ICU sedation

Background

  • Sedation is commonly used for ICU patients
  • Agent choice determined by side effect profile and disease process

Uses

  • Can control agitation
  • Improves patient-ventilator synchrony
  • Decreases O2 consumption
  • Decrease intracranial pressure in neurosurgical patients

Agents

Adverse Effects

  • Drug and dose dependent, but generally include:
    • Hypotension
    • Respiratory depression
    • Withdrawal
    • Delirium
    • Arrhythmias

Monitoring

  • Several sedation monitoring scales are validated
  • Richmond Agitation and Sedation Scale most commonly used (RASS)
    • Lighter sedation associated with shorter ICU stay, decreased time on ventilator[1]

Considerations

  • Deeper sedation associated with prolonged ICU stay, increased 6 month mortality[2]
  • Dexmedetomidine or propofol sedation may reduce ICU stay, time on ventilator, when compared with benzodiazepines[3]
    • SCCM Recommendation, level 2B (weak recommendation)[4]
