79
Q

When should maintenance fluid rates be lower?

A

-Lower in cats than in dogs
-Lower in patients with cardiovascular and renal disease
-Rate should be reduced if anesthetic procedure lasts more than 1 hour (Ideal to reduce fluid rate by 25% until maintenance rates are reached if the patient remains stable)

80

*Dehydration can be corrected over 24-48 hours

82
Q

Replacement Fluid Calculations

A

Volume (mL) of fluid needed = % dehydration x body weight (kg) x 1000
*Vets typically use the rule of 40-60 mL/kg/day
*Once deficit has been determined: total volume can be divided by number of hours over which the dehydration is to be corrected to obtain a mL/hr rate

83
Q

Shock Fluid Boluses

A

-Given in increments (ex 1/3, 1/2) of the calculated amount over a period of 10-30 minutes
-Should be titrated to effect based on the improvement of clinical signs (decreased HR, improved CRT, mm, etc.)
-Crystalloid solution bolus is repeated as needed to achieve normal heart rate and blood pressure

84
Q

Standard shock rate of crystalloid solutions in cats and dogs

A

Cats: 40-60 mL/kg
Dogs: 80-90 mL/kg

85
Q

Why would a shock patient’s fluids be changed from crystalloid to colloid fluids? What’s the shock rate of colloid fluids?

A

-Used if a patient does not respond to crystalloid fluids
-Standard shock rate is 10-20 mL/kg for dogs and 5-10 mL/kg in cats (also given slower)
