Abstract
Interscalene nerve block (ISB) is an effective and low-risk local anesthetic (LA) procedure that is commonly employed for shoulder surgery. While phrenic nerve involvement occurs to some degree in every ISB procedure, the incidence of hypoxemia and other clinical signs of diaphragmatic disruption is much lower. This is a case of a 36-year-old female with no underlying respiratory disease who developed hypoxemia requiring a night of observation following an ISB for a rotator cuff repair procedure in an ambulatory surgical center. Her hypoxemia was easily treated with supplemental oxygen and she made a full recovery by the next day. The use of ultrasound guidance, reduced LA volume, less potent medication, sterile fluid for optimal visualization, and extrafascial administration should be considered for all patients receiving an ISB to prevent respiratory complications.

Intravenous Tranexamic Acid Improves Visual Clarity During Synovectomy in Patients Undergoing Arthroscopic Rotator Cuff Repair: A Double-Blind, Randomized Controlled Study. Arthroscopy 2024; 40:1409-1419. [PMID: 37890542 DOI: 10.1016/j.arthro.2023.10.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 10/10/2023] [Accepted: 10/10/2023] [Indexed: 10/29/2023]
Abstract
PURPOSE To assess the effects of intravenous tranexamic acid (TXA) on visual clarity at various surgical stages and the correlation between the severity of synovitis and bursitis and the grade of visual clarity in patients undergoing arthroscopic shoulder surgery under an interscalene brachial plexus block. METHODS This double-blind, randomized controlled study included patients undergoing arthroscopic rotator cuff repair. The TXA group underwent injection of a 100-mL mixture of 1,000 mg of TXA and normal saline solution intravenously whereas the control group was administered the same volume of normal saline solution at 10 minutes preoperatively. Visual clarity was rated according to a 3-grade visual clarity scoring system from grade 1 (clear) to grade 3 (poor) at 4 surgical stages (I, intra-articular soft-tissue procedures including synovectomy; II, acromioplasty; III, bursectomy; and IV, greater tuberoplasty). The primary outcome was arthroscopic visual clarity. The secondary outcomes were medications administered for hemodynamic stability, length of hospital stay, and thromboembolic events. RESULTS Altogether, 63 patients were included in the study; they were divided into the TXA group, comprising 32 patients, and the control group, comprising 31 patients. The TXA group showed significantly better visual clarity than the control group (median [interquartile range], 1 [1-2] vs 2 [1-2]; P = .027) during stage I but not during stages II through IV. Spearman correlation analysis revealed a significant correlation between synovitis and visual clarity grade during synovectomy (correlation coefficient, 0.393; P = .001) but not between bursitis and visual clarity grade during bursectomy. Deep vein thrombosis and pulmonary embolism did not occur in either group. CONCLUSIONS Intravenous TXA can improve visual clarity during intra-articular soft-tissue procedures, including synovectomy. However, it does not have a significant effect during acromioplasty, bursectomy, and greater tuberoplasty. TXA can be used to improve visual clarity in patients with suspected severe synovitis. LEVEL OF EVIDENCE Level I, randomized controlled trial.

Abstract
PURPOSE Evaluating the short- and long-term efficacy of a continuous ten day suprascapular nerve block combined with daily multidisciplinary rehabilitation on shoulder range of motion (ROM), pain, and function in patients with refractory adhesive capsulitis (AC). METHODS In this retrospective cohort study, patients admitted to a specialized pain clinic for refractory AC for more than 6 months underwent continuous suprascapular nerve blockade for ten days and received 2 hours of physiotherapy and occupational therapy daily. Standardized assessments were performed at baseline, at days three, six, ten, 30, 90, and 180, and included active and passive ROM measurements, the visual analog scale (VAS) for pain and the disabilities of the arm, shoulder and hand (DASH) questionnaire to assess pain, disability, and quality of life. Improvements over time were assessed using ANOVAs. RESULTS Thirty-two patients were followed (age: 52 ± 8 years, 25 females, mean symptoms duration of two years). There was a significant improvement in ROM for all amplitudes at day ten (short-term; range: 20-35°, p < 0.001) and at day 180 (long-term; range: 18-47°, p < 0.001). The pain and disability scores significantly reduced by day 180 (mean VAS reduction: 2.6 units, p < 0.001; mean DASH reduction: 9.5 points, p < 0.001). CONCLUSION Continuous SSNB combined with intensive multidisciplinary rehabilitation represents an efficient therapeutic option for patients with chronic AC who did not respond to conventional treatments.

MEDICINA (KAUNAS, LITHUANIA) 2024; 60:233. [PMID: 38399521 PMCID: PMC10890524 DOI: 10.3390/medicina60020233] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/31/2023] [Revised: 01/20/2024] [Accepted: 01/24/2024] [Indexed: 02/25/2024]
Abstract
Brachial plexus blocks at the interscalene level are frequently chosen by physicians and recommended by textbooks for providing regional anesthesia and analgesia to patients scheduled for shoulder surgery. Published data concerning interscalene single-injection or continuous brachial plexus blocks report good analgesic effects. The principle of interscalene catheters is to extend analgesia beyond the duration of the local anesthetic's effect through continuous infusion, as opposed to a single injection. However, in addition to the recognized beneficial effects of interscalene blocks, whether administered as a single injection or through a catheter, there have been reports of consequences ranging from minor side effects to severe, life-threatening complications. Both can be simply explained by direct mispuncture, as well as undesired local anesthetic spread or misplaced catheters. In particular, catheters pose a high risk when advanced or placed uncontrollably, a fact confirmed by reports of fatal outcomes. Secondary catheter dislocations explain side effects or loss of effectiveness that may occur hours or days after the initial correct function has been observed. From an anatomical and physiological perspective, this appears logical: the catheter tip must be placed near the plexus in an anatomically tight and confined space. Thus, the catheter's position may be altered with the movement of the neck or shoulder, e.g., during physiotherapy. The safe use of interscalene catheters is therefore a balance between high analgesia quality and the control of side effects and complications, much like the passage between Scylla and Charybdis. We are convinced that the anatomical basis crucial for the brachial plexus block procedure at the interscalene level is not sufficiently depicted in the common regional anesthesia literature or textbooks. We would like to provide a comprehensive anatomical survey of the lateral neck, with special attention paid to the safe placement of interscalene catheters.

Abstract
Background To compare the analgesic effect of ISB with a combination of ISB-SSNB and patients who were given opioids with PCA without block in adult patients undergoing shoulder surgery, as measured by opioid consumption and pain intensity in the first 24 hours postoperatively. Methods Ninety patients who underwent shoulder surgery were randomly divided into three groups. Group I in which ISB was performed and patient-controlled analgesia (PCA) was inserted, Group II with; ISB and SSNB combined, and PCA was inserted, and Group III where; only PCA was used. Visual analog scale (VAS) pain scores at the second, fourth, sixth, 12th, and 24th hours, morphine consumption, additional analgesic requirement, and patient satisfaction were evaluated. Results Compared with Group III, the VAS pain score was significantly lower in Group I and Group II at 2, 4, 6, 12, and 24 hours postoperatively. In Group I, the VAS score at rest at the 6th hour was found to be higher than in Group II. The 24-hour total morphine consumption was higher in the control group than in Group I and Group II. The satisfaction score of the control group was lower than Group I and Group II. Conclusion The combined application of ISB and SSNB block is beneficial in shoulder surgery to provide both intraoperative and postoperative analgesia and opioid consumption.

Analgesic efficacy and safety of erector spinae versus serratus anterior plane block in thoracic surgery: a systematic review and meta-analysis of randomized controlled trials.

