 In general, adults need 35 mL water per kg body weight, children need 70 -100 mL/kg, and infants need 150 mL/kg.
Fluid needs are increased with excessive sweating, vomiting, diarrhea, or tube drainage.
Fluids are restricted in certain disease states such as renal failure and congestive heart failure |
Example Fluid Needs Calculation
-
| 70 kg man:
35 mL/kg x 70 kg = 2450 mL/d |
-
-
| 30 kg child:
70 to 100 mL/kg x 30 kg = 2100 to 3000 mL/d |
-
-
-
| 5 kg infant:
150 mL/kg x 5 kg = 750 mL/d |
