ReviewCopper removal strategies for Wilson's disease crisis in the ICU.
Wilson's disease is a rare, inherited, autosomal recessive disorder of copper metabolism which leads to an accumulation of copper in body tissues. If a patient develops a Wilson's crisis, mortality can approach 100%. The treatment of such patients is mostly organ support but a possible treatment goal is to try to rapidly remove copper from their system. ⋯ We found 11 case reports where therapeutic plasma exchange was used and six case reports where various forms of albumin dialysis were used as techniques for rapidly reducing serum copper levels. To date, the case reports are encouraging that therapeutic plasma exchange and albumin dialysis can either delay or prevent the need for liver transplantation in patients with fulminant hepatic failure due to Wilson's disease. However, these case reports are mainly in the paediatric or young adult population, thus further studies in adults are warranted.

ReviewPreventing cerebral oedema in acute liver failure: the case for quadruple-H therapy.
Severe cerebral oedema is a life-threatening complication of acute liver failure. Hyperammonaemia and cerebral hyperaemia are major contributing factors. A multimodal approach, which incorporates hyperventilation, haemodiafiltration, hypernatraemia and hypothermia (quadruple-H therapy), may prevent or attenuate severe cerebral oedema. ⋯ The administration of concentrated saline increases serum tonicity and further reduces cerebral swelling. In addition, the pathologically increased cerebral blood-flow is further attenuated by therapeutic hypothermia. The combination of all four treatments in a multimodal approach may be a safe and effective means of attenuating or treating the cerebral oedema of acute liver failure and preventing death from neurological complications.

ReviewVeterinary and human anaesthesia: an overview of some parallels and contrasts.
The history of human and veterinary anaesthesia is both intertwined and parallel. Physicians and anaesthetists often first experimented on animals and developments from human anaesthesia have been incorporated into veterinary medicine. Within veterinary medicine, anaesthesia is a specialty discipline as it is in human medicine. ⋯ Furthermore, some agents, particularly alpha-2 adrenoreceptor agonists and ketamine, are used very widely in veterinary practice. Also in contrast to most human anaesthesia, in large animal and exotic animal practice the patients can present a physical danger to the anaesthetist. The most notable contrast between human and veterinary anaesthesia is in the reported perioperative complication and mortality rates, with a species dependent perianaesthetic mortality of up to 2% in dogs, cats and horses and greater than 2% in guinea pigs and birds, which is up to 100-fold higher than in human anaesthesia.

ReviewAcute respiratory distress syndrome: current concepts and future directions.
Acute respiratory distress syndrome is one of the leading causes of death in critically ill patients. Recent advances in supportive care have led to a moderate improvement in mortality. ⋯ Though improvements in supportive care may have provided some benefit, there remains an absence of effective biological agents that are necessary to achieve further incremental reduction in mortality. This article will review the evidence available for current treatment strategies and discuss future research directions that may eventually improve outcomes in this important global disease.

Review Meta Analysis Comparative StudyHigh volume local infiltration analgesia compared to peripheral nerve block for hip and knee arthroplasty-what is the evidence?
Since being reported in 2008, high volume local infiltration analgesia (HVLIA) has rapidly gained popularity for patients undergoing hip and knee replacement. We undertook this review to investigate whether there was evidence for equivalence of HVLIA compared to peripheral nerve block techniques with respect to early postoperative analgesia and functional recovery, or for other outcomes such as cost and process efficiency, persistent postsurgical pain and arthroplasty revision rate. ⋯ Nor is it possible to state whether HVLIA provides benefits in terms of persistent postsurgical pain or cost and process efficiency. Well designed trials directly comparing peripheral nerve block with a standardised HVLIA technique are urgently required.
