Lecture 4: IV administration Flashcards
Why can’t all IV medications be given rapidly?
Infusion-related reactions and complications may result
What should be considered to determine which type of IV administration to be used? (Push/Intermittent/Continuous)
medication
concentration
total volume
Compounding IV push/IV intermittent
Reconstitution/further dilution
Stock solution
Sometimes no compounding is necessary
- straight draw out of vial, no dilution or manipulation needed
IV administration
can be central or peripheral
Vascular access device (VAD)
term that encompasses both peripheral and central access
Peripheral catheter
small IV catheter placed into small peripheral vein for short-term use
Central venous catheter (CVC)
IV catheter terminating at superior vena cava
Catheters used for medication, fluids, TPN, and blood draws
Peripheral catheter
Central venous catheter
Types of central venous catheters
Peripherally inserted central catheter (PICC)
Long term central catheter (LTCC)
Peripherally inserted central catheter (PICC)
Inserted at peripheral site
travels into superior vena cava
Long term central catheter (LTCC)
mediport
tunneled CVC
Benefits of peripheral catheter
Convenient easy to use
minimal ADR
Risks of peripheral catheters
Limitations of what can be infused
short term use hrs-days
Benefits of central catheters
Fever limitations on what can be infused
Long term use wks/mon/yrs
Cons of central catheters
Placement requires trained personnel, may require sedation
Complications
- infection of central line
- line fracture/break
Phlebitis
Inflammation of the vein
How does phlebitis occur?
at placement of vascular access device (VAD) and in the direction of blood flow
Phlebitis is characterized by
Tenderness
Redness
Puffiness
Increased temperature
IV infiltration
Fluid/medication infuses into the tissues surrounding the venipuncture site
IV infiltration occurs when
Tip of the catheter slips out of the vein
Catheter passes through the wall of the vein
Blood vessel wall allows part of the fluid/medication to infuse into the surrounding tissue
Signs and symptoms of IV inflitration
Redness around the site
Swelling, puffy or hard skin
Pain
Blanching
IV not working
Cool skin temperature around the IV site or the scalp, hand, arm, leg or foot near the site
Vesicant
drug that results in tissue necrosis when accidentally infused into the tissues surrounding a vein
Examples of vesicants
Neurotransmitters (NE,DA, EPI)
Chemotherapies
calcium salts
Extravasation
Infiltration of a vesicant into the surrounding tissue
