conclusions the volume of the injected anesthetic accelerated the onset of sensory and motor block without affecting the rate of success in our patients. results the onset of sensory and motor block was significantly shorter in the 1.3% lidocaine group than in the 2% lidocaine group (p ≤ 0.05). the success rate of sensory and motor block was not different. the quality (completeness) of sensory ...

Objectives: Dexmedetomidine has been utilized as an adjuvant to prolong single local anaesthetic injection technique in brachial plexus block despite of adverse effects and cost-effectiveness. Morphine, a classic opioid, is also used as an adjuvant in neuraxial and perineural nerve blocks. In this study, we compared the effects of these two different adjuvants to ropivacaine in interscalene bra...

in upper brachial plexus (c5-c6 or c5-c6-c7 roots) injuries, restoration of elbow flexion is the first aim. several methods have been used to achieve this goal. among these procedures, oberlin’s method (transfer of part of ulnar nerve to the nerve to biceps muscle) is the newest one. from april 2002 to march 2003 we used this method in 9 cases, 8 males and 1 female, of upper brachial plexus inj...

In 1970, Winnie proposed the brachial plexus block as an alternative and effective anaesthesia technique for shoulder surgery. From that date, several techniques have been developed to approach the brachial plexus: the use of a nerve stimulator and, more recently, the ultrasound guided nerve blockade have made the procedure easier and more effective; the availability of the new drugs demonstrat...

UNLABELLED In this study, we evaluated state-of-the-art ultrasound technology for supraclavicular brachial plexus blocks in 40 outpatients. Ultrasound imaging was used to identify the brachial plexus before the block, guide the block needle to reach target nerves, and visualize the pattern of local anesthetic spread. Needle position was further confirmed by nerve stimulation before injection. T...

conclusions our study showed that dexmedetomidine had better effects on sensory and motor block duration and motor block onset in comparison with ketorolac, as lidocaine adjuvants in infraclavicular brachial plexus block were present in both protocols. however, the first time to analgesic request by ketorolac was longer than dexmedetomidine. objectives the purpose of this study was to examine t...

BACKGROUND Multiple needle attempts to gain a muscle twitch or a paresthesia for a classical supraclavicular brachial plexus block can increase the risks of nerve damage or pain. The aims of this study were to obtain reliable clinical data on ultrasound-guided supraclavicular blocks, demonstrate the higher success rate and fewer complications, and design an injection method for patients whose b...

In the treatment of brachial plexus injury, nerves that are functionally less important are transferred onto the distal ends of damaged crucial nerves to help recover neuromuscular function in the target region. For example, intercostal nerves are transferred onto axillary nerves, and accessory nerves are transferred onto suprascapular nerves, the phrenic nerve is transferred onto the musculocu...

Background. For hand surgery, brachial plexus blocks provide effective anesthesia but produce undesirable numbness. We hypothesized that distal peripheral nerve blocks will better preserve motor function while providing effective anesthesia. Methods. Adult subjects who were scheduled for elective ambulatory hand surgery under regional anesthesia and sedation were recruited and randomly assigned...
