What is the time of bleeding?
The bleeding time is a medical test performed to assess the effectiveness of the patient's pad and blood blood mechanism. In general, the doctor will use an automatic device to feed a small cut in the patient's body to create a small bleeding, and the individual bleeding time is the time the wound takes to stop the wound completely. The Duke method and the IVY method are two main approaches to performing this test, the second one is more common. While the duke method involves the patient's sting with a needle or similar device, the IVY method is relatively invasive and includes a cut to the forearm. While some drugs can artificially prolong bleeding time, if they are taken shortly before the test, abnormal results may indicate conditions such as thrombocytopenia and von Willebrand's disease.
The Duke method is less commonly used. After cleaning the area with alcohol, the physician writes the patient's fingers with a specialized needle or lancet, usually around 0.1 inches deep (3 to 4 mm). The usual bleeding timeIt is approximately one to three minutes for the Duke method.
According to the Ivy method, the doctor will use spring scalpel blade or lancet to create a cut on the patient's forearm, usually on the underside where there are no visible veins. The standard cut for cut is usually 0.3 inches long (10 mm) and 0.03 inches deep (1 mm) and the sphygmomanometer or blood pressure cuff is placed anywhere above the wound to maintain standardized blood pressure in the veins. The paper will be used to clean the blood area approximately every 30 seconds until the bleeding completely stops. The normal bleeding time for the IVY method is anywhere from two to nine minutes. In all cases, bleeding must be stopped manually if the patient bleeds for more than 20 minutes.
Several drugs can lead to prolonged bleeding time in patients who took them shortly before the test. This may include aspirin, non -steroidal anti -inflammatory drugs (NSAIDs) and antiHistaminika. The patient should report to the doctor any medication on which he is before the test, including over -the -counter medicines.
thrombocytopenia concerns an abnormally low number of plates, leading to a reduction in body clotting. The condition may result from various causes, such as medicines that can affect the production of plates or primary diseases that lead either to destruction or reduced plate production. Plates of patients who have von Willebrand disease have endangered the coagulation capacity due to the lack of von Will factor factor, protein necessary for the plate's adhesion process. The reluctance of von Willrabrand is most often inherited, but can be obtained as an offshoot of other primary conditions in Rarer cases.
