In Brief
A Phase 4 clinical trial evaluating Dexmedetomidine-esketamine combination and Placebo for Obstructive Sleep Apnea and 4 related conditions. Currently recruiting, targeting 100 participants across 1 site.

Detailed Summary
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.

Timeline
Interventions
Patient-controlled analgesia is established with dexmedetomidine (1 μg/ml), esketamine (1 mg/ml), and sufentanil (1 μg/ml) in a total volume of 100 ml. The pump is programmed to deliver 2-ml boluses at 6 to 8-minute lockout intervals with a background infusion rate at 1 ml/h. Patient-controlled analgesia is provided for at least 24 hours but no more than 48 hours after surgery.
