Abstract
BACKGROUND Interscalene block is the most commonly used nerve block for shoulder surgery, and superior trunk block has been investigated as a phrenic-sparing alternative. This randomized controlled trial compared ultrasound-guided interscalene block and superior trunk block as anesthesia for arthroscopic shoulder surgery. OBJECTIVES Our aims were to determine the superiority of anesthesia quality and compare the risk of hemidiaphragmatic paralysis between these 2 blocks. STUDY DESIGN A randomized, controlled trial. SETTING Department of Anesthesiology and Pain Medicine, Korea University Anam Hospital. METHODS Forty-eight patients undergoing elective arthroscopic shoulder surgery under an ultrasound guided brachial plexus block were randomized to receive either an interscalene block (ISB group, n = 24) or a superior trunk block (STB group, n = 24) for surgery. Ten milliliters of 2% lidocaine and 10 mL of 0.75% ropivacaine were used as local anesthesia in both brachial plexus block groups (total 20 mL). In the ISB group, the local anesthesia was injected between the C5-C6 root and at the upper part of C5 with equally divided doses. In the STB group, the local anesthesia was injected into the anterior and posterior parts of the superior trunk with equally divided doses. Sensory blockade of each trocar's insulting site (supraclavicular, axillary, and suprascapular nerve areas) and motor blockade of the axillary nerve (shoulder abduction) and the suprascapular nerve (shoulder external rotation) were assessed by a blinded observer at 5-minute intervals for 30 minutes after the block. Anesthesia quality was assessed using 3 grades (excellent/insufficient/failure). The blinded investigator also assessed the grade of hemidiaphragmatic paralysis (normal/partial/complete) by comparing pre- and postoperative chest radiographs. Primary outcome variables were anesthesia grade and rate of hemidiaphragmatic paralysis. Secondary outcome variables were performance time and anesthesia onset time. RESULTS The anesthetic grade was significantly different between the 2 groups (22/2/0 in the ISB group vs. 16/3/5 in the STB group, P = 0.046). Both groups displayed equivalent incidence of hemidiaphragmatic paralysis (12/6/6 in the ISB group vs. 7/14/3 in the STB group, P = 0.063). No intergroup differences were found in terms of performance time and anesthesia onset time. LIMITATIONS Our sensory and motor function test was not applied to the subscapular nerve, which serves internal rotation of the humeral head so may be difficult to evaluate in patients with rotator cuff tears. We assessed the diaphragmatic movement by chest radiographs instead of by ultrasound. CONCLUSIONS The superior trunk block provided lower quality of surgical anesthesia than the interscalene block and did not effectively decrease the risk of hemidiaphragmatic paralysis during arthroscopic shoulder surgery for rotator cuff syndrome.

The effect of wide-awake anesthesia, intravenous regional anesthesia, and infraclavicular brachial plexus block on cost and clinical scores of patients undergoing hand surgery. HAND SURGERY & REHABILITATION 2021; 40:382-388. [PMID: 33823293 DOI: 10.1016/j.hansur.2021.03.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Revised: 02/21/2021] [Accepted: 03/30/2021] [Indexed: 11/19/2022]
Abstract
The aim of our study was to compare the clinical results and costs of wide-awake local anesthesia no tourniquet (WALANT), intravenous regional anesthesia (IVRA), and infraclavicular brachial plexus block (IC-BPB). The patients were divided into WALANT, IVRA, IC-BPB groups, each with 50 patients. Demographic information, induction time, use of sedation, number of patients who were converted to general anesthesia, time in postanesthesia care unit (PACU), amount of bleeding during surgery, presence of tourniquet pain, hand motor function during surgery, time to onset of postanesthesia pain, discharge time, complications, and anesthesia costs were compared. Sedation was given to 12 IC-BPB patients, 9 IVRA patients and 5 WALANT patients. Of these patients, 6 undergoing IC-BPB, 5 undergoing IVRA and 4 undergoing WALANT were converted to general anesthesia (p = 0.80). PACU time and anesthesia costs were the least in the WALANT group, followed by the IVRA group (p < 0.001, p < 0.001). Intraoperative active voluntary movements were best preserved in the WALANT group; however, bleeding was highest in the WALANT group (p < 0.001, p < 0.001). Tourniquet pain was the higher in the IVRA groups, while postoperative pain in the surgical area developed the fastest in this same group (p = 0.029, p < 0.001). Time to discharge was similar in WALANT and IVRA groups, and the longest in the IC-BPB (p < 0.001) group. There was no difference among the groups in terms of patient satisfaction (p = 0.085, p = 0.242 for the first and second survey question). In the current study, WALANT appears to be a suitable alternative to IVRA and IC-BPB methods, with better preservation of active intraoperative movement, lower cost, and shorter time spent in PACU at the expense of higher bleeding.

