Review Case ReportsResuscitation of the multitrauma patient with head injury.
Head injury remains the leading cause of death from trauma. The definitive method for eliminating preventable death from traumatic brain injury remains elusive. New research underscores the danger of inadequate or inappropriate support of oxygenation, ventilation, and perfusion to cerebral tissues. ⋯ A search for optimal treatments based on prospective randomized trials will continue. Development of neuroprotective drugs and use of hypertonic saline may be on the horizon. In an effort to ensure optimal outcome, contemporary trauma nursing must embrace new concepts, shed outmoded therapy, and ensure compliance with the basic tenets of critical care for the multitrauma patient with head injury.

ReviewThe trauma triad of death: hypothermia, acidosis, and coagulopathy.
With the organization of trauma systems, the development of trauma centers, the application of standardized methods of resuscitation, and improvements in modern blood banking techniques, the ability to aggressively resuscitate patients in extremis has evolved. The concept of the "golden hour" has translated into unprecedented speed and efficiency of trauma resuscitation with the ultimate goal of short injury-to-incision times. ⋯ Critical care nurses must understand this triad, because it forms the basis and underlying logic on which the damage control philosophy has been built. This article explores the pathogenesis and treatment of acidosis, hypothermia, and coagulopathy as it applies to the exsanguinating trauma patient.

ReviewTemperature management in trauma patients across the continuum of care: the TEMP Group. Temperature Evaluation and Management Project.
Hypothermia is a potentially preventable consequence of injury in the trauma patient. The physiologic aftermath of hypothermia is such that it is regarded as one of the three components in the trauma triad of death. A multidisciplinary group at a Level I trauma center was formed to originate an innovative team approach to managing temperature in trauma patients. This article describes this unique project to combat a preventable cause of significant morbidity and mortality.

ReviewRight heart volumetric monitoring: measuring preload in the critically injured patient.
Accurate assessment of preload status is a major concern in the resuscitation of the critically injured patient. Of the three physiologic determinants of stroke volume, preload is the variable that is most frequently influenced by an insult or intervention or both in the trauma patient. ⋯ Until recently, efforts to measure and optimize ventricular preload have focused on intracardiac filling pressures (central venous pressure and pulmonary artery occlusion pressure). The purpose of this review is to discuss the application of volumetric measurements that provide a more accurate means of determining recruitable ventricular preload in the critically injured patient.

The critically injured trauma patient in severe hemorrhagic shock presents a complex and arduous challenge to even the most experienced trauma staff. Lives are at stake as trauma teams feverishly pour massive amounts of blood into severely injured patients attempting to replace entire blood volumes several times over. ⋯ Other treatments, such as autotransfusion and blood substitutes, are promising adjunctive therapies that may in the near future help to improve outcomes in patients who require massive blood transfusions. This article reviews the current standard of care for the trauma patient requiring massive transfusion.
