title: Accidental total spinal block: a complication of an epidural test dose.
abstract: A case is presented of a 36-yr-old parturient who developed a total spinal block after an epidural test dose. After placement of an epidural catheter and confirming negative aspiration for blood or CSF, 3 ml lidocaine 1.5% (45 mg), with 1:200,000 epinephrine (15 micrograms) was injected via the catheter over 30 sec. Within two minutes the patient developed hypotension and extensive sensory and motor block including respiratory paralysis and aphonia. She remained fully conscious and alert and spontaneous respiration recommenced in five minutes. A live healthy infant was delivered by emergency Caesarean section shortly afterwards under general anaesthesia and the mother recovered completely without any untoward sequelae.
