Background: Buprenorphine is being used as an adjuvant to local anaesthetic for spinal anaesthesia since long. Dexmedetomidine is a new drug which has got alpha 2 agonistic property, and is being tried for spinal anesthesia along with bupivacaine in recent times. Settings and Design: This study was conducted in a prospective, randomized, controlled and double-blind manner. The study included ninety American Society of Anaesthesiologists class I and II patients undergoing tibial interlocking nailing surgeries under spinal anaesthesia.Methods: The patients were randomly divided into three groups (n=30 each) by closed envelope technique. Patients in group 1 received 15 mg of 0.5% hyperbaric bupivacaine, group 2 received 15 mg of 0.5% hyperbaric bupivacaine with 30μg of buprenorphine, and group 3 received 15 mg of 0.5% hyperbaric bupivacaine with 5μg dexmedetomidine for spinal anesthesia. The duration of motor and sensory blockade and any adverse events were recorded. Data were analysed using Chi-square test or Fisher’s exact test for categorical data and analysis of variance for continuous data. A value of P<0.05 was considered as statistically significant.Results: In our study the subjects in group 3 (dexmedetomidine) group had significantly longer period of motor blockade (240±20min) and sensory blockade (180±22.2min) compared to other groups, which is statistically significant (P=0.0001 and P= 0.006 respectively). The time to first request of analgesic in the post-operative period was also longer (240±30.2min) in dexmedetomidine group when compared with other groups (P=0.0001). There were no untoward complications (hypotension, sedation) in any groups.Conclusions: We concluded that dexmedetomidine (5μg) with bupivacaine for spinal anesthesia gives significantly longer duration of sensory and motor blockade, than buprenorphine (30μg) with bupivacaine for spinal anaesthesia.

Background: Alpha-2 adrenergic agonists used as adjuvant to spinal anaesthesia produce substantial sensory and motor blockade of bupivacaine. This study was planned to compare the sensory and motor blockade characteristics of intrathecal combinations of adjuvants dexmedetomidine and clonidine with hyperbaric bupivacaine in the cases who underwent lower limb surgery under spinal anaesthesia.Methods: This was prospective, randomized, double blind study. 90 patients of age group between 18-60 years, ASA grade I and II were allotted into 3 equal groups. Group B received 15 mg bupivacaine plain, group BD and BC received dexmedetomidine (5mcg) and clonidine (50mcg) as adjuvants to bupivacaine respectively.Results: The duration of 2 dermatome regression time, sensory blockade and motor blockade were longest in dexmedetomidine group (129.37±4.87; 386±58.43; 353±48.87) in compared to clonidine (109.77±5.95; 296.53±57.19; 269.7±51.2) and bupivacaine group (81.03±6.83; 211.1± 30.47;181.03±20.8). Both drugs do not affect the peak level of sensory blockade, sensory block onset and motor block onset time. Dexmedetomidine and clonidine do not cause sedation in intraoperative and postoperative period.Conclusions: We conclude that addition of dexmedetomidine and clonidine in spinal anesthesia with hyperbaric bupivacaine increase the duration of ‘2 dermatome regression’ time, sensory and motor blockade and both are more with dexmedetomidine than with clonidine.

ABSTRACT Introduction This single-center, prospective, randomized, double-blind study compares the effect of intrathecal fentanylbupivacaine and tramadol-bupivacaine on the onset and duration of sensory and motor blockade, as well as postoperative analgesia in lower abdominal surgeries. Materials and methods Patients of either sex, aged 18 to 60 years, American Society of Anesthesiologists (ASA) grade I/II undergoing lower abdominal surgeries like appendicectomy, inguinal hernia repair surgery, and hydrocele surgery were administered either 2.5 mL of 0.5% bupivacaine + 0.5 mL (25 μg) of fentanyl citrate (group F) or 2.5 mL of 0.5% bupivacaine + 0.5 mL (25 mg) of tramadol (group T) intrathecally. Monitoring of the vital parameters, onset and duration of sensory and motor block, duration of postoperative analgesia, visual analog scale (VAS) score, sedation score, and any adverse drug reactions was done at predetermined intervals. Results Sixty patients were randomized to the group F (n = 30) and group T (n = 30). The duration of sensory blockade was significantly prolonged in group F (314.66 ± 49.25 minutes) as compared to group T (261.66 ± 27.92 minutes). Similarly, duration of motor blockade was longer in group F (263.66 ± 40.97 minutes) compared to group T (214.66 ± 26.61 minutes). The total duration of analgesia was significantly prolonged (p < 0.001) in group F (412 ± 97.888 minutes) compared to group T (301 ± 38.75 minutes). Hemodynamic parameters, such as pulse, systolic blood pressure, diastolic blood pressure and oxygen saturation were comparable in both the groups. Visual analog scores were significantly lower in the group F patients as compared to the group T patients. The group F patients had got significantly higher sedation scores as compared to Group T patients. Discussion Fentanyl 25 μg, when added to 2.5 mL of 0.5% hyperbaric bupivacaine, confers prolonged duration of sensory and motor blockade than 25 mg tramadol added to 2.5 mL of 0.5% hyperbaric bupivacaine. The bupivacaine-fentanyl combination prolonged duration of sensory and motor blockade, improved analgesia, as manifested by lower pain scores, and prolonged duration of postoperative analgesia.

