What are IV medications?
What is intravenous medication? Some medications must be given by an intravenous (IV) injection or infusion. This means they’re sent directly into your vein using a needle or tube. In fact, the term “intravenous” means “into the vein.”
How does IV medication work?
Unlike injection, infusion uses a pump or the natural force of gravity to deliver fluids into the body. For this reason they are often referred to as drips. The goal with an IV infusion is to produce a controlled delivery of a substance into the bloodstream over time.
What are three ways of administering IV medications?
Intravenous medications by direct IV route can be given three ways:
- Through a saline lock (short venous access device)
- Through an existing IV line with compatible IV solution.
- Through an existing IV with an incompatible IV solution.
Why is IV medication more effective?
Intravenous (IV) administration avoids the first-pass drug effect resulting in direct entry of drug into the systemic circulation and consequently an immediate drug effect.
Why is saline used in IV?
Doctors use IV saline to replenish lost fluids, flush wounds, deliver medications, and sustain patients through surgery, dialysis, and chemotherapy. Saline IVs have even found a place outside the hospital, as a trendy hangover remedy. “It has high levels of sodium and chloride, levels that are higher than the blood.
What are the 5 most common IV solutions?
Hypertonic Solutions
| Type | IV Solution |
|---|---|
| Hypotonic | 5% Dextrose in Water (D5W) |
| Hypertonic | 3% Sodium Chloride (3% NaCl) |
| Hypertonic | 5% Dextrose and 0.45% Sodium Chloride (D50.45% NaCl) |
| Hypertonic | 5% Dextrose and Lactated Ringer’s (D5LR) D10 |
What are the types of saline?
In medicine, common types of salines include:
- Ringer’s lactate solution.
- Acetated Ringer’s solution.
- Intravenous sugar solutions. 5% dextrose in normal saline (D5NS) 10% dextrose in normal saline (D10NS) 5% dextrose in half-normal saline (D5HNS) 10% dextrose in half-normal saline (D10HNS)
What are the advantages of intravenous drugs?
Advantages of intravenous route of drug administration
- Bioavailability is 100%.
- Drug reaches the stream of blood immediately having full access to the entire body and hence, rapid action is produced rendering this route to be the most efficient in life-threatening situations.
What are the different types of IV?
There are three types of IV fluids:
- Isotonic.
- Hypotonic.
- Hypertonic.
What are the two main types of IV fluids?
There are three types of IV fluids: isotonic, hypotonic, and hypertonic.
- Isotonic Solutions. Isotonic solutions are IV fluids that have a similar concentration of dissolved particles as blood.
- Hypotonic Solutions. Hypotonic solutions have a lower concentration of dissolved solutes than blood.
- Hypertonic Solutions.
