Purpose: Living kidney transplantation is a common treatment for end-stage renal disease. The impact of anaesthetics on postoperative biomarkers of renal injury in living kidney transplant donors is not well understood.
Patients and Methods: 70 transplant donors who underwent kidney extraction were randomly assigned to following two groups: sevoflurane (S group) and propofol (P group). Urine and blood were collected before induction and 1, 2, 6 days after operation. Kidney injury marker-1 (KIM-1), interleukin-18 (IL-18) and tissue inhibitor of metalloproteinase-2 (TIMP-2) were measured by enzyme-linked immunosorbent assay. Record the cystatin C, glomerular filtration rate, urine output during perioperative period.
Results: There were both increases in biomarkers of kidney injury before and 1, 2 and 6 days after the anaesthetic surgery in donors, However, no statistical differences in KIM-1 (P (0.42 pg/mL (95% CI 0.21 to 0.63 pg/mL)) vs S (0.26 pg/mL (95% CI 0.02 to 0.49 pg/mL)), − 0.16 pg/mL (95% CI − 0.48 to 0.16 pg/mL)), IL-18 (P (178.54 pg/mL (95% CI 110.15 to 24693 pg/mL)) vs S (175.86 pg/mL (95% CI 100.35 to 251.38 pg/mL)), − 2.68 pg/mL (95% CI − 105.61 to 100.25 pg/mL)), and TIMP-2 (P (12.88 ng/mL (95% CI 8.69 to 17.07 ng/mL)) vs S (14.85 ng/mL (95% CI 10.23 to 19.46 ng/mL)), 1.97 ng/mL (95% CI − 4.30 to 8.23 ng/mL)) concentration changes between the two types of anaesthesia.
Conclusion: There was no difference between sevoflurane and propofol anaesthesia on postoperative changes in biomarkers of renal injury in living kidney transplant donors.
