Review Meta AnalysisThe efficacy of propofol on emergence agitation - a meta-analysis of randomized controlled trials.
Emergence agitation (EA) is a common, post-anesthetic complication in pediatric patients following sevoflurane and desflurane anesthesia. The aim of this meta-analysis was to assess the effects of an adjunctive dose of propofol to reduce the incidence of EA in pediatric patients. ⋯ Future studies on the benefits of adjunct propofol in reducing the incidence of EA are required.

ReviewEnhanced Recovery After Surgery (ERAS) for gastrointestinal surgery, part 1: pathophysiological considerations.
The present article has been written to convey concepts of anaesthetic care within the context of an Enhanced Recovery After Surgery (ERAS) programme, thus aligning the practice of anaesthesia with the care delivered by the surgical team before, during and after surgery. ⋯ Evidence-based strategies aimed at controlling the disruption of homoeostasis need to be evaluated in the context of ERAS programmes. Anaesthesiologists could, therefore, play a crucial role in facilitating the recovery process.

ReviewMicrocirculatory dysfunction and tissue oxygenation in critical illness.
Severe sepsis is defined by organ failure, often of the kidneys, heart, and brain. It has been proposed that inadequate delivery of oxygen, or insufficient extraction of oxygen in tissue, may explain organ failure. Despite adequate maintenance of systemic oxygen delivery in septic patients, their morbidity and mortality remain high. ⋯ We review how capillary flow patterns affect oxygen extraction efficacy in tissue, and how the regulation of tissue blood flow must be adjusted to meet the metabolic needs of the tissue as capillary flows become disturbed as observed in critical illness. Using the brain, heart, and kidney as examples, we discuss whether disturbed capillary flow patterns might explain the apparent mismatch between organ blood flow and organ function in sepsis. Finally, we discuss diagnostic means of detecting capillary flow disturbance in animal models and in critically ill patients, and address therapeutic strategies that might improve tissue oxygenation by modifying capillary flow patterns.
