Mini-dose Dexmedetomidine-Esketamine Supplemented Analgesia in Patients at High-risk of OSA
Mini-dose Dexmedetomidine-Esketamine Supplemented Analgesia for Postoperative Sleep Promotion in Patients at High-risk of Obstructive Sleep Apnea: A Randomized Trial
Peking University First Hospital
100 participants
Sep 11, 2024
INTERVENTIONAL
Conditions
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.

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.
