Randomized Controlled Trial Clinical TrialBier block with methylprednisolone and lidocaine in CRPS type I: a randomized, double-blinded, placebo-controlled study.
To investigate the effect of intravenous regional anesthesia (Bier block) with methylprednisolone and lidocaine in complex regional pain syndrome (CRPS) type I in a randomized, double-blinded, and placebo-controlled study. ⋯ Bier block with methylprednisolone and lidocaine in CRPS type I does not provide long-term benefit in CRPS, and its short-term benefit is not superior to placebo.

Comparative StudyThe use of magnetic resonance imaging to evaluate the accuracy of a handheld ultrasound machine in localizing the sciatic nerve in the popliteal fossa.
Ultrasound has become an increasingly popular modality in facilitating the performance of peripheral nerve blocks. There is a paucity of data describing techniques of ultrasound-guided sciatic nerve blocks. By using magnetic resonance imaging (MRI) as a gold standard, the objective of this study was to describe the ability of a handheld ultrasound machine to accurately locate the sciatic nerve. ⋯ The data presented here suggest that the specific ultrasound machine evaluated in this study can accurately localize the sciatic nerve in the popliteal fossa.
