Objectives: To compare ultrasound guidance (USG) and electrical neurostimulation guidance (ENSG) in axillary brachial plexus block in terms of block performing time, sensory and motor block quality, and patient satisfaction. Methodology: 200 patients undergoing elective carpal tunnel syndrome surgery were randomly assigned to one of two groups; the USG group or the ENSG group. Axillary blocks were performed with a mixture of 15 ml of lidocaine 2% and 15 ml of bupivacaine 0.5% (a total of 30 ml solution). Sensory block was evaluated with a pinprick test and motor block was evaluated via the Bromage scale by a blinded observer. Results: Block performing time was significantly shorter in the USG group than in the ENSG group (P<0.001). The sensory and motor block onset times were significantly shorter and the additional analgesic requirements were significantly lower in the USG group than in the ENSG group (P<0.001). Conclusion: USG is better than ENSG in axillary brachial plexus block in terms of block performing time, block quality and patient satisfaction.

Brachial plexus block is a suitable alternative to general anaesthesia for patient undergoing upper extremity surgery. Ropivacaine the S-enantiomer emerged as a possible replacement of Bupivacaine without undesirable toxic effects.Therefore this study was conducted to assess the block characteristics and side effects of 0.75% ropivacaine in axillary brachial plexus block for forearm surgeries. This interventional study was carried out in 30 patients of ASA physical status I or II, aged 18 to 60 yrs undergoing elective surgery u nder axillary brachial plexus block with 20 ml of 0.75 % Ropivacaine using ultrasound and nerve stimulator. The mean onset time of sensory block was 4.53 ± 1.18 minutes and duration of sensory block was 491.00 ± 57.45 minutes. The mean onset time of motor block was 9.17 ± 1.39 minutes and duration of motor block was 452.50 ± 52.34 minutes. The mean time for rescue analgesia or total analgesic effect was 569.47 ± 88.46 minutes. No patients developed any side effects. The result of this study concluded that Ropivacaine is a safe drug providing longer duration of sensory analgesic effect and early recovery of motor function with good operating conditions for forearm surgeries under brachial blexus block.

Abstract Background Brachial plexus block has substituted general anesthesia in the majority of patients planned for upper limb surgeries as it avoids the undesired effects of the medications used in general anesthesia as well as the stress response associated with airway manipulation. Opioid agonist–antagonists such as nalbuphine are used as adjuvant to improve the anesthetic properties of bupivacaine. Verapamil has an additive effect in brachial plexus blockade in the form of decreasing the consumption of analgesics in the postoperative period with reducing onset time and extending the duration of motor and sensory blockade. The aim of this study is to investigate the adjuvant effect of verapamil versus nalbuphine to 0.5% bupivacaine in brachial plexus block as regards onset, duration of sensory and motor blockade and postoperative analgesic augmentation. The study is randomized, prospective, double-blinded, comparative study where 90 patients subjected to arm, forearm and hand surgeries were randomized into three groups, group A received 30 ml of plain bupivacaine 0.5% plus 2 ml of normal saline, group B received 30 ml of bupivacaine 0.5% plus 2 ml verapamil equivalent to 5 mg, group C received 30 ml of bupivacaine 0.5% plus 10 mg of nalbuphine diluted in 2 ml of normal saline. Results Results of this study showed that group C and group B sensory block time onset was 7.25 ± 1.5 vs. 10.92 ± 3.84 min, P < 0.001 and was shorter than that in group A (13.2 ± 2.66 min). In addition, the motor block onset was (11.10 ± 1.24 vs. 13.50 ± 3.77 min, P < 0.001) shorter than group A (17.16 ± 1.30 min). In group C and group B, sensory block duration was 396 ± 32.17 vs. 355.83 ± 18.48 min, P < 0.001, respectively and was longer than that in group A (321.13 ± 25.08 min). Also, there was prolonged motor block duration in group C and group B recording (338.92 ± 25.2 vs. 302.93 ± 15.24 min, P < 0.001) and was longer than that in group A (280.70 ± 32.35 min). Time of demand of rescue analgesia dose was significantly long in group C and group B (449.53 ± 52.45 vs. 418.13 ± 41.12 min, P < 0.001) and was longer than group A (361.31 ± 21.42 min). Both verapamil and nalbuphine have additive effect to bupivacaine improving the all anesthetic parameters of the block. Conclusion Both drugs produce favorable enhancement of time onset and effective prolongation of duration of sensory and motor blockade and extend the period of postoperative analgesia with superiority to nalbuphine over verapamil.

This study evaluated the effects of adding adjuvant clonidine to lidocaine with epinephrine on the characteristics of ultrasound-guided axillary brachial plexus block (ABPB) for upper extremity surgery. Twenty-four patients were randomised to receive an ultrasound guided ABPB with 20 mL of lidocaine 2% with 1:200,000 epinephrine plus 2 mL of either normal saline 0.9% (Group 1) or a mixture of clonidine 1 µg/kg and normal saline 0.9% (Group 2). The outcome measures that were recorded were the overall onset time and the duration of sensory and motor block. The median (IQR) overall onset time of sensory and motor block was significantly shorter in Group 2 vs. Group 1 (5 (5–7.5) min vs. 10 (8.8–12.5) min; p < 0.001) and (5 (2.5–7.5) min vs. 7.5 (6.3–7.5) min; p = 0.001), respectively. The median (IQR) overall duration of sensory and motor block was significantly longer in Group 2 vs. Group 1 (225 (200–231) min vs. 168 (148–190) min; p < 0.001) and (225 (208–231) min vs. 168(148–186) min; p < 0.001), respectively. In ultrasound-guided ABPB, the addition of clonidine to lidocaine with epinephrine resulted in shorter onset time and prolonged duration of sensory and motor block.

