ReviewOverview of the introduction of neuromuscular monitoring to clinical anaesthesia.
Muscle relaxants were introduced into clinical practice in the early 1940s. From 1949, assessments were being made of the efficacy of various agents in awake volunteers, usually the researchers themselves. From the early to mid 1950s, while interest in using muscle relaxants was keen, concern emerged in the surgical literature that there was a higher mortality rate seen in patients receiving muscle relaxants. ⋯ These were measured responses to single twitch stimulus or tetanic stimulation. In 1970, train-of-four ratio was introduced, then in 1981 post-tetanic count, and in 1989 double burst stimulation. This article reviews the introduction of these techniques.

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.

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.
