:Bupivacaine is an amide local anesthetic, available as a racemic mixture of Dextro and Levorotatory Isomers. Due to its rapid onset and longer duration of anesthesia, It is routinely preferred in various regional anesthetic techniques. However, it is associated with serious cardiovascular and neurological toxicity. Its pure S- enantiomer, Levobupivacaine having similar pharmacological profile is known to have lesser cardiovascular and CNS toxicity. Combining adjuvants like clonidine, a centrally acting partial alpha-2-adrenergic agonist to improve quality of anesthesia is common practice. Hence, the aim of our study is to compare efficacy and safety of 0.25% Levobupivacaine and 0.25% Bupivacaine when combined with clonidine in supraclavicular brachial plexus block for upper limb surgeries.Eighty patients aged between 18 to 60 years with ASA physical status I-II, scheduled for elective upper limb surgeries under were randomized into two groups. Peripheral nerve stimulator guided Supraclavicular brachial plexus block was administered. Group BC received 30ml of 0.25% Bupivacaine plus 1µg/kg Clonidine and Group LC 30ml of 0.25% Levobupivacaine plus 1µg/kg Clonidine. The time of onset of sensory and motor block, duration of sensory and motor block, perioperative hemodynamic parameters, postoperative pain for 24hours and adverse effects were studies.Group LC had faster onset of sensory block (p= 0.014) as well as faster onset of motor block (p= 0.012) compared to group BC. However, durations of sensory block and motor block were statistically not significant in both the groups (p>0.05). Perioperative hemodynamic parameters and assessment of pain during 24 hours of post operative period were comparable and statistically not significant.1mcg/kg of clonidine used as an adjuvant to 30ml of 0.25% Levobupivacaine produces faster onset of sensory and motor block compared to 0.25% Bupivacaine in supraclavicular brachial plexus block. However, similar anesthetic efficacy in terms of duration of sensory and motor block, hemodynamics and postoperative analgesia were observed.

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: Supraclavicular brachial plexus block is a good alternative to general anesthesia in surgeries of elbow, forearm, wrist and hand. The aim of this study was to assess the effect of dexamethasone as an adjuvant with bupivacaine in supraclavicular brachial plexus block in upper limb surgeries.Methods: This study was carried out on 60 adult patients of both sexes planned for upper limb surgery during the period from May 2015 to Jan 2016 after approval by the institutional Ethical Committee. Inclusion criteria were American Society of Anesthesiologists physical Status I-II and age between 18 and 50 years. Patients were randomly allocated to two groups of 30 patients each [group I (bupivacaine alone) and group II (bupivacaine + dexamethasone)]. Group I received 30ml of 0.5% bupivacaine with 2ml normal saline while group II received 30ml of 0.5% bupivacaine with 2ml (8mg) dexamethasone for supraclavicular brachial plexus block. Statistical analysis was performed with SPSS for Windows (SPSS Inc., Chicago, IL, USA), version 16.0. For analysis of demographic data and comparison of groups, χ2, unpaired Student's t-test and Mann-Whitney U-test were performed. Power of significance p-value of <0.05 was considered to be statistically significant. We evaluated onset, quality and duration of sensory and motor block along with side effects if any.Results: The mean onset of sensory and motor block in Group I and II was statistically insignificant. The duration of motor and sensory block was significantly prolonged in Group II than in Group I. There were no statistically and clinically significant differences in respiratory and hemodynamic parameters.Conclusions: We conclude that dexamethasone as an adjuvant in supraclavicular brachial plexus block prolongs the duration of motor and sensory block with insignificant side effects.

BACKGROUND To improve the quality of block (sensory and motor characteristics), postoperative pain management and reduce large doses of local anaesthetics, various adjuvants are used with local anaesthetic agents. We have evaluated dexmedetomidine as an adjuvant to 0.5 % ropivacaine in supraclavicular brachial plexus block in terms of onset and duration of sensory and motor block & duration of postoperative analgesia. METHODS This is a prospective randomised comparative study. 60 patients who were admitted for elective surgeries of the lower arm, at the level of elbow, forearm & hand were enrolled. They were divided in to two groups of 30 patients each as follows - group RD: supraclavicular brachial plexus block given with 30 mL of 0.5 % ropivacaine + 1 mL (100 μg) of dexmedetomidine. Group RC: supraclavicular brachial plexus block given with 30 mL of 0.5 % ropivacaine + 1 mL of normal saline. Various parameters like onset times and durations of sensory and motor block, duration of analgesia, total analgesic needed, and side-effects were recorded for each patient. RESULTS The time of onset of sensory and motor block was significantly early in dexmedetomidine group than in control group. The duration of sensory and motor block was significantly prolonged in group RD as compared to group RC. The duration of sensory block was 724.18 + 73.26 min in group RD (GD) and 582.16 + 93.12 min. in group RC (GC). The duration of analgesia was significantly prolonged in group RD. CONCLUSIONS Addition of dexmedetomidine as an adjuvant to ropivacaine is associated with early onset of sensory and motor block. The duration of sensory and motor block was prolonged. The duration of analgesia was prolonged and patients required less rescue analgesia. The use of dexmedetomidine was associated with reversible bradycardia and sedation score was less KEYWORDS Ropivacaine, Dexmedetomidine, Adjuvant, Supraclavicular Brachial Plexus Block

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.

