Jugular vein
What is the most common vein used for peripheral IV catheter placement in dogs and cats?
Cephalic vein
Where is the lateral saphenous vein located, and when is it commonly used for IV catheter placement?
In the hind limb; when a cephalic vein is not suitable, such as with forelimb surgery or when a cleaner site is needed.
What are the potential consequences of using an IV catheter that is too large?
It can occlude the vein or cause trauma
What size IV catheter is typically appropriate for most cats?
22g
What is the role of an assistant during IV catheter placement?
To restrain the patient and raise the vein, and to “hold off” the catheter after insertion
How does the assistant help raise the vein during catheter insertion?
By rolling their thumb from medial to lateral
What is the purpose of the “flash-back” observed during catheter insertion?
To indicate that the catheter has entered the vein.
What step should be taken after observing the “flash-back” in the stylet?
Advance the catheter and stylet together a little more, then push off the catheter, holding the stylet
What type of tape is generally preferred for securing an IV catheter?
Elastic tape
What is the purpose of placing a V-shaped piece of tape under the catheter?
To provide extra side-to-side stability.
When should the catheter be flushed to check for patency?
After the initial piece of tape is in place

Cannula
What is a common mistake when advancing the catheter off the stylet after seeing the flash-back?
Advancing the catheter off at the first sign of blood, before ensuring the catheter tip is fully within the vein.
