Brief Summary

The investigators sought to compare the effect of two preload targets of stroke volume variation of ≤6% and ≤12% on the postoperative renal function in patients undergoing living donor kidney transplantation. Goal-directed fluid therapy will be performed in both groups to maintain adequate stroke volume, stroke volume variation, mean arterial pressure (or systemic vascular resistance) during kidney transplantation. Only the preload target for giving crystalloid during surgery will be different between groups.

Detailed Description

The adequate preload target of fluid management has not yet been established during kidney transplantation. Traditionally, sufficient intravascular volume status has been recommended to maintain perfusion to renal graft. Stroke volume variation was reported to be superior to the traditional target of central venous pressure. In this regard, the investigators sought to compare the effect of two preload targets of stroke volume variation of ≤6% and ≤12% on the postoperative renal function in patients undergoing living donor kidney transplantation. Goal-directed fluid therapy will be performed in both groups to maintain adequate stroke volume, stroke volume variation, mean arterial pressure (or systemic vascular resistance) during kidney transplantation. Only the preload target for giving crystalloid during surgery will be different between groups.

target of Stroke Volume Variation ≤ 6%Crystalloid fluid administration with the target of stroke volume variation ≤ 6%The rate of intraoperative fluid administration will be adjusted to achieve the target of Stroke Volume Variation ≤ 6%. A crystalloid bolus of 200 ml will be repeatedly administered every 20 min until the target was achieved. The basal rate of fluid administration will be 3 ml/kg/hr.

A crystalloid bolus of 200 ml will be repeatedly administered every 20 min until the target was achieved. The basal rate of fluid administration will be 3 ml/kg/hr.
