[Severe lightning limb pain induced by spinal anesthesia].
We report a case in which spinal anesthesia induced a severe lightning limb pain. A 71-year-old man presented for prostate biopsy. Preanesthetic examinations revealed slight hypesthesia in the L 5-S 1 dermatomal segments in the right leg. The patient reported that he had received "local anesthetic" in the lumbar spine 16 years previously because of severe lumbago, and that his hyposthesia had originated from the "local anesthetic". Unfortunately we had no way to know the anesthetic technique performed 16 years ago. The spinal anesthesia was uneventfully introduced with a 25 G Quincke needle at the L 3-4 interspace using 2.0 ml 0.3% hyperbaric dibucaine in the left lateral positions. As soon as the patient was put into the supine position, he started to complain about severe lightning pain in the region of his hyposthesic segments. Severe lightning pain completely diminished 4 hours later when the effect of spinal anesthesia disappeared.
