Medical Subject Headings (MeSH): Injections

An injection is a procedure in which a needle is used to deliver medication or other substances into the body. Injections are commonly used in the healthcare industry to administer medications and vaccines, as well as to perform diagnostic tests.

There are several types of injections that may be used in healthcare, including:

Intramuscular injections: These injections are given into a muscle, typically in the upper arm, thigh, or buttocks. Intramuscular injections are often used to deliver medications that are absorbed more slowly by the body, such as certain types of antibiotics.

Subcutaneous injections: These injections are given just under the skin, typically in the abdominal area, upper arm, or thigh. Subcutaneous injections are often used to deliver medications that are absorbed more slowly by the body, such as certain types of insulin.

Intravenous injections: These injections are given into a vein, typically using a small needle or a thin tube called an intravenous catheter. Intravenous injections are used to deliver medications or fluids directly into the bloodstream.

Intradermal injections: These injections are given into the skin, typically using a small needle. Intradermal injections are used to deliver small amounts of medication or to perform diagnostic tests, such as allergy testing.

Injections are usually administered by healthcare professionals, such as doctors, nurses, and pharmacists. It is important for healthcare providers to follow proper infection control practices when administering injections to minimize the risk of infection.
