A substantial body of literature concerning resuscitation from cardiac arrest now exists. However, not surprisingly, the greater part concerns the cardiac arrest event itself and optimising survival and outcome at relatively proximal time points. ⋯ In addition, this paper reviews the data on long-term impact, physical and neuropsychological, on patients and their families, revealing a burden that is often underestimated and underappreciated. As greater numbers of patients survive cardiac arrest, outcome measures more sophisticated than simple survival are required.

In patients with acute respiratory distress syndrome, positive end-expiratory pressure is associated with alveolar recruitment and lung hyperinflation despite the administration of a low tidal volume. The best positive end-expiratory pressure should correspond to the best compromise between recruitment and distension, a condition that coincides with the best respiratory elastance.

In 2006, paediatric intensive care-related subjects were discussed in a number of papers published in various journals, including Critical Care. Because they focused on the cardiovascular system and its support, we summarize them here. In particular, these papers highlighted the management of refractory septic shock, extracorporeal support, outcome markers in sepsis, and outcome after cardiac arrest.

Review
Clinical review: Prognostic value of magnetic resonance imaging in acute brain injury and coma.
Progress in management of critically ill neurological patients has led to improved survival rates. However, severe residual neurological impairment, such as persistent coma, occurs in some survivors. This raises concerns about whether it is ethically appropriate to apply aggressive care routinely, which is also associated with burdensome long-term management costs. ⋯ In addition, there is some evidence that MRI may have potential in terms of predicting outcome. Following a brief description of the sequences used, this review focuses on the prognostic value of MRI in patients with traumatic brain injury, anoxic/hypoxic encephalopathy and stroke. Finally, the roles played by the main anatomical structures involved in arousal and awareness are discussed and avenues for future research suggested.

Multicenter Study Comparative Study
Changes in sedation management in German intensive care units between 2002 and 2006: a national follow-up survey.
The aim of this study, conducted in 2006, was to find out whether changes in sedation management in German intensive care units took place in comparison with our survey from 2002. ⋯ The increased implementation of protocols and scoring systems for the measurement of sedation depth and analgesia, a daily sedation break, and the use of more short-acting analgesics and sedatives account for more patient-oriented analgesia and sedation in 2006 compared with 2002.
