The influence of intraoperative central venous pressure on delayed graft function in renal transplantation: a single-center experience

Abstract

Introduction: Delayed graft function (DGF) is a common complication in kidney transplantation. We sought to evaluate possible correlates for DGF including intraoperative parameters, focusing on fluid replacement and central venous pressure (CVP) values among patients undergoing kidney transplantation at our center.

Methods: One hundred fifty-five cadaveric donor transplantations performed at our center between 2001 and 2005 were selected for the study. We compared intraoperative parameters together with 15 other clinical and socio-demographic recipient and donor variables among patients experiencing DGF (n = 58) versus those with immediate graft function (IGF; n = 97). All significant variables at P < .05 upon univariate analysis were entered into a multivariate logistic regression model to identify risk factors for DGF.

Results: CVP at awakening of ≤8 mm Hg (odds ratio [OR] = 3.53; 95% confidence interval [CI], 1.63-7.63), fluid input during surgery ≤2.250 mL (OR = 2.12; 95% CI, 1.00-4.51), and recipient age ≥50 years (OR = 2.72; 95% CI, 1.11-6.68) were the strongest correlates of DGF.

Conclusions: Our data suggested that reduced intraoperative perfusion as measured using CVP monitoring might increase DGF risk. This study provides the rationale to further investigate the optimal CVP target during this surgery.
