CANNULAE Meaning and
Definition
-
Cannulae, plural of cannula, refers to thin, flexible tubes or hollow needles that are used for various medical and surgical purposes. These instruments are primarily designed to be inserted into the body to either deliver or extract fluids or gases, or to provide access to body cavities or tissues for diagnostic or therapeutic procedures.
Cannulae come in different shapes and sizes depending on their intended use. They are typically made of materials such as plastic or stainless steel, which are chosen for their biocompatibility and durability. The tubes are smooth and rounded to minimize trauma to surrounding tissues during insertion.
In medical settings, cannulae are commonly used for procedures like venipuncture (insertion into veins for blood sampling or intravenous therapy), tracheotomy (creating an opening in the windpipe for breathing assistance), or laparoscopy (minimally invasive surgery using a thin telescope-like instrument).
Additionally, cannulae may be used for drainage or irrigation purposes, such as in wounds or post-operative care. They can be connected to suction devices or fluid delivery systems to facilitate these processes.
Overall, cannulae are crucial tools in modern medicine, allowing healthcare providers to safely and effectively administer treatments, perform procedures, or monitor patients. Due to their wide range of applications, they are indispensable in various medical specialties including anesthesiology, critical care, surgery, and emergency medicine.
