Bloqueo mediofemoral para cirugía de pie: ¿existe relación entre la respuesta motora y la latencia? Correlación anatomoclínica

This approach provides an effective block with minimum latency in patients who have a flexion or extension motor response in the foot and/or fingers, inversion, or plantar flexion, which assumes that the injection has reached the common trunk of the sciatic or tibial nerve. However, a longer latency is associated with a peroneal motor response, particularly eversion.
