Ultrasound-guided posterior approach for the placement of a continuous interscalene catheter.
The posterior approach to performing a continuous brachial plexus block at the level of the nerve roots has been described using traditional superficial landmarks. We describe an ultrasound-guided approach for the placement of a continuous interscalene brachial plexus catheter at the level of the nerve roots using a posterior approach. In addition, we provide the clinical characteristics of the first 16 catheters placed at our institution utilizing this approach. ⋯ Results suggest the use of ultrasound for placing a continuous interscalene nerve catheter via the posterior approach is a viable technique that offers an alternative to the more conventional non-image-guided superficial landmark techniques.

Anatomic variations of the obturator nerve in the inguinal region: implications in conventional and ultrasound regional anesthesia techniques.
This study was conducted to provide a thorough description of the variability in the obturator nerve branching pattern in the inguinal region. ⋯ High anatomic variability in the obturator nerve's divisions and subdivisions does exist, and explains the difficulty frequently encountered in the application of regional anesthetic techniques.
