CT分类标准在评估重症急性胰腺炎预后中的价值

目的 探讨CT分类标准在评估重症急性胰腺炎(SAP)预后中的价值.方法 回顾性分析2000年1月至2009年12月收治的62例SAP患者的一般资料,所有患者发病早期均行非手术治疗,并于入院后72 h内行CT检查.依照Balthazar CT分级,所有病例被分成3级:C级13例、D级26例、E级23例.依照Balthazar CT严重度指数(CTSI)评分,将此结果分为3级:Ⅰ级11例、Ⅱ级39例、Ⅲ级12例.分析Balthazar CT分级及CTSI评分与患者住院天数、发热天数、禁食天数、白细胞计数恢复天数、血淀粉酶恢复天数、胰腺假性囊肿形成、器官功能衰竭、中转手术、死亡的相关性.用所有患者的两种CT分级评分绘制受试者工作特征曲线(ROC),通过计算曲线下面积来比较各评分系统在判断SAP病情严重程度和预后的意义.结果 不同Balthazar CT分级间白细胞计数恢复天数(F=4.035,P=0.023)及胰腺假性囊肿形成(x2=8.066,P=0.018)之间的差异有统计学意义,而其他判断SAP严重程度的临床病理学指标间差异无统计学意义(P＞0.05).CTSI评分低分值的SAP患者恢复过程较高分值者顺利,Ⅰ级及Ⅱ级患者的器官功能衰竭、中转手术、胰腺假性囊肿形成及病死率均明显低于Ⅲ级患者,差异有统计学意义(P＜0.01).ROC曲线分析显示CTSI评分较Balthazar CT分级能更准确地预测SAP的器官功能衰竭、胰腺假性囊肿形成、中转手术及死亡的发生.结论 CTSI评分对于评估SAP的预后有重要意义.

Combining sequential organ failure assessment (SOFA) score with acute physiology and chronic health evaluation (APACHE) II score to predict hospital mortality of critically ill patients

The ability to accurately adjust for the severity of illness in outcome studies of critically ill patients is essential. Previous studies have showed that Sequential Organ Failure Assessment (SOFA) score and Acute Physiology and Chronic Health Evaluation (APACHE) II score can predict hospital mortality of critically ill patients. The effects of combining these two scores to predict hospital mortality of critically ill patients has not been evaluated. This cohort study evaluated the performance of combining the APACHE II score with SOFA score in predicting hospital mortality of critically ill patients. A total of 1311 consecutive adult patients admitted to a tertiary 22-bed multidisciplinary intensive care unit (ICU) in Western Australia were considered. The APACHE II, Admission SOFA, Delta SOFA and maximum SOFA score were all related to hospital survival in the univariate analyses. Combining Max SOFA (area under receiver operating characteristic curve 0.875 vs. 0.858, P = 0.014; Nagelkerke R2: 0.411 vs. 0.371; Brier Score: 0.086 vs. 0.090) or Delta SOFA score (area under receiver operating characteristic curve 0.874 vs. 0.858, P = 0.003; Nagelkerke R2: 0.412 vs. 0.371; Brier Score: 0.086 vs. 0.090) with the APACHE II score improved the discrimination and overall performance of the predictions when compared with using the APACHE II score alone, especially in the emergency ICU admissions. Combining Max SOFA or Delta SOFA score with the APACHE II score may improve the accuracy of risk adjustment in outcome studies of critically ill patients.

A modified gastrointestinal failure score for patients with severe acute pancreatitis

Purpose

No consensus has been reached to define gastrointestinal failure (GIF) associated with severe acute pancreatitis (SAP). Reintam and colleagues proposed a scoring system of GIF for critically ill patients, but its suitability for patients with SAP is questionable. The present study evaluates a modified GIF score we developed to assess the GIF of patients with SAP.

Methods

The subjects of this study were 52 patients with SAP treated between September 2010 and July 2011. We recorded the Reintam’s GIF score, our modified GIF score, the acute physiology and chronic health evaluation (APACHE) II score, the sequential organ failure assessment (SOFA) score, and other clinical values during the first 3 days after admission. The prognostic value of the modified GIF score, for evaluating the severity and outcomes of SAP, was also assessed.

Results

Compared with the Reintam’s GIF score, the modified GIF score seemed to be more valuable for predicting hospital mortality (the area under curve, AUC 0.915 vs. 0.850), multiple organ dysfunction syndrome (MODS) (AUC 0.829 vs. 0.766), and pancreatic infection (AUC 0.796 vs. 0.776). Moreover, combining the modified GIF score and the SOFA or APACHEII scores resulted in more accurate prediction of the prognosis of SAP than either score alone.