AbstractUltrasound-guided axillary brachial plexus block is increasingly used in preschool-age patients. However, the minimum effective volume of local anaesthetics has not been determined. With ethical committee approval and written informed consent from the guardians of all paediatric patients, we studied 27 consecutive patients aged 3 to 6 years who were scheduled for hand surgery. After general anaesthesia, eligible patients received a set volume of ultrasound-guided axillary brachial plexus block. We determined the volume of 0.2% ropivacaine for consecutive patients from the preceding patient’s outcome. The initial volume was 0.4 ml/kg. The testing interval was set at 0.05 ml/kg, and the lowest volume was 0.1 ml/kg. The following conditions were defined as a successful block: no heart rate changes, body movement, or ventilatory disorders during the operation; no use of fentanyl in the PACU; and a postoperative sensory block score < 3. The sequences of positive and negative blocks in consecutive patients were recorded. Using probit regression analysis, the 50% effective volume was 0.185 ml/kg (95% CI 0.123–0.234), and the 95% effective volume was 0.280 ml/kg (95% CI 0.232–0.593). EV50 and EV95 values of 0.2% ropivacaine for ultrasound-guided axillary brachial plexus block were 0.185 ml/kg and 0.280 ml/kg, respectively.

Brachial plexus block provide surgical anesthesia and analgesia of upper extremity. Any adjuvant to brachial plexus block have less systemic side effect as well as reduce the total dose local anaesthetics. The midazolam acts on GABA-A receptors in peripheral nerve. The sensory and motor block was significantly faster in our study who received midazolam. This could be local anesthetic properties of midazolam and synergistic action with local anaesthetics. Total 100 patients between ages 10-77 years of either sex of ASA I-III, underwent upper arm surgery were given supraclavicular brachial block with and without midazolam. The onset and duration of sensory block in Gr I (XB) and Gr II (XBM) were significantly different. The onset time for sensory block was significantly prolong and duration of block significantly less compared to Gr II (P<0.05). The onset time for motor block was significantly less and duration significantly higher in Gr II (XBM) as compared to Gr I (XB). Midazolam 50ugm/kg in brachial plexus block speed sensory and motor block with post operative analgesia.

Background: As compared to general anaesthesia, brachial plexus block for upper limb surgery gives fewer side effects and better postoperative analgesia. The objective of this study was to evaluate the effects of 0.5% levobupivacaine and compare it with 0.75% ropivacaine.Methods: For this prospective randomized, controlled study, 60 patients of both sexes of ASA grade 1 and 2 were enrolled and divided into two groups and supraclavicular brachial plexus block was performed by lateral approach using 30 ml of 0.5% levobupivacaine and 0.75% ropivacaine. The onset of sensory and motor block, duration of sensory and motor block and analgesia and possible adverse events were recorded.Results: No statistically significant difference was observed in the onset of sensory block in both groups. Onset of motor block was significantly faster in levobupivacaine group (P<0.05). Duration of sensory block, motor block and analgesia was significantly longer in levobupivacaine group (P<0.05).Conclusions: 0.5% levobupivacaine is better alternative to 0.75% ropivacaine in brachial plexus block in term of early onset of sensory block and long duration of analgesia.

BACKGROUND To improve the quality of block (sensory and motor characteristics), postoperative pain management and reduce large doses of local anaesthetics, various adjuvants are used with local anaesthetic agents. We have evaluated dexmedetomidine as an adjuvant to 0.5 % ropivacaine in supraclavicular brachial plexus block in terms of onset and duration of sensory and motor block & duration of postoperative analgesia. METHODS This is a prospective randomised comparative study. 60 patients who were admitted for elective surgeries of the lower arm, at the level of elbow, forearm & hand were enrolled. They were divided in to two groups of 30 patients each as follows - group RD: supraclavicular brachial plexus block given with 30 mL of 0.5 % ropivacaine + 1 mL (100 μg) of dexmedetomidine. Group RC: supraclavicular brachial plexus block given with 30 mL of 0.5 % ropivacaine + 1 mL of normal saline. Various parameters like onset times and durations of sensory and motor block, duration of analgesia, total analgesic needed, and side-effects were recorded for each patient. RESULTS The time of onset of sensory and motor block was significantly early in dexmedetomidine group than in control group. The duration of sensory and motor block was significantly prolonged in group RD as compared to group RC. The duration of sensory block was 724.18 + 73.26 min in group RD (GD) and 582.16 + 93.12 min. in group RC (GC). The duration of analgesia was significantly prolonged in group RD. CONCLUSIONS Addition of dexmedetomidine as an adjuvant to ropivacaine is associated with early onset of sensory and motor block. The duration of sensory and motor block was prolonged. The duration of analgesia was prolonged and patients required less rescue analgesia. The use of dexmedetomidine was associated with reversible bradycardia and sedation score was less KEYWORDS Ropivacaine, Dexmedetomidine, Adjuvant, Supraclavicular Brachial Plexus Block
