SUMMARY: The application effect of transversus abdominis plane block (TAPB) combined with thoracic paravertebral block (TPVB) or erector spinae plane block (ESP) under ultrasound guidance in endoscopic radical resection of esophageal cancer under general anesthesia was studied. From March 2021 to February 2022, patients who underwent endoscopic radical resection of esophageal cancer in our hospital were selected as the research object, and 90 patients were selected as the samples. Patients were divided into groupA and group B according to the difference of blocking schemes. Group A received ESP and Group B received TPVB. The dosage of sufentanil, nerve block time, awakening time and extubation time of the two groups were counted. The postoperative pain, sedation effect, sleep satisfaction and analgesia satisfaction of the two groups were compared, and the complications of the two groups were observed. The nerve block time and extubation time in group A were shorter than those in group B (P0.05). At T2, T3 and T4, the visual analogue scale (VAS) scores of group A at rest and cough were significantly lower than those of group B (P0.05). The satisfaction of sleep and analgesia in group A was higher than that in group B (P0.05). The analgesic effect of ultrasound-guided TAPB combined with ESP is better than that of ultrasound-guided TAPB combined with TPVB, and it can shorten the time of nerve block and extubation, which is worth popularizing.
Se estudió el efecto de la aplicación del bloqueo del plano transverso del abdomen (TAPB) combinado con el bloqueo paravertebral torácico (TPVB) o el bloqueo del plano del erector de la columna (ESP) bajo guía ecográfica en la resección radical endoscópica del cáncer de esófago bajo anestesia general. Desde marzo de 2021 hasta febrero de 2022, en nuestro hospital, se seleccionaron como objeto de investigación pacientes sometidos a resección radical endoscópica de cáncer de esófago, y como muestra se seleccionaron 90 pacientes. Los pacientes se dividieron en el grupo A y el grupo B según la diferencia de esquemas de bloqueo. El grupo A recibió ESP y el grupo B recibió TPVB. Se contaron la dosis de sufentanilo, el tiempo de bloqueo nervioso, el tiempo de despertar y el tiempo de extubación de los dos grupos. Se compararon el dolor posoperatorio, el efecto de la sedación, la satisfacción del sueño y la satisfacción de la analgesia de los dos grupos y se observaron las complicaciones de los dos grupos. El tiempo de bloqueo nervioso y el tiempo de extubación en el grupo A fueron más cortos que los del grupo B (P0,05). En T2, T3 y T4, las puntuaciones de la escala visual analógica (EVA) del grupo A en repo- so y tos fueron significativamente más bajas que las del grupo B (P 0,05). La satisfacción del sueño y la analgesia en el grupo A fue mayor que en el grupo B (P0,05). El efecto analgésico de la TAPB guiada por ecografía combinada con ESP es mejor que el de la TAPB guiada por ecografía combinada con TPVB, y puede acortar el tiempo de bloqueo nervioso y extubación, lo que vale la pena popularizar.

Abstract Background: Neonatal lupus (NL) is extremely rare and is caused by the transplacental passage of maternal IgG autoantibodies against Ro, La, and/or RNP proteins into the fetal circulation, which can cause congenital complete atrioventricular block (CCAB), permanent skin lesions, and liver involvement. Objective: To know the prevalence of NL in patients with CCAB and the clinical course in long-term follow-up. Methods: From January 1992 to December 2017, patients with CCAB were included. The presence of anti-SSA/Ro and anti-SSB/La antinuclear antibodies in maternal serum confirmed NL. Results: Eight patients were included with a follow-up of 10 ± 6 years; NL was concluded in 62.5%; two were male. One of them was diagnosed in utero, two at birth, and a pacemaker was implanted in them, one at 12 years of age and another at 15. The other two cases were diagnosed at 18 and 26 years of age, and permanent pacemakers were implanted 8 and 5 years later, respectively. In one case, a definitive pacemaker was not implanted in a newborn with only 1 year of follow-up. At delivery, 60% of the mothers were free of rheumatic disease, and altogether, they all had 19 children; none of them presented NL manifestations. Conclusions: CCAB is rare and frequently associated with a maternal autoimmune disease, practically all of them will require a definitive pacemaker at some point in their lives.
