228例老年鲍曼不动杆菌肺部感染的临床分析

Clinical analysis of 228 old patients with pulmonary infection caused by acinetobacter baumannii

目的了解老年鲍曼不动杆菌肺部感染的临床特点。方法分析228例老年鲍曼不动杆菌肺部感染患者的症状、体征、肺部影像学改变、细菌耐药现状及治疗转归等。结果老年鲍曼不动杆菌肺部感染多于基础疾病的危重期起病。临床症状和体征缺乏特征性。肺部X线影像学变化以小片状浸润影多见(占84.2%)。鲍曼不动杆菌对常用抗生素的耐药率为5.2%～86.3%。患者住院病死率为19.7%。结论临床上应重视鲍曼不动杆菌所引起的老年肺部感染。

Objective To investigate the clinical characteristics of pulmonary infection caused by acinetobacter banmannii. Methods The data of 228 old patients with pulmonary infection due to aeinetohacter baumannii were reviewed. The symptoms, physical signs, X-ray imaging of chest and sputum culture and drug sensitivity test and the effect of the treatment were studied. Results Pulmonary infection caused by acinetobacter banmarmii in the old patients were mostly seen at critical stage of the basic disease. There were nonspecific symptoms and physical signs. Most X-ray imaging of chest showed small opacity（84. 2% ）. The acinetobacter strains were identified through sputum culture to he resistant to antibiotics, and the drug resistance rate were ranging from 5.2% to 86. 3%. The case fatality rate was 19.7%. Conclusion Pulmonary infection caused by acinetobacter baumannii in the old patients must be taken into account.
