ReviewElectrical impedance tomography in adult patients undergoing mechanical ventilation: A systematic review.
The purpose of the study is to systematically review and summarize current literature concerning the validation and application of electrical impedance tomography (EIT) in mechanically ventilated adult patients. ⋯ In adult patients, EIT has been successfully validated for assessing ventilation distribution, measuring changes in lung volume, studying regional respiratory mechanics, and investigating nonventilatory parameters. Electrical impedance tomography has also been demonstrated to be useful in monitoring regional respiratory system changes during MV interventions, although existing literature lacks clinical outcome evidence.

Randomized Controlled TrialHigh-protein hypocaloric vs normocaloric enteral nutrition in critically ill patients: A randomized clinical trial.
Appropriate caloric intake in critically ill patients receiving enteral nutrition is controversial. This study evaluates the impact of different caloric regimens on severity of organ failure measured with Sequential Organ Failure Assessment (SOFA). ⋯ Hyperproteic, hypocaloric nutrition did not show different outcomes compared to normocaloric nutrition, except lower insulin requirements. Hypocaloric nutrition could provide a more physiologic approach with lower need for care and metabolic impact.

Multicenter StudyEffects of propofol on vasopressor use in patients with sepsis and severe sepsis: A pilot study.
Propofol is one of the most commonly used sedatives in the intensive care unit (ICU) despite its undesirable hypotensive effects. The purpose of this study was to determine the effects of continuous intravenous (CIV) propofol on vasopressor requirements in mechanically ventilated patients with sepsis. ⋯ Continuous intravenous propofol for sedation did not increase vasopressor requirements in this septic population. Furthermore, CIV propofol was not associated with significant differences in the use of multiple vasopressors, change in mean arterial pressure, length of stay, or mortality.
