Abstract
Peripheral nerve blocks have long been established as a crucial part of the enhanced recovery pathways after surgery. Interscalene brachial plexus block (ISB) is mainly indicated for anaesthesia and analgesia during shoulder and proximal arm surgery. Ultrasound technology has remarkably improved the efficacy and success rates of the ISB while limiting its potential complications.

Abstract
The supraclavicular block (SCB) and the infraclavicular block (ICB) are introduced to meet upper extremity surgery, where the transducer or the insertion point is placed superiorly and inferiorly at the approximate midpoint of the clavicle, respectively. These two approaches are highly appealing since they clearly exhibited each cord and its associated anatomy. In addition, it directed the needle accurately with real-time imaging by ultrasound guidance. Therefore, it brought higher success rates and fewer complications. Numerous trials have recently been conducted to examine the SCB and ICB regarding the new approach, injection techniques, block dynamics, and complication of hemidiaphragmatic paresis. It was found that both approaches could improve block effectiveness and postoperative analgesia for upper extremity surgery, according to recent studies at the level of the clavicular brachial plexus block. However, there is still a lack of work comparing the clinical performance and effectiveness of both approaches with ultrasonography. This review aims to outline the current available data from clinical trials along with case reports about these two approaches and to describe the findings published in the literature during the previous 5 years. Based on these findings, we attempt to determine whether there exists a one-size-fits-all approach that has the potential to meet upper extremity surgery.

Abstract
BACKGROUND Dexmedetomidine (DEX) provides a unique conscious sedation without respiratory depression. We examined the usefulness of intravenous (IV) DEX sedation combined with brachial plexus block for long-duration upper extremity surgery without an anesthesiologist. METHODS We retrospectively reviewed 90 limbs of 86 patients and measured the actual operative time course in detail. The adverse events and the patient-reported outcomes regarding intraoperative pain and depth of sedation were evaluated. RESULTS The mean total time of the operation, tourniquet use, and the IV DEX sedation were 150 min, 132 min, and 117 min, respectively. The mean time between discontinuation of IV DEX sedation and completion of the operation was 51 min. The intraoperative adverse events involved bradycardia (21%), hypotension (18%), and oxygen desaturation (3%). The mean visual analog scale scores of pain during brachial plexus block, surgical site pain, tourniquet pain, and depth of the sedation were 23.4 mm, 0.14 mm, 4.2 mm, and 6.6 mm, respectively. Furthermore, 96% patients expressed a preference for receiving anesthesia as brachial plexus block with IV DEX sedation. CONCLUSIONS Long-duration upper extremity surgery, even longer than 2 h, was feasible under brachial plexus block combined with IV DEX sedation without an anesthesiologist. For patients with low blood pressure and/or low heart rate, it is recommended to adjust the continuous infusion of IV DEX to less than 0.4 µg/kg/h. To ensure that the patients are able to promptly leave the operating room fully awake, IV DEX infusion should be stopped at least 30 min before finishing the operation.

Low-Volume Targeted Interscalene Brachial Plexus Block in the Emergency Department as a Safer Alternative for Pain Control for Glenohumeral Reduction: A Case Series. J Emerg Med 2023; 65:e204-e208.

Abstract
BACKGROUND Acute glenohumeral dislocation is a common emergency department (ED) presentation, however, pain control to facilitate reduction in these patients can be challenging. Although both procedural sedation and peripheral nerve blocks can provide effective analgesia, both also carry risks. Specifically, the interscalene brachial plexus block carries risk of ipsilateral hemidiaphragmatic paralysis due to inadvertent phrenic nerve involvement. There are techniques, however, that the emergency clinician can utilize to reduce these risks and optimize the interscalene brachial plexus block for specific pathologies such as glenohumeral dislocation. CASE SERIES We report three cases of patients who presented to the ED with acute anterior glenohumeral dislocation. Two of the patients had a history of pulmonary disease. In all three cases, targeted low-volume interscalene nerve blocks were performed and combined with systemic analgesia to facilitate successful closed glenohumeral reduction and reduce the risk of diaphragm paralysis. All 3 patients were monitored after the procedure and discharged from the ED. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Contrary to anesthesiologists who often seek to obtain dense surgical blocks, the goal of the emergency clinician should be to tailor blocks for specific procedures, patients, and pathologies. The emergency clinician can optimize the interscalene brachial plexus block for glenohumeral dislocation by using a low volume (5-10 mL) of anesthetic targeted to specific nerve roots (C5 and C6) to provide effective analgesia and reduce the risk diaphragm involvement.