Abstract
PURPOSE Intraoperative nerve dysfunction has been difficult to investigate because of its rarity and unpredictable occurrence. The diagnostic test attributes of nerve function monitors have not been clearly defined. This proof-of-concept study aimed to assess the feasibility of using brachial plexus blockade (BPB) in awake patients as an experimental model for nerve dysfunction to characterize the diagnostic test attributes of somatosensory evoked potentials (SSEPs). METHODS We obtained baseline SSEPs and neurologic function in patients and subsequently placed BPBs (experimental model) to generate progressive states of nerve dysfunction. We monitored SSEP changes (index test) and neurologic symptoms (reference standard) simultaneously during the onset of BPB to determine the temporal relationships and diagnostic test attributes of SSEPs. RESULTS Brachial plexus blockade produced differential motor and sensory dysfunction that allowed simultaneous clinical and neurophysiologic assessment. One hundred and fifty-seven pairs of multiple data points from 14 patients were included for final analysis. The onset of abnormal SSEP signals almost always preceded the onset of neurologic symptoms. The sensitivities and specificities of SSEP to detect the impairment of power (motor rating score ≤ 4/5), cold sensation, and two-point discrimination were 100% and 67%, 99% and 55%, and 100% and 46%, respectively. CONCLUSION This study found that BPB can produce sufficient differential nerve dysfunction to allow adequate evaluation of the diagnostic test attributes of SSEPs as a nerve monitor. The results of this study may stimulate further work on refining intraoperative nerve dysfunction models and diagnostic nerve function monitors.

Abstract
Peripheral Arterial Obstructive Disease (PAOD) may course with severe ischemic pain. In low-income health systems, patients may wait for vascular surgery. Continuous peripheral nerve block may be an effective alternative, with fewer side effects, in this scenario. A female patient with acute arterial obstruction of upper limb evolving with severe ischemic pain. She was submitted to a continuous infraclavicular brachial plexus block, which led to a satisfying pain control until the amputation surgery. The early postoperative period evolved with good pain management. This approach may be effective and safe as an analgesia option for ischemic pain.

Abstract
PURPOSE OF REVIEW This evidence-based systematic review will focus on the use of dexmedetomidine and its role as adjuvant anesthetics in regional blocks to help better guide physicians in their practice. This review will cover background and mechanism of dexmedetomidine as well as the use in various regional blocks. RECENT FINDINGS Local anesthetics are preferred for nerve blocks over opioids; however, both due come with its own side effects. Local anesthetics may be toxic as they disrupt cell membrane and proteins, but by using adjuvants such as dexmedetomidine, that can prolong sensory and motor blocks can reduce total amount of local anesthetics needed. Dexmedetomidine is an alpha-2-adrenergic agonist used as additive for regional nerve block. It has a relatively low side effect profile and have been researched in various regional blocks (intrathecal, paravertebral, axillary, infraclavicular brachial plexus, interscalene). Dexmedetomidine shows promising results as adjuvant anesthetics in most regional blocks. SUMMARY Many studies have been done and many show promising results for the use of dexmedetomidine in regional blocks. It may significantly increase in duration of sensory and motor blocks that correlates with lower pain scores and less need of morphine in various regional blocks.

