It is a general belief that in patients with spina bifida analgesia for labour and delivery can be associated with greater frequency of failure, accidental dural puncture and post-dural puncture headache (1,3,4) The use of continuous epidural, caudal and spinal analgesia, paravertebral sympathetic and paracervical blocks and intravenous patient-controlled analgesia have been reported in pregnant women with spina bifida; however, all of these techniques have been associated with a number of limitations (e.g., technical difficulty, excessive cranial/poor perineal spread of local anaesthetics and/or asymmetric block) and complications (e.g., dural puncture) (1,3,4).
