Background: Spinal anesthesia with bupivacaine is administered routinely for lower abdominal and lower limb surgeries. The ensuing nerve block is sufficient to ensure patient’s well being, while motor block facilitates the surgeon’s work. In patients receiving spinal anaesthesia, with local anesthetic agents like bupivacaine, the addition of another drug as adjuvant prolongs the analgesia. The present study is designed to study the effect of dexmedetomidine (D) and Clonidine (C) on the duration of motor and sensory block as well as postoperative analgesia by intrathecal bupivacaine in patients undergoing lower limb orthopedic surgery. Subjects and Methods: This study was carried out on 90 patients in the age group of 18 to 50 years, belonging to the American Society of Anesthesiologists(ASA) physical status I and II presenting for lower limb orthopedic surgery were included in the study. Patients were divided randomly into 3 groups. Group D received 1μg kg-1of dexmedetomidine, group C received 2 μg kg-1 of clonidine and group NS Control group received an equivalent amount of normal saline. Results: From the current study we observed that single dose of 1 μg kg-1 dexmedetomidine over 20 minutes started 20 minutes after spinal block and a single dose of 2 μg kg-1 Clonidine resulted in a significant prolongation of time to two-segment regression, postoperative analgesia,  sensory block and motor block with the maintenance of hemodynamic parameters. Intravenous dexmedetomidine was more effective than Clonidine at the prolongation of time to two-segment regression, postoperative analgesia, sensory block and motor block of spinal anesthesia with 0.5% hyperbaric bupivacaine. Conclusion:  Dexmedetomidine (1μg kg-1) in comparison to Clonidine (2 μg kg-1) and placebo is far more effective in the motor blockade, sensory blockade and duration of postoperative analgesia.

Background: Present study was designed to evaluate the effect of intravenous dexmedetomidine on haemodynamics, sedation and quality of spinal anaesthesia with 0.5% hyperbaric bupivacaine.Methods: Sixty ASA grade 1 and 2, 18-60 years aged patients scheduled for elective lower limb surgeries were randomly divided into two groups: Group C (Control) and Group D (Study), received intravenous normal saline 10ml and intravenous dexmedetomidine 1μg/kg in dilution of 10ml respectively over 10minutes duration, 10minutes before subarachnoid block with 2.5ml of 0.5% hyperbaric bupivacaine. The heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), quality of sensory and motor block and level of sedation were monitored intraoperatively and postoperatively.Results: The heart rate was statistically significantly decreased in group D both intraoperatively and postoperatively. Intraoperative and postoperative SBP and DBP were lower in dexmedetomidine group but clinically that was insignificant. Intraoperative Ramsay sedation scores were significantly higher in dexmedetomidine group (3.49±0.240) as compared to control group (2.51±0.249) (p<0.001) but the patients were easily arousable. The duration of sensory blockade (208.83±9.53 min vs 162.83±9.62 min), duration for 2 dermatomal regression of sensory blockade (146.5±10.013min vs 98±8.57min) and the duration for motor block regression to Modified Bromage scale 0 (167.33±10.5min vs 137.83±11.94min) were significantly prolonged in dexmedetomidine group as compared to control group. The highest level of sensory blockade was also significantly higher in dexmedetomidine group (T6.90±0.759 vs T7.60±0.621). There was no difference in the time for attaining highest level of sensory blockade, time taken for motor blockade to reach Modified Bromage Scale 3 between both the groups. Average 24hr mean VAS score was significantly lower in dexmedetomidine group (1.37±0.15 vs1.72±0.17, p<0.001). Time to first request for rescue analgesic was also significantly longer in dexmedetomidine group (mean 174.33min vs 143.5min). Average 24hour consumption of tramadol analgesic was significantly higher in control group as compared to dexmedetomidine group (391.86±111.62mg vs 279.86±80.55mg, p<0.001).Conclusions: Intravenous dexmedetomidine significantly prolongs the duration of sensory and motor block of bupivacaine spinal anaesthesia. It provides excellent sedation and analgesia. Dexmedetomidine induced decrease in heart rate, systolic/diastolic blood pressure are not clinically significant.

