2025 Multiprofessional Critical Care Review: Adult Online-Sedations Analgesia

Video Transcription

Video Summary

Dr. Chai Winchester’s lecture on sedation analgesia covers ICU patient agitation, sedation scales, delirium types, sedation strategies, and key medications. Agitation affects about 70% of ICU patients, increasing complications and length of stay. The Richmond Agitation Sedation Scale (RASS) targets a calm, alert state (score zero). Delirium may be hyperactive, hypoactive, or mixed, detected via CAM-ICU. Best sedation practices emphasize daily interruption and light sedation to improve outcomes. Non-pharmacologic methods like orientation and early mobilization help prevent delirium. Common sedatives discussed include benzodiazepines (linked to higher delirium risk), propofol (no analgesia, risk of infusion syndrome), dexmedetomidine (alpha-2 agonist, sedation without respiratory depression), opioids (fentanyl, morphine), ketamine, and etomidate. Morphine has active metabolites with seizure risk. Antipsychotics do not prevent delirium but may treat symptoms. The SCCM guidelines recommend prevention focusing on pain control, sedation interruption, early mobilization, and preferred use of dexmedetomidine when needed.
