Venesection
Venesection, also known as phlebotomy, is a medical procedure that involves the drawing of blood from a patient's vein. This procedure is often used for diagnostic purposes, but it can also be used as a treatment for certain conditions, such as polycythemia and hemochromatosis.
History[edit | edit source]
The practice of venesection dates back to ancient times. The Ancient Egyptians and Ancient Greeks both used venesection as a form of treatment for various ailments. The procedure was often performed by a barber surgeon, who would use a special tool called a fleam to make a small incision in the patient's vein.
Procedure[edit | edit source]
During a venesection, the patient's arm is first cleaned with an antiseptic to prevent infection. A tourniquet is then applied to the upper arm to increase the pressure in the veins and make them easier to see. The healthcare provider then inserts a needle into a vein, usually in the crook of the elbow, and collects the blood in a vial or syringe.
Uses[edit | edit source]
Venesection is most commonly used as a diagnostic tool. By analyzing the blood, healthcare providers can diagnose a wide range of conditions, from anemia to cancer. However, venesection can also be used as a treatment for conditions that cause an overproduction of blood cells, such as polycythemia and hemochromatosis.
Risks[edit | edit source]
Like any medical procedure, venesection carries some risks. These include bruising at the site of the needle insertion, infection, and in rare cases, fainting or feeling lightheaded.
