Fluid loss calculation & intake protocols

Question 1

Fluid loss calculation & intake protocols

Answer 1

-Holliday-Segar Method: maintenance fluid daily :
■ Body weight between 1-10 kg: 100 mL/kg
■ BW between 11-20 kg: 1000 mL + 50 mL/kg for each kg between 11-
20
■ BW more than 20 kg: 1500 mL + 20 mL/kg for each kg over 20 kg
■ So maintenance for a 22kg patient: it’s 1500 + 40 = 1540 mL/day

-Fluid bolus: 10-20 mL/kg. Must be isotonic solution. Can give bolus rapidly up
to 3 times in severe cases.

-**During IV fluid therapy for dehydration: the first half of total daily volume is
given in the first 8 hours, the second half is given over 16 hours.

-Fever: extra 10% fluid needed for each degree celsius above normal

-Give excess fluid in tumor lysis syndrome, poisonings

• Restrict fluid to prevent pulmonary edema in case of pneumonia (80%
  normal), SIADH, cardiac malformations, renal failure with oliguria
