Postoperative neurocognitive dysfunction (PND) is a prevalent and debilitating complication in elderly surgical patients, characterized by persistent cognitive decline that negatively affects recovery and quality of life. As the aging population grows, the rising number of elderly surgical patients has made PND an urgent clinical challenge. Despite increasing research efforts, the pathophysiological mechanisms underlying PND remain inadequately characterized, underscoring the need for a more integrated framework to guide targeted interventions.

Perioperative neurocognitive disorders (PND) is a common complication affecting the central nervous system, commonly induced by anesthesia and surgical procedures. PND has garnered considerable attention in recent years, not only due to its high morbidity but also its negative impact on patient prognosis, such as increased rates of dementia and mortality. Sevoflurane, a common volatile anesthetic in clinical practice, is increasingly linked to being a potential risk factor for PND with prolonged inhalation, yet effective prevention and treatment methods remain elusive.

Animal models investigating sevoflurane or compound A and renal function serve as the initial basis for concerns regarding renal injury following sevoflurane anesthesia and subsequent recommendations of minimum fresh gas flow, but this evidence basis has not been critically appraised. Primary literature searches were performed in MEDLINE OVID, PubMed, EMBASE, the Cochrane Library), the Cochrane Central Register of Controlled Trials, the International HTA Database, CINAHL, and Web of Science to identify randomized controlled trials and quasi-experimental studies in animals utilizing sevoflurane or compound A. The primary outcomes included renal function as determined by blood urea nitrogen, serum creatinine, creatinine clearance, and urine volume.

Sevoflurane (Sev) is a widely applied anesthetic in clinical practice; however, it could induce neurotoxicity and lead to postoperative cognitive dysfunction (POCD). This study aimed to investigate the role and underlying mechanism of circHOMER1 in Sev-induced neurotoxicity and POCD. Sev treated mouse hippocampal neuronal HT22 cells and SD rats.
