BACKGROUND: This study aimed to quantify changes in acid-base balance, potassium and lactate levels as a function of administration of different crystalloid solutions during kidney transplantation, and to determine the ideal fluid for such patients.
METHODS: In this double-blind study, patients were randomized to three groups (n = 30 each) to receive either normal saline, lactated Ringer's, or Plasmalyte, all at 20-30 mL [middle dot] kg-1 [middle dot] h-1. Arterial blood analyses were performed before induction of anesthesia, and at 30-min intervals during surgery, and total IV fluids recorded. Urine volume, serum creatinine and BUN, and creatinine clearance were recorded on postoperative days 1, 2, 3, and 7.
RESULTS: There was a statistically significant decrease in pH (7.44 /- 0.50 vs 7.36 /- 0.05), base excess (0.4 /- 3.1 vs -4.3 /- 2.1), and a significant increase in serum chloride (104 /- 2 vs 125 /- 3 mM/L) in patients receiving saline during surgery. Lactate levels increased significantly in patients who received Ringer's lactate (0.48 /- 0.29 vs 1.95 /- 0.48). No significant changes in acid-base measures or lactate levels occurred in patients who received Plasmalyte. Potassium levels were not significantly changed in any group.
CONCLUSIONS: All three crystalloid solutions can be safely used during uncomplicated, short-duration renal transplants; however, the best metabolic profile is maintained in patients who receive Plasmalyte.
