread in the lower respiratory tract.The perioperative antibiotics that could be combined act on cell wall and cytoplasm should be combined to act on cell wall, and cytoplasm should be chosen in order to disinfect both L-form bacteria and bacteria form in pulmonaty surgery
