Peripheral Venous Catheters (PIVCs) types - Answer Short PIVCs

Midline catheter
Short PIVCs - Answer 1. Inserted into superficial veins
2. Duration of therapy = <4 days
3. Length of catheter = <3"

5. Not appropriate for vesicants, irritants, are parenteral nutrition
Long PIVCs - Answer 1. Inserted in either superficial or deep peripheral veins
2. Can be considered when:
- short PIVC is not long enough to cannulate available vein
- difficulty palpating or visualizing vessels with naked eye
Midline Catheter (MC) - Answer 1. Duration of therapy = 5-14 days
2. Can be inserted thru basilic, cephalic, or brachial veins and terminate at or before axillary lvl
3. Not considered a central line -> no continuous vesicants/extreme pH or osmolarity/parenteral
