What is the primary function of an intravenous (IV) catheter during surgery?

The primary function of an intravenous (IV) catheter during surgery is to deliver medications and fluids directly into the bloodstream. This provides immediate access to the vascular system, allowing for rapid administration of necessary drugs, such as anesthesia, pain management medications, or intravenous fluids to maintain hydration and blood volume.

Using an IV catheter is crucial during surgical procedures for maintaining hemodynamic stability and ensuring that any medications can take effect quickly, which is vital in the dynamic environment of the operating room. This availability of immediate treatment facilitates better intraoperative management and overall patient outcomes.