The aim: To compare the different doses of dexmedetomidine as adjuvant to lidocaine in intravenous regional anesthesia. Materials and methods: Ninety patients participated in this study in Al-Yarmook teaching hospital in period between January 1st 2016 – July 1st 2016, divided randomly in to 3 groups. Group 1: received lidocaine diluted with normal saline; Group 2 – lidocaine with dexmedetomidine 0.5 μg/kg; Group3 -lidocaine with dexmedetomidine 1 μg/kg. Statistical analysis was done by IBM SPSS program version 20 and Microsoft excel version 2010 , the means were compared by ANOVA methods and Dunnett t3, significancebetween groups were recorded if p value less than 0.05. Results: Dexmedetomidine was effective in decreasing the sensory block onset time and motor block onset time and prolongation of the motor and sensory recovery with no significant hemodynamic changes than is often shown by the lidocaine alone, it also prolongs the time interval for analgesic requirement after the operation. For the group 3 it was faster than in group 2 and faster than in group 1 significantly (p value < 0.001) to form a sensory block onset and motor block onset; and it took significantly more time to recover the sensation than in group 1 (p value <0.001) and 2 (p value <0.002) , and more time for motor recovery than in group 1 (p value < 0.001). Group 3 had the longest time to call for the analgesia after operation than group 2 and 3 (p value < 0.001); and group 2 also had longer time for the same process than group 1 (p value < 0.001). Conclusions: A variety of adjuvants have been used in IVRA to decrease tourniquet pain, improve block quality, and prolong analgesia after cuff deflation. Opioids are relatively ineffective and cause nausea, vomiting, and dizziness after tourniquet deflation, but several NSAIDs have been shown to be beneficial, dexmedetomidine improves block quality and postoperative analgesia.

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 widespread use of ultrasonography in peripheral nerve blocks requires an assistant. Pappin et al. described the “Jedi grip” technique in which the practitioner works alone by controlling the ultrasound prob with one hand and the needle and injector with the other. In this study, we aimed to compare the block characteristics of the “Jedi grip” technique with the classical technique that performed with an assistant. Methods: 78 patients were included in our study. They were randomly divided into two groups (Group I: Jedi grip and Group II: Classical grip technique). Local anesthetic was applied to both groups from 10 ml of 0.5% bupivacaine +10 ml of 2% prilocaine mixture. The block characteristics were evaluated and recorded every 5 minutes for the first 30 minutes after each block. When the sensory block score was 7 and the total score was 14 or above, the block was considered successful, and the patient was ready for surgery. Results: There was no significant difference between the groups in terms of block characteristics such as block pain, number of attempts, arterial puncture, sensory and motor block onset and regression times, time to be ready for surgery, tourniquet pain, use of additional anesthesia method, use of postoperative analgesia. The duration of block application was 158±47 sec in the Jedi group and 121±83 sec in the control group. Conclusion: The Jedi grip technique has been found to be applicable with the same confidence compared to the classical method in terms of block success and complications.

Purpose: Articaine is used as a local anesthetic for outpatient surgery because it offers rapid onset of anesthesia and short duration motor block. Levobupivacaine is often preferred for Caesarean section. We evaluated the anesthetic characteristics of fentanyl-supplemented plain articaine and levobupivacaine for Caesarean section under combine spinal epidural anesthesia. Methods: Patients undergoing Caesarean section received in random order plain articaine 40 mg (Group A, n=50) or plain levobupivacaine 10 mg (Group L, n=50) mixed with fentanyl 20 µg intrathecally. The onset and duration of sensory and motor block, first analgesic request, and hemodynamic parameters were recorded. Results: Onset times of maximum motor block were longer in Group L than Group A (P=0,001). Time to two-segment regression of sensory block were 70 min for Group A and 90 min group L (P=0.001). Times to complete regression of motor blockade were significantly longer in group L than group A (P =0,001). Conclusion: To have a faster onset and shorter duration of spinal anesthesia, we recommend the use of plain articaine for Caesarean section.

Background The popularity of supraclavicular brachial plexus block in upper limb surgery in recent years are due to better understanding of using adjuvant to local anaesthetics, its advantages and in avoidance of the hazards of general anaesthesia. Objective To compare the quality of anaesthesia and duration of analgesia with clonidine-bupivacaine or fentanyl-bupivacaine in supraclavicular brachial plexus block. Method A total number of 60 patients (ASA class 1 and II) were selected randomly into two groups, thirty in each group. Group-A (control group) received fentanyl (100ìg) 2ml and bupivacaine (0.25%) 38ml, total of 40ml.Group-B (study group) received clonidine (150ìg) 2ml and bupivacaine (0.25%) 38ml, total of 40ml.The parameters including pulse rate, non-invasive systolic and diastolic blood pressure, respiratory rate, SpO2, onset and duration of motor and sensory block, post operative pain score in VAS, duration of analgesia, first analgesic demand, side effects were assessed and recorded. Result Onset and duration of sensory block were significantly higher in group-B than in group-A (P<0.001) and motor block were quite prolonged in group-B than group-A (p<0.001), prevalence of sedation in group-B slightly higher than group-A. But intensity of pain measured by VAS in group-A expressed highest at 8 hours of postoperative period and group-B shows highest VAS at 12 hours. Duration of effective analgesia (time from supraclavicular block to first analgesic demand) in study group-B had significantly longer mean duration than that produced by control group-A (14.4 ± 1.3 vs 10.9 ± 1.5 hours; P<0.001). Conclusion Clonidine and bupivacaine combination is a better alternative to fentanyl and bupivacaine in respect of quality of anaesthesia and duration of analgesia.
