The Holliday-Segar Method
In the Holliday-Segar Method, fluid and electrolyte requirements are empirically based on the caloric needs of the average hospital patient. This caloric expenditure is approximated based on body weight using the following table:
Relation of Body Weight to Caloric Expenditure For each kilogram in this range Daily caloric cost per kilogram 1-10 kg 100 kcal/kg/day 11-20 kg 50 kcal/kg/day >20 kg 20 kcal/kg/day
For every 100 kcal expended, a certain amount of fluid is lost either through "insensible water loss" or through renal function; a small amount is generated thro