Abstract
Background: Ultrasound-guided brachial plexus blocks (BPB) are used as an anaesthetic method in hand and wrist surgeries. The radial, median and ulnar nerves can also be selectively blocked. The objective of this retrospective cohort study was to compare distal nerve blocks (DNB) and BPB in terms of block success, block-related characteristics, time to discharge and patient satisfaction. Methods: The data of patients who underwent elective hand and wrist surgery under regional anaesthetic procedures between 01.01.2022 and 01.09.2022 were analysed. Standard multimodal analgesia was performed in all groups, in addition to either ultrasound-guided BPB or DNB. Demographic characteristics, American Society of Anaesthesiology (ASA) classes, presence of additional diseases, block and volume applied, block-related data such as block performance time, onset time, initial analgesia times, perioperative additional anaesthetic or analgesic requirement, surgery times, types of surgery, discharge times and the presence of additional complaints were recorded. In addition, the anaesthesia quality score were determined using a 5-point Likert scale. Results: There was no difference between demographic data. Average surgical time was similar between the DNB and BPB groups (46.0 ± 8.92 vs. 59.95 ± 22.04 min, p < 0.05). Block onset time was significantly lower in the DNB group (26.4 ± 2.73 vs. 32.17 ± 2.94 min, p < 0.001). When patients discharged before and after 12 hours were compared, 11/22 of the patients in the DNB group and 4/23 of the patients in the BPB group were discharged in the first 12 hours (p < 0.05). Patient satisfaction scores were similar between groups (14.22 ± 0.86 vs. 13.65 ± 1.11, p > 0.05). Conclusions: In surgeries of the hand and wrist, the radial, median and ulnar nerves can be used individually or in combination as an alternative to proximal BPB. Level of Evidence: Level III (Therapeutic).

Abstract
BACKGROUND Local anesthesia has shown to be safe and cost-effective for elective hand surgery procedures performed outside of the operating room. The economic benefits of local anesthesia compared to regional anesthesia for hand surgeries performed in the operating room involving repair of tendons, nerves, arteries, or bones are unclear. This study aimed to compare costs pertinent to hand surgeries performed in the main operating room under local anesthesia (LA) or brachial plexus (BP) block. METHODS We performed a cross-sectional study on the first 70 randomized patients from a prospective controlled trial of anesthesia modalities for hand surgery. The primary objective was to determine the mean anesthesia-related cost, and the secondary objectives were to analyze block performance time, block onset time, duration of anesthesia, duration of surgery, and time in the recovery room. RESULTS The mean anesthesia-related cost of performing hand surgery under LA as a wrist and/or digital block was $236 ± 30, compared to $435 ± 43 for BP, a difference of $199 per case. The mean block performance time was shorter for LA (1.3 minutes) versus BP (7.0 minutes). The mean anesthesia-related time was longer in BP (30.7 ± 16 minutes) compared to LA (17.7 ± 6.7 minutes), and consequently the total anesthesia time was longer in BP. CONCLUSIONS We demonstrated that local anesthesia compared to brachial plexus block achieved substantial cost savings in complex hand surgeries by decreasing major expenses. In an era of cost-consciousness, the use of LA represents an important modality for health systems to optimize patient flow and increase cost-effectiveness.

Abstract
Although brachial plexus block (BPB)-induced vasodilation reduces the incidence of arteriovenous access (AC) thrombosis, BPB cannot completely prevent its development. Therefore, we retrospectively investigated the factors affecting BPB-induced vasodilation and their effects on AC thrombosis development. Ninety-five patients undergoing AC surgery under BPB were analyzed. Vessel diameters were measured before and 20 min after BPB. The surgery abandoned before the BPB placement was performed when the BPB-induced increases in vessel diameters met its indications. Complete occlusive access thrombosis (COAT) was defined as loss of pulse, thrill, or bruit. Fourteen patients (14.7%) developed COAT. The outflow vein was more dilated by BPB than the inflow artery (0.6 versus 0.1 mm in median, p < 0.001). The original surgery plan was changed for seven patients (7.4%). Diabetes mellitus (DM) and ischemic heart disease (IHD) decreased the extent of increases in the inflow artery by -0.183 mm (95% confidence interval [CI] [-0.301, -0.065], p = 0.003) and outflow vein diameters by -0.402 mm (95% CI [-0.781, -0.024], p = 0.038), respectively. However, DM, IHD, and changes in the vessel diameters had insignificant effects on the development of COAT. In conclusion, although DM and IHD attenuate the vasodilating effects of BPB, they do not contribute to the development of COAT.