Resumen Antecedentes: El lupus neonatal (LN) es extremadamente raro y es ocasionado por el paso transplacentario de auto-anticuerpos maternos IgG contra las proteínas Ro, La y/o RNP a la circulación fetal que puede ocasionar bloqueo aurículo-ventricular completo congénito (BAVCC) permanente, lesiones dérmicas y afectación hepática. Objetivo: Conocer la prevalencia de LN en paciente con BAVCC y la evolución clínica en un seguimiento a largo plazo. Métodos: De enero de 1992 a diciembre 2017 se incluyeron paciente con BAVCC. La presencia de anticuerpos antinucleares anti-SSA/Ro y anti-SSB/La en suero materno confirmó LN. Resultados: Ocho pacientes fueron incluidos con seguimiento de 10 ± 6 años, el 62.5 % con LN; dos fueron del sexo masculino. Uno diagnosticado in útero, dos al nacimiento, en ellos se implantó marcapaso; uno a los 12 años de edad y otro a los 15. Los otros dos casos fueron diagnosticados a los 18 y 26 años, se implantó marcapaso definitivo en ellos 8 y 5 años después respectivamente. En un caso no se implantó marcapaso definitivo; un recién nacido con solo un año de seguimiento. Al dar a luz, el 60 % de las madres estaban libres de enfermedad reumática y en conjunto todas tuvieron 19 hijos, ninguno de ellos presentó manifestaciones de LN. Conclusiones: El BAVCC es raro y frecuentemente está asociado a una enfermedad autoinmune materna, prácticamente todos requerirán de marcapaso definitivo en alguna época de su vida.

Resumo Fundamento: O prolongamento do intervalo PQ, geralmente associado a um atraso na condução atrioventricular, pode estar relacionado a alterações na propagação do impulso intraventricular. Objetivo: Avaliar, por meio do mapeamento do potencial de superfície corporal (BSPM), o processo de despolarização ventricular em atletas com intervalos PQ prolongados em repouso e após o exercício. Métodos: O estudo incluiu 7 esquiadores cross-country com intervalo PQ superior a 200 ms (grupo PQ Prolongado) e 7 com intervalo PQ inferior a 200 ms (grupo PQ Normal). O BSPM de 64 derivações unipolares do tronco foi realizado antes (Pré-Ex) e após o teste ergométrico de bicicleta (Pós-Ex). Mapas equipotenciais da superfície corporal foram analisados durante a despolarização ventricular. O nível de significância foi de 5%. Resultados: Comparado com atletas com PQ Normal, o primeiro e o segundo períodos de posição estável dos potenciais cardíacos na superfície do tronco foram mais longos, e a formação da distribuição de potencial "sela" ocorreu mais tarde, no Pré-Ex, nos atletas com PQ Prolongado. No Pós-Ex, o grupo PQ Prolongado apresentou um encurtamento do primeiro e segundo períodos de distribuições de potencial estáveis e uma diminuição no tempo de aparecimento do fenômeno "sela" em relação ao Pré-Ex (para valores próximos aos do Normal -Grupo PQ). Além disso, no Pós-Ex, a primeira inversão das distribuições de potencial e a duração total da despolarização ventricular em atletas com PQ Prolongado diminuíram em comparação com o Pré-Ex e com valores semelhantes em atletas com PQ Normal. Em comparação com atletas com PQ Normal, a segunda inversão foi mais longa no Pré-Ex e Pós-Ex em atletas com PQ Prolongado. Conclusão: Atletas com PQ prolongado apresentaram diferenças significativas nas características temporais do BSPM durante a despolarização ventricular, tanto em repouso quanto após o exercício, em comparação com atletas com PQ normal.
Abstract Background: Prolongation of the PQ interval, generally associated with an atrioventricular conduction delay, may be related to changes in intraventricular impulse spreading. Objective: To assess, using body surface potential mapping (BSPM), the process of ventricular depolarization in athletes with prolonged PQ intervals at rest and after exercise. Methods: The study included 7 cross-country skiers with a PQ interval of more than 200 ms (Prolonged-PQ group) and 7 with a PQ interval of less than 200 ms (Normal-PQ group). The BSPM from 64 unipolar torso leads was performed before (Pre-Ex) and after the bicycle exercise test (Post-Ex). Body surface equipotential maps were analyzed during ventricular depolarization. The significance level was 5%. Results: Compared to Normal-PQ athletes, the first and second periods of the stable position of cardiac potentials on the torso surface were longer, and the formation of the "saddle" potential distribution occurred later, at Pre-Ex, in Prolonged-PQ athletes. At Post-Ex, the Prolonged-PQ group showed a shortening of the first and second periods of stable potential distributions and a decrease in appearance time of the "saddle" phenomenon relative to Pre-Ex (to the values near to those of the Normal-PQ group). Additionally, at Post-Ex, the first inversion of potential distributions and the total duration of ventricular depolarization in Prolonged-PQ athletes decreased compared to Pre-Ex and with similar values in Normal-PQ athletes. Compared to Normal-PQ athletes, the second inversion was longer at Pre-Ex and Post-Ex in Prolonged-PQ athletes. Conclusion: Prolonged-PQ athletes had significant differences in the temporal characteristics of BSPM during ventricular depolarization both at rest and after exercise as compared to Normal-PQ athletes.

