Stop strokes and heart attacks before they stop you!
The .79 ¢ LIFE-SAVER that your doctors
NEVER tell you about!
I really hope this video helps you out a ton! This medication is one of the major ones you will see in adult Med Surg & Critical care. Although it saves lives, we have to be very careful when taking care of patients with clotting tendencies.
Furthermore, we must also educate our patients about diet restrictions, safety precautions and the importance of their follow up appointments.
I hope this video simplifies at least a little bit of it 😉
Also, remember… you can access the audio of the video to download on your device, so that not matter where you are, you can always be learning.
If you prefer to watch the video without any music, you can go to my website… you will also find the audio there:
I hope this & all of the videos help you tremendously.
Warfarin aka Coumadin is the most used oral anticoagulant in the world and has been used for more than 50 years for therapy in prevention of thrombus formation and subsequent thromboembolic events. Anticoagulants are blood thinners which prevent formation of blood clots as well as prevent existent blood clots from increasing in size. Blood clots can hinder blood circulation and lead to serious medical conditions, like stroke, heart attack and pulmonary embolism. Thus warfarin is helpful in treating and preventing vein and artery blockage, stroke and heart attack.
Mechanism of Action
Warfarin slows down the formation of blood clots within 24 hours, but the complete effect takes place between 72 to 96 hours after taking the medication. Blood clot formation is a
complicated process which requires certain compounds known as coagulating factors to be present. These coagulating factors are produced by the liver. In the presence of sufficient vitamin K. Warfarin acts by inhibiting the presence of vitamin K and this inhibits the formation of coagulating factors. Substances that require vitamin K for their formation are: the anticoagulant proteins C and S and factors II, VII, IX, and X. Therefore, medications like warfarin block coagulating factors and disturb the process of clot formation. Thus slowing down blood clot formation. In the case of blood clots that are already formed, warfarin stops the clot from getting bigger. It also prevents breakage of the clot which can be otherwise dangerous if it travels in the bloodstream and blocks blood vessels. Warfarin cannot destroy or dissolve a blood clot that is already there. But the blood clot itself may slowly dissolve with time. Nor can Warfarin reverse ischemic tissue damage either, but, may help avoid secondary thromboembolic complications that can be dangerous and even fatal.
Warfarin (Coumadin) is indicated for/to:
• Prophylaxis, pulmonary embolism (PE), venous thrombosis and its extension, and to prevent blood clots from moving to other parts of the body.
• Reduce the risk of another stroke or heart attack in clients who already have had stroke or heart attack, and to reduce the risk of death.
• Prevent and treat blood clots associated with atrial fibrillation (irregular rapid heartbeat), heart-valve replacement and blood clots in lungs and legs.
