Comparison of the Effects of General Anesthesia and Combined Spinal-Epidural Anesthesia on Ferroptosis, Humanin and MOTS-c Levels in Renal Transplantation

Summary

Renal transplantation is the most effective renal replacement therapy for patients with end-stage renal disease. Ischemia-reperfusion injury may adversely affect graft function and long-term outcomes. Ferroptosis has recently emerged as a potential mechanism involved in ischemia-reperfusion injury, while the mitochondrial-derived peptides humanin and MOTS-c are thought to exert protective effects against oxidative stress. However, the effects of different anesthetic techniques on these biomarkers in kidney transplant recipients have not been investigated. This prospective controlled study aims to compare the effects of sevoflurane general anesthesia (SGA) and combined spinal-epidural anesthesia (CSEA) on serum ferroptosis markers, humanin, and MOTS-c levels in adult kidney transplant recipients. Blood samples will be obtained perioperatively for biomarker analysis. The primary objective of the study is to evaluate the effects of the anesthetic technique on serum ferroptosis markers, humanin, and MOTS-c levels. Secondary objectives include evaluating early graft function and postoperative outcomes by assessing the incidence of delayed graft function, postoperative serum creatinine levels, requirement for dialysis, urine output, length of hospital stay, and the association of these outcomes with perioperative biomarker levels.
