    Transcript
    Now, what about the treatment for ischemic stroke? Well, in ABCs, you always want to make sure that you’re able to take care of the airway, the breathing, and circulation. That’s always going to be the issue with stroke. Now, with your blood pressure control, you want to keep in mind with systolic blood pressure between, let’s say, 180 and 220. And then if it’s a diastolic blood pressure, you may be approximately 140 to about 120. You want to be less than that so that you’re able to manage your patient who has suffered a stroke. Antiplatelet therapy, aspirin. Anticoagulation. If, if, the patient luckily is the hospital, heparin has to be instituted and helps and hurts, only used in atrial fib and dissection. So be careful. If your patient is already in a state of vulnerability, is already in the state of maybe bleeding, and if your patient is not suffering from atrial fibrillation or dissection, then be really careful with heparin. It’s rapidly acting, works through antithrombin III. And it might actually hurt the patient, may result in a hemorrhagic stroke, so be careful with heparin, please. Also, thrombolytics. I’m going to walk you through tPA, very, very important. And I want to walk you through this. I’m going to walk you through a great detail as to the contraindications for TPA that you must know for your boards. And then rehab. I promised you that we’d come back to the indications for tissue plasminogen activator. Remember that the physiology behind your tPA is the fact that plasmin is an “enzyme” that breaks down your fibrin clot very, very quickly. In other words, it’s a thrombolytic agent physiologically or homeostatically. And of course, we used this to our advantage in which we can then try to break...

    Decent but flesh out the management
    By Hamed S. on 16. March 2017 for Ischemic Stroke: Treatment

    I enjoyed the series on ischaemic stroke but it would have been great to discuss in more depth the secondary management of stroke in particular blood pressure targets and agents with the most supportive evidence for use (e.g ACE-I). I also note that there was an omission about the best way to manage BP in the acutely hypertensive patient post stroke. Despite theses as always good taster of the topic. I appreciate the challenge of work that goes into producing these contents
