不同液体管理策略对感染性休克患者病死率的影响

目的 探讨感染性休克不同时期采用不同液体管理策略对患者病死率的影响.方法 回顾性分析2007年3月至2009年12月江苏省苏北人民医院重症监护病房(ICU)107例感染性休克患者的临床资料,按28 d预后分为存活组(68例)和死亡组(39例);比较两组急性生理学与慢性健康状况评分系统Ⅱ(APACHE Ⅱ)评分、感染相关器官功能衰竭评分系统(SOFA)评分、1周内每日液体出入量及平衡、24 h早期目标导向治疗(EGDT)和24 h后保守性液体管理(CLFM)等数据,对影响患者预后的因素进行Logistic回归分析,确定和描述感染性休克患者的预后与24 h EGDT和24 h后CLFM策略间的关系.结果 单因素相关分析显示,两组7 d氧合指数、24 h乳酸清除率、急性肺损伤发生、机械通气时间、ICU住院时间、总住院时间、液体管理指标比较差异均有统计学意义.多元回归分析显示,未达到24 h EGDT、24 h后未达到CLFM、1周液体负平衡＜2000 ml和1周液体总入量＞20000 ml是感染性休克患者死亡的独立危险因素,其优势比(OR)分别为4.159、4.431、23.788、4.353,P值分别为0.035、0.019、0.000、0.025.达到24 h EGDT且24 h后实行CLFM策略的感染性休克患者28 d病死率(12.5%)明显低于达到24 h EGDT且24 h后实行开放性液体管理(LLFM)策略者(46.2%),以及未达到24 h EGDT且24 h后实行CLFM策略或LLFM策略者(30.0%、76.2%,P＜0.05或P＜0.01).结论 感染性休克早期达到24 h EGDT且24 h后采取CLFM策略可降低患者的病死率.

Abstract：

Objective To find out the influential effect of different fluid management on mortality of patients with septic shock in different phases. Methods From March 2007 to December 2009, a retrospective controlled study was conducted on the clinical data of 107 adult patients with septic shock in the intensive care unit(ICU)of Subei Hospital of Jiangsu Province. The patients were divided into survival group(n=68)and non-survival group(n= 39)according to the final outcome. A number of demographic and variables were collected from the medical record. The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ)score, sequential organ failure assessment(SOFA), liquid intake and output volume and its balance daily within 1 week, 24-hour early goal-directed therapy(EGDT)and conservative late fluid management(CLFM)were compared between two groups. The Logistic regression statistics was used to determine the relationship between APACHE Ⅱ , SOFA, EGDT, CLFM and survival. Results The single variable analysis showed that there was significant difference in the parameters of oxygenation index in 7 days, arterial blood lactate clearance within 24 hours, acute lung injury, length of mechanical ventilation,length of ICU stay and in hospital, the goal of fluid management including 24-hour EGDT, 24-hour CLFM,fluid balance in 24 hours, total fluid input within 7 days, negative fluid balance and times during 7 days between two groups. Logistic regression showed that failure to achieve 24-hour EGDT and late CLFM, a negative balance of ＜2 000 ml, total fluid input of ＞20000 ml within 1 week were independent risk factors of death, and odds ratio(OR)was 4. 159, 4. 431, 23. 788 and 4. 353, respectively, the P value was 0. 035,0. 019, 0. 000, 0. 025, respectively. The 28-day mortality in 24-hour EGDT and CLFM group(12. 5 %)was significantly lower than that of 24-hour EGDT with liberal late fluid management(LLFM)group(46. 2%)and that in the group of patients in whom with failure to have 24-hour EGDT with CLFM or LLFM(30.0%,76.2%, P＜0. 05 or P＜0. 01). Conclusion Both early achievement of 24-hour EGDT and late CLFM for the patients with septic shock can lower mortality.
