ObjectiveWe present an occurrence of a severe but transient neurologic complication after intraneural injection during an ultrasound-guided interscalene block.Case ReportA 36-year-old man underwent ultrasound-guided interscalene nerve blockade before shoulder incision and drainage. On postoperative day 1, he exhibited new-onset arm weakness with dysesthesias. Intraneural injection was recognized based on a retrospective review of the recorded ultrasound imaging. The symptoms persisted for more than 2 weeks and completely resolved by 6 weeks.ConclusionsOur report suggests that intraneural injection during ultrasound-guided interscalene block carries a risk of neurologic complications.