Objective To analyze the micronucleus rate of radiation workers and to provide accurate occupational health monitoring basis in radiation workers exposed to low-level ionizing radiation for a long time. Methods The radiation group consisted of 353 radiation workers who had been exposed to ionizing radiation during work, while the control group consisted of 41 radiation workers who had not yet been exposed to ionizing radiation before work. The cytokinesis-block micronucleus method was used to determine the micronucleus rate. Results The average micronucleus rate in the radiation group was significantly higher than that in the control group (t = −2.95, P < 0.05). In the radiation group, the micronucleus rate gradually increased with age, and the difference was statistically significant (F = 8.36, P < 0.05). The micronucleus rates of workers with > 10 and > 30 years of service were significantly higher than those of workers with < 10 years of service (χ2 = −44.79, −60.47, P < 0.05). The micronucleus rate in females was significantly higher than that in males (t = 3.93, P < 0.05). The micronucleus rates in the diagnostic radiology group and the industrial detection group were significantly higher than that in the control group (t = 3.51, 3.65, P < 0.05). Conclusion The micronucleus rate has increased among the radiation workers exposed to low-level ionizing radiation for a long time. It is necessary to further strengthen occupational health monitoring and radiation protection education for radiation workers, especially the medical workers that constitute the largest population of radiation exposure workers.

Objective To investigate the short-term efficacy of celiac plexus block combined with the interstitial permanent implantation of 125I seeds in the treatment of advanced pancreatic cancer (inoperable locally advanced and metastatic pancreatic cancers). Methods A total of 100 patients with advanced pancreatic cancer were selected and treated with celiac plexus block combined with the interstitial permanent implantation of 125I seeds under CT guidance. Pain relief and changes in the tumor marker CA19-9 were assessed on the seventh day, the first and third months after surgery. In the third month after surgery, tumor size was assessed by CT. Results Among the 100 patients with advanced pancreatic cancer, complete response (CR) was found in 12 cases, partial response (PR) in 78 cases, stable disease in five cases, and progression of disease in five cases three months after surgery. The CA19-9 level and the sum of short and long tumor diameters were significantly decreased (both P<0.01). A total of 100 patients had severe pain before treatment (visual analogue scale (VAS)): 7–10 points), 59 patients reported pain disappearance (VAS: 0 points), 35 patients had mild pain (VAS: 1–3 points), and six patients experienced moderate pain (VAS: 4–6 points) in the third month after treatment. The pain relief rate was 100%. Conclusion Celiac plexus block combined with the interstitial permanent implantation of 125I seeds has good short-term efficacy and can effectively improve short-term pain in patients with advanced pancreatic cancer.