Abstract
BACKGROUND Erector spinae plane block (ESPB) and serratus anterior plane block (SAPB) are regional anesthesia techniques that have shown favorable results in pain management following thoracic surgeries; however, their relative superiority is unclear. This review (PROSPERO: CRD42023443018) aims to compare the analgesic efficacy of ESPB and SAPB in patients undergoing thoracic surgeries through the pooled analysis of co-primary outcomes: postoperative oral-morphine-equivalent (mg) consumption in 24 h and pain scores (static) at 24 h. METHODS A literature search was conducted across PubMed, Cochrane Library, and Google Scholar to identify randomized controlled trials (RCTs) from inception to May 2023, comparing ESPB and SAPB in thoracic surgeries. Statistical pooling was done using Review Manager 5.4.1. Bias assessment employed the Cochrane Collaboration Risk-of-Bias 2.0 tool. The strength of evidence was assessed using the guidelines from the GRADE working group. RESULTS Nine RCTs (485 patients) were included in the study. Postoperative pain scores (static) at 24 h (mean difference (MD) = - 0.31 [- 0.57, 0.05], p = 0.02) and postoperative oral-morphine-equivalent (mg) consumption in 24 h (MD = - 19.73 [- 25.65, - 13.80], p < 0.00001) were significantly lower in the ESBP group. However, the MDs did not exceed the set threshold for clinical importance. No significant differences were observed in the opioid-related adverse effects and block-related complications. CONCLUSION Our statistically significant results imply that ESPB has superior analgesic efficacy compared to SAPB; however, this difference is clinically unimportant. The safety profile of the two blocks is comparable; hence, current evidence cannot define the relative superiority of one block over the other. Our findings warrant further research with standardized methodologies and a longer duration of analgesic efficacy assessment to yield robust evidence for better clinical applications.

Abstract
BACKGROUND Combined suprascapular and axillary nerve block could be an analgesic option for shoulder pain control. The current description of this technique requires performing the block procedures at two different sites without consideration for catheter placement. We hypothesized that a single site injection to the interfascial plane between the infraspinatus and teres minor would result in an injectate spread to the suprascapular and axillary nerves. METHODS We performed 10 injections with this approach using 25 mL dye solution in 10 shoulders of five unembalmed cadavers. Also, we described three case reports, two single-injection cases and one catheter-placement case, using this approach in patients with acute postsurgical pain and chronic pain in their shoulder region. RESULTS In cadaveric evaluations, dye spreading to the suprascapular nerves on the infraspinatus fossa and the spinoglenoid notch cephalad and axillary nerves in the quadrilateral space caudally were observed in all injections. In addition, the most posterolateral part of the joint capsule was stained in 8 out of 10 injections. There was no dye spreading on the nerves to the subscapularis or lateral pectoral nerves. Clinically successful analgesia with no adverse events was achieved in all three cases. CONCLUSION Our anatomical and clinical observations demonstrated that an injection to the interfascial plane between the infraspinatus and teres minor consistently achieved injectate spreading to both suprascapular and axillary nerves, which innervate the glenohumeral joint.

Abstract
BACKGROUND Shoulder dislocations are among the most common orthopedic emergencies encountered in the emergency department (ED). Ultrasound-guided peripheral nerve blocks (USG-PNBs) are increasingly being used for acute pain management in the ED, but clinical evidence supporting their utility for shoulder dislocation is limited and often conflicting. OBJECTIVE The aim of this review was to summarize and evaluate the utility of USG-PNB for analgesia during closed reduction of dislocated shoulders in the ED. METHODS Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic literature search of the PubMed, Scopus, and Cochrane databases was performed from database inception to September 2022. We included clinical studies examining USG-PNB for pain management of dislocated shoulders in the ED. Information collected from eligible studies included patient demographic characteristics, USG-PNB approach, alternate analgesia techniques, anesthetic regimens, clinical outcomes, and adverse events. RESULTS Five studies met inclusion criteria, all of which were randomized controlled trials comparing USG-PNB with procedural sedation and analgesia. Pooled patient satisfaction scores were similar for both analgesia methods (3.5 ± 0.6 vs. 3.9 ± 0.6 out of 5; p = 0.76). Patients managed with procedural sedation and analgesia achieved higher rates of overall shoulder reduction (100% vs. 67%; p < 0.001) and successful reduction on the first attempt (86% vs. 48%; p < 0.001). The USG-PNB groups in all but one study had shorter lengths of ED stay. Overall, USG-PNB was associated with a lower risk of adverse events and complications (3.9% vs. 24.9%; p < 0.001), especially adverse respiratory events (0% vs. 14.7%; p < 0.001). CONCLUSIONS USG-PNBs performed by adequately trained emergency physicians should be considered a safe and effective alternative for analgesia during closed reduction of dislocated shoulders in the ED, particularly in patients with cardiorespiratory comorbidities.

Abstract
Distal third clavicle fractures are a frequent pathology in young, active patients, accounting for 30% of all clavicle fractures. There are several treatments available, which range from orthopedic management to surgical treatment with various options including: locking plates, tension bands and button fixation. The aim of this study was to evaluate the clinical and radiologic results of a group of patients treated with the arthroscopic double button fixation technique and, secondly, to analyze the complications and the rate of return to sports. METHODS Nineteen patients (15 male and 4 Female) with a mean age of 38.2 years (21-64) were included. In all cases, an arthroscopic surgery with double button fixation of the distal third of the clavicle was performed. Functional Outcomes were evaluated with the visual analog scale (VAS) for pain, the American Shoulder and Elbow Surgeons scale (ASES) for functional outcomes. Range of Motion (ROM) was also assessed. RESULTS The mean follow up was 27.3 months (12 to 54 months). The mean VAS was 0.63 and the mean ASES score was 94.1. The ROM was fully recovered in 17 patients (89,4%). All patients returned to regular sports practice at 3.5 months. Finally, a total of 2 complications were registered (11,6%). CONCLUSION The arthroscopic double button fixation of distal clavicular fractures is a safety and reliable procedure, and it is associated with favorable functional and radiological outcomes in most patients.

Abstract
The interscalene block (ISB) is the standard regional anesthesia for shoulder arthroscopy. However, the superior trunk block (STB) is an alternative with a potentially safer profile. This meta-analysis aimed to compare the incidence and degree of hemidiaphragmatic paralysis and block efficacy of these techniques. We searched MEDLINE, EMBASE, Scopus, and Cochrane databases to identify randomized controlled trials (RCTs). The main outcome was total hemidiaphragmatic paralysis. We used the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) framework to assess the certainty of evidence. Four RCTs and 359 patients were included. The STB group showed lower total hemidiaphragmatic paralysis (RR 0.07; 95% CI 0.04 to 0.14; p<0.0001). The incidence of subjective dyspnea (p = 0.002) and Horner's syndrome (p<0.001) was significantly lower with STB relative to ISB. There was no significant difference between groups in block duration (p = 0.67). There was a high certainty of evidence in the main outcome as per the GRADE framework. Our findings suggest that STB has a better safety profile than ISB, resulting in lower rates of hemidiaphragmatic paralysis and dyspnea while providing a similar block. Therefore, STB could be preferred to ISB, especially in patients susceptible to phrenic nerve paralysis complications.

Effects of the costoclavicular block versus interscalene block in patients undergoing arthroscopic shoulder surgery under monitored anesthesia care: a randomized, prospective, non-inferiority study. Korean J Anesthesiol 2023; 76:413-423. [PMID: 36617951 PMCID: PMC10562073 DOI: 10.4097/kja.22638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 01/01/2023] [Accepted: 01/06/2023] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Recent studies have reported that costoclavicular blocks (CCBs) can consistently block almost all branches of the brachial plexus while sparing the phrenic nerve and provide effective analgesia after shoulder surgery. We aimed to compare the efficacy of the CCB with that of the interscalene block (ISB) as the sole blocking technique for shoulder surgery. METHODS A total of 212 patients undergoing elective arthroscopic shoulder surgery were randomized to receive an ISB or CCB based on a non-inferiority design. All patients received titration sedation with propofol under monitored anesthesia during surgery. The primary outcomes were the proportion of patients with complete motor blockade of the suprascapular nerve (SSN) and incidence of hemidiaphragmatic paralysis (HDP). The secondary outcomes included block-related variables, complications, and postoperative pain scores. RESULTS The proportion of patients with complete motor blockade of the SSN at 20 min between the CCB and ISB groups (53% vs. 66%) exceeded the predefined non-inferiority margin of -5%, but was comparable at 30 min (87% vs. 91%). The CCB resulted in a significantly lower incidence of HDP (7.55% vs. 92.45%), Horner's syndrome (0% vs. 18.87%), and dyspnea (0% vs. 10.38%) than the ISB. None of the patients experienced failed blocks or required conversion to general anesthesia. Pain scores were comparable between the groups. CONCLUSIONS Ultrasound-guided CCBs may be comparable to ISBs, with fewer unfavorable complications in patients with impaired lung function undergoing arthroscopic shoulder surgery.

