Prehospital Lyophilized Plasma Transfusion for Trauma-Induced Coagulopathy in Patients at Risk for Hemorrhagic Shock

International audienceIMPORTANCE Blood transfusion is a mainstay of therapy for trauma-induced coagulopathy, but the optimal modalities for plasma transfusion in the prehospital setting remain to be defined. OBJECTIVE To determine whether lyophilized plasma transfusion can reduce the incidence of trauma-induced coagulopathy compared with standard care consisting of normal saline infusion. DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial was performed at multiple centers in France involving prehospital medical teams. Participants included 150 adults with trauma who were at risk for hemorrhagic shock and associated coagulopathy between April 1, 2016, an

Intracranial Pressure and Multimodal Monitoring

Secondary brain injury results from ischemia, tissue hypoxia, and a cascade of ongoing metabolic events. Neuromonitoring has evolved over the last two decades with the goal of preventing, detecting, and attenuating the damage from these secondary events. Typical monitored parameters include intracranial pressure (ICP) and cerebral perfusion pressure (CPP). Advanced multimodal monitoring includes monitoring of cerebral blood flow (CBF), brain tissue oxygenation (transcranial oximetry, jugular bulb oximetry, brain tissue oxygen tension), and brain metabolism (intracerebral microdialysis). In this chapter, we will review basic principles of brain physiology and the complex and dynamic interactions between these parameters. In the future, neuromonitoring will be supported by advanced signal processing and analysis that will enable clinicians to synthesize information and form hypotheses that best explain the current situation. Such an integrated system will translate data into actionable information and provide situational awareness
