Two cases of subdural catheter placement following continuous spinal and continuous epidural anaesthesia are presented. In the first, despite an easy reflux of clear cerebrospinal fluid through the catheter, the injection of 4 ml bupivacaine 0.5 per cent with epinephrine 1:200,000 followed by 3 ml tetracaine 0.5 per cent showed a failure of spinal anesthesia. ⋯ The clinical signs observed in these two cases are compared with previous publications. The importance of an x-ray contrast study to confirm the diagnosis of subdural catheter insertion is stressed.

This five-year retrospective study reviews our experience with epidural obstetric analgesia in patients with previous Harrington rod instrumentation (HRI) for correction of idiopathic scoliosis. Patients were identified by the presence of an antepartum anaesthetic consultation for HRI. The anaesthetic record was examined to determine the frequency of epidural catheter insertion and any problems related to this procedure. ⋯ There were no sequelae related to epidural insertion. There were no sequelae related to epidural insertion. We conclude that patients with HRI may be offered epidural anaesthesia for labour and delivery provided that they are informed of the increased risk of complications.
