Current opinion in critical care

Nutritional supplementation is paramount to the care of severely injured patients. Despite its widespread use in trauma, many areas of clinical nutrition remain controversial and not well defined. The benefit of early enteral nutrition in the care of injured patients has been well established, with further benefit derived by the administration of immune-enhancing formulas supplemented with glutamine, arginine, nucleotides, and omega-3-fatty acids. A new paradigm of pharmaconutrition has been developed that separates the administration of immunomodulatory nutrients from that of nutritional support. The optimal utilization and benefit of pharmaconutrients, however, remains unclear, as does the need for full caloric provision in the early postinjury phase. ⋯ Building upon previous well performed studies in trauma patients, the current focus of nutritional investigations center on the use of pharmaconutrients to modulate the inflammatory response and the use of hypocaloric feeds. These practices will be reviewed and evidence presented for their use in critically ill and injured patients.

ReviewPhysiological basis for the use of erythropoietin in critically ill patients at risk for acute kidney injury.
Acute kidney injury (AKI) frequently occurs in critically ill patients and is an independent risk factor for poor outcome. The prevention of kidney injury in intensive care remains a great challenge as specific nephroprotective therapies are still lacking. The present review summarizes recent evidence for the use of erythropoietin as a promising candidate to provide protection from AKI. ⋯ Animal studies revealed a physiological basis for the use of erythropoietin in AKI, which may be clinically applicable to prevent AKI in critically ill patients, but clinical studies are still lacking.

ReviewThe timing of spinal stabilization in polytrauma and in patients with spinal cord injury.
Despite improved care of multiple injured patients, controversial data about the best time point for decompression and stabilization of spine fractures and spinal cord injuries are published. Some studies even question the value of surgical management. ⋯ Most studies support the hypothesis that early decompression and stabilization of spine injuries is beneficial in terms of reducing length of stay at the ICU, as well as improving neurological and overall outcome. Good prospective clinical trials are still missing, thus the level of evidence remains low.

ReviewPostinjury immune monitoring: can multiple organ failure be predicted?
Multiple organ failure is the main cause of late morbidity and mortality after severe injury. This disease state is driven by a dysfunctional immune system. Prediction of multiple organ failure on the basis of clinical parameters appears to be insufficient. A better understanding of immunological pathogenesis underlying multiple organ failure may lead to better prediction and innovation in treatment strategy in order to increase the survival of trauma patients. ⋯ General markers of inflammation including cytokines are correlated with posttraumatic complications with a low sensitivity and specificity and are, therefore, of little use as prognostic markers. Current findings regarding the functionality of immune cells are promising and might be of prognostic value in the near future.
