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

China120 participantsStarted 2025-09-01

Plain-language summary

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.

Exclusion Criteria: * Patients who do not sign the informed consent; * patients with severe diseases of major organs such as the heart, brain, lungs, liver, and kidneys; * patients with adverse drug reactions to esketamine or magnesium sulfate; * patients with uncontrolled hypertension or hyperthyroidism; * patients with endocrine and metabolic diseases or neurological diseases; * pregnant or lactating women; * long-term users of sedatives, analgesics, or long-term alcohol abusers; * patients with a history of mental illness, language communication barriers, or inability to understand the content of the experiment; * patients with difficult airways during anesthesia induction requiring a change in the conventional intubation method; * patients with sinus bradycardia or atrioventricular block; * patients with concurrent cholangitis, biliary obstruction, or pancreatitis.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
