Review Meta AnalysisHow safe is gelatin? A systematic review and meta-analysis of gelatin-containing plasma expanders vs crystalloids and albumin.
Gelatin is a widely used synthetic colloid resuscitation fluid. We undertook a systematic review and meta-analysis of adverse effects in randomized and nonrandomized studies comparing gelatin with crystalloid or albumin for treatment of hypovolemia. Multiple databases were searched systematically without language restrictions until August 2015. ⋯ The mean crystalloid-to-colloid ratio was 1.4. Gelatin solutions increase the risk of anaphylaxis and may be harmful by increasing mortality, renal failure, and bleeding possibly due to extravascular uptake and coagulation impairment. Until well-designed randomized controlled trials show that gelatin is safe, we caution against the use of gelatins because cheaper and safer fluid alternatives are available.

ReviewFluid management in sepsis: The potential beneficial effects of albumin.
Fluid administration is a key intervention in hemodynamic resuscitation. Timely expansion (or restoration) of plasma volume may prevent tissue hypoxia and help to preserve organ function. In septic shock in particular, delaying fluid resuscitation may be associated with mitochondrial dysfunction and may promote inflammation. ⋯ Fluid resuscitation with human albumin is less likely to cause nephrotoxicity than with artificial colloids, and albumin infusion has the potential to preserve renal function in critically ill patients. These properties may be of clinical relevance in circulatory shock, capillary leak, liver cirrhosis, and de-escalation after volume resuscitation. Sepsis is a candidate condition in which human albumin infusion to preserve renal function should be substantiated.

Viewing the intensive care unit (ICU) as a control system with inputs (patients) and outputs (outcomes), we focus on actuation (therapies) of the system and how to enhance our understanding of status of patients and their trajectory in the ICU. To incorporate the results of these analytics meaningfully, we feel that a reassessment of predictive scoring systems and of ways to optimally characterize and display the patient's "state space" to clinicians is important. Advances in sensing (diagnostics) and computation have not yet led to significantly better actuation, and so we focus on ways that data can be used to improve actuation in the ICU, in particular by following therapeutic burden along with disease severity. This article is meant to encourage discussion about how the critical care community can best deal with the data they see each day, and prepare for recommendations that will inevitably arise from application of major federal and state initiatives in big data analytics and precision medicine.

Observational StudyClinical and economic burden of bloodstream infections in critical care patients with central venous catheters.
Bloodstream infections (BSIs) complicate the management of intensive care unit (ICU) patients. We assessed the clinical and economic impact of BSI among patients of a managed care provider group who had a central venous catheter (CVC) placed in the ICU. ⋯ Bloodstream infections after CVC placement in ICU patients are associated with significant increases in costs of care and risk of death during the index hospitalization but no differences in readmissions or costs after discharge.
