Autonomic Impairment in Severe Traumatic Brain Injury: A Multimodal Neuromonitoring Study.
Autonomic impairment after acute traumatic brain injury has been associated independently with both increased morbidity and mortality. Links between autonomic impairment and increased intracranial pressure or impaired cerebral autoregulation have been described as well. However, relationships between autonomic impairment, intracranial pressure, impaired cerebral autoregulation, and outcome remain poorly explored. Using continuous measurements of heart rate variability and baroreflex sensitivity we aimed to test whether autonomic markers are associated with functional outcome and mortality independently of intracranial variables. Further, we aimed to evaluate the relationships between autonomic functions, intracranial pressure, and cerebral autoregulation. ⋯ Autonomic impairment, as measured by heart rate variability and baroreflex sensitivity, is significantly associated with increased mortality after traumatic brain injury. These effects, though partially interlinked, seem to be independent of age, trauma severity, intracranial pressure, or autoregulatory status, and thus represent a discrete phenomenon in the pathophysiology of traumatic brain injury. Continuous measurements of heart rate variability and baroreflex sensitivity in the neuromonitoring setting of severe traumatic brain injury may carry novel pathophysiological and predictive information.

Outcomes of Protocol-Driven Care of Critically Ill Severely Anemic Patients for Whom Blood Transfusion Is Not an Option.
To compare the outcomes of severely anemic critically ill patients for whom transfusion is not an option ("bloodless" patients) with transfused patients. ⋯ Overall risk of mortality in severely anemic critically ill bloodless patients appeared to be comparable with transfused patients, albeit the latter group had older age and higher Acute Physiology and Chronic Health Evaluation II score. Use of a protocol to manage anemia in these patients in a center with established patient blood management and bloodless medicine and surgery programs is feasible and likely to contribute to improved outcome, whereas more studies are needed to better delineate the impact of such programs.

Growing Up After Critical Illness: Verbal, Visual-Spatial, and Working Memory Problems in Neonatal Extracorporeal Membrane Oxygenation Survivors.
To assess neuropsychologic outcome in 17- and 18-year-old neonatal extracorporeal membrane oxygenation survivors. ⋯ Adolescents treated with neonatal extracorporeal membrane oxygenation are at risk of verbal, visual-spatial, and working memory problems. Future research should focus on 1) the longitudinal outcome of specific neuropsychologic skills in adolescence and adulthood; 2) identifying risk factors of neuropsychologic dysfunction; 3) evaluating to what extent "severity of illness" is responsible for acquired brain injury; and 4) effects of timely cognitive rehabilitation.

Randomized Controlled TrialImpact of Proactive Nurse Participation in ICU Family Conferences: A Mixed-Method Study.
To investigate family perceptions of having a nurse participating in family conferences and to assess the psychologic well being of the same families after ICU discharge. ⋯ Families valued the conferences themselves and valued the proactive participation of a nurse. These positive perceptions were associated with significant anxiety or depression subscale scores but not with changes in posttraumatic stress-related symptoms.
