Introduction: Brachial plexus blockade at the supraclavicular level delivers an excellent regional anaesthetic technique with unmatched effectiveness for upper limb surgeries. Levobupivacaine, a safer alternative to the commonly used bupivacaine for regional anaesthesia and addition of α2-agonists like dexmedetomidine further improves the quality of regional anaesthesia. Aim: To evaluate the efficacy of levobupivacaine in combination with dexmedetomidine for supraclavicular brachial plexus block. Materials and Methods: This randomised controlled study enrolled 50 American Society of Anaesthesiologist (ASA) grade I and II patients aged between 18-60 years posted for elective upper limb surgeries. Randomisation was done and the patients were divided into two groups with 25 each, to receive either 39 mL of 0.5% levobupivacaine and 100 μgs (1 mL) of dexmedetomidine in group LD (Levobupivacaine with Dexmedetomidine) and 39 mL of 0.5% levobupivacaine and 1 mL of normal saline in group LS (Levobupivacaine with Saline). The onset and duration of sensory and motor blockade along with duration of analgesia were observed. All Quantitative data were compared and analysed using student’s unpaired t test while qualitative data were analysed using Chi-square test. A p-value of less than 0.05 was considered to be statistically significant. Results: The onset of sensory and motor blockade in group LD was significantly faster when compared to group LS (p<0.001). group LD had a longer mean duration of sensory and motor blockade along with duration of analgesia when compared to group LS (p<0.001). There was a better hemodynamic stability in group LD when compared to group LS. Conclusion: Dexmedetomidine added to levobupivacaine provides significantly shorter onset times, greatly prolongs the duration of sensory and motor blockade along with duration of analgesia without any systemic side effects.

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.

Background: The supraclavicular brachial plexus block has proven to be an important, safer and effective alternative to general anaesthesia in surgeries of upper extremity. Primary aim is to study the effect of addition of dexamethasone to levobupivacaine on postoperative analgesia and secondary objectives are to study onset, peak effect and duration of sensory and motor block in brachial plexus blockade in adult patients posted for upper limb surgeriesMethods: This prospective randomized clinical study was conducted on 60 patients of age 18 to 60 years posted for upper limb surgeries. They were randomly allocated into two groups of 30. In Control group LS (n=30) received Inj. Levobupivacaine 30ml and Inj. Normal saline 2ml. In Study group LD (n=30) received Inj. Levobupivacaine 30ml and Inj. Dexamethasone 2ml (8mg).Results: Both the groups were demographically comparable. Onset of sensory block and motor block in group LD and in group LS were similar (p>0.05). Mean duration of sensory and motor block in group LD was higher than in group LS (<0.001). Duration of postoperative analgesia was 21.20±3.23 hours in group LD and 10.24±1.57 hours in group LS (p<0.001).Conclusions: Dexamethasone added to levobupivacaine for brachial plexus block prolonged the duration of sensory, motor blockade and postoperative analgesia but did not alter the onset time, peak effect time of sensory and motor blockade.

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.

BACKGROUND Regional anaesthesia has multiple advantages as compared to general anaesthesia for upper limb surgeries. Here in this study, we wanted to compare bupivacaine 0.5 %, commonly used anaesthetic with ropivacaine 0.75 % which has fewer side effects like cardiotoxicity for supraclavicular brachial plexus block. METHODS A study was performed on 60 ASA I & II patients aged between 18 and 75 years, undergoing upper limb elective surgeries under brachial plexus block using nerve locator. Beginning of sensory and motor block, general nature of block, and terms of sensory and motor blocks were assessed in the C5 to T1 dermatomes. RESULTS There was no statistically significant difference in the onset of sensory and motor blockade between ropivacaine 0.75 % and bupivacaine 0.5 %. Ropivacaine 0.75 % produced similar quality of motor and sensory blockade compared to 0.5 % bupivacaine. The time taken for maximum motor blockade with ropivacaine was comparable with that of bupivacaine 0.5 %. There was no statistically significant difference regarding the duration of analgesia with ropivacaine 0.75 % compared to bupivacaine 0.5 %. Duration of motor blockade with 0.75 % ropivacaine was comparable to that of 0.5 % bupivacaine. CONCLUSIONS Ropivacaine 0.75 % 0.4 ml / kg or 0.5 % bupivacaine 0.4 ml / kg for supraclavicular brachial plexus block produces satisfactory and comparable sensory and motor blockade. It is suggested that lower cardiovascular toxicity of ropivacaine with equal efficacy as bupivacaine in such circumstances may help in reducing the risks to the patient.
