ReviewThe modern cardiovascular care unit: the cardiologist managing multiorgan dysfunction.
Despite many advances in the management of critically ill patients, cardiogenic shock remains a challenge because it is associated with high mortality. Even if there is no universally accepted definition of cardiogenic shock, end-perfusion organ dysfunction is an obligatory and major criterion of its definition.Organ dysfunction is an indicator that cardiogenic shock is already at an advanced stage and is undergoing a rapid self-aggravating evolution. The aim of the review is to highlight the importance to diagnose and to manage the organ dysfunction occurring in the cardiogenic shock patients by providing the best literature published this year. ⋯ In this review, we aimed to highlight for intensivists and cardiologists managing cardiogenic shock, the recent advances in the care of end-organ dysfunctions associated with cardiogenic shock. The management of organ dysfunction is based on the improvement of the cardiac function by etiologic therapy, inotropes and assist devices but will often necessitate organ supports in hospitals with the right level of equipment and multidisciplinary expertise.

There has been a recent shift in the focus of providing nutrition support to critically ill adults towards enhancing recovery and promoting survivorship. With this has come an evaluation of our current approaches to nutrition support, which includes whether continuous feeding is optimal, particularly for reducing muscle wasting, but also for managing blood glucose levels and feeding intolerance and at the organizational level. This review will discuss the pros and cons of using intermittent and continuous feeding relating to several aspects of the management of critically ill adults. ⋯ Although there are limited studies investigating the safety and efficacy of an intermittent rather than continuous feeding regimen in critically ill adults, there are several theoretical advantages. Further studies should investigate these and in the meantime, feeding regimens should be devised based on individual patient factors.

Hypovitaminosis C and vitamin C deficiency are very common in critically ill patients due to increased needs and decreased intake. Because vitamin C has pleiotropic functions, deficiency can aggravate the severity of illness and hamper recovery. ⋯ A short course of intravenous vitamin C in pharmacological dose seems a promising, well tolerated, and cheap adjuvant therapy to modulate the overwhelming oxidative stress in severe sepsis, trauma, and reperfusion after ischemia. Large randomized controlled trials are necessary to provide more evidence before wide-scale implementation can be recommended.

ReviewCritical care echocardiography and outcomes in the critically ill.
Critical care echocardiography offers a comprehensive assessment of cardiac anatomy and function performed by the intensivist at point of care. This has resulted in widespread use of critical care echocardiography in ICUs leading to the question if this increased usage has resulted in improved patient outcomes. ⋯ Recent studies have evaluated the role of critical care echocardiography in the ICU with an emphasis on establishing accurate diagnosis and measurement of haemodynamic variables. There are no prospective randomized controlled trials that have examined the effect of critical care echocardiography on patient outcomes SUMMARY: Although the effect of critical care echocardiography on patient outcomes has not yet been established, its value as a diagnostic tool has been well demonstrated. We can only assume that its diagnostic capability leads to an improvement in patient outcomes.
