Peripheral arterial catheterization is a medical procedure that involves the insertion of a small, flexible plastic tube, called a catheter, into a peripheral artery in order to monitor blood pressure and collect blood samples for analysis. It is often performed in critical care units or during surgical procedures, where continuous monitoring of blood pressure and arterial blood gases is necessary.
During the procedure, a healthcare provider will locate a suitable peripheral artery, such as the radial artery in the wrist or the femoral artery in the groin, and prepare the area by cleaning and sterilizing it. The catheter is then carefully inserted into the artery and advanced to the desired location. Once in place, it is secured using a sterile dressing or sutures.
Peripheral arterial catheterization allows for frequent and continuous monitoring of blood pressure, which is especially important for patients with unstable or critically ill conditions, as it helps healthcare providers assess the effectiveness of interventions and make timely adjustments to treatment plans. Additionally, blood samples can be easily withdrawn through the catheter without the need for repeated needle sticks, reducing patient discomfort and minimizing the risk of complications associated with frequent blood draws.
Although peripheral arterial catheterization is generally considered a safe procedure, it is not without potential risks, such as bleeding, infection, and damage to the artery or surrounding tissues. Therefore, it is crucial that the procedure is performed by skilled healthcare professionals under strict aseptic technique and close monitoring.
