El bloqueo del plano del músculo erector espinal antes de la litotricia extracorpórea por ondas de choque reduce el tiempo de fluoroscopia y facilita el tratamiento de la litiasis renal: estudio prospectivo aleatorizado / Erector spinae plane block prior to extracorporeal shock wave lithotripsy decreases fluoroscopy time and promise a comfortable procedure for renal stones: a prospective randomized study

Introducción y objetivos Comparar la eficacia del bloqueo del plano del erector espinal (BPEE) y el diclofenaco sódico intramuscular (IM) en términos del manejo del dolor y su impacto sobre el estado libre de cálculos en pacientes sometidos a litotricia extracorpórea de ondas de choque (LEOCh). Pacientes y materiales El estudio incluyó a pacientes sometidos a LEOCh por litiasis renal en nuestro centro. Los pacientes fueron asignados aleatoriamente a los grupos de BPEE (Grupo 1: n = 31) y de 75 mg de diclofenaco sódico IM (Grupo 2: n = 30). Se registraron los datos demográficos de los pacientes, el tiempo de fluoroscopia durante la LEOCh, el número de focalizaciones, el total de disparos administrados, el voltaje, las tasas libre de cálculos (TLC), el método de analgesia, el número de sesiones de LEOCh, la puntuación de la Escala Visual Analógica (EVA) la localización de los cálculos, el tamaño máximo de los cálculos, el volumen de los cálculos y las unidades Hounsfield (UH). Resultados Un total de 61 pacientes fueron incluidos en el estudio. No hubo diferencias estadísticamente significativas entre los dos grupos en cuanto al tamaño, el volumen y la densidad de los cálculos, la duración de la LEOCh, el total de disparos administradas, el voltaje, el índice de masa corporal (IMC), el estado libre de cálculos y la localización de los cálculos. El tiempo de fluoroscopia y el número de veces que fue necesario focalizar el cálculo fueron significativamente inferiores en el grupo 1 con respecto al grupo 2 (p:0,002, p:0,021, respectivamente). La puntuación EVA fue significativamente inferior en el grupo 1 en comparación con el grupo 2 (p<0,001). Conclusiones Observamos que la puntuación EVA del grupo BPEE era menor que la del grupo de diclofenaco sódico IM y, aunque no de manera estadísticamente significativa, conseguimos una tasa libre de cálculos más alta en la primera sesión en el grupo BPEE. ...

Introduction and Objectives To compare the efficacy of erector spinae plane block (ESPB) and intramuscular (i.m.) diclofenac sodium in regard to pain management and impact on stone-free status in patients undergoing SWL. Patients or Materials The study included patients who underwent SWL for kidney stones in our institution. The patients were randomly assigned to the ESPB (Group 1: n = 31) and i.m. 75 mg diclofenac sodium (Group 2: n = 30) groups. The demographic data of the patients, fluoroscopy time during SWL, number of need of targeting, total shocks given, voltage, stone free rates (SFR), analgesy method, number of SWL sessions, VAS score, stone location, maximum stone size, stone volume and Hounsfield unit (HU) were also recorded. Results A total of 61 patients were included the study. There was no statistically significant difference between the two groups according to stone size, volume and density, SWL duration, total shocks given, voltage, BMI, stone-free status and stone location. Fluoroscopy time and number of need for stone targeting were significantly lower in group 1 than group 2 (p:0.002, p:0.021, respectively). The VAS score was significantly lower for group 1 compared to group 2 (p<0.001). Conclusions We observed that the VAS score was lower in the ESPB group compared to i.m. diclofenac sodium group and although it was not statistically significant, we achieved a higher rate of stone-free status in the first session in ESPB group. Most importantly, the patients in the ESPB group were exposed to less fluoroscopy and radiation. (AU)

Erector spinae plane block prior to extracorporeal shock wave lithotripsy decreases fluoroscopy time and promise a comfortable procedure for renal stones: A prospective randomized study.

INTRODUCTION AND OBJECTIVES: To compare the efficacy of erector spinae plane block (ESPB) and intramuscular (i.m.) diclofenac sodium in regard to pain management and impact on stone-free status in patients undergoing SWL. PATIENTS AND MATERIALS: The study included patients who underwent SWL for kidney stones in our institution. The patients were randomly assigned to the ESPB (Group 1: n = 31) and i.m. 75 mg diclofenac sodium (Group 2: n = 30) groups. The demographic data of the patients, fluoroscopy time during SWL, number of need of targeting, total shocks given, voltage, stone free rates (SFR), analgesy method, number of SWL sessions, VAS score, stone location, maximum stone size, stone volume and Hounsfield unit (HU) were also recorded. RESULTS: A total of 61 patients were included the study. There was no statistically significant difference between the two groups according to stone size, volume and density, SWL duration, total shocks given, voltage, BMI, stone-free status and stone location. Fluoroscopy time and number of need for stone targeting were significantly lower in group 1 than group 2 (p = 0.002, p = 0.021, respectively). The VAS score was significantly lower for group 1 compared to group 2 (p < 0.001). CONCLUSIONS: We observed that the VAS score was lower in the ESPB group compared to i.m. diclofenac sodium group and although it was not statistically significant, we achieved a higher rate of stone-free status in the first session in ESPB group. Most importantly, the patients in the ESPB group were exposed to less fluoroscopy and radiation.
