Peripheral arterial catheterization refers to a medical procedure that involves the insertion of a thin, flexible tube called a catheter into a peripheral artery, usually in the arm or leg. The purpose of this procedure is to directly access and monitor blood pressure and blood oxygen levels in the arteries to diagnose and manage various medical conditions.
During a peripheral arterial catheterization, a healthcare professional carefully inserts the catheter into the arterial blood vessel using a small incision or through the use of an artery puncture technique. The catheter is carefully positioned within the artery, allowing for accurate monitoring of blood pressure and oxygen saturation levels. This procedure is often performed in a hospital setting, typically in an operating room or special catheterization lab.
Peripheral arterial catheterizations are commonly utilized in situations where continuous and accurate blood pressure monitoring is necessary, such as during major surgeries, critically ill patients, or in intensive care units. Additionally, this procedure enables the collection of arterial blood samples for laboratory analysis, which can provide valuable information about the patient's overall health status.
While peripheral arterial catheterizations are generally considered safe, there are associated risks, including infection, bleeding, blood vessel damage, or blood clots at the site of insertion. Therefore, healthcare providers closely monitor patients during and after the procedure to minimize potential complications and ensure the safe and effective use of the catheter.
