Ch 16: Parenteral Access Devices Flashcards
What are CVC most commonly made of?
polyurethane or silicone
If duration of therapy is considered to be < 1 week of nonirritant, nonvesicant, and non-hyperosmolar infusion therapy, what type of line should be considered?
Peripheral line
How often should peripheral line be changed?
CDC recommends monitoring of peripheral access with IV line removed no more frequently than every 72-96 hours unless clinically indicated
Thrombotic occlusions are usually treatment with what?
Thrombolytics
In what situations should a PICC line be placed with caution?
In patient with CKD with need to preserve peripheral/central veins for possible AV graft creation
How are catheter sizes expressed?
as diameter, French size, and gauge. Diameter can refer to internal or external diameter and is measured in millimeters
What type of line is suited for peripheral compatible solutions where treatment is considered for 2-6 weeks
Midline catheters
Why would a port be placed?
Mediports are subcutaneous access ports implanted under the skin. They provide a way for long-term venous access without multiple needle pricks. They are used for treatments such as chemotherapy, intravenous medication and blood transfusions.
What is the measure of French size?
outer diameter (1 mm= 3 French)
What is a central line bundle?
5 components recommended to reduce risk of CRBSI
o Hand hygiene o Maximal barrier precautions o CHG skin antisepsis o Optimal catheter site selection o Daily review of line necessity with prompt removal of unnecessary lines
When would of use of percutaneous nontunneled catheter be appropriate?
In acute care settings for therapies of short duration; dwell time is limited to 5-7 days
What is a PICC line classified as?
Non tunneled CVAD
What are the advantages of a tunneled CVC?
decreases risk of catheter infection by separating the exit and venipuncture sites; in general, is correlated with lower rates of infection , save and effective in long term therapies ranging from months to years, ease of self-care by patient, placement on chest wall so covered by clothing, decreased risk of dislodgement, ability to repair the external lumen in even of catheter breakage
What is the preferred vessel for central access and infusion of PN?
The Superior Vena Cava (SVC) has estimated blood flow of 2000 mL/minute making in the preferred vessel
How long can a PICC line dwell?
Appropriate for infusion of irritants and vesicants (such as PN) and chemo, for any length of duration with PIC lines dwelling for months to years
