We attempt to evaluate the prognostic potential of NT-proBNP in combination with the sequential organ failure assessment （SOFA） score in sepsis. Methods In this retrospective study, 100 consecutive sepsis patients were enrolled. Clinical data such as admission SOFA, the Acute Physiologic and Chronic Health Evaluation score, shock prevalence, use of lung protective ventilation, vasopressors, and glucocorticoids were recorded. Additionally, serum creatinine （Scrl and Scr3） and NT-proBNP （NT-proBNP1 and NT-proBNP3） were assayed and evaluated at admission and on day 3 respectively. Results ANT-proBNP （NT-proBNP3 minus NT-proBNP1） （P 〈0.001, Hazard ratio （HR）=1.245, 95% confidence interval （CI）, 1.137-1.362） and admission SOFA （P 〈0.001, HR=1.197, 95% CI, 1.106-1.295） were independently related to in-hospital mortality. Their combination was a more robust predictor for in-hospital mortality than either of them individually. Patients with high ANT-proBNP and SOFA had the poorest prognosis. Conclusions In our study, both ANT-proBNP and SOFA were independent predictors of septic patients＇ prognosis. Moreover, the combination of ,~NT-proBNP and admission SOFA provided a novel strategy that contained information regarding both the response to treatment and sepsis severity.展开更多

This study aimed to assess the associated risk factors of AKI in the critically ill patients undergoing AAA repair and to evaluate the appropriate AKI management in the specific population. Methods We retrospectively examined data from all critically ill patients undergoing AAA repairs at our institution from April 2007 to March 2012. Multivariable analysis was used to identify factors associated with postoperative AKI, which was defined by risk, injury, failure, loss and end-stage （RIFLE） kidney disease criteria. The goal-directed hemodynamic optimization （maintenance of optimal hemodynamics and neutral or negative fluid balance） and renal outcomes were also reviewed. Results Of the 71 patients enrolled, 32 （45.1%） developed AKI, with 30 （93.8%） cases diagnosed on admission to surgical intensive care unit （SICU）. Risk factors for AKI were ruptured AAA （odds ratio （OR）=5.846, 95% confidence interval （CI）： 1.346-25.390）, intraoperative hypotension （OR=6.008, 95% CI： 1.176 to 30.683）, and perioperative blood transfusion （OR=4.611, 95% CI： 1.307-16.276）. Goal-directed hemodynamic optimization resulted in 75.0% complete and 18.8% partial renal recovery. Overall in-hospital mortality was 2.8%. AKI was associated with significantly increased length of stay （（136.9±24.5） hours vs. （70.4±11.3） hours） in Surgical Intensive Care Unit. Conclusions Critically ill patients undergoing AAA repair have a high incidence of AKI, which can be early recognized by RIFLE criteria. Rupture, hypotension, and blood transfusion are the significant associated risk factors. Application of goal-directed hemodynamic optimization in this cohort appeared to be effective in improving renal outcome.展开更多
