The Different Sizes and Types of Cannulae Like many medical terms the word cannula comes from Latin and it means “little reed.” You may see it spelled canula, which can be confusing sometimes when you are looking for a certain product or size, what can also be confusing is the plural form of the word which is cannulae. The device looks like a tube, and is used to by inserting it into the body to remove fluids from the body. The cannula is used to extend the length of the Trocar needle which makes it easier to reach the targeted vein, it will be more than half as long as the introducer. The process of getting a cannula out of the body permanently is termed decannulation. A doctor is the one that will perform this or dictate that it be done, this will happen when the patient no longer needs help breathing. There are different sizes and types of cannulae, the doctor will be the one to determine which is best for each patient. When used in a medical setting a cannula is usually attached to a Trocar needle so that it can puncture the body easily which will make it easier for the device to reach the correct spot of the body. Cannulae come in eleven different types and each of these come in different sizes. The eleven different types include: Welded Ball End, Vet Point, Bias Grind, Closed Consistent Wall, Bullet Point, Probe Point, Deflected Point, Pencil Point, Trocar, Lancet Point and Razor Edge.

An intravenous cannula is the most common type of cannula used in hospital settings. This type of cannula is used mainly by cardiac surgeons when they need to create a cardiopulmonary bypass. A nasal cannula helps the patient get oxygen, for these the tubes are ran under the nose. A venous cannula is used to get the patient intravenous fluids and medicines and is also used to get blood samples from patients. When a patient is in critical condition a doctor can chose to use a cannula in the artery, this will help with blood pressure and will allow them to get blood as much as they need.

Cannulation has the ability to help many patients in a lot of ways, but this also comes with certain risks and complications. These risks and complications are generally grouped into a couple different categories. The categories are phlebitis, infiltration, embolism, and hematoma. As mentioned before, a cannula can vary in sizes and it is based on the type and what it will be used for. It can be very beneficial, especially when being used in the medical field. Although not as common, cannulae can be used outside the field of medicine. These other fields include bio research, synthetic chemistry and aviation.
