Review Case Reports
Convulsions after ropivacaine 300 mg for brachial plexus block.
A healthy 18-yr-old male (weight 60 kg, height 167 cm), with a history of febrile convulsions in childhood, developed a grand mal convulsion 10 min after the second of two injections of ropivacaine 150 mg, both given incrementally 15 min apart (total 300 mg), for combined axillary/interscalene brachial plexus block. Treatment was with oxygen, lung ventilation, and i.v. midazolam, and the patient made a complete recovery. ⋯ Whether sub-clinical EEG changes identified after operation were related to this sensitivity cannot be determined, but review illustrates wide variation in both the dose and the plasma concentration of local anaesthetics associated with systemic toxicity. The UK recommended dose of ropivacaine for brachial plexus block is 225-300 mg according to stature.

Review Meta Analysis
Psoas compartment block for lower extremity surgery: a meta-analysis.
Psoas compartment block (PCB) is a potentially useful but controversial technique for lower limb surgery. We have conducted a systematic review of the efficacy and safety of PCB for anaesthesia and postoperative analgesia for hip and knee surgery. Relevant studies were identified within PubMed, EMBASE, and the Cochrane Library. ⋯ Although PCB combined with sciatic nerve block and sedation is an effective technique for minor knee surgery, there is currently insufficient data to recommend the use of this approach for hip and major knee surgery. PCB is a safe and effective alternative for analgesia after hip and knee surgery. More research is required to define its role in the intraoperative setting and confirm potentially beneficial effects on variables such as perioperative haemodynamics and blood loss.
