Randomized Controlled Trial Comparative Study Clinical Trial
The sciatic nerve block in emergency settings: a comparison between a new anterior and the classic lateral approaches.
Anterior and lateral approaches to the sciatic nerve block are performed with the patient in the supine position. This could be an important advantage when mobilization to the limb involved is limited or painful, particularly in emergency conditions. The aim of this prospective, randomized study was to compare these two sciatic nerve blockades performed in an emergency setting. ⋯ These data suggest that both techniques are of similar value in an emergency setting.

Regional anesthesia can be the technique of choice for selected ambulatory surgery procedures, but in spite of its benefits, it has an inherent failure rate even in experienced hands. We examine the efficacy and factors associated with failure of ambulatory regional anesthesia techniques. ⋯ High BMI and ASA IV are independent risk factors for block failure in ambulatory surgery patients.

The purpose of this study was to determine the factors associated with false-positive medial branch blocks (MBB), the nerve blocks used to diagnose facet arthropathy, in soldiers and retirees. ⋯ Although a high incidence of epidural and foraminal spread occurs during the performance of MBB, this is unlikely to be a significant cause of false-positive blocks.