[PMID: 37727810 PMCID: PMC10506885 DOI: 10.1155/2023/9962595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 07/19/2023] [Accepted: 08/06/2023] [Indexed: 09/21/2023] Open
Abstract
Peripheral nerve blocks are an increasingly common method of providing postoperative analgesia for shoulder surgeries. However, the standard technique, the interscalene block (ISB), inevitably causes hemidiaphragmatic paresis (HDP), secondary to phrenic nerve palsy. This can cause morbidity in patients with preexisting respiratory compromise, prompting investigation into alternative "phrenic-sparing" nerve blocks. The aim of this review was to give an overview of these blocks and critically evaluate the current literature to determine if any are suitable replacements for ISB. The incidence of HDP and analgesic efficacy were considered. We queried four electronic databases and one register. Twenty-eight original articles were selected for review. The use of ultrasound guidance, lower volumes of local anaesthetic (LA), and injection 4 mm outside the brachial plexus fascia reduced HDP incidence for the ISB; however, no single modification did so sufficiently. While the anterior suprascapular nerve block (SSNB) showed comparable analgesic effects to the ISB, HDP prevalence was also high. The posterior SSNB produced consistently low HDP incidences but also inferior analgesia to ISB, except when combined with an infraclavicular brachial plexus block. The superior trunk block (STB) provided equivalent analgesia to the ISB while reducing HDP incidence, but not significantly. Lower LA volumes consistently led to lower HDP incidence across all blocks, likely due to a reduced ability to spread to the phrenic nerve. Further investigation into the minimum effective volumes of the extrafascial ISB, anterior SSNB, STB, and combined posterior SSNB with infraclavicular block is warranted to determine if any of these blocks can successfully balance HDP prevention with analgesic efficacy.

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. [PMID: 37652809 DOI: 10.1016/j.jemermed.2023.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 05/08/2023] [Accepted: 05/26/2023] [Indexed: 09/02/2023]
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
Frailty is a complex and multisystem biological process characterized by reductions in physiological reserve. It is an increasingly common phenomena in the surgical population, and significantly impacts postoperative recovery. In this review, we will discuss the pathophysiology of frailty, as well as preoperative, intraoperative, and postoperative considerations for frailty care. We will also discuss the different models of postoperative care, including enhanced recovery pathways, as well as elective critical care admission. With discoveries of new effective interventions, and advances in healthcare information technology, optimized pathways could be developed to provide the best care possible that meets the challenges of perioperative frailty.

Abstract
Purpose The aim of this study was to evaluate the occurrence of early (<6 weeks) post-operative complications following ulnar nerve decompressions at the cubital tunnel performed under regional anesthesia compared to those performed under general anesthesia. Methods In situ ulnar nerve decompressions at the cubital tunnel performed at a single institution from 2012 through 2019 were retrospectively reviewed. Post-operative complications were compared between subjects who underwent the procedure with regional versus general anesthesia. Results Ninety-one ulnar nerve in situ decompressions were included in the study, which were performed under regional anesthesia in 55 and general anesthesia in 36 cases. The occurrence of post-operative complications was not significantly different between patients who received regional (n = 7) anesthesia and general (n = 8) anesthesia. None of the complications were directly attributed to the type of anesthesia administered. The change in pre- and post-operative McGowan scores were not significantly different between anesthesia groups (p = 0.81). Conclusion In situ ulnar nerve decompression at the cubital tunnel under regional anesthesia does not result in increased post-operative complications compared to those surgeries performed under general anesthesia. In situ ulnar nerve decompression performed under regional anesthesia is a safe and reliable option for patients who wish to avoid general anesthesia. Level of Evidence III.

Abstract
Background This review aims to compare the outcomes for day case shoulder replacement with in-patient shoulder replacement surgery in a district general hospital. Methods Seventy-three patients had 82 shoulder arthroplasty procedures. Forty-six procedures were undertaken in a dedicated stand-alone day-case unit and 36 were undertaken as in-patient cases. Patient were followed up at 6 weeks, 6 months and annually. Results There was no significant difference between the outcomes of shoulder arthroplasty procedures performed in the day case or in-patient settings making this a safe option for surgical care in a unit with an appropriate care pathway. Six complications in total were observed, three in each group. Operation time was statistically shorter for day cases by 25.1 min (95% CI - 36.5 to -13.7; d = -0.95, 95% CI -1.42 to 0.48). Estimated marginal means (EMM) revealed lower post-surgery oxford pain scores in day cases (EMM = 3.25, 95% CI 2.35, 4.16) compared with inpatients (EMM = 4.65, 95% CI 3.64 to 5.67). Constant shoulder scores were higher in day cases versus inpatients. Conclusion Day case shoulder replacement is safe with comparable outcomes to routine inpatient care for patients up to ASA 3 classification with high satisfaction and excellent functional outcomes.

Abstract
Background The use of regional anesthesia in shoulder arthroscopy improves perioperative pain control, thereby reducing the need for opioids and their recognized side effects. Occasionally one type of block is not suitable for a patient's anatomy or comorbidities or requires a specially trained anesthetist to safely perform. The primary aim of this study is to compare the efficacy of 3 different nerve blocks for pain management in patients undergoing shoulder arthroscopy. Methods A 3-arm, blinded, randomized controlled trial in patients undergoing elective, unilateral shoulder arthroscopic procedures between August 2018 and November 2020 was conducted at a single center. One hundred and thirty participants were randomized into 1 of 3 regional anesthesia techniques. The first group received an ultrasound-guided interscalene block performed by an anesthetist (US + ISB). The second group received an ultrasound-guided suprascapular nerve block and an axillary nerve block by an anesthetist (US + SSANB). The final group received a suprascapular nerve block without ultrasound and an axillary nerve block under arthroscopic guidance by an orthopedic surgeon (A + SSANB). Intraoperative pain response, analgesia requirements, and side effects were recorded. Visual analogue pain scores and opioid doses were recorded in the Post Anaesthesia Care Unit (PACU) and daily for 8 days following the procedure. Results Twelve patients withdrew from the study after randomization, leaving 39 participants in US + ISB, 40 in US + SSANB, and 39 in A + SSANB. The US + ISB group required significantly lower intraoperative opioid doses than US + SSANB and A + SSANB (P < .001) and postoperatively in PACU (P < .001). After discharge from hospital, there were no differences between all groups in daily analgesia requirements (P = .063). There was significantly more nerve complications with 6 patient-reported complications in the US + ISB group (P = .02). There were no reported differences in satisfaction rates between groups (P = .41); however, the A + SSANB group was more likely to report a wish to not have a regional anesthetic again (P = .04). Conclusion The US + ISB group required lower opioid doses perioperatively; however, there was no difference between groups after discharge from PACU. The analgesia requirements between the US + SSANB and A + SSANB were similar intraoperatively and postoperatively. A surgeon-administered SSANB may be a viable alternative when an experienced regional anesthetist is not available.

Abstract
Purpose Ultrasound-guided interscalene nerve block (UISB) is commonly used to alleviate postoperative pain during shoulder arthroscopy. This retrospective observational study aimed to evaluate the intraoperative advantages and analgesic effects of preoperative UISB. Patients and Methods In this retrospective observational study, a total of 170 patients underwent shoulder arthroscopy at a tertiary medical center in southern Taiwan throughout 2019. After applying the exclusion criteria, 142 of these cases were included, with 74 and 68 in the UISB group and control groups, respectively. The primary outcome was the evaluation of intraoperative morphine milligram equivalent (MME) consumption. Secondary outcomes were sevoflurane consumption, the use of intraoperative antihypertensive drugs, and postoperative visual analog scale (VAS) scores in the post-anesthesia care unit (PACU) and in the ward at 24 h after surgery. Results Preoperative UISB effectively reduced opioids and volatile gases during surgery, supported by a 48.1% and 14.8% reduction in the median intraoperative MME and sevoflurane concentrations, respectively, and showed less need for antihypertensive drugs. The preoperative UISB group also showed significantly better performance on the VAS in both the PACU and ward. Conclusion Taken together, the preoperative UISB reduced not only intraoperative MME and sevoflurane consumption but also had satisfactory VAS scores in both the PACU and ward without any symptomatic respiratory complications. In summary, preoperative UISB is a reliable adjuvant analgesic technique and a key factor in achieving opioid-sparing and sevoflurane-sparing anesthesia and multimodal analgesia during shoulder arthroscopy.

