Background and objectives: Preoperative anxiety is an enormous feeling of fear that is seen in all patients undergoing surgery. The severity of anxiety may vary depending on the type of surgery and anesthesia to be performed. The aim of this study is to compare the effects of brachial plexus blocks and general anesthesia methods on preoperative anxiety levels in patients who will undergo orthopedic upper-extremity surgery and to determine the factors affecting anxiety. Materials and Methods: After randomization, the Amsterdam Preoperative Anxiety and Knowledge Scale (APAIS) questionnaire was applied to the patients to determine the preoperative anxiety level, and then anesthesia was applied according to the anesthesia type determined. Pain scores (1, 8, 16, and 24 h) and total opioid consumption of the patients were recorded postoperatively. Results: The APAIS score of the patients in the general anesthesia (GA) group was significantly higher (p = 0.021). VAS score medians at 1, 4, and 8 h postoperatively were found to be significantly higher in the GA group (p < 0.001, p < 0.001 and p = 0.044, respectively). Conclusions: USG-guided BPB may cause less anxiety than GA in patients who will undergo elective upper-extremity surgery. However, these patients have moderate anxiety, although it is more associated with advanced age, female gender, and education level.

The optimal surgical excision margins are uncertain for patients with thick (>2 mm) localised cutaneous melanomas. In our previous report of this multicentre, randomised controlled trial, with a median follow-up of 6·7 years, we showed that a narrow excision margin (2 cm vs 4 cm) did not affect melanoma-specific nor overall survival. Here, we present extended follow-up of this cohort. In this open-label, multicentre randomised controlled trial, we recruited patients from 53 hospitals in Sweden, Denmark, Estonia, and Norway. We enrolled clinically staged patients aged 75 years or younger diagnosed with localised cutaneous melanoma thicker than 2 mm, and with primary site on the trunk or upper or lower extremities. Patients were randomly allocated (1:1) to treatment either with a 2-cm or a 4-cm excision margin. A physician enrolled the patients after histological confirmation of a cutaneous melanoma thicker than 2 mm. Some patients were enrolled by a physician acting as responsible for clinical care and as a trial investigator (follow-up, data collection, and manuscript writing). In other cases physicians not involved in running the trial enrolled patients. Randomisation was done by telephone call to a randomisation office, by sealed envelope, or by computer generated lists using permuted blocks. Patients were stratified according to geographical region. No part of the trial was masked. The primary outcome in this extended follow-up study was overall survival and the co-primary outcome was melanoma-specific survival. All analyses were done on an intention-to-treat basis. The study is registered with ClinicalTrials.gov, number NCT03638492. Between Jan 22, 1992, and May 19, 2004, 936 clinically staged patients were recruited and randomly assigned to a 4-cm excision margin (n=465) or a 2-cm excision margin (n=471). At a median overall follow-up of 19·6 years (235 months, IQR 200–260), 621 deaths were reported—304 (49%) in the 2-cm group and 317 (51%) in the 4-cm group (unadjusted HR 0·98, 95% CI 0·83–1·14; p=0·75). 397 deaths were attributed to cutaneous melanoma—192 (48%) in the 2-cm excision margin group and 205 (52%) in the 4-cm excision margin group (unadjusted HR 0·95, 95% CI 0·78–1·16, p=0·61). A 2-cm excision margin was safe for patients with thick (>2 mm) localised cutaneous melanoma at a follow-up of median 19·6 years. These findings support the use of 2-cm excision margins in current clinical practice.

Stroke is the principal cause of permanent disability in adult age, and many patients require lifelong medical treatment and care from others for their daily activities. It has enormous repercussions on the work and social lives of patients and their families and involves major economic expenditure. Post-stroke spastic upper limb is usually treated with rehabilitation, occupational therapy, and periodical injections of botulinum toxin, while surgical correction is now seldom considered. However, there has been no clinical trial to compare between surgical and toxin treatments. The primary aim of this study is to compare outcomes between surgery and a conventional approach with botulinum toxin in patients with post-stroke upper limb spasticity. A two-arm (surgical treatment [n = 22] vs. botulinum toxin [n = 22]) randomized clinical trial (RCT) will be performed to compare the efficacy of surgery with that of botulinum toxin treatment in patients with post-stroke upper limb spasticity. Data will be collected at baseline and at 6 and 12 months of follow-up on functionality, hygienic status, quality of life, sleep quality, anxiety/depression levels, and functional magnetic resonance imaging (fMRI)-measured brain activity. Healthcare and care costs will be compared between the groups. This research is set in the context of chronic diseases, aging, and functional/mobility limitations. The results can be expected to have a major impact, because the high prevalence of stroke and the severe associated disability means that an enormous number of patients can benefit from improved treatment protocols, and a more rational use of resources would yield considerable economic benefits for health and care systems. Our expectation is that outcomes would be more favorable with surgery. However, the aim is not to exclude any approach but rather to explore how the potential and indications of each treatment could be integrated within a multidisciplinary therapeutic protocol in a complementary manner.

