“…However, we experienced Grade IV obturator reflex even after complete main branch block of the right ON, and confirmed additional twitching of the pectineus muscle using ultrasound and a nerve stimulator. Therefore, we report this case with regard to various branching patterns of the ON at the inguinal crease (3)(4)(5). This report challenges the notion that anterior and posterior branch blocks are sufficient for complete ONB at the inguinal crease.…”

“…However, based on the experience of the described case, we are of the opinion that LA injection at a specific site at which main branches are expected to pass cannot guarantee complete ONB. Ishiyama et al (5) mentioned that multiple injections at fascial sites between adductor muscles might be necessary for complete ONB.…”

if a peripheral nerve block catheter was to be placed. In eight of 15 patients, a continuous peripheral nerve block catheter was inserted. After local anaesthetic injection ( Fig. 1D), the progress of the sensory block was assessed at 5 min intervals for the first 20 min. Sensory function was assessed as sensation to pinprick with a 23 gauge needle in the tibial (plantar area of the foot) and common peroneal (dorsal area of the foot) anatomical territories. Sensory function was graded as follows: zero, normal; one, moderate sensory loss; or two, complete sensory loss. Additionally, static and dynamic visual analogue scale scores were measured. A total score of three out of four was considered as successful sensory block.According to our results, the block success rate was 100%, and the static and dynamic visual analogue scale scores were zero at 20 min. No complications, including vascular puncture and local anaesthetic toxicity, were observed. A paraesthesia response was elicited in five of 15 patients. Postoperative neurological examination after recovery of sensory and motor function of the lower limb revealed no neurological deficit.A pocket-sized ultrasound linear probe seems to facilitate popliteal sciatic nerve block, providing a feasible and safe technique for perioperative pain management in patients with lower limb injuries. Further studies are required in order to validate our observations.