Abstract
BACKGROUND In a costoclavicular (CC) approach of an ultrasound (US)-guided infraclavicular brachial plexus block (BPB), a septum between the lateral and the medial/posterior cords can result in an incomplete block. We hypothesized that double injections in each compartment between the septum would result in a higher success rate of BPB than a single injection in the center of the CC space. OBJECTIVES This study was conducted to confirm the superiority of block quality achieved by septum-based double injections (experimental group; group E) over single injection in the center of the CC space (control group; group C). STUDY DESIGN A randomized, controlled trialSETTING: Department of Anesthesiology and Pain Medicine, Korea University College of Medicine, Anam Hospital. METHODS Sixty-eight patients who underwent upper extremity surgery randomly received a single (SI group, n = 34) or a septum-based double injection (DI group, n = 34) using the CC approach. Ten milliliters of 2% lidocaine, 10 mL of 0.75% ropivacaine, and 5 mL of normal saline were used for BPB in each group (total 25 mL). Sensory-motor blockade of the ipsilateral median, radial, ulnar, and musculocutaneous nerves was assessed by a blinded observer at 5-minute intervals for 30 minutes immediately after local anesthesia administration. The assessed variables were the success rate, the rate of all 4 nerves blockade, and onset time. RESULTS Thirty minutes after the block, the success rate was significantly higher in the DI group than in the SI group (64.7% in the SI group vs 91.2% in the DI group, P = 0.009), and the rate of all 4 nerves blockade also significantly increased in the DI group compared to the SI group (44.1% in the SI group vs 91.2% in the DI group, P = 0). The onset time was significantly shortened in the DI group compared with the SI group (26.3 ± 5.6 min in the SI group vs 21.3 ± 6.2 min in the DI group, P = 0.010). LIMITATIONS We considered that the location of the septum was always between the lateral cord superficially and the medial/posterior cords below it. In some patients in whom the septum was not visible, a superficial lateral cord was injected first, and then deep medial and posterior cords were injected, assuming that the 2 compartments were divided by the septum. CONCLUSIONS Compared with the SI, the septum-based DI of CC approach increased the success rate and the rate of all 4 nerves blockade and shortened the onset time.

Abstract
BACKGROUND Orthopedic procedures concerning the upper extremity commonly use a brachial plexus nerve block to achieve postoperative analgesia. The addition of dexamethasone to peripheral nerve blocks has been shown to significantly prolong its effect. We hypothesize that 1 mg doses of dexamethasone will prolong brachial plexus nerve block with similar efficacy to 4 mg and better than ropivacaine alone. METHODS Seventy-nine patients who received a brachial plexus nerve block prior to undergoing upper extremity surgery were randomized to 1 of 4 treatment groups: group 1 received only 30 mL of 0.5% ropivacaine without dexamethasone (control); groups 2, 3, and 4 received 4, 2, and 1 mg of dexamethasone, respectively, added to 30 mL of 0.5% ropivacaine. RESULTS Comparison of block duration, specifically "first signs of the block wearing off" to the 0-mg group, referencing the 1-, 2-, and 4-mg groups (P = .02, .04, and .01, respectively) that received steroid adjuvant therapy demonstrated a significant increase in time until the block began to wear off. All study groups receiving steroids also demonstrated a significant increase in duration of the block prior to its effects being completely gone when compared with the control group (P < .01 for all groups). CONCLUSIONS Our findings demonstrate that adjuvant dexamethasone can prolong brachial plexus nerve blocks effectively at low doses compared with high doses, in addition to prolonging analgesia compared with local anesthetic alone.

Abstract
BACKGROUND Appropriate postoperative pain management in shoulder surgeries is the mainstay of rehabilitation therapy and subsequent improved functional outcomes. However, adequate pain control either with opioids or interscalene brachial plexus block is often challenged by their side effects. In this context, this study compared the suprascapular nerve block (SSNB) to the newly emerging erector spinae plane block at the second thoracic vertebral level (high thoracic-ESPB) as an alternative pain therapy. OBJECTIVES This study aimed to compare the efficacy of high thoracic-ESPB with SSNB as analgesic options for arthroscopic shoulder surgery. STUDY DESIGN Prospective randomized, double-blinded, controlled, clinical trial. SETTING This clinical trial was performed at Zagazig University. METHODS This prospective, randomized controlled clinical trial was registered at ClinicalTrials.gov (NCT04669639, December 15, 2020). Patient enrollment was initiated after the registration date (December 20, 2020), and the study was conducted from December 2020 to November 2021. Ninety-six adult patients who prepared for arthroscopic surgeries were assigned to the high thoracic-ESPB group, SSNB group, and control group; all with 32 patients each. RESULTS A significant difference was found between the control group and block groups concerning the Numeric Rating Scale (NRS-11) at recovery, 2, 4, 6, 8, and 12 hours postoperatively at rest and with shoulder movement. However, the NRS-11 was significantly higher in the SSNB group than in the high thoracic-ESPB group only with movement both at recovery and 2 hours postoperatively. Otherwise, no significant difference between the 2 block groups was found throughout different time points of the study. The doses of fentanyl given intraoperatively were significantly higher in the control group than in the high thoracic-ESPB and SSNB groups (mean ± standard deviation [SD], 326.6 ± 45.8, 224.7 ± 17.1, and 232.8 ± 17.8; P value < 0.001, respectively). A significant difference also was observed concerning postoperative morphine use, where the mean ± SD was 18.8 ± 2.9 in the control group vs 5.7 ± 1.02 and 6 ± 0.81 (P value < 0.001) in the high thoracic-ESPB and SSNB groups, respectively. LIMITATIONS A continuous local anesthetic (LA) infusion catheter can be used either in the high thoracic-ESPB or SSNB to provide extended periods of analgesia. However, our investigation was confined to a single LA injection. CONCLUSIONS SSNB is not inferior to high thoracic-ESPB in the context of phrenic nerve sparing pain control for arthroscopic surgeries. Moreover, SSNB is a more established technique with more predicted sensory distributions and a lower risk of LA toxicity.

