1/3mm

1 French= _____mm

second | Tom Cat

A Slippery Sam catheter is used _________ after _______ catheter

cephalic vein | ventral

A penrose drain works great with a _________, recommend placement via a ________ incision

- a catheter containing only a needle attached to two "wings", and an extension tube - wings are NOT for suturing into place! - Only recommended for short term use

Butterfly catheter

blood draws and injections

Butterfly catheters can be used for

wiggly patients and cats

Butterfly needles are mainly used on

- flexible rubber catheter with an inflateable cuff on one end to hold it in place, and two ports on the other end - two ports (one to the cath. and one to the cuff) - long term use - inflate cuff with warm STERILE H2O or SALINE - Individually wrapped and sterile

Foley Catheter

Intravenous Catheter

IVC

- tubing used to connect the fluid bags/bottles to the T-port - contain a drip chamber and a fast ball that controls the amount of fluid running through the line - individually wrapped in sterile packages

Intravenous drip sets

- creates negative pressure via bulb - can be left in for 3-5 days

Jackson Pratt drain

- does NOT have a needle in the drip chamber - large drops of fluid - 10gtt/ml | 15gtt/ml | 20gtt/ml

Macro-drip Set

- contains needle (stylet) in the drip chamber - smaller drops of fluid - 60gtts/ml

Micro-drip Set

- use of a butterfly catheter - the wound is sutured closed to create an airtight space - the "wings" are sutured to the ot and use of a blood tube attached to the needle will create negative pressure and collection of fluid - red top tube - need to change tube every time= looses the negative space

Modified Jackson Pratt Drain

18ga= cows, horses, or SQ fluids 20ga= cows, horses, very large dogs 22ga= cats/dogs 25ga= neonates

Needle IM/SQ Injections

20ga= cows, horse, large dogs 22ga= cats, dogs 25ga= neonates

Needle IV Injections

- diameters are measured in gauges - the length is measures in inches

Needles

- the catheter covers the outside of the needle (stylet). - once placed in a vein the stylet is removed and the catheter remains

Over the needle Catheter

Cephalic vein

Over the needle catheters are commonly placed in the ________

- used for draining wounds, abscesses, and used as a tourniquet - available in various widths - individually wrapped in sterile package

Penrose Drain

- Rigid plastic catheter - not recommended as an indwelling catheter - packaged in a sterile container with many other catheters (once package is opened= no longer sterile) - Can individually wrap and sterilize tubes for future use

Polypropylene Catheter

dogs and blockages

Polypropylene catheters are used for __________

- short, soft catheter with "holes" around the hub for suturing in place - long term catheterization in male feline patients

Slippery Sam catheter

- most comon sizes are 1, 3, 6, 12, 20, 35, and 60ml (cc) - another name for a 1ml syringe is a "tuberculin" - syringes are also avilable with different types of tips

Syringes

- used between the catheter and the drip/extension set - has two ports (one attached to catheter for injections, and one port for connecting fluids) - may have Luer-Lock - always has a clamp

wings | pinching

The butterfly catheters _______ are used as handles by ________ the wings

True

The larger the number in Fr, the larger the diameter

- has a long flexable tube (catheter) which is threaded through the needle - Once catheter is inside the vein, the needle is removed and placed in a protective cover. - Multi-step process and training is needed
