Assessment of sedation in the TICU
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.
