Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Subjective sleep quality during the first night after surgery.

    Subjective sleep quality is assessed with the Richards-Campbell Sleep Questionnaire (RCSQ). The RCSQ is a self-reported measure of subjective sleep quality with 5 items, including sleep depth, sleep latency, awakening, return to sleep, and overall sleep quality; the score of each item ranges from 0 to 100, with a higher score indicating better sleep.

    During the first night after surgery.

Secondary Outcomes (5)

  • Sleep structure parameters during the first night after surgery.

    During the first night after surgery

  • Cumulative subjective sleep quality score after surgery

    During the first three nights after surgery.

  • Proportion of patients with poor sleep quality after surgery.

    During the first three nights after surgery.

  • Area under curve of pain intensity score within 3 days after surgery.

    Up to 3 days after surgery.

  • Subjective sleep quality at 30 days after surgery.

    At 30 days after surgery.

Other Outcomes (5)

  • Sedation level within 3 days after surgery.

    Up to 3 days after surgery.

  • Length of stay in hospital after surgery.

    Up to 30 days after surgery.

  • Incidence of delayed neurocognitive recovery.

    At 30 days after surgery.

  • +2 more other outcomes

Study Arms (2)

Dexmedetomidine-esketamine combination

EXPERIMENTAL

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.

Drug: Dexmedetomidine-esketamine combination

Patient-controlled analgesia is provided for at least 24 hours but no more than 48 hours after surgery.

Drug: Placebo
