Definition:
Intravenous therapy Or an IV therapy is directly infuse in the veins.
Uses:
Its is use to;
Correct electrolyte imbalance.
To deliver medication.
For blood transfusion.
Fluid replacement.
Use for chemotherapy.
Types:
There are mainly two types of solution;
- Crystalloids.
- Colloids.
* Both are commonly known as volume expander.
1. Crystalloids:
These are the aqueous solution of mineral salts (Normal saline) or other water soluble molecules.
OR
A substance or solution that can pass easily semi permeable membrane.
Solutions:
Normal Saline (0.9% or 0.45% of NaCl)-(Isotonic).
Lactate Ringer's (Ringer's Lactate).
Ringer's acetate (Hyper-tonic)
Benefits:
Most effective.
Safest.
Most economical.
Plasma vol.expander.
2. Colloids:
Those solutions that contains large insoluble molecules, e.g; Gelatin and blood are colloids.
Importance:
Also known as true solutions.
Capable to passing through semi Permeable membrane.
They are physically opposite to Colloids.
Preserve high colloid osmotic pressure in blood.
These are costly solutions.
