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.

Three important issues concerning homeostasis in the acute care of trauma patients that are related directly to the stress response are hyperglycemia, lactic acidosis, and hypothermia. Recently, there has been a resurgence of interest in investigating the effects of aggressive thermal and glucose concentration and volume resuscitation on outcomes in critically ill and trauma patients. Significant reason exists to question the "conventional wisdom" relating to current approaches to restoring homeostasis in this patient population.

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.

Intraoperative monitoring with transesophageal echocardiography: indications, risks, and training.
There are benefits and risks to the use of TEE. The benefits are derived from the physiologic information that TEE provides, which may not be as readily obtained by any other technique. The risks of TEE are those related to mechanical trauma from the probe, as well as those of an incorrect TEE interpretation by the echocardiographer. ⋯ The authors have discussed some of the issues involved with each class-I indication. Performance of the TEE is not an end in itself and should not distract the anesthesiologist from the primary goal of patient care. With proper training and experience, the anesthesiologist may learn how to use TEE to improve patient care.

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.
