ReviewPsychiatric aspects of organ transplantation in critical care.
Intensive care unit teams are a critical part of the solid organ transplant process. The psychosocial issues involved during critical periods of transplantation are important for intensive care physicians and clinicians to understand to provide comprehensive care to transplant patients. ⋯ Considered are the pretransplant evaluation phase, psychiatric disorders in transplant patients, and cognitive impairments and delirium with additional issues specific to particular organs. Also covered are the side effects of immunosuppressive medications and special issues arising with living donors.

ReviewNeurobehavioral management of traumatic brain injury in the critical care setting.
Traumatic brain injury (TBI) results in approximately 230,000 hospitalizations annually in the United States. Advances in the acute management of TBI have improved survival after TBI. Many TBI survivors develop neurobehavioral disturbances in the acute post-injury period. ⋯ This article defines and describes TBI and reviews its common neuroanatomic and neurobehavioral consequences. These disturbances are organized under the framework of posttraumatic encephalopathy, and the characteristic forms and stages of recovery of this condition are discussed. Recommendations regarding evaluation and management of posttraumatic neurobehavioral problems in the critical care setting are offered.

ReviewDelirium in the acute care setting: characteristics, diagnosis and treatment.
Delirium is a neurobehavioral syndrome caused by the transient disruption of normal neuronal activity secondary to systemic disturbances. It is also the most common psychiatric syndrome found in the general hospital setting, its prevalence surpassing better known psychiatric disorders. This article reviews the published literature on delirium and addresses the epidemiology, known etiologic factors, presentation and characteristics of delirium, while emphasizing what is known about treatment strategies and prevention. Given increasing evidence that delirium is not always reversible and the many sequelae associated with its development, physicians must do everything possible to prevent its occurrence or shorten its duration, by recognizing its symptoms early, correcting underlying contributing causes, and using treatment strategies proven to help recover functional status.

Posttraumatic stress disorder (PTSD) is a common psychiatric condition that can occur after a traumatic event. Individuals exposed to traumatic events are at risk for PTSD and other psychologic morbidity, such as depression, panic disorder, generalized anxiety disorder, and substance abuse. ⋯ Emerging literature suggests a significantly increased risk for symptoms of PTSD among survivors of critical illness and the families of patients who survive or die after critical illness. This review summarizes these studies and provides suggestions for current clinical implications and for future research.

ReviewDetection and management of pre-existing cognitive impairment and associated behavioral symptoms in the Intensive Care Unit.
Recent increase in both the elderly population and associated incidence of dementia are of critical importance to patient care in ICUs in the United States. Identification of pre-existing cognitive impairment, such as mild cognitive impairment and dementia, could prevent delirium and associated morbidity and mortality in the ICU. Additionally, noncognitive behavioral symptoms, such as depression, psychosis, agitation, and catastrophic reactions, are common in patients with pre-existing cognitive impairment. Detection and management of noncognitive behavioral symptoms associated with MRI and dementia in ICU leads to improved delivery of life-saving critical care.
