ReviewMultiple casualty incidents: the prehospital role of the anesthesiologist in Europe.
The recent increase in incidents involving mass casualties has emphasized the need for a planned and coordinated prehospital emergency medical response, with medical teams on-site to provide advanced trauma life support. The special skills of the anesthesiologist make his/her contribution to prehospital emergency care particularly valuable. ⋯ In contrast, the French approach is based on the use of its emergency care system SAMU, where both structured dispatching and on-site medical care is provided by physicians, including anesthesiologists. In this article, the lessons learned from multiple casualty incidents in Europe during the past 2 decades are considered from the standpoint of the anesthesiologist.

ReviewTraining and assessment of trauma management: the role of simulation-based medical education.
Simulation-based medical education (SBME) offers a safe and "mistake-forgiving" environment to teach and train medical professionals. The diverse range of medical simulation modalities enables trainees to acquire and practice an array of tasks and skills. SBME offers the field of trauma training multiple opportunities to enhance the effectiveness of the education provided in this challenging domain. In this article, the authors describe the possible roles of simulated patients, skills trainers, computerized patient simulators, and web-based teaching in trauma training, and describe some practical aspects of using simulation for trauma training.

Medical and surgical treatment of the trauma patient has evolved in the last decade. Treatment of pain from multiple fractures or injured organs and surgical anesthesia with regional anesthesia techniques have been used to reduce post-traumatic stress disorder and reduce the adverse effects of general anesthesia. ⋯ This article reviews recent publications related to the role of regional anesthesia in trauma patients in the prehospital, emergency, and operatory room settings. It also describes indications, limitations, and practical aspects of regional anesthesia.

Traditionally, hypothermia has been thought of and used perioperatively as a presumptive strategy to reduce cerebral and myocardial tissue sensitivity to ischemia. Evidence, however, is mounting that maintenance of perioperative normothermia is associated with improved outcomes in patients undergoing all types of surgery, even cardiac surgery. Ambient environmental temperature is sensed by free nerve endings in the dermal and epidermal layers of the skin, which are the axonal extensions of thermosensitive neurons found in the dorsal root ganglia. ⋯ Heating intravenous fluids does not warm patients, but does prevent fluid-induced hypothermia in patients given large volumes of fluid. This article examined the evolutionary adaptations people possess to combat inadvertent hypothermia and hyperthermia. Because thermal disturbances are associated with severe consequences, the standard of care is to monitor temperature during general anesthesia and to maintain normothermia unless otherwise specifically indicated.

Depth-of-anesthesia monitoring with EEG or EEG combined with mLAER is becoming widely used in anesthesia practice. Evidence shows that this monitoring improves outcome by reducing the incidence of intra-operative awareness while reducing the average amount of anesthesia that is administered, resulting in faster wake-up and recovery, and perhaps reduced nausea and vomiting. As with any monitoring device, there are limitations in the use of the monitors and the anesthesiologist must be able to interpret the data accordingly. ⋯ Several monitoring devices are commercially available. The BIS monitor is the most thoroughly studied and most widely used, but the amount of information about other monitors is growing. In the future, depth-of-anesthesia monitoring will probably help in further refining and better understanding the process of administering anesthesia.
