Vomiting: occurring from pressure in thebrainstem
Seizure
Cushings triad
7/28/2019 c Tests(Neuro)
139/233
Increased SBP: results from ischemia of the vasomotor center , which thenreleases a general sympathetic
discharge.
Bradycardia: because heart is trying to
7/28/2019 c Tests(Neuro)
140/233
to pump blood into cerebral vessel with
extreme high resistance.
Hyperthermia: results from hypothalamicdysfunction but may be due to infection.

- result from hypothalamic stimulationfro ICP with resulting vagal activation.The ulcers results from increasedserum gastrin levels, which stimulateshypersecretion of HLC acid.
Management
7/28/2019 c Tests(Neuro)
142/233
1. Surgery: removal of the cause, or decompression.2. Fluid restriction: kept slightlydehydrated to reduce ICP, 800 ml/dayonly.3. Positioning: Head elevation- toassist on venous return fromintracranial circulation and preventfurther congestion.
7/28/2019 c Tests(Neuro)
143/233
4: Meds:MannitolCortecosteroids( dexamethasone)- iseffective in reducing vasogenicedema
AntacidStool softener( docusate sodium:colace)- to prevent straining
Acetaminophen: reduce temperature
7/28/2019 c Tests(Neuro)

Classification of Brain Attacks:
Ischemic (emboli, Thrombus)Hemorrhagic
Pathophysiology
7/28/2019 c Tests(Neuro)
169/233
An abrupt interruption of circulationfro 4-8 minutes will producepermanent brain damage, because
neurons are unable to regenerate.
When circulation to an area isimpaired gradually collateral
7/28/2019 c Tests(Neuro)
170/233
impaired gradually, collateral
circulation is often able to developand maintain an adequate supply of blood to that area of the brain.
Once infarction occurs, the damage is
7/28/2019 c Tests(Neuro)
171/233
girreversible. Cellular death occur within 5 minutes. Symptoms such asLOC occurs when oxygen isinterrupted fro 10 seconds butirreversible when circulation isreestablished.
