Evaluation of the Obtunded Patient
First Things First (assess & treat for the following)
ABCs
- Airway assessment     
- Altered mental status may indicate compromised ability to protect airway.
 - GCS 8 or less requires airway protection (eg, ETT).
 
 
Glasgow Coma Scale
- Motor         
- 6 = Appropriate
 - 5 = Localizes to pain
 - 4 = Nonpurposeful
 - 3 = Decorticate posturing: upper extremities flex, lower extremities extend
 - 2 = Decerebrate posturing: fully extends
 - 1 = No movement
 
 - Eye Opening       
- 4 = Spontaneous opening
 - 3 = Opens to stimulation
 - 2 = Opens to strong stimulation
 - 1 = Does not open
 
 - Speech        
- 5 = Appropriate
 - 4 = Confused
 - 3 = Inappropriate words
 - 2 = Incomprehensible sounds
 - 1 = No response
 
 - Breathing           
- Alterations in breathing pattern may indicate site of lesion.
 - Mechanical support may be required to maintain adequate ventilation & oxygenation.
 - Circulation (see Circulation)      
- Goal is to maintain cerebral perfusion pressure (CPP) at least 60 mmHg.
 - If ICP is unknown, then goal of MAP >90 mmHg until ICP can be determined
 - General physical exam
 
 - Other clinical exams as directed by clinical suspicion
 - Focused history & general medical exam
 - ICU neuro exam   
- This MUST be performed w/ attention to detail!
 
 - Treat immediate conditions.   
- Seizures, herniation, malignant hypertension, etc.
 
 - Appropriate diagnostic tests   
- Neuroimaging (eg, CT or MRI), EEG, labs, etc.
