International Normalized Ratio Test?

Coumadin (non specific name: warfarin) is an anticoagulant, or blood diminishing drug, that is endorsed to numerous patients who are at danger for creating blood clusters that could bring about heart assaults or strokes. Warfarin is near the most astounding purpose recently and simultaneous investigations of medications that provoke ER visits and occurring an expansion in healing center based offices with the affirmation of patients. Anticoagulation treatment stances perils to patients and over and over prompts unfavorable solution events in light of complex dosing, fundamental ensuing watching, and clashing patient consistence. As a result, various patients who meet current evidence based principles for warfarin treatment are not being managed

This test is appropriate for the doctor to order because it may indicate why Tim is feeling fatigued.

Anticoagulant therapy will started according to facility protocol. This therapy will decrease the blood’s ability to clot, and help to prevent the formation of new clots. Anticoagulants used will be warfarin, heparin, or coumadin. In facility therapy will be initiated via IV push according to facility protocol, with continuous monitoring of patient condition.

This test is often used to see if you have been exposed to viruses or other infectious substances. It is frequently used to screen for present or past infections.

Anticoagulants are a type of drug that reduces the body’s ability to form blood clots in the blood by inhibiting the production of vitamin K in the liver. The goals of the anticoagulant therapy are to prevent stroke in patients with atrial fibrillation and artificial heart valves. In patients with PE/DVT, the primary goal of the anticoagulant is to prevent an existing clot from getting larger. Anticoagulant drugs can be used after surgery to prevent new blood clots. Anticoagulant drugs increase the risk of bleeding. Because of this risk, it is essentially important to educate the patient to take the medication exactly as directed and never take larger or more frequent doses. The challenges of anticoagulant therapy are to keep it in the therapeutic

Atrial fibrillation is the most frequent cardiac arrhythmia. There has always associated risk of clot formation and embolization that can lead to ischemic stroke. A large number of these ischemic events could be prevented by timely anticoagulation. Warfarin has been used for decades for this purpose, but there are many problems for the patients due to warfarin therapy like there is continuous need of INR monitoring, many food and drug interactions of the drug, late onset of action and risk of major bleeding. Anticoagulation with the Novel oral anticoagulants e.g. Dabigatran, rivaroxaban, apixaban, endoxaban led to similar or even lower rates of ischemic stroke and major bleeding compared to an adjusted dose of warfarin (INR 2-3) in patients

Information to patient: Clopidogrel is an antiplatelet medication. Platelets are small blood cells that clump together during blood clotting. Prevent clotting of platelet to prevent unwanted blood clots after heart attack or stroke. Decreases risk of cardiovascular events but increases the risk of major bleeding. Swallow the tablet with a glass of water. Taken with or without food as directed by doctor. Taking the tablet at the same time each day has the best effect. It will also help you remember when to take it. Avoid this medication if active bleeding present in GI tract. Do not stop clopidogrel suddenly.

Rates of major bleeding were significantly lower for apixaban when compared to warfarin.(Schwarz UI, Ritchie MD, Bradford Y, et al.

Warfarin and novel anticoagulants are increasingly utilized for the prevention of clotting in various increased risk disease states or anatomic changes including atrial fibrillation, the presence of artificial heart valves, and development of repeated deep venous thromboses (1-3). While the potential benefits of anticoagulation are useful, the risk of hemorrhage increases significantly (4). The incidence of major bleeding has been estimated at 1–3% annually and is even greater when the international normalized ratio (INR) is greater than 4.5 (4). Coinciding with the increased utilization of anticoagulant medications is the increasing incidence of emergency general surgery (EGS) disease such as acute cholecystitis, peptic ulcer

Thromboelastography also known as TEG is a serum laboratory test that determines coagulation of blood. Blood clotting is called hemostasis and is an active, extremely complex process, involving many interacting factors including clotting, fibrinolytic proteins, activators, inhibitors and cellular elements (Eitel, 2012). It can help in determining if a patient may have a clotting factor or anemia by looking at clot strength and fibrinolysis. The test is usually utilized for surgery and anesthesia and does not replace other serum coagulation tests such as prothrombin time (PT,INR) or partial thromboplastin time (aPTT). TEG is able to assess platelet function, clot strength, and fibrinolysis where these other tests cannot.

Warfarin is a very common used drug worldwide. Warfarin is used to prevent harmful blood clots from forming or growing larger. Beneficial blood clots prevent or stop bleeding, but harmful blood clots can cause a heart attack, stroke, deep vein thrombosis or pulmonary embolism. Although warfarin is commonly used, its management is very challenging. First, it has a very narrow therapeutic index- increased anticoagulant effect puts the patients at a risk of bleeding, while decreased anticoagulant effect puts them at a risk of thromboembolic disorders such as heart attack and stroke. And second, the wide variation among patients in drug response. Therefore, it needs long time to determine the adequate dosage for each patient. Complications from inappropriate warfarin dosing are among the adverse events most frequently reported to the US

Coagulation tests measure functions that are related with clotting, coagulation consists of drawing blood and observing it clot. Chelating out the calcium and beginning the clot in a controlled environment. Coagulation tests used to find out if an individual has a clotting disorders and to measure the various proteins and how they function. There are many conditions that can causes problems with coagulation for example thrombophilia and haemophilia. (TRANSFUSION MEDICINE AND HEMOSTASIS BOOK)

A considerable number of diagnostic tests ordered by teaching hospital can be considered unnecessary (Schroeder, Kenders et al. 1973, Eisenberg, Williams et al. 1977, Williams and Eisenberg 1986, Dorizzi, Dall 'Olio et al. 1996). Redundant test ordering is expensive resulting in excessive false-positive outcomes, leading to further causeless testing, treatment and expenses (Bates, Goldman et al. 1991).

If a blood clot causes the blood flow to be restricted to the brain, a stroke can occur. Heart attacks happen when blood flow to the heart becomes blocked and even kidney failure can occur due to a clot in the kidneys. During pregnancy, blood clots can cause miscarriages, stillbirths, and preeclampsia, high blood pressure during the pregnancy. People with this condition can manage it with proper care (“What is..). Excessive blood clotting can be treated with medicines, but a person may need emergency treatment depending on the location and size of the clot. A person with excessive blood clotting may be prescribed blood thinners, or anticoagulants, to keep existing clots from becoming larger and to prevent new clots from forming. Blood thinners can be taken in pill form, through an IV injection, or through a regular needle. Warfarin is the name of the pill form and heparin is given as an injection or through the IV tube. In comparison to one another, Warfarin takes several days before it works and Heparin acts quickly, so the doctor may treat the patient with both treatments until Warfarin begins to work. There are short-term treatments as well for this condition. Antithrombin factor is used in special situations, such as before surgery, or if a person has antithrombin deficiencies. Protein C may also be given to people before they begin taking Warfarin to protect them from damage to their skin cells if they have protein C

Patient 2 was a 65 year old female who had arrived with her blood test request form for a coagulation screen, which includes INR (prothrombin time), APTT (activated partial thromboplastin time) and fibrinogen. A prothrombin test measures how long it takes for blood to clot, or, coagulate. APTT is a screening test done which evaluates the function of a patient’s intrinsic clotting system, the factors of prothrombin and fibrinogen that are involved, as well as prekallikrein (PK) and high molecular weight kininogen (HK). Additionally, Patient 2’s heparin anticoagulant therapy needed to be monitored; heparin being an anticoagulant which is administered intravenously or by injection in order to treat blood clots. A single CITRATE tube of the colour light blue was used for the patient’s blood collection; this tube contains sodium citrate as an anticoagulant and is used for drawing blood for the purpose of coagulation studies.
