Medical Uses For The 25 Gauge Needle

There are some needle gauges that are very versatile and some that are designed for specific uses. The 25 gauge needle is one of the most versatile gauges out there since it is slightly higher bore than many needles and is a good choice for both subcutaneous injections (SQ) as well as intramuscular injections (IM).

Medical professionals that use the 25 gauge needle will have a variety of different syringes to match with the needle from a small syringe that holds 1cc to much larger 5 or 10 cc syringes. The specific type of injection and the volume of the injection will be the deciding factor in syringe selection.

Needle length is also factor of the type of injection and the site of the injection. The most common lengths used with a 25 gauge needle include the shorter 5/8 inch length, ideal for subcutaneous injections, to the longer 1 to 1¬Ĺ inch needles that are most commonly used for IM injections.

Tips for Selecting Needle Length for IM Injections

With the 25 gauge needle IM injections are done at a ninety degree angle to the surface of the skin. This means that the needle is inserted with a quick thrust perpendicular to the surface of the body. The needle length is selected based on the weight and size of the individual receiving the injection. Babies, infants and toddlers require the shorter needles while women and men, based on their weight, will use the longer needles.

Typical injection sites for IM injections using the 25 gauge needle include the deltoid muscle or the anterolateral thigh. Children and babies the anterolateral thigh is the preferred location.

Tips for SQ Injections with 25 Gauge Needles

Injections under the skin, SQ, are administered at a 45 degree angle to the surface with a slight pinching of the skin to pull up and away from the underlying muscle layers. These are typically administered to the fatty area of the thigh or the outer part of the upper arm. For almost everyone the recommended length of the 25 gauge needle will be 5/8 of an inch.

For medical professionals the choice of a 25 gauge needle makes sense given the practical aspects of this size. When providing multiple injections at the same time, regardless of the needle gauge, always space injection sites as far apart as possible.
