对我院４年经病原学证实的５４例不动杆菌医院下呼吸道感染（ＡＮＲＩ）进行临床和实验室研究，结果表明，ＡＮＲＩ占医院感染构成比１．０９％，占下呼吸道感染分离菌株的１６．７％。其原发基础疾病中呼吸系统疾病居首位，占４０．７４％。调查发现，该菌对麻醉、呼吸道治疗器材污染严重，麻醉机罗纹管带菌率为１１．１１％、吸氧面罩４％、吸痰管４．４４％、吸痰管冲洗液１３．９５％，不动杆菌对青霉素、洁霉素耐药率高达１００％，其次头孢唑啉８７．７６％，氨苄青霉素８３．３３％。提出做好保洁工作、做好各种侵入性操作术前和术后护理，合理使用抗生素对降低ＡＮＲＩ的发病率是必要的。
Clinical and laboratory studies of 54 patients with Acinetobacter nosocomial lower respiratory tract infection (ANRI) confirmed by etiology in our hospital for 4 years showed that ANRI accounted for 1.09% of the total hospital infection, accounting for the total number of isolates of lower respiratory tract infection 16.7%. The primary underlying diseases in respiratory diseases ranked first, accounting for 40.74%. The survey found that the bacteria on the anesthesia, respiratory tract treatment equipment, serious pollution, anesthesia rib rib carrier rate of 11.11%, oxygen mask 4%, 4.44% suction tube, suction tube flushing fluid 13.95% Acinetobacter penicillin, lincomycin resistance rate as high as 100%, followed by cefazolin 87.76%, ampicillin 83.33%. Proposed to do a good job of cleaning work, do a variety of invasive operation preoperative and postoperative care, rational use of antibiotics to reduce the incidence of ANRI is necessary.
