ReviewThe use of new procoagulants in blunt and penetrating trauma.
Uncontrolled bleeding in trauma secondary to a combination of surgical bleeding and trauma-induced complex coagulopathy is a leading cause of death. Prothrombin complex concentrates (PCCs), recombinant activated factor seven (rFVIIa) and recombinant human prothrombin act as procoagulants by increasing thrombin generation and fibrinogen concentrate aids stable clot formation. This review summarizes the current evidence for procoagulant use in the management of bleeding in trauma, and data and evidence gaps for routine clinical use. ⋯ There is increasing evidence that early correction of coagulopathy has survival benefits, and the use of procoagulants as first-line therapy has the potential benefit of rapid access and timely treatment. This requires confirmation in prospective studies.

Anticoagulants in general, but especially the relatively new direct oral anticoagulants and platelet inhibitors, pose a great challenge for physicians in the hemorrhaging patient. The aim of the present review is to provide an overview on recent studies dealing with the reversal of anticoagulation in the hemorrhaging patient and to describe our therapeutic emergency strategy for those patients. ⋯ To reverse anticoagulation in the hemorrhaging patient, specific antidotes should be the first option if available, followed by four-factor prothrombin complex concentrate (PCC), activated PCC and recombinant activated factor seven as the emergency strategy. Fibrinogen concentrate, antifibrinolytics and oral charcoal, respectively, can be considered as an additional measure. Massive blood loss and thrombocytopenia should be treated independently according to the respective, local guidelines for (massive) transfusion of blood and blood products.

ReviewExtra corporeal membrane oxygenation in the critical trauma patient.
The purpose of this review is to describe recent evidence regarding the use of extracorporeal membrane oxygenation (ECMO) as salvage therapy for severe cardiac or respiratory failure in patients with trauma. The characteristics of this cohort of patients, including the risk of bleeding and the need for systemic anticoagulation, are generally considered as relative contraindications to ECMO treatment. However, recent evidence suggests that the use of ECMO should be taken in consideration even in this group of patients. ⋯ ECMO can be considered as a safe rescue therapy even in trauma patients, including neurological injury, chest trauma as well as burns. However, evidence is still poor; further studies are warranted focusing on trauma patients undergoing ECMO, to better clarify the effect on survival, the type and dose of anticoagulation to use, as well as the utility of dedicated multidisciplinary trauma-ECMO units.

ReviewWithholding or withdrawing life support versus physician-assisted death: a distinction with a difference?
Withholding or withdrawing life-sustaining therapy is generally differentiated from physician-assisted suicide or euthanasia based on the distinction between intention and foresight. We reviewed the literature surrounding the validity of this distinction. ⋯ Several reasons may be given in favor of the distinction between intention and foresight. Given this distinction, the moral permissibility of withholding or withdrawing life-sustaining therapy does not necessarily entail the moral permissibility of physician-assisted suicide or euthanasia.

ReviewTime-efficient, goal-directed, and evidence-based teaching in the ICU.
Teaching in the stressful, high-acuity environment of the ICU is challenging. The intensivist-educator must use teaching strategies that are both effective and time-efficient, as well as evidence-based approaches to the ICU curriculum. This review provides an overview of pertinent educational theories and their implications on educational practices, a selection of effective teaching techniques, and a review on feedback. ⋯ Direct teaching should be goal-oriented, sequential, and adjusted to the level of the learner. The ICU curriculum should optimize cognitive load, reduce stress that is unrelated to the activity, include resilience training, and help trainees deal with stressful clinical situations better. Simulation is a powerful tool to promote technical and nontechnical skills. Providing feedback is essential and a skill that can be taught and enhanced with structure, prompts, and tools.