Abstract
BACKROUND The supraclavicular plexus block (SCB) and interscalene plexus block (ISB) have the potential to pulmonary function, the duration of the potential remains uncertain. So, we compared the effect of SCB and ISB on pulmonary function, especially the duration time. METHODS Ninety-six patients were finally allocated to group I and group S. The ISB and the SCB procedures were performed with ultrasound guidance before anesthesia induction. An investigator recorded the diaphragm mobility and respiratory function test indicators before the block (T0) and at 30 min (T30 min), 4 h (T4), 8 h (T8), and 12 h (T12) after the block. The diaphragmatic paralysis rate was calculated for above timepoint. The VAS, the recovery time for the sensory and motor block, and adverse reactions within 24 h of administering the block were also recorded. RESULTS The recovery times of diaphragm mobility in group I were longer than those in group S. Compared with group I, group S had a significantly lower diaphragmatic paralysis rate during eupnea breathing at T30 min and T8 after the block. Similarly, group S had a significantly lower diaphragmatic paralysis rate at deep breathing at T30 min, T8, and T12 after the block. The recovery times of FEV1 and FVC in group I were longer than those in group S. The other results were not statistically significant. CONCLUSIONS Ultrasound-guided ISB resulted in a longer periods with a suppressive effect on pulmonary function than SCB. TRIALS REGISTRATION 17/12/2019, ChiCTR1900028286.

Abstract
Introduction Regional anesthesia (RA) is used reduce pain in proximal humerus and humeral shaft fracture surgery. The study hypothesis was that RA would decrease opioid demand in patients undergoing fracture surgery. Materials and methods Opioid demand was recorded in all patients ages 18 and older undergoing proximal humerus or humeral shaft fracture surgery at a single, Level I trauma center from 7/2013 - 7/2018 (n = 380 patients). Inpatient opioid consumption from 0-24, 24-48, and 48-72 h and outpatient opioid demand from 1-month pre-operative to 90-days post-operative were converted to oxycodone 5-mg equivalents (OE's). Unadjusted and adjusted models were constructed to evaluate the impact of RA and other factors on opioid utilization. Results Adjusted models demonstrated increases in inpatient opioid consumption in patients with RA (6.8 estimated OE's without RA vs 8.8 estimated OE's with RA from 0-24 h post-op; 10 vs 13.7 from 24-48 h post-op; and 8.7 vs 11.6 from 48-72 h post-op; all p < 0.05). Estimated cumulative outpatient opioid demand was significantly higher in patients with RA at all timepoints. Discussion In proximal humerus and humeral shaft fracture surgery, RA was associated with increased inpatient and outpatient opioid demand after adjusting for baseline patient and treatment characteristics.

An alternative approach for blocking the superior trunk of the brachial plexus evaluated by a single arm clinical trial. BRAZILIAN JOURNAL OF ANESTHESIOLOGY (ELSEVIER) 2022; 72:774-779.

Abstract
BACKGROUND Interscalene brachial plexus block is associated with phrenic nerve paralysis. The objective of this study was to evaluate an alternative approach to interscalene brachial plexus blocks in terms of efficacy, grade of motor and sensory blockade, and phrenic nerve blockade. METHODS The study was prospective and interventional. The ten living patients studied were 18 to 65 years old, ASA physical status I or II, and submitted to correction of rotator cuff injury. A superior trunk blockade was performed at the superior trunk below the omohyoid muscle, without blocking the phrenic nerve. The needle was advanced below the prevertebral layer until contacting the superior trunk. In order to guarantee the correct positioning of the needle tip, an intracluster pattern of the spread was visualized. The block was performed with 5.ßmL of 0.5% bupivacaine in ten patients. In the six cadavers, 5.ßmL of methylene blue was injected. Diaphragmatic excursion was assessed by ultrasonography of the ipsilateral hemidiaphragm. In three patients, pulmonary ventilation was evaluated with impedance tomography. Pain scores and analgesic consumption were assessed in the recovery room for 6.ßhours after the blockade. RESULTS In the six cadavers, methylene blue didn...t reach the phrenic nerve. Ten patients underwent arthroscopic surgery, and no clinically phrenic nerve paralysis was observed. No patient reported pain during the first 6.ßhours. CONCLUSIONS This study suggests that this new superior trunk approach to block the superior trunk may be an alternative technique to promote analgesia for shoulder surgery in patients with impaired respiratory function.

Abstract
Purpose
Dexmedetomidine has been proposed as an additive to local anesthetics to prolong peripheral nerve block duration; however, perineural dexmedetomidine has been associated with an increased risk of bradycardia and hypotension This randomized controlled study investigated the effects of low-dose dexmedetomidine as a perineural adjuvant for postoperative analgesia. Methods Fifty-five patients who had undergone elective upper extremity surgery were randomized to receive an ultrasound-guided supraclavicular brachial plexus block with 20 mL 0.5% ropivacaine with or without 30 μg dexmedetomidine. The primary outcome was the duration of analgesia. Secondary outcomes included the onset time and duration of the motor and sensory blocks, incidence of hypotension and bradycardia, total postoperative analgesics, and safety assessment during the 24 h after surgery. Results Dexmedetomidine significantly prolonged the duration of analgesia (887 ± 92 min vs 661 ± 83 min, P < 0.0001). The onset time and the duration of motor and sensory block were significantly different between the groups (all P < 0.001). No episodes of hypotension or bradycardia were detected in the dexmedetomidine group. The total postoperative analgesic use and side effect profiles in the first 24 h postoperative period were similar for both groups. Conclusions Low-dose dexmedetomidine (30 μg) as a perineural adjuvant significantly prolonged the analgesic duration of a brachial plexus block without inducing hemodynamic instability.

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
(1) Background: Suprascapular neuropathy is an important factor contributing to shoulder pain. Given the prevalence of nerve injury and nerve block in the suprascapular notch region, as well as the frequency of arthroscopic procedures on the suprascapular notch, which are recommended in shoulder pain management, its morphology is relevant from a clinical perspective. (2) Methods: Suprascapular nerve course was studied in twelve shoulders by dissection. Its diameter was measured at omohyoid level, proximal to the suprascapular notch and distal to the spinoglenoid notch. A multi-vari chart was used in order to descriptively visualize the results. The variations found were analyzed with a mixed linear model. (3) Results: In two of the six subjects, the suprascapular nerve was divided into two motor branches proximal to the superior transverse scapular ligament. An increase in diameter around the suprascapular notch was detected, with an estimated difference between diameter means of 2.008 mm at the suprascapular notch level and 2.047 mm at the spinoglenoid notch level. (4) Conclusions: A difference in the estimated diameter detected and the fact that the motor branches, which innervate supraspinatus and infraspinatus muscle, were divided proximal to the suprascapular notch may be relevant in the diagnosis and treatment of suprascapular neuropathy and arthroscopic procedures.

Abstract
Background The innervation of the proximal humerus fracture is complicated and unclear. The use of interscalene nerve block has been effective as postoperative analgesia for patients, but the optimal concentration of usage is unknown. Method This study was conducted on 30 patients with ASA I or II, who were planning to undergo a proximal humerus fracture operation. A dosage of 10 ml Ropivacaine was administered for the interscalene brachial plexus block (ISBPB) as determined using the up-and-down sequential method. The initial concentration of Ropivacaine in the first patient to receive ISBPB was 0.3%. After a successful or unsuccessful postoperative analgesia, the concentration of local anesthetic was decreased or increased, respectively, by 0.05% in the next patient. We defined successful postoperative analgesia as a visual analog scale (VAS) score of < 4 at rest, within the initial 8 h after ISBPB. The analytic techniques of linear, linear-logarithmic, exponential regressions, and centered isotonic regression were used to determine the EC50 of Ropivacaine, and the residual standard errors were calculated for the comparison of “goodness of fit.” Results The concentration of Ropivacaine ranged from 0.1 to 0.35%. The EC50 (95% confidence interval) from 4 different statistical approaches (linear, linear-logarithmic, exponential regressions, and centered isotonic regression) were 0.222% (0.198%, 0.335%), 0.233% (0.215%, 0.453%), 0.223% (0.202%, 0.436%), and 0.232%, respectively. Among all the 4 models, the linear regression had the least residual standard error (0.1676). Conclusion The EC50 from the four statistical models for 10 ml Ropivacaine in ultrasound-guided ISBPB for postoperative analgesia was distributed in a narrow range of 0.222–0.233%.

