Effect of Esketamine on Depressive Symptoms of Obese Patients Undergoing Laparoscopic Sleeve Gastrectomy

Abstract

Esketamine, as a powerful analgesic intravenous anesthetic, has a rapid onset and elimination effect, does not inhibit spontaneous respiration, and can slightly stimulate the circulatory system. It has been confirmed that esketamine can effectively combat opioid related complications, especially life-threatening respiratory suppression. Thus becoming a new powerful perioperative analgesic drug. At the same time, esketamine has been licensed for the treatment of "resistant depression" and emergency treatment for patients in crisis states of depression. But the evidence for its safety and effectiveness is insufficient. We have designed a randomized controlled clinical trial to investigate the effect of an established general anesthesia strategy without opioids by using esketamine on postoperative depressive in obese patients undergoing laparoscopic sleeve gastrectomy.
