The use of 10-15 micrograms epinephrine as an epidural test-dose is controversial. Isoproterenol would be a better alternative. However, before 5 micrograms isoproterenol can be incorporated in an epidural test-dose, neurotoxicological studies have to be performed. The present study was designed to assess spinal somatosensory evoked potentials (spinal SSEP) before and after epidural isoproteronol.
