ABSTRACT

Background: Intraoperative fluid therapy is essential in maintaining adequate tissue perfusion, oxygenation, and preventing hypovolemia and hypotension. Various factors contribute to intraoperative hypotension, which can lead to organ damage. Maintaining optimal plasma volume is crucial for adequate cardiac output, but excessive interstitial fluid volume can hinder tissue oxygen delivery. Cardiac surgery presents unique challenges in fluid therapy management, and postoperative patients may experience relative blood volume insufficiency and interstitial edema. Method: This study compared the effects of balanced salt solution and Ringer Lactate fluid administration during cardiac surgeries on cardiopulmonary bypass. The study assessed their impact on plasma electrolytes, acid-base status, and renal function in these patients. Result: Balanced salt solution and Ringer Lactate fluid administration had similar effects on plasma electrolytes, acid-base status, and renal function in patients undergoing cardiac surgeries on cardiopulmonary bypass. Conclusion: Although both balanced salt solution and Ringer Lactate fluid administration had similar effects on plasma electrolytes, acid-base status, and renal function, balanced salt solution may be preferred due to its closer resemblance to plasma composition and avoidance of hyperchloremic acidosis.
