Randomized Controlled Trial Comparative StudyUltrasound- or nerve stimulation-guided wrist blocks for carpal tunnel release: a randomized prospective comparative study.
We hypothesized that ultrasound-guided wrist blocks may be faster to perform, and may increase success rate, compared with nerve stimulation-guided wrist blocks. ⋯ This randomized prospective study demonstrates that ultrasound-guided wrist nerve blocks are as efficient as those performed with nerve stimulation.

Randomized Controlled TrialAnalgesic effect of lidocaine patch 5% in the treatment of acute herpes zoster: a double-blind and vehicle-controlled study.
Although lidocaine patch 5% has been widely used for postherpetic neuralgia, its analgesic effect on the intense pain associated with acute herpes zoster has not been investigated because of its potential hazard to damaged skin. ⋯ This study demonstrates that lidocaine patch 5%, applied twice a day, could serve as a well tolerated and effective modality to relieve moderate to severe pain associated with acute herpes zoster presumably through its pharmacological action and physical barrier effect on sensitized skin.

New model for learning ultrasound-guided needle to target localization.
The acquisition of technical skills for the novice learner presents challenges for students and teachers alike. With the introduction of ultrasound techniques in regional anesthesia, there has been interest from residents, fellows, and staff to acquire the skills necessary to incorporate this technology into their everyday practice. However, as both ultrasound machines and commercial target models are inherently costly, there are often issues of accessibility that may affect the opportunity to learn the desired skills. ⋯ This report presents an inexpensive, variable complexity model for learning ultrasound-guided needle-to-target localization.