Abstract
BACKGROUND Studies on the evaluation of the Perfusion Index (PI) and the Pleth Variability Index (PVI) and the success of PI and PVI block in patients undergoing brachial plexus are limited and quite inadequate. AIM In our study, we aimed to compare PI and PVI between the interscalen block and infraclavicular block and evaluate its use as an early marker in block success. PATIENTS AND METHODS Single-center prospective randomized controlled trials. Preoperative unit, operating room. Patients over 18 years of age who have had upper extremity surgery. Brachial plexus block (interscalene, infraclavicular). Demographic data, Hemodynamic parameters, Perfusion index and Pleth Variability Index. 40 patients, including ASA1-2, 20 patients over the age of 18, who were planned for upper extremity surgery, in the interscalen group, and 20 in the supraclavicular group, were included in the study. Demographic data of the patients were recorded by measuring PI and PVI values at baseline before the block and at the 1st, 5th, 10th, 15th, and 20th minutes after the block, both simultaneously. RESULTS 62.5% (n = 25) of the patients included in the study were female. The mean age of the patients was detected as 52.63 ± 16.472, the mean BMI as 26.57 ± 4.423, and the mean entry hemoglobin level as 13.71 ± 1.87 g/dL. The hemodynamic data of the groups were similar across the time periods. The increase in PI increased significantly after 1 minute in both groups. The PVI was similar between the groups at all measurement times. CONCLUSION In our study, we observed an increase in PI from the 1st minute compared to the non-blocked arm in successful block applications. We consider the early indicator of PI in the evaluation of block success. In our study, we did not observe a significant change in the arm that was blocked and the arm that was not treated with PVI.

Abstract
OBJECTIVE To determine the effect of single-shot interscalene brachial plexus (ISBP) block on intracranial pressure (ICP) by evaluating the extravascular volume effect of the medicine on the internal jugular vein (IJV). STUDY DESIGN Interventional study. PLACE AND DURATION OF STUDY Department of Anaesthesiology and Reanimation, Sivas Cumhuriyet University, Sivas, Turkey, from January to June 2022. METHODOLOGY Thirty-four patients were included in this prospective clinical study. All patients had single-shot ISBP block with 25 ml of local anaesthetic. Optic nerve sheath diameter (ONSD), maximum (Dmax) and minimum (Dmin) diameters of IJV and IJV collapsibility index (IJV-CI) were recorded before the block (basal), 20 minutes, and 60 minutes after the block. RESULTS Twenty-nine patients had higher ONSD values at 60th minute compared to their basal values. There were negative correlations between the changes of ONSD and IJVCI (r=0.616, p<0.001) and ONSD and Dmax (r=0.581, p<0.001) in time period between basal and 20th minute. There were negative correlations between the changes of ONSD and IJVCI (r=0.518, p=0.002), ONSD and Dmax (r=0.664, p<0.001) in time period between basal and 60th minute. CONCLUSION Single-shot ISBP block with 25 ml of local anaesthetic may be a factor that increases ICP. Repeated intraoperative ONSD measurements are recommended in patients operated with ISBP block.

Abstract
BACKGROUND Shoulder dislocations are a common presenting injury to the emergency department (ED), with anterior dislocations comprising the majority of these cases. Some patients may tolerate gentle manipulation and reduction, but many require analgesia of some type. Oral or parenteral pain medication is often used alone or in combination with procedural sedation if gentle manipulation fails to achieve reduction. Recently, this treatment algorithm has grown to include regional anesthesia as a mode of analgesia for reduction of shoulder dislocations in the form of brachial plexus blocks. It has been well described that the interscalene and supraclavicular approach to the brachial plexus can be used to assist in reduction of anterior shoulder dislocations; however, there has yet to be any published literature regarding the use of ultrasound-guided retroclavicular approach to the infraclavicular region (RAPTIR) brachial plexus blocks for shoulder reduction. CASE REPORT We describe three patients who presented to the ED with anterior shoulder dislocations. The RAPTIR block was performed, provided effective analgesia, and facilitated successful shoulder reduction in all three patients.Why Should an Emergency Physician Be Aware of This? The RAPTIR nerve block is a safe and effective option for analgesia in the patient with an anterior shoulder dislocation. It may have advantages over other brachial nerve blocks and avoids the risks and disadvantages of procedural sedation and opioids.

