mentation change work up

Question 1

what do you do once you have history and signalment

Answer 1

decide if its systemic dz vs neurologic by TPR and neuro exam

Question 2

formula for cerebral perfusion pressure

Answer 2

MAP-iCP=CPP

Question 3

if primary neurologic what is our concern about maintaining CPP

Answer 3

if the intracranial pressure gets too great we can decrease perfusion to the brain. which would cause ischemia

Question 4

what are signs of increased intracranial pressure

Answer 4

miosis or mydriasis
tetrapariesis
cranial nerve or proprioceptive deficits
bradycardia

Question 5

how does the body compensate for a increased ICP

Answer 5

increasing map= becuase pa CO2 was too high

this causes vagal tone response to high MAP and causes bradycardia

Question 6

how do we decrease ICP

Answer 6

decrease edema; mannitol hypertonic saline fast

craniectomy
remove tumor or lesion

Question 7

what are things we can give/treat in a mentation change patient

Answer 7

get TPR CBC/CHEM and fix all abnormalitities
fluids, electrolytes, warm up temp, oxygen
