POSTOPERATIVE SERUM CREATININ LEVEL IN TWO DIFERENT HYDRATION REGIMES IN LIVING DONOR KYDNEY TRANSPLANATATION

Abstract

Introduction: Early graft function is very important and can be achieved with adequate intraopeartive perfusion characteristics of the graft and urine output. The goal of this study was to examine the influence of targeting central venous pressure (CVP) on early graft function. Material and methods: After approval of Ethical committee of the Medical Faculty-Skopje, we obtained inform consent of 60 patients, ASA 2-3 undergoing renal transplantation of livingrelated person in the Clinic of Urology – Skopje. A prospective clinical study was performed in the period of 2 years. Patients were divided into 2 groups of thirty patients : group A receiving normal saline intraoperatively targeting for CVP to 15 mmHg until vascular clamps were off and group B receiving normal saline 10ml/kg/h. We recorded lactate at the end of the surgery, onset of diuresis and total urine output from unclamping the renal vessels to the end of the surgery in both groups and postoperative serum creatinine in 3times (3, 12, 36 hours). Results: The onset of diuresis in seconds was insignificantly longer in group B p>0,05 (p=o,31). The average value of postoperative levels of the lactate showed that in group B the levels of the lactate were significantly higher for Z=-5,79 and p<0,001 (p=0,000). We didn’t find any statistical differences in postoperative serum creatinine in both groups. Conclusion: Our study didn’t show any benefit from targeting CVP to 15 mmHg. We couldn’t find any significant difference on onset of diuresis and urine output after the unclamping the vessels. However, in the constant infusion group (group B) the level of the lactate was higher CVP. In postoperative biochemical parameters we had no statistical difference between the average values of serum cratinine.
