Chapter 10 Flashcards
how large should the syringe be?
twice the size of the fluid
tips fit snugly into a needle hub. does not lock onto the needle hub.
slip tip
offset the tip from the center of the syringe. places the syringe and needle directly in contact with the skin, reducing the angle of needle penetration and making vessel entry much easier for large syringes.
Eccentric slip tips
twist onto the needle hub for a tight fit. safer to use for injections
luer lock tips
elongated and tapered designed to fit into a tube for infusing or aspirating materials
catheter tips

cystocentesis
a single use infusion or blood collection catheter
butterfly infusion
allows continual access to a vein or artery when frequent injections or blood withdrawals are necessary
multiple use catheters
inserting a small amount of solution containing heparin to prevent the blood from clotting

directly visualize a blood vessel in order to insert a catheter, only to be performed on an anesthetized animal
cut down
