Haemorrhage from major trauma is a significant cause of death worldwide. The UK Defence Medical Service (UK-DMS) has had significant experience in managing severely injured and shocked trauma casualties over the last decade. This has led to the integration of rotational thromboelastometry (ROTEM) into damage control resuscitation delivered at Camp Bastion Field Hospital in Afghanistan. This review aims to describe the rationale for its use and how its use has evolved by UK-DMS. ⋯ ROTEM provides a means to rapidly assess coagulation in trauma casualties, allowing targeted use of blood products. It provides information on clot initiation strength and breakdown. However, its use in trauma has still to be fully evaluated.

This article reviews the latest operative trauma surgery techniques and strategies, which have been published in the last 10 years. Many of the articles we reviewed come directly from combat surgery experience and may be also applied to the severely injured civilian trauma patient and in the context of terrorist attacks on civilian populations. ⋯ The last 10 years of conflict has produced a wealth of experience and novel techniques in operative trauma surgery. The articles we review here are essential for the contemporary care of the severely injured trauma patient, whether they are card for in a level 1 trauma center or in a field hospital at the edge of a battlefield.

Although early acute traumatic coagulopathy has received much recent attention, the procoagulopathy that often follows appears less appreciated. Thromboembolic disease following trauma is common and lethal, but very effective prophylactic strategies are available. These strategies are variably implemented because of the difficulty in quantifying the magnitude of procoagulopathy in individual patients. ⋯ The logical next step following from the improved pathophysiological understanding of the procoagulopathy of trauma should be a simultaneous clinical trial of procoagulopathy diagnosis and thromboembolic prophylaxis.

Comparative Study
Evaluation of noninvasive hemoglobin measurements in trauma patients.
Reliable, accurate, noninvasive, and continuous determination of hemoglobin would be an important advance in the care of trauma patients. The aim of this study was to evaluate the utility of the Masimo Radical 7 device in severely injured trauma patients. ⋯ The Masimo Radical 7 system evaluated in this study holds promise, but it is not ready to be used as an initial noninvasive evaluation tool in the acute treatment of severely injured trauma patients. There was a poor correlation between Masimo hemoglobin and laboratory hemoglobin and large numbers of missing data. On the basis of the poor correlation, the Masimo Radical 7 device cannot currently be used to guide transfusion therapy.

Hypovolaemic shock that results through traumatically inflicted haemorrhage can have disastrous consequences for the victim. Initially the body can compensate for lost circulating volume, but as haemorrhage continues compensatory mechanisms fail and the patient's condition worsens significantly. Hypovolaemia results in the lethal triad, a combination of hypothermia, acidosis and coagulopathy, three factors that are interlinked and serve to worsen each other. ⋯ This method is easy to implement requiring simple protocols and contributes significantly to interrupting the lethal triad. However, the future of trauma care appears to lie with clinically induced therapeutic hypothermia. This new treatment provides optimism that in the future the number of deaths resulting from catastrophic haemorrhaging may be significantly lessened.
