ReviewCoagulation monitoring of the bleeding traumatized patient.
Death due to trauma is the leading cause of lost life years worldwide, with haemorrhage being responsible for 30-40% of trauma mortality and accounting for almost 50% of the deaths in the initial 24 h. On admission, 25-35% of trauma patients present with coagulopathy, which is associated with a several-fold increase in morbidity and mortality. ⋯ This article reviews the basic principles of VHA, the correlation between the VHA whole blood clot formation in accordance with the cell-based model of haemostasis, the current use of VHA-guided therapy in trauma and limitations of VHA.

Opt-in or opt-out consent for organ transplantation is still a disputed subject and the determination of the more appropriate system is still debated. ⋯ Consent for organ donation in a brain dead patient represents an act of benevolence or of solidarity in favour of an unknown person. If one considers that the principle of autonomy must prevail over the principle of benevolence or of solidarity, the risk is depriving a potential recipient of a comparatively very important benefit. On the contrary, if one considers that the principles of benevolence should necessarily lead, the risk is high of exerting an excessive pressure to the detriments of autonomy and liberty of the individual. Whatever the system chosen, adequate and fair communication expressing loyally the way families are approached is essential.

ReviewUltrasound-guided peripheral nerve blockade of the upper extremity.
Is ultrasound guidance changing the practice of upper extremity regional anesthesia? This review will aim to describe the findings published in the literature during the previous 18 months. ⋯ Current literature suggests a reduction of the volume of local anesthetics used for ultrasound-guided upper extremity blockades. Dexamethasone may prolong duration of brachial plexus blocks and more frequent use of perineural catheters is encouraged. Controversy over intra-epineurial injections exists and requires additional large-scale studies.
