Injekcijomis

Injekcijomis refers to the act of administering substances directly into the body using needles or cannulae. In medical practice, injections are a primary method for delivering drugs, vaccines, diagnostic agents, and other therapeutics. The term originates from the Latin word "injectio," meaning "to put in." In Lithuanian, injectioms often appears in medical contexts, especially within clinical documentation and health education.

Types of injections are classified by anatomical route and dosage form. Local injections deliver medications to a specific body site and include intramuscular (IM), subcutaneous (SC), and intraarticular routes. Systemic injections, which affect the entire body, are typically administered either intramuscular or intravenously (IV). While IM and SC injections rely on tissue absorption, IV injections introduce substances directly into the bloodstream, providing immediate bioavailability. Other specialized routes include intradermal, intrathecal, and intraocular, each chosen for particular therapeutic targets.

Clinical uses cover a broad spectrum: vaccines are administered to induce immunity; analgesics and anesthetics provide pain relief; chemotherapeutic agents treat cancer; anticoagulants prevent blood clots. In diagnostic medicine, contrast dyes for imaging studies are injected to enhance visibility of internal structures. Veterinary medicine also relies heavily on injections for disease control in animals.

Safety is paramount; sterility, correct dosage, and appropriate technique mitigate risks. Common side effects are mild local reactions such as pain, redness, or swelling, while severe complications may involve infection, allergic reactions, or accidental intravascular injection. Proper training, adherence to guidelines, and patient monitoring help ensure effective and safe injection practices.

The history of injections dates back to the 19th century, with William Morton’s development of ether anesthesia and advancements in syringe design that facilitated widespread medical use. Modern advances in disposable syringes, autoinjectors, and needle-free jet injectors aim to improve safety, reduce needle-stick injuries, and increase patient comfort.
