Esketamine Combined With Magnesium Sulfate for Postoperative Fatigue Syndrome in Patients Undergoing Laparoscopic Cholecystectomy

Laparoscopic cholecystectomy (LC), while minimally invasive, triggers postoperative fatigue syndrome (POFS) through mechanisms including ischemia-reperfusion injury, neuroendocrine stress (sustained cortisol elevation), and inflammation-driven mitochondrial dysfunction (IDO-mediated kynurenine production). Esketamine, an NMDA receptor antagonist, counteracts POFS by blocking central sensitization, suppressing neuroinflammation (e.g., microglial IL-6 release), and enhancing neuroplasticity via BDNF/TrkB upregulation. Magnesium sulfate complements this by antagonizing NMDA/voltage-gated calcium channels to reduce inflammation and calcium overload, while optimizing cellular energy metabolism as an ATPase cofactor and alleviating muscle spasms. Crucially, their combination holds synergistic potential: esketamine targets central fatigue pathways, while magnesium addresses peripheral metabolic and muscular components. This study aims to determine their individual and interactive effects on POFS, recovery quality, and sleep outcomes in LC patients, establishing an efficient, safe strategy to accelerate postoperative rehabilitation.
