PROCEDURE FOR SEDATION SCORING USING VAMASS

Sedation is ordered and evaluated using the Ventilator Adjusted Motor Assessment Scoring Scale (VAMASS) described below:
 
Procedure
Rationale
1.
Establish patient specific Ventilation Adjusted Motor Assessment Scoring Scale (VAMASS) goal as per scale below.  Identify motor and ventilation scale and report as 3A, 5C, 2B etc.

The VAMASS goal or target is to be established for each patient and included in sedation orders. The VAMASS goal will be reviewed during patient care rounds and prn.  The VAMASS goal should be recorded on the Kardex and 24-hour assessment record (CCTC).

Note: the VAMASS should be reassessed and modified prn.  For example, if the initial goal is 3A, but he patient cannot be maintained at this level, a more appropriate score should be selected.

Score all patients who are receiving sedation or who are mechanically ventilated or receiving sedatives (e.g. midazolam, propofol, haloperidol). If the patient is not on the ventilator, assess the motor portion of the score and report as 3, 2, or 4 instead of 3A, 2B or 4B).

Do not score patients receiving neuromuscular blocking agents.
 

1. To evaluate the level of sedation.
 
 

To identify the most appropriate level of sedation and communicate to other members of the health care team.
 
 
 
 
 
 
 

Motor function assessment is contraindicated in patients receiving neuromuscular blocking agents; patients may feel pain but would be unable to respond.

VENTILATOR ADJUSTED MOTOR ASSESSMENT SCORING SCALE (VAMASS)


MOTOR SCORE
ASSESSMENT FINDING
VENTILATION SCORE
ASSESSMENT FINDING
0
Does not move to noxious stimulus.
A
Minimal coughing, comfortable respiratory rate, minimal high pressure or rate alarms.  Tolerates movement and stimulation.
1
Opens eyes OR raises eyebrows OR turns head towards stimulus OR moves limbs with noxious stimulus.
B
Coughing and high respiratory rates when stimulated but settles with voice or removal of stimulation.
2
Opens eyes OR raises eyebrows OR turns head towards stimulus OR moves limbs when touched or name is spoken.
C
Distressed, frequent episodes of coughing and competing with ventilator, high rates with normal or low PCO2s, frequent high pressure alarms.
3
No external stimulus is required to elicit movement AND patient is adjusting sheets or clothes purposefully and follows commands.
D
Unable to control ventilation, high airway pressures or difficulty delivering adequate volumes or prolonged coughing.
4
No external stimulus is required to elicit movement AND patient is picking at sheets or tubes OR uncovering self & follows commands.
5
No external stimulus is required to elicit movement AND patient is attempting to sit up OR moves limbs out of bed AND does not consistently follow commands (e.g. will lie down when asked but soon reverts back to the attempts to sit up or move limbs out of bed).
6
No external stimulus is required to elicit movement AND patient is attempting to sit up OR thrashing side to side OR striking staff OR trying to climb out of bed AND doesn't calm down when asked.

 
 
 
4. Enter "sedation" as a parameter on the Assessment and Intervention flow sheet.  If the charted "plan" maintains the target VAMASS, arrow q4h as per other parameters.

If the plan requires modification or the patent varies significantly from the goal, complete a DAR note (e.g. additional sedation is ordered to achieve the target VAMASS; large doses of sedation are used during a procedure that causes increased sedation).

Note that sedation is a different parameter than "neuro".
 

4. As per protocol for "charting by exception". 

Neurological assessment still needs to be performed to identify any focal or neurological findings.
