A Prospective Comparison of Procedural Sedation and Ultrasound-guided Interscalene Nerve Block for Shoulder Reduction in the Emergency Department.

There was no difference in pain level or satisfaction when compared to procedural sedation patients. Blaivas M, Adhikari S, Lander L. Acad Emerg Med. 2011 Aug 30. [Epub ahead of print] PMID: 21883635