ObjectiveInvestigate the effect of passive, active or no intra-operative work breaks on static, median and peak muscular activity, muscular fatigue, upper body postures, heart rate, and heart rate variability. BackgroundAlthough laparoscopic surgery is preferred over open surgery for the benefit of the patient, it puts the surgeons at higher risk for developing musculoskeletal disorders especially due to the less dynamic and awkward working posture. The organizational intervention intraoperative work break is a workplace strategy that has previously demonstrated positive effects in small-scale intervention studies. MethodsTwenty-one surgeons were exposed to three 90-min conditions: no breaks, 2.5-min passive (standing rest) or active (targeted stretching and mobilization exercises) breaks after 30-min work blocks. Muscular activity and fatigue of back, shoulder and forearm muscles were assessed by surface electromyography; upper body posture, i.e., spinal curvature, by inclination sensors; and heart rate and variability (HRV) by electrocardiography. Generalized estimating equations were used for statistical analyses. This study (NCT03715816) was conducted from March 2019 to October 2020.ResultsThe HRV-metric SDNN tended to be higher, but not statistically significantly, in the intervention conditions compared to the control condition. No statistically significant effects of both interventions were detected for muscular activity, joint angles or heart rate.ConclusionIntraoperative work breaks, whether passive or active, may counteract shoulder muscular fatigue and increase heart rate variability. This tendency may play a role in a reduced risk for developing work-related musculoskeletal disorders and acute physical stress responses.

Background Tourniquets are widely used in limb fracture surgeries. Controversies still exist about the pressure inflated, including unified tourniquet inflation pressure (UTIP) and personalized tourniquet inflation pressure (PTIP). This study evaluated the hemostatic effect between UTIP and PTIP based on systolic blood pressure (SBP) in extremity fracture patients. Materials and methods Patients with fresh extremity fractures requiring tourniquets during surgeries were prospectively enrolled and randomly assigned to the UTIP and PTIP groups. The inflation pressure was set to 250 mmHg for the upper extremities and 300 mmHg for the lower extremities in the UTIP group and SBP plus 50 mmHg for the upper extremities and SBP plus 100 mmHg for the lower extremities in the PTIP group. The primary outcome was a hemostatic effect evaluated by the surgeon (satisfied or dissatisfied). Other secondary outcomes included postoperative changes in limb swelling and tourniquet-related complications. Results A total of 144 patients were enrolled and randomly assigned to the UTIP group or the PTIP group, and each group has 72 patients (36 upper limb and 36 lower limb). Totally, the hemostasis effect of the PTIP group was worse than that of the UTIP group by non-inferiority test. The hemostatic effect of upper limb fractures with SBP plus 50 mmHg for tourniquet inflation pressure was also worse than that with 250mmHg; however, there was no statistically significant difference between 300mmHg and SBP plus 100 mmHg in the lower limb group hemostasis effect due to a lack of power. Also, no difference was observed in the incidence of complications ( p  = 1.000) and postoperative changes in limb swelling during 2 days after surgery (upper limb: P1 = 0.546, P2 = 0.545; lower limb: P1 = 0.408, P2 = 0.857) between the PTIP and UTIP group. Conclusion In the surgery of limb fractures, setting SBP + 50mmHg as tourniquet pressure may not be sufficient for upper limbs. Also, we found no difference between the SBP + 100mmHg and the unified 300mmHg for lower limb surgeries.

