【Abstract】 Objective To investigate the clinical characteristic of pulmonary infection in the elderly patients,so that instruct to make a diagnosis and give treatment.Methods Look back to analyze 189 cases of pulmonary infection in the elderly patients in contrast with 216 cases of adult group.Results The percentage of elderly with a fever was 59.79% contrasted with the adult percentage of 93.98%(P<0.01),nonspecific symptoms in the early stage in the elderly group was 41.26% contrasted with the adult of 39.09%(P<0.05),repsiratory failure combined with the elderly was 38.01% contrasted with the adult of 0.29%(P<0.01),accompanied other disease of the elderly was 19.57% and it occurred in the adult was 3.70%(P<0.01),over two times infections occurred in the elderly was 14.28% with the adult of 1.39%(P<0.01),mortality among the elderly group was 29.10% contrasted with the 1.39% among thd adult (P<0.01).Conclusions These dangerous factors of subclinical symptoms,respiratory failure,accompanied diseases,complications,hospital acquired infections,over two times infections and mortality of pulmonary infections in the elderly group are very higher than that in the adult group.更多还原
