Postoperative acute kidney injury (PO-AKI) is a significant complication, especially after complex surgeries. The choice of anesthetic may influence PO-AKI risk. While sevoflurane (SEVO) has been associated with potential renal risks, dexmedetomidine (DXM) has demonstrated renoprotective effects in various surgical settings. These protective effects may be linked to DXM's immunomodulatory properties and influence on the redox balance. Given the common use of SEVO in major non-cardiac surgery and the potential for renal vulnerability, particularly in the elderly, this study hypothesizes that perioperative DXM infusion in patients undergoing major non-cardiac surgery with SEVO anesthesia will reduce the incidence and severity of PO-AKI, especially in those with pre-existing or borderline renal dysfunction.
