Long-term survival of adults with cardiogenic shock after venoarterial extracorporeal membrane oxygenation.
This study was designed to examine the long-term survival of patients who survived to be weaned from venoarterial extracorporeal membrane oxygenation (VA ECMO) and to determine which factors present at initiation and during ECMO predict long-term survival. We further sought to develop the preliminary long-term outcome after VA ECMO score that would predict patient outcome and to assess its accuracy at various time points. ⋯ Good long-term survival can be achieved in patients who have been successfully weaned from VA-ECMO. The factors present at initiation and during ECMO can relate to altered risk of long-term survival.

Symptom burden and health-related quality of life among intensive care unit survivors in Argentina: A prospective cohort study.
Our goal was to describe the evolution of selected physical and psychologic symptoms and identify the determinants of health-related quality of life (HRQOL) after intensive care unit (ICU) discharge. ⋯ Determinants of HRQOL after ICU discharge were both related to late sequelae of critical illness and to some events occurring in the ICU. Notwithstanding the high symptom burden, patients still perceived their HRQOL as good.

ReviewIntravenous immunoglobulin in critically ill adults: When and what is the evidence?
Intravenous immunoglobulin (IVIg) use is growing dramatically internationally due to the increasing numbers of acute and chronic conditions that may benefit from IVIg. Patients with conditions that may benefit from IVIg might require intensive care unit (ICU) admission, supporting the need to review IVIg use in the critical care setting. The most common clinical indications for IVIg in adults that may require ICU admission and are commonly supported under clinical practice guidelines are Guillain-Barré syndrome, myasthenia gravis and Lambert-Eaton myasthenic syndrome, inflammatory myopathies, and primary or secondary immunodeficiency diseases complicated by severe bacterial sepsis. ⋯ The evidence for IVIg use in sepsis and septic shock remains controversial and insufficient to recommend its routine use. Intravenous immunoglobulin is expensive and also carries risks of adverse effects, including common and benign infusion-related reactions, as well as relatively rare and more serious problems, such as thromboembolic events, renal failure, and aseptic meningitis. In this article, we review the literature on conditions requiring ICU admission and IVIg, and we classify them as supported, emerging, or unsupported indications based on the available evidence and guidelines for clinical use of IVIg.

Review Meta AnalysisDoppler-based renal resistive index for prediction of renal dysfunction reversibility: A systematic review and meta-analysis.
Doppler-based renal resistive index (RI) might help in distinguishing transient from persistent acute kidney injury (AKI). The main objective of these systematic review and meta-analysis was to investigate the diagnostic performance of RI in predicting short-term reversibility of AKI. ⋯ These results suggest that an elevated RI may be a predictor of persistent AKI in critically ill patients. Further studies are warranted, however, to clarify the exact test performance given the marked heterogeneity among the included studies.

Functional brain imaging in survivors of critical illness: A prospective feasibility study and exploration of the association between delirium and brain activation patterns.
We undertook this pilot prospective cohort investigation to examine the feasibility of functional magnetic resonance imaging (fMRI) assessments in survivors of critical illness and to analyze potential associations between delirium and brain activation patterns observed during a working memory task (N-back) at hospital discharge and 3-month follow-up. ⋯ Our data support the feasibility of using fMRI in survivors of critical illness at 3-month follow-up but not at discharge. In this small study, delirium was not associated with distinct or abnormal brain activation patterns, although overall performance on a cognitive task of working memory was poorer than observed in other cohorts of individuals with medically related executive dysfunction, mild cognitive impairment, and mild traumatic brain injury.
