What does extravasation mean?
Extravasation is a term used to describe the process of fluid, cells, or other substances escaping from blood vessels or body cavities into surrounding tissues. This phenomenon can occur due to various reasons such as injury, disease, or medical procedures. In a medical context, extravasation is often associated with complications arising from intravenous therapy, where medications or fluids leak into the tissue instead of being delivered into the bloodstream. The term can also be used more broadly to describe the act of pouring or spreading something out. Understanding extravasation is crucial in medical fields to prevent and manage complications. It requires careful monitoring and prompt intervention to mitigate potential damage.
