injektio

Injektio, or injection, is the act of delivering a liquid substance into the body using a syringe and needle or another delivery device. It is a common method for administering medications, vaccines, anesthesia, contrast agents for imaging, or nutrients when oral administration is not feasible or effective. The procedure is typically performed by trained healthcare professionals, though certain injections are designed for self-administration, such as insulin pens.

Parenteral injections are grouped by route of administration. Intravenous injections deliver directly into a vein for rapid effect. Intramuscular injections place the substance into a muscle, while subcutaneous injections deliver into the fatty tissue beneath the skin for slower absorption. Intradermal injections are given into the dermal layer of the skin and are often used for allergy tests or certain vaccines. Other specialized routes exist, such as intra-articular injections into a joint or intrathecal injections into the spinal canal, depending on medical indications.

Equipment and practice emphasize sterility and dose accuracy. Common devices include disposable syringes with needles of various gauges and lengths, ampoules or vials for drug preparation, and autoinjectors for self-use. Proper technique, aseptic handling, accurate dosing, and patient monitoring are essential. After injection, appropriate disposal of sharps in approved containers and observation for adverse reactions are standard procedures.

Risks associated with injekcio include infection at the injection site, tissue or nerve injury, bleeding, allergic or anaphylactic reactions, and incorrect dosing. Safety protocols and training are crucial to minimize these risks and to ensure the procedure is performed in appropriate settings.
