VADs and Blood Admin Flashcards
What types of catheters are best for administering large volumes of fluid, PN, and other med ?
central vascular access devices (CVADs)
- long term use (chemo, PN)
What is a peripherally inserted central catheter (PICC) used for ?
peripherally inserted central catheter
- long term use (chemo, PN)
What is a peripheral catheter ?
for short term use
- after surgery or a procedure
How do you select a peripheral site ?
- avoid starting IV site on extremity with dialysis graft
- use distal veins prior to distal proximal veins
- use non dominant arm
- need order to use a site that isn’t the upper extremities
- do not select sites on mastectomy side, dialysis, paralyzed
- caution with hard veins, valves, skin bruising or other abnormalities, do not go below previous IV sites
What is phlebitis ?
inflammation of the lining of the vein
- red, painful, streak up vein, possible cord formation (hardening of vein)
What is the difference with infiltration or extravasation ?
- infiltration: leakage of a med that doesn’t irritate the skin
- extravasation: leakage of a med that irritates the skin
What are symptoms of infiltration or extravasation ?
cool, pallor to skin, could be painful, swollen
If infiltration is severe, what can you do to resolve it ?
apply a compress and elevate the affected limb
- aspirate fluid before removing catheter
- warm or cold compress depends on the facility
What is air embolism ?
obstruction caused by air entering the vein
What are symptoms of air embolism ?
- difficulty breathing
- wheezing
- cough
- decreased BP
- increased HR
- chest pain
What can air embolism lead to ?
shock, brain injury, MI, and death
What can do you to prevent air embolism ?
- prime all tubing carefully, check tubing, and IV sets for bubbles
- change bags before they run dry
- stop infusion, position pt with head down on their left side
How do you prevent infections at IV sites ?
- limit disconnecting tube
- teach pt to not handle IV site
- watch pt with SAGE/CHG bath daily
- use catheter stabilization device or tape IV site securely
What is the purpose of whole blood administrations ?
replacement in severe traumatic injuries
What is the purpose of packed RBC blood product ?
- sickle cell disease
- cancer
- anemia
- surgery
- blood loss
- trauma
