{{Adult top}} [[Intravenous fluid therapy (peds)]] or [[critical care quick reference]] for bolus doses by weight.''
==Background==
{{IVF composition}}
{{Total body water}}

==Acute Repletion (Bolus)==
*Typically 20-mL/kg aliquots of isotonic (e.g., NS or LR) fluid

==Maintenance Fluids==
*Insensible losses = 300-400 cc/m2/d
*Adult Standard: D5 0.45%NS at 75-125 mL/hr + 20meq/L of KCl
*Deficit: % dehydration x baseline weight
*Daily volume needed = maintenance + deficit - fluid already given (i.e. boluses)
**Hourly rate  daily volume/24 hr
***(or correct 1/2 of deficit in first 8 hr, remainder in next 16)

==Electrolytes==
*Maintenance Na = 3 mEq/kg/d; K = 2 mEq/kg/d
*Deficit = [desired - measured mEq/L] x fD x wt (kg)
*fD (distribution factor) Na = 0.6, K = 0.6, Cl = 0.2-0.3, HCO3 = 0.5
*(Maintenance + deficit)/daily volume = concentration of electrolyte in fluid to be given
*4mL/kg of H2O lost, ups Na by 1meq
