Infiltration is the diffusion or accumulation (in a tissue or cells) of foreign substances in amounts excess of the normal. The material collected in those tissues or cells is called infiltrate . Definitions of infiltration
Extravasation is the leakage of intravenously (IV) infused, and potentially damaging, medications into the extravascular tissue around the site of infusion. The leakage can occur through brittle veins in the elderly, through previous venipuncture access, or through direct leakage from wrongly positioned venous access devices.
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein.The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth.
ET absorption of medications is poor, and optimal ET drug dosings are unknown. IO administration is becoming more common in civilian and military pre-hospital emergency medical services (EMS) systems globally. [11] Intraosseous access has roughly the same absorption rate as IV access, and allows for fluid resuscitation.
Infiltration (hydrology), downward movement of water into soil; Infiltration (HVAC), a heating, ventilation, and air conditioning term for air leakage into buildings; Infiltration (medical), the diffusion or accumulation of substances or cells not normal to it or in amounts in excess of the normal
Infusion therapy has a range of medical applications including sedation, anesthesia, post-operative analgesic pain management, chemotherapy, and treatment of infectious diseases Advantages of infusion therapy over other non-site-specific delivery methodologies are primarily efficacy through precision of medication delivery.
Infection, phlebitis, extravasation, infiltration, air embolism, hemorrhage (bleeding) and formation of a hematoma (bruise) may occur. A catheter embolism may occur when a small part of the cannula breaks off and flows into the vascular system. When removing a peripheral IV cannula, the tip should be inspected to ensure it's intact.

The definition of the topical route of administration sometimes states that both the application location and the pharmacodynamic effect thereof is local. [ 3 ] In other cases, topical is defined as applied to a localized area of the body or to the surface of a body part regardless of the location of the effect.
