Randomized Controlled Trial Clinical TrialChanges in whole body and tissue oxygen consumption during recovery from hypothermia: effect of amino acid infusion.
To study the effects of amino acids on whole body and peripheral energy metabolism during recovery from post-operative hypothermia. ⋯ The amino acid infusions had no effect on the leg uptake of glucose, ketone bodies, and pyruvate and the leg release of lactate, free fatty acids, and triglycerides, which remained constant during the study.

Objective assessment of changing mortality risks in pediatric intensive care unit patients.
To develop and validate a mortality risk predictor based on physiologic data that estimates daily the probability of a patient dying within the next 24 hrs as that probability changes with disease and recovery. ⋯ The predictor is valid for assessing the 24-hr mortality risk in pediatric ICU patients hospitalized in other tertiary care institutions, different from those used for predictor development. The predicted mortality risks allow prospective patient stratification into risk groups. The ability of this predictor to follow risk changes over time expands its applicability over static predictors by enabling the charting of patient courses, and permitting ICU efficiency analysis.

Clinical TrialUse of femoral venous catheters in critically ill adults: prospective study.
To determine the frequency of clinically important complications of femoral venous catheters. ⋯ Femoral venous catheterization offers an alternative site of insertion to the subclavian and jugular veins for central venous access in the critically ill. The occurrence rate of clinically important complications is acceptably low.

ReviewIs it time to use evoked potentials to predict outcome in comatose children and adults?
To determine the value of multimodality-evoked potential recordings in predicting outcome in comatose children. ⋯ A bad outcome can be reliably predicted using multimodality-evoked potential recordings with little chance of a false pessimistic prediction. The acceptable error of false optimism occurs frequently, since patients often die of progressive neurologic and nonneurologic problems that may or may not be present at the time of the evoked potential recordings. Thus, in comatose children, multimodality-evoked potential recordings are a useful adjunct to clinical examination and other diagnostic aids in predicting outcome and in making decisions regarding the degree of intervention to offer.

To assess the resting energy expenditure of hospitalized patients with pancreatitis. ⋯ Resting energy expenditure is variable in patients with pancreatitis (77% to 139% of predicted energy expenditure). The Harris-Benedict equations are an unreliable estimate of caloric expenditure. Septic complications are associated with hypermetabolism and may be the most important factor influencing resting energy expenditure in pancreatitis patients.
