Perioperative sleep management in cardiac surgery: an evidence-oriented narrative review of pharmacological, behavioral, and respiratory support strategies
To summarize pharmacological interventions, behavioral therapies, and respiratory support strategies for managing perioperative sleep disturbances in cardiac surgery.
Approach:
Pharmacological Interventions: Melatonin and receptor agonists may improve subjective sleep quality, but their effects on delirium and sleep architecture are inconsistent. Dexmedetomidine has sedative properties but poses hemodynamic risks. GABAergic hypnotics may reduce sleep latency but increase the risk of respiratory depression and cognitive impairment.
Key Findings:
Perioperative sleep disturbance is common in cardiac surgery and linked to postoperative delirium and cognitive decline.
Pharmacological agents show inconsistent results in improving sleep quality and outcomes.
Behavioral and environmental strategies are feasible but require further validation in cardiac surgical contexts.
Respiratory support primarily aids oxygenation without clear evidence of enhancing sleep quality.
Interpretation:
Risk-stratified multimodal sleep management is clinically rational, but further large-scale studies are needed to clarify efficacy and safety.
Limitations:
Evidence primarily derived from non-cardiac surgical or ICU populations may not fully apply to cardiac surgical patients.
Inconsistencies in study findings regarding pharmacological interventions limit definitive conclusions.
Conclusion:
A systematic integration of multiple intervention strategies is essential for managing perioperative sleep disturbances in cardiac surgical patients.
