Comparison of Fentanyl and Dexmedetomidine as an Adjuvant to Bupivacaine in Supraclavicular Brachial Plexus Block: A Randomized-Double Blind  Prospective Study

Background: Brachial plexus block is preferred to general anesthesia (GA) as it reduces many complications of GA, provides good intra and postoperative analgesia, adequate muscle relaxation. Addition of adjuvants along with LA is used to prolong block with improved quality of anesthesia and decrease dose of LA. This study was done to see the efficacy of Ropivacaine with dexmedetomidine and fentanyl in terms of duration of action and pain relief. Aims and Objectives: Dexmedetomidine and Fentanyl along with Ropivacaine in patients undergoing upper limb surgeries, the onset and duration of sensory and motor blockade as well as post op analgesia is compared. Materials and Methods: Prospective Randomized Comparative study with three groups randomly divided received total volume of 30 mL of drug in peripheral nerve stimulator guided supraclavicular blocks in patients undergoing upper limb surgeries. Group Dexmedetomidine received 28 cc of 0.75% Ropivacaine and Dexmedetomidine (1 mcg/kg), Group Fentanyl patients received 28 cc of 0.75% Ropivacaine and fentanyl (1 mcg/kg), whereas, group plain Ropivacaine patients received 28 cc of 0.75% Ropivacaine and 2 mL of normal saline. Haemodynamics, sensory and motor block (MB) were evaluated by VAS and modified Bromage scale. Results: The onset of sensory block and MB in the dexmedetomidine group, fentanyl group, and ropivacaine groups was 3.57±0.50 min and 4.47±0.51 min, 5.50±0.51 min and 7.53±0.51 min, and 8.07±0.79 min and 10.07±0.79 min respectively which were statistically significant. The duration of MB in the dexmedetomidine group, fentanyl group, and ropivacaine group were 6.57±0.50 h, 4.47±0.51 h, and 2.50±0.51 h respectively which was statistically significant (P=0.0000). The duration at which first postoperative analgesia was required in the dexmedetomidine group, fentanyl group, and ropivacaine group were 8.57±0.50 h, 6.57±0.50 h, and 5.30±0.47 h respectively. Conclusion: Dexmedetomidine is better as an adjuvant to Ropivacaine for brachial plexus block in terms of onset and duration.

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
