SCORES DE SEDATION


Voici 4 scores de sédation dont les propriétés ont été correctement étudiées et qui peuvent être utilisés en routine ou dans une étude sur la sédation.
 
Ramsay Scale
Awake levels
patient anxious or agitated or both1
patient co-operative, orientated and tranquil2
patient responds to commands only3
Asleep levels :
a brisk response to a light glabellar tap4
a sluggish response to a light glabellar tap5
no response6
Echelle de sédation très employées en France car très simple
Reproductibilité très correcte (Kappa: 0.79 à 0.87) validité testée contre le S.A.S.

Comfort Scale
Altertness :
Deeply asleep1
Lightly asleep2
Drowsy3
Fully awake and alert4
Hyper-alert5
Calmness/Agitation :
Calm1
Slightly anxious 2
Anxious3
Very anxious 4
Panicky 5
Respiratory response :
No coughing and no spontaneous respiration1
Spontaneous respiration with little or no response to ventilation2
Occasional cough or resistance to ventilator3
Actively breathes against ventilator or coughs regularly4
Fights ventilator; coughing or choking5
Physical movement :
No movement 1
Occasional, slight movement2
Frequent, slight movement3
Vigorous movement limited to extremities4
Vigorous movement including torso and head5
Blood pressure :
Blood pressure below baseline1
Blood pressure consistently at baseline2
Infrequent elevations of 15 % or more (1-3 episodes)3
Frequent elevations of 15 % or more (more than 3 episodes)4
Sustained elevation ≥ 15 %5
Heart rate :
Heart rate below baseline1
Heart rate consistently at baseline2
Infrequent elevations of 15 % or more (1-3 episodes)3
Frequent elevations of 15 % or more (more than 3 episodes)4
Sustained elevation ≥ 15 %5
Muscle tone :
Muscle totally relaxed 1
Reduced muscle tone2
Normal muscle tone3
Increased muscle tone and flexion of fingers and toes4
Extreme muscle rigidity and flexion of fingers and toes5
Facial tension :
Facial muscle totally relaxed1
Facial muscle tone normal; no facial muscle tension evident2
Tension evident in some facial muscles3
Tension evident throughout facial muscles4
Facial muscles contorted and grimacing5

Sedation - Agitation Scale (SAS)
Dangerous agitation. Pulling at ET tube, trying to remove catheters, climbing over bed rail, striking at staff, trashing side-to-side 7
Very agitated. Does not calm, despite frequent verbal reminding of limits, requires physical restraints, biting ET tube 6
Agitated. Anxious or mildly agitated, attempting to sit up, calms down to verbal instructions 5
Calm and co-operative. Calm, awakens easily, follows command 4
Sedated. Difficult to arouse, awakens to verbal stimuli or gentle shaking but drifts off again, follows simple commands 3
Very sedated. Arouses to physical stimuli but does not communicate or follows command, may move spontaneously 2
Unrousable. Minimal or no response to noxious stimuli, does not communicate or follows command 1
Echelle assez proche du Ramsay.
Excellente reproductibilité (Kappa 0.91) . Validité testée face au Ramsay et à l'echelle de Harris.

Motor Activity Assessment Scale (MAAS)
Unresponsive. Does not move with noxious stimulus0
Responsive only to noxious stimuli. Open eyes OR raises eyebrows OR turns toward stimulus OR moves limb with noxious stimulus 1
Responsive to touch or name. Open eyes OR raises eyebrows OR turns head toward stimulus OR moves limb when touched or name is loudly spoken 2
Calm and co-operative. No external stimulus is required to elicit movement AND patient is follows command 3
Restless and co-operative. No external stimulus is required to elicit movement AND patient is picking at sheets or tubes OR uncovering self and follows command 4
Agitated. No external stimulus is required to elicit movement AND attempting to sit up OR moves limbs out follow commands (e. g. ; will lie down when asked but soon reverts back to attempts to sit up or move limbs out of bed) 5
Dangerously agitated, uncooperative. No external stimulus is required to elicit movement AND patient is pulling at tubes or catheters OR trashing side to side OR striking at staff OR trying to climb out of bed AND does not calm down when asked 6
Echelle tres proche de la précédente.
Reproductibilité testée sur 400 paires de mesure (Kappa 0.83) validité bien testée face aux experts.
Sensibilité aux changements non testée
