Equations of Meyer et al for Estimating Energy Requirements of a Ventilated Critically-Ill Pediatric Patient: Equations A

Description

Meyer et al reported several equations for predicting energy requirements for a pediatric patient who is being ventilated in the intensive care unit (ICU). The authors are from Imperial College London, University of Crete, South Bank University and Paediatric Intensive Care Unit London.

Patient: pediatric patient on ventilator in ICU, <= 18 years of age

Parameters:

(1) weight in kilograms

(2) age in years

(3) diagnostic category

(4) diagnostic category for weight

Parameter	Finding	Points
diagnostic category	multiorgan failure	226
	respiratory failure	79
	CNS disorder	33
	surgery	0
diagnostic category for weight	multiorgan failure	18 * (weight)
	respiratory failure	8 * (weight)
	CNS disorder	10 * (weight)
	surgery	0 * (weight)

estimated energy requirements in kcal/day if < 3 years of age =

= (48.4 * (weight)) - (0.377 * ((weight)^2)) + (1.22 * (age)) + (6.2 * (age)) + (points for diagnosis category) - (points for diagnostic category for weight) + 309 - 283.7

estimated energy requirements in kcal/day if 3 to 10 years of age =

= (48.4 * (weight)) - (0.377 * ((weight)^2)) + (1.22 * (age)) - (7.6 * (age)) + (points for diagnosis category) - (points for diagnostic category for weight) + 309 + 259

estimated energy requirements in kcal/day if 11 to 18 years of age =

= (48.4 * (weight)) - (0.377 * ((weight)^2)) + (1.22 * (age)) + (points for diagnosis category) - (points for diagnostic category for weight) + 309
