Abstract
Introduction: Delivering requisite anesthesia for endovascular treatment of dysfunctional arteriovenous fistulas (AVFs) under a targeted nerve block can achieve reasonable analgesia. We evaluated the efficacy and safety of ultrasound-guided selective nerve block (SNB) during percutaneous transluminal angioplasty (PTA) of dysfunctional arteriovenous access.
Methods: Two hundred forty-six patients with dysfunctional radiocephalic AVF undergoing PTA were enrolled in this prospective, randomized controlled trial at the Department of Nephrology, Haidian Hospital, Peking University Third Hospital from June 1, 2022, to August 31, 2023. The patients were randomized into either the SNB group (SNB group, n = 123) or the local infiltration anesthesia group (LA group, n = 123). A visual analog scale (VAS) from no pain (= 0) to worst pain possible (= 10) was used to assess the pain intensity. Patient and operator satisfaction were graded from 0 to 2: 0, not satisfied at all; 1, partially satisfied; 2, satisfied. The AVF patency at 1 and 3 months after PTA was also evaluated.
Results: Compared with the LA group, the SNB group had significantly lower VAS scores (Z = -7.193, p < 0.001) and required fewer additional anesthetics during the operation (χ2 = -4.847, p = 0.028). Patient and operator satisfaction were significantly higher in the SNB group (p < 0.05). Eight patients in the SNB group encountered grade 3 motor paralysis after the operation, and they all recovered within 60 min. There was no significant difference in primary patency rates of the fistula between the two groups either at 1 month or 3 months after the operation (p > 0.05).
Conclusion: Compared with LA, ultrasound-guided SNB has advantages over the LA during endovascular treatment of dysfunctional hemodialysis (HD) fistulas. It can provide safe and efficient analgesia with excellent procedural satisfaction in HD patients.
期刊介绍：
Practical information on hemodialysis, hemofiltration, peritoneal dialysis and apheresis is featured in this journal. Recognizing the critical importance of equipment and procedures, particular emphasis has been placed on reports, drawn from a wide range of fields, describing technical advances and improvements in methodology. Papers reflect the search for cost-effective solutions which increase not only patient survival but also patient comfort and disease improvement through prevention or correction of undesirable effects. Advances in vascular access and blood anticoagulation, problems associated with exposure of blood to foreign surfaces and acute-care nephrology, including continuous therapies, also receive attention. Nephrologists, internists, intensivists and hospital staff involved in dialysis, apheresis and immunoadsorption for acute and chronic solid organ failure will find this journal useful and informative. ''Blood Purification'' also serves as a platform for multidisciplinary experiences involving nephrologists, cardiologists and critical care physicians in order to expand the level of interaction between different disciplines and specialities.
