Fluid management being an important component of surgery becomes more challenging for an anesthesiologist in case of renal transplant. Ischemia-reperfusion injury is an inevitable consequence of kidney transplantation, leading to metabolic acidosis .Normal saline (NS; 0.9% NaCl) is administered during kidney transplantation to avoid the risk of hyperkalemia associated with potassium-containing fluids. Plasmalyte is another fluid which can be used and probably will lead to better metabolic profile in these group of patients.The primary objective of this study will be to compare the effects of using normal saline (NS), Ringer lactate and Plasmalyte as intravenous fluids on acid-base balance and electrolytes during living donor kidney transplantation. Secondary outcomes assessed will be the effect on renal function.
