Background and objectives: Brachial plexus block is commonly used in shoulder surgery, as it provides satisfactory surgical conditions and adequate postoperative pain control. However, there are contradictory reports regarding the addition of tramadol to the injected regional anesthetic solution. We performed a prospective randomized study to evaluate the effectiveness of tramadol as an adjuvant to ropivacaine during interscalene brachial plexus block and assess its impact on the opioid consumption and the early postoperative pain in patients that underwent shoulder surgery. Materials and Methods: Eighty patients scheduled for elective shoulder surgery and anesthesia via interscalene brachial plexus block were randomly divided into two groups. In group A (n = 40), a solution of 40 mL of ropivacaine 0.5% and 2 mL (100 mg) of tramadol was administered during the brachial plexus block, while in group B (n = 40), a solution of 40 mL of ropivacaine 0.5% and 2 mL NaCl 0.9% (placebo) was administered. The effectiveness and duration of sensory and motor blocks were recorded in both groups. The sensory block was assessed recording the loss of sensation to pin prick test over the skin distribution of the axillary, radial, and musculocutaneous nerves. The motor block was assessed using the modified 3-point Bromage score (0–2 points). Cumulative morphine consumption and pain, using the Visual Analog Scale (VAS), were evaluated in both groups at 2, 4, 8, and 24 h after surgery. Results: Sensory block onset was achieved earlier in group A than in group B (5.21 ± 3.15 minutes (min) vs. 7.1 ± 4.51 min, p = 0.029). The motor block onset was similar between the two groups (13.08 ± 6.23 min vs. 13.28 ± 6.59 min; p = 0.932). The duration of the sensory block was longer in group A as compared to group B (13 ± 2.3 h vs. 12 ± 2.8 h; p = 0.013). The duration of the motor block did not present any difference between the groups (10 ± 2.2 h vs. 10 ± 2.8 h; p = 0.308). Differences in morphine administration were not significant at 2, 4, and 8 h, however, morphine consumption was found to be decreased in group A 24 h postoperatively A (p = 0.04). The values of VAS were similar at 2, 4, and 8 h, however, they were lower in group A at 24 h (p < 0.013). Conclusions: Combined regional administration of tramadol and ropivacaine during interscalene brachial plexus block improves the time of onset and the duration of the sensory block, while it is associated with reduced morphine consumption during the first 24 h after shoulder surgery.

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.

Introduction: Many-a-time local anaesthesia appears as a very effective alternative of general one. Different additives have been used to prolong regional blockade. Objective: This prospective study designed to evaluate the effect of dexamethasone added to local anaesthetics on the onset and duration of supraclavicular brachial plexus block. Methods: Sixty adult patients undergoing various orthopaedic surgeries on forearm and around the elbow under supraclavicular brachial plexus block were selected and divided into 2 groups of 30 each. In group-A patients received 35 ml of mixture of lignocaine 2%, bupivacaine 0.5% while in group-B patients received the same amount of local anaesthetics with dexamethasone (8 mg). The onset of sensory and motor block and duration of analgesia in two groups were compared and development of complications were observed. Result: The two groups were comparable in demographic data. The mean onset time of sensory block was 11.64±2.19 minutes in group A and 9.89±1.97 minutes in group B and difference was statistically significant (p<0.05). Onset of motor block was 13.32±0.98 minutes in group A and 11.09±1.28 minutes in group B and difference was statistically significant (p<0.05). There was markedly prolonged duration of analgesia in group-B, 11.87± 0.53 hours compared to group-A, 3.43±0.49 hours. The result was statistically highly significant (p<0.001). Both the groups had high success rate (>90%). The incidence of complication was low in both the groups. Conclusion: Addition of dexamethasone as an adjuvant to local anaesthetics in brachial plexus block results in significantly early onset and markedly prolonged duration of analgesia without any unwanted effects.