Conclusion

The modified GIF score is useful for assessing gastrointestinal system function, which may serve as an early prognostic tool to evaluate the severity and predict the outcomes of SAP.

Der SOFA-Score in der Beurteilung septischer Krankheitsbilder Beziehungen zu MOD- und APACHE-II-Score

The SOFA score, a new system for patients with sepsis-related diseases, was introduced in 1994 by the "Working Group on Sepsis-Related Problems of the European Society of Intensive Care Medicine." The purpose of this study was to compare the new SOFA score with the APACHE II and MOD scores. The data on 874 patients from a surgical intensive care unit in an university hospital were analyzed using commercially available software (SPSS for Windows, Version 7.5.2 and MS Excel '97). To compare the different scores, receiver-operating characteristics (ROC)--analyses were applied. The study demonstrated clear correlation between an elevated SOFA score and the mortality of the patients during their ICU stay (score 0-->mortality 0%, 1-->3.6%, 2-->22.5%, 3-->86.7%, respectively r = 0.445; P = 0.01). The ROC analyses of the APACHE II, the MOD and the SOFA scores were comparable (area under the curve: APACHE II 0.73, MOD 0.77, SOFA 0.71). In conclusion, the SOFA score is reliable and might be useful in the daily routine of an intensive care unit.     

Comparison of the sequential organ failure assessment score with the King's College Hospital criteria and the model for end-stage liver disease score for the prognosis of acetaminophen-induced acute liver failure

Acetaminophen-induced acute liver failure (ALF) is a complex multiorgan illness. An assessment of the prognosis is essential for the accurate identification of patients for whom survival without liver transplantation (LT) is unlikely. The aims of this study were the comparison of prognostic models [King's College Hospital (KCH), Model for End-Stage Liver Disease, Sequential Organ Failure Assessment (SOFA), and Acute Physiology and Chronic Health Evaluation II (APACHE II)] and the identification of independent prognostic indicators of outcome. We evaluated consecutive patients with severe acetaminophen-induced ALF who were admitted to the intensive care unit. At admission, demographic, clinical, and laboratory parameters were recorded. The discriminative ability of each prognostic score at the baseline was evaluated with the area under the receiver operating characteristic curve (AUC). In addition, using a multiple logistic regression, we assessed independent factors associated with outcome. In all, 125 consecutive patients with acetaminophen-induced ALF were evaluated: 67 patients (54%) survived with conservative medical management (group 1), and 58 patients (46%) either died without LT (28%) or underwent LT (18%; group 2). Group 1 patients had significantly lower median APACHE II (10 versus 14) and SOFA scores (9 versus 12) than group 2 patients (P < 0.001). The independent indicators associated with death or LT were a longer prothrombin time (P = 0.007), the inspiratory oxygen concentration (P = 0.005), and the lactate level at 12 hours (P < 0.001). The KCH criteria had the highest specificity (83%) but the lowest sensitivity (47%), and the SOFA score had the best discriminative ability (AUC = 0.79). In conclusion, for patients with acetaminophen-induced ALF, the SOFA score performed better than the other prognostic scores, and this reflected the presence of multiorgan dysfunction. A further evaluation of SOFA with the KCH criteria is warranted.

Abstract Objective To evaluate the CT features and its’ clinical impact of abdominal compartment syndrome(ACS) complicated by severe acute pancreatitis(SAP). Methods A retrospective study was carried out on 23 cases of patients with ACS complicated by SAP admitted in our center from January 2008 to May 2011, to evaluate the CT features of ACS and its’ effect of assessing patients’ severity. Results The morbidity of ACS complicated by SAP in our center was 3.04%. In the 23 cases of patients, 12 cases was cured and 9 cases of them was cured by operation. The CTSI scores and the incidence of narrowing of inferior vena cava, elevation of the diaphragm, round belly sign was significant variable between the ACS and non-ACS patients. And the self-comparison of ACS patients showed that the incidence of narrowing of inferior vena cava, bowel wall thickening with contrast enhancement, elevation of the diaphragm was also significant variable. Among the seven CT features of ACS in previous articles, the frequency of those features had a significant variable in APACHEII??SOFA??MV days??CRRT days and mortality. Conclusions The CTSI scores and the incidence of narrowing of inferior vena cava, elevation of the diaphragm, round belly sign was significant variable between the ACS and non-ACS patients, and the frequency of CT features in previous articles also had a effect of assessing the ACS patients’ severity.