Background: Bupivacaine being the drug of choice for spinal anaesthesia is associated with serious cardiac toxicity. Levobupivacaine and ropivacaine, both being the two S enantiomers of bupivacaine can be a safer alternatives with better cardiovascular safety. Hence, the clinical efficacy of both were assessed and compared in patients undergoing spinal anesthesia.Methods: A prospective randomized controlled double blind study was done in 68 adult posted for elective lower abdominal and lower limb surgeries under spinal anesthesia. They were randomized into 2 groups. About 3ml isobaric levobupivacaine 0.5% (15mg) was given in group A and 3ml isobaric ropivacaine 0.5% (15mg) was given in group B. Onset, duration of sensory and motor blocks, time for maximum sensory and motor block, time for 2 segment sensory regression and haemodynamic parameters were recorded and analyzed.Results: All patients achieved a sensory block of T10 dermatome. Onset of sensory blockade at T10 was similar in both groups, group A (5.71±1.31min) and group B (5.94±1.72min). Time from injection to two dermatomal regression was 129.68±15.54min in group A and 111.38±22.35min in group B. Onset of Bromage score of 1 in group A was 4.68±1.27min and in group B was 6.44±1.64min. The mean duration of motor and complete motor block was prolonged in group A patients (197.74±18.51min, 168.82±17.90 min) as compared to group B (131.88±20.41min, 106.71±10.85min).Conclusions: Isobaric levobupivacaine was found to be a better and safer substitute for spinal anesthesia in patients undergoing prolonged lower abdominal and lower limb surgeries.

Introduction:- Ketamine and Fentanyl used intrathecally as adjuvant to 0.5% hyperbaric bupivacaine for patients undergoing TAH to shorten the onset of sensory and motor blockade and prolonging the duration of block. Aims and Objective:-We evaluated onset and duration of sensory and motor blockade and timing of regression of sensory blockade to T 12 and motor blockade to Bromage scale 3. Material and Methods:-This analytical Comparative Study was conducted in Department of Anaesthesiology, Era’s Lucknow Medical College and Hospital, Era University, Lucknow over a period of eighteen months from 2016 -2018 following approval from institutional ethical committee and written informed patient consent. The sample size of 162 female patient aged 40 to 60 years, belonging to ASA physical status 1 and 2 undergoing TAH were randomly allocated to three groups in double blind manner. Group I Received Inj. Bupivacaine (0.5% Heavy) 3.0ml + Inj. Ketamine (25 mg), Group II Received Inj. Bupivacaine (0.5% Heavy) 3.0 ml + Inj. Fentanyl (25 µgm), Group III (Control Group): Received Inj. Bupivacaine (0.5% Heavy) 3.0 ml + Normal saline 0.5 ml. Onset and Duration of Sensory and Motor Blockade and time taken for regression of sensory level to T12 and motor level to Bromage scale 3 noted. Results:- The present study showed that both Ketamine as well as Fentanyl shortened the onset time and prolonged the block duration. However, with respect to onset time, ketamine has shorter onset of blockade than fentanyl. Conclusion:- Both the modalities independently assured quicker onset and prolonged duration of block, thus suggesting that adjuvant use of either of two could be beneficial.

