Esketamine Combined With Remimazolam on Postoperative Sleep Disturbance and Anxiety in Patients

Effect of Esketamine Combined With Remimazolam on Postoperative Sleep Disturbance and Anxiety in Patients Undergoing Gastroenteroscopies

To explore the effects of esketamine combined with remimazolam on postoperative sleep disturbance and anxiety in surgical patients undergoing gastroenteroscopies

Postoperative sleep disturbance (PSD) occur in the form of sleep deprivation, circadian rhythm disturbance, and structural abnormalities, and have a high incidence in patients undergoing surgery. Postoperative sleep disorders can lead to postoperative delirium and cognitive dysfunction, aggravate postoperative acute pain, and delay postoperative recovery.

Benzodiazepines have a certain sedative hypnotic anti-anxiety effect, and remimazolam as a new benzodiazepine, its sedative hypnotic anti-anxiety effect is worthy of further exploration.Esketamine is an NMDA receptor antagonist with analgesic and sedative effects, and is widely used in clinical treatment of refractory depression. For patients undergoing surgery, in addition to sedation and analgesia, whether the intraoperative use of esketamine has positive effects on postoperative sleep disturbance and anxiety is worth exploring.
