What is the tie-frame for alteplase to be given
- within 3 hours of symptom onset
- within 4.5 hours of symptom onset in select patients
- within 60 min of hospital arrival
Alteplase and BP
BP should be < 185/110 mmHg before initiating alteplase - can lower BP to be given alteplase
-keep BP < 180/205 for the first 24 hours after tx
Bleeding contraindications to alteplase
-active bleed (ICH)
-conditions or labs that increase bleeding (INR > 1.7)
-drug interactions with bleeding risk
Contraindications to alteplase
-active internal bleeding
-hx of recent stroke
- severe uncontrolled HTN
- prior ICH
- labs that indicate bleed
-conditions that increase bleeding risk
-tx of LMWH within 24 hours , use of direct thrombin inhibitor or direct factor xa inhibitor within the previous 48 hrs
dosing of alteplase
0.9 mg/kg (maximum dose 90 mg)
ASA
ASA 162-325 PO within 24-48 hours after stroke onset is recommended (should not be given within 24 hours of fibrinolytic therapy)
HTN management
antihypertensives should be given to lower BP to give alteplase and to maintain BP for at least 24 hours after infusion.
-those who do not receive alteplase therapy may not require antihypertensive therapy unless severelt uncontrolled
hyperglycemic management
140-180
DVT ppx
SCDs or LMWH (after 24 hrs if treated with alteplase)
Secondary prevention: HTN
goal < 130/80 mmhg
Secondary prevention: HLD
high intensity statin - atorvastatin 80 mg