EVALUATION OF SOME CORRELATIVE FACTORS AFFECTING TO BRACHIAL PLEXUS BLOCK IN UPPER LIMB SURGERIES Objective: To assess correlations between age and onset sensory block, age and duration of sensory block, the procedure time and BMI. As well as evaluating the degree of sensory and motor blockade. Subjects and methods: 120 patients underwent upper limb surgery in Hue Central Hospital from 5/2017 to 6/2018. Patients were divided into two groups, group I was 60 patients undergoing ultrasound-guided supraclavicular brachial plexus block, group II was 60 patients with nerve stimulor technique. Each group received 25ml levobupivacaine 0.5% and 1 / 200,000 adrenalin. Results: There were the strong positive correlation between the procedure time and BMI, age and duration of sensory block. There was an inverse correlation between age and onset sensory block. The procedure time was 9,82 ± 4,55 minutes in group I and 14,73 ± 4,73 minutes in group II (p < 0,05). The onset of sensory and motor block was 6,15 ± 1,60 minutes and 7,95 ± 1,05 minutes in group I and 9,92 ± 2,88 minutes and 12,63 ± 2,15 minutes respectively in group II (p < 0,05). The duration of sensory and motor block was 481,38± 116,66 minutes and 412,97 ± 107,32 minutes for group I and 319,22 ± 143,14 minutes and 205,88 ± 48,96 minutes respectively in group II. Conclusion: The procedure time and BMI, age and duration of sensory block, age and onset sensory block, all of them were strongly correlated. Ultrasound guidance for supraclavicular brachial plexus blockade provides a block that was faster in onset, longer duration of block. Key words: brachial plexus block, upper limb surgeries

Background: Huge volumes of local anaesthetics used in conventional blocks may be associated with complications. Hyaluronidase is an enzyme that hydrolyses hyaluronic acid in the tissue. It has been shown to aid the spread of local anaesthetics (LA) through tissue. The aim of this study was to compare between the addition of morphine or hyaluronidase to local anaesthetic in sonar guided supraclavicular brachial plexus block regarding the onset and duration of the block, postoperative analgesia and the total analgesic requirements in the first 24 hours. Patient and methods: Seventy-five patients of American Society of Anaesthesiologists (ASA) physical status I & II, aged 18-60 years, scheduled to acute or elective elbow, forearm or hand surgery under sonar guided supraclavicular brachial plexus block at Tanta University Hospital were randomly allocated into three equal groups; Group I (Control group) received 20 ml containing 9 ml bupivacaine 0.5% and 9 ml lidocaine 2% plus 2 ml normal saline, group II (Morphine group) received 20 ml containing 9 ml bupivacaine 0.5% and 9 ml lidocaine 2% plus 5 mg morphine in 2 ml normal saline and group III (Hyaluronidase group) received 20 ml containing 9 ml bupivacaine 0.5% and 9 ml lidocaine 2% plus 1500 units of hyaluronidase in 2 ml normal saline. The onset of sensory and motor block, duration of sensory and motor block, postoperative VAS, time to first rescue analgesia, total morphine consumption and possible side effects were recorded. Results: Onset of the sensory block and motor block was significantly shorter in the hyaluronidase group than control group and morphine group. Duration of the sensory block and motor block was significantly prolonged in morphine group than hyaluronidase group & control group. VAS started to increase at 6 hours in the control group, at 10 hours in morphine group and at 8 hours in hyaluronidase group. Time to first rescue analgesia was significantly prolonged in morphine group than control group and hyaluronidase group. Total analgesic consumption of morphine was significantly lower in morphine group than control group and hyaluronidase group. Conclusion: Morphine was superior to hyaluronidase as regarding to improving the post-operative pain. The incidence of complications was nil and self-limited in the three groups.

Background: Brachial plexus block is often used either as an adjuvant to general anesthesia (GA) or as a sole anesthesia modality. Supraclavicular brachial plexus block is preferred for its rapid onset, reliable anesthesia and as a safe technique for any surgery in the upper extremity that does not involve the shoulder. We have attempted to undertake this study to compare the haemodynamic, sensory and motor effects of the anaesthetic effect of Ropivacaine alone and Ropivacaine along with Dexamethasone in Supraclavicular Brachial Block in upper limb surgery.Methods: The total duration of surgery was also comparable in both groups. The onset of the sensory and the motor block in bother the groups were similar to each other with no statistical difference, but there was a very high significance in the duration of both sensory and motor block within both the groups.Results: The total duration of surgery was also comparable in both groups. The onset of the sensory and the motor block in bother the groups were similar to each other with no statistical difference, but there was a very high significance in the duration of both sensory and motor block within both the groups.Conclusions: Dexamethasone added to ropivacaine in supraclavicular brachial block for upper limb surgery significantly shortens the onset time and prolongs the duration of sensory and motor blocks without producing sedation in patients.
