老年肾衰竭透析患者合并感染的临床分析

Clinical investigation of infectious complications in chronic renal failure elderly patients undergoing hemodialysis

目的 探讨老年肾衰竭血液透析患者感染的临床特点、相关因素及防治对策。方法 回顾分析82例老年血液透析患者的感染部位、病原菌种类、营养状况、透析充分性、原发病等与感染的关系。结果 感染组 4 4例患者共发生感染 6 0例次 ,肺部感染和尿路感染最常见 ,其次为肠道感染及中心静脉置管处局部感染 ,感染组血红蛋白、血清白蛋白及营养状况较非感染组明显减低 ,透析时间 /周感染组较非感染组明显减少。结论 慢性肾衰血液透析患者感染发病率高 ,积极改善营养状况 ,加强透析 ,注意个人卫生习惯 ,有助于预防感染。

Objective To investigate the characteristic and possible risk factors of infection in elderly patients with chronic renal failure(CRF) undergoing hemodialysis.Methods The positions and etiologies of infetion,nutritional status,dialysis adequacy,causes of CRF were retrospectively analyzed in 82 CRF elderly patients undergoing hemodialysis.Results 60 times infection were observed among the 44 patients,pulmonary and urinary infection were the commonest.Intestinary and vascular access infection were secondary.Hemoglobin and serum albumin decrease obviously in infectious patients compared with the patients without infection.High incidence of infection in elderly patients was associated with poor nutritional states and dialysis inadequacy.Conclusion The prevalence of infection is high in dialysis elderly patients,improving nutritional status and adequate dialysis can contribute to prevent the infections.
