If the INR is greatly above 8. Haemorrhage can occur even when the INR is within its intended range. For bleeding patients, the severity of haemorrhage governs whether or not warfarin reversal treatment is used and the type of treatment — not the INR level.
Minor bleeding would include patients who present with bruising or epistaxis of limited duration. Anticoagulated patients who are experiencing minor bleeding should have their warfarin doses omitted and be given 2mg of oral phytomenadione. If the patient has a significantly high INR above 8. Major bleeding can be subdivided into two categories.
First is haemorrhage that poses a risk to life, limb or sight. This includes intracranial, retroperitoneal, intraocular, pericardial and muscular bleeding. Second is haemorrhage that does not cause major haemodynamic compromise i.
Examples of this include some GI bleeds or continuous epistaxis 2. The aim of treatment should be to arrest the haemorrhage as quickly as possible and stabilise the patient, thereby limiting further harm. The risk of warfarin resistance is less relevant in this situation but must still be considered, particularly for patients at major risk of thrombosis e. PCCs are concentrates of specific amounts of vitamin K-dependent clotting factors obtained from pooled plasma products.
Beriplex, for example, contains therapeutic levels of all four of these factors. Other products contain only three of these factors. However, obtaining patient outcome data for this patient cohort is difficult, due to the urgency with which treatment needs to be administered.
PCCs are recommended for major bleeding that is life-, sight- and limb- threatening. They are particularly useful for treating patients with intracranial haemorrhage. The outcomes for such patients are likely to worsen as the volume of the original bleed and size of the haematoma increase. Drawbacks of PCC include its high cost and its potential for causing infection with unknown pathogens — despite being treated for virus inactivation.
PCC can be thrombogenic and, in particular, can cause disseminated intravascular coagulation see Box. However, this is less of an issue for patients who have been excessively anticoagulated 2. PCC must be administered with 5mg of IV phytomenadione. This restores the ability of the body to manufacture vitamin K-dependent clotting factors, allowing the reduction in INR generated by PCC to be maintained.
Disseminated intravascular coagulopathy is the widespread formation of numerous thrombi in response to a variety of conditions, such as shock or trauma. This results in a reduced ability to form further clots and, therefore, can cause uncontrolled bleeding from, for example, the digestive tract, respiratory tract and any skin wounds.

If you are looking for a particular leaflet and cannot find it on this page, email PatientInformationTeam gstt. This means that we have a strong production process to make sure our information is reliable and easy to understand.
We also use leaflets produced by other trusted organisations. Read more about how we work to inspire confidence and trust in our information for patients. We value feedback on our information as we want to make sure the information you receive is helpful to you.
If you have any comments about our leaflets, we would be happy to hear from you. You can email us patientinformationteam gstt. The prothrombin time test may also be performed to evaluate you for liver disease. It is one of several tests used to screen people waiting for liver transplants. That screening — known as the model for end-stage liver disease MELD — is a scoring system for assessing the severity of chronic liver disease.
If your doctor suspects you have other health issues, such as liver problems or a bleeding disorder, you might need additional testing to confirm your condition. A prothrombin time test is similar to any other blood test. You might experience soreness or minor bruising at the site in the arm where your blood is drawn. Obtaining the blood sample for prothrombin time testing usually takes just a few minutes, like any other blood test. Your blood might be sent to a laboratory for analysis.
If the laboratory analysis is done on-site, you could have your test results within hours. If your doctor sends your blood to an off-site laboratory, it may take several days to receive the results.
In some anticoagulation clinics, a nurse will take a sample of your blood with a finger stick, and give you the test result within minutes, while you are still in the exam room.
Home testing kits are available for people who have to take blood thinners for long periods and who have been trained in taking blood samples and testing them. The average time range for blood to clot is about 10 to 13 seconds.
A number higher than that range means it takes blood longer than usual to clot. A number lower than that range means blood clots more quickly than normal.
This ratio — which allows for easier comparisons of test results from different laboratories — is used if you take blood-thinning medications.