ObjectiveTo explore the efficacy and predictive indicators of stellate ganglion block （SGB） as an adjunctive intervention for chronic subjective tinnitus and accumulate experience for the application of SGB in the clinical treatment of tinnitus. MethodsA retrospective review was conducted on the data of chronic subjective tinnitus patients who received SGB intervention， with unsatisfactory outcomes otherwise. Pure tone audiometry （PTA）， tinnitus loudness evaluation and Pittsburgh sleep quality index （PSQI） were used. The tinnitus handicap inventory （THI） scores were compared before and after SGB intervention. Correlation analysis and linear regression equations were employed to identify the potential indicators predicting the effectiveness of SGB intervention. Statistical analysis was performed by SPSS 24.0 software. ResultsBy April 2023， a total of 107 patients with chronic subjective tinnitus had undergone SGB intervention， including 67 male and 40 female， with a mean age of （45.32±11.40） years old and an average tinnitus history of （20.32±24.64） months ［16 （12~20）］. Only 7 patients （6.54%） quitted the intervention for personal reasons， which demonstrated good compliance with the intervention. No patients experienced adverse reactions such as infection at the injection site， hematoma， nerve injury， local anesthetic intoxication and so on， which revealed good safety. After SGB intervention， THI scores decreased to below 36 points in 77 patients and decrease by 10 points or more in 12 of the remaining patients， with a total effective rate of 89%. A paired sample t-test showed a significant difference in THI scores before and after SGB intervention （t=15.575， P<0.001）， indicating good improvement. Pearson correlation analysis suggested that pre-intervention THI scores and subjective tinnitus loudness were significantly positively correlated with the improvement level of THI scores （P<0.05）. Further stepwise linear regression analysis found that "pre-intervention THI scores" had statistical significance （P<0.001）， with a regression coefficient of 0.308， predicting a 17.4% improvement level in THI scores. ConclusionsDue to its good and safe short-term effects， SGB intervention can be used as a supplementary option for chronic subjective tinnitus when other interventions are not ideal， especially for patients with higher THI scores. However， further research is needed to clarify the long-term efficacy and underlying mechanisms， in order to establish a more solid theoretical basis for SGB intervention in the treatment of subjective tinnitus.

ObjectiveThis study aims to explore the effect of ultrasound-guided superficial parasternal intercostal plane block on the quality of recovery and postoperative analgesia in patients undergoing sternotomy cardiac surgery. MethodsA total of 64 patients undergoing sternotomy cardiac surgery were selected for this study. They were randomly divided into two groups： one group received a superficial parasternal intercostal plane block with ropivacaine （the ropivacaine group）， while the other was given normal saline （the normal saline group）. The primary outcome was the Quality of Recovery-15 （QoR-15） score on postoperative day 1 in both groups， accompanied by a comparative analysis of the pain score and opioid usage. ResultsCompared with the normal saline group， the ropivacaine group exhibited a significantly higher QoR-15 score on postoperative day 1［（89.60±13.24） vs （81.18±12.78）， P=0.012］. The numerical rating scale at rest was significantly lower［（3.03±0.72） vs （4.26±0.93）， P<0.001］， and the numerical rating scale during coughing was also significantly reduced ［（4.40±0.89） vs （5.44±1.05）， P<0.001］. Concurrently， the cumulative morphine equivalent consumption during the initial 24 h postoperatively was significantly lower in patients who were administered the ropivacaine ［14.15 （4.95～30.00） mg vs 40.50 （19.25～68.18） mg， P=0.002］， and there was also a notable decrease in the rescue analgesia ［0.00 （0.00～0.00） mg vs 0.00 （0.00～100.00） mg， P=0.007］. ConclusionUltrasound-guided superficial parasternal intercostal plane block can significantly enhance the overall quality of recovery in patients undergoing sternotomy cardiac surgery on postoperative day 1. The technique contributes to improved postoperative analgesic effects and a reduction in opioid usage， thereby facilitating early postoperative recovery.
Résumé
@#Among pregnant women, 1-2% are anti-Ro positive and while half of them have symptoms of connective tissue disease, the rest are asymptomatic. The presence of anti-Ro is of concern because of the risk of congenital heart block in the child. We report the case of an asymptomatic 27-year-old G2P1(1001) woman, who presented with persistent fetal bradycardia in her 21st week of gestation (AOG) and was found to have elevated titers for anti-Ro (>320 U/ml). Hydroxychloroquine 200 mg/day and prednisone 10 mg/day were given from the 33rd week of gestation up until the delivery. At 37 weeks AOG, she delivered a live male neonate with a complete heart block. On the 6th day of life, the infant remained bradycardic, hence a pacemaker was inserted and heart rate maintained at 100-120 bpm. On subsequent follow-ups, the mother and child did not develop any systemic manifestations and the infant was thriving well. While a diseased condition may not be apparent in a pregnant anti-Ro positive woman, the risk of neonatal lupus (NL) is demonstrated in this patient’s case. This report illustrates how prenatal care of an asymptomatic woman led to the discovery of a fetal abnormality and served to prepare the family and the medical team to ably handle the birth and subsequent care of a neonate with NL.

