The Effect of Esketamine on Sleep Disturbance

The Effect of a Single Low Dose of Esketamine During Surgical Abortion in Patients With Sleep Disturbance

To explore the efficacy of a single low dose of esketamine during surgical abortion in patients with sleep disturbance

Sleep disturbance occur in the form of sleep deprivation, circadian rhythm disturbance, and structural abnormalities. Women who requires surgical abortion due to fetal anomaly or unwanted pregnancy often experience sleep disturbance. Severe sleep disturbance is a strong indicator for postoperative sleep disorders, which can lead to postoperative delirium and cognitive dysfunction, aggravate postoperative pain, and delay postoperative recovery.

Esketamine is an N-methyl-D-aspartate(NMDA) receptor antagonist with analgesic and sedative effects, and is widely used in clinical treatment of refractory depression. For patients undergoing surgical abortion, in addition to sedation and analgesia, whether the intraoperative use of esketamine has positive effects on sleep disturbance is worth exploring.
