Action of galvanic currents on needles during percutaneous needle electrolysis

Abstract: Background The use of galvanic currents (GC), during percutaneous needle electrolysis (PNE) can make needles release metals and therefore decrease their diameter and increase resistance. If this were very marked, this could increase the temperature of the needle during use of the same. Furthermore, the loss of materials such as zinc, can trigger allergic reactions in people who are sensitive to these metals. Aim to evaluate modifications of needles during the application of GC in PNE. Methods The resistance was evaluated using a Digital multimeter Velleman DVM92. The GC was generated using the Physio Invasiva device by Prim (3 mA during 3 seconds, 3 applications were performed). For each needle, resistance of the proximal and distal area was evaluated (insertion) and the % of variation was calculated. 20 Physio Invasiva Needles measuring 0.30 × 40mm were evaluated and inserted in mice. A Quante 600 scanningmicroscope was used as well as a microanalysis device based on diffusion by RX Oxford Instruments (Universidad Rovira i Virgili). The protocols used were: A) 3mA during 3 seconds and 3 applications (Physio Invasiva by BRUMA Center-Tarragona (6 needles) and from the MV Clinic-Madrid (9 needles) in humans and from the UHN laboratory UHN (10 needles) in animals; B) 3mA during 3 seconds and 10 applications, 5 needles were evaluated in animals; C) 3mA during 3 seconds and 50 applications, 5 needles were evaluated in animals. Results No change was obtained in the proximal-distal resistance (0.4% ± 3.33). No loss of any of the metals occurred in the needles subjected to the protocol of 3/3/3 nor the protocol 3/3/10. However, in the 3/3/10 protocol, statistically significant losses were obtained for all the metals present. Conclusion Physio Invasiva needles measuring 0.30 × 40mm do not shed metals nor modify their morphology during the intervention, therefore, the needle diameter of the needle does not decrease. Only exceptionally, when the number of applications is large, is there a loss of material.
Antecedentes El uso de la corriente galvánica (CG), durante la electrolisis percutánea musculoesquelética (EPM) puede hacer perder metales de las agujas y por tanto disminuir su diámetro y aumentar la resistencia. Caso de ser muy marcado podría aumentar la temperatura de la aguja durante su uso. Por otro lado, la pérdida de materiales como el Zinc puede desencadenar reacciones alérgicas en personas sensibles a estos metales. Objetivo Evaluar modificaciones de las agujas durante la aplicación de CG en EPM. Metodología La resistencia se evaluó con Multi voltímetro Digital Velleman DVM92. La CG se generó con el equipo Physio Invasiva Prim (3 mA durante3 segundos, se realizaron 3 aplicaciones). De cada aguja se evaluó la resistencia del área proximal y del área distal (de inserción) y se calculó el % de variación. Se han evaluado 20 Agujas Physio Invasiva 0.30 × 40mm insertadas en ratones. Se utilizó el microscopio electrónico de barrido Quanta 600 y el equipo de microanálisis por difusión de RX Oxford Instruments (Universidad Rovira i Virgili). Los protocolos utilizados han sido: A) 3mA durante 3 segundos y 3 aplicaciones (Physio Invasiva del Centro BRUMA-Tarragona (6 agujas) y del Centro MV Clinic-Madrid (9 agujas) en humanos y del Laboratorio UHN (10 agujas) en animales; B) 3mA durante 3 segundos y 10 aplicaciones, se evaluaron 5 agujas en animales;C) 3mA durante 3 segundos y 50 aplicaciones, se evaluaron 5 agujas en animales. Resultados No se obtuvo ningún cambio en la resistencia próximo-distal (0.4% ± 3.33). No se produce ninguna pérdida de ninguno de los metales en las agujas expuestas al protocolo de 3/3/3 ni al protocolo 3/3/10. Sin embargo, en el protocolo 3/3/10 se obtienen perdidas estadísticamente significativas de todos los metales presentes. Conclusión Las agujas Physio Invasiva 0.30 × 40mm no pierden metales ni modifican su morfología durante la intervención de manera que tampoco disminuye el diámetro de la aguja. Solo excepcionalmente cuando el número de aplicaciones es muy grande hay perdida de material.
