Iniectare

Iniectare is the act of introducing a liquid substance into a living body or organism through a needle and syringe or similar device. In medicine and life sciences, injections are used to deliver vaccines, medications, analgesics, hormones, or research compounds. The term is used across medical, veterinary, and laboratory settings. The term stems from Latin roots referring to placing something within.

Routes and purposes: Injections are delivered by multiple routes, including intramuscular, subcutaneous, intravenous, intradermal, and intrathecal administration. The choice depends on the substance properties, desired speed, and patient factors. Some injections are used for local effects, others for systemic distribution.

Equipment and technique: A sterile syringe and needle appropriate to the route are used. Aseptic technique, correct dosage, and accurate injection site preparation are essential. In some cases medications are reconstituted from powder, requiring shaking and compatibility checks. Safety devices reduce needlestick injuries.

Safety and regulation: Injections carry risks such as infection, bleeding, nerve or vessel injury, allergic reactions, and injection-site reactions. They are normally administered by trained health professionals, though some self-administration is permitted for specific medicines with proper instruction. Storage, labeling, and proper disposal of sharps are regulated.

History: Modern injections developed with the invention of the syringe in the 19th century by inventors such as Charles Pravaz and Alexander Wood, enabling precise dosing and safer administration.
