Purposes Of IV Therapy Flashcards
Butterfly
- not commonly used
- used in small veins and maybe only for one med
Over the needle catheters(quick catch)
- Once puncture is made, the metal needle comes out and stylet stays in place
- Replace every 96 hours
Saline Locks
Have access to patients vein but patient not immobilized by constantly having to be hooked up to IV bag
- change every 96 hours
Peripheral site placement
- arms/hands: Pick most distal area of non-dominant hand
- Infants you may use the head
- DO NOT use on side of vesectomy or restricted side
Central IV catheter
- use a subclavian site in upper chest
- triple lumen
Peripherally Inserted Central Line
- can be left in for months
- may be inserted due to patient having difficult venous access
- inserted in arm and delivers into the superior vena cava
Subcutaneous port
Can stay in place for years
-tuning from port extends into vena canvas
Advantages to peripheral catheters
- easy to insert
- generalist nurse can insert
- easy access to use
Disadvantages of peripheral catheters
- Easily dislodged
- interfere with mobility
- infection risk
Minuses of central catheters
- requires more training to insert
- more systemic risk of infection
- more expensive
Pluses of central catheters
- can deliver large amounts quickly
- can deliver vesicant solutions
- more expensive
Infiltration
There’s a leakage of IV FLUID(non-irritating fluid) that leaks into subcutaneous tissue around the vein
Vesicant
IV solution that you are using(irritating solution)
Extravasation
Leakage of irritating fluid into subcutaneous tissue
Phlebitis
Inflammation of the vein
Thrombophlebitis
Inflammation of the vein, along with a clot developing on the end of the catheter
Occlusion
Complete blockage of the end of the catheter,may be due to complete thrombophlebitis, or displacement of catheter
Progenitor reactions
Fever due to contaminated materials, patient will typically complain of fever, headache, back pain due to kidney complications
Circulatory overload
Happens when patient gets too much fluid in the vascular system
-creates pulmonary edema, elevated BP/HR
Air Embolism
A patient receives an amount of air into blood stream that is large enough to cause significant problems
- takes about 10 mL’s to kill or harm pt.
- causes dysrhythmias or stroke
- turn patient onto left side and put into trendelimberg if this happens
Purposes of IV therapy
Give medications Give fluids Give feedings -restore acid base balance -replace blood volume -maintain or replace fluids and electrolytes
