About this study

Patients with obstructive sleep apnea (OSA) are at increased risk of developing sleep disturbances after surgery. Dexmedetomidine is a highly selective α2-adrenergic agonist with sedative, analgesic, and anxiolytic effects. Ketamine is a noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist. Esketamine is the S-enantiomer of racemic ketamine and twice as potent as racemic ketamine for analgesia. A recent trial showed that mini-dose esketamine-dexmedetomidine in combination with opioids improved analgesia and subjective sleep quality after scoliosis correction surgery. This trial is designed to test the hypothesis that mini-dose dexmedetomidine-esketamine supplemented analgesia may improve postoperative sleep quality in patients at high-risk of OSA.
