Regional anesthesia and pain medicine
-
The perception of high resistance during injection of a local anesthetic during regional anesthesia may indicate intraneural injection. Anesthetists' ability to detect high resistance by "syringe feel" has been questioned in the past. The aim of our study was to investigate the anesthetist's ability to detect abnormal resistance to injection using an animal model. ⋯ Under the conditions of this study model, anesthetists were unable to correctly identify intraneural injection by syringe feel during simulated regional anesthesia.
