目的：探讨老年患者败血症的危险因素，为临床预防提供依据。方法：收集2013年1-12月住本院败血症患者共42例，将其分为老年组28例，对照组14例，回顾性分析其病原菌情况、诱因，并对老年组与对照组进行比较，通过Logistic回归分析影响败血症患者预后危险因素。结果：老年组治愈12例，死亡16例，病死率为57.1%；对照组治愈8例，死亡6例，病死率为42.9%，两组病死率比较，差异无统计学意义。28例老年患者败血症共分离出41株病原菌，以G-菌为主。两组年龄、住院时间、呼吸系统疾病比较，差异有统计学意义（P<0.05），多因素Logistic回归分析显示住院时间是老年组败血症的独立危险因素（P<0.05）。结论：ICU内老年患者败血症预后受住院时间影响，对具备此高危因素的患者需加强监护。%Objective:To investigate the risk factors in elderly patients with sepsis, and provide basis for clinical prevention.Method: From January 2013 to December 2013 in our hospital,42 patients with sepsis were divided into the elderly group for 28 cases and in the control group for 14 cases, the pathogens, incentives were retrospectively analyzed between the two groups. Logistic regression analysis was adopted to analyze the risk factors of prognosis in patients with sepsis.Result: In the elderly group 12 cases were cured, 16 cases died, the mortality rate was 57.1%. In the control group 8 cases were cured, 6 cases died, the mortality rate was 42.9%, mortality rate between the two groups was not statistically significant (P<0.05). 28 elderly patients with sepsis were isolated 41 strains of pathogenic bacteria, G-dominated. Comparison between the two groups age, duration of hospitalization, respiratory diseases were statistically significant (P<0.05), multivariate logistic regression analysis showed that the time of hospitalization was independent risk factor of elderly sepsis group (P<0.05).Conclusion:ICU in elderly patients with septicemia prognostic effect by the hospitalization time, to have the high risk factors of the patients need to strengthen monitoring.
