ReviewNew issues in severity scoring: interfacing the ICU and evaluating it.
Since the development of the first general outcome prediction models, these instruments have been widely used in the intensive care unit (ICU), both for patient evaluation and for ICU evaluation. Since some of these uses have been serious questioned, we assisted in the last years to the exploration of alternative paths for increasing the predictive power of the models and to enhance their applicability and utility in the real world. ⋯ Also, since it is now widely recognized that the ICU is not an island, but it is integrated in a continuum of care, more and more efforts are being made to optimize and evaluate the interface between the ICU and the hospital, both at ICU admission and at ICU discharge. The objective of this review is to present and discuss, to the clinician working in the ICU, these emerging issues.

ReviewTermination of resuscitative efforts: medical futility for the trauma patient.
Despite years of research on the resuscitation of the patient with critical traumatic injuries, controversy remains surrounding the criteria to waive initiation of resuscitation in the pre-hospital setting or to terminate such efforts in the emergency department. The decision to initiate or continue resuscitation on moribund trauma patients is associated with considerable costs. ⋯ This review presents guidelines to help determine when to initiate resuscitation for the critically injured trauma patient and when to cease these efforts in the emergency department. Since there are economic, societal, and ethical implications, each system should establish their own criteria, using these guidelines as a basis.

ReviewPrehospital and resuscitative airway care: should the gold standard be reassessed?
In the context of prehospital care and resuscitation, tracheal intubation has been regarded as the standard in airway treatment. The evidence for this status is rather weak. ⋯ When healthcare providers lack adequate skills in tracheal intubation, alternative airway devices, such as the laryngeal mask airway or the Combitube, may be better options than a simple facemask. Healthcare personnel using any of these devices should be adequately trained and maintain frequent practice.

ReviewLow-volume fluid resuscitation for presumed hemorrhagic shock: helpful or harmful?
For the past 4 decades, the standard approach to the trauma victim who is hypotensive from presumed hemorrhage has been to infuse large volumes of fluids as early and as rapidly as possible. The goals of this treatment strategy are rapid restoration of intravascular volume and vital signs towards normal, and maintenance of vital organ perfusion. The most recent laboratory studies and the only clinical trial evaluating the efficacy of these guidelines however, suggest that in the setting of uncontrolled hemorrhage, today's practice of aggressive fluid resuscitation may be harmful, resulting in increased hemorrhage volume and subsequently greater mortality. ⋯ Limited resuscitation provides a mechanism of avoiding the detrimental effects associated with early aggressive resuscitation, while maintaining a level of tissue perfusion that although decreased from the normal physiologic range is adequate for short periods. Large randomized clinical trials are necessary to confirm this new laboratory data. Future research should focus on developing resuscitation methods that may actually enhance tissue perfusion during limited resuscitation and therefore offset its potential detrimental effects.

ReviewPrehospital and resuscitative care of the head-injured patient.
The ultimate neurologic outcome following severe head trauma depends on the extent of primary brain insult sustained at the time of the trauma itself, and the subsequent neurochemical and neurophysiologic pathologic changes occurring as a result of the injury. Although there are currently no specific therapies that have proven to be consistently effective in reversing the devastating consequences of primary brain insult, the reduction or prevention of secondary brain insult is possible. ⋯ As new data are accumulated, traditional and new therapies for severe head injury have come under scrutiny. While no absolute standards have been advanced, guidelines have been established that can help direct the acute stabilization of severely head injured patients.