Abstract
PURPOSE Remifentanil is useful in balanced anesthesia; however, there is concern regarding opioid-induced hyperalgesia. The effect of remifentanil on rebound pain, characterized by hyperalgesia after peripheral nerve block has rarely been studied. This study evaluated whether intraoperative remifentanil infusion may increase postoperative analgesic requirement in patients receiving preoperative interscalene brachial plexus block (IBP). METHODS Sixty-eight patients undergoing arthroscopic shoulder surgery under general anesthesia were randomly allocated to remifentanil (R) or control (C) group. Preoperative IBP with 0.5% ropivacaine 15 mL was performed in all patients. Intraoperative remifentanil was administered only in the R group. Postoperative pain was controlled using intravenous patient-controlled analgesia (IV-PCA) and rescue analgesics. The primary outcome was the dosage of fentanyl-nefopam IV-PCA infused over 24 h postoperatively. The secondary outcomes included the numeric rating scale (NRS) score recorded at 4-h intervals over 24 h, amount of rescue analgesics and total postoperative analgesics used over 24 h, occurrence of intraoperative hypotension, postoperative nausea and vomiting (PONV) and delirium. RESULTS The dosage of fentanyl-nefopam IV-PCA was significantly less in C group than R group for postoperative 24 h. Fentanyl 101 [63-158] (median [interquartile range]) µg was used in the C group, while fentanyl 161 [103-285] µg was used in the R group (median difference 64 µg, 95% CI 10-121 µg, P = 0.02). Nefopam 8.1 [5.0-12.6] mg was used in the C group, while nefopam 12.9 [8.2-22.8] mg was used in the R group (median difference 5.1 mg, 95% CI 0.8-9.7 mg, P = 0.02). The total analgesic consumption: the sum of PCA consumption and administered rescue analgesic dose, converted to morphine milligram equivalents, was higher in the R group than C group (median difference 10.9 mg, 95% CI 3.0-19.0 mg, P = 0.01). The average NRS score, the incidence of PONV and delirium, were similar in both groups. The incidence of intraoperative hypotension was higher in R group than C group (47.1% vs. 20.6%, P = 0.005). CONCLUSIONS Remifentanil administration during arthroscopic shoulder surgery in patients undergoing preoperative IBP increased postoperative analgesic consumption.

Abstract
OBJECTIVES The aim of this study was to evaluate the feasibility of the wide-awake local anesthesia no-tourniquet (WALANT) technique in radial shortening osteotomy and to compare it with the infraclavicular brachial plexus block (IBPB). PATIENTS AND METHODS Between January 2020 and January 2021, a total of 26 patients (16 males, 10 females, mean age: 40±4.9 years; range, 29 to 45 years) with Kienbock's disease who underwent radial shortening osteotomy were retrospectively analyzed. The patients were divided into two groups according to the type of anesthesia as WALANT (Group 1, n=11) and IBPB (Group 2, n=15) anesthesia. Visual Analog Scale (VAS) during surgery, time from anesthesia to surgical incision, surgical time, overall patient satisfaction regarding the anesthesia was assessed. The Quick Disabilities of the Arm, Shoulder and Hand (Q-DASH) and handgrip strengths were compared at the final follow-up and short-term outcomes were analyzed. RESULTS Age (p=0.896), sex (p=1.000), and dominant side involvement (p=1.000) were similar between the groups. Waiting time to start surgery in both groups was similar (27 vs. 25 min; p=0.053). Intraoperative VAS-pain scores and the satisfaction from the anesthesia type of both groups were also similar (p=0.546 and p=0.500). CONCLUSION The WALANT may be another anesthesia technique for radial shortening osteotomy with favorable outcomes. This technique adequately allows the surgeon to perform osteotomy and obtain a stable reduction without undue risk of tourniquet pain and palsy.

Abstract
Background We aimed to determine the minimum effective volume (MEV) of 0.5% bupivacaine for infraclavicular brachial plexus block. Methods We assigned patients to volume groups consisting of five consecutive patients. Local anesthetic was sequentially reduced from a starting dose of 30 mL by 2 mL to form the volume groups. Five patients were included in each volume group, and at least 3 of 5 injections had to be successful to consider the volume of the anesthetic as sufficient. The study ended when the anesthetic volume of a group was determined to be unsuccessful (two or fewer successful blocks). Block was successful if the patient reported a sensorial block score of 7 or more on an 8-point scale and sensorial and motor block's total score of 14 on a 16-point scale. Results The MEV of 0.5% bupivacaine for infraclavicular brachial plexus block was 14 mL. A successful block was achieved in all patients (n = 45) in 9 volume groups, which received 30 mL down to 14 mL. Three blocks were unsuccessful in the 12-mL group. Time to onset of block and time to first postoperative anesthetic administration was 15 (10–15) min and more than 24 h in the 30-mL bupivacaine group, but 40 (30–45) min and 14 (10–24) h were determined for the 14-mL group, respectively. Conclusions The MEV of 0.5% bupivacaine for ultrasound-guided infraclavicular brachial plexus block was 14 mL. However, this low-dose block has a long onset time of 40 (30–45) min on average.

