Long stays in the intensive care unit are associated with high costs and burdens on patients and patients' families and in turn affect society at large. Although factors that affect length of stay and outcomes of care in the intensive care unit have been studied extensively, the conclusions reached have not been reviewed to determine whether they reveal an organizational pattern that might be of practical use in reducing length of stay in the unit. ⋯ Interventions involving palliative care, ethics consultations, and other methods to increase communication between healthcare personnel, patients, and patients' families may be helpful in decreasing length of stay in the intensive care unit. Further studies are needed to provide a strategy for targeting specific risk factors indicated by the literature review.

Multicenter Study
Practice of expert critical care nurses in situations of prognostic conflict at the end of life.
Prolonging the living-dying process with inappropriate treatment is a profoundly disturbing ethical issue for nurses in many practice areas, including the intensive care unit. Despite the frequent occurrence of such distressing events, research suggests that critical care nurses assume a limited role in end-of-life decision making and care planning. ⋯ The transition from curative to end-of-life care in the intensive care unit is often fraught with ambiguity and anguish. The expert nurses demonstrated the ability and willingness to actively protect and advocate for their vulnerable patients even in situations in which the nurses' actions did not influence the outcomes.

Acute neurogenic pulmonary edema, a common and underdiagnosed clinical entity, can occur after virtually any form of injury of the central nervous system and is a potential early contributor to pulmonary dysfunction in patients with head injuries. ⋯ All patients who had neurogenic pulmonary edema due to traumatic head injury had myocardial dysfunction. The mechanisms of the dysfunction were multiple. The great improvement in wall motion seen in 2 patients indicated the presence of a stunned myocardium. Further studies are needed to understand the mechanisms of this cardiac dysfunction.

Review Meta Analysis
Mechanical thromboprophylaxis in critically ill patients: a systematic review and meta-analysis.
To systematically review the randomized trials, observational studies, and survey evidence on compression and pneumatic devices for thromboprophylaxis in intensive care patients. ⋯ The limited evidence suggests that use of compressive and pneumatic devices yields results not significantly different from results obtained with no treatment or use of low-molecular-weight heparin. Until large randomized controlled trials are conducted, the role of mechanical approaches to thromboprophylaxis for intensive care patients remains uncertain.
