ABSTRACT
We report the effects of induced ultrasonic lesions on the sciatic nerve of the rat. Using different level of intensity (5 to 35%) and time exposure (5 to 60 seconds) for each application, we study the effects by action potential recording, microphotography and histological study. The nerve remains unaltered for low intensity (5 to 10%) until a time exposure of 20 seconds. Beyond that level, a progressive severity of the lesion is documented from oedema to contusion. A safe use of the surgical ultrasonic aspiration in the vicinity of nerves and roots must have a low intensity level, reducing the risks of direct contact between nerve and sonoprobe.
