Cannula comes from the Latin word which means ‘little reed’. This can also be spelled as canula, so you must not get confused when looking for cannula sizes. Its plural form is cannulae. The device is a kind of tube, which is inserted into the body to remove or get some fluid from the inside.
The tube can envelop the outer surfaces and inner portion of the Trocar needle to help in extending its advancement to the targeted vein by more than half of the length of the introducer. The process of getting any cannula sizes out permanently is called decannulation. Only a doctor can instruct or dictate this is done and likewise if the device is no longer needed in helping the patient breathe.
Different Types dermal cannula
Cannula sizes differ depending on the types of the device. In the field of medicine, cannulae usually have a trocar attachment that helps in puncturing the body to properly place the material in the intended space. These are the 11 types of cannulae that come in different cannula sizes. These include Vet Point, Bullet Point, Deflected Point for Anti-Coring, Welded Ball End, Bias Grind, Closed-End Consistent Wall, Probe Point with blunt end, Trocar, Pencil Point, Razor Edge and Lancet Point.
There are many types of cannulae and cannula sizes that are used in hospitals, but the most common of all are the intravenous cannulae. Most of these are utilized when cardiac surgery needs to be performed by establishing a cardiopulmonary bypass. The nasal cannula is used to administer oxygen by running the plastic tubing beneath the nose. The venous cannula, on the other hand, is used to administer intravenous fluids, medicines and in getting blood samples from patients. The arterial type is placed in the artery when the patient is under critical care, to help in observing blood pressure and to get blood samples as often as needed.
The process of cannulation may be able to help patients in many ways, but there are also certain complications that may arise from this. These complications are grouped into four categories, such as embolism, hematoma, infiltration and phlebitis.
