简要总结
Ultrasound have been shown to improve the time needed to locate and block nerves in the non obese population. However, its utility is still unknown in the obese population. Ultrasound is known to produce poorer quality images in the obese population. This study aims to find out if it is a better tool for nerve localization compared to the traditional nerve stimulation technique.
详细描述
This is a single blinded randomized controlled trial comparing the procedural time for a sciatic nerve block via the lateral popliteal approach using ultrasound compared with nerve stimulation.
24 patients will be randomly selected to determine if the patient will receive their sciatic block using an ultrasound or a nerve stimulation technique.
Patients chosen to receive the ultrasound technique will have their blocks performed by attending regional anesthesiologist who are experts at ultrasound guided sciatic nerve blocks via the lateral popliteal approach.
Patients chosen to receive the nerve stimulation technique will have their blocks performed by attending regional anesthesiologist who are experts at nerve stimulation sciatic nerve blocks via the lateral popliteal approach.
