This paper reviews published data on welfare aspects of stag restraint and velvet antler removal, and prevention of antler growth. Several studies of physical restraint and handling demonstrate behavioural and physiological changes both during and after velvet antler removal. Interpretations vary as to whether the act of velvet antler removal imposes a welfare cost additional to that of handling and restraint alone. ⋯ Post-operative sequelae are uncommon, but include clostridial infection. Antler growth in most stags can be prevented by rubber-band application to the growing pedicle, although behavioural changes after ring application suggest this practice may be painful. The procedures used for velvet antler removal, and whether practices are acceptable on the balance of welfare costs and benefits, should be reviewed on an ongoing basis as science, using an increasing range of techniques and measures, provides more data about the welfare implications of this practice.

Neurotoxicity manifesting as convulsions is a recognised complication of the administration of local anaesthetic drugs as part of a regional anaesthetic technique. We describe a case of self-limiting convulsions following the institution of an axillary brachial plexus block with levobupivacaine. Although the occurrence of convulsions following the administration of racemic bupivacaine is a well-recognised complication, there have been no clinical case reports published describing convulsions following the use of levobupivacaine in regional anaesthesia.

[Posterior block of lumbar plexus for postoperative analgesia after hip arthroplasty].
To describe early postoperative analgesic quality from a posterior lumbar plexus block in the psoas compartment, located by neurostimulation. We used a single paramedial puncture at L4, following Chayen's approach, in patients undergoing uncemented hip arthroplasty under subarachnoid anesthesia with 0.5% bupivacaine. ⋯ A posterior lumbar plexus block using a single shot gives effective analgesia in the first 12 hours after surgery performed with spinal anesthesia. Continuous infusion through a catheter may provide better analgesia than that observed in this study.
