In medicine, venipuncture or venepuncture is the process of obtaining intravenous access for the purpose of venous blood sampling (also called phlebotomy) or intravenous therapy. In healthcare, this procedure is performed by medical laboratory scientists , medical practitioners , some EMTs , paramedics , phlebotomists , dialysis technicians ...
The Seldinger technique, also known as Seldinger wire technique, is a medical procedure to obtain safe access to blood vessels and other hollow organs. It is named after Sven Ivar Seldinger (1921–1998), a Swedish radiologist who introduced the procedure in 1953.
Phlebotomy is the process of making a puncture in a vein, usually in the arm, with a cannula for the purpose of drawing blood. [1] The procedure itself is known as a venipuncture , which is also used for intravenous therapy .
A venipuncture performed using a vacutainer. A venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid from the body for analysis.. Blood flows throughout the body, acting as a medium that provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disp
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible.
Venous cutdown procedures most commonly target the great saphenous vein in the leg because it is superficial, easily accessible, and consistently in the same anatomical location. This procedure is used in certain populations such as critically ill patients or patients in hypovolemic shock or when less invasive methods such as peripheral ...
The butterfly's precise placement facilitates venipuncture of thin, "rolling", fragile, or otherwise poorly accessible veins. The butterfly's shallow-angle insertion design facilitates venipuncture of very superficial veins, e.g. hand, wrist, or scalp veins (hence name "scalp vein" set).
Standard catheter. 1. The catheter itself is composed of (a) a tip for insertion into the vein, (b) wings for manual handling and securing the catheter with adhesives, (c) a valve to allow injection of drugs with a syringe, (d) an end which allows connection to an intravenous infusion line, and capping in between uses.
