Answer

Once vital sign abnormalities are corrected, initiate maintenance fluid therapy plus additional fluid to make up for any continued losses. Daily requirements for maintenance fluids can be approximated as follows:

  • If the patient weighs less than 10 kg, give 100 mL/kg/d

  • If the patient weighs less than 20 kg, give 1000 mL/d plus 50 mL/kg/d for each kilogram between 10 and 20 kg

  • If the patient weighs more than 20 kg, give 1500 mL/d, plus 20 mL/kg/d for each kilogram over 20 kg

  • Divide the total by 24 to obtain the hourly rate