Abstract
BACKGROUND The possibility of local infiltration analgesia (LIA) replacing interscalene blockade (ISB) as an integral component of a multimodal clinical pathway for total shoulder arthroplasty (TSA) needs to be further investigated. We thus further designed a randomized controlled study to compare LIA with ISB in the treatment of TSA. METHODS This blinded and randomised study was performed after approval of the institutional review board in the first affiliated hospital of Jinan University. The included patients were all aged over 18 years and underwent shoulder arthroplasty because of osteoarthritis of the shoulder. Subjects were randomized into 2 groups as follows: LIA or ISB. The primary outcome of this noninferiority study is opioid consumption within the first 24 hours following surgery. Secondary outcomes included pain scores, length of hospital stay, complication, and satisfaction score. P value < .05 was considered statistically significant. RESULTS For the present trial, we hypothesized that there would be no difference in pain score levels and opioid medication use throughout admission. TRIAL REGISTRATION This study protocol was registered in Research Registry (researchregistry5640).

Abstract
OBJECTIVES We compared the analgesic efficacy of a continuous suprascapular nerve block (C-SSNB) and a single-shot interscalene brachial plexus block (S-ISNB) for postoperative pain management in patients undergoing arthroscopic rotator cuff repair. METHODS A total of 118 patients undergoing arthroscopic rotator cuff repair were randomly allocated to the S-ISNB or C-SSNB groups. Postoperative pain was assessed using the visual analog scale (VAS) at 1, 2, 6, 12, and 24 h postoperatively. Supplemental analgesic use was recorded as total equianalgesic fentanyl consumption. RESULTS The C-SSNB group showed significantly higher VAS scores at 0-1 h and 1-2 h after the surgery than the S-ISNB group (4.9±2.2 versus 2.3±2.2; p<0.0001 and 4.8±2.1 versus 2.4±2.3; p<0.0001, respectively). The C-SSNB group showed significantly lower VAS scores at 6-12 h after the surgery than the S-ISNB group (4.1±1.8 versus. 5.0±2.5; p=0.031). The C-SSNB group required significantly higher doses of total equianalgesic fentanyl in the post-anesthesia care unit than the S-ISNB group (53.66±44.95 versus 5.93±18.25; p<0.0001). Total equianalgesic fentanyl in the ward and total equianalgesic fentanyl throughout the hospital period were similar between the groups (145.99±152.60 versus 206.13±178.79; p=0.052 and 199.72±165.50 versus 212.15±180.09; p=0.697, respectively). CONCLUSION C-SSNB was more effective than S-ISNB at 6-12 h after the surgery for postoperative analgesia after arthroscopic rotator cuff repair.

Abstract
Clavicle fractures are common, and there has been a recent increase in surgical fixation of displaced fractures. General anesthesia is traditionally preferred for these operations because regional anesthesia can be challenging. This is partly due to a complex nerve innervation in this region, which makes the correct choice of nerve block difficult. The objective of this study was to evaluate the efficacy of a combined interscalene brachial plexus block and superficial cervical plexus peripheral nerve block as anesthesia for clavicle surgical procedures. Ten midshaft clavicle fractures were surgically repaired using a combination of an ultrasound-guided interscalene brachial plexus block and a superficial cervical plexus block as the primary anesthetic. All patients underwent surgery successfully using regional anesthesia with light sedation, without the need for rescue opioids or rescue local anesthesia. No adverse events were recorded. This case series describes a successful peripheral nerve block combination that can be used for clavicle surgery.

