CVAD Focus Flashcards
what can you give through CVAD
IV fluids, blood products, meds
where does the tip of a CVAD end
in the superior and inferior vena cava
what 3 veins can you put a CVAD
internal jugular, subclavian, femoral/brachial
what is a port and what are they mostly used for
CVAD under the skin mostly used for chemo
what is a fluroscopy
pictures via x ray in real time to see a placement of CVAD
what is the only exception for not checking placement on xray is what
fluroscopy
what are some reasons somone would need CVAD
parental nutrition, getting stuck lots of times, chemo, irritating vesicants, blood products, to monitor central venous pressure, hemodialysis
why would you want to monitor central venous pressure
shows fluid overload
how long is a short catheter
1 -1 1/4
how long is a short gauge
26 (smallets) - 14 (largest)
when should you check a short catheter
per policy but minimum of Q 4 hours
how long is a midline
3-8
where is a midline placed what is it used for
upper arm - used when needed for hydration, and drug therapy up to 6-14 days
where is a PICC placed
basilic (preferred) or cephalic in arm they are LONGG
where is the end of a PICC placed
superior vena cava
what is the greatest risk for PICC
DVT, and infection
what is the gold standard for checking PICC placement
3cg technology uses magnet at then end of catheter
who cannot have 3cg technology
someone who doesn’t have normal sinus rhythm
what is a non tunneled catheter how long are they used for
go right into the vein, placed in subclavin in upper chest or jugular put into superior vena cava or taken up from femoral artery into inferior vena cava – short term because of high infection rate - 2 weeks
what is a tunneled catheter
goes under the skin and a antibiotic cuff is placed to decrease risk of infection so you can use it long term
how long can you access a portocath with the same huber needle
7 days
what do you need to do after inserting a huber needle
get blood return and flush with 10ml
what do you need to do after removing huber needle
lock with heparin lock (per policy) and flush
what are some complications for hemodialysis
CLABSI = central line associated blood stream and vein thrombosis
what is the largest cath and what are the intervetions for that
hemodialysis so you need to change dressing every 48 hours or every treatment or when soiled
what are the common infections for CVAD
staph aureus, yeast and fungi
what could happen when disconnection or opening a CVAD
air embolism
what kind of technique do you need to do when changing a CVAD dressing and when do you change it
sterile Q 7 days (or per policy )
before placement of a cath what do you need to ask your patient
if they have an allergy to chlorhexidine gluconate or latex
what kind of CVAD is used for hemodialysis and why
tunneled so the fistula has time to heal it can take 6 months
