Critical care : the official journal of the Critical Care Forum
-
The present article summarises and places in context original research articles from the respirology section published in Critical Care in 2006. Twenty papers were identified and were grouped by topic into those addressing acute lung injury and ventilator-induced lung injury, those examining high-frequency oscillation, those studying pulmonary physiology and mechanics, those assessing tracheostomy, and those exploring other topics.

Review
Clinical review: initial management of blunt pelvic trauma patients with haemodynamic instability.
Pelvic trauma can lead to severe, uncontrollable haemorrhage and death related to prolonged shock and multiple organ failure. Massive retroperitoneal haematoma should be assumed to be present in cases of post-traumatic haemodynamic instability associated with pelvic fracture in the absence of extrapelvic haemorrhagic lesions. ⋯ Efficacy and safety of haemostatic procedures are also discussed, and particular attention is given to the efficacy of pelvic angiographic embolization and external pelvic fixation. A decision making algorithm is proposed for the treatment of trauma patients with pelvic fracture that takes haemodynamic status and associated lesions into account.

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.

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.

Randomized Controlled Trial Multicenter Study
RESOLVE-ing sepsis in children--not yet!
The Researching Severe Sepsis and Organ Dysfunction in Children: A Global Perspective study of drotrecogin alpha activated versus placebo was the largest study of adjunctive therapy ever performed in children with severe sepsis. Despite this, the study failed to show any significant differences in outcome between the treatment and placebo groups. The results raise questions about how we should perform meaningful clinical trials in relatively rare conditions such as paediatric sepsis, where the easily measurable endpoints (such as death) are infrequent. A radical rethink of the design of such studies is urgently needed.
