Background: The administration of potassium solutions may result in hyperpotassemia during surgery; normal saline solution (NSS) traditionally used in renal transplant may cause hyperchloremic acidosis. Objective: To compare the safety of Lactated Ringer's (LR) against NSS in renal transplantation. Search strategy: A systematic review was completed on Central Cochrane Registry - controlled trials, Medline, Lilacs, EBSCO and Embase, accessing review articles and contacting expert clinicians. There was no language restriction. Selection criteria: Randomized controlled trials on adult patients undergoing renal transplantation. Data collection and analysis: Independent trial selection, quality assessment and data extraction were performed. The mean differentials were estimated with a 95% confidence interval (95% CI). Heterogeneity was evaluated with statistic I-square(I²) and the fixed and random effect models were used. Results: Four trials with a total of 237 patients were included. At the end of surgery, the potassium differential was non-significant (means difference (MD: -0.26 mEq/L; CI 95%: -0.58 to 0.05 p = 0.10; I² = 75%); the pH was lower in the NSS group (MD: 0.06; CI 95%: 0.05-0.08; p < 0.001; I² = 17%). No difference in Creatinine was identified on the third postoperative day (MD: -0.05; CI 95%: -0.59 to 0.48; p = 0.85; I² = 0%). Condusions: The use of RL vs. NSS during the renal transplantation perioperative period results in lower potassium and chloride levels and a higher pH, with no significant Creatinine changes.