Abstract
AIMS Ultrasound guidance has led to marked improvement in the success rate and characteristics of peripheral nerve blocks. However, effects of varying the volume or concentration of a fixed local anaesthetic dose on nerve block remains unclear. The purpose of our study was to evaluate whether at a fixed dose of lidocaine, altering the volume and concentration will have any effect on the onset time of ultrasound-guided axillary brachial plexus block. MATERIAL AND METHODS Twenty patients were randomised to receive an ultrasound-guided axillary brachial plexus block with either lidocaine 2% with epinephrine (20 ml, Group 2%) or lidocaine 1% with epinephrine (40 ml, Group 1%). The primary endpoint was block onset time. Secondary outcomes included duration of the block, performance time, number of needle passes, incidence of paraesthesia and vascular puncture. RESULTS The median [IQR] onset time of surgical anaesthesia was shorter in Group 1% when compared to Group 2% (6.25 [5-7.5] min vs 8.75 [7.5-10] min; p=0.03). The mean (SD) overall duration of surgical anaesthesia was significantly shorter in Group 1% compared to Group 2% (150.9±17.2 min vs 165.1±5.9 min; p=0.02). Group 1% had a shorter performance time with fewer needle passes. The incidence of vascular puncture and paraesthesia was similar in the two groups. CONCLUSION Ultrasound-guided axillary brachial plexus blocks performed using a higher volume of lower concentration lidocaine was associated with shorter onset time and duration of surgical anaesthesia.

Abstract
BACKGROUND We review the efficacy and safety of dexmedetomidine and clonidine as perineural or systemic adjuvants for brachial plexus blocks (BPB). METHODS We included randomised controlled trials on upper limb surgery with BPBs in adults, comparing dexmedetomidine with clonidine or either drug with placebo. The primary outcome was duration of analgesia. Secondary outcomes included adverse and serious adverse events. The review was conducted using Cochrane standards, trial sequential analyses (TSA) and Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS We included 101 trials with 6248 patients. Overall, duration of analgesia was prolonged with both clonidine (176 min [TSA adj. 95% CI: 118, 205, p < .00001; 33 trials]) and dexmedetomidine (292 min [TSA adj. 95% CI: 245 329, p < .00001; 53 trials]), but was longer for dexmedetomidine than clonidine (205 min [TSA adj. 95% CI: 157, 254, p < .00001; 19 trials]). Compared with placebo, dexmedetomidine was associated with bradycardia (RR 4.2 [95% CI 2.2, 8.3]), and both clonidine (RR 4.5 [95% CI 1.1, 18.3]) and dexmedetomidine (RR 3.9 [95% CI 2.0, 7.5]) were associated with hypotension. Serious adverse events were mostly related to block technique. GRADE-rated quality of evidence was low or very low. CONCLUSION Alpha2-receptor agonists used as adjuvants for BPBs lead to a prolonged duration of analgesia, with dexmedetomidine as the most efficient. Alpha2-receptor agonists were associated with increased risk of cardiovascular adverse events. The quality of evidence was low to very low.

Abstract
Nowadays, interscalene block is the gold standard for intra- and post-operative analgesia for shoulder surgery. It consists of distributing a sufficient volume of local anesthetics, within the interscalenic space which contains the C5 to C7 nerve roots. Due to its proximity to the area where the anesthetic is injected, the phrenic nerve can be transiently blocked causing a kind of paralysis of an hemidiaphragm. First, the use of ultrasound has reduced the incidence of diaphragmatic hemiparesis especially when the injection is performed at the C7 level rather than the C5 or C6 level. Then, decreasing the doses of local anesthetics has reduced the diffusion to the non-targeted structures, such as the phrenic nerve, causing less diaphragmatic hemiparesis. Finally, Palhais and Lee et al discovered that injecting LA at distance from the nerves roots can be useful in reducing this side effect. Based on their work, we decided to inject the local anesthetic into the muscle fascia. Our experience with this injection into the muscle itself seems to confirm the results described in the literature with less diaphragmatic hemiparesis. Further studies are needed to support our hypothesis and will be the subject of future researches in our institution.

Abstract
BACKGROUND Perineural (PN) dexamethasone (DEX) administration can prolong the analgesic time of a brachial plexus block. However, its efficacy and safety are controversial due to its off-label use and different routes of administration. OBJECTIVES This meta-analysis aimed to assess the safety and efficacy of PN versus intravenous (IV) dexamethasone. STUDY DESIGN Systematic review and meta-analysis of randomized controlled trials (RCTs). SETTING Relevant studies were found through a comprehensive literature search of PubMed, Web of Science, Ovid, EMBASE, and the Cochrane Library (from the inception until January 2020). METHODS According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this meta-analysis was conducted to identify RCTs comparing PN and IV dexamethasone in brachial plexus block. A randomized effect model was used in the meta-analysis and the subgroup analysis was performed with adrenaline stratification. The quality of evidence and the strength of recommendations were graded by GradePro version 3.6.1. RESULTS Twelve RCTs with a total of 1,345 subjects were included. We found that PN dexamethasone could prolong the duration of analgesia (mean difference [MD]: 131.82 minutes, 95% confidence interval [CI] [38.96, 224.68], I2 = 82%, P = 0.005), motor block (MD: 218.85 minutes, 95% CI [113.65,324.05], I2 = 72%, P < 0.0001) and sensory block (MD: 209.57 minutes, 95% CI [72.64, 346.50], I2 = 87%, P = 0.003) in the main analysis with significant difference. In the absence of epinephrine, there were no significant differences between PN dexamethasone and IV dexamethasone. Except for adverse-effects, no significant differences were observed in secondary outcomes. PN dexamethasone had slightly higher adverse-effects; however, these could be altered if a sensitivity analysis was conducted. LIMITATIONS There was high heterogeneity among included studies. CONCLUSIONS PN dexamethasone can prolong the duration of analgesia, sensory block, and motor block, when compared with IV dexamethasone. In a subgroup analysis without epinephrine, the 2 routes of administration were equivalent to topical anesthesia. There were no differences in secondary outcomes, except for adverse effects, which could be altered if a sensitivity analysis was conducted. Therefore, despite the advantages of PN dexamethasone, caution is needed due to its off-label character. While the results of this study are promising, additional large and well-designed RCTs are needed to validate these initial findings and their implications.

