摘要
目的 探讨肺心病患者院内肺炎的临床特点及其危险因素。方法 对 685例肺心病患者中的 5 6例院内肺炎情况进行了回顾性分析 ,在 IMP- PC计算机上用 FOXBASE+建立数据库 ,用 SAS软件进行统计。对院内肺炎的危险因素分别进行单因素和 Logistic多因素分析。结果 肺心病患者院内肺炎感染率为 8.2 %、死亡率为 3 3 .9%。主要病原菌为 G- 杆菌 (75 % ) ,其中以铜绿假单胞菌为主 ,其它依次为肺炎杆菌、大肠埃希菌等。结论 肺心病患者院内肺炎的临床表现不典型 ,诊断主要靠胸部 X线检查和深部痰细菌培养。昏迷时间≥ 5天、类固醇激素使用时间≥ 2 0天、气管切开和气管插管留置时间≥ 10天、广谱抗生素使用时间≥ 3 0天等是造成院内肺炎的主要危险因素。因此 。
OBJECTIVE To investigate the clinical characteristics and risk factors of nosocomial pneumoonia in patients with chronic cor pulmonale. METHOD A retrospective analysis on 56 cases suffered from nosocomial pneumonia in 685 cases with chronic pulmonary heart desease was made. RESULTS The infection rate of nosocomical pneumoonia in total 685 patients was 8.2% and the mortality was 33.9%. The ratio of G - bacilli to total bacteria examined was 75.0%,the bacilli were mainly Pseudomonas aeruginosa and the others in proper order were pneumobacillus, Escherchia coli, and so on. CONCLUSIONS The clinical features of nosocomial pneumonia in chronic pulmonary heart disease are usually untypical. Proper dignosis is mainly depending upon examination of the chest χ ray films and culture of bacteria in sputum from deep position. The risk factors are closely associated with the duration of coma (≥5days), time of using corticosteroids (≥20days), length of tracheotomy and intratracheal indwelling cannulation(≥10days) and time of using broad spectrum antibiotics(≥30days).