Abstract
PURPOSE The high-thoracic erector spinae plane block (HT-ESPB) has been reported as an effective analgesic modality for the shoulder region without phrenic nerve palsy. The goal of this study was to compare the HT-ESPB as a phrenic nerve-sparing alternative to an interscalene block for total shoulder arthroplasty. METHODS Thirty patients undergoing total shoulder arthroplasty at Stanford Health Care (Palo Alto, CA, USA) were enrolled in a double-blind randomized controlled trial. We randomized 28 patients to receive either an interscalene or HT-ESPB perineural catheter preoperatively; 26 patients were included in the final analysis. The study was powered for the primary outcome of incidence of hemidiaphragmatic paralysis in the postanesthesia care unit (PACU). Other outcome measures included incentive spirometry volume, brachial plexus motor and sensory exams, adverse events, pain scores, and opioid consumption. RESULTS The incidence of hemidiaphragmatic paralysis in the HT-ESPB catheter group was significantly lower than in the interscalene catheter group (0/12, 0% vs 14/14, 100%; P < 0.001). No statistically significant differences were found in pain scores and opioid consumption (in oral morphine equivalents) between the interscalene and HT-ESPB groups through postoperative day (POD) 2. Nevertheless, the mean (standard deviation) point estimates for opioid consumption for the HT-ESPB group were higher than for the interscalene group in the PACU (HT-ESPB: 24.8 [26.7] mg; interscalene: 10.7 [21.7] mg) and for POD 0 (HT-ESPB: 20.5 [25.0] mg; interscalene: 6.7 [12.0] mg). In addition, cumulative postoperative opioid consumption was significantly higher at POD 0 (PACU through POD 0) in the HT-ESPB group (45.3 [39.9] mg) than in the interscalene group (16.6 [21.9] mg; P = 0.04). CONCLUSIONS This study suggests that continuous HT-ESPB can be a phrenic nerve-sparing alternative to continuous interscalene brachial plexus blockade, although the latter provided superior opioid-sparing in the immediate postoperative period. This was a small sample size study, and further investigations powered to detect differences in analgesic and quality of recovery score endpoints are needed. STUDY REGISTRATION www.

Abstract
Regional anaesthesia should be the preferred technique for analgesia in shoulder surgery, which is a frequent procedure in the daily practice of anaesthesiologists. The use of ultrasound guidance enables the visualization of the relevant nerve structures and the adjacent anatomical details. Low volumes of local anaesthetics reduce the incidence of inadvertent blockade of the phrenic nerve with subsequent respiratory impairment. The additional administration of dexmedetomidine to local anaesthetics prolonges the duration of analgesia with a minimal increased incidence of haemodynamic side effects. An optimal workflow is associated with economical advantages due to an improved use of operation rooms. Attention have to be paid regarding intraoperative hypotension, cerebral hypoperfusion and complications due to positioning.

Abstract
INTRODUCTION The aim of this study is to verify if the shoulder anterior capsular block (SHAC), combined with other nerve blocks, is effective in relieving shoulder pain, avoiding motor block and allowing an early rehabilitation program. METHODS Seventy-five consecutive patients with painful shoulder were treated with the SHAC, alone (30 patients) or in combination with a suprascapular nerve block (SSnb: 25 patients) or with pectoralis and serratus plane block (PECS-2: 20 patients). All blocks were performed with 0.2% ropivacaine plus 8 mg dexamethasone. All patients were treated with three-weekly physiotherapy sessions for the following 2 weeks and then with home exercises. RESULTS The post-procedural analgesic effect was strong in all groups, with a mean change in numeric rating scale (NRS) values of -6.05 in group 1, -6.25 in group 2, and -6.19 in group 3 (p < .0001), allowing all patients to complete an immediate physiotherapy session. Only a few patients needed to repeat the procedure 1 week after the first treatment for the recurrence of pain. From the treatment to the end of the follow-up, we noted a further drop in mean pain NRS values of 1.90 in group 1 and 1.80 in groups 2 and 3. No difference in effect over time was observed among the different groups. No adverse event or motor block was recorded. CONCLUSION This study demonstrates that the SHAC, alone or in combination with other peripheral nerve blocks, is an attractive alternative for shoulder pain management, especially when physiotherapy is required to recover shoulder function.

Abstract
CASE We report the case of a 27-year-old man who presented after a 30-foot fall with a hemopneumothorax, multiple rib fractures, and left shoulder dislocation with greater tuberosity fracture. During attempted arthroscopic repair, the patient developed pulseless electrical activity arrest as the result of intraoperative tension hydrothorax. We hypothesize that this was caused by a traumatic soft-tissue communication to his shoulder joint from the apex of his lung. CONCLUSION To our knowledge, this is a unique and unreported complication of shoulder arthroscopy and should increase awareness about possibly delaying surgery in the setting of significant soft-tissue trauma.

J Shoulder Elbow Surg 2021; 30:2638-2647. [PMID: 34284094 DOI: 10.1016/j.jse.2021.06.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Revised: 05/29/2021] [Accepted: 06/07/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Postoperative pain management after total shoulder arthroplasty (TSA) can be challenging. Given the variety of pain management options available, the purpose of this investigation was to systematically review the literature for randomized controlled trials reporting on pain control after shoulder arthroplasty. We sought to determine which modalities are most effective in managing postoperative pain and reducing postoperative opioid use. METHODS A systematic review was performed using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched for Level I-II randomized controlled trials that compared interventions for postoperative pain control after TSA. Pain control measures included nerve blocks and nerve block adjuncts, local injections, patient-controlled analgesia, oral medications, and other modalities. The 2 primary outcome measures were pain level measured on a 0-10 visual analog scale and opioid use. The risk of study bias and methodologic quality were analyzed using The Cochrane Collaboration's Risk of Bias 2 (RoB 2) tool. Network meta-analyses were performed for visual analog scale pain scores at postsurgical time points and opioid use using a frequentist approach and random-effects model, with heterogeneity quantified using the I2 statistic. Treatments were ranked using the P score, and statistical significance was set at P < .05. RESULTS The initial search yielded 2391 articles (695 duplicates, 1696 screened, 53 undergoing full-text review). Eighteen articles (1358 shoulders; 51% female patients; mean age range, 65-73.7 years; 4 studies with low risk of bias, 12 with some risk, and 2 with high risk) were included and analyzed. At 4 and 8 hours postoperatively, patients receiving local liposomal bupivacaine (LB) injection (P < .001 for 4 and 8 hours) or local ropivacaine injection (P < .001 for 4 hours and P = .019 for 8 hours) had significantly more pain compared with patients who received either a continuous interscalene block (cISB) or single-shot interscalene block (ssISB). No differences in opioid use (at P < .05) were detected between modalities. The P scores of treatments demonstrated that ssISBs were most favorable at time points < 24 hours, whereas pain at 24 and 48 hours after surgery was best managed with cISBs or a combination of an ssISB with a local LB injection. CONCLUSION Interscalene blocks are superior to local injections alone at managing pain after TSA. Single-shot interscalene blocks are optimal for reducing early postoperative pain (< 24 hours), whereas pain at 24-48 hours after surgery may be best managed with cISBs or a combination of an ssISB with a local LB injection.

