Area of Science:

  • Medical Science
  • Gerontology
  • Neuroscience

Background:

  • Delirium is a common and serious postoperative complication.
  • Its varied presentation can lead to underdiagnosis or misdiagnosis.
  • High patient morbidity and mortality are associated with delirium.

Observation:

  • Predisposing factors include advanced age, cerebral disease, and poor preoperative health.
  • Postoperative precipitants involve infection, hypoxia, ischemia, metabolic issues, and anticholinergic drugs.
  • Cholinergic pathways are implicated in delirium's pathogenesis, though not fully understood.

Findings:

  • Accurate identification using DSM-IV criteria is crucial for postoperative patients with mental status changes.
  • Investigations should target treatable organic precipitants.
  • Diagnostic workup requires a tailored, non-algorithmic approach.

Implications:

  • Delirium is potentially preventable through optimized patient medical status and avoidance of known precipitants.
  • Supportive care should involve a multidisciplinary approach to prevent functional decline.
  • Pharmacological intervention, such as haloperidol, may be necessary for agitation.
