IV Cannulas Essential Tools for Modern Medical Care

IV cannulas typically consist of a thin, flexible tube made from biocompatible materials such as plastic. At one end, there is a sharp, beveled needle designed for easy insertion into a vein. Once the needle pierces the vein and the cannula is advanced, the needle is withdrawn, leaving the cannula in place for continued access. The hub of the cannula includes features such as wings for stabilization and may be color-coded to indicate the size or gauge of the cannula.

Indications and Uses
IV cannulas serve numerous clinical purposes, including:
Fluid Replacement Administering fluids to patients who are dehydrated, hypovolemic, or unable to tolerate oral fluids.

Medication Administration: Delivering medications directly into the bloodstream for rapid onset and reliable absorption.

Blood Product Transfusion: Facilitating the transfusion of blood components such as red blood cells, platelets, and plasma.

Nutrition Support: Providing essential nutrients and calories intravenously when oral or enteral feeding is not feasible.
