Randomized Controlled TrialTreatment of Postmastectomy Pain With Ambulatory Continuous Paravertebral Nerve Blocks: A Randomized, Triple-Masked, Placebo-Controlled Study.
We aimed to determine with this randomized, triple-masked, placebo-controlled study if benefits are afforded by adding a multiple-day, ambulatory, continuous ropivacaine paravertebral nerve block to a single-injection ropivacaine paravertebral block after mastectomy. ⋯ After mastectomy, adding a multiple-day, ambulatory, continuous ropivacaine infusion to a single-injection ropivacaine paravertebral nerve block results in improved analgesia and less functional deficit during the infusion. However, no benefits were identified after infusion discontinuation.

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.

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.
