BACKGROUND Although a brachial plexus block can be used to provide anesthesia and analgesia for upper extremity surgery, its effects using MgSO(4) on postoperative pain management have not been reported. The aim of this study was to evaluate brachial plexus block using MgSO(4) on postoperative analgesia. METHODS Thirty-eight patients who were scheduled to undergo upper extremity surgery were ...

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...

BACKGROUND The interscalene brachial plexus block (ISBPB) is a most reliable and commonly performed technique for regional anesthesia of the upper extremity. It has widespread clinical applicability, ranging from use for shoulder surgery as well as diagnostic and therapeutic uses in pain management. Traditional methods described for performing the ISBPB involve identifying surface anatomy landm...

PURPOSE To update the gross and sonographic anatomy and propose landmarks to perform ultrasound-guided (US-guided) axillary brachial plexus block (BPB) in rabbits. METHODS Forty New Zeeland's rabbit (NZR) cadavers were dissected and the nerves were trimmed, identified, measured, and photographed. Additionally, in twenty NZRs, sonographic images of brachial plexus (BP) were performed through a...

this blinded, randomized experimental study was designed to evaluate the analgesic effects of adding epinephrine or xylazine to lidocaine solution for brachial plexus block (bpb) in sheep. nine healthy, fat-tailed female lambs (26.6 ± 1.5 kg) were randomly allocated into three groups: lidocaine 2%, 5 mg kg-1 (lid, n = 6), lidocaine (5 mg kg-1) with epinephrine 5 µg ml-1 (lidep, n = 6) or lidoca...

To the Editor:—We read with interest the recent report by Martinez et al. regarding a combined infraclavicular plexus blockade with suprascapular nerve block for humeral head surgery in a patient with severe respiratory failure. However, we have some concerns with regard to the following points: First, it is not clearly stated whether the authors performed an infraclavicular plexus block using ...

A case report of a 35-year-old female with large low-grade chondrosarcoma the left humerus. Resection was performed under regional anaesthesia (interscalene brachial plexus block): this is useful technique where there are limited resources and during COVID-19 pandemic.

Introduction: Different types of additives are commonly used to prolong the duration of brachial plexus block.The present study was aimed to test the hypothesis that dexmedetomidine produces a superior analgesia, motor block and post operative analgesia when added as an adjuvant to ropivacaine 0.5% in supraclavicular brachial plexus block. Materials andMethods: A total of 100 patients (20-50 ye...

Interscalene block is used for shoulder surgeries however it almost always results in phrenic nerve palsy1,2. Some anaesthesiologists have described careful ultrasound guided low volume (5mls only) of local anesthetic interscalene which does not cause hemidiaphragmatic paresis3. However we present to you a case where implied recently technique sparing involving combination oblique infraclavicul...
