Comparative Study
Changes in median nerve somatosensory transmission and motor output following transient deafferentation of the radial nerve in humans.
To determine if transient anaesthetic deafferentation of the radial nerve would lead to alterations in processing of early somatosensory evoked potentials (SEPs) from the median nerve or alter cortico-motor output to the median nerve innervated abductor pollicis brevis (APB) muscle. ⋯ Transient deafferentation of the radial nerve, which supplies wrist and hand extensor muscles, has been shown to alter sensory processing from and motor output to the median nerve innervated thenar muscles.

[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.

Case ReportsUltrasound guidance for ulnar nerve block in the forearm.
The objective of this study was to establish the feasibility of ulnar nerve block under direct imaging. ⋯ Ultrasound guidance for ulnar nerve block in the forearm is a promising technique that includes block of the dorsal cutaneous branch. Anatomic and sonographic considerations are discussed.

For the repair of an open injury to the hand, a continuous axillary block was performed in a 40- year-old male patient. Slight resistance was experienced during advancement of the catheter. ⋯ Three days later the removal of the catheter proved to be difficult due to a knot in the distal part of the catheter. This seems to be the first report of a knot in a catheter used for continuous axillary plexus block.

Case ReportsShoulder dislocation after infraclavicular coracoid block.
We report a case of shoulder dislocation after a brachial plexus block with a double-injection technique using the infraclavicular coracoid approach. ⋯ When motor block of the muscles of the shoulder occurs after brachial plexus anesthesia, special care must be taken in patient positioning to avoid shoulder dislocation.
