IICP Flashcards
Decreased LOC early manifestations
confusion, restlessness, lethargy
disorientation
normal ICP
5-15mmHg
decreased LOC late signs
comatose with no response to painful stimuli
motor impairments early signs
hemiparesis or hemiplegia (paralysis) of contralateral side
motor impairments late signs
abnormal responses (decorticate or decerebrate) flaccidity
earliest manifestations of increasing ICP
changes in cortical function
cushing’s triad
widening pulse
bradycardia
hypertension
contraindicated diagnostic test
lumbar puncture
sudden release of pressure in skull may cause cerebral herniation
increase osmolarity of blood
drawing water out of edematous brain tissue and into vascular system for elimination via kidneys
osomotic diuretics
:mannitol
initiated if pt has exceeded 15-20mmHg for atleast 10min
dont admin with blood products
mannitol
osmotic diuretics interventions
monitor output every hr
monitor for s/s of dehydration
assess for muscle weakness, numbness, tingling, paresthesia
renal function/ electrolytes
reduce rate of CSF production
:monitor BP and PR before admin
:monitor renal labs
loop diuretics
:lasix
ICP is stable as long as volume added is balanced by volume displaced
3 components must be in equilibrium
CSF, Blood, Brain Tissue
Monroe-Kelly Hypothesis
Turning pt interventions
turn pt
wait 2min for ICP to return to prior turning pressure
***If ICP doesnt return, turn pt on back
client teaching
avoid coughing, blowing nose, valsalva avoid isometric (muscle contracting) exercises maintain head alignment
