The purpose of this study was to investigate if low doses of levobupivacaine (0.1%) produce complete sensory blockade in preoperative axillary brachial plexus block and to compare the effect of different doses of levobupivacaine on sensory and motor blockade. A total of 110 patients scheduled for elective forearm or hand surgery were randomly allocated to receive 36 ml or 72 ml of levobupivacaine 0.1% or 36 ml of levobupivacaine 0.25%. In each group, volumes were equally distributed in the four nerve territories. In all patients, the sensory and motor block was assessed at five, 10, 20 and 30 minutes after the placement of axillary block. Complete sensory block was obtained in 94.4% of patients receiving 36 ml of levobupivacaine 0.1%, 92.1% of those receiving 72 ml of levobupivacaine 0.1%, and 97.1% of those receiving 36 ml of levobupivacaine 0.25%. There was no significant difference either in the onset of the sensory and motor block or duration of the sensory and motor block. This study demonstrates that 36 ml of levobupivacaine 0.1% (36 mg) is as effective as higher doses and volumes in axillary brachial plexus blockade.

Background: As compared to general anaesthesia, brachial plexus block for upper limb surgery gives fewer side effects and better postoperative analgesia. The objective of this study was to evaluate the effects of 0.5% levobupivacaine and compare it with 0.75% ropivacaine.Methods: For this prospective randomized, controlled study, 60 patients of both sexes of ASA grade 1 and 2 were enrolled and divided into two groups and supraclavicular brachial plexus block was performed by lateral approach using 30 ml of 0.5% levobupivacaine and 0.75% ropivacaine. The onset of sensory and motor block, duration of sensory and motor block and analgesia and possible adverse events were recorded.Results: No statistically significant difference was observed in the onset of sensory block in both groups. Onset of motor block was significantly faster in levobupivacaine group (P<0.05). Duration of sensory block, motor block and analgesia was significantly longer in levobupivacaine group (P<0.05).Conclusions: 0.5% levobupivacaine is better alternative to 0.75% ropivacaine in brachial plexus block in term of early onset of sensory block and long duration of analgesia.

Objectives : To make a comparative evaluation of efficacy of brachial plexus blockade between supraclavicular subclavian perivascular technique and axillary transarterial technique with a tourniquet and also to compare the latency & potency of the block, to ascertain the risks of complications between the techniques and to compare the haemodynamic stability of the patient.Methods : For this purpose a total of 100 undergoing surgery for distal to the midarm. They were randomly selected by odd and even numbering method. These patients were divided into two groups (Group A: subclavian perivascular supraclavicular technique bearing all the odds numbers and Group B: transarterial axillary technique with a tourniquet bearing all the even numbers; fifty patients in each group.Results : The only exception is the mean on set time of sensory block was 11.0±2.6 minutes and 14.3±2.1 minutes in Group A and Group B respectively. The mean on set time of motor block were 18.3±3.9 minutes in Group A and 21.4±3.2 minutes in Group B. So the mean on set time of sensory block and motor block were statistically significant (p<0.05). Most of the patients found complete sensory block and complete motor block between two groups and no significant (p>0.05) difference was found in the present study. Adequate efficacy of block were predominate in both groups and no significant (p>0.05) difference was found. The level of satisfaction of surgeon and it was found that 92.0% in Group A and 94.0% in Group B were satisfied. Patient’s co-operation was found 92.0% and 94.0% in Group A and Group B respectively. No significant (p>0.05) difference were found in terms of surgeon satisfaction and patients cooperation between two groups.Conclusion : It can be concluded that the supraclavicular subclavian perivascular technique and axillary transarterial technique with a tourniquet both are equally effective and safe method for providing brachial plexus block distal to midarm (Lower half of the arm, elbow, forearm and hand).Chatt Maa Shi Hosp Med Coll J; Vol.14 (2); Jul 2015; Page 21-26