Background The influence of spread of spinal anesthesia on the duration of spinal blockade has been suggested but never investigated specifically. Because elimination of local anesthetic from subarachnoid space is probably dependent of the surface available for its diffusion and vascular absorption, the current study was designed to evaluate the hypothesis that with a same dose of hyperbaric bupivacaine, a higher anesthetic level would result in a shorter duration of spinal blockade than a lower level. Methods Three milliliters (15 mg) of hyperbaric bupivacaine, 0.5%, was injected intrathecally in 40 patients classified as American Society of Anesthesiologists physical status I or H scheduled for lower limb surgery during spinal anesthesia. To obtain significantly different anesthetic levels, the patients were positioned randomly either horizontally or with the torso elevated 30. Regression of sensory level and motor blockade, the appearance of pain at the operative site, and hemodynamic changes were evaluated. Results The maximum cephalad spread of sensory blockade (expressed as the median with ranges in parentheses) was significantly higher in the horizontal group than in the group with 30-degree elevation of the torso, i.e., T3.5 (T1-T9) versus T10 (T6-L1), with respectively significantly faster regression times (mean ¿ SD) by two segments (216 ¿ 46 mm vs. 253 ¿ 64 mm) and to segment L4 (269 ¿ 53 mm i s. 337 ¿ 58 mm), as well as shorter time to complete motor blockade recovery (173 ¿ 34 mm i s. 233 ¿ 58 mm) and faster appearance of pain at the operative site (221 ¿ 68 mm vs. 271 ¿ 56 mm). Conclusion The results indicate that with the same dose of hyperbaric bupivacaine, the duration of spinal blockade is longer in patients with restricted spread.

Introduction.The aim of the study was to compare the sensory, motor, and neuroophthalmological effects of isobaric levobupivacaine and bupivacaine when intrathecally administered.Materials and Methods.A prospective, double-blind, randomized study with 60 ASA grade I-II patients aged 18–65 years awaiting knee arthroscopy under spinal anesthesia. Patients received 12.5 mg of isobaric bupivacaine or levobupivacaine. Several features were recorded.Results.No significant intergroup differences were observed for ASA classification, time to micturate, demographic data, surgery duration, and patient/surgeon satisfaction. Similar hemodynamic parameters and sensory/motor blockade duration were found for both groups. There were no neuroophthalmological effects in either group. Sensory (P=0.018) and motor blockade onset (P=0.003) was faster in the bupivacaine group. T6 (T2–T12) and T3 (T2–T12) were the highest sensory block levels for the levobupivacaine and bupivacaine groups, respectively (P=0.008). It took less time to regain maximum motor blockade in the bupivacaine group (P=0.014), and the levobupivacaine group required use of analgesia earlier (P=0.025).Conclusions.Isobaric bupivacaine and levobupivacaine are analogous and well-tolerated anesthetics for knee arthroscopy. However, for bupivacaine, sensory and motor blockade onset was faster, and greater sensory blockade with a longer postoperative painless period was achieved.

Objective: The purpose of the study is to compare and assess the sensoryand motor block along with the associated hemodynamic changes that occur in the patientpopulation operated for a lower segment cesarean section (LSCS), when they are given 0.5%hyperbaric bupivacaine versus 0.5% isobaric bupivacaine as used for spinal anesthesia.Study Design: Prospective double blind randomized trial. Period: 6 months duration fromApril 2014 to September 2014. Setting: A tertiary care hospital in the city of Karachi, Pakistan.Method: The study population consisted of 60 patients belonging to the ASA 1 and ASA 2category, who underwent a lower segment cesarean section, and comparative analysis ofthe efficacy and associated hemodynamic changes of hyperbaric with isobaric bupivacaine.The patient population was segmented into two groups both groups containing 30 patients,group A receiving hyperbaric bupivacaine 0.5% as 2.5ml ( 12.5mg dose ) and the secondgroup designated as, group B receiving isobaric bupivacaine 0.5% as 2.5ml ( 12.5mg dose)intrathecally. The resultant sensory and motor blockade was determined using pin prick andbromage scale respectively. Results: There was a significant difference found among the twogroups under study, when compared at 3min interval regarding the sensory blockade. The levelof T6 block was reached in 33.33% (n=10) patients belonging to group A and 56.66% (n= 17)patients in group B. It was observed that there was no significant change among the two groupsat 5min interval regarding sensory and motor blockade respectively. The immediate sensoryblockade with isobaric bupivacaine in group B produced greater decrease in the systolic andmean arterial blood pressure when contrasted with hyperbaric bupivacaine in group A at 5mininterval, but after time interval of 45min there was no statistically significant change observed.Conclusions: According to our study the effects of isobaric bupivacaine were more significantlypredictable; hence have a higher efficacy, when contrasted against hyperbaric bupivacainein lower section cesarean section spinal anesthesia. Quick sensory blockade with isobaricbupivacaine was associated with more decrease in blood pressures when contrasted with thehyperbaric bupivacaine, but this result is not statistically significant.

