Spinal anesthesia is commonly used for cesarean section as it is safe and effective. However, subdural block can occur which might lead to loss of consciousness. We hereby report a parturient who received epidural analgesia for normal vaginal delivery followed by spinal anesthesia for emergency cesarean section and lost consciousness for 5 min after 10 min of spinal anesthesia induction.