Background: Regional anaesthesia and analgesia, has the potential to provide excellent operating conditions along with better and prolonged post-operative with pain relief with fewer side effects. As a result, it is becoming increasingly popular for ambulatory anaesthesia and for day care patients.. Among the commonly used local anaesthetics, lignocaine and bupivacaine, bupivacaine has significant cardiovascular and central nervous system toxicity. In addition, bupivacaine also has lesser differentiation between sensory and motor blockade post-operatively. Ropivacaine and levobupivacaine were developed to avoid the bupivacaine related toxicities. The clinical safety profile of ropivacaine seems to be more favourable than that of levobupivacaine. With this background the following study was conducted to evaluate the efficacy of ropivacaine 0.75% for brachial plexus block in upper limb surgeries and its clinical comparison with bupivacaine 0.5%. Aims and Objectives: To assess the efficacy and toxicity of ropivacaine 0.75% and bupivacaine 0.5% as potential agents for brachial plexus block for surgeries of the upper limb around and below the elbow. Settings and Design: prospective, comparative, randomized, single blinded clinical trial. Materials and Methods: After institutional ethical committee approval, 100 patients physical status ASA I & II, of either sex, between 18-60 years, weighing between 40-60 kgs posted for upper limb surgeries around the elbow, forearm and hand were divide into two groups of 50 patients each. Group R (Ropivacaine group) received 0.75% isobaric ropivacaine 30 ml in supraclavicular brachial plexus block. Group B (Bupivacaine group) received 0.5% isobaric bupivacaine 30 ml in supraclavicular brachial plexus block by using peripheral nerve stimulator. Vitals, sensory, motor and analgesia score at pre-defined intervals intra-operatively were noted. Onset of analgesia, sensory & motor blockade, total duration of post-operative pain relief (VAS ≥ 5) and time of demand of first rescue analgesic were also noted along with any intra-operative complications, if any. Statistical Analysis: All the results were expressed as Mean ± SD. Statistical analysis was performed using Unpaired Student’s t-Test. Statistical significance was considered with a p value of ≤ 0.05. Results: Demographic profile and duration of surgery were comparable among the two groups. The mean time of onset of sensory block, onset of motor block and onset of analgesia were significant (p<0.05) in group R as compared to group B. The mean duration of sensory block and duration of post-operative analgesia were comparable between the two groups. However, the mean duration of motor block was significantly lower (p<0.05) in group R as compared to group B. the baseline hemodynamic variables and requirement of first analgesic dose and other adverse events were equivalent in both the group. Conclusion: Ropivacaine when compared with Bupivacaine, has faster onset of analgesia, sensory & motor blockade, significantly lesser duration of motor blockade. Ropivacaine also provides satisfactory post-operative analgesia with a stable hemodynamic profile similar to Bupivacaine with no undue adverse effects.

Brachial plexus block is gaining popularity day by day for upper extremity surgery because it has manifold advantages. Supraclavicular approach offers a high success rate for elbow, forearm, hand surgery. Different mixtures of local anesthetics are intended to provide faster block onset than long-acting agents and to extend the duration typically seen with intermediate or short-acting agents. This prospective, randomized comparative study was conducted to compare the onset time of sensory block, onset time of motor block and time to achieve complete block, duration of analgesia adding fentanyl with bupivacaine-lignocaine mixtures in supraclavicular brachial plexus block. A total of 60 patients fulfilling the inclusion and exclusion criteria were selected for the study & devided into two groups. Group A received lignocaine-bupivacaine mixtures( 1% lignocaine, 0.25% bupivacaine) and was considered control; group Group B received fentanyl (100?g) with the local anaesthetic mixtures( 1% lignocaine, 0.25% bupivacaine). The mean onset of sensory and motor block were significantly early in group B compared with that of group A. The mean time to achieve complete block and duration of analgesia were significantly longer in group B. It was revealed in the study that patients of group B had no pain up to 4 hrs, there was first reporting of pain (VAS >4) around 5 hrs, the worst pain was experienced after 8 hrs, first dose of analgesic was administered according to patient’s request. The patients of group A had no pain up to 3 hrs. Thereafter pain intensity increased at 4 hrs, around 6 hrs postoperatively the patients experienced the worst pain . This feature reveals a significantly longer duration of analgesia in group B. This study revealed that addition of fentanyl significantly causes early onset of anaesthesia and longer duration of analgesia without any side effects.Bangladesh Med J. 2015 Jan; 44 (1): 26-31

Among the various approaches to block brachial plexus , supraclavicular approach offers a high success rate for elbow, forearm and hand surgery . Various adjuvant drugs have been used with local anesthetics in order to decrease the time of onset and prolong the duration and quality of regional blocks. So efforts were made to combine the adjuvant with local anesthetics to improve patient and surgeon satisfaction. In this randomized study we tried to see the effect of verapamil in brachial plexus block as an adjuvant with local anaesthetic .This randomized study wasconducted in Anaesthesiology department of ShaheedZiaurRahman Medical College Hospital after approved by the ethical review board of this hospital.The study subject were divided into two groups (Group A=only local anaesthetics&Group B=local anaesthetics with Verapamil) , 30 IN numbers in each group. Group-A patients was administered 15ml of 1% lignocaine with 15 ml of bupivacaine 0.25% while in Group-B patients was administered injection verapamil 3.5 ml (3.5 mg) in addition to the above mixture. In this study mean onset time of sensory block was 11.53 ± 1.4 minutes in group - A and 7.12 ± 1.68 minutes in group – B which is not statistically significant (p value = 0.057). The mean onset time of motor block in group A was 15.26 ± 1.96 min, and in group B was 11.58 ± 2.68 min and this difierence isstatistically significant (p value=0.000152). Duration of motor block was 96.30 min and 115.08 min in group A and Group B respectively. Sensory block was 157.26 min and 188.0 min in group A and Group B respectively. Regarding the heart rate, no significant difference was detected between the groups at the time of preanesthesia and at the 5 min after anaesthesia. Compared with group B patients, group A patients shows slight but statistically significant increased heart rate at the 10 min (80, 92 beat/min respectively) after brachial plexus block. At 30 minute after, mean systolic BP was 97.9±4.7 mmHg in group A and 84.3±5.0 mmHg in group B. At 45 minute after, mean systolic blood pressure was 94.6±15.6 mmHg and 84.3±5.0 mmHg in group A and group B respectively. At 60 minutes after, mean systolic blood pressure was 59.6±6.0 mmHg in group A and 61.2±9.4 mmHg in group B. At 15, 30 and 45 minute difference was statistically significant (p<0.05) between two groups. In conclusion, the study revealed that verapamil can be used as an adjuvant to decrease the onset time of sensory and motor blocks of bupivacaine in supraclavicular block. Moreover, verapamil doses in regional blocks did not show any hemodynamic side effects. Bangladesh Med J. 2017 May; 46 (2): 43-47