Abstract
BACKGROUND Patients often have moderate to severe pain after rotator cuff surgery, despite receiving analgesics and nerve blocks. There are many suggested ways to improve pain after rotator cuff surgery, but the effects of adopting a pathway that includes formal patient education, a long-acting nerve block, and extensive multimodal analgesia are unclear. QUESTIONS/PURPOSES (1) Does adoption of a clinical pathway incorporating patient education, a long-acting nerve block, and preemptive multimodal analgesia reduce the worst pain during the first 48 hours after surgery compared with current standard institutional practices? (2) Does adoption of the pathway reduce opioid use? (3) Does adoption of the pathway reduce side effects and improve patient-oriented outcomes? METHODS From September 2018 to January 2020, 281 patients scheduled for arthroscopic ambulatory rotator cuff surgery were identified for this paired sequential prospective cohort study. Among patients in the control group, 177 were identified, 33% (58) were not eligible, for 11% (20) staff was not available, 56% (99) were approached, 16% (29) declined, 40% (70) enrolled, and 40% (70) were analyzed (2% [4] lost to follow-up for secondary outcomes after postoperative day 2). For patients in the pathway cohort, 104 were identified, 17% (18) were not eligible, for 11% (11) staff was not available, 72% (75) were approached, 5% (5) declined, 67% (70) enrolled, and 67% (70) were analyzed (3% [3] lost to follow-up for secondary outcomes after postoperative day 2). No patients were lost to follow-up for primary outcome; for secondary outcomes, four were lost in the control group and three in the pathway group after postoperative day 2 (p = 0.70). The initial 70 patients enrolled received routine care (control group), and in a subsequent cohort, 70 patients received care guided by a pathway (pathway group). Of the 205 eligible patients, 68% (140) were included in the analysis. This was not a study comparing two tightly defined protocols but rather a study to determine whether adoption of a pathway would alter patient outcomes. For this reason, we used a pragmatic (real-world) study design that did not specify how control patients would be treated, and it did not require that all pathway patients receive all components of the pathway. We developed the pathway in coordination with a group of surgeons and anesthesiologists who agreed to apply the pathway as much as was viewed practical for each individual patient. Patients in both groups received a brachial plexus nerve block with sedation. Major differences between the pathway and control groups were: detailed patient education regarding reasonable pain expectations with a goal of reducing opioid use (no formal educational presentation was given to the control), a long-acting nerve block using bupivacaine with dexamethasone (control patients often received shorter-acting local anesthetic without perineural dexamethasone), and preemptive multimodal analgesia including intraoperative ketamine, postoperative acetaminophen, NSAIDs, and gabapentin at bedtime, with opioids as needed (control patients received postoperative opioids but most did not get postoperative NSAIDS and no controls received gabapentin or separate prescriptions for acetaminophen). The primary outcome was the numerical rating scale (NRS) worst pain with movement 0 to 48 hours after block placement. The NRS pain score ranges from 0 (no pain) to 10 (worst pain possible). The minimum clinically important difference (MCID) [12] for NRS that was used for calculation of the study sample size was 1.3 [18], although some authors suggest 1 [13] or 2 [5] are appropriate; if we had used an MCID of 2, the sample size would have been smaller. Secondary outcomes included NRS pain scores at rest, daily opioid use (postoperative day 1, 2, 7, 14), block duration, patient-oriented pain questions (postoperative day 1, 2, 7, 14), and patient and physician adherence to pathway. RESULTS On postoperative day 1, pathway patients had lower worst pain with movement (3.3 ± 3.1) compared with control patients (5.6 ± 3.0, mean difference -2.7 [95% CI -3.7 to -1.7]; p < 0.001); lower scores were also seen for pain at rest (1.9 ± 2.3 versus 4.0 ± 2.9, mean difference -2.0 [95% CI -2.8 to -1.3]; p < 0.001). Cumulative postoperative opioid use (0-48 hours) was reduced (pathway oral morphine equivalent use was 23 ± 28 mg versus 44 ± 35 mg, mean difference 21 [95% CI 10 to 32]; p < 0.01). The greatest difference in opioid use was in the first 24 hours after surgery (pathway 7 ± 12 mg versus control 21 ± 21 mg, mean difference -14 [95% CI -19 to -10]; p < 0.01). On postoperative day 1, pathway patients had less interference with staying asleep compared with control patients (0.5 ± 1.6 versus 2.6 ± 3.3, mean difference -2.2 [95% CI -3.3 to -1.1]; p < 0.001); lower scores were also seen for interference with activities (0.9 ± 2.3 versus 1.9 ± 2.9, mean difference -1.1 [95% CI -2 to -0.1]; p = 0.03). Satisfaction with pain treatment on postoperative day 1 was higher among pathway patients compared with control patients (9.2 ± 1.7 versus 8.2 ± 2.5, mean difference 1.0 [95% CI 0.3 to 1.8]; p < 0.001). On postoperative day 2, pathway patients had lower nausea scores compared with control patients (0.3 ± 1.1 versus 1 ± 2.1, mean difference -0.7 [95% CI -1.2 to -0.1]; p = 0.02); lower scores were also seen for drowsiness on postoperative day 1 (1.7 ± 2.7 versus 2.6 ± 2.6, mean difference -0.9 [95% CI - 1.7 to -0.1]; p = 0.03). CONCLUSION Adoption of the pathway was associated with improvement in the primary outcome (pain with movement) that exceeded the MCID. Patients in the pathway group had improved patient-oriented outcomes and fewer side effects. This pathway uses multiple analgesic drugs, which may pose risks to elderly patients, in particular. Therefore, in evaluating whether to use this pathway, clinicians should weigh the effect sizes against the potential risks that may emerge with large scale use, consider the difficulties involved in adapting a pathway to local practice so that pathway will persist, and recognize that this study only enrolled patients among surgeons and the anesthesiologists that advocated for the pathway; results may have been different with less enthusiastic clinicians. This pathway, based on a long-lasting nerve block, multimodal analgesia, and patient education can be considered for adoption. LEVEL OF EVIDENCE Level II, therapeutic study.

