Case 4: Fluid Volume Calculations


Maintenance = [(30 x 6.1) + 70] = 253 ml/day

Replacement of dehydration deficit:

English Calculation
0.07 x 13.5 lb = 0.9 lb of weight loss from dehydration
0.9 lb x 454 ml/lb = 429 ml

OR

Metric Calculation
0.07 X 6.1 X 1000 = 427 ml
Correction of 80% of dehydration deficit in the first 24 hours:
0.80 x 427 ml = 342 ml

Total fluid requirement for dehydration plus daily maintenance for the first 24 hours:

253 ml + 342 ml = 595 ml (approximately 25 ml/hour)
