Venesection
Venesection (pronounced: /ˌviːnɪˈsɛkʃən/), also known as Phlebotomy or Bloodletting, is a medical procedure that involves the drawing of blood from a patient's vein. The term "venesection" is derived from the Latin words "vena" meaning "vein" and "sectio" meaning "cutting".
History
Venesection has been practiced since ancient times and was a common medical treatment in the Middle Ages. The procedure was often performed by a barber-surgeon, who would use a lancet to cut into a vein and allow blood to flow out.
Procedure
In modern medicine, venesection is typically performed by a phlebotomist or a nurse. The procedure involves inserting a needle into a vein, usually in the arm, and drawing blood into a syringe or vial. The blood can then be tested in a laboratory for various diseases or conditions.
Uses
Venesection is used in the diagnosis and treatment of a variety of medical conditions. It is commonly used to collect blood samples for laboratory testing. In some cases, venesection is used as a treatment for conditions such as polycythemia, a disorder characterized by an overproduction of red blood cells, and hemochromatosis, a condition that causes the body to absorb too much iron from the diet.
Risks
Like any medical procedure, venesection carries some risks. These can include bruising at the site of the needle insertion, infection, and in rare cases, fainting or feeling lightheaded.