Background The popularity of supraclavicular brachial plexus block in upper limb surgery in recent years are due to better understanding of using adjuvant to local anaesthetics, its advantages and in avoidance of the hazards of general anaesthesia. Objective To compare the quality of anaesthesia and duration of analgesia with clonidine-bupivacaine or fentanyl-bupivacaine in supraclavicular brachial plexus block. Method A total number of 60 patients (ASA class 1 and II) were selected randomly into two groups, thirty in each group. Group-A (control group) received fentanyl (100ìg) 2ml and bupivacaine (0.25%) 38ml, total of 40ml.Group-B (study group) received clonidine (150ìg) 2ml and bupivacaine (0.25%) 38ml, total of 40ml.The parameters including pulse rate, non-invasive systolic and diastolic blood pressure, respiratory rate, SpO2, onset and duration of motor and sensory block, post operative pain score in VAS, duration of analgesia, first analgesic demand, side effects were assessed and recorded. Result Onset and duration of sensory block were significantly higher in group-B than in group-A (P<0.001) and motor block were quite prolonged in group-B than group-A (p<0.001), prevalence of sedation in group-B slightly higher than group-A. But intensity of pain measured by VAS in group-A expressed highest at 8 hours of postoperative period and group-B shows highest VAS at 12 hours. Duration of effective analgesia (time from supraclavicular block to first analgesic demand) in study group-B had significantly longer mean duration than that produced by control group-A (14.4 ± 1.3 vs 10.9 ± 1.5 hours; P<0.001). Conclusion Clonidine and bupivacaine combination is a better alternative to fentanyl and bupivacaine in respect of quality of anaesthesia and duration of analgesia.

BACKGROUND AND AIM:Brachial plexus block is a safe, effective, low-cost anesthesia with good postoperative analgesia. Adjuvants to local anesthetics may enhance the quality and duration of analgesia. The aim of the study was to study the efcacy of a combination of 0.25% bupivacaine alone versus 0.25% bupivacaine and dexmedetomidine in brachial plexus block by supraclavicular approach. METHODS: This is a prospective double-blind study conducted on sixty patients of ASA1 and ASA2 posted for upper limb surgeries, randomized in a double-blind fashion into two groups. Group A (N-30) received 34ml of 0.25% bupivacaine with 0.5ml of distilled water and group B (N-30) received 0.5ml dexmedetomidine (50 μg) with 34ml of 0.25% bupivacaine as supraclavicular brachial plexus block with help of a nerve stimulator. Onset and recovery time of sensory and motor block, duration of analgesia, sedation scores, quality of block, and side effects compared in both groups. RESULTS: Baseline characteristics were well matched in both groups. The intraoperative hemodynamic recording was done at 15 min time intervals from the administration of the drugs. There was a reduction in heart rate, systolic blood pressure, and diastolic blood pressure 30 mins onwards in both groups. There was no signicant difference in the onset of sensory and motor blocks. Duration of sensory block was 299.57 ± 35.94 mins in Group A and 782.2 ± 82.76 mins in Group B, duration of motor block was 272.17 ± 37.31 mins versus 755.63 +/- 86.6 mins respectively, total duration of analgesia was 321 ± 35.46 mins versus 815.80 +/- 88.1 mins respectively. Ramsay sedation score was similar at arrival in both groups but in post-op, the score of 3 was noted in 0% (0/ 30) in Gr A and 93.3% (28/ 30) in Gr B . Quality of analgesia was also better in Group B. There were no signicant adverse events noted in both groups. CONCLUSION: This double-blind Randomized Controlled study showing the combination of dexmedetomidine 50 μg with 34ml of 0.25% bupivacaine is better than 0.5ml of distilled water with 34ml of 0.25% bupivacaine in the duration of sensory and motor block, with better sedation and quality of analgesia with the good safety prole in brachial plexus block by supraclavicular approach.

