A basic understanding of metabolic alterations that occur following neurotrauma is essential for addressing nutritional requirements. Interventions must be research based and must focus on the support of metabolic alterations, minimizing the effect of catabolism and optimizing caloric delivery to meet metabolic demand. ⋯ Nutritional support requires an ongoing, daily assessment of caloric goals, protein requirements, patient responses, and assessment of nutritional laboratory values. Using this strategy, neurotrauma patients will have the greatest opportunity for a positive outcome.

ReviewKeeping the brain in the zone. Applying the severe head injury guidelines to practice.
Providing care to the TBI patient population with severe injuries requires an integrated multidisciplinary approach. The team in clinical practice must be willing to examine its own practice, seek out the latest information on TBI, and critically analyze the information. Members must be open to changing their own practice when the data presented support change. ⋯ The standardization of these interventions into protocols facilitates team communication and coordination. Measuring outcomes is imperative for evaluating the effectiveness of current treatment algorithms. Changes in treatment practice should be based on the measured outcomes and advances in the scientific literature.

Critical care nurses are essential team members during the process of determining brain death and preparing for organ donation. Using their knowledge of the criteria for brain death, they care for the dying patient, support the grieving family, and participate in the consent process for organ donation. Nurses make a critical difference in saving the lives of others through the gift of life.

ReviewMicrosensor and microdialysis technology. Advanced techniques in the management of severe head injury.
Neuroscientists continue the search for the "magic bullet" that will prevent the deleterious effects of primary and secondary brain injury. Indirect measurement of the effects of primary and secondary brain injury through the study of ICP- or CPP-directed management, CBF monitoring, Sjo2 monitoring, and TCD monitoring has led to improved care of persons with brain injury. Although the findings from brain injury research using microsensor and microdialysis technology are only preliminary and extensive research is still needed, these technologies have dramatically expanded knowledge about brain injury at the cellular level. ⋯ Nurses must obtain a comprehensive knowledge base of brain injury pathophysiology and how extended neuromonitoring can lead to improved outcomes. Technical proficiency will also be important to ensure that treatment and research conclusions are based on accurate data. Finally and perhaps most importantly, it will be critical for nurses to participate in and develop research studies that explore the impact of interventions, especially nursing care activities, on the injured brain if these exciting new advances are to be translated into tangible benefits for brain-injured patients.

ReviewIntracranial pressure monitoring and assessing intracranial compliance in brain injury.
Caring for the patient with a brain injury is a dynamic process with the goal of providing therapy to prevent secondary injury. Until practitioners have a better understanding of the pathophysiology of ischemia and the response of therapies for treating increased ICP, they must use the tools that exist. ICP monitoring gives a rough index of the relationships and the response of the intracranial contents to changes in volume that may produce increases in pressure and further damage. Understanding the information supplied by ICP monitoring is imperative to successful management of increased ICP.
