Abstract Background: Peripheral nerve block has gained increased popularity due to less postoperative pain, reduced need for postoperative analgesic drugs, reduction of PACU time, and improved patient satisfaction. The aim of the study was to compare the effect of ketamine and dexmedetomidine as additives to bupivacaine on onset and duration of the block, post-operative VAS, and analgesic consumption, after ultrasound-guided supraclavicular nerve block. Methods: 75 adult patients undergoing elective operations of the elbow, forearm, wrist, or hand were randomly allocated into three groups of 25 patients each. Group K (ketamine group) received 40 ml 0.25% bupivacaine contain 1 mg/kg ketamine, Group D (dexmedetomidine group) received 40 ml 0.25% bupivacaine contain 1ug/kg dexmedetomidine, group C (control group) received 40 ml 0.25% bupivacaine. The outcome measures included visual analog scale (VAS, 0 = no pain 10 cm = the most severe pain), time to first analgesic request, and total dose of diclofenac analgesia given postoperatively. Sedation score also recorded in all groups Results: Patients in D and K groups had reduced VAS scores than the C group, at all-time points after surgery during the first 24 hours, with more reduction in D than K group ( P < 0.05). The time of the first analgesic request in the D group was significantly more than in the K group and both were more than the C group (9.48±1.417 h, 7.08 ±1.255 h, and 5.00 ± 1.04 h respectively). Conclusions: The addition of ketamine or dexmedetomidine in the ultrasound-guided supraclavicular brachial plexus block could improve the postoperative pain and need for analgesia. Therefore, we can consider the low price more available ketamine as a comparable adjuvant in brachial plexus block to some extent as dexmedetomidine.

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: The present study was designed to evaluate the hypothesis that midazolam as an adjuvant to levobupivacaine would safely enhance the duration of analgesia without any adverse effects when compared with levobupivacaine alone, in ultrasound-guided supraclavicular brachial plexus block. Primary end points were the duration of sensory and motor block and secondary end points were sedation score and any other complications. Patients and Method: Eighty consenting patients of both sexes, aged 18-60 years of ASA physical status I-II were randomized into two groups of 40 patients each. Patients in Group LS received 19 ml of 0.5% levobupivacaine with 1 ml normal saline and patients in Group LM received 19 ml of 0.5% levobupivacaine with 1ml midazolam (50µg/kg) for supraclavicular brachial plexus block using ultrasound guidance. Onset time and duration of sensory and motor blockade and VAS scores were assessed as primary end points. Hemodynamic changes, sedation or any other drug or technique related adverse effects were taken as secondary effects. Results: Onset of sensory and motor blockade was lower in patients of Group LM. The mean duration of sensory analgesia was significantly prolonged in patients of Group LM (537.6 ± 101.01 vs. 319.80 ± 87.09 mins). The mean duration of motor blockade was also significantly enhanced in patients of Group LM (405.0 ± 61.62 mins) compared to Group LS (274.8 ± 46.30 mins). VAS scores were higher in Group LS than group LM. Sedation scores were similar in both the groups. Conclusion: Midazolam with 0.5% levobupivacaine has effectively enhanced the duration of sensory and motor block without significant sedation and any other side effect.

Abstract Background Poorly controlled acute pain after surgery is associated with a variety of unwanted postoperative consequences, including patient suffering, distress, myocardial ischemia, prolonged hospital stays and an increased likelihood of chronic pain. Systemic analgesics (opioids and non-opioids) have long been used for postoperative pain, then neuroaxial or peripheral nerve blocks were employed. Local anesthetics alone were used, then various adjuvants were added to achieve quick, dense and prolonged block. Objective The aim of this study was to study the effect of dexamethasone as an adjuvant to bupivacaine in supraclavicular brachial plexus block. The comparison included the onset and the duration of the sensory and motor blocks, the duration of analgesia of the block as well as their effects on the postoperative analgesic requirements. The effect of the drugs on hemodynamics and monitoring the occurrence of any complication were also done. Patients and Methods In our study, 60 patients were randomly divided into 2 equal groups. Control group received bupivacaine only (0.5%) and dexa group in which 8 mg of dexamethasone were added to bupivacaine. All patients received equal volumes of 20 milliliters. Results Our study showed that addition of 8 milligrams of dexamethasone to bupivacaine in ultrasound-guided supraclavicular nerve block shortened the onset times of motor blocks and significantly prolonged motor and sensory block durations. In addition, dexamethasone prolonged the duration of analgesia of the plexus block significantly, as proved by the time of request of analgesia. Moreover, in dexa group, postoperative analgesic requirements were greatly lesser than that of bupivacaine groups. Addition of dexamethasone also did not affect the hemodynamics to a significant level. This makes dexamethasone with bupivacaine more superior than the use of bupivacaine alone. Conclusion Addition of dexamethasone to bupivacaine in supraclavicular nerve block shortened the onset motor blocks. Addition of dexamethasone to bupivacaine significantly prolongs of both sensory and motor block durations.

Purpose: We evaluated the effect of adding Sufentanil to the mixture of Lidocaine and Bupivacaine used for supraclavicular brachial plexus block in reducing postoperative pain. Method: This double-blind clinical intervention trial was conducted in 2007. Patients scheduled to undergo upper limb orthopedic surgeries under supraclavicular brachial plexus block were recruited. Participants of one arm were given the mixture of Sufentanil, lidocaine, and bupivacaine (Group S) while those of the other arm were given the mixture of later two drugs (Group C). Postoperative pain assessment was done every hour postoperatively till the first administration of systemic analgesic. We used a subjective pain score and duration of lack of muscle movement as a parameter to judge outcomes. The mean and standard deviation were compared of both arms. Result: We included 50 patients in both arms. The mean duration of the motor blockade in group S and C were 342.8 (± 145.4) and 171.1 (±50.2) minutes respectively. The additive effect of Sufentanil in motor blockage was 171.7 (95% CI 128.5–214.9) (p = 0.1×10-6). The mean duration of analgesia in group S and C were 892 (±34.7) and 350 (±72.1) minutes respectively. The additive effect of Sufentanil in analgesia was 542 (95% CI 524–559) (p = 0.1×10-6). In group S, one patient developed cardiac pain following pneumothorax and two had temporary Horner syndrome. Conclusion: Analgesia in the postoperative period can be enhanced with the addition of Sufentanil (an opioid) to local anesthetics in supraclavicular brachial plexus block.