Abstract
Rotator cuff repair is known to cause significant pain, and therefore opioids are often prescribed postoperatively. The United States is currently experiencing an opioid epidemic, and prescription opioids are considered a gateway drug to opioid abuse and addiction. Orthopedic surgeons are looking for alternative means to control pain. The purpose of this study was to evaluate the efficacy of an opioid-free postoperative pain protocol in patients following an arthroscopic rotator cuff repair. A prospective study of 36 consecutive patients was performed. Patient demographics, prior narcotic consumption, past medical history, and visual analog scale (VAS) pain score were collected. All patients received an opioid-free postoperative pain protocol, including education, premedication, interscalene nerve blockade, and intraoperative injection, and were discharged with ketorolac, zolpidem, and acetaminophen. A sealed envelope containing an oxycodone prescription was also received at discharge. Patients were instructed only to fill the oxycodone prescription if they had uncontrolled pain. The primary outcomes were filling of the oxycodone prescription and use. Secondary outcomes were VAS pain scores and patient satisfaction scores. Sixty-seven percent of patients successfully completed opioid-free arthroscopic rotator cuff repair. Patients who did not use oxycodone had lower pain scores overall when comparing each postoperative day. By the first postoperative visit, patients who did not take oxycodone also demonstrated higher satisfaction with their pain management. This study demonstrates that with appropriate multimodal pain management, the majority of willing patients can undergo rotator cuff repair without use of opioids.

Abstract
PURPOSE Both intravenous dexamethasone and dexmedetomidine prolong the analgesic duration of interscalene blocks (ISB) after arthroscopic shoulder surgery. This study compared their relative effectiveness and the benefit of their use in combination. METHODS This single-centre, double-blinded, parallel three-group superiority trial randomized 198 adult patients undergoing ambulatory arthroscopic shoulder surgery. Patients received preoperative ISB with 30 mL 0.5% bupivacaine and 50 µg dexmedetomidine or 4 mg dexamethasone or both of these agents as intravenous adjuncts. The primary outcome was analgesic block duration. Secondary outcomes included the quality of recovery 15 score (range: 0-150) on day 1 and postoperative neurologic symptoms in the surgical arm. RESULTS Block durations (n = 195) with dexamethasone (median [range], 24.5 [2.0-339.5] hr) and both adjuncts (24.0 [1.5-157.0] hr) were prolonged compared with dexmedetomidine (16.0 [1.5-154.0] hr). When analyzed by linear regression after an unplanned log transformation because of right-skewed data, the corresponding prolongations of block duration were 59% (95% confidence interval [CI], 28 to 97) and 46% (95% CI, 18 to 80), respectively (both P < 0.001). The combined adjuncts were not superior to dexamethasone alone (-8%; 95% CI, -26 to 14; P = 0.42). Median [IQR] quality of recovery 15 scores (n = 197) were significantly different only between dexamethasone (126 [79-149]) and dexmedetomidine (118.5 [41-150], P = 0.004), but by an amount less than the 8-point minimum clinically important difference. CONCLUSION Dexamethasone is superior to dexmedetomidine as an intravenous adjunct for prolongation of bupivacaine-based ISB analgesic duration. There was no additional benefit to using both adjuncts in combination. TRIAL REGISTRATION www.clinicaltrials.gov (NCT03270033); registered 1 September 2017.
