title: Obstetric epidural anaesthesia in patients with Harrington instrumentation.
abstract: 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. Nine epidural insertions were attempted in the 16 patients identified. Five were uncomplicated but four were complicated by one or more of: failure to identify the epidural space, blood vessel trauma, dural puncture, failure to obtain analgesia or the need for multiple attempts before successful insertion. 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.