Abstract Background Brachial plexus block has substituted general anesthesia in the majority of patients planned for upper limb surgeries as it avoids the undesired effects of the medications used in general anesthesia as well as the stress response associated with airway manipulation. Opioid agonist–antagonists such as nalbuphine are used as adjuvant to improve the anesthetic properties of bupivacaine. Verapamil has an additive effect in brachial plexus blockade in the form of decreasing the consumption of analgesics in the postoperative period with reducing onset time and extending the duration of motor and sensory blockade. The aim of this study is to investigate the adjuvant effect of verapamil versus nalbuphine to 0.5% bupivacaine in brachial plexus block as regards onset, duration of sensory and motor blockade and postoperative analgesic augmentation. The study is randomized, prospective, double-blinded, comparative study where 90 patients subjected to arm, forearm and hand surgeries were randomized into three groups, group A received 30 ml of plain bupivacaine 0.5% plus 2 ml of normal saline, group B received 30 ml of bupivacaine 0.5% plus 2 ml verapamil equivalent to 5 mg, group C received 30 ml of bupivacaine 0.5% plus 10 mg of nalbuphine diluted in 2 ml of normal saline. Results Results of this study showed that group C and group B sensory block time onset was 7.25 ± 1.5 vs. 10.92 ± 3.84 min, P < 0.001 and was shorter than that in group A (13.2 ± 2.66 min). In addition, the motor block onset was (11.10 ± 1.24 vs. 13.50 ± 3.77 min, P < 0.001) shorter than group A (17.16 ± 1.30 min). In group C and group B, sensory block duration was 396 ± 32.17 vs. 355.83 ± 18.48 min, P < 0.001, respectively and was longer than that in group A (321.13 ± 25.08 min). Also, there was prolonged motor block duration in group C and group B recording (338.92 ± 25.2 vs. 302.93 ± 15.24 min, P < 0.001) and was longer than that in group A (280.70 ± 32.35 min). Time of demand of rescue analgesia dose was significantly long in group C and group B (449.53 ± 52.45 vs. 418.13 ± 41.12 min, P < 0.001) and was longer than group A (361.31 ± 21.42 min). Both verapamil and nalbuphine have additive effect to bupivacaine improving the all anesthetic parameters of the block. Conclusion Both drugs produce favorable enhancement of time onset and effective prolongation of duration of sensory and motor blockade and extend the period of postoperative analgesia with superiority to nalbuphine over verapamil.

BACKGROUND To improve the time of regional anaesthesia many methods have been used. Epinephrine continues to be the most commonly used drug for this purpose. We wanted to compare the effects of alpha-adrenergic agonists clonidine and adrenaline as an adjuvant to ropivacaine in blocking brachial plexus by the supraclavicular approach in patients undergoing upper limb surgeries. METHODS It is a prospective randomised comparative study conducted for 18 months in 40 patients randomly divided into group RA and group RC, conducted on American Society of Anesthesiology (ASA) I and II patients undergoing upper limb surgeries under supraclavicular brachial plexus block. In group RA 30 mL of 0.5 % ropivacaine with 5 microgram / mL of epinephrine was given and in group RC 30 mL of 0.5 % ropivacaine with 1 microgram / Kg of clonidine was given. RESULTS On comparing effects of added alpha-adrenergic agonists clonidine and epinephrine to ropivacaine for supraclavicular brachial plexus block, it was found that there was no significant difference in the onset of the sensory blockade and motor blockade in the two groups. Duration of sensory blockade was significantly more in the clonidine with ropivacaine group when compared with the epinephrine and ropivacaine. There was no significant difference in haemodynamic responses between the two groups. CONCLUSIONS Supraclavicular approach brachial plexus block is effective in terms of cost and performance, and the margin of safety along with good postoperative analgesia. Hence, it can be concluded that the addition of 1 µg / Kg of clonidine to 0.5 % ropivacaine in supraclavicular brachial plexus block provides a longer duration of analgesia as compared to 5 µg / mL of epinephrine added to 0.5 % ropivacaine.

