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.
In medicine, infusion therapy deals with all aspects of fluid and medication infusion, via intravenous or subcutaneous application. A special infusion pump can be used for this purpose. [1] A fenestrated catheter is frequently inserted into the localized area to be treated.
The user interface of pumps usually requests details on the type of infusion from the technician or nurse that sets them up: . Continuous infusion usually consists of small pulses of infusion, usually between 500 nanoliters and 10 milliliters, depending on the pump's design, with the rate of these pulses depending on the programmed infusion speed.
A comparison of intravenous (IV), intramuscular (IM), and intraosseous (IO) routes of administration concluded that the intraosseous (IO) route is the preferred method versus intramuscular (IM) and comparable to intravenous (IV) administration in delivering pediatric anaesthetic drugs. [17]
The term injection encompasses intravenous (IV), intramuscular (IM), subcutaneous (SC) and intradermal (ID) administration. [ 35 ] Parenteral administration generally acts more rapidly than topical or enteral administration, with onset of action often occurring in 15–30 seconds for IV, 10–20 minutes for IM and 15–30 minutes for SC.

A patient-controlled analgesia infusion pump, configured for intravenous administration of morphine for postoperative analgesia. In a hospital setting, an intravenous PCA (IV PCA) refers to an electronically controlled infusion pump that delivers an amount of analgesic when the patient presses a button. [4]
Typically, it is limited to 1 mL per minute, although it is possible to increase this by using two sites simultaneously. The chief advantages of subcutaneous infusion over intravenous infusion is that it is cheap and can be administered by non-medical personnel with minimal supervision. It is therefore particularly suitable for home care.
V-Set: Multiple line IV injection site whereby several lines can be used at the same time for administering drugs to the patient.. In intravenous therapy a Y-Set, T-Set and V-Sets are Y-, T- and V-shaped three-way connector sets made of connecting plastic tubes used for delivering intravenous drugs into the body from multiple fluid sources.