Abstract
Pneumomediastinum (PNM) and pneumothorax (PNX) are documented complications of arthroscopic shoulder surgery (ATS). Plexus anesthetic block and tracheal lesions during endotracheal intubation are hypothesized to be the underlying risk factors; however, the actual evidence supporting this hypothesis is scarce.A case of bilateral laterocervical emphysema, subcutaneous edema, and signs of PNM after ATS performed under general anesthesia and supra-scapular nerve block is presented. An up-to-date systematic review of PNM/PNX during orthopedic surgery was performed, involving six databases: PubMed (1996-present), Embase (1974-present), Scopus (2004-present), SpringerLink (1950-present), Ovid Emcare (1995-present), and Google Scholar (2004-present).Twenty-five case studies met the eligibility criteria. In 24 cases, the patient underwent general anesthesia and orotracheal intubation; in 9 of these, a plexus anesthetic block was also performed. One case involved ATS under plexus anesthetic block only. In 10 cases, the diagnostic finding was PNM. In 5 cases, the diagnostic finding was associated with PNX. PNX was detected in 17 cases. In 2 cases, SE was found in the absence of any evidence of either PNM or PNX. A tracheal lesion was identified in 3 cases.Endotracheal intubation and loco-regional anesthesia are not the only predisposing risk factors at play in the pathogenesis of PNM/PNX. Rather, multi-factorial pathogenesis seems more probable, necessitating that specific attention is paid during ATS to the change in patient position on the operating bed, to any slipping of the endotracheal tube, to patient monitoring whilst under the drapes, and to the cuff pressure. PROSPERO registration number: CRD42021260370.

Abstract
PURPOSE This randomized noninferiority trial aimed to evaluate whether combined suprascapular, axillary nerve, and the articular branch of lateral pectoral nerve block (3NB) is noninferior to interscalene nerve block (ISB) for pain control after arthroscopic rotator cuff repair (ASRCR). MATERIALS AND METHODS Eighty-five patients undergoing ASRCR were randomized to either 3NB (n = 43) or ISB (n = 42) group. We used 5 and 15 ml of 0.2% ropivacaine for each nerve in the 3NB and ISB groups, respectively. The primary outcome was the visual analog scale (VAS) pain score at 4 h postoperatively measured assessed on an 11-point scale (ranging from 0 = no pain to 10 = worst pain) that was analyzed using noninferiority testing. The secondary outcome was VAS pain scores in the recovery room and at 8, 12, 24, 36, 48, and 72 h postoperatively. Rebound pain, IV-PCA usage during 48 h, dyspnea, muscle weakness, and satisfaction were evaluated. RESULTS Regarding the primary outcome, the mean difference in VAS pain scores between the 3NB (2.5 ± 1.6) and ISB (2.2 ± 2.3) groups at 4 h postoperatively was 0.3, with a 95% confidence interval (CI) of -0.56 to 1.11. The upper limit of 95% CI is lower than the noninferiority margin of 1.3 (p < 0.001). At all other time points, except in the recovery room, 3NB showed noninferior to ISB. Rebound pain, IV-PCA usage during the second 24 h, and muscle weakness were lower in the 3NB group (all p < 0.005). The satisfaction was similar in both groups (p = 0.815). CONCLUSION Combined 3NB is noninferior to ISB in terms of pain control after ASRCR; and is associated with low levels of rebound pain, IV-PCA usage, and muscle weakness. LEVEL OF EVIDENCE Randomized controlled trial, Level I.

Abstract
Decompression of the suprascapular nerve (SSNe) at the suprascapular notch (SSNo) is usually performed with an arthroscopic procedure. This technique is well described but locating the nerve is complex because it is deeply buried and surrounded by soft tissue. We propose to combine ultrasound and arthroscopy (US-arthroscopy) to facilitate nerve localization, exposure and release. The main objective of this study was to assess the feasibility of this technique. This is an experimental, cadaveric study, carried out on ten shoulders. The first step of our technique is to locate the SSNo using an ultrasound scanner. Then an arthroscope is introduced under ultrasound control to the SSNo. A second portal is then created to dissect the pedicle and perform the ligament release. Ultrasound identification of the SSNo, endoscopic dissection and decompression of the nerve were achieved in 100% of cases. Ultrasound identification of the SSNo took an average of 3 min (± 4) while dissection and endoscopic release time took an average of 8 min (± 5). Ultrasound is an extremely powerful tool for non-invasive localization of nerves through soft tissues, but it is limited by the fact that tissue visualization is limited to the ultrasound slice plane, which is two-dimensional. On the other hand, arthroscopy (extra-articular) allows three-dimensional control of the surgical steps performed, but the locating of the nerve involves significant tissue detachment and a risk of damaging the nerve with the dissection. The combination of the two (US-arthroscopy) offers the possibility of combining the advantages of both techniques.

Abstract
This systematic review aimed to compare the analgesic effectiveness and complications rates for anterior suprascapular nerve blocks (ASSB) compared to interscalene brachial plexus blocks (ISB) for arthroscopic and outpatient shoulder surgery. Only randomized controlled trials (RCTs) comparing the ASSB versus ISB in the context of arthroscopic shoulder surgery were eligible for inclusion. The primary outcomes included pain scores (Numeric Rating Scale of 0 to 10) up to 24 h postoperatively and analgesic consumption. Secondary outcomes included block complications. Meta-analysis was performed using random-effects modeling and result certainty was determined using the GRADEpro tool. Six RCTs (709 patients) were included for analysis. ISB displayed a statistically significant reduction in pain scores by 0.40 (95%CI = 0.36 to 0.45; p < 0.00001) but not morphine equivalent consumption (mean difference = 0.74 mg; 95%CI = - 0.18 to 1.66 mg; I2 = 60%; p = 0.11; moderate certainty) immediately in the postoperative care unit. Opioid consumption and pain scores at 6 to 24 h were not significantly different. There was no difference in respiratory events postblock. ASSB demonstrated a significantly lower incidence of Horner's syndrome (relative risk (RR) = 0.17; 95%CI = 0.08 to 0.39; p < 0.00001; high certainty), voice hoarseness (RR = 0.24; 95%CI = 0.10 to 0.57; p < 0.00001; high certainty) and impaired respiratory function (p < 0.00001). The ASSB could be considered an appropriate analgesic option for arthroscopic shoulder surgery with potentially fewer complications than the ISB.

Abstract
Introduction Arthroscopic shoulder surgeries are usually performed in a sitting position. The sitting position is known to cause physiological changes related to cardiovascular adaptation. Interscalene nerve blocks (ISB) are the most commonly used techniques and are considered gold standard regional anesthesia methods for shoulder surgeries. Cerebral vessels located around sympathetic ganglia provide sympathetic system integrity. This local anesthetic spreading during ISB could be a side effect or provide a protective effect on cerebral ischemia. Our study aimed to investigate the cerebral protective effect of the ISB in arthroscopic shoulder surgeries in a sitting position. Material and methods After the approval of Koç University Clinical Research Ethics Committee (2020.020.IRB1.011), records of patients between January and December 2019 with shoulder arthroscopy at the Vehbi Koç Foundation (VKV) American hospital were retrospectively reviewed. Records of the hemodynamic response, INVOSTM (Medtronic, Minneapolis, USA) (rSO2) parameters, pain scores, and additional analgesic needs of all cases were examined in the intraoperative and postoperative period. Results Data of 40 patients who met the criteria to be included in the study was analyzed. Our study showed that the sitting position leading to hypotension coincided with a decrease in INVOS values. Nevertheless, we did not record any significant hypotension after ISB, and this may be due to the use of a minimal dose of local anesthetic. There was a certain increase in near-infrared spectroscopy (NIRS) values after ISB. We saw that the value of regional oxygen saturation (rSO2) increased on both the ISB side and the non-ISB side. This shows that the ISB can have a global impact on the brain. Specificially, the increase in rSO2 values in the ISB side compared to the other side suggests that ISB has possible positive effects on cerebral blood flow. Conclusion Our study has shown that ISB may transiently increase the rSO2 levels in the sitting position during shoulder surgery.

