- W2000916867 abstract "Abstract Nutritional status influences the patient's ability to wean from mechanical ventilation. Calculation of resting energy expenditure may not provide estimations that reflect additional stress imposed by factors such as mechanical ventilation. A retrospective analysis of 37 mechanically ventilated patients examined agreement between two methods of estimating resting energy expenditure: predicted values of resting energy expenditure obtained with the Harris-Benedict equation (PREE) and measured values obtained with indirect calorimetry (MEE). Relationships between nutritional variables and ability to wean were measured. Selected variables analyzed were significantly different between patients who weaned (W) and patients who did not wean (NW). Weight, percentage of ideal body weight (PIBW), PREE,) were tested. In this sample, PREE was not significantly different from MEE (p. > .05). Admission weight entered the stepwise logistic regression model (p = .003, df=30) indicating that adding this variable significantly improved the prediction of success or failure to wean. Separate analysis was done on survivors (n = 15). Differences were noted between W and NW groups in the variables of negative inspiratory force (NIF) p≤.05, weight, both admission and discharge, p≤.01, PIBW, p Implications for Dietetic practice may include selectively monitoring nutritional variables associated with positive weaning outcomes." @default.
