There is a critical mismatch between available organs for transplant and acutely or critically ill patients with end-stage organ disease. Patients who may benefit from organ transplantation far outnumber available organs. The causes for this imbalance are multiple. ⋯ In addition, physiologic consequences of brain death are correlated with affected body systems and mechanism-based therapies to support organ function pending transplantation. Ethical/legal issues are explored as related to patient autonomy and optimal family outcomes. Effective family communication, astute clinical assessment, and optimal clinical management of the organ donor are illustrated using a case study approach, highlighting the role of the advanced practice nurse in donor management.

Review Case ReportsPrevention of secondary brain injury: targeting technology.
Use of technology in the management of the severely brain-injured patient has increased over the past decade and can be confusing and overwhelming to the critical care nurse clinicians who are new to the field of neurology. This article will describe normal physiology and cerebral dynamics and potential abnormal physiology encountered after brain injury. ⋯ Recognizing the difficult task of trying to control secondary injury in our patients is the first step to better outcomes. Implementing the use of technology to mitigate the situation must be done with careful consideration and a team approach to achieve the greatest benefit for the patient.

Evidence suggests that the mortality and morbidity of acquired brain injury could be reduced if clinicians used an aggressive intracranial pressure guided approach to care. Despite nearly 50 years of evidence that intracranial pressure monitoring benefits patient care, only about half of the patients who could benefit are monitored. ⋯ Others cite cost as the reason. This article discusses the risks and benefits of intracranial pressure monitoring and the current state of evidence of why patients should be monitored.

ReviewThe effect of hypothermia and hyperthermia on acute brain injury.
The brain is extraordinarily susceptible to changes in temperature. Hyperthermia has been shown to exacerbate the biochemical cascade of secondary brain injury. Inversely, hypothermia limits the damaging effects of secondary brain injury. ⋯ This article presents the pathophysiology of secondary brain injury and how it is affected by both hypothermia and hyperthermia. A review of the research leading up to clinical trials is explored, as well as a discussion of the future of temperature modulation for the brain injury patient. This information will help healthcare providers understand the effect that both hypothermia and hyperthermia have on the acutely injured brain.

The goal of palliative care is to provide the alleviation or reduction of suffering and the support for the best possible quality of life for patients regardless of the stage of the disease. Palliative care can be provided in any patient care setting, including intensive care units. ⋯ Other studies suggest that approximately half of all chronically ill patients who die in a hospital receive care in the intensive care unit within 3 days of their deaths. Critical care nurses who work in neurological intensive care units are at the forefront of integrating palliative and critical care.
