Erythrocyte blood transfusions are commonly used in intensive care units, yet little is known about their effects on long-term survival. ⋯ Blood transfusion was associated with a decreased risk of late (>180 days) death in intensive care patients.

High-frequency oscillatory ventilation is an alternative ventilation mode that improves oxygenation in trauma patients in whom conventional ventilation strategies have been unsuccessful. ⋯ Although high-frequency oscillatory ventilation improves oxygenation, severity of traumatic injury and organ failure, not respiratory parameters, are predictors of survival. High-frequency oscillatory ventilation should be considered for pulmonary rescue of severely injured patients with acute respiratory distress syndrome.

Critically ill patients often require sedation and analgesia. Scales have been developed to provide clinicians with sedation targets. Daily interruption of continuous infusions of sedatives and sedation protocols improve patients' outcomes. However, perceived instability of a patient's condition can prevent implementation of appropriate sedation targets and daily interruption of sedation. ⋯ The severity-of-illness score had good interrater variability as a tool for determining sedation targets and identifying candidates for daily interruption of sedation. Future study on how use of the score affects sedative dosing and outcomes is needed.
