Efficacy of subanaesthetic esketamine on the prevention of postoperative delirium in older adult patients after cardiovascular surgery: protocol for a single-centre, randomised, double-blind, placebo-controlled trial (SEPDOC trial) in China Open
Introduction Postoperative delirium (POD) is a common and serious complication in older adult patients undergoing cardiovascular surgery. Esketamine is known for its anti-inflammatory and neuroprotective properties. While it has shown prev…
