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.
However, in common English the term has mostly been used to describe the four most well-known routes of injection. A peripheral IV placed on the hand. A medical professional performs an intradermal (ID) injection. The term injection encompasses intravenous (IV), intramuscular (IM), subcutaneous (SC) and intradermal (ID) administration. [35]
Intravenous sodium bicarbonate, also known as sodium hydrogen carbonate, is a medication primarily used to treat severe metabolic acidosis. [2] For this purpose it is generally only used when the pH is less than 7.1 and when the underlying cause is either diarrhea , vomiting , or the kidneys . [ 3 ]
Intravenous injections, abbreviated as IV, involve inserting a needle into a vein, allowing a substance to be delivered directly into the bloodstream. [4] An intravenous injection provides the quickest onset of the desired effects because the substance immediately enters the blood, and is quickly circulated to the rest of the body. [5]
Venous access is any method used to access the bloodstream through the veins, either to administer intravenous therapy (e.g. medication, fluid), parenteral nutrition, to obtain blood for analysis, or to provide an access point for blood-based treatments such as dialysis or apheresis.
For example, sodium bicarbonate can be administered IO during a cardiac arrest when IV access is unavailable. [1] High flow rates are attainable with an IO infusion, up to 125 milliliters per minute. This high rate of flow is achieved using a pressure bag to administer the infusion directly into the bone.
Typically, "infusion therapy" means that a drug is administered intravenously or subcutaneously. The term may pertain where drugs are provided through other non-oral routes of administration, such as intramuscular injection and epidural administration (into the membranes surrounding the spinal cord).
