Brachial plexus block is one of the best surgical technique for upper limb surgeries. It is a good anesthetic and analgesic agent. Though levobupivacaine has a duration of action of three to eight hours it has an acceptable analgesic property and few other practical constraints. Addition of vasoconstrictors like α-adrenergic agonists, hyaluronidase, neostigmine, opioids have been found to be effective. Dexmedetomidine, an α2 receptor agonist has found to be a better adjuvant to levobupivacaine by few literatures. To assess the effect of levobupivacaine 0.5% alone and with dexmedetomidine 100 μg as an adjuvant to levobupivacaine 0.5% on the onset and duration of sensory and motor block, the duration of perioperative analgesia, complications and sedation score.This study was conducted after ethical committee clearance in a tertiary care medical college hospital in northern Kerala, India. 60 patients between the age of 18 and 60 years planned for upper limb surgery under brachial plexus block, who fulfilled the inclusion and exclusion criteria were included in the study. A pre anesthetic checkup was done to assess the patient before including in the study. The patients who were included in the study were randomly assigned into two groups – one group received 1 ml (100µg) dexmedetomidine with 39 ml of 0.5% Levobupivacaine(LD group) and the second group received 1 ml of 0.9% normal saline and 39 ml of 0.5% Levobupivacaine(LS group) as anesthetic agent through sealed envelope technique. The clinical history, vitals and hemodynamic parameters were monitored and noted prior to and during the surgery. The data collected was analyzed and tabulated. There was no statistically significant difference between both groups with respect to age, Gender and weight signifying proper random allocation of study subjects. None in LD group required post operative analgesia. The mean duration of onset of sensory and motor block was earlier and duration of motor and sensory analgesia was prolonged with the addition of Dexmedetomidine to Levobupivacaine. The hemodynamic stability was better with Dexmedetomidine. Bradycardia was reported in 20% of study participants who were administered dexmedetomidine Dexmedetomidine added to levobupivacaine provides better anesthetic and analgesic care in upper limb surgeries done using brachial plexus block.

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: In peripheral nerve blocks, adjuvants are added to local anaesthetics to improve the quality of anaesthesia and analgesia. We designed this randomized single blinded prospective study to compare the analgesic efficacy of tramadol used as an adjuvant to bupivacaine for supraclavicular brachial plexus block in patients undergoing orthopaedic surgeries of upper limb.Aim of study: In this study, we aimed to compare onset, duration and quality of analgesia along with respiratory, hemodynamic changes with tramadol as adjuvant to bupivacaine in supraclavicular brachial plexus block in the patients undergoing upper limb surgery.Method: In this prospective randomized control trial, two groups of 30 patients each were investigated. 28 ml. of 0.5% bupivacaine (plain) with 2 ml. normal saline was administered in group - I and 28 ml. of 0.5% bupivacaine (plain) with 2ml. (100 mg.) tramadol was administered in group - II. The onset of sensory and motor block, duration of analgesia, respiratory/hemodynamic parameters and post-operatively quality of analgesia via visual analogue scale were assessed.Results: The duration and quality of analgesia was significantly increased by adding tramadol in bupivacaine than bupivacaine alone (p=<0.001 and <0.001) whereas there was no statistically significant difference in onset of motor (p=>0.35) and sensory block (p=>0.75) and also hemodynamic and respiratory parameters.(HR p=>0.1, MAP p=>0.5, and SPO p=>0.5).Conclusion: The study suggests that tramadol when added to bupivacaine 2 for supraclavicular brachial plexus block enhances the quality of anaesthesia and analgesia without affecting respiratory/hemodynamic parameters.JNGMC Vol. 13 No. 2 December 2015, Page: 13-16

 Supraclavicular brachial plexus block is among foremost technique of regional anaesthesia administered during upper-limb surgery. Different adjuvants have been used with varied results for prolonging the sensory and motor blockade. Dexamethasone and Clonidine have been established as suitable adjuvants for blocks. Adding adjuvants to local anaesthetic drugs in nerve blocks has many benefits. We studied performance of dexamethasone or clonidine as additives to local anaesthetic in subclavian perivascular block as a part of upper limb surgery. Aim was to ascertain which of them is a better adjuvant. Study population was randomized to 2 groups of 50 patients each. Group 1 was given 5 ml of 2% lignocaine and 15 ml 0.5% bupivacaine with 8mg dexamethasone. Group 2 received 5ml 2% lignocaine and 15 ml 0.5% bupivacaine with 0.150 mg clonidine. Time to establishment of sensory & motor block, duration of analgesia and any adverse effects were observed. Statistical analysis was done with SPSS 13.0. Quantitative variables were assessed using student t test. Qualitative variables were analysed using Chi square test. P value &#60; 0.05 was defined as significant. Onset of sensory blockade was at 7.23+4.24 in group 1 and 8.36+2.68 minutes in Group 2. Average time to motor block was at 8.48+3.22 minutes in Group 1 and 9.58+3.71 minutes in Group 2. Analgesia’s duration in Group 1 and Group 2 was 998.2+338.5 and 879.3+284.5 minutes respectively. No major adverse events were seen in either group. Performance of dexamethasone was similar to clonidine as adjunct to local anaesthetic in subclavian perivascular approach of brachial plexus block. However, it has faster sensory and motor blockade’s onset. Analgesia’s duration observed was found to be longer, though the difference was statistically insignificant.