ABSTRACTObjectives: Supraclavicular block of brachial plexus provides complete and reliable anesthesia for upper limb surgeries. Using adjuvant to localanesthetics, blocks can be prolonged to long durations. Peripheral nerve blocks thus help in avoiding the hazards of general anesthesia. We comparedthe sensory blockade, motor blockade, and duration of analgesia with the addition of fentanyl or dexmedetomidine to bupivacaine for supraclavicularbrachial plexus block.Methods: A total of 50 American Society of Anesthesiologist’s Physical Status I and II patients scheduled for elective upper limb surgeries undersupraclavicular brachial plexus block were divided into two equal groups in a randomized double-blinded fashion. Group BF received 30 mlbupivacaine with fentanyl 50 µg and Group BD received 30 ml bupivacaine with dexmedetomidine 50 µg. The characteristics for anesthesia andanalgesia were assessed in both groups.Results: Duration of sensory and motor block was 363.4±38.36 minutes and 357±36.77 minutes, respectively, in Group BF while it was452.96±77.12 minutes and 441.52±48.46 minutes in Group BD. There was a statistically significant difference in onset of sensory and motorblock between the two groups. The duration of analgesia (time to requirement of rescue analgesia) in Group BD was longer than in Group BF(471.44±65.88 minutes vs. 366.48±38.02 minutes) with (p<0.0001). There were minimum hemodynamic disturbances and side effects in any groupexcept for Grade 3 sedation score which was more in Group BD.Conclusion: Dexmedetomidine, when added to bupivacaine in supraclavicular brachial plexus block, enhanced the duration of sensory and motorblock and also the duration of analgesia, more than when fentanyl was added to bupivacaine.Keywords: Fentanyl, Dexmedetomidine, Bupivacaine, Supraclavicular brachial block.

It is important to develop a feasible animal model of regional anesthesia other than sciatic nerve blockade for pharmacokinetic investigations of new local anesthetics or analgesia in upper extremity surgery. Herein, we explored a nerve stimulator (NS)-guided brachial plexus block (BPB) in a rat model. The anatomy of the brachial plexus in rats was delineated in cadavers, and various BPBs were examined. The puncture point was located 0.5–1.0 cm below the lateral one-third of the clavicle. The efficacy and safety of the NS-guided BPB were evaluated using an injection of 2% lidocaine or 0.5% bupivacaine in 16 live animals; saline injection was used as a control. Both sides of the brachial plexus were located successfully using the NS-guided technique. Sensory blockade (nociception assessment) and motor blockade (grasping and straightening tests) appeared after application of the two classical local anesthetics, but not normal saline. The motor and sensory blockade induced by bupivacaine exhibited a longer duration than that induced by lidocaine ( p < 0.05). All rats recovered uneventfully from general anesthesia and BPB. No abnormal results were found in pathological studies or behavioral observations. Thus, a rat model of NS-guided BPB was established, and BPB induced an overall reversible sensory and motor blockade in the thoracic limbs. Evaluation of the efficacy and safety demonstrated that this rat BPB model was feasible, reproducible, and safe.

Background: Multiple studies have shown that perineural dexamethasone improves postoperative analgesia. However, some studies have shown minimal benefit, and have raised concerns regarding adverse physio-chemical effects of perineural dexamethasone. Furthermore, there is a paucity of studies wherein control (IV) dexamethasone was considered. Objective: The purpose of this meta-analysis was to evaluate the effectiveness of different concentrations of perineural dexamethasone injection on postoperative analgesia, as well as complications from its use for brachial plexus blocks. Methods: A systematic literature search was conducted using the Cochrane Central Registry of Controlled Trials, PubMed, and Scopus. Trials comparing control and local dexamethasonetreated groups, and those which reported duration of analgesia and/or pain scores/opioid consumptions were selected. Meta-analysis was performed using the Review Manager (RevMan) software 5.1. Results: Fourteen studies consisting of a total of 1,022 patients were included. Perineural dexamethasone significantly prolonged the duration of postoperative analgesia in patients receiving both low-dose (4 – 5 mg) [SMD 2.41 (95% CI: 1.47, 3.35 P = 0<0.00001) I2 = 82%], and higher-doses (8 – 10 mg) [SMD 4.46 (95% CI 3.54, 5.38 P < 0.00001) I2 = 94%]. However, the duration of motor block was also prolonged [SMD 2.52 (95% CI: 1.06, 3.98 P = 0.0007) I2 = 97%] and dexamethasone delayed latency of onset of sensory [SMD -0.49 (95% CI: -0.89, -0.09 P = 0.02) I2 = 76%] and motor [SMD -0.56 (95% CI: -1.13, 0.00 P = 0.05) I2 = 87%] blocks. Postoperative pain scores were improved at both 24 hours [SMD -1.46 (95% CI: -2.43, -0.50 P = 0.003) I2 = 95%] and 48 hours [SMD -1.20 (95% CI: -2.26, -0.13 P = 0.03) I2 = 95%] in dexamethasone-treated groups, whereas opioid consumption was reduced only at 48 hours [SMD -2.97 (95% CI: -4.17, -1.76 P < 0.00001) I2 = 88%]. Complications were comparable between control and dexamethasone-adjuvant groups, except for the excessively prolonged nerve block that was observed predominantly in the dexamethasone-adjuvant group. Limitations: The limitations include different definitions used for the measurements of certain parameters such as the duration of analgesia and duration of motor block, number of studies assessing certain parameters having high heterogeneity, and varying types of local anesthetics used in various studies. Conclusions: Perineural dexamethasone addition to local anesthetic solutions significantly improved postoperative pain in brachial plexus block without increasing complications. However, perineural adjuvant dexamethasone delayed the onset of sensory and motor block, and prolonged the duration of motor block. Smaller doses of dexamethasone (4 – 5 mg) were as effective as higher doses (8 – 10 mg).

