Background: Ultrasound guided brachial plexus block is the preferred technique for surgeries on upper limb. Adjuvants are usually added to peripheral nerve blocks to increase their analgesic efficiency and duration. We compared analgesic effects of dexmedetomidine 1mcg/kg and clonidine 1mcg/kg as adjuvant to a low volume of bupivacaine in USG guided supraclavicular brachial plexus block.Methods: A prospective, randomized controlled, double blind study planned after permission from institutional ethics committee. Sixty ASA grade I, II patients, 18-60 years undergoing upper limb orthopedic surgery included. Group 1 (Control group) received 20 ml of 0.25% bupivacaine. Group 2 (Dexmedetomidine group) received 20ml of bupivacaine + dexmedetomidine (10 ml of 0.5% bupivacaine + 1µg/kg of dexmedetomidine, diluted with 0.9% NS to 20 ml) Group 3 (Clonidine group) received 20 ml of 0.25 bupivacaine + clonidine (10ml of 0.5% bupivacaine+1µ g/kg of clonidine, diluted with 0.9% NS to 20 ml) in USG guided supraclavicular brachial plexus block. Continuous variables analyzed with analysis of variance or Kruskal-Wallis test and categorical variables with Fisher’s exact test.Results: Pain free period was 864.90±357.16 minutes: dexmedetomidine group; 584.59±172.38 minutes: clonidine group, 431.78±138.40 minutes: control group with p< 0.001. VRS (verbal rating score) was significantly higher in control group as compared to dexmedetomidine at 4 hours but the pain scores were comparable between all the groups after 8 hours of block.Conclusions: Dexmedetomidine as an adjuvant to bupivacaine provides prolonged anaesthesia, better pain relief in early postoperative period with haemodynamically stable, calm patients compared to clonidine and control group.

BACKGROUND : Supraclavicular approach to brachial plexus block is a versatile and reliable regional anesthesia technique and a suitable alternative to general anesthesia for upper limb surgical procedures. Ropivacaine , a long acting local anesthetic, with less tendency for neurotoxicity and cardiotoxicity is a great local anesthetic for the procedure. Use of adjuvant Dexmedetomidine , a potent alpha 2 adrenoreceptor agonist improves the quality of anesthesia as well as intra-operative and post-operative analgesia while maintaining haemodynamic stability, arousable sedation and mild respiratory depression. MATERIALS AND METHODS: Eighty patients aged between 18 and 60 years with ASA grade I or II posted for elective upper limb surgeries were included in the study and were randomly divided into 2 groups with forty patients in each. Group A received 0.5% ropivacaine (31 mL) and Group B received 0.5% ropivacaine + dexmedetomidine 1microgram/kg (31mL). Both groups were compared for onset time and duration of sensory blockade, onset time and duration of motor blockade , total duration of analgesia and associated side effects. CONCLUSION : Dexmedetomidine as an adjuvant to ropivacaine in the supraclavicular brachial plexus block for upper limb surgeries , significantly shortens the onset time and prolongs the duration of sensory and motor blocks, with longer duration of post-operative analgesia , with associated significant sedation and a few manageable side effects like bradycardia and hypotension.

Background: Comparative study of intravenous versus perineural administration of dexmedetomidine in supraclavicular brachial plexus block using 0.75% ropivacaine by ultrasound guided technique in upper limb surgeries.Methods: Patients in the age group 18-58 years both male and female, having ASA 1 and ASA 2, scheduled for elective surgery of unilateral upper limb surgeries were included and randomly divided into three groups’ i.e. group RD, group RDI and group R and patients with chronic pain or taking any analgesics, ASA grade III and IV, bleeding disorders, history of brachial plexus injury, known allergy to the study drug, previous shoulder surgery, any psychiatric disorders, peripheral neuropathy, failed block, significant respiratory disease, hearing impairment, pregnant women, study were excluded.Results: Time to sensory onset in group RD was as compared to group RDI and group R was found statistically significant (p<0.001). Duration of sensory block (analgesia) in group RD, group RDI and Group R was also statistically significant (p<0.001). The level of sedation of Group RDI and Group RD had highly significant value till 30 mins (p<0.001).Conclusions: The central effects of dexmedetomidine also play some role in prolongation of sensory and motor block duration, as explained previously.

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.
