Perineural dexamethasone in ultrasound-guided interscalene brachial plexus block with levobupivacaine for shoulder arthroscopic surgery in the outpatient setting: randomized controlled trial

Background. Both dexamethasone and dexmedetomidine are commonly used local anaesthetic adjuvants in brachial plexus block to enhance the blocking effect. However, it is unclear which of the two drugs is more effective in a brachial plexus block. This article compares the effects of dexamethasone and dexmedetomidine combined with local anaesthetics in brachial plexus block through meta-analysis, availing information for current practice and future research. Methods. We conducted a search of the PubMed, Embase, Cochrane Library, and Web of Science databases to identify studies investigating the effects of dexamethasone and dexmedetomidine combined with local anaesthetics on brachial plexus block. The databases were searched from their inception to October 2021. Clinical randomized controlled trials were included. Two researchers independently conducted literature screening. The Cochrane System Review Manual was adopted for literature quality evaluation, whereas Stata 14.0 software aided in the meta-analysis. The duration of analgesia was the primary outcome indicator; whereas, the secondary outcome indicators included the duration of sensory block and motor block. Results. Seven articles were analysed, including 465 patients. Compared to the dexmedetomidine group, the dexamethasone group exhibited longer durations of analgesia (WMD = 111.29, 95% CI: 16.49–206.10, P = 0.021), sensory block (WMD = 173.20, 95% CI: 86.69–259.71, P < 0.0001), and motor block (WMD = 121.03, 95% CI: 12.87–229.20, P = 0.028). Conclusion. The present meta-analysis results affirm that dexamethasone is a better local anaesthetic adjuvant in brachial plexus block that enhances the blocking effect. Nevertheless, the existing heterogeneity warrants additional large-scale, multicentre, high-quality randomized controlled trials in the future for further verification and to provide more reliable clinical evidence.

BACKGROUNDPeripheral regional anaesthesia is frequently used for upper extremity surgery. To prolong the duration of analgesia, adjuvants can be added to single-injection local anaesthetics. Despite attempts to compare several adjuvants in pairwise meta-analyses, a comprehensive comparison is still missing.OBJECTIVEThe objective of this network meta-analysis was to determine the effectiveness of adjuvants in upper extremity peripheral nerve blocks.DESIGNA systematic review of randomised controlled trials with network meta-analyses.DATA SOURCESA literature search in Embase, CENTRAL, MEDLINE and Web of Science was performed up to March 2023.ELIGIBILITY CRITERIARandomised trials comparing different adjuvants injected perineurally in peripheral upper extremity nerve blocks were eligible. Frequentist network meta-analysis was conducted using a random effects model with physiological saline as the comparator. The primary endpoint was the ratio of means (ROM) of the duration of analgesia.RESULTSThe review included 242 randomised controlled trials with a total of 17 391 patients. Twenty-eight adjuvants were compared in the largest networks. Most network estimations consisted of a high proportion of direct evidence. Fourteen adjuvants increased the duration of analgesia significantly by the following factors, ROM [95% confidence interval (CI)]: dexamethasone 1.95 (1.79 to 2.13), buprenorphine 1.83 (1.51 to 2.24), butorphanol 1.84 (1.41 to 2.39), potassium chloride 1.89 (1.15 to 3.11), dexmedetomidine 1.70 (1.59 to 1.81), sufentanil 1.70 (1.27 to 2.29), ketorolac 1.68 (1.24 to 2.27), midazolam 1.55 (1.24 to 1.94), tramadol 1.52 (1.32 to 1.75), nalbuphine 1.50 (1.30 to 1.72), morphine 1.43 (1.09 to 1.88), magnesium sulfate 1.42 (1.20 to 1.67), clonidine 1.36 (1.24 to 1.50) and fentanyl 1.23 (1.08 to 1.40). Inconsistency in network meta-analysis was substantial. Overall side effect rates were low with all adjuvants.CONCLUSIONThe best interventions to prolong the duration of analgesia were dexamethasone, followed by dexmedetomidine, opioids, electrolytes, ketorolac and midazolam. There are general concerns about the quality of underlying studies and the risk of publication bias.TRIAL REGISTRATIONPROSPERO 2018 CRD42018115722
