The current gold standard for the diagnosis of elevated intracranial pressure (ICP) remains invasive monitoring. Given that invasive monitoring is not always available or clinically feasible, there is growing interest in non-invasive methods of assessing ICP using diagnostic modalities such as ultrasound or magnetic resonance imaging (MRI). ⋯ They report a positive correlation between measurements of the ONSD on MRI and invasive ICP measurements. If the findings of this study can be replicated in larger populations, this technique may be a useful non-invasive screening test for elevated ICP in select populations.

Improving survival by increasing lung edema clearance: is airspace delivery of dopamine a solution?
In this issue of Critical Care Chamorro-Marin and coworkers provide new evidence that dopamine instilled into airspaces is beneficial in a rat model of ventilator-induced lung injury. This study is important because it is the first to explore the effects of dopamine on survival, albeit short term. ⋯ Dopamine appears to increase active Na+ transport via activation of amiloride-sensitive sodium channels and the basolateral Na+/K+-ATPase within minutes, and it has been shown to be effective in normal lungs and several models of lung injury. This information is relevant to current clinical trials exploring the effects of alveolar fluid clearance stimulation in patients with acute lung injury.

Multicenter Study Comparative Study
Prevalence of sleep disturbances and long-term reduced health-related quality of life after critical care: a prospective multicenter cohort study.
The aim of the present prospective multicenter cohort study was to examine the prevalence of sleep disturbance and its relation to the patient's reported health-related quality of life after intensive care. We also assessed the possible underlying causes of sleep disturbance, including factors related to the critical illness. ⋯ There is little change in the long-term quality of sleep patterns among hospitalised patients with an ICU stay. This applies both to the comparison before and after critical care as well as between 6 and 12 months after the ICU stay. Furthermore, sleep disturbances for this group are common. Concurrent disease was found to be most important as an underlying cause, which emphasises that it is essential to include assessment of concurrent disease in sleep-related research in this group of patients.
