infusion

1. the steeping of a substance in water to obtain its soluble principles.

2. the product obtained by this process, usually leaves, young stems, or petals to produce a tea for oral administration. See also decoction.

3. the slow therapeutic introduction of fluid other than blood into a vein. See also intravenous infusion.

note: An infusion flows in by gravity, an injection is forced in by a syringe, an instillation is dropped in, an insufflation is blown in, and an infection slips in unnoticed.

constant-rate infusion

the continuous intravenous administration of medication usually through an electronic delivery device, in order to maintain constant blood levels. Most suitable for use with rapid onset of action and short half-life.

intramammary infusion

May be in liquid or thin paste form and usually prepackaged in tubes for the treatment of individual quarters. Contain antibiotics and adjuvants in a slow or fast-release base depending on objective, e.g. dry period or lactation period treatment. May contain dye to warn that milk may contain antibiotics. Specially prepared watery infusions of escharotic agents, e.g. silver nitrate, copper sulfate, may be used to dry off permanently a quarter that is chronically affected.