Purpose: This prospective study is to compare the supraclavicular and infraclavicular approaches of brachial plexus block for upper limb surgery using 0.05mg of dexmedetomidine and 30ml of 0.5% ropivacaine. Method:  This prospective, randomized controlled trial was conducted at Govt. Medical College, Rajindra Hospital, Patiala on sixty patients in two groups (group S and group I) of 30 each of 18 to 65 yrs of age of either sex of ASA grade I or II scheduled for upper limb surgery. In both supraclavicular and infraclavicular approach the drug injected was 30ml of 0.5% ropivacaine and 0.05mg of dexmedetomidine. Result: We found that in patients with comparable demographic parameters there was no statistically significant difference in hemodynamic parameters, onset and duration of sensory and motor block, duration of analgesia and patient satisfaction score between the groups. There was no statistically significant difference in the quality of block in either group. No episode of pneumothorax, Horner’s syndrome or local anaesthesia toxicity occurred in any of the group. Accidental vascular puncture occurred in four out of thirty patients in supraclavicular group and none in infraclavicular group. Conclusion: This study concluded that infraclavicular approach is more safe than supraclavicular approach in upper limb surgeries (elbow proximally to hand distally).

INTRODUCTION Brachial plexus block is a regional anesthesia technique that is sometimes employed as an alternative or as an adjunct to general anesthesia for surgery of the upper extremity. This technique involves the injection of local anesthetic agents in close proximity to the brachial plexus, temporarily blocking the sensation and ability to move the upper extremity. OBJECTIVES To compare time of onset and duration of sensory and motor block between two groups. To compare peri-operative and post-operative analgesia between two groups MATERIAL AND METHOD Orthopaedic operation theatre, post-anaesthesia care unit, orthopaedic post- operative ward of Nil Ratan Sircar Medical College and Hospital. All the ASA physical status I and II patients of either sex, age between 18-60 years undergoing upper limb orthopaedic surgery under supraclavicular brachial plexus block. CONCLUSION Addition of Dexmedetomidine to ropivacaine in supraclavicular brachial plexus block significantly prolongs the duration of analgesia and motor block in patients undergoing upper limb surgeries and is a remarkably safe and cost effective method of providing post-operative analgesia.

Objective: To investigate the effectiveness of ropivacaine in supraclavicular brachial plexus block by nalbuphine and compare it to ropivacaine alone. Study Design: Randomized controlled trial Place and Duration of Study: Department of Anaesthesia, Fatima Memorial Hospital/College of Medicine & Dentistry, Lahore from 1st June 2020 to 31st March 2021. Methods: Ninety six patients of both genders with ages 20 to 65 years undergoing upper limb surgical procedure electively were included. All the patients were divided equally in to two groups, each group consist of 48 patients. Group A treated with ropivacaine with nalbuphine and group B treated with ropivacaine normal saline. Effectiveness between both groups was examined. Results: No significant difference was observed regarding age, gender, body mass index and ASA class I/II between both groups with p-value >0.05.A significant difference was found regarding onset time of sensory and motor block between both groups (p=0.001). Mean sensory block duration in group A was more 425.18±17.82 minutes as compared to group B 254.43±20.44 minutes. Mean duration of motor block was also more in group A 418.65±20.84 minutes as compared to group B 226.15±12.52 minutes. Duration of analgesia was high in group A as compared to group B with p-value <0.05. Conclusion: In supraclavicular brachial plexus block 0.75% with 10mg of nalbuphine is particularly effective in sensory, motor, and analgesic periods in relation to ropivacaine alone.

BACKGROUND To improve the time of regional anaesthesia many methods have been used. Epinephrine continues to be the most commonly used drug for this purpose. We wanted to compare the effects of alpha-adrenergic agonists clonidine and adrenaline as an adjuvant to ropivacaine in blocking brachial plexus by the supraclavicular approach in patients undergoing upper limb surgeries. METHODS It is a prospective randomised comparative study conducted for 18 months in 40 patients randomly divided into group RA and group RC, conducted on American Society of Anesthesiology (ASA) I and II patients undergoing upper limb surgeries under supraclavicular brachial plexus block. In group RA 30 mL of 0.5 % ropivacaine with 5 microgram / mL of epinephrine was given and in group RC 30 mL of 0.5 % ropivacaine with 1 microgram / Kg of clonidine was given. RESULTS On comparing effects of added alpha-adrenergic agonists clonidine and epinephrine to ropivacaine for supraclavicular brachial plexus block, it was found that there was no significant difference in the onset of the sensory blockade and motor blockade in the two groups. Duration of sensory blockade was significantly more in the clonidine with ropivacaine group when compared with the epinephrine and ropivacaine. There was no significant difference in haemodynamic responses between the two groups. CONCLUSIONS Supraclavicular approach brachial plexus block is effective in terms of cost and performance, and the margin of safety along with good postoperative analgesia. Hence, it can be concluded that the addition of 1 µg / Kg of clonidine to 0.5 % ropivacaine in supraclavicular brachial plexus block provides a longer duration of analgesia as compared to 5 µg / mL of epinephrine added to 0.5 % ropivacaine.