Abstract
Background Brachial plexus block is popular choice for upper limb surgeries and offers good and relatively safe anesthesia. Among various approaches supraclavicular approach is the most consistent method for anaesthesia and postoperative pain management in surgery below the elbow joint. Many drugs are used as adjuvants in brachial plexus block for faster onset, denser block and for prolongation of postoperative analgesia. Dexmedetomidine also has been shown to prolong the sensory and motor duration when added as an adjuvant to local anaesthetic in nerve blocks. Objective To assess the effect of adding dexmedetomidine to ropivacaine in brachial block. Method Sixty patients, planned for upper limb surgeries under ultrasound guided brachial block were randomly allocated into two groups. Group RS (n=30) received 30 ml of 0.5% Ropivacaine + 1 ml Normal Saline and Group RD (n=30) received 30 ml of 0.5% Ropivacaine + 0.75 mcg/kg Dexmedetomidine diluted to 1 ml solution. The onset time to sensory and motor blockade were recorded. The duration of sensory and motor block and duration of analgesia were recorded. Result The mean time to onset of sensory block (12.60±2.67 min Vs 22.17±2.81 min) and motor block (14.20±3.22 min Vs 22.53±3.97) in Group RD was significantly faster in Group RD than Group RS. The mean duration of sensory block (838.70±164.11 min Vs 670.20±145.16 min), motor block (804.16±148.71 min Vs 594.93±53.89 min) and duration of analgesia (1193.80±223.11 min Vs 828.23±136.30 min) were significantly longer in Group RD compared to Group RS. The incidence of side effects in both groups were comparable. Conclusion From this study, it can be concluded that addition of Dexmedetomidine 0.75 mcg/ kg to 0.5% Ropivacaine results in early onset of sensory and motor blockade, prolongation of duration of sensory and motor blockade and duration of analgesia postoperatively without any significant side effects.

Abstract
Background and objectives Ultrasound-guided upper limb blocks may provide great benefits to patients with serious diseases. Patients with Steinert's disease have muscle weakness and risk of triggering myotony or malignant hyperthermia due to the use of anesthetic agents and surgical stress. The objective of this report was to demonstrate a viable alternative for clavicle fracture surgery with upper trunk and supraclavicular nerve block, thus reducing the spread of local anesthetic to the phrenic nerve in a patient with muscular dystrophy. Case report A 53-year-old male patient with Steinert's disease, associated with dyspnea, hoarseness and dysphagia, referred to the surgical theater for osteosynthesis of clavicle fracture. Upper limb (1 mL 0.75% ropivacaine) and supraclavicular nerve block (1 mL 0.75% ropivacaine in each branch) were combined with venous anesthesia with propofol under laryngeal mask (infusion pump target of 4 mcg.mL−1). Upon awakening, the patient had no pain or respiratory complaints. He was transferred to the ICU for immediate postoperative follow-up with discharge from this unit after 24 h without complications. Conclusions The superior trunk and cervical plexus block associated with venous anesthesia under laryngeal mask, without the use of opioids, proved to be adequate in the case of a patient with clavicle fracture and Steinert's disease. With the use of ultrasonography in regional anesthesia it is possible to perform increasingly selective blocks, thus allowing greater security for the anesthetic-surgical procedure and lower morbidity for the patient.

