Multicenter Study
Major complications of central neuraxial block: report on the Third National Audit Project of the Royal College of Anaesthetists.
Serious complications of central neuraxial block (CNB) are rare. Limited information on their incidence and impact impedes clinical decision-making and patient consent. The Royal College of Anaesthetists Third National Audit Project was designed to inform this situation. ⋯ The data are reassuring and suggest that CNB has a low incidence of major complications, many of which resolve within 6 months.

Review Meta Analysis
Antifibrinolytics in cardiac surgical patients receiving aspirin: a systematic review and meta-analysis.
While conventional practice is to discontinue aspirin prior to elective cardiac surgery there is evidence that its continuation may be associated with improved perioperative outcomes. However, uncertainty exists regarding the efficacy of antifibrinolytic agents in the presence of aspirin. We performed a systematic review and meta-analysis of the literature to address the question of the effects of antifibrinolytic agents in cardiac surgery patients maintained on aspirin in terms of both efficacy and adverse events. ⋯ Antifibrinolytic agents are effective for reducing both chest-tube drainage and transfusion requirements in cardiac surgical patients receiving aspirin. We found no difference between antifibrinolytic and placebo in terms of adverse events but the population was predominantly low-risk. Further studies are required to determine the optimal balance between antiplatelet and antifibrinolytic effects in cardiac surgery.

Prediction of movement responses to noxious stimuli during anaesthesia is of clinical importance. Susceptibility of a parameter of immobility to both hypnotic and analgesic influences could pose an advantage. Here, nociceptive reflexes might be useful, but data regarding the suppression by hypnotic substances are scarce. Therefore, we compared the prediction of movement responses by the RIII reflex threshold and the bispectral index (BIS) during propofol mono-anaesthesia. ⋯ Movement responses to noxious stimuli under propofol can be predicted by the RIII threshold with a comparable accuracy as the BIS. Therefore, the RIII threshold seems to be influenced by hypnotic effects. Since susceptibility of the RIII threshold to analgesic influences is well established, an advantage for the RIII threshold in the prediction of motor responses could be expected when analgesic substances are used in addition to propofol.

Randomized Controlled Trial Comparative Study
Plain articaine or prilocaine for spinal anaesthesia in day-case knee arthroscopy: a double-blind randomized trial.
Both prilocaine and articaine are short-acting local anaesthetics suited for spinal anaesthesia for day-case knee arthroscopy. Articaine is thought to have a faster onset and shorter duration of action than prilocaine, although no comparative study has been published in the anaesthetic literature. ⋯ Spinal anaesthesia with plain articaine 50 mg resulted in a faster recovery of motor function and earlier spontaneous voiding compared with plain prilocaine 50 mg. Surgical anaesthesia was not different. The incidence of TNS was low.

Randomized Controlled Trial Comparative Study
Comparative study of topical anaesthesia with lidocaine 2% vs levobupivacaine 0.75% in cataract surgery.
This study compared the efficacy of topical anaesthesia with levobupivacaine 0.75% vs lidocaine 2% during cataract surgery by phacoemulsification. ⋯ Topical anaesthesia with levobupivacaine 0.75% was more effective than lidocaine 2% in preventing pain and improving patient and surgeon comfort during cataract surgery, with similar toxicity.
