Ultrasound-guided PNBs are universally taught across residency programs in the United States. Most teaching physicians believe that ultrasound increases PNB's success and improves safety of regional anesthesia. Barriers to ultrasound use are lack of faculty training and unavailability of ultrasound equipment.
With ultrasound guidance, the regional anesthesiologist has yet another tool to enhance both the accuracy and success of peripheral-nerve blockade. This article serves to display the most clinically relevant nerve blocks utilized in the perioperative setting. It is meant to be used as a clinical starting point for the development of regional anesthesia skills.
Ambulatory continuous infusions are typically associated with few serious complications and a favourable safety profile. This case demonstrates that unexpected complications can still occur even after days of normal operation. Based on our previous experience, we believe this to be a rare but potentially serious event that requires awareness by those discharging patients with continuous infusions of local anesthetics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
