[Meralgia paresthetica after spinal anesthesia].
A 27-year-old man underwent appendectomy under spinal anesthesia with 0.3% dibucaine 2.7 ml. The perioperative course was uneventful. The surgical procedure, however, lasted for 1.5 hours in the supine position. On the second postoperative day, a postspinal headache occurred and lasted for 18 days. On the seventh postoperative day the patient complained of numbness along the anterolateral aspect of the left thigh innervated by the lateral cutaneous nerve. There was no reflex or motor deficit indicative of the involvement of other nerves. The disorder was diagnosed as meralgia paresthetica caused by the surgical procedures. The numbness disappeared after the oral administration of mecobalamin in several days. In the treatment of a case like this, it is important to exclude neurological complications caused by spinal anesthesia.