Abstract
OBJECTIVE To evaluate the effect of dexmedetomidine combined with ropivacaine on brachial plexus block in patients scheduled for elective shoulder arthroscopy. METHODS Ninety patients with American Society of Anesthesiologists (ASA) I or II, scheduled for elective shoulder arthroscopy, were randomly divided into three groups. In group R (n=30), the patients were given 10 mL of 0.375% ropivacaine in branchial plexus block (interscalene approach guided by ultrasound), in group D1 (n=30), the patients were given 10 mL of 0.375% ropivacaine (interscalene approach guided by ultrasound) + dexmedetomidine 0.2 μg/(kg×h) (intravenous pump infusion), and in group D2 (n=30), the patients were given 10 mL of 0.375% ropivacaine (interscalene approach guided by ultrasound) + dexedetomidine 0.7 μg/(kg×h) (intravenous pump infusion). To evaluate the effect of brachial plexus block before general anesthesia. Group D1 and group D2 were given dexmedetomidine intravenously for 1.0 μg/kg during 10 min, then the drug was pumped by 0.2 μg/(kg×h) and 0.7 μg/(kg×h) respectively until 30 min before the operation finished. Changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and before anesthesia (T0), 10 min (T1), 30 min (T2) after giving dexmedetomidine, discontinue medication (T3), after operation (T4), and extubation (T5) were investigated. Motor and sensory block onset times, block durations, and duration of analgesia were recorded. The scores of pain after operation and the adverse effects of shiver, hypopiesia, drowsiness, and blood loss were recorded during operation. RESULTS Compared with group R, the duration of analgesia and duration of sensory block in group D1 and group D2 were significant longer (P<0.01), there was no significant difference between groups D1 and D2 (P>0.05). Compared with group R, at each time point of T1-T5, the heart rate and systolic blood pressure in group D1 and group D2 were significantly decreased (P<0.01). Compared with D1 group, the incidence of hypotension and bradycardia in group D2 were significantly different (P<0.05). CONCLUSION Intravenous dexmedetomidine could prolong the duration of analgesia time and sensory block within the brachial plexus block, inhibiting the stress response during arthroscopic shoulder surgery. Compared with high-dose, low-dose can provide safer and better clinical effect and reduce the adverse effects of dexmedetomidine.

Abstract
BACKGROUND Interscalene brachial plexus block (ISB) is the gold standard for postoperative pain management in shoulder surgery. However, this technique has side effects and potentially serious complications. The aim of this study was to compare the combinations of ultrasound-guided suprascapular (SSB) associated with supraclavicular nerve block (SCB) and ultrasound-guided ISB for postoperative analgesia after shoulder instability surgery. METHODS Sixty ASA physical status I-II patients scheduled to undergo shoulder instability surgery were included. Two groups: (i) the SSB+SCB group (n=30) in which the patients received a combination of US-guided SSB (15mL of bupivacaine 0.25%) and US-guided SCB (15mL of bupivacaine 0.25%) and (ii) the ISB group (n=30) in which the patients received US-guided ISB with 30mL of bupivacaine 0.25%. General anesthesia was administered to all patients. During the first 24h, the variables assessed were time to administer the anesthesia, duration of the analgesia, onset and duration of motor and sensory blockade, opioid consumption, cardiovascular stability, complications, and patient satisfaction. RESULTS Anesthesia induction took more time for the SSB+SCB group than for the ISB group. However, the onset time of motor and sensory blockade was similar in the two groups. Statistical analysis of the visual analog postoperative pain scoring at H0, H6, H12, and H24 showed nonsignificant differences between the groups. Analgesia, the first request for morphine, and total morphine consumption during the first 24h was similar in both groups. No complication was recorded in the SSB+SCB group. However, phrenic nerve block occurred in all patients in the ISB group. CONCLUSION US-guided SCB combined with US-guided SSB was as effective as ISB for postoperative analgesia after shoulder instability surgery without decreasing potential side effects.

Abstract
BACKGROUND Dexmedetomidine is a new α-2 receptor agonist with analgesic and sedative properties. We used dexmedetomidine along with ropivacaine for supraclavicular brachial plexus block. METHODS Eighty ASA grade I-II patients, 18-60 years old, scheduled for elective upper limb orthopaedic surgery under supraclavicular brachial plexus block, were included in this prospective study. The patients were randomly assigned to group R (ropivacaine alone) and group RD (ropivacaine and dexmedetomidine) (40 patients in each group). Group R received ropivacaine 0.50% (30 cc)+placebo and group RD received ropivacaine 0.50% (30 cc)+dexmedetomidine 1 μg/kg. Primary outcome measure was duration of analgesia. Secondary measures were onset and duration of sensory blockade, pain scores, onset and duration of motor blockade, and evidence of any adverse drug reactions. RESULTS There was no significant difference hemodynamic parameter during intra-operative period. Group RD showed a statistically significant shorter time to onset of sensory blockade (10.75±2.71 vs. 16.75±2.96 min, P=.003), longer sensory block duration (379.40±55.09 vs. 211.60±47.88 min, P=.002), shorter onset time to motor blockade (14.35±2.58 vs. 20.25±4.13 min, P=.003), longer motor block duration (312.0±49.91 vs. 184.7±36.76 min, P=.002), longer duration of postoperative analgesia (413.73±89.92 vs. 197.35±28.67 min, P=.002). Three patients in the group RD developed somnolence. (P=.04). CONCLUSION Dexmedetomidine along with ropivacaine decreases the onset of motor and sensory block and increases the duration of sensory and motor block in supraclavicular brachial plexus block.