Background: Spinal anaesthesia remains one of the basic techniques in the arsenal of modern anaesthesiology despite the waxing and waning of its popularity over last 100 years since its introduction into clinical practice.It avoids biochemical and metabolic changes consequent to the stress of general anesthesia for surgery as well as provides near optimal conditions for surgery. In present study, we tried to study effectiveness of intrathecal 0.5% heavy bupivacaine alone with Dexmedetomidine as an adjuvant to intrathecal 0.5% heavy bupivacaine for lower limb and lower abdominal surgeries.Methods: The present study was conducted in the department of anaesthesiology from December 2011 to September 2013.This study was a prospective, randomised controlled, single blind, study conducted in 100 patients of ASA grade I and II undergoing elective surgeries under spinal anaesthesia. The patients were divided randomly into two groups, containing 50 patients in each group. Dosages of drugs selected are divided as Group B: Patients received 3 ml of 0.5% hyperbaric bupivacaine (15mg) and Group BD: Patients received 3 ml of 0.5% hyperbaric bupivacaine (15mg) plus 10 µg Dexmedetomidine. Spinal block characteristics, Mean arterial pressure, Mean pulse rate, sedation and side effects were studied during intra-operative and postoperative period.Results: It was found from present study that in Dexmedetomidine group time to reach T10 sensory blockade and complete motor blockade was earlier and a higher level of sensory blockade compared to control group achieved. Duration of sensory, motor blockade and duration of analgesia was significantly prolonged in the Dexmedetomidine group compared to the control group. Hemodynamic parameters were preserved both intra-operatively and postoperatively. However there were a small percentage of patients who developed hypotension and bradycardia which were easily managed without any untoward effect. Hence Dexmedetomidine is a better neuraxial adjuvant for providing early onset of sensory and motor blockade, prolonged sensory blockade and post operative analgesia and adequate sedation.Conclusions: Intrathecal low dose Dexmedetomidine in a dose of 10µg along with 0.5% hyperbaric bupivacaine is an addition into anaesthesiologist's armamentarium for spinal anaesthesia in patients undergoing elective lower abdominal and lower limb surgeries.

Objective: Spinal anaesthesia (SA) is a well-established technique for infra-umbilical surgeries but is underutilized in children. One important reason is the limited duration of action. Clonidine is a useful adjuvant in this regard but has not been studied in a dose of 1.5 μg/kg.Design: a prospective randomized study Setting: A single centre study conducted at a Super speciality paediatric tertiary care centre.Participants: Sixty children (5-12yrs) scheduled for lower abdominal surgery with duration <90min were included.Interventions: The participants were randomized into two groups to receive 0.4mg/kg of 0.5% hyperbaric bupivacaine with clonidine 1.5μg/kg (Group-I, n=30) or 0.4mg/kg of 0.5% hyperbaric bupivacaine with saline(Group-II, n=30) in the subarachnoid block.Main outcome measures: The sensory and motor block duration, time to two-segment regression, time to first rescue analgesic, and the number of rescue doses required were recorded.Results: Mean duration of sensory blockade (147.5±7.28 vs 310.33±10.17min; P<0.001) and motor blockade (132.5±10.06 vs 283.33±11.77min; P < 0.001) and duration of analgesia (172±9.61 vs 364.50±28.75min; P < 0.001) were significantly prolonged in the clonidine group. In the control group, most patients needed three analgesic doses over 24hr while in the clonidine group, the majority needed two doses. Adverse effects were infrequent in both groups.Conclusions: Clonidine as an adjuvant to 0.5% hyperbaric bupivacaine significantly prolonged the duration of analgesia with improved quality of anaesthesia while maintaining safety. We recommend the routine use of clonidine 1.5 μg/kg dose as an adjuvant to 0.5% bupivacaine in paediatric SA.
