ReviewA Review of the Perceptions of Healthcare Providers and Family Members Toward Family Involvement in Active Adult Patient Care in the ICU.
The objective of this article is to provide a summary of the perceptions of healthcare providers and family members toward their role in active patient care in the ICU and compare the views of healthcare providers with those of relatives of critically ill patients. ⋯ A positive attitude exists among both family members and providers toward the involvement of family members in active care tasks. Providers and family members share the attitude that a partnership is necessary and that encouragement for family members to participate is essential. The findings in this review support the need for more objective research regarding how families are caring for their loved ones and how family involvement in care is affecting patient and family outcomes.

Case ReportsEchography of the Portal Vein in a Patient With Shock.
To report the utility of abdominal ultrasonography to identify portal venous gas in patients with shock, as an indicator of acute mesenteric ischemia, and to illustrate the aspect of portal venous gas on ultrasonography. ⋯ Intensive care physicians should be aware of the ultrasound characteristics of portal venous gas. In patients with shock, in addition to cardiac and thoracic echography, investigation of portal venous gas using bedside ultrasonography may help the clinician to identify patients in whom acute mesenteric ischemia develops.

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.

How Long Does (S)He Have? Retrospective Analysis of Outcomes After Palliative Extubation in Elderly, Chronically Critically Ill Patients.
For chronically critically ill elderly patients on mechanical ventilation, prognosis for significant recovery may be minimal. These individuals, or their surrogates, may decide for "palliative extubation." A common prognostic question arises: "How long does she/he have?" This study describes demographics, mortality, time to death, and factors associated with death after palliative extubation. ⋯ Palliative extubation at end of life was an option selected by an ethnically diverse elderly population. Approximately three-fourths of subjects died in hospital, and one-fourth was discharged alive. Over 50% who died did so within 24 hours, making this useful information for counseling and anticipatory planning. Subjects with systolic blood pressure less than 90 and Charlson Comorbidity Index that is very low or very high had higher mortality.

Observational StudyEpidemiology of Acute Respiratory Distress Syndrome Following Hematopoietic Stem Cell Transplantation.
Pulmonary complications are common following hematopoietic stem cell transplantation. Numerous idiopathic post-transplantation pulmonary syndromes have been described. Patients at the severe end of this spectrum may present with hypoxemic respiratory failure and pulmonary infiltrates, meeting criteria for acute respiratory distress syndrome. The incidence and outcomes of acute respiratory distress syndrome in this setting are poorly characterized. ⋯ Acute respiratory distress syndrome is a frequent complication following hematopoietic stem cell transplantation, dramatically influencing patient-important outcomes. Most cases of acute respiratory distress syndrome following hematopoietic stem cell transplantation do not meet criteria for a more specific post-transplantation pulmonary syndrome. These findings highlight the need to better understand the risk factors underlying acute respiratory distress syndrome in this population, thereby facilitating the development of effective prevention strategies.