Purpose: Research is ongoing to determine the lowest dose of local anesthetics in brachial plexus block that provides adequate anesthesia and postoperative analgesia and reduces complications related to local anesthetics. Methods: Patients 18-65 years of age who underwent upper limb surgery and who received ultrasound-guided supraclavicular brachial plexus block at the Erciyes University Faculty of Medicine Hospital between February 2014 and January 2015 were included in the study (n=50). Supraclavicular brachial plexus blocks were performed on Group B cases by adding 30 ml 0.33% bupivacaine and on Group BD cases by adding 15 ml 0.33% bupivacaine and 1 µg / kg dexmedetomidine. Block success was evaluated by the onset and block duration of motor and sensory block and the duration of analgesia. Results: The block success of Group B and Group BD was 92.6% and 89.3%, respectively (P = 1.000). Onset time of sensory block, degree of sensory block, duration of sensory block, onset time of motor block, degree of motor block and duration of motor block were similar in both groups in the intergroup comparison (P > 0.05). Duration of analgesia and the operative conditions of groups were similar (P > 0.05). Conclusions: In the implementation of ultrasound-guided supraclavicular brachial plexus block, block success, sensory and motor block and analgesia duration were similar for patients anaesthetized with 30 ml of bupivacaine in comparison with dexmedetomidine+bupivacaine (when the bupivacaine dose was reduced by 50% by the addition of the adjuvant).

Objectives : To make a comparative evaluation of efficacy of brachial plexus blockade between supraclavicular subclavian perivascular technique and axillary transarterial technique with a tourniquet and also to compare the latency & potency of the block, to ascertain the risks of complications between the techniques and to compare the haemodynamic stability of the patient.Methods : For this purpose a total of 100 undergoing surgery for distal to the midarm. They were randomly selected by odd and even numbering method. These patients were divided into two groups (Group A: subclavian perivascular supraclavicular technique bearing all the odds numbers and Group B: transarterial axillary technique with a tourniquet bearing all the even numbers; fifty patients in each group.Results : The only exception is the mean on set time of sensory block was 11.0±2.6 minutes and 14.3±2.1 minutes in Group A and Group B respectively. The mean on set time of motor block were 18.3±3.9 minutes in Group A and 21.4±3.2 minutes in Group B. So the mean on set time of sensory block and motor block were statistically significant (p<0.05). Most of the patients found complete sensory block and complete motor block between two groups and no significant (p>0.05) difference was found in the present study. Adequate efficacy of block were predominate in both groups and no significant (p>0.05) difference was found. The level of satisfaction of surgeon and it was found that 92.0% in Group A and 94.0% in Group B were satisfied. Patient’s co-operation was found 92.0% and 94.0% in Group A and Group B respectively. No significant (p>0.05) difference were found in terms of surgeon satisfaction and patients cooperation between two groups.Conclusion : It can be concluded that the supraclavicular subclavian perivascular technique and axillary transarterial technique with a tourniquet both are equally effective and safe method for providing brachial plexus block distal to midarm (Lower half of the arm, elbow, forearm and hand).Chatt Maa Shi Hosp Med Coll J; Vol.14 (2); Jul 2015; Page 21-26

In the era of ultrasound-guided regional techniques, we searched for short and potent local anesthetic for patients undergoing ambulatory upper limb procedures. However, studies about articaine efficacy in brachial plexus block are limited. In this study, we compared its safety and efficacy against bupivacaine as a commonly used anesthetic agent for ultrasound-guided supraclavicular brachial plexus block. Methods. This randomized prospective study was performed at Ain Shams University Hospital from January to March 2020. A total of 117 patients aged 20 to 60 years, with the American Society of Anesthesiologists physical status I and II, were enrolled in the study. Patients were randomly allocated into two groups: in group A, patients received 30 ml articaine 2%, and in group B, patients received 30 ml of bupivacaine 0.5%. We measured motor and sensory block duration as a primary outcome. Other secondary outcomes such as onset of block, duration of analgesia, patient satisfaction, and time to home discharge readiness were also measured. Results. We analyzed data collected from 97 patients. The motor block duration was significantly shorter in group A (165.73 ± 20.33 min) than in group B (220.27 ± 37.73 min). The onset of motor block was faster in group A (8.73 ± 4.33 min), and the postoperative VAS score was lower in group B. Patients in group A achieved an earlier home discharge of 289.67 ± 2.73 min. Conclusion. Earlier resolution of articaine block makes it more favorable than bupivacaine for ambulatory surgery. This trial is registered with (NCT04189198).
