With great interest we have read the article by Cappelleri et al.1  describing a study in which they performed intentional intraneural injection and completed clinical and neurophysiologic examinations at 5 weeks and 6 months. The intraneural injection reduced the dose of local anesthetics and provided a faster onset and greater success rate of local anesthesia; however, persistent electrophysiologic changes suggested possible axonal damage that might never recover. There are a few points we would like to present.
First, the authors stressed that one purpose of their method was to decrease the risk of systemic local anesthetic toxicity. Actually, the incidence of systemic toxicity after ultrasound-guided regional block itself is rare.
