Input: Six studies (477 participants) were included in the review. All participants were adult kidney transplant recipients and 70% of participants underwent live-donor kidney transplantation. The overall risk of bias was low for selection bias and unclear for remaining domains. There was no difference in the risk of delayed graft function (3 studies, 298 participants: RR 1.03, 95% CI 0.62 to 1.70) or hyperkalaemia (2 studies, 199 participants: RR 0.48, 95% CI 0.04 to 6.10) for participants who received balanced electrolyte solutions compared to normal saline. Intraoperative balanced electrolyte solutions compared to normal saline were associated with higher blood pH (3 studies, 193 participants: MD 0.07, 95% CI 0.05 to 0.09), higher serum bicarbonate (3 studies, 215 participants: MD 3.02 mEq/L, 95% CI 2.00 to 4.05) and lower serum chloride (3 studies, 215 participants: MD -9.93 mmol/L, 95% CI -19.96 to 0.11). There were four cases of graft loss in the normal saline group and one in the balanced electrolyte solution group, and four cases of acute rejection in the normal saline group compared to two cases in the balanced electrolyte solution group. Balanced electrolyte solutions are associated with less hyperchloraemic metabolic acidosis compared to normal saline, however it remains uncertain whether lower-chloride solutions lead to improved graft outcomes compared to normal saline.
Output:

We found six studies that included 477 kidney transplant patients. The majority of these patients had a kidney transplant from a living donor. The overall quality of the studies was low to average, and the main problem was the small number of studies and the small size of the studies. There was no information on funding source for most of the studies. Compared to normal saline, giving kidney transplant patients solutions that contain less chloride during their transplant operation resulted in lower blood acid levels but did not affect how the transplant kidney worked after surgery, or the number of patients who had high blood potassium levels. Harmful effects were not reported in many studies. In the group of patients who were given lower-chloride fluids, the transplant failed in one patient and one patient rejected the transplant. In the group of patients who were given normal saline, the transplant failed in four patients, and two patients rejected the transplant. However, this is probably an incomplete picture of harmful effects.
