Assessment of sedation in the TICU

1 minute read

Why sedate in the ICU?

  • Patients in the TICU are in pain and uncomfortable
  • Sedatitives reduce anxiety, decrease awareness of unpleasant stimuli, induce sleep.
    • They do not address pain, although some pain medications can assist or influence sedation level.
    • Amnesia
      • good for procdures
      • patients on paralytics
    • Safety and agitation
    • Ventilator tolerance
    • sleep deprivation
    • Anxiety/Fear
    • Delirium

Assessing sedation level

  • The Richmond Agitation-Sedation Scale (RASS) is a reliable way to quantify level of sedation in the ICU patient (Ely_Etal_2003).
Score Term Description
-5 Unarousable No response to verbal of physical stimuli
-4 Deep sedation No response to voice but response to physical stimuli
-3 Moderate sedation Movement or eye opening to voice but no eye contact
-2 Light sedation Awakens for <10 seconds and brief eye contact
-1 Drowsy Sustained awakening >10 seconds
0 Alert and calm  
1 Restless Anxious
2 Agitated Fights vent
3 Very agitated Pulls at tubes, aggressive
4 Combatitive violent
  • Goal RAAS is -1 to 0.