Abstract
Objectives The aim of this study was to evaluate the postoperative analgesia effect of ultrasound-guided single popliteal sciatic nerve block for calcaneal fracture. Methods A total of 120 patients scheduled for unilateral open reduction and internal fixation of calcaneal fracture were enrolled in this prospective randomized study. Patients in group B received ultrasound-guided single popliteal sciatic nerve block after operation, but Patients in group A did not. All patients received patient-controlled intravenous analgesia (PCIA) after operation. The time to initiation of PCIA, the time of first pressing the analgesia pump, duration of analgesia pump use and the total number of times the patient pressed the analgesia pump were recorded. The time of rescue analgesia and the adverse reactions were recorded. Pain magnitude of the patients immediately after discharge from operating room (T1), and at 4th (T2), 8th (T3), 12th (T4), 16th (T5), 24th (T6) and 48th (T7) h after the operation were assessed with visual analog scale (VAS). In addition, patient, surgeon and nurse satisfaction were recorded. Results The VAS scores at T2 ~ T5, the time of rescue analgesia and the adverse reactions, the total number of times the patient pressed the analgesia pump were significantly declined in group B (p < 0.001). The time to initiation of PCIA, the time of first pressing the analgesia pump, duration of analgesia pump use were prolonged and patient surgeon and nurse satisfaction were improved in group B (p < 0.05). Conclusion Ultrasound-guided single popliteal sciatic nerve block is an effective postoperative analgesia strategy for calcaneal fracture. Trial registration ChiCTR, ChiCTR2100042340.

Abstract
BACKGROUND Considering the adverse effects of opioids, it is essential to minimize their consumption for postoperative pain control. Studies have reported the opioid sparing effects of pregabalin, with conflicting results. Evidence for administering pregabalin in a multimodal regimen after arthroscopic rotator cuff repair surgery is limited. METHODS A total of 64 patients who underwent arthroscopic rotator cuff repair were enrolled in the cohort, and their data were retrospectively analyzed to evaluate the ability of pregabalin for postoperative analgesia and opioid sparing. The pregabalin group (n = 32) received additional pregabalin 75 mg for 2 weeks from the day before the surgery with the standard pain medications; in contrast, the control group (n = 32) was prescribed the standard pain medications alone. The total volume of patient-controlled anesthesia, doses of oral oxycodone and intravenous morphine as rescue analgesics, number of adverse events, and patient satisfaction based on the numeric rating scale (0-10) were assessed. Further, we used the visual analog scale for evaluating pain and function for 6 months in each group. RESULTS Total patient-controlled anesthesia volume, number of patient-controlled anesthesia attempts on the day of surgery, and total oral oxycodone consumption were significantly lower in the pregabalin group. Visual analog scale scores for pain and function showed no significant differences. Although the total number of adverse effects (nausea, vomiting, dizziness, dry mouth, urinary retention, itching sense, or constipation) was higher in the pregabalin group than in the control group, the difference was not statistically significant. CONCLUSION Our multimodal regimen with pregabalin significantly reduced opioid consumption with similar adverse effects. However, there was no significant difference in the pain score. We recommend pregabalin as an additional analgesic for arthroscopic rotator cuff repairs, especially for medium to large sized tears.

Suprascapular nerve block is a clinically attractive alternative to interscalene nerve block during arthroscopic shoulder surgery: a meta-analysis of randomized controlled trials. J Orthop Surg Res 2021; 16:376. [PMID: 34116689 PMCID: PMC8194158 DOI: 10.1186/s13018-021-02515-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Accepted: 06/02/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The interscalene brachial plexus block (ISB) is a commonly used nerve block technique for postoperative analgesia in patients undergoing shoulder arthroscopy surgery; however, it is associated with potentially serious complications. The use of suprascapular nerve block (SSNB) has been described as an alternative strategy with fewer reported side effects for shoulder arthroscopy. This review aimed to compare the impact of SSNB and ISB during shoulder arthroscopy surgery. METHODS A meta-analysis was conducted to identify relevant randomized controlled trials involving SSNB and ISB during shoulder arthroscopy surgery. Web of Science, PubMed, Embase, Cochrane Controlled Trials Register, Cochrane Library, Highwire, CNKI, and Wanfang database were searched from 2010 through March 2021. RESULTS We identified 1255 patients assessed in 17 randomized controlled trials. Compared with the ISB group, the SSNB group had higher VAS at rest in PACU (P = 0.003), 1 h after operation (P = 0.005), similar pain score 2 h (P = 0.39), 3-4 h (P = 0.32), 6-8 h after operation (P = 0.05), then lower VAS 12 h after operation (P = 0.00006), and again similar VAS 1 day (P = 0.62) and 2 days after operation (P = 0.70). As for the VAS with movement, the SSNB group had higher pain score in PACU (P = 0.03), similar VAS 4-6 h after operation (P = 0.25), then lower pain score 8-12 h after operation (P = 0.01) and again similar VAS 1 day after operation (P = 0.3) compared with the ISB group. No significant difference was found for oral morphine equivalents use at 24 h (P = 0.35), duration of PACU stay (P = 0.65), the rate of patient satisfaction (P = 0.14) as well as the rate of vomiting (P = 0.56), and local tenderness (P = 0.87). However, the SSNB group had lower rate of block-related complications such as Horner syndrome (P < 0.0001), numb (P = 0.002), dyspnea (P = 0.04), and hoarseness (P = 0.04). CONCLUSION Our high-level evidence established SSNB as an effective and safe analgesic technique and a clinically attractive alternative to interscalene block with the SSNB'S advantage of similar pain control, morphine use, and less nerve block-related complications during arthroscopic shoulder surgery, especially for severe chronic obstructive pulmonary disease, obstructive sleep apnea, and morbid obesity. Given our meta-analysis's relevant possible biases, we required more adequately powered and better-designed RCT studies with long-term follow-up to reach a firmer conclusion.

Abstract
Observational clinical research studies aim to assess which exposures (treatments or other factors; independent variable) affect patient outcomes (dependent variable). These exposures include medical interventions in situations where clinical trials are not possible or prior to their conduct and completion. However, the assessment of the relationship between exposures and outcomes is not straightforward, as other variables may need to be considered prior to reaching valid conclusions. Here, we present three hypothetical scenarios in regional anesthesia to review the epidemiological concepts of confounding, mediation, and effect modification. Understanding these concepts is critical for assessing the design, analysis, and interpretation of clinical studies. These terms may be confusing to anesthesiologists and researchers alike, where such confusion could affect the conclusions of a clinical study, mislead the target audience, and ultimately impact patient health.

Abstract
BACKGROUND Unilateral diaphragm paralysis (UDP) may potentially worsen sleep-disordered breathing (SDB). Unilateral diaphragm paralysis has been associated with proximal brachial plexus blockade, such as interscalene and supraclavicular block. The impact of UDP in patients with SDB is not known in this context. The objectives of this scoping review were to explore the associations between UDP and worsening SDB severity, oxygenation, and pulmonary function. METHODS A systematic search was developed, peer-reviewed, and applied to Embase, Medline, CINAHL, and Cochrane databases to include studies involving adult patients (≥ 18 yr) with SDB, where the effects of UDP on SDB severity, oxygenation, and pulmonary function were examined. RESULTS Six studies (n = 100 patients) with UDP and SDB were included. The sample population was derived exclusively from respirology-sleep clinics, and none were surgical patients. Compared with control (no UDP), UDP was associated with an increased respiratory disturbance index, most pronounced during rapid eye movement (REM) sleep and supine sleep. Supine and REM sleep were associated with obstructive and mixed (both obstructive and central) events, respectively. Compared with control, UDP was associated with a lower mean and minimum oxygen saturation and arterial oxygen tension during all sleep stages and in all body positions. The majority of UDP patients were found to have clinically significant reductions in mean forced expiratory volume in one second and forced vital capacity values, consistent with restrictive ventilatory pattern. CONCLUSION We observed an association between UDP and increasing SDB severity, particularly during REM sleep and while sleeping in the supine position. Although we identified weaknesses in study design and lack of perioperative data, anesthesiologists should be aware of this association when considering proximal brachial plexus blockade in patients with SDB.

Triple Monitoring May Avoid Intraneural Injection during Interscalene Brachial Plexus Block for Arthroscopic Shoulder Surgery: A Prospective Preliminary Study. J Clin Med 2021; 10:jcm10040781.

