Abstract

BACKGROUND Serum sodium (Na) is considered to reflect the severity of liver cirrhosis. In the last few years, much effort has been made to integrate this association into prognostic models after liver transplantation. The aim of this study was to investigate the associations between peritransplant Na and neurological complications, as well as short-term survival, after liver transplantation. MATERIAL AND METHODS A total of 306 liver transplantations between 2012 and 2015 were evaluated. Pre- and posttransplant sodium concentrations were investigated with regard to 3-month survival and incidence of posttransplant neurological complications, along with other factors present in the operative side of the recipient and donor. RESULTS The 3-month survival rate was 94%. Neither hyponatremia (/L) nor hypernatremia (>145 mEq/L) at pretransplantion predicted 3-month survival. A large amount of intraoperative blood transfusion and a large delta Na showed a significant association with poor outcomes at 3 months. On multivariate analysis, the requirement of blood transfusion and warm ischemia time remained independent prognostic factors for 3-month mortality. Hyponatremia and a large delta Na tended to lead to the frequent development of neurological complications. These complications, secondary to rapid Na correction, were concerning and potentially led to a prolonged hospital stay and early mortality. CONCLUSIONS Rapid change in the sodium level might be caused by large amounts of blood transfusion products. This leads to a diminished short-term survival, as well as a higher rate of neurological complications.
