The INR may offer predictive capabilities to the attending doctor in resource-depleted environments. Elevated international normalised ratios correlate with severity of injury and outcome. Effects of a standard dose of fresh frozen plasma on various elevations in the international normalized ratio.
The successfully communicated INR critical results to the responsible caregivers were calculated as the number successfully communicated within the clinical laboratory's established time frame over the total number identified. Mean INR levels dropped from 2. Dicloxacillin may cut INR levels in warfarin users. After reviewing all of the medical evidence on point-of-care INR testing for patients taking warfarin, an expert panel agreed that point-of-care INR testing is accurate.
Even so, rounding out your existing knowledge with some additional medical terms, abbreviations, and acronyms can help you gain an even better handle on what you hear in the health care world. This list can help you get started. Breaking down common medical terminology. The world of medical terminology is quite vast, so this list is organized by category to make it a little easier to digest.
The charts providers use for making notes are often filled with this kind of medical terminology. You might even know some of them by a different name. Abscess : A tender, fluid-filled pocket that forms in tissue, usually due to infection. Acute : Signifies a condition that begins abruptly and is sometimes severe, but the duration is short. Benign : Not cancerous. Chronic : Signifies a recurring, persistent condition like heart disease. Contusion : A bruise.
Defibrillator : A medical device that uses electric shocks to restore normal heartbeat. Edema : Swelling caused by fluid accumulation. Embolism : An arterial blockage, often caused by a blood clot. Epidermis : The outer layer of the skin. Fracture : Broken bone or cartilage. Gland : An organ or tissue that produces and secretes fluids that serve a specific function. Hypertension : High blood pressure. Inpatient : A patient who requires hospitalization. Malignant : Indicates the presence of cancerous cells.
Outpatient : A patient who receives care without being admitted to a hospital. Prognosis : The predicated outcome of disease progression and treatment. Relapse : Return of disease or symptoms after a patient has recovered. Sutures : Stitches, which are used to join tissues together as they heal. Transplant : The removal of an organ or tissue from one body that is implanted into another.
Vaccine : A substance that stimulates antibody production to provide immunity against disease. Zoonotic disease : A disease that is transmissible from animals to humans. Medical terminology follows the same structural rules all language does, including use of prefixes and suffixes. You may be familiar with some of these from words outside the realm of medicine.
A-, an- : Lack of or without. Dys- : Abnormal, difficult, or painful. Macro- : Large in size. Micro- : Small in size. Poly- : Many. INR values over 4. Evidence suggests that more frequent testing will result in more time within the desired INR target range. Monitoring then occurs every 2—3 days for the next few weeks, and then with decreasing frequency depending on the stability of the results. If the INR remains stable, testing can be spread as far apart as every four weeks.
Many medications, foods and even concurrent illness are known to interact with warfarin and therefore interfere with the INR.
These affect the way warfarin is processed by the body. Therefore, you should consult your doctor if you:. The desired INR depends on the reason why you need anticoagulation. The three most common reasons for warfarin use, along with their target INRs, include:.
INR can be monitored either by laboratory blood testing or by using a portable monitoring device. Laboratory blood testing is the traditional practice in Australia.
Blood is drawn from a vein, typically by a GP, and sent to the laboratory for testing. There is a time delay before results are returned to the GP, who analyses the need for dose adjustment with the help of computerised algorithms. The practitioner will then let you know whether a dose adjustment is needed. A dose adjustment will be required if your INR value for the test is outside the therapeutic range too high or too low. Portable devices, introduced in the s, allow you, your doctor or another health practitioner e.
The blood drop is placed on a test strip which is inserted into the portable device so that the clotting time can be measured. These devices have been demonstrated accurate and reliable and to provide reproducible results which are similar to those obtained through laboratory testing. If the device is used for monitoring in a health facility, a health practitioner often a nurse conducts the blood test and records the result on your behalf.
In consultation with the doctor prescribing warfarin or based on a computerised algorithm, the health practitioner can notify you immediately if any dose adjustments are necessary. Benefits have been associated with this testing method.
In particular, obtaining on the spot results enables better management of oral anti-coagulation therapy, as dose adjustments can be made immediately and discussed with the health practitioner face to face rather than over the phone. Some people also prefer not needing to have blood drawn from a vein using a needle with this method.
When a portable device is used for home monitoring, you usually conduct the test yourself. However, in some countries health practitioners can visit you in your homes or aged care settings to conduct blood monitoring.
This enables you to have your INR monitored without the inconvenience of attending a healthcare facility. Self-testing has the advantage of being more convenient and making it easier for you to take the correct dose of warfarin at the correct time. People who use this method are more likely to monitor their INR more frequently. They are also less likely to experience blood clot or bleeding complications.
