IV (intravenous) catheter

This refers to the placement of a small, flexible, tubular instrument that is passed into a vein (typically in the forelimb) and secured there to provide a port that allows delivery of fluids, nutrition, or blood products directly into the bloodstream. This is often used as a safety measure in pets that will undergo an anesthetic or surgical procedure to support blood pressure by administration of fluids and to allow fast access to the vein in case of emergency. It is also used in sick pets in order to help maintain proper hydration and nutrition when they are unable to take in enough water or food orally due to vomiting or diarrhea.
