Responses against electrical stimulation received in the deltoid muscle, pectoral major muscle, triceps muscle or biceps muscle were lost under 1 Hz and 0.5 mA and it was noted that the patient did not bleed following aspiration; then, 20 ml pre-operatively prepared 0.25% bupivacaine 10 mL 0.5% bupivacaine + 10 mL 0.9% NaCl was injected and the block was completed.
Las respuestas a la estimulación eléctrica en el músculo deltoides, músculo pectoral mayor, músculo tríceps o bíceps fueron perdidas bajo 1 Hz y 0,5 mA, y se observó que el paciente no sangró después de la aspiración. A continuación, fueron inyectados 20 mL de bupivacaína al 0,25% preparados antes de la operación 10 mL de bupivacaína al 0,5% + 10 mL de NaCl al 0,9%, y el bloqueo se completó.
