儿童严重脓毒症死亡危险因素分析

目的 探讨儿童严重脓毒症死亡危险因素,以利于疾病早期认识和诊断,改善预后,降低病死率.方法对69例严重脓毒症患儿,应用巢式病例对照研究方法 进行分析,以患儿入院日为研究起点,死亡或出院为终点.研究因素包括年龄、性别、基础疾病、感染部位、病原菌、临床征象、并发症和治疗措施方面共24个变量,作单因素分析,并采用Logistic回归进行多因素分析,计算OR及其95%CI.结果 69例患儿中死亡31例,病死率44.93%.基础疾病以血液系统恶性疾病最多.69例中并发急性呼吸窘迫综合征17例,并发脓毒性休克34例.脓毒症伴1、2、3及3个以上器官功能衰竭病死率分别为11.76%、36.00%、64.29%和84.62%.单因素分析显示.国内小儿危重病例评分(PCIS)、最初PICU死亡危险因索评分(PRISM)、7d内最高PRISM、血小板计数、血清乳酸值、休克和多脏器功能不全综合征(MODS)受累脏器数7个变量与儿童严重脓毒症的死亡有关.经逐步引入剔除法,建立Logistic回归模型,仍然与死亡有关的因素包括血小板计数、血清乳酸值、休克和MODS受累脏器数.结论 儿童严重脓毒症病死率高,血小板计数F降、血清乳酸增高、脓毒性休克和MODS是疾病死亡的危险因素.

Risk factors associated with the death of childhood severe sepsis

Objectives To investigate risk factors associated with the death of pediatric severe sepsis, for early- recognizing and diagnosing, improving prognosis and decreasing mortality. Methods A nest case control study was em- ployed, and 69 patients in pediatric intensive care unit (PICU) diagnosed as severe sepsis were enrolled from Jan 2007 to June 2008. From the start of the hospitalization, 24 variables such as age, sex, underlying disease, infected site, etiolo- gy, clinical signs, complication and therapeut...
