This test diagnoses bleeding problems related to the abnormalities of: Platelets functions. Platelets response to vascular injury. Vascular response to injury. Blood vessel elasticity also influences the bleeding time. The ability of the blood vessels to constrict. Bleeding times is the best single screening test for acquired causes like uremia or congenital functional or structural disorder of platelets. Sample ------------- This test is done on the patient while he is in the lab. No preparation is needed. The template (Meilke) method is the most common and considered the most accurate. This template is the modified method of Ivy methods. The template method gives 1 mm deep incisions. A small disposable spring-driven lancet gives a 5 mm long and 1 mm deep incision, giving minimal pain and no scar formation. Ivy and Dukeโs methods were used in old times. Indications For Bleeding Time (BT) ------------------------------------------------------- This test is done to evaluate vascular and platelet factors. Bleeding time gives a better idea about the function of platelets, like the numbers of the platelets. This may be done Preoperatively to rule out the possibility of bleeding, e.g., in patients for tonsillectomy, etc. But this may not be the routine presurgical procedure. This test may be done to evaluate the stability of the patientโs hemostatic mechanism. A bleeding test may be done to detect the presence of various coagulation disorders. This may be advised to monitor the treatment of active hemorrhage in patients with prolonged bleeding time due to uremia, von Willebrand disease, severe anemia, and congenital platelets functional abnormalities. Advantages Of Bleeding Time ------------------------------------------------ This test is used to differentiate Von Willebrandโs disease from mild hemophilia. This test is useful as a part of the workup for coagulation disorders in patients with H/O excessive bleeding during dental extraction, tonsillectomy, circumcision, and childbirth, even with normal platelets count. The bleeding time (BT) is used to find any abnormality of the platelets, either number or function. The Disadvantages Of Bleeding Time ------------------------------------------------------------ This test is unable to predict excessive surgical bleeding. Bleeding time is a crude and not a good screening test for bleeding during surgery. The bleeding test will neither predict the likelihood of bleeding nor the likelihood of not bleeding. Bleeding time prick is 9 mm long and 1 mm deep, which may give rise to scar formation. This test is not recommended to predict bleeding in myeloproliferative disorders and neonates receiving nonsteroidal anti-inflammatory drugs. Prolonged bleeding time may not necessarily lead to prolonged bleeding. #bleedingtime #physiologypracticals #physiology #physiologylectures #physiologyvideos #physiologyanimations #usmle #usmlestep1 #usmlevideos #nationalexittest #neetpg #usmlepreparation #mbbs #mbbslectures #nationalexitexam #fmge |