Abstract
OBJECTIVE In Britain, consent for surgery is documented using a Department of Health form signed by the surgeon and the patient. In contrast, anaesthetic procedures have no formalised consent process. Evidence on the process of consent for regional anaesthesia, and patient perceptions of this, is scarce outside obstetric practice. We aimed to determine patient recall and perceptions of consent for interscalene brachial plexus block and compared this to surgical consent for shoulder arthroplasty. DESIGN Prospective observational survey. SETTING A specialist musculoskeletal centre, UK. PARTICIPANTS Forty-six patients (female:male 30:16, mean age 61 years) undergoing shoulder arthroplasty with interscalene brachial plexus block. MAIN OUTCOME MEASURES Recall and understanding of consent for regional anaesthesia and surgery was examined using a semi-structured questionnaire 1-2 days after arthroplasty. Surgical consent forms and discussions recorded by the anaesthetist were examined in participants' medical notes to compare against the level of recall. Analysis to determine statistical significance was conducted using McNemar's test. RESULTS Recall of surgical risks was overall significantly better than recall of brachial plexus block risks. Compared to their recollections of surgical risk, patients remembered fewer specific risks for brachial plexus block (p < 0.001). There were more patients unable to recall any risks when questioned about brachial plexus block than about their surgery (p < 0.05). One-third of patients did not regard the consent discussion about regional anaesthesia as important as consent for surgery and over one-quarter had not recognised the preoperative discussion about the brachial plexus block as a consent process similar to that conducted for surgery. CONCLUSIONS Fundamental misunderstandings about the consent process are prevalent. Future work in this area should seek to investigate how documentation of the consent process and patients' understanding of consent for regional anaesthesia can be improved.

Abstract
OBJECTIVE To observe the anesthetic efficacy and safety of bilateral ultrasound-guided supraclavicular brachial plexus block in patients undergoing arthrolysis for shoulder periarthritis. METHODS Twenty-seven patients (ASA class I-II) undergoing bilateral shoulder joint release surgery and 24 ml received bilateral ultrasound-guided supraclavicular brachial plexus block anesthesia with 0.4% ropivacaine and 0.8% lidocaine. The visual analogue scale (VAS) scores for shoulder joint pain were recorded before and after anesthesia. The efficacy of axillary nerve, dorsal scapular nerve and suprascapular nerve block was evaluated, and the anesthetic effect and complications was assessed during surgery. Before and after anesthesia, the range of left and right diaphragmatic muscle movement was measured when the patient took a quiet breath and a deep breath. RESULTS The patients showed no significant variations in MAP, HR, or SpO₂after anesthesia. The VAS scores of shoulder joint pain during anteflexion, abduction, posterior extension, rotation, posterior extension and medial rotation were significantly lowered after anesthesia (P<0.05), but the left and the right diaphragm movement range showed no significant difference between quiet breath and deep breath (P>0.05). The rates of complete block of the axillary nerve and dorsal scapular nerve was 100%, and that of suprascapular nerve was 92.6%. Partial phrenic nerve block occurred in 1 case with mild local anesthetic toxicity in another. CONCLUSIONS Bilateral ultrasound-guided supraclavicular brachial plexus block in patients has excellent analgesic effect in should joint release surgery with good safely.
