Clinical Trial
Brachial plexus examination and localization using ultrasound and electrical stimulation: a volunteer study.
Current techniques of brachial plexus block are "blind," and nerve localization can be frustrating and time consuming. Previous studies on ultrasound-assisted brachial plexus blocks are mostly performed with scanning probes of 10 MHz or less. The authors tested the usefulness of a state-of-the-art, high-resolution ultrasound probe (up to 12 MHz) in identifying the brachial plexus in five locations of the upper extremity and in guiding needle advancement to target before nerve stimulation. ⋯ These preliminary data show that the high-resolution L12-L5 probe provides good quality brachial plexus ultrasound images in the superficial locations i.e., the interscalene, supraclavicular, axillary, and midhumeral regions. The needle technique described here for ultrasound-assisted nerve localization provides real-time guidance and is potentially valuable for brachial plexus blocks.

[Sciatic nerve block by the lateral route at the level of the popliteal fossa with 0.75% ropivacine: advantages of a more proximal approach].
To assess the efficacy of a sciatic nerve block using a lateral approach 11 cm cephalad to the lateral femoral epicondyle for providing surgical anesthesia and postoperative analgesia in scheduled foot surgery (hallux valgus) after a single injection of 30 mL of 0.75% ropivacaine. ⋯ The sciatic nerve block from a lateral approach 11 cm cephalad to the lateral femoral epidondyle is an appropriate anesthetic technique for foot surgery. It is safe, effective and easy to perform. Infusion of 30 mL of 0.75% ropivacaine provided adequate anesthesia and long-lasting postoperative analgesia for our patients.

Brachial plexus blocks: infusions and other mechanisms to provide prolonged analgesia.
Regional anesthesia has numerous benefits for upper extremity surgery such as improved analgesia, opioid sparing and reduced side effects. However, many of these advantages are lost after block regression. Recently, several strategies such as continuous ambulatory local anesthetic infusions and adjuvants that may potentiate analgesia after a brachial plexus block have been described and investigated. This review will highlight and place in context this recent work. ⋯ The advances and techniques recently described demonstrate that prolonging analgesia after brachial plexus blocks is possible. This may be accomplished via several different approaches and mechanisms resulting in improved patient analgesia and side effects.

Randomized Controlled Trial Comparative Study Clinical Trial
Prospective study comparing two methods of anaesthesia for prostate biopsies: apex periprostatic nerve block versus intrarectal lidocaine gel: review of the literature.
Studies have demonstrated the need for pain control during multiple transrectal prostate biopsies. Due to encountered published results on periprostatic nerve block, we prospectively evaluated the efficacy and safety of periprostatic local anaesthesia at the apex in comparison to intrarectal lidocaine gel. ⋯ Periprostatic nerve block at the apex is superior to intrarectal lidocaine gel for controlling pain during transrectal prostate biopsy, with no increased complications. This technique should be recommended for those patients without anal or rectal inflammatory diseases.
