Brief summary
The aim of this study is to perform a prospective, randomized, controlled blinded study in critically patients to assess the necessity for measuring daily resting energy expenditure as a guide for nutritional support. Our hypothesis is that tight caloric control will reduce the rate of new infections. Study Design :Multi-center, randomized, single blinded, controlled study. Study Population: newly-admitted, adult mechanically ventilated ICU patients.
Detailed description
Study objectives To evaluate the effect of tight caloric control in critical patients on: * The rate of acquired nosocomial infections (Ventilated associated pneumonia, Catheter related infections, Urinary tract infections) * Mortality rates, length of stay in the ICU and in hospital, length of ventilation and incidence of non-infectious complications. Primary endpoint: Rate of nosocomial infections (for definitions see appendage 1) acquired after 48 to 72 hours following admission. Secondary endpoints * Metabolic control: glucose concentration, insulin administration, rate of hypoglycemic events. * Success of tight caloric control: accumulative and maximum negative energy balance. * Organ function: SOFA score. * Rate of non-infectious complications: requirement for surgery or occurrence of pressure sores. * Length of ICU stay and of assisted ventilation (LOS and LOV) * ICU survival rate. * Patient status and disposition on day 28 or at hospital discharge. * 3 & 6 months survival.
Interventions
DIETARY_SUPPLEMENTIndirect Calorimetry measurement of Resting Energy Expenditure .
Patients in this group will receive enteral nutrition/parenteral nutrition or combination of enteral and parenteral nutrition according to the individual energy requirements calculated by Indirect Calorimetry.
