Postoperative delirium, a brain function impairment in elderly patients, complicates surgical recovery. Management involves medications and environmental changes to mitigate risks and improve patient outcomes.

Area of Science:

  • Neuroscience
  • Geriatric Medicine
  • Anesthesiology

Background:

  • Delirium is a global impairment of upper brain functions, often seen postoperatively, especially in the elderly.
  • High-risk surgeries include vascular, orthopedic, and long-duration procedures.
  • Postoperative delirium increases patient discomfort, management difficulty, costs, mortality, and morbidity, with unclear direct causality.

Purpose of the Study:

  • To review the current understanding and management strategies for postoperative delirium.
  • To highlight the impact of delirium on patient outcomes and healthcare costs.
  • To discuss pharmacological and non-pharmacological interventions for prevention and treatment.

Main Methods:

  • Literature review of studies on postoperative delirium.

  • Analysis of risk factors, clinical presentation, and consequences.
  • Evaluation of current and potential therapeutic interventions.

    • Main Results:

    • Elderly patients undergoing specific surgeries face higher delirium incidence.
    • Delirium is linked to adverse outcomes, including mortality and delayed recovery.
    • Pharmacological options include neuroleptics and benzodiazepines; non-pharmacological strategies like environmental modifications are also crucial.

    Conclusions:

    • A comprehensive approach combining pharmacotherapy and environmental interventions is essential for managing postoperative delirium.
    • Further research is needed on atypical neuroleptics and melatonin for delirium management.
    • Addressing delirium is critical for improving patient safety and recovery post-surgery.
