Review Comparative StudyUltrasonography of the brachial plexus, normal appearance and practical applications.
Ultrasound examination of the brachial plexus, although at first sight difficult, is perfectly feasible with fairly rapid practical and theoretical training. The roots are accurately identified due to the shape (a single tubercle) of the transverse process of C7 in the paravertebral space, and the superficial position of C5 in the interscalene groove. ⋯ In trained hands, it also provides information in thoracic outlet syndromes, traumatic conditions (particularly for postganglionic lesions) and tumoral diseases. Even if MRI remains the standard examination in these indications, ultrasound, with its higher definition and dynamic character, is an excellent additional method which is still under-exploited.

Multicenter Study
Tourniquet use for peripheral vascular injuries in the civilian setting.
Haemorrhage in peripheral vascular injuries may cause life-threatening exsanguination. Tourniquets are used extensively by the military, with increased interest in the civilian setting to prevent deaths. This is a retrospective study of trauma patients at two large Canadian trauma centres with arterial injury after isolated extremity trauma. We hypothesized that tourniquet use may decrease mortality rate and transfusion requirements if applied early. ⋯ Tourniquets may prevent exsanguination in the civilian setting for patients suffering either blunt or penetrating trauma to the extremity. Future studies will help determine the utility of deploying tourniquets in the civilian setting, given the rarity of exsanguinating haemorrhage from isolated extremity trauma in this setting.

ReviewTherapeutic Hypothermia in Children and Adults with Severe Traumatic Brain Injury.
Great expectations have been raised about neuroprotection of therapeutic hypothermia in patients with traumatic brain injury (TBI) by analogy with its effects after heart arrest, neonatal asphyxia, and drowning in cold water. The aim of this study is to review our present knowledge of the effect of therapeutic hypothermia on outcome in children and adults with severe TBI. A literature search for relevant articles in English published from year 2000 up to December 2013 found 19 studies. ⋯ The difference between body temperature and temperature set by the biological thermostat may cause stress-induced worsening of the circulation and oxygenation in injured areas of the brain. These mechanisms may counteract neuroprotective effects of therapeutic hypothermia. We conclude that we still lack scientific support as a first-tier therapy for the use of therapeutic hypothermia in TBI patients for both adults and children, but it may still be an option as a second-tier therapy for refractory intracranial hypertension.

Randomized Controlled TrialComparison of diagnostic peritoneal lavage and focused assessment by sonography in trauma as an adjunct to primary survey in torso trauma: a prospective randomized clinical trial.
Lately, Focused Assessment with Sonography in Trauma (FAST) is preferred over diagnostic peritoneal lavage (DPL) as adjunct to primary survey. However, this is not evidence-based as there has been no randomized trial. ⋯ This study shows that DPL is better than FAST.

Admission hypocoagulability has been associated with negative outcomes after trauma. The purpose of this study was to determine the impact of hypercoagulability after trauma on the need for blood product transfusion and mortality. ⋯ Approximately a quarter of trauma patients presented in a hypercoagulable state. Hypercoagulable patients required less blood products, in particular plasma. They also had a lower 24-h and 7-day mortality and lower rates of bleeding-related deaths. Further evaluation of the mechanism responsible for the hypercoagulable state and its implications on outcome is warranted.
