老年糖尿病医院获得性下呼吸道感染病原学与危险因素分析

Analyzing pathogenic and risk factors of hospital acquired lower respiratory-tract infection in elderly diabetics

目的 提高对老年糖尿病医院获得性下呼吸道感染的认识 ,探讨其有效的防治措施。方法 总结老年糖尿病 196例和其中发生医院获得性下呼吸道感染者 6 8例次的临床资料 ,分析其发生感染的病原学情况、细菌的耐药率和血糖控制情况、住院天数、并发症等危险因素与糖尿病发生院内下呼吸道感染的关系。结果 ①病原菌以G-杆菌为主 ,细菌耐药及二重感染相当严重。②高血糖、高糖化血红蛋白、住院时间长及伴有并发症的糖尿病患者并发感染明显增多。结论 积极控制血糖 ,治疗并发症 ,缩短住院时间 ,重视病原学监测 。

Objective To study the risk factors of hospital acquired lower respiratory-tract infection in elderly diabetics. Methods 68 in 196 case of elderly diabetics. developing hospital acquired lower respiratory tract infection in the past three years were summarized. The relationship between the risk factors(pathogen, bacterial resistant rate, blood glucose level, glucosylated hemoglobin, days in hospital and complications) and the incidence of lower respiratory-tract infection in diabetic was analyzed. Results ①Gram-negative bacilli were in the major pathogens. Bacterial resistance and double infection were common. ②Diabetics with high blood glucose level, high glucosylated hemoglobin, long hospital stay and complication had increased infection rate. Conclusion Blood glucose control, treatment of complication, shortening hospital stay, pathogenic examination and proper use of antibiotics are important factors in prevention and treatment of hospital acquired lower respiratory-tract infection in elderly diabetics.
