Role of the physician in prehospital management of trauma: European perspective.
Advanced prehospital trauma life support is challenged as a whole. Formerly well-accepted basic principles for stabilizing vital functions of the severely injured patient like volume resuscitation, airway protection, and immobilization have been questioned. In prehospital management of trauma, the role of not only the physician but also the paramedic must be redefined. ⋯ Invasive airway management techniques require skills, expertise, and daily routines available only to experienced in-hospital personnel. The controversial issue of paramedic vs physician-based systems should be abandoned. It is the skill, the technique, the awareness of pitfalls, and the capability to handle complications that makes the difference, not the person in possession of the skill.

The evaluation and management of acute renal failure in the ICU patient remains a formidable task because of the complexity of this condition. Clinical and physiologic assessment and complementing laboratory and imaging tests are currently insufficient to differ between true renal parenchymal damage (acute tubular necrosis; it is important to realize that this term does not necessarily imply widespread injury, because whole organ dysfunction in humans has often been associated with very limited parenchymal cellular necrosis) and prerenal azotemia (decreased renal blood flow with altered glomerular hemodynamics and subsequently diminished glomerular filtration, without significant epithelial cell injury). Moreover, tubular damage and altered glomerular hemodynamics may coexist or lead to each other, and their relative contribution to the evolving renal dysfunction has not been unequivocally established. ⋯ Because of the difficulties in analyzing the pathophysiology in humans, clinicians continue to rely largely on animal models to guide understanding and rationale for the identification of therapeutic targets. Data from such animal studies are complemented by studies in isolated perfused kidneys, isolated tubules, and tubular epithelial cell cultures. In this report, we summarize some concepts of acute tubular necrosis that have evolved as a result of these studies, evaluate available animal models, and underscore controversies regarding experimental acute tubular necrosis.

ReviewEarly intensive care unit intervention for trauma care: what alters the outcome?
This review focuses on early management of multiple trauma patients with traumatic brain injury. Early usage of multislice computed tomography can substantially shorten the time spent on diagnostic workup in the emergency room and, therefore, speeds the initiation of lifesaving interventions for the control of hemorrhage. The important role of hemostatic angiographic embolization and its timing, in addition to surgical control of bleeding in patients suffering from pelvic fracture or organ lesions, is emphasized. ⋯ A novel approach to reduce major bleeding is the application of recombinant factor VIIa. Strong effort should be directed toward the management of traumatic brain injury and the maintenance of cerebral perfusion pressure. The optimization of treatment of patients with multiple trauma, including brain injury, is a multidisciplinary task.

ReviewClinical information systems and the electronic medical record in the intensive care unit.
The integration of computers into critical care is by no means a new concept. Clinical information systems have evolved in the critical care setting over the past three decades. ⋯ Clinical information systems and the electronic medical record in the ICU have the potential to improve medical record movement problems, to improve quality and coherence of the patient care process, to automate guidelines and care pathways, and to assist in clinical care and research, outcome management, and process improvement. In this article, we provide some historical background on the clinical information system and the electronic medical record and describe their current utilization in the ICU and their role in the practice of critical care medicine in decades to come.

ReviewSpinal immobilization in trauma patients: is it really necessary?
The acute management of potential spinal injuries in trauma patients is undergoing radical reassessment. Until recently, it was mandatory that nearly all trauma patients be immobilized with a back board, hard cervical collar, head restraints, and body strapping until the spine could be cleared radiologically. This practice is still recommended by many references. ⋯ Low-risk patients can be safely cleared clinically, even by individuals who are not physicians. Patients at high risk for spinal instability should be removed from the hard surface to avoid tissue ischemia. Understanding the rationale for these changes requires knowledge of mechanisms of injury, physiology, and biomechanics as they apply to spinal injuries.
