Comparative StudyComparison of Positive End-Expiratory Pressure of 8 versus 5 cm H2O on Outcome After Cardiac Operations.
Postoperative positive end-expiratory pressure (PEEP) selection in patients who are mechanically ventilated after cardiac operations often seems random. The aim of this investigation was to compare the 2 most common postoperative initial PEEP settings at our institution, 8 and 5 cm H2O, on postoperative initial tracheal intubation time (primary outcome); cardiovascular intensive care unit (CVICU); hospital length of stay (LOS); occurrence of pneumonia; and hospital mortality (secondary outcomes). ⋯ Patients being mechanically ventilated after cardiac operations with an initial postoperative PEEP setting of 8 versus 5 cm H2O differed significantly only on hospital LOS but the difference was likely clinically unimportant. Thus, use of 8 cm H2O PEEP in these patients without a clinical indication, although likely not harmful, does not seem beneficial.

Integrating Palliative Care into Critical Care: A Quality Improvement Study.
Many terminally ill patients experience an increasing intensity of medical care, an escalation frequently not consistent with their preferences. In 2009, formal palliative care consultation (PCC) was integrated into our medical intensive care unit (ICU). We hypothesized that significant differences in clinical and economic outcomes exist between ICU patients who received PCC and those who did not. ⋯ Patients who received PCC had higher disease acuity, longer ICU lengths of stay, and higher ICU mortality than controls. "Trigger" programs in the ICU may improve utilization of PCC services, improve patient comfort, and reduce invasive, often futile end-of-life care.

ReviewNeurogenic Stunned Myocardium Following Acute Subarachnoid Hemorrhage: Pathophysiology and Practical Considerations.
Neurogenic stunned myocardium (NSM) is a triad of transient left ventricular dysfunction, electrocardiogram changes, and elevation in cardiac enzymes, often mimicking a myocardial infarction. It has been described following acute brain injury. The purported mechanism is catecholamine excess resulting in cardiac dysfunction. ⋯ Basal and mid-ventricular segments of the left ventricle are most commonly involved. NSM poses therapeutic challenges when it occurs secondary to aneurysmal subarachnoid hemorrhage, particularly in the setting of coexisting vasospasm. Overall, NSM carries good prognosis if recognized early, with appropriate management of hemodynamic and cardiopulmonary parameters.

ReviewMaking a Difference in Eye Care of the Critically Ill Patients.
Ocular surface disorders are frequently encountered in patients under sedation and paralyzed patients in intensive care units (ICUs). In the ICUs, treatment is usually focused on the management of organ failures, and eye care becomes a side issue. As a result, ophthalmological complications do occur (incidence ranges from 3.6% to 60%) and are frequently overlooked in this setting. ⋯ We only looked at higher quality articles. Among various eye care measures that have been advocated to prevent exposure keratopathy, the most effective is the application of polyethylene covers. Early diagnosis and effective treatment will help prevent microbial keratitis and visual loss.

Case ReportsPheochromocytoma-Induced Inverted Takotsubo-Like Cardiomyopathy Leading to Cardiogenic Shock Successfully Treated With Extracorporeal Membrane Oxygenation.
Pheochromocytoma classically displays a variety of rather benign symptoms, such as headache, palpitations, and sweating, although severe cardiac manifestations have been described. We report a case of pheochromocytoma-induced inverted takotsubo-like cardiomyopathy leading to shock and cardiac arrest successfully treated with extracorporeal membrane oxygenation (ECMO) as a bridge to pharmacological therapy and curative adrenalectomy. A previously healthy 46-year-old woman presented to the emergency department with abdominal pain, dyspnea, nausea, and vomiting. ⋯ The patient recovered after rehabilitation. We conclude that pheochromocytoma should be considered in patients presenting with unexplained cardiovascular compromise, especially if they display (inverted) takotsubo contractile pattern. Timely, adequate management might involve ECMO as a bridge to pharmacological therapy and curative surgery.
