摘要
目的研究ＳＩＣＵ患者ＮＰ相关的独立危险因素与年龄（老年组和非老年组）、ＮＰ发生率的关系。方法调查外科监护病房（ＳＩＣＵ）获得性肺部感染（ＮＰ）相关的独立危险因素，包括：基础疾病、休克、意识改变、慢性肺部疾病、机械通气的使用和持续时间、误吸、Ｈ２受体阻断剂的使用等在老年组患者（年龄≥６０岁）和非老年组患者（年龄＜６０岁）中分布情况及其ＮＰ发生率。结果４５２例ＳＩＣＵ患者中，老年组１９６例患者ＮＰ发生率２１．４％，非老年组２５６例患者ＮＰ发生率为１１．４％，老年患者ＮＰ发生率明显增高（Ｐ＜０．０１）。老年组患者平均机械通气使用时间长，ＮＰ的发生率高于非老年组患者（Ｐ＜０．０５），合并慢性肺部疾病的比例及ＮＰ发生率明显高于非老年组患者（Ｐ＜０．０１）。结论机械通气使用时间长、误吸多。
OBJECTIVE To evaluate distribution of independent risk factors for nosocomial pneumonia (NP) and incidence of NP in 196 geriatric and 256 non-geriatric cases of all continuous 452 patients admitted to surgical intensive care unit (SICU) were studied. METHODS Independent risk factors for NP include: underlying diseases, shock, depressed consciousness, mechanical ventilation (MV), large volume aspiration, the use of H 2 blockers with and without antacid and others. RESULTS Incidence of NP for geriatric patients was 21.4%, non-geriatric patients 11.4%. The mean MV duration in geriatric patients with high incidence of NP was longer than that in non-geriatic patients. Proportion of complication for chronic pulmonary disease and incidence of NP in geriatric patients were exceedingly higher than that in non-geriatric patients. Eleven of 42 geriatric patients developed to NP because of large volume aspiration, whereas only 2 of 30 non-geriatric patients developed too. CONCLUSION It is the longer duration for MV and more commonly large volume aspiration and higher complication for chronic pulmonary diseases in geriatric patients than that in non-geriatric patients that account for high incidence of NP in geriatric patients.
