Abstract Background The coracoid approach is a simple method to perform ultrasound-guided brachial plexus regional anesthesia (RA) but its simplicity is counterbalanced by a difficult needle visualization. We hypothesized that the retroclavicular (RCB) approach is not longer to perform when compared to the coracoid (ICB) approach, and improves needle visualization. Methods This randomized, controlled, non-inferiority trial conducted in two hospitals, included patients undergoing distal upper limb surgery. Patients were randomly assigned to a brachial plexus block (ICB or RCB). The primary outcome was performance time (sum of visualization and needling time), and was analyzed with a non-inferiority test of averages. Depth of sensory and motor blockade, surgical success, total anesthesia time, needle visualization, number of needle passes and complications were also evaluated. Subgroup analysis restricted to patients with higher body mass index was completed. Results We included 109 patients between September 2016 and May 2017. Mean RCB performance time was 4.8 ± 2.0 min while ICB was 5.2 ± 2.3 min (p = 0.06) with a 95% CI reaching up to 5.8% longer. RCB conferred an ultrasound-needle angle closer to 0° and significantly improved needle visibility after the clavicle was cleared and before local anesthetic administration. No differences were found in the secondary outcomes. Similar results were found in the subgroup analysis. Conclusion RCB approach for brachial plexus anesthesia was similar to ICB approach in terms of time performance. Needle visibility, which represent an important clinical variable, was superior and angle between needle and ultrasound probe was close to 0° in the RCB group. Clinical trial registration ClinicalTrials.gov (NCT02913625), registered 26 September 2016.

Subgroup analysis restricted to patients with higher body mass index was completed. Results: We included 109 patients between September 2016 and May 2017. Mean RCB performance time was 7.1% shorter than ICB (retro: 4.8 ± 2.0 min; infra: 5.2 ± 2.3 min, p=0.06) with a 95% CI reaching up to 5.8% longer. RCB conferred an ultrasound-needle angle closer to 0° and significantly improved needle visibility after the clavicle was cleared and before local anesthetic administration. No differences were found in the secondary outcomes. Similar results were found in the subgroup analysis. Conclusion: In patients undergoing distal upper limb surgery with an infraclavicular anesthesia, performance time with RCB approach was deemed clinically similar to ICB approach while improving needle visibility.

<b><i>Background:</i></b> The supraclavicular approach to brachial plexus block is a commonly employed regional anesthesia technique for providing surgical anesthesia and postoperative analgesia for patients undergoing upper limb fractures. With ultrasound (US) guidance, the success rate of the block is increased, and complications like pneumothorax and vascular puncture are minimized. The block can be performed using single injection at the corner pocket or double injection, that is, half of the drug at the corner pocket and the remaining half at the cluster of brachial plexus divisions. <b><i>Methods:</i></b> After institutional ethics committee approval, we randomized 40 patients scheduled with fractures for elective upper extremity surgery under US-guided supraclavicular brachial plexus block. Twenty patients received 30 mL of local anesthetic at the corner pocket (group SI), and 20 patients received 30 mL of local anesthetic using the dual-injection technique in divided doses (group DI). Demographic data, time to block performance, time to sensory and motor block, total anesthesia-related time (TART), block success, and failure were compared between both groups. <b><i>Results:</i></b> The demographic data were comparable between both groups. The DI group had a significantly faster onset than the SI group (<i>p</i> = 0.0172). There was a statistically significant lesser performance time in group SI than in group DI (<i>p</i> &#x3c; 0.034). The sensory and motor block achieved was comparable between both groups. <b><i>Conclusion:</i></b> The success rates in both the SI and DI techniques are comparable. The DI technique results in a faster onset and hence a shorter TART; however, it may not be clinically relevant.

Background: Adding narcotics to local anesthetic is very effective in prolonging the analgesic effects. The aim of this study is to evaluation the efficacy and safety of fentanyl as an adjuvant with bupivacaine-lignocaine in supraclavicular block. Methods: This analytical study was carried out in the department of anesthesiology in Chittagong Medical College Hospital in collaboration with the department of orthopedic surgery over a period of 22 months starting from January 2012 to December 2014. A total 130 adult patients of either sex with American Society of Anesthesiology (ASA) health status I-II were selected for upper limb surgery under supraclavicular brachial plexus block was randomly allocated in to two groups of 65 patients in each. Group- C was received Distilled water 2ml and Group-F was received fentanyl 2ml (100 g) in 38ml of bupivacaine and lignocaine with adrenaline (Total volume of 40ml). Results: The mean onset of sensory & motor block was 10.49±0.75 min & 9.41±0.76 min in group-C and 7.60±3.711min & 9.23±5.114min in group-F. The duration of analgesia in group-C was 3.81±0.88 hrs and in group-F was 8.62±1.747 hrs. Conclusion: There was significantly prolonged duration of analgesia and better onset of sensory and motor block in fentanyl group without any unwanted effects.
