Excerpt:
"Regional anesthesia offers many advantages over procedural sedation for fracture and dislocation reduction. In general, a successful block will provide complete anesthesia within the desired nerve distribution without the potential complications of procedural sedation. In addition, regional anesthesia does not require a prolonged postprocedural observation period following reduction, thus shortening ED length of stays and decreasing the requirement for nursing care.This is a commonly used block to provide anesthesia to a finger or toe. The digits possess two dorsal and two palmar nerves that run along the phalanges in the 2, 4, 8, and 10 o'clock positions. The ring block is successfully performed by blocking these nerves in a circumferential pattern around the base of the digit. The half-ring block is an alternative method with similar success in which anesthetic is injected on either side of the base of the digit (Fig. 2–1 and Video 2–1). For blocking the great toe, a circumferential ring of anesthetic is recommended due to the greater distance between the nerves.The radial nerve is blocked at the wrist using..."
