Safety Needle Injection Type

Needle selection criteria

The needle provides the main function of injecting drugs. Injections are a growing medical application. In 2016, US hospitals spent 25.8 billion U.S. dollars on injecting drugs. "In the emergency patient care environment, injectable drugs are ubiquitous. Compared with other routes of administration, injectable drugs have many advantages, including precise and adjustable dosage, predictable bioavailability, and rapid onset of action." The needle that best suits your needs starts with the type of injection. There are three types of injections, and the parts on the body that can be used for these injections. After determining the injection type, the next step is to determine the needle size, and then the needle length.

Needle injection type

There are three typical injection sites-intradermal, subcutaneous and intramuscular. The deeper the injection site, the longer the length of the needle, and the more direct or perpendicular the needle path is to the delivery tissue. However, the shorter the needle length, the less pain or bruising experienced by the patient receiving the injection. "In general, procedural pain, especially intramuscular (IM) injection pain, is one of the most distressing and painful health care experiences for children."
