Abstract
Phenolic stellate ganglion blockade caused triparesis in one patient, and phenolic neurolysis of cervical posterior roots caused respiratory arrest in another. These complications illustrate the dangers of the spread of phenol beyond the intended site of neurolysis with resultant local anesthesia, direct neural damage, vascular damage, and infarcts.
