Purpose:
To present two successful cases of labour analgesia in patients who had been treated with radiation to the lumbar spine for neuroblastomas and to discuss the considerations when planning the anaesthetic management of these patients.
Clinical Features:
We recently encountered two primigravidas requesting labour analgesia, both of whom were noted to have very thin backs with prominent spinous processes and obvious scoliosis. In both patients, the epidural space was easily identified and very shallow. Successful labour analgesia was achieved in both patients, one with a combined spinal epidural technique and the other with an epidural catheter.
Conclusion:
Craniospinal irradiation is known to have long-term effects on exposed nervous tissue, bone, and blood vessels. While a larger experience is necessary to demonstrate safety of regional anaesthesia in parturients following previous spinal irradiation, we provide reports of two successful cases.
