kanülengröße

Kanülengröße refers to the diameter of a hollow needle, commonly used in medical procedures for injections, aspirations, or infusions. It is typically measured using the gauge system, an inverse scale where a higher gauge number indicates a smaller diameter. For example, a 25-gauge needle is much finer than a 16-gauge needle. The choice of kanülengröße depends on several factors, including the viscosity of the fluid being administered or withdrawn, the intended use, and patient comfort.

Smaller gauge needles are generally preferred for subcutaneous or intramuscular injections of less viscous fluids, as they cause less tissue trauma and pain. Larger gauge needles are necessary for drawing blood, administering viscous medications, or during surgical procedures where rapid fluid flow is required. Needle length is another important consideration, determined by the depth of penetration needed to reach the target tissue, such as a vein for intravenous access or the muscle for intramuscular injection. Manufacturers provide charts and guidelines to help healthcare professionals select the appropriate kanülengröße and length for specific medical applications, ensuring both efficacy and patient safety.