Abstract
Nerve injury is a feared complication of peripheral nerve blockade. The aim of this study was to test the effectiveness of a triple monitoring (TM), i.e., a combination of ultrasound (US), nerve stimulation (NS) and opening injection pressure (OIP) during interscalene brachial plexus block (IBPB) for surgery of the shoulder. Sixty patients undergoing IBPB for shoulder arthroscopy received TM. BSmart®, an inline injection device connected to a 10 mL syringe, was used to detect OIP during IBPB. Nerve stimulation was set to 0.5 mA to rule out any motor response, and if OIP was below 15 PSI, 10 mL of local anaesthetic was injected under US guidance between the C5 and C6 roots. The main outcome was the ability of TM to detect a needle–nerve contact. Other outcomes including the duration of IBPB; pain during injection; postoperative neurologic dysfunction. Triple monitoring revealed needle–nerve contact in 33 patients (55%). In 18 patients, NS evoked motor responses despite first control with US; in a further 15 patients, BSmart® detected an OIP higher than 15 PSI, despite the absence of motor response to NS. Mean duration of IBPB was 67.2 ± 5.3 seconds; neither pain during injection nor postoperative neurologic dysfunctions were detected. Clinical follow up excluded the presence of postoperative neuropathies. Triple monitoring showed to be a useful and feasible tool while performing IBPB for arthroscopic shoulder surgery. Future studies will be needed to confirm our findings.

Abstract
PURPOSE To report clinical outcomes following arthroscopic suprascapular nerve (SSN) decompression for suprascapular neuropathy at the suprascapular and/or spinoglenoid notch in the absence of major concomitant pathology. METHODS We retrospectively reviewed prospectively collected data of 19 patients who underwent SSN release at the suprascapular and/or spinoglenoid notch between April 2006 and August 2017 with ≥2 years of follow-up. Patients who underwent concomitant rotator cuff or labral repairs or had severe osteoarthritis were excluded. Pre- and postoperative strength and patient-reported outcomes were collected, including the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numerical Evaluation (SANE), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), 12-item Short Form (SF-12), and satisfaction. Complications and revisions were recorded. RESULTS At a mean final follow-up of 4.8 years, pre- to postoperative ASES (64.9 ± 18.7 versus 83.5 ± 23.1; P = .018), QuickDASH (28.7 ± 17.2 versus 12.7 ± 17.1; P = .028), SANE (64.3 ± 16.4 versus 80.8 ± 22.3; P = .034), and SF-12 PCS (41.1 ± 10.8 versus 52.3 ± 5.8; P = .007) scores all significantly improved. Median strength for external rotation improved significantly (4 [range 2 to 5] versus 5 [range 3 to 5]; P = .014). There was no statistically significant improvement in median strength for abduction (4 [range 3 to 5] versus 5 [5]; P = .059). Median postoperative satisfaction was 9 (range 1 to 10), with 8 patients (50%) rating satisfaction ≥9. No complications were observed, and no patients went on to revision surgery. CONCLUSION Arthroscopic SSN decompression for suprascapular neuropathy at the suprascapular and/or spinoglenoid notch in the absence of major concomitant glenohumeral pathology results in good functional outcomes with significant improvements from before to after surgery. LEVEL OF EVIDENCE IV, therapeutic case series.

Abstract
BACKGROUND Spinal morphine is the mainstay of postcesarean analgesia. Quadratus lumborum block has recently been proposed as an adjunct or alternative to spinal morphine. The authors evaluated the analgesic effectiveness of quadratus lumborum block in cesarean delivery with and without spinal morphine. METHODS Randomized trials evaluating quadratus lumborum block benefits in elective cesarean delivery under spinal anesthesia were sought. Three comparisons were considered: spinal morphine versus spinal morphine and quadratus lumborum block; spinal morphine versus quadratus lumborum block; and no block or spinal morphine versus quadratus lumborum block. The two coprimary outcomes were postoperative (1) 24-h cumulative oral morphine equivalent consumption and (2) pain at 4 to 6 h. Secondary outcomes included area under the curve pain, time to analgesic request, block complications, and opioid-related side effects. RESULTS Twelve trials (924 patients) were analyzed. The mean differences (95% CIs) in 24-h morphine consumption and pain at 4 to 6 h for spinal morphine versus spinal morphine and quadratus lumborum block comparison were 0 mg (-2 to 1) and -0.1 cm (-0.7 to 0.4), respectively, indicating no benefit. For spinal morphine versus quadratus lumborum block, these differences were 7 mg (-2 to 15) and 0.6 cm (-0.7 to 1.8), respectively, also indicating no benefit. In contrast, for no block or spinal morphine versus quadratus lumborum block, improvements of -18 mg (-28 to -7) and -1.5 cm (-2.4 to -0.6) were observed, respectively, with quadratus lumborum block. Finally, for no block or spinal morphine versus quadratus lumborum block, quadratus lumborum block improved area under the 48-h pain curve by -4.4 cm · h (-5.0 to -3.8), exceeding the clinically important threshold (3.96 cm · h), but no differences were observed in the other comparisons. CONCLUSIONS Moderate quality evidence suggests that quadratus lumborum block does not enhance analgesic outcomes when combined with or compared with spinal morphine. However, the block improves postcesarean analgesia in the absence of spinal morphine. The clinical utility of this block seems limited to situations in which spinal morphine is not used.

Abstract
The choice of anaesthetic in shoulder surgery is an evolving field of research which has important implications for patient outcomes. We have performed a prospective study to assess the usability of an interscalene brachial plexus block (ISBPB) with sedation as the primary anaesthetic and analgesic for arthroscopic shoulder surgery. Our study assessed the requirements of analgesia peri-operatively and post operatively and found that patients had no requirement (n = 30) and minimal requirements with a low pain score (visual analogue score; mean 2.4, range 2-5) respectively. We also found that patients spent a short amount of time in recovery (31 min mean, range 21-48 min) and were able to be discharged on the same day. Our findings suggest that ISBPB with sedation is a viable option in arthroscopic shoulder surgery for a variety of procedures with positive effects for patient outcomes and mobility.

Abstract
BACKGROUND The use of opioid analgesia is common in both the acute and extended post-operative periods after rotator cuff repair. The current opioid crisis has prompted surgeons to seek alternatives that minimize or even eliminate the need for oral opioids after surgery. QUESTIONS/PURPOSES We sought to investigate the effects on post-operative opioid use of a surgeon-administered block of the suprascapular and axillary nerves in arthroscopic rotator cuff repair (ARCR), in particular to quantify outpatient opioid consumption and duration. METHODS In this prospective observational study, all patients undergoing primary ARCR performed under general anesthesia by a single surgeon were studied over a 15-month period. Of 91 ARCRs performed, 87 patients were enrolled and followed prospectively. At the conclusion of the procedure, the surgeon performed "local-regional" nerve blockade with injections to the sensory branches of the suprascapular nerve and the axillary nerve, as well as local infiltration about the shoulder. Use of medications in the post-anesthesia care unit was left up to the anesthesiologist. Patients were prescribed oral opioids (hydrocodone/acetaminophen 5/325 mg) for analgesia after discharge. The quantity and duration of opioid use and pain scores were recorded for 4 months. Statistical analysis was performed to evaluate factors that could account for greater opioid use. RESULTS Total opioid consumption ranged from 0 to 30 opioid tablets (average, 4.2 tablets) over the 4-month period. Post-operatively, 91% of patients took between ten or fewer tablets, and 39% took no opioids. The average duration of opioid use was 2.4 days. No patients were taking opioids at the 4- to 6-week or 4-month follow-up visits, none required refills, and none received prescriptions from outside prescribers. No statistically significant differences were seen in opioids taken or duration of use in regard to tear size, sex, body mass index, surgery location, or procedure time. There was a significant inverse correlation between opioid use and age. In addition, the cost of the surgeon-performed procedure was substantially lower than that associated with pre-operative nerve blockade performed by an anesthesiologist. All patients were satisfied with the post-operative pain management protocol. Average reported post-operative pain scores were low and decreased at each visit. CONCLUSION With this local-regional nerve-blocking protocol, opioid use after ARCR was unexpectedly low, and a large proportion of patients recovered without any post-surgical opioids. The correlation seen between opioid use and age may not be clinically significant, given the low use of post-operative opioids overall. These results may be useful in guiding post-operative opioid prescribing after ARCR, as well as in lowering costs associated with ARCR.
