Peripheral venous catheter

Peripheral venous catheter (PVC), also known as a peripheral venous line or peripheral venous access catheter, is a catheter (tube) that is inserted into a vein in the peripheral vascular system to administer medication or fluids.

Overview

The peripheral venous catheter is the most commonly used vascular access in medicine. It is given to most emergency department and surgical patients, and before some radiology procedures. The catheter is inserted into a small peripheral vein, such as the veins in the hand or forearm, and then connected to a bag containing the fluids or medication.

Procedure

The procedure to insert a peripheral venous catheter involves several steps. First, the skin is cleaned with an antiseptic to prevent infection. Then, a tourniquet is applied to the upper arm to increase the pressure in the veins in the lower arm, making them easier to find. The catheter is then inserted into the vein and the tourniquet is removed. The catheter is then connected to a bag containing the fluids or medication.

Complications

Complications of peripheral venous catheter use can include phlebitis, infection, and thrombosis. Phlebitis, or inflammation of the vein, can occur from the catheter irritating the vein. Infection can occur if bacteria enter the body through the catheter. Thrombosis, or a blood clot, can form if the blood flow around the catheter is slow.
