  3. Anticoag if cardioembolic
41
Q

fyi

42
Q

Hemorrhagic strokes account for __% of strokes. They include spontaneous ICH and SAH.

A

20%

*Spontaneous ICH- MC from HTN. Treatment is supportive v. hematoma evacuation. Elevate head and mannitol!

to distinguish from CVA

64
Q

How are migraines managed?

A
  1. Triptans or Ergotamines
  2. Dopamine blockers- Reglan, Phenergan. If giving these antiemetics for N/V you want to give with Benadryl to prevent EPS, dystonic rxns, and parkinsonism symptoms due to decreased dopamine.
