Understanding Cannulas and Their Uses in Medical Procedures

What is a Cannula?


A cannula is a thin tube that is inserted into the body, usually through the skin, to administer or remove fluids or to monitor certain conditions. Cannulas come in various sizes and designs depending on the intended use and area of insertion. The most common types of cannulas are used for intravenous therapy, dialysis, blood collection, and arterial access during surgery.

Intravenous Cannula Insertion and Use
One of the most common uses of cannulas is for intravenous (IV) therapy. An IV cannula is inserted into a vein, usually in the arm or hand, to deliver fluids, medications, blood products, nutrients, or other treatments directly into the circulatory system. The intravenous cannula allows healthcare providers to administer these substances quickly and efficiently without repeated needle sticks.
