Determine Mr. Hayato's energy and protein requirements. Justify your answer
What will be an ideal response?
Ireton-Jones: 5W – 11A + 244 + 1784
(5 x 55.5) – (11 x 65) + 244 + 1784
277.5 – 715 + 244 + 1784 = 1590.5 or 1600 kcal
Penn State (2003b) 1189 kcal x 1.2 x 1.3 = 1854 kcal
American Chest Physician's Equation 30-35 kcal/kg/current weight 1663 kcal – 1940 kcal
s
• As the clinician, suggest the range of 1600-1700 kcal.
• The preferred method would be to use indirect calorimetry to obtain measured energy requirements rather than calculated or estimated energy requirements.
• The range of 1.2-1.5 g protein/kg is appropriate as an estimation of protein requirements.
• Since Mr. H's albumin and prealbumin are within normal limits, starting with 1.2 g protein/kg is reasonable. 55.5 kg x 1.2-1.5 = 67-83 g protein/day.
