“…To determine the sample size, we used sample size calculator for comparing two independent means [18]. It was calculated regarding the onset of analgesia using local anesthetics for supraclavicular nerve block, which was determined in previous studies [19]. Assuming a pooled standard deviation of 12 minutes and expected mean difference of 10 minutes between test and reference groups, the study would require a sample size of 23 patients for each group, with a power of 80%-and twosided level of significance of 5%, at a confidence interval (CI) of 95%.…”

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 on the 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 alltime 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:Coracoid approach is efficient and safe for brachial plexus block, and is guided by nerve stimulator or ultrasound in general. Many trials have proved that ultrasonic guidance was more efficacious than nerve stimulator guidance. We hypothesized that positioning posterior cord could enhance the anesthesia effect of coracoid approach brachial plexus block (CABPB) guided by nerve stimulator.Methods:Eighty patients were randomized into 2 groups to receive CABPB with positioning posterior cord guided by nerve stimulator (group A) or CABPB guided by ultrasound (group B). Success rate, procedure time, and onset time of sensory or motor block were recorded.Results:Success rate was similar in 2 groups (89.7% in group A vs 87.5% in group B, P > .05). Procedure time was longer in group A (8 minutes), as compared with group B (4 minutes; P < .05). The difference of onset time of sensory and motor block was not significant between the 2 groups. The onset time of sensory and motor block for musculocutaneous nerve was significantly shorter in group A, as compared with group B (P < .05).Conclusion:The 2 technologies are equivalent regarding success rate, safety, and onset time of sensory or motor block. Positioning posterior cord in CABPB guided by nerve stimulator is efficacious for upper extremity surgery.(URL: http://www.chictr.org.cn/listbycreater.aspx ID: ChiCTR-INR-16009091 DATE: 25/8/2016)

Regional anesthesia is becoming increasingly popular among anesthesiologists in the management of postoperative analgesia following pediatric surgery. The main objective of this review was to systematically evaluate the last 5 years of randomized controlled trials on the role of regional anesthesia techniques in alleviating postoperative pain associated with various pediatric surgical procedures. Forty studies on 2,408 pediatric patients were evaluated. The majority of the articles published from 2013 to 2017 reported that the use of regional anesthesia minimized postoperative pain and reduced opioid consumption. Only a few surgical procedures (cholecystectomy, inguinal hernia repair, and non-laparoscopic major abdominal surgery) reported no significant difference in the postoperative pain relief compared with the standard anesthetic management. The growing number of randomized controlled trials in the pediatric literature is very promising; however, additional confirmation is needed to reinforce the use of specific regional anesthesia techniques to provide optimal postoperative pain relief for a few surgical procedures (reconstructive ear surgery, chest wall deformity, hypospadias, umbilical hernia, cleft palate repair) in pediatric patients. More randomized controlled trials are needed to establish regional anesthesia as an essential component of postoperative analgesia management in children.

Faster onset time of supraclavicular brachial plexus block using local anesthetic diluted with dextrose

Abstract: We conclude that there was a decrease in onset time of analgesia when dextrose was used as a diluent instead of saline for ultrasound guided supraclavicular block.
