Comparative Study Clinical TrialPatient acceptance of interscalene block for shoulder surgery.
Regional anesthesia can be applied to shoulder surgery with an expected high success rate. To determine the level of patient satisfaction with regional anesthesia, we studied a group of patients who had undergone shoulder surgery more than once, with general anesthesia on one occasion and regional on another. ⋯ Interscalene brachial plexus block is well accepted by patients for reconstructive shoulder surgery.

Randomized Controlled Trial Clinical Trial[Axillary plexus block by simultaneous blockade of several nerves. I. Influence of the volume of the anesthetic solution].
The influence of the volume of local anaesthetic solution on axillary blockade was investigated in a prospective randomized double-blind study including 120 patients presenting for upper limb surgery. A peripheral nerve stimulator was used to carry out the axillary block with a multiple injection technique. The musculocutaneous, radial, median and ulnar nerves were routinely stimulated. ⋯ The data demonstrated that, for a same amount of local anaesthetic, the larger volumes provided better quality sensory blockade than the smaller ones (p < 0.03). However, the volume of solution used affected neither the time of onset nor the duration of anaesthesia, nor the degree of motor blockade. It is concluded that, despite the use of a neurostimulator and simultaneous infiltration of several nerve trunks, the volume required to ensure a reliable degree of sensory block with the technique of axillary block is comprised between 40 and 50 ml (25 ml.m-2).

Regional anesthesia represents a selective approach in shoulder surgery. The following technics can be used: brachial plexus block, cervical epidural and intra-articular anesthesia. The advantages of each technique are discussed.

Comparative Study[Shoulder surgery using a plexus block: for or against. Against].
Brachial plexus block is an alternative and elegant procedure for shoulder surgery. Three main concerns have to be considered when this technique is planed. ⋯ Thirdly, when nerve lesions of different mechanisms including plexus block itself occur, the origin of the lesion may be difficulty related to its cause. Indications of cervical block are therefore to be considered cautiously when shoulder surgery is performed.
