Question

you need to give a dog 2000 mLs of Normosol during the next 24 hours. The dog weighs 11.3 kg and is severely dehydrated and lethargic. You'll be using a 15 drop/ml macrodrop administration set.

1. How many drops per minute should be administered?

2. How many mLs per hour should be administered?

3. What would be the correct fluid loss for a 20 kg determined to be 5 % dehydrated?

Answer 1

1)

For calculation of drop per minute, formula used is

Total volume in ml * Drop factor / Time in minutes.

As, Total volume is 2000 ml, Time is 24hrs, drop factor is 15.

Applying these to the above formula,

we get, 2000 * 15 / 1440

= 30000 / 1440

= 21 drops per minute ( approx.)

2)

Formula used to calculate amount of fluid to be administered is

Fluid = 132 * body weight per 24 hours.

Fluid = 132 * 11.3 / 24

Fluid = 62 ml per hour.

3)

Amount of fluid loss in kg = body weight * percentage of dehydration / 100

= 20 * 5 / 100

= 1 kg.

so, amount of fluid loss in ml is 1000 ml. Because 1 kg is equal to 1000 ml.

I hope by the above information u got u r answer.
