Port (medical)
A Port (pronounced: /pɔːrt/), also known as a Central Venous Catheter or Portacath, is a medical device used to administer medications, fluids, or to draw blood. It is a type of intravenous access that can be used for a long period of time, especially in patients who require frequent or continuous treatments.
Etymology
The term "Port" in this context is derived from the Latin word 'portus', meaning 'gateway' or 'entrance'. This is a fitting description as the device serves as an entrance for medications or fluids into the body.
Usage
A Port is typically used in patients who require long-term intravenous treatments such as chemotherapy, total parenteral nutrition, or long-term antibiotic therapy. It can also be used for drawing blood for tests, thus reducing the need for multiple needle sticks.
Procedure
The Port is surgically implanted under the skin in the upper chest or arm. It consists of a reservoir (the port) and a tube that connects the port to a vein. Once the Port is in place, medications or fluids can be given, and blood can be drawn through a special needle that fits right into the port.
