重症监护室严重脓毒症患儿死亡危险因素分析

目的 探讨儿童重症监护室(PICU)严重脓毒症患儿死亡的危险因素.方法 对我院PICU 80例严重脓毒症患儿,应用巢式病例对照研究方法进行分析,研究因素包括一般生物学特征、生命体征、基础疾病、感染部位、并发症、治疗措施等22个变量,做单因素分析,并采用Logistic回归进行多因素分析.结果 严重脓毒症患儿病死率为47.50%(38/80),基础疾病以先天性心脏病最多,革兰阴性杆菌感染为主,48.75%合并急性呼吸衰竭,42.50%并发脓毒性休克.脓毒症伴1、2、3及＞3个器官功能衰竭病死率分别为12.00%、52.60%、66.70%及71.40%.存活组和死亡组患者舒张压、平均动脉压、毛细血管再充盈时间、24 h尿量、pH值、血清乳酸、肺部感染、尿路感染、合并休克、多器官功能衰竭(MODS)受累脏器、国内小儿危重病例评分(PCIS)比较,差异均有统计学意义(P＜0.05).多元Logistic回归分析显示,MODS受累脏器、平均动脉压、24 h尿量、血清乳酸、PCIS是严重脓毒症患儿死亡的危险因素(P＜0.05).结论 儿童严重脓毒症病死率高,MODS、平均动脉压和24 h尿量下降、血清乳酸增高、PCIS＜70分是疾病死亡的危险因素.

Risk Factors Associated with the Death of Childhood Severe Sepsis in PICU

Objective To investigate risk factors associated with the death of pediatric severe sepsis in pediatric intensive care unit(PICU)with the hope to improve prognosis and decrease mortality. Methods A nest case control study was employed and 80 patients in PICU diagnosed as severe sepsis were enrolled from Jan 2005 to Jan 2010.Two variables such as general biotic characteristics,biochemical indices,underlying disease,infected site,clinical signs,and therapeutic approaches were included in both univariate and m...
