Equine IV Catheterization and Fluid Therapy Flashcards
what kind of iv catheter do you chose prevent thromboembolism
least reactive
shortest
smallest diameter
iv catheter length range
2-3” up to 5-6”
diameter range from IV catheters
10-14 gauge
reactivity for polypropylene catheters
stiffness: high
reactivity: most
duration: <24 hours
reactivity for teflon, polyurethane catheters
stiffness: medium
reactivity: medium
duration: 7 days
reactivity for silicone catheters
stiffness: least
reactivity: low
duration: 4 weeks
preferred IV catheter site for equine
jugular - either side
Inflammation of Vein caused by blood clot
thrombophletbitis
two area where thrombophlebitis can begin
catheter itself
damaged vein
four steps to treatment of thrombophlebitis
- remove catheter - discontinue use of vein
- hot pack
- DMSO
- antibiotic ointment
what DMSO
Topical chemical solvent that is sometimes used to help reduce inflammation and pain
clinically normal dehydration rate
5%
mild skin turgor dehydration rate
6-7%
turgor, tacky MM dehydration rate
8-9%
turgor, tack MM, sunken eye dehydration rate
10-11%
shock, collapse, death dehydration rate
12%+
formula for total fluid rate
TFR = MR + RR + OLR
maintenance fluids needed daily for large animals
60 ml/kg/24 hours
how do you figure maintenance rate
(weight in kg * 60 ml) / 24 hours = ml/hr
how do you figure rehydration rate
(% dehydration x kg) x 1000 = ml of fluid needed
ml of fluid needed / time (replacement over how much time) = ml/hr
how do you calculate ongoing fluid loss
2x the “estimated” rate that fluids are being lost
what is fluid rate always reduced down to
ml/hr
two routes for fluid therapy admin in equine
GI - if functional
IV
In 🐎 🐴
max fluid therapy given by GI
1 gallon every 30 - 60 minutes
which fluid therapy route is not sufficient for shock
GI
designed to deliver fluids from bottles by sliding the “_____” portion over the mouth of the bottle and inserting the tip into a catheter in a vein
