A systemic injection refers to a method where medication is injected and subsequently spreads throughout the body, impacting multiple systems or areas beyond the site of injection. This type of injection is often used in scenarios where a broader therapeutic effect is required, such as in the treatment of systemic infections or when a medication needs to reach various tissues. In contrast, local injections are designed to affect a specific area only, such as a local anesthetic administered for a minor procedure. Intravenous injections deliver substances directly into the bloodstream, which can also create systemic effects, but the term refers specifically to how the injection is administered rather than the impact of the medication. Subcutaneous injections introduce medication into the layer of fat beneath the skin, which can also have localized or systemic effects depending on the medication's formulation and intended use. Understanding these distinctions helps nail technicians recognize the implications of injections in regards to client safety, particularly if skin conditions or allergies are involved in their practice.
