Randomized Controlled Trial Comparative StudyA Randomized Comparison of the Efficacy of 2 Techniques for Piriformis Muscle Injection: Ultrasound-Guided Versus Nerve Stimulator With Fluoroscopic Guidance.
Piriformis muscle injections are most often performed using fluoroscopic guidance; however, ultrasound (US) guidance has recently been described extensively in the literature. No direct comparisons between the 2 techniques have been performed. Our objective was to compare the efficacy and efficiency of fluoroscopic- and US-guided techniques. ⋯ Ultrasound-guided piriformis injections provide similar outcomes to fluoroscopically guided injections without differences in imaging, needling, or overall procedural times.

Randomized Controlled TrialUltrasound-Guided Single-Penetration Dual-Injection Block for Leg and Foot Surgery: A Prospective, Randomized, Double-blind Study.
A single-penetration dual-injection block of the sciatic and saphenous nerves was faster to perform but equally effective as traditional techniques.

Case ReportsAn Epidural Blood Patch Causing Acute Neurologic Dysfunction Necessitating a Decompressive Laminectomy.
One risk with placement of an epidural blood patch (EDBP) is spinal cord or nerve root compression resulting from the epidural blood volume injected, a complication necessitating immediate surgical decompression. We could not find a previous report of this in the literature. Here, we review and discuss one such case. ⋯ A cauda equina syndrome from an epidural hematoma may occur as a rare complication of an EDBP, even with direct fluoroscopic guidance. Early diagnosis of symptoms and prompt surgical evacuation of an epidural hematoma is essential and may result in the resolution of symptoms. This complication remains a rare occurrence and should not deter the performance of an EDBP, when indicated.

Randomized Controlled Trial Comparative StudyDexmedetomidine Added to Ropivacaine Extends the Duration of Interscalene Brachial Plexus Blocks for Elective Shoulder Surgery When Compared with Ropivacaine Alone: A Single-Center, Prospective, Triple-Blind, Randomized Controlled Trial.
Dexmedetomidine 150 mcg significantly extends the duration of ropivacaine interscalene block by almost 30% without significant adverse effect.

Randomized Controlled TrialThe Effect of Nitrous Oxide Anesthesia on Early Postoperative Opioid Consumption and Pain.
Intraoperative nitrous oxide use does not improve post-operative analgesia or reduce opioid consumption.