Abstract Background In modern anesthesia practice, peripheral nerve block has a significant contributory role. Safety and accepted success rate have made this technique of anesthesia as very popular in ambulatory and inpatient anesthesia. Aim of the Work is to compare onset, degree of blockade, duration of blockade, duration of postoperative analgesia, and associated side effects after adding either magnesium sulfate or Ketamine to bupivacaine for performing supraclavicular Brachial Plexus Blocks for upper-limb surgeries. Patients and Methods After obtaining approval from the Research Ethical Committee of Ain Shams University, this study was conducted in the operating theatres of Ain Shams University Hospital. Randomized controlled double blinded study. Results Regarding the assessment of sensory block in the study, Onset times (mean ± SD) were (22.15 ± 3.20) mins, (17.35 ± 4.12) and (15.42 ± 3.23) mins in control, Magnesium and ketamin groups respectively. Adding ketamine or Magnesium significantly fastened the onset of sensory block with a highly significant difference (P &lt; 0.001) in comparison to control group. These results also demonstrated that Ketamin fastened the onset time more than Magnesium but there was no statistically significant difference between two groups. Conclusion Ultrasound guidance should be used as a routine technique for brachial plexus block and anaesthetists should gain experience in the application of ultrasound in all nerve blocks. Lower volumes and different types and concentrations of local anaesthetics should be tried in order to maintain effectiveness and decrease incidence of complications. Different doses of ketamin and magnesium sulfate should be tried to detect the ideal dose to be used as additive to local anaesthetics.

The axillary approach to brachial plexus blockade provides satisfactory anaesthesia for elbow, forearm, and hand surgery and also provides reliable cutaneous anaesthesia of the inner upper arm including the medial cutaneous nerve of arm and intercostobrachial nerve, areas often missed with other approaches. In addition, the axillary approach remains the safest of the four main options, as it does not risk blockade of the phrenic nerve, nor does it have the potential to cause pneumothorax, making it an ideal option for day case surgery. Historically, single-injection techniques have not provided reliable blockade in the musculocutaneous and radial nerve territories, but success rates have greatly improved with multiple-injection techniques whether using nerve stimulation or ultrasound guidance. Complete, reliable, rapid, and safe blockade of the arm is now achievable, and the paper summarizes the current position with particular reference to ultrasound guidance.

Brachial plexus block provide surgical anesthesia and analgesia of upper extremity. Any adjuvant to brachial plexus block have less systemic side effect as well as reduce the total dose local anaesthetics. The midazolam acts on GABA-A receptors in peripheral nerve. The sensory and motor block was significantly faster in our study who received midazolam. This could be local anesthetic properties of midazolam and synergistic action with local anaesthetics. Total 100 patients between ages 10-77 years of either sex of ASA I-III, underwent upper arm surgery were given supraclavicular brachial block with and without midazolam. The onset and duration of sensory block in Gr I (XB) and Gr II (XBM) were significantly different. The onset time for sensory block was significantly prolong and duration of block significantly less compared to Gr II (P<0.05). The onset time for motor block was significantly less and duration significantly higher in Gr II (XBM) as compared to Gr I (XB). Midazolam 50ugm/kg in brachial plexus block speed sensory and motor block with post operative analgesia.
