Why is IV therapy used?
The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body, because the circulation carries them. Intravenous therapy may be used for fluid replacement (such as correcting dehydration), to correct electrolyte imbalances, to deliver medications, and for blood transfusions.
Prepare the patient for the IV push medication.
- Before administrating the push, assess the peripheral IV insertion site for redness, swelling, increased or decreased temperature, or bleeding.
- Wash your hands, as described in step 1.1, and put on clean gloves.
- Prepare the 0.9% saline flush.
- IV push. An IV “push” or “bolus” is a rapid injection of medication. A syringe is inserted into your catheter to quickly send a one-time dose of drug into your bloodstream.
- · nous bo. · lus. a relatively large volume of fluid or dose of a drug or test substance given intravenously and rapidly to hasten or magnify a response; in radiology, rapid injection of a large dose of contrast medium to increase opacification of blood vessels.
- Other conditions treated with specialty infusion therapies may include cancers, congestive heart failure, Crohn's Disease, hemophilia, immune deficiencies, multiple sclerosis, rheumatoid arthritis, and more.
The most common drugs used among IV users are:
- Crystal methamphetamines.
- Prescription drugs.
- The fastest way to get a drug to the brain is by smoking it. When a drug like tobacco smoke is taken into the lungs, nicotine (the addictive chemical in tobacco) seeps into lung blood where it can quickly travel to the brain.
- There are very few drugs which cannot be injected. Heroin is the best known but all the opioids and opiates can be injected as can the stimulants amphetamines and cocaine and almost any drug which comes in tablet or capsule form. Cannabis is very difficult to inject.

The usual initial dose of furosemide is 40 mg injected slowly intravenously (over 1 to 2 minutes). If a satisfactory response does not occur within 1 hour, the dose may be increased to 80 mg injected slowly intravenously (over 1 to 2 minutes).
- Edema The usual initial dose of furosemide is 20 to 40 mg given as a single dose, injected intramuscularly or intravenously. The intravenous dose should be given slowly (1 to 2 minutes). Ordinarily a prompt diuresis ensues.
- Actually, Solumedrol can be given IV push undiluted (maximum concentration 125 mg/mL) over 1-5 minutes for low dosing (<1.8 mg/kg or <12g mg/dose). Moderate dosing (>2 mg/kg or <250 mg/dose) should be given over 15-30 minutes and high dose (15 mg or >500 mg/dose) over an hour.
- The most recent labeling (ie, revised 1993) for Vistaril® Injection states in the Contraindications section, “Hydroxyzine hydrochloride intramuscular solution is intended only for intramuscular administration and should not, under any circumstances, be injected subcutaneously, intra- arterially, or intravenously.”
