ReviewVeno-arterial extracorporeal membrane oxygenation for adult cardiovascular failure.
To examine the utility and technical challenges of applying veno-arterial extracorporeal membrane oxygenation for acute cardiovascular failure in adults with acute and chronic causes of heart failure. ⋯ Veno-arterial extracorporeal membrane oxygenation is an expensive, complex, resource intensive support. It is essential that its future use be guided by evidence obtained from centres that have demonstrated timely, safe support.

This review aims to evaluate the latest versions of the Acute Physiology and Chronic Health Evaluation, Simplified Acute Physiology Score and Mortality Probability Model scores, make comparisons and describe their strengths and limitations. Additionally, we provide critical analysis and recommendations for the use of these scoring systems in different scenarios. ⋯ ICU scoring systems provide a valuable framework to characterize patients' severity of illness for the evaluation of ICU performance, for quality improvement initiatives and for benchmarking purposes. However, to ensure the best accuracy, constant updates as well as regional customizations are required.

Review Historical ArticleA history of outcome prediction in the ICU.
There are few first-hand accounts that describe the history of outcome prediction in critical care. This review summarizes the authors' personal perspectives about the development and evolution of Acute Physiology and Chronic Health Evaluation over the past 35 years. ⋯ There is increasing evidence that superior accuracy in outcome prediction requires complex modeling with detailed adjustment for diagnosis and physiologic abnormalities. Thus, an automated electronic system is recommended for gathering data and generating predictions. Support, either public or private, is required to assist users and to update and improve models. Current outcome prediction models have increasingly focused on benchmarks for resource use, a trend that seems likely to increase in the future.

ReviewFluid removal in acute heart failure: diuretics versus devices.
Fluid removal and relief of congestion are central to treatment of acute heart failure. Diuretics have been the decongestive mainstay but their known limitations have led to the exploration of alternative strategies. This review compares diuretics with ultrafiltration and examines the recent evidence evaluating their use. ⋯ Decongestion remains a major challenge in acute heart failure. Although recent studies provide useful data to guide practice, the relatively poor outcomes point to the continued need to identify better strategies for safe and effective decongestion.

ReviewIs there still a role for low-dose dopamine use in acute heart failure?
Acute heart failure (AHF) is a major health problem worldwide, with no proven therapy. Low-dose dopamine has been used in this entity to improve renal outcomes in the past decades. The aim of this article is to review the former and recent clinical trials about the use of low-dose dopamine in AHF. ⋯ On the basis of the current data, there is no role for the routine use of low-dose dopamine in nonhypotensive patients with AHF. Further studies are needed to define the role of low-dose dopamine in patients with AHF and hypotension. Until the availability of more data, the use of dopamine in AHF should be individualized.
