There have been many recent advances in the management of traumatic brain injury (TBI). Research regarding established and novel therapies is ongoing. ⋯ In addition, the impact of these advances on varying severities of brain injury must not be ignored. It is hoped that future research strategies in TBI will prioritize large-scale trials using common data elements to develop large registries and databases, and leverage international collaborations.

Hemorrhage is the leading cause of preventable death in trauma. Damage control resuscitation relies on permissive hypotension, minimizing crystalloid use, and early implementation of massive transfusion protocols with established blood component ratios. These protocols improve the survival of the severely injured patient. ⋯ Several validated transfusion scores have been developed for this purpose. Many of these scores are useful for resuscitation research. One option, the ABC score, is an accurate, validated, and clinically useful score that is simple to calculate and rapidly obtained.

ReviewManagement of Trauma-Induced Coagulopathy with Thrombelastography.
Viscoelastic assays, such as thrombelastography (TEG) and rotational thrombelastometry (ROTEM), have emerged as point-of-care tools that can guide the hemostatic resuscitation of bleeding injured patients. This article describes the role of TEG in contemporary trauma care by explaining this assay's methodology, clinical applications, and result interpretation through description of supporting studies to provide the reader with an evidence-based user's guide. Although TEG and ROTEM are assays based on the same viscoelastic principle, this article is focused on data supporting the use of TEG in trauma, because it is available in trauma centers in North America; ROTEM is mostly available in Europe.

The resuscitation of traumatic hemorrhagic shock has undergone a paradigm shift in the last 20 years with the advent of damage control resuscitation (DCR). Major principles of DCR include minimization of crystalloid, permissive hypotension, transfusion of a balanced ratio of blood products, and goal-directed correction of coagulopathy. In particular, plasma has replaced crystalloid as the primary means for volume expansion for traumatic hemorrhagic shock. Predicting which patient will require DCR by prompt and accurate activation of a massive transfusion protocol, however, remains a challenge.

ReviewResuscitative Endovascular Balloon Occlusion of the Aorta: Indications, Outcomes, and Training.
Exsanguinating torso hemorrhage is a leading killer of trauma patients. The most appropriate means of hemorrhage control must be used. Trauma surgeons should have expertise with all approaches for prompt hemorrhage control [laparotomy, thoracotomy, resuscitative endovascular balloon occlusion of the aorta (REBOA), and resuscitative thoracotomy]. ⋯ Balloon inflation can vary dependent on patient physiology. REBOA is effective in hemorrhagic shock as a bridge to definitive hemostasis. Endovascular training is important for trauma surgeons caring for patients at high risk of death from traumatic hemorrhage.
