Case Reports[Convulsions induced by ropivacaine after midhumeral block].
We report a case of central nervous system toxicity induced by ropivacaine following a brachial block at the humeral canal. Forty millilitres 0.75% ropivacaine (4.28 mg.kg-1) were used uneventfully, with slow injections and negative intermittent aspirations. Fifteen minutes later, the patient presented two episodes of generalised convulsions treated by diazepam, 20 mg. The total venous ropivacaine concentration measured two hours after the block was 2.3 mg.l-1.

Clinical Trial
[The modified technique of continuous suprascapular nerve block. A safe technique in the treatment of shoulder pain].
This study assesses a modified approach for suprascapular nerve block in a single shot and continuous catheter technique for the treatment of chronic shoulder pain. After thorough anatomic examinations, a new technique was performed in 30 patients by inserting the catheter into the suprascapular fossa. Complications of the technique, time of onset, effect and patient satisfaction were evaluated. ⋯ Local inflammation occurred in one patient and dislocation of the catheter in another patients. Patient satisfaction (97%) was very high. The modified technique of continuous suprascapular nerve block is a safe and easy-to-perform technique in the treatment of acute and chronic shoulder pain.

A new posterior approach to the sciatic nerve in the subgluteal region was developed. We describe our clinical experiences on 135 consecutive patients. ⋯ The study demonstrated that the sciatic nerve can be easily blocked using this new posterior subgluteal approach, suggesting that it represents a safe and effective alternative to block the sciatic nerve at a proximal level, with the potential for reducing the discomfort experienced by the patient during block placement.

Successful interscalene block with a nerve stimulator may also result after a pectoralis major motor response.
Interscalene block of the brachial plexus is a well-established anesthetic and analgesia technique for shoulder surgery. The endpoint for successful block using the nerve stimulator has been described by previous authors as a bicep motor response (twitch) and recently by a deltoid motor response. This retrospective observational case study of regular clinical practice examined the efficacy of using the pectoralis major motor response as an endpoint for a successful block. ⋯ This retrospective observational case study of regular clinical practice suggests that a pectoralis major motor response can be a satisfactory endpoint for interscalene block.
