SummaryWe analysed 366 claims related to regional anaesthesia and analgesia from the 841 anaesthesia . Non-obstetric claims were more likely to relate to severe outcomes than obstetric ones. The maximum values of claims were higher for claims related to neuraxial blocks and eye blocks than for peripheral nerve blocks. Despite many limitations, including lack of clinical detail for each case, the dataset provides a useful overview of the extent, patterns and cost associated with the claims.

Although lidocaine iontophoresis is effective more quickly than the eutectic mixture of local anaesthetic cream, the superior quality of analgesia produced by the eutectic mixture in this study should be borne in mind if these treatments are used electively.

SummaryThe performance of the occlusion and Pethick tests in detecting faulty inner tubes in co-axial circle and Bain systems was compared. Twelve co-axial circle and 12 Bain anaesthetic breathing systems were tested using the occlusion and the Pethick tests. For each system, three tubes were intact, and the remaining nine had a defect deliberately created in the inner tube (three proximal, three middle and three distal). The investigators were blinded to which of the tubes were defective, and to each other's results. The results showed 100% specificity for both tests. The sensitivity of the occlusion test for detecting faulty breathing systems was found to be good (98%). Our results suggest that the occlusion test should be performed in preference to the Pethick test when testing co-axial circle and Bain systems.
