Randomized Controlled Trial Comparative StudyUltrasound improves the success rate of a tibial nerve block at the ankle.
The tibial nerve provides the majority of sensation to the foot. Although multiple techniques have been described, there exists little evidence-based medicine evaluating different techniques for blocking the tibial nerve at the ankle. We hypothesized that an ultrasound (US)-guided tibial nerve block at the ankle would prove more successful than a conventional approach based on surface landmarks. ⋯ In healthy volunteers, US guidance results in a more successful tibial nerve block at the ankle than does a traditional approach using surface landmarks.

Randomized Controlled Trial Comparative StudyClinical impact of epidural anesthesia simulation on short- and long-term learning curve: High- versus low-fidelity model training.
Epidural anesthesia is a technically challenging regional anesthetic technique that can be difficult to teach to novices. Epidural simulators are now available to allow realistic training within a safe and controlled environment before attempting the procedure on patients. Potentially, this may improve skill acquisition by novice residents. The purpose of this study was to examine the effect of a high-fidelity epidural anesthesia simulator on residents' ability to perform their first labor epidurals and on their learning curve compared with a group having training with a low-fidelity model. ⋯ Our study shows that a simple model can be as useful for learning how to place an epidural catheter as an expensive anatomically correct simulator. New and more technologically advanced simulators should be compared against lower fidelity models to establish their utility and cost-effectiveness.
