Nur205 Iv Therapy Notes

Front 1

Benefits of IV therapy

Back 1

Allows more accurate dosing.
Drugs given reaches the bloodstream immediately.

Front 2

Risks fo IV Therapy

Back 2

Risks: bleeding, blood vessel damage, fluid overload, infiltration (infusion of the I.V. solution into surrounding tissues rather than the blood vesel), infection, overdose (because response to IV drugs is more rapid), incompatibility when drugs and I.V. solutions are mixed, and adverse or allergic responses to infused substances.
Patient activity can also be problematic.
I.V. therapy is also more costly.

Front 3

I.V. delivery: central vs. peripheral

Back 3

a low-concentration solution must be is infused through a peripheral vein in the arm or the hand.
A more concentrated solution must be given through a central vein.

Medications or fluids that may be administered centrally include:
-those with a pH less than 5 or greater than 9
- those with osmolarity greater than 500 mOsm/L
- parenteral nutrition formulas containing more than 10% dextrose or more than 50% protein
- continuous vesicant chemotherapy (chemotherapy that is toxic to tissues)

3 Basic Methods for delivering I.V. therapy

Back 4

- continuous infusion
- intermittent infusion
- direct injection

Front 5

Continuous Infusion

Back 5

- helps maintain a constant therapeutic drug level
- also used to provide I.V. flyuid therapy or parenteral nutrition

advantages:
less time is spent mixing solutions and hanging containers than with the intermittent delivery method
- less handling of tubing and access to the patient's I.V. = less chance of infection

disadvantages:
patient may become distressed if the equipment hinders mobility and interferes with other ADL's. Drip rate must also be carefully monitored to ensure that the I.V. fluid and medication don't infuse too rapidly or too slowly.

Front 6

Intermittent Infusion

Back 6

Most common and flexible method of administering I.V. medications.

Drugs are administered over a specified period at varying intervals, thereby maintaining therapeutic blood levels.

You can deliver an intermittent infusion through a primary line (most common method) or secondary line.
