|
S/S of Increased ICP
|
Headache
Pupillary Changes N/V Papilledema Seizures Vital Sign changes-LATE s/s of IICP: Cushing's Triad *Bradycardia, bounding *Bradypnea, irregular *Increased systolic pressure w/ widening pulse pressure. |
|
|
Circulating BV is increased by:
|
Increase CO2
Decreased O2 Aneurysm Arteriovenous malformation |
|
|
CSF is increased by?:
|
hydrocephalus
|
|
|
Osmotic Diuretics - Mannitol
Actions |
Withdraws fluid from NORMAL tissues.
Works in approx. 20 mins May cause rebound cerebral edema. |
|
|
Loop Diuretics - Furosimide (Lasix) Actions
|
Reduce the rate of CSF production.
|
|
|
Corticosteroids - Decadron Actions
|
Stabilizes cell membranes
Only documented effectivess is with brain tumors. |
|
|
Treating Increased ICP: BP control interventions
|
Avoid HTN and HypoTN
Keep systolic BP <160mm Hg *May require higher BP for management of vasospasms that are associated with subarachnoid hemorrhage |
|
|
Treating Increased ICP: Fluid Restriction
|
75-100 mL/hr
|
|
|
Treating IICP: Control cerebral metabolism
|
Treat Fever
Prevent Seizure activity Sedation Neuromuscular blockade |
|
|
Treating IICP: Induce barbiturate coma -- pentobarbitol
|
Decreases tissue metabolism
Decreases cerebral edema Best used EARLY to manage ICP that is not responding to standard tx. |
