Nursing careĪ patient receiving heparin therapy will need to be monitored for bleeding.Ĭheck out this real-world dosage calculation example for administering heparin.
Protamine sulfate is a basic protein derived from fish sperm that binds to heparin to form a stable salt. Protamine sulfate is a medication used to reverse and counteract the effects of heparin. The H in Heparin looks like two Ts put together, to remind you to monitor aP TT with Heparin Antidote for heparin To learn more about these lab values and many more, check out our lab values flashcards for nursing students! A PTT level above 80 seconds means there is too much anticoagulation and we should reduce the dosage. When on an anticoagulant like heparin, PTT levels should be 1.5 to 2 times the normal baseline of 30 to 40 seconds. A partial thromboplastin time (PTT) test measures the time it takes for a blood clot to form in the body. When administering heparin, it’s important to monitor a patient’s PTT levels. Because the body is using all these clotting factors for microclots, the patient is at an increased risk for bleeding.Ī patient who experiences HIT can never again have any form of heparin! aPTT Levels These microclots travel all over the body and cause ischemia to the appendages, turning toes and fingers black from lack of blood flow that can eventually cause them to fall off. It can be confusing, because in this condition, heparin does the opposite of what it’s supposed to do-it’s supposed to decrease clotting, but in HIT it causes microclots.
HIT is a very serious complication where a patient forms microclots. HIT is marked by a 50%+ reduction of platelets from the patient's baseline, so we need to monitor their thrombocyte count closely.
Heparin can also cause something called heparin-induced thrombocytopenia (HIT) which leads to decreased platelet counts. Immune hypersensitivity is also a possible side effect when using heparin. If a patient is given too much heparin, or if it’s working too well, bleeding and bruising will occur. It prevents new clots from forming and existing clots from getting any bigger, but it will not break down clots. It blocks our blood clotting mechanism by inactivating the major clotting protein thrombin. Heparin works by activating antithrombin, which is a naturally occurring protein in the bloodstream that prevents us from clotting too much.
PROTAMINE SULFATE ANTIDOTE SKIN
A subcutaneous injection is a shot given directly into the fat layer between the skin and muscle and allows a drug to be absorbed slowly over a period of time.Įnoxaparin (Lovenox) is low molecular weight heparin used to treat and prevent the formation of blood clots but is only given subcutaneously and not through an IV. Heparin is a drug that can be administered through an IV or through a subcutaneous injection. It is also used to prevent blood clotting during open-heart surgery, bypass surgery, kidney dialysis and blood transfusions. Heparin can be used for things such as a stroke, a deep vein thrombosis (DVT), a pulmonary embolism (PE) or other thromboembolic disorders that require fast anticoagulation. Anticoagulants make blood flow more freely. Heparin is an important anticoagulant medication used to treat and prevent blood clots from forming in people who have certain medical conditions or who are undergoing certain medical procedures.
