A subclavian catheter is a medical device inserted into a vein located beneath the collarbone. It is used to deliver medications, fluids, or nutrients directly into the bloodstream, making it useful for patients who require long-term intravenous therapy. The catheter can also be used for blood sampling and monitoring. The procedure to place a subclavian catheter is typically performed by a healthcare professional in a sterile environment. It involves using imaging guidance to ensure accurate placement and minimize complications. Proper care and maintenance of the catheter are essential to prevent infections and other potential issues.