@#Phantom limb pain (PLP) is difficult to control, and patients frequently exhibit inadequate relief from medications or encounter unbearable side effects. We present here a novel application of erector spinae plane (ESP) block to manage PLP. Our patient is a 23-year-old, college student, diagnosed with high-grade osteosarcoma of the right humerus who underwent a right shoulder disarticulation. He reported PLP despite multimodal analgesia postoperatively. An ESP block using a high-frequency linear probe ultrasound was performed. A G23 spinal needle was advanced inplane toward the right T3 transverse process. After negative aspiration, 20 mL of therapeutic solution containing bupivacaine 0.25%, lidocaine 1%, epinephrine 5 mcg/ml, and 40 mg methylprednisolone was injected. After the procedure, the patient reported that his PLP went down to NRS 1/10. He consistently reported to have an NRS score of 0-1/10 on succeeding consultations despite discontinuation of opioid and pregabalin. In literature, ESP block has been used as a regional technique for shoulder disarticulation surgery and other neuropathic pain conditions, but no account has shown its use for PLP treatment. The procedure was successfully done to alleviate the upper extremity phantom limb pain, significantly reduce analgesic requirements, and improve tolerance of physical therapy and overall quality of life.

@#Objective Verify the improvement effect of rhomboid intercostal and sub-serratus plane block on the quality of early postoperative recovery in patients undergoing thoracoscopic radical resection of lung cancer;Comparison of the differences in the effect of regional block at different timing on improving the quality of early postoperative recovery.Methods A total of 75 patients,aged 18 to 75 years,with ASA gradeⅠ-Ⅱ,who were scheduled to undergo thoracoscopic radical resection of lung cancer from January 2022 to January 2023 were selected.Randomly divided into three groups:blank control group(Group C),preoperative block group(PR group),and postoperative block group(PO group).The PR group and the PO group received ultrasound guided rhomboid intercostal and sub-serratus plane block in the preoperative anesthesia preparation room and postoperative anesthesia recovery room,respectively,with a dosage of 0.375％ropivacaine 30ml.Evaluate the postoperative recovery quality of patients at 24 and 48 hours using the postoperative recovery quality rating scale(QoR-40)scoring scale.Record numeric rating scale(NRS)pain scores in resting and active states at 0.5h,1h,2h,4h,8h,12h,24h,and 48h after surgery.Record the consumption of opioid drugs during and after surgery,the effective number of postoperative patient-controlled intravenous analgesia(PCIA)compressions,and the incidence of nausea and vomiting.Results Compared with Group C,the consumption of opioids during surgery in the PR group was significantly reduced.The QoR-40 score at 24 hours after surgery was significantly higher in the PR and PO groups.Significant reduction in NRS scores between 1-8 hours of rest and 1-12 hours of activity after surgery,and the effective times of PCIA compressions and opioid consumption were significantly reduced(P<0.05).Compared with the PR group,the PO group consumed more opioids during surgery and had a higher NRS score at 0.5 hours after surgery(P<0.05).There was no significant difference in postoperative QoR-40 scores,PCIA effective compressions,and opioid consumption;There was no statistically significant difference in the incidence of postoperative nausea and vomiting among the three groups.Conclusion Rhomboid intercostal and sub-serratus plane block can improve the early recovery quality of patients undergoing thoracoscopic radical resection of lung cancer,reduce the postoperative pain level of patients,and reduce the amount of opioids used in perioperative period,and its effectiveness has nothing to do with the blocking time.
Résumé
A 74-year-old man was diagnosed with infective endocarditis (IE) involving the aortic and tricuspid valves, ventricular septal defect (VSD), and complete atrioventricular block. He was admitted to a previous hospital with complaints of fever and neck pain, and he developed complete atrioventricular block during the course of his illness. An echocardiogram revealed severe aortic regurgitation, aortic valve vegetations, and a ventricular septal defect. He was then transferred to our hospital, and he underwent emergent surgery. The aortic valve cusps were calcified and thick, with significant cusp destruction. The vegetations partly extended to the subvalvular area of the right and non-coronary cusp. The vegetations also extended from the atrial septum to the tricuspid valve septal leaflet and perimembranous VSD. Ventricular septal reconstruction using the sandwich technique with two bovine pericardial patches, aortic valve replacement, and tricuspid valve replacement were performed. Postoperatively, he received antibiotic therapy for six weeks and was discharged from our hospital after the implantation of a cardiac resynchronization therapy pacemaker. Echocardiography showed no residual shunts. Our case suggests that the sandwich technique can be a useful method of septal reconstruction for IE with extensive destruction of the ventricular septum.

