Stroke: Management Flashcards
1
Q
How should acute stroke be managed?
A
- Keep blood glucose, hydration, oxygen sats and tempearture within normal limits.
- BP should not be lowered unless they are either a candidate for thrombolysis or they have a concomitant medical issue (aortic dissection, MI, pre-eclampsia, end organ problems due to hypertension - kidneys, heart failure etc)
- Give Aspirin 300mg ASAP once haemorrhagic stroke is excluded.
- If AF- only start anticoagulants ~14days after the start of ischaemic stroke.
- Commence on a statin if cholesterol is >3.5mmol/l (BUT ONLY START 48 HOURS AFTER STROKE DUE TO RISK OF HAEMORRHAGIC TRANSFORMATION)