Distal radius fractures (DRFs) are common injuries among older adults and can result in substantial disability. Current evidence regarding long-term outcomes in older adults is scarce. To compare outcomes across treatment groups at 24 months among adults with DRFs who participated in the WRIST trial. The Wrist and Radius Injury Surgical Trial (WRIST) randomized, international, multicenter trial was conducted from April 1, 2012, through December 31, 2016. Participants were adults aged 60 years or older with isolated, unstable DRFs at 24 health systems in the US, Canada, and Singapore. Data analysis was performed from March 2019 to March 2021. Participants were randomized to open reduction and volar locking plate system (VLPS), external fixation with or without supplementary pinning (EFP), and percutaneous pinning (CRPP). The remaining participants chose closed reduction and casting. The primary outcome was the 24-month Michigan Hand Outcomes Questionnaire (MHQ) summary score. Secondary outcomes were scores on the MHQ subdomains hand strength and wrist motion. A total of 304 adults were recruited for the study, and 187 were randomized to undergo surgery, 65 to VLPS, 64 to EFP, and 58 to CRPP; 117 participants opted for closed reduction and casting. Assessments were completed at 24 months for 182 participants (160 women [87.9%]; mean [SD] age, 70.1 [8.5] years). Mean MHQ summary scores at 24 months were 88 (95% CI, 83-92) for VLPS, 83 (95% CI, 78-88) for EFP, 85 (95% CI, 79-90) for CRPP, and 85 (95% CI, 79-90) for casting, with no clinically meaningful difference across groups after adjusting for covariates (χ23 = 1.44; P = .70). Pain scores also did not differ across groups at 24 months (χ23 = 2.64; P = .45). MHQ summary scores changed from 82 (95% CI, 80-85) to 85 (95% CI, 83-88) (P = .12) between 12 and 24 months across groups. The rate of malunion was higher in the casting group (26 participants [59.1%]) than in the other groups (4 participants [8.0%] for VLPS, 8 participants [17.0%] for EFP, and 4 participants [9.8%] for CRPP; χ23 = 43.6; P < .001), but malunion was not associated with the 24-month outcome difference across groups. The study did not find clinically meaningful patient-reported outcome differences 24 months after injury across treatment groups, with little change between 12 and 24 months. These findings suggest that long-term outcomes need not necessarily be considered in deciding between treatment options. Patient needs and recovery goals that fit to relative risks and benefits of each treatment type will be more valuable in treatment decision-making. ClinicalTrials.gov Identifier: NCT01589692.

Background: Breast cancer stands out among the most widely recognized forms of cancer among women. It has been observed that upper extremity lymphedema is one of the most risky and prevalent complication following breast cancer surgery that prompts functional impairment, psychological, and social problems. Purpose: To compare the effects of Kinesio taping and the application of the pressure garment on secondary lymphedema of the upper extremity. Methods: 66 women were randomly allocated to the Kinesio taping (KT) group (n=33) and pressure garment (PG) group (n=33). The KT group received Kinesio taping application (2 times per week for 3 weeks), while the PG group received pressure garment (20- 60 mmHg) for at least 15-18 hours per day for 3 weeks. The outcome measures were limb circumference, Shoulder Pain and Disability Index questionnaire (SPADI), hand grip strength, and quality of life at the baseline and end of intervention. Results: The sum of limb circumferences, SPADI, hand grip strength, and quality of life significantly improved after treatment in the KT group (P<0.05). While the PG group showed no significant improvement in SPADI, hand grip strength, physical, role, pain, and fatigue score p>0.05, while the sum of limb circumferences significantly decreased (P<0.05). Significant differences were observed between the KT and PG groups at the end of the intervention (P<0.05). Conclusion: KT had significant changes in limb circumference, SPADI, hand grip strength and overall quality of life than PG in the treatment of subjects diagnosed with lymphedema after mastectomy.