Abstract Background: The present study explored the role of continuous erector spinae plane (ESP) block for analgesia as well as its impact on pulmonary functions in patients with multiple rib fractures. Methods: Ten patients with multiple rib fractures were enrolled after getting informed and written consent. Ultrasound-guided ESP block was performed at the level midway between the fractured ribs followed by the insertion of the catheter. Pre- and post-block VAS score, hemodynamics, respiratory rate (RR), peripheral oxygen saturation (SpO2), inspiratory capacity (IC), blood gases (PaO2 and PCO2), and complications were compared. Results: Pain scores at rest as well as on movement showed a significant reduction from 5.9 and 7.5 pre block to 1.6 and 2.5 respectively at 96 hours (p < 0.0001). Similarly, RR, SpO2, IC, and PaO2 were significantly better after the block placement (p < 0.001). Conclusion: Continuous ESP block provide adequate analgesia with better respiratory functions in patients with multiple rib fractures.
Résumé
Abstract Objective: This trial aimed to identify the Minimum Effective Concentration (MEC90, defined as the concentration which can provide successful block in 90% of patients) of 30 mL ropivacaine for single-shot ultrasound-guided transmuscular Quadratus Lumborum Block (QLB) in patients undergoing Total Hip Arthroplasty (THA). Methods: A double-blind, randomized dose-finding study using the biased coin design up-and-down sequential method, where the concentration of local anesthetic administered to each patient depended on the response from the previous one. Block success was defined as a Numeric Rating Scale (NRS) score during motion ≤ 3 at 6 hours after arrival in the ward. If the block was successful, the next subject received either a 0.025% smaller dose (probability of 0.11) or the same dose (probability of 0.89); otherwise, the next subject received a 0.025% higher ropivacaine concentration. MEC90, MEC95 and MEC99 were estimated by isotonic regression, and the corresponding 95% Confidence Intervals (95% CIs) were calculated by the bootstrapping method. Results: Based on the analysis of 52 patients, MEC90, MEC95, and MEC99 of ropivacaine for QLB were estimated to be 0.352% (95% CI 0.334-0.372%), 0.363% (95% CI 0.351-0.383%), and 0.373% (95% CI 0.363-0.386%). The concentration of ropivacaine at 0.352% in a volume of 30 ml can provide a successful block in 90% of patients. Conclusions: For ultrasound-guided transmuscular QLB in patients undergoing THA, 0.352% ropivacaine in a volume of 30 ml can provide a successful block in 90% of patients. Further dose-finding studies and large sample size are required to verify the concentration.
Résumé
Abstract Background: The costoclavicular approach to brachial plexus block may have a more favorable anatomy than the classic infraclavicular approach. However, there are conflicting results in the literature regarding the comparative effectiveness of these two techniques. Methods: We systematically searched for Randomized Controlled Trials (RCTs) comparing costo-clavicular with infraclavicular brachial plexus blocks for upper extremity surgeries on MEDLINE, EMBASE, and Ovid. The outcomes of interest were sensory and motor block onset times, performance times, block failure, and complication rate. We performed statistical analyses using RevMan 5.4 and assessed heterogeneity using the Cochran Q test and I2 statistics. We appraised the risk of bias according to Cochrane's Risk of Bias 2 tool. Results: We included 5 RCTs and 374 patients, of whom 189 (50.5%) were randomized to undergo costoclavicular block. We found no statistically significant differences between the two techniques regarding sensory block onset time in minutes (Mean Difference [MD = −0.39 min]; 95% CI −2.46 to 1.68 min; p = 0.71); motor block onset time in minutes (MD = −0.34 min; 95% CI −0.90 to 0.22 min; p = 0.23); performance time in minutes (MD = −0.12 min; 95% CI −0.89 to 0.64 min; p = 0.75); incidence of block failure (RR = 1.59; 95% CI 0.63 to 3.39; p = 0.63); and incidence of complications (RR = 0.60; 95% CI 0.20 to 1.84; p = 0.37). Conclusion: This meta-analysis suggests that the CCV block may exhibit similar sensory and motor onset times when compared to the classic ICV approach in adults undergoing distal upper extremity surgery, with comparable rates of block failure and complications.
