Platelets should be transfused at a rate of 10 milliliters per minute for approximately 30 minutes, explains the Department of Pathology at the University of Michigan Health System. Platelets are typically transfused in cases of severe bleeding in people with a low platelet count and should be transfused quickly to receive their full benefit.Know More
It is always important to reassess bleeding and take a platelet count after a transfusion. The normal platelet count is between 150,000 and 400,000 per cubic millimeter. The American Cancer Society explains that the risk of dangerous bleeding becomes elevated when the count drops below 20,000 per cubic millimeter.
Platelets originate in the bone marrow from cells called megakaryocytes. They are fragmented cells in the blood that become activated when bleeding occurs. A decrease in platelets can occur because of decreased production in the bone marrow, increased destruction in the bloodstream or an increased destruction by the liver or spleen, according to MedlinePlus.
Platelet counts can also be increased in a condition called thrombocytosis, notes MedlinePlus. This can be directly due to primary thrombocytosis or may occur secondary to anemia, infection, cancer, medication side effects, polycythemia vera or splenectomy. People with elevated platelet counts have an increased risk of forming blood clots, which leads to serious medical problems.Learn more about Medical Ranges & Levels
According to the Platelet Disorder Support Association, a change in diet can help build up blood platelets. An organic diet rich in nutrients can have a beneficial effect on someone's platelet count.Full Answer >
Symptoms of low platelet count, or thrombocytopenia, include blood in urine or stools, excessive bruising, prolonged bleeding from cuts and petechiae, which is a rash of small, reddish-purple spots, according to Mayo Clinic. Platelets perform a vital role by clumping in the blood vessels to stop blood loss.Full Answer >
A person can have low blood platelet count, or thrombocytopenia, because of genetic history or medical conditions, according to Mayo Clinic. Drugs such as those used in chemotherapy can also cause a low platelet count.Full Answer >
A patient with abnormally low blood platelet count displays a condition called thrombocytopenia, according to Mayo Clinic. Thrombocytopenia, with symptoms of abnormal bruising or bleeding, can be diagnosed by a blood test or physical exam. A normal blood platelet count ranges from 150,000 to 450,000 platelets per micrometer of circulating blood, but a patient with the disorder has less than 150,000.Full Answer >
