Review Meta Analysis
Indications and management of mechanical fluid removal in critical illness.
The Acute Dialysis Quality Initiative (ADQI) dedicated its Twelfth Consensus Conference (2013) to all aspects of fluid therapy, including the management of fluid overload (FO). The aim of the working subgroup 'Mechanical fluid removal' was to review the indications, prescription, and management of mechanical fluid removal within the broad context of fluid management of critically ill patients. ⋯ Mechanical fluid removal should be considered as a therapy for FO, but more research is necessary to determine its exact role and clinical application.

I. V. fluid therapy plays a fundamental role in the management of hospitalized patients. While the correct use of i.v. fluids can be lifesaving, recent literature demonstrates that fluid therapy is not without risks. ⋯ In this article, we review a recently proposed model for fluid therapy in severe sepsis and propose a framework by which it could be adopted for use in most situations where fluid management is required. Considering the dose-effect relationship and side-effects of fluids, fluid therapy should be regarded similar to other drug therapy with specific indications and tailored recommendations for the type and dose of fluid. By emphasizing the necessity to individualize fluid therapy, we hope to reduce the risk to our patients and improve their outcome.

Fluid management during critical illness is a dynamic process that may be conceptualized as occurring in four phases: rescue, optimization, stabilization, and de-escalation (mobilization). The selection and administration of resuscitation fluids is one component of this complex physiological sequence directed at restoring depleted intravascular volume. Presently, the selection of i.v. fluid is usually dictated more by local practice patterns than by evidence. ⋯ There is no evidence to support the use of other colloids. The use of balanced salt solutions in preference to 0.9% saline is supported by the absence of harm in large observational studies. However, there is no compelling randomized trial-based evidence demonstrating improved clinical outcomes with the use of balanced salt solutions compared with 0.9% saline at this time.

Awareness occurred in 1 in 19,000 general anaesthetics, resulting in distress in 51% of cases and longterm harm in 41%. BIS monitoring was used in 5% of cases of awareness.

Summary Current guidelines recommend the administration of hormonal combination therapy including immunosuppressive doses of corticosteroids to donors with low left ventricular ejection fractions and to consider hormonal therapy administration to all donors. However, these recommendations are largely based on observational data. The aim of this systematic review (SR) was to assess the clinical efficacy and safety of corticosteroids in brain-dead potential organ donors. ⋯ Overall quality of included studies was poor, as most of them presented high risks of confounding. This SR highlights the low quality and conflicting evidence supporting the routine use of corticosteroids in the management of organ donors. A large trial evaluating the effect of corticosteroids on outcomes such as organ recovery and graft survival is warranted.
