infuusiokanyylistä

An infuusiokanyyli, often referred to simply as a cannula, is a medical device used to administer fluids, medications, or blood products directly into a patient's bloodstream or other body cavities. It typically consists of a hollow, flexible tube made of plastic or silicone, with a sharp beveled introducer needle that is withdrawn once the cannula is in place. The outer end of the cannula is designed to connect to an infusion set, which then attaches to an intravenous bag or pump.

The primary purpose of an infuusiokanyyli is to provide venous access. This allows for continuous or intermittent delivery of necessary substances when oral administration is not feasible, efficient, or desired. They are commonly used in hospitals, clinics, and during emergency medical situations. Different sizes of cannulas, indicated by a gauge number, are available to suit various patient needs and the viscosity of the fluid being infused. Larger gauges are used for faster flow rates, such as in trauma situations or blood transfusions, while smaller gauges are suitable for less urgent infusions or for patients with fragile veins.

The insertion of an infuusiokanyyli is a sterile procedure performed by trained healthcare professionals. Proper technique is crucial to minimize the risk of infection, phlebitis (inflammation of the vein), or other complications. Once inserted, the cannula is usually secured to the skin with tape or a specialized dressing to prevent dislodgement. The duration of use varies depending on the patient's condition and the type of infusion.