Background This two-centre randomized trial compared costoclavicular and paracoracoid ultrasound-guided infraclavicular brachial plexus block in patients undergoing upper limb surgery. We hypothesized that both techniques would result in similar onset times and designed the study as an equivalence trial. Methods Ninety patients undergoing upper limb surgery at or distal to the elbow were randomly allocated to receive a costoclavicular ( n = 45) or paracoracoid ( n = 45) ultrasound-guided infraclavicular brachial plexus block. Both groups received a 35-mL mixture of 1% lidocaine–0.25% bupivacaine with epinephrine 5 µg·mL −1 . In the costoclavicular group, local anesthetic was injected into the costoclavicular space in the middle of the three cords of the brachial plexus. In the paracoracoid group, local anesthetic was deposited dorsal to the axillary artery in the lateral infraclavicular fossa. A blinded observer recorded the block onset time (primary endpoint), success rate (i.e., surgical anesthesia), block-related pain scores, as well as the incidence of hemidiaphragmatic paralysis. Performance time and the number of needle passes were also recorded during the performance of the block. The total anesthesia-related time was defined as the sum of the performance and onset times. Results The mean (SD) onset times were comparable between the costoclavicular and paracoracoid groups [16.0 (7.5) min vs 16.8 (6.2) min, respectively; mean difference, 0.8; 95% confidence interval, -2.3 to 3.8; P = 0.61]. Furthermore, no intergroup differences were found in terms of performance time ( P = 0.09), total anesthesia-related time ( P = 0.90), surgical anesthesia ( P  > 0.99), and hemidiaphragmatic paralysis ( P > 0.99). The paracoracoid technique required marginally fewer median [interquartile range] needle passes than the costoclavicular technique (2 [1-4] vs 2 [1-6], respectively; P = 0.048); however, procedural pain was comparable between the two study groups. Conclusion Costoclavicular and paracoracoid ultrasound-guided infraclavicular blocks resulted in similar onset times. Furthermore, no intergroup differences were found in terms of performance times and success rates. Future dose-finding trials are required to elucidate the minimum effective volume of local anesthetic for costoclavicular infraclavicular blocks.

IntroductionCancer-related lymphoedema is one of the most debilitating side-effects of cancer treatment with an overall incidence of 15.5%. Patients may suffer from a variety of symptoms, possibly resulting in a diminished health-related quality of life (HRQoL). A microsurgical technique known as lymphaticovenous anastomosis (LVA) might be a promising treatment option. The objective of this study is to evaluate whether LVA is effective and cost-effective compared with sham surgery in improving the HRQoL.Methods and analysisA multicentre, double-blind, randomised sham-controlled trial conducted in three university hospitals in the Netherlands. The study population comprises 110 patients over the age of 18 years with unilateral, peripheral cancer-related lymphoedema, including 70 patients with upper limb lymphoedema and 40 patients with lower limb lymphoedema. A total of 55 patients will undergo the LVA operation, while the remaining 55 will undergo sham surgery. The follow-up will be at least 24 months. Patients are encouraged to complete the follow-up by explaining the importance of the study. Furthermore, patients may benefit from regular monitoring moments for their lymphoedema. The primary outcome is the HRQoL. The secondary outcomes are the limb circumference, excess limb volume, changes in conservative therapy, postoperative complications, patency of the LVA and incremental cost-effectiveness.Ethics and disseminationThe study was approved by the Medical Ethical Committee of Maastricht University Medical Center on 20 September 2023 (NL84169.068.23). The results will be presented at scientific conferences and published in peer-reviewed medical journals.Trial registration numberNCT06082349.

Background and ObjectivesThe comparative incidences of hemidiaphragmatic paralysis associated with contemporary ultrasound-guided supraclavicular versus infraclavicular blockade have not received extensive study. We tested the hypothesis that the infraclavicular approach results in a lower incidence of hemidiaphragmatic paralysis compared with supraclavicular blockade when a standard local anesthetic volume and concentration are used.MethodsWith institutional human ethics board approval, we enrolled 64 patients undergoing right-sided upper extremity surgery in a randomized, blinded, parallel-group trial. Patients were assigned to ultrasound-guided supraclavicular or infraclavicular blockade with 30 mL of 0.5% ropivacaine. The primary end point was complete hemidiaphragmatic paralysis at 30 minutes, defined as a greater than 75% reduction in diaphragmatic excursion measured with the voluntary sniff test using M-mode ultrasonography. Partial paralysis was defined as a 25% to 75% reduction.ResultsEleven (34%) of 32 patients in the supraclavicular group versus 1 (3%) of 32 in the infraclavicular group had complete hemidiaphragmatic paralysis (P = 0.001 [1-tailed]; relative risk, 11.0 [95% confidence interval, 1.5–80.3]); 44% versus 13% had any (complete or partial) paralysis (P = 0.006; relative risk, 3.5 [95% confidence interval, 1.3–9.5]). Eight (25%) of 32 patients in the supraclavicular group versus 5 (16%) of 32 in the infraclavicular group reported dyspnea (P = 0.54).ConclusionsUltrasound-guided supraclavicular blockade with 30 mL of 0.5% ropivacaine produced complete hemidiaphragmatic paralysis in approximately one-third of patients. The infraclavicular approach greatly reduced this risk but did not eliminate it. These data may aid in the selection of the approach to brachial plexus blockade, particularly in ambulatory patients and/or those with respiratory comorbidities.
