A peripheral catheter is a small, flexible tube inserted into a vein, usually in the arm or hand. It allows healthcare providers to deliver medications, fluids, or blood products directly into the bloodstream. This type of catheter is commonly used in hospitals and clinics for patients who need ongoing treatment or hydration. The insertion of a peripheral catheter is a quick and relatively painless procedure. Once in place, it can remain for several days, making it easier for nurses to administer treatments without repeatedly poking the patient. Proper care and maintenance are essential to prevent infections and ensure the catheter functions effectively.
