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.

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

BACKGROUND Sensory and motor functions of peripheral nerve can be blocked by injecting local anaesthetic around the group of nerves, which will stop the conduction of nerve impulse. Peripheral nerve block is a well-accepted technique in anaesthesia care. Brachial plexus block is also one of the reliable techniques in providing regional anaesthesia for upper limb surgery. METHODS This was a prospective, double blinded, randomised comparative study which included 40 patients of American Society of Anaesthesiologists (ASA) grade I and II of either sex of 20 - 65 years old age groups for upper limb surgery. Cases were divided randomly into two groups: Group A: received levobupivacaine hydrochloride 0.5 % 25 cc with dexmedetomidine injection. Group B: received levobupivacaine hydrochloride 0.5 % 25 cc injection. Each individual was allocated to respective group by computer generated randomisation chart. Both group A and B were assessed for the onset of sensory & motor block, duration of postoperative analgesia and duration of action. RESULTS In the present study, it was observed that the onset of sensory blockade (P < 0.001) & motor blockade (P < 0.001) was earlier in groups A with prolonged duration of sensory & motor blockade (P < 0.001) as compared to group B. Group A took longer time for first rescue analgesia post operatively compared to group B, and the difference was found significant (P < 0.001). Both group A and group B were comparable for systolic blood pressure, diastolic blood pressure, and heart rate. CONCLUSIONS The onset of sensory and motor blockade was early in 0.5 % levobupivacaine with dexmedetomidine with prolonged duration of action and required lesser dose of rescue analgesic in 0.5 % levobupivacaine with dexmedetomidine as compared to 0.5 % levobupivacaine in supraclavicular brachial plexus block.

Background: Brachial plexus block with Bupivacaine provides effective intraoperative anesthesia and analgesia. The use of dexamethasone along with local anesthetic has been shown to improve the duration of analgesia. Objective: To observe the effect of Dexamethasone on the duration of analgesia for Supraclavicular Brachial plexus block. Materials and Methods: A prospective, double-blind study was undertaken in patients scheduled for upper limb surgeries under supraclavicular brachial plexus block. patients were randomly divided into two groups, Group (BD) and B. Group B received 28 ml of 0.25% bupivacaine with 2 ml normal saline while Group BD received 28 ml of 0.25% bupivacain with 2ml (8mg) dexamethasone for supraclavicular brachial plexus block. The groups were compared regarding quality of sensory and motor blockade. All the information was recorded in data collection sheet. Data was processed and analysed with the help of computer program SPSS and Microsoft excel. Results: There was no significant difference between groups in respect of demographic and American Society of Anaesthesiologist (ASA) status. Mean age was found to 34.7±8.53 years. In Group (BD) , 63.3% were ASA I and 36.6% were ASA II. In Group B, 60% were ASA I and 40% were ASA II. It has become evident that satisfactory anaesthesia can be made possible by addition of adjuvant to local anaesthetic in brachial plexus block (in Group-BD). onset of sensory block was faster in Group BD (8.17 ± 1.4 min) than Group B (9.12 ± 1.68 min). Similarly mean onset time of motor block in group A was 12.26 ± 3.96 min, and 11.58 ± 3.68 min in group B. Our study shows that duration of motor block was 408.68±26.96 min and 380.26 ± 24.11 min in group BD and Group B respectively. Conclusion: There was significantly prolonged duration of analgesia in addition of Dexamethasone without any unwanted effects. KYAMC Journal Vol. 11, No.-4, January 2021, Page 199-203

