A 58-year-old woman was found to have bilateral ptosis and downward gaze deviation immediately after elective shoulder surgery with general anesthesia and supraclavicular nerve block. A code stroke was activated due to concern for the neurologic process, but neuroimaging did not reveal acute changes or vascular abnormality. Her symptoms gradually resolved in the following hours with supportive care and were ultimately deemed to be related to anesthetic and transdermal scopolamine exposures layered upon her underlying comorbidities. Transient bilateral ophthalmoplegia after general anesthetics has been previously described; drug effect should be considered in the differential of this alarming presentation, which can mimic acute stroke and/or Horner syndrome.
Keywords: adverse drug effect; code stroke; eye ptosis; gaze palsy; general anesthesia; nerve block; ophthalmoplegia; scopolamine; stroke mimic.
