RESUMO
Antecedentes: Casi el 60-80% de la población padece de dolor de espalda, lo cual convierte a esta situación en una de las causas más comunes de consulta. Uno de los tratamientos más efectivos para el dolor lumbar es la discectomía endoscópica percutánea transforaminal, que requiere diferentes opciones anestésicas. Nuestro objetivo primario fue probar la hipótesis de si el bloqueo en el plano del músculo erector de la columna (ESP) bilateral con sedación es similar a la infiltración tradicional local de anestésico con sedación. Materiales y métodos: Se asignó aleatoriamente a cincuenta y dos pacientes sometidos a discectomía endoscópica percutánea transforaminal a dos grupos: el G1 recibió sedación intravenosa con anestesia local infiltrativa; G2 recibió sedación intravenosa con ESP bilateral. Resultado primario: cantidad de fentanilo y propofol durante la cirugía. Resultados secundarios: episodios adversos durante la sedación utilizando la herramienta de reporte sobre episodios adversos de la sedación de la Society of Intravenous Anaesthesia (SIVA), nivel de sedación postoperatoria utilizando la escala Richmond Agitation-Sedation Scale (RASS), intensidad del dolor tras la cirugía utilizando la escala visual analógica (EVA), umbral del dolor mecánico (MPT) utilizando microfilamentos de von Frey, medido en ambas extremidades inferiores, y satisfacción con la analgesia aplicando la escala Likert de 5 puntos. Resultados: La cantidad de fentanilo, propofol y el nivel de sedación postoperatoria fueron significativamente menores en G2 (p<0,001). No se produjo diferencia en cuanto a intensidad del dolor, satisfacción con la analgesia y umbral del dolor mecánico tras la cirugía en ambos grupos. No se produjeron episodios adversos en el grupo G2 en comparación con G1 (2 pacientes descriptores del riesgo mínimo, 5 descriptores del riesgo menor y 1 descriptor del riesgo centinela) que requirieron medicación adicional o ventilación de rescate...(AU)
Background: About 60% to 80% of the population suffers from back pain, making it one of the most common health complaints. One of an effective treatments of low back pain is transforaminal percutaneous endoscopic discectomy (TPED) which requires different options for anaesthesia. Our primary objective was to test the hypothesis if the bilateral erector spine plane block (ESP) with sedation is similar to traditional infiltrative local anaesthesia with sedation. Materials and methods: Fifty-two patients that underwent TPED were randomly assigned in two groups: G1 received intravenous sedation with infiltrative local anaesthesia; G2 received intravenous sedation with bilateral ESP. Primary outcome: amount of fentanyl and propofol during surgery. Secondary outcomes: adverse events during sedation employing World Society of Intravenous Anaesthesia (SIVA) adverse sedation event reporting tool, level of postoperative sedation with Richmond Agitation-Sedation Scale (RASS), intensity of pain after surgery engaging a visual analogue scale (EVA), the mechanical pain threshold (MPT) with von Frey monofilaments measured on both lower extremities, satisfaction with analgesia applying 5-point Likert scale. Results: Amount of fentanyl, propofol and level of postoperative sedation was significantly lower in G2 (p<0.001). There was no difference in intensity of pain, satisfaction with analgesia, and the mechanical pain threshold after surgery in both groups. There were no adverse events in G2 group in contradistinction to G1 (2 patients minimal risk descriptors, 5 minor risk descriptors and 1 sentinel risk descriptors) which required additional medication or rescue ventilation...(AU)

BACKGROUND: Around 60%-80% of the population suffers from back pain, making it one of the most common health complaints. Transforaminal percutaneous endoscopic discectomy (TPED) is an effective treatment for low back pain that can be performed using different anaesthesia techniques. Our primary objective was to test the hypothesis that bilateral Erector spinae plane block (ESP) plus sedation is equally effective as traditional local infiltration anaesthesia plus sedation in TPED. MATERIALS AND METHODS: Fifty-two patients undergoing TPED were randomly assigned to 2 groups: G1 - intravenous sedation with local infiltration anaesthesia; G2 - intravenous sedation with bilateral ESP. PRIMARY OUTCOME: volume of fentanyl and propofol administered during surgery. SECONDARY OUTCOMES: adverse events during sedation reported using the World Society of Intravenous Anaesthesia (SIVA) adverse sedation event tool, level of postoperative sedation measured on the Richmond Agitation-Sedation Scale (RASS), intensity of postoperative pain on a visual analogue scale (VAS), mechanical pain threshold (MPT) measured with von Frey monofilaments on both lower extremities, patient satisfaction with analgesia on 5-point Likert scale. RESULTS: Volume of fentanyl, propofol, and level of postoperative sedation was significantly lower in G2 (pâ¯<â¯0.001). There was no difference between groups in intensity of pain, patient satisfaction with analgesia, and mechanical pain threshold after surgery. There were no adverse events in G2, but in G1 2 patients presented minimal risk descriptors, 5 presented minor risk descriptors, and 1 presented sentinel risk descriptors that required additional medication or rescue ventilation. CONCLUSIONS: The ESP was equal to local infiltration anaesthesia in terms of intensity of pain, mechanical pain threshold after surgery, and patient satisfaction; however, ESP reduced the volume of intraoperative fentanyl and propofol, thereby reducing the adverse effects of sedation.
