What Are Needle Gauges and Why Are They Important?
Needle gauge refers to the diameter of the needle. It is inversely related to the size; a higher gauge number means a smaller diameter. Common gauges in nursing range from 18 to 30. The gauge is crucial because:
- Smaller Gauges (18-21): Used for thicker medications and blood transfusions. - Medium Gauges (22-25): Suitable for a wide range of intramuscular and subcutaneous injections. - Higher Gauges (26-30): Ideal for insulin injections and pediatric patients.
