Objective To analyze many indicators during perioperative period of liver transplantation in patients with end-stage liver disease ,only to seek related factors that can accurately predict short-term(≤ three months)outcome .Methods We analyzed retrospectively clinical data of consecutive patients with end-stage liver diseases undergone liver transplantation in a single treatment center .Logistic regression analysis was used to analyze the perioperative indicators including recipient gender ,age ,body mass index ,preoperative serum albumin level ,serum sodium concentration ,urea nitrogen level and donor-recipient blood group ,et al .Correlated factors were analyzed by the method of multivariate logistic regression .Statistical processing package was SAS 9 .1 .3 soft .The difference was statistically significant with P< 0 .05 .Results 18/165 patients died within 3 months after transplantation(mortality rate :10 .9 ％ ) .According to the result of univariate analysis ,the indicators correlated with early mortality which were statistically significant were preoperative serum sodium , blood urea nitrogen ,PT-INR ,CTP score ,MELD score and MELD-Na score .On the base of the result of Logistic multiple regression . However ,only MELD-Na score was associated with 3 months prognosis(P=0 .001 ,β=-2 .510 ,OR=0 .088 ,95 ％ CI=0 .037～0 .349) .Conclusions Preoperative MELD-Na score is an independent risk factor for short-term survival in patients with end-stage liver disease .Higher MELD-Na score is ,the early mortality is higher .

Objective To evaluate the predictive effect of preoperative CTP score,MELD score and MELD-Na score on short-term prognosis (≤ 3 months) after liver transplantation,to analyze factors which correlated with survival,and to seek indicators that accurately predicted short-term outcomes.Methods The clinical data of 73 consecutive patients with end-stage liver diseases who underwent liver transplantation in a single center were retrospectively analyzed.The area under the ROC curve (AUC) was used to determine the predictive power.Correlated factors were analyzed by multivariate logistic regression.The statistical processing package used was SAS 9.1.3 software.Results 11 (15.1％) of 73 patients died within 3 months after liver transplantation.The areas under the ROC curve of the preoperative CTP score,MELD score and MELD-Na score for predicting short-term survival were 0.817,0.839 and 0.860 respectively.There was no significant difference among these 3 scoring systems.On univariate analysis,indicators significantly correlated with early mortality were preoperative serum sodium,serum urea,PT-INR,CTP score,MELD score and MELD-Na score.On logistic multiple regression,only MELD-Na score remained as a significant indicator (P =0.001,β =-2.496,OR =0.085,95％ CI:0.019 ～ 0.370).Conclusions The MELD-Na scoring system showed superior predictability of early mortality in patients who underwent liver transplantation.The preoperative MELD-Na score was an independent risk factor of short-term survival.The higher the MELD-Na score,the higher was the early mortality.