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

Introduction: The objective of this study was to evaluate the effect of 50μg dexmedetomidine on the onset and duration of block and duration of analgesia when used as an adjuvant to bupivacaine in ultrasound guided supraclavicular brachial plexus block. Methods: Eighty patients of ASA physical status I and II undergoing elective upper limb surgery under ultrasound guided supraclavicular brachial plexus block were randomly divided into two groups: Group D and Group B. Group D (n=40) received 19.5 ml of 0.5% bupivacaine with 0.5 ml (50 μg) dexmedetomidine. Group B (n=40) received 19.5 ml of 0.5% bupivacaine with 0.5 ml normal saline. Onset time of sensory and motor block, duration of sensory and motor block and duration of analgesia was recorded. Results: Onset time of sensory block (10.55±4.84 min in Group D vs 12.50 ±5.20 min in Group B) and motor block (15.85±5.9min in Group D vs 18.35±5.6min in Group B) though earlier in Group D as compared to Group B was not statistically significant (p value =.087 for sensory block and p value=.058 for motor block). The duration of sensory block (772.20 ±167.84 min in Group D vs 398.38 ±129.839min in Group B) and motor block (725.63±140.964min in Group D vs 361.88±128.764 min in Group B) was statistically significantly prolonged in Group D (p value= .000 for sensory and p value =.000 for motor block). The Duration of analgesia (845.93±184.545min in Group D vs 430.04±121.307 min in Group B) was also statistically significantly prolonged in group D (p value= .000). Conclusions: Dexmedetomidine (50 μg) as an adjuvant to 0.5% bupivacaine solution in ultrasound guided supraclavicular brachial plexus block prolongs the duration (sensory and motor) of block as well as the duration of analgesia with no effect on the onset time of block.

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).

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.

BACKGROUND Supraclavicular brachial plexus block is a reliable, regional anaesthetic technique for upper limb surgeries. Also known as “spinal of upper limb”.1 The present study was conducted to assess the analgesic efficacy of dexamethasone as an adjuvant to 0.5 % ropivacaine for ultrasound sonography (USG) guided brachial plexus block. METHODS 50 adult patients of American Society of Anaesthesiologists (ASA) physical status I and II of both genders, aged 18 - 50 years scheduled for elective upper limb surgeries under brachial plexus block via supraclavicular approach were randomised into 2 groups of 25 patients each to receive either 20 ml of 0.5 % ropivacaine with 2 ml of normal saline (group A) or 20 ml of 0.5 % ropivacaine with 2 ml of dexamethasone (8 mg) (group B). RESULTS Use of ultrasound helps in better visualisation of nerves, needle & spread of local anaesthetic at brachial plexus block site. So, less amount of drug volume is required for the block. Time of onset of sensory and motor block was significantly lower in group B compared to group A. Mean duration of motor and sensory block was significantly longer in group B than group A. The duration of postoperative analgesia was 18.79 ± 2.31 hours in group B & 9.06 ± 0.35 hours in group A, with statistically highly significant difference (P < 0.05). There were no perioperative haemodynamic variations between the two groups and no complication of technique or adverse effects due to dexamethasone occurred. CONCLUSIONS Dexamethasone 8 mg has significantly extended duration of analgesia of brachial plexus block with no adverse effects.

Abstract Background Post operative pain and stress is a very known complication of many surgical procedures which represents a burden for the patient and associated with many complications including stress, myocardial ischemia, prolonged hospital stay and the need of extensive post operative analgesia. Aim of the Work to study the effect of Fentanyl as an adjuvant to bupivacaine and Lidocaine in supraclavicular brachial plexus block. After taking approval from Local Ethical Committee approval and informed written consent from each patient, this randomized prospective comparative study was conducted on 60 patients who were divided into two groups: Group A (Control group): 20 ml of 0.5% bupivacaine + 6 ml of lidocaine hydrochloride 2% + 1 ml of Normal Saline 0.9%. Group B (Fentanyl group): 20 ml of 0.5% bupivacaine + 6 ml of lidocaine hydrochloride 2% + 1ml of fentanyl 50 ug/ml. Results our study showed that addition of a 50 microgram of fentanyl to bupivacaine and lidocaine in ultrasound-guided supraclavicular nerve block has statistically significant effect on the onset of sensory and motor block and prolonged the duration of the sensory and the motor block. In addition, fentanyl prolonged the duration of analgesia of the plexus block significantly, as proved by the time of request of first analgesia. Moreover, in fentanyl group, postoperative analgesic requirements were greatly lesser than that of bupivacaine and lidocaine groups. Addition of fentanyl also did not affect the hemodynamic to a significant level Conclusion fentanyl with bupivacaine and lidocaine more superior than the use of bupivacaine and lidocaine alone.
