An IV cannula, also known as an intravenous cannula, is a small, flexible tube inserted into a vein, usually in the hand or arm. It allows for the administration of fluids, medications, or blood products directly into the bloodstream.
The process of inserting an IV cannula is called intravenous cannulation. It is a common medical procedure performed by healthcare professionals, such as nurses and doctors.
Here are some additional details about IV cannulas:
- Purpose: IV cannulas are used for various medical purposes, including:
- Fluid replacement: Providing hydration to patients who are dehydrated.
- Medication delivery: Administering drugs that need to be delivered quickly and directly into the bloodstream.
- Blood transfusions: Delivering blood or blood products to patients who need them.
- Blood draws: Taking blood samples for laboratory testing.
- Types: IV cannulas come in different sizes and types, with the gauge (diameter) of the cannula being an important factor in determining its suitability for specific uses.
- Placement: IV cannulas are typically placed in peripheral veins, such as those in the hand or arm. In some cases, they may be placed in central veins, such as those in the neck or chest.
- Complications: While generally safe, IV cannulation can lead to complications, such as:
- Pain and discomfort: The insertion process can cause pain and discomfort.
- Bleeding: Some bleeding may occur at the insertion site.
- Infection: Infection is a potential risk, especially if proper hygiene practices are not followed.
- Extravasation: This refers to the leaking of fluids or medications into surrounding tissues, which can cause damage.
