Abstract EN
Nutrition is essential in critically ill patients, but translating caloric prescriptions into adequate caloric intake remains challenging.
Caloric prescriptions (P), effective intake (I), and caloric needs (N), calculated with modified Harris-Benedict formulas, were recorded during seven consecutive days in ventilated patients.
Adequacy of prescription was estimated by P/N ratio.
I/P ratio assessed accuracy of translating a prescription into administered feeding.
I/N ratio compared delivered calories with theoretical caloric needs.
Fifty patients were prospectively studied in a mixed medicosurgical ICU in a teaching hospital.
Basal and total energy expenditure were, respectively, 1361±171 kcal/d and 1649±233 kcal/d.
P and I attained 1536±602 kcal/d and 1424±572 kcal/d, respectively.
24.6% prescriptions were accurate, and 24.3% calories were correctly administered.
Excessive calories were prescribed in 35.4% of patients, 27.4% being overfed.
Caloric needs were underestimated in 40% prescriptions, with 48.3% patients underfed.
Calculating caloric requirements by a modified standard formula covered energy needs in only 25% of long-term mechanically ventilated patients, leaving many over- or underfed.
Nutritional imbalance mainly resulted from incorrect prescription.
Failure of “simple” calculations to direct caloric prescription in these patients suggests systematic use of more reliable methods, for example, indirect calorimetry.
