Energy expenditure estimation in recipients of marrow transplants

Abstract

The resting metabolic expenditure of seven allogeneic marrow transplant patients supported by total parenteral nutrition was monitored by respiratory indirect calorimetry using a portable apparatus with a plexiglass canopy. The averaged measurements of resting metabolic expenditure using indirect calorimetry were highly correlated with calculated basal energy expenditures, ideal body weights, fat‐free weights, and actual body weights. No consistent correlation was demonstrated between resting metabolic expenditure and body temperature. It is concluded that indirect calorimetry using a portable system is feasible and that measurements of energy expenditure so obtained correlate well with calculated estimates employing the basal energy expenditure equation.
