    Perioperative sleep disturbance is common in cardiac surgery, affecting sleep quality and continuity, and is linked to postoperative complications.

  • 2

    Melatonin and receptor agonists may improve subjective sleep quality, but their impact on delirium and hospital stay is inconsistent.

  • 3

    Dexmedetomidine has sedative effects similar to non-REM sleep, but its use is complicated by inconsistent findings and potential hemodynamic risks.

  • 4

    Behavioral interventions and environmental optimization are feasible but require cautious extrapolation from other patient populations.

  • 5

    Multimodal sleep management strategies are rational, yet large-scale studies are needed to clarify their efficacy and safety in cardiac surgical patients.
