Case Reports
Caudal blockade in the management of aortic thrombosis following umbilical artery catheterisation.
A neonate, with a postconceptual age of 29 weeks, suffered thrombosis of the aorta as a consequence of umbilical artery catheterisation. This resulted in ischaemic lesions of the lower limbs and buttocks. Part of the management consisted of the insertion of an extradural catheter, via the caudal route, which provided good pain relief and may have improved lower limb blood flow.

We present our experience with a new combined spinal epidural system through which regional anaesthesia was performed in 30 male patients undergoing suprapubic prostatectomy. The technique consists of two needles, a 17 G Tuohy needle with a hole in its distal curve (back eye) and a 29 G spinal needle which is passed through the back eye before being introduced into the subarachnoid space. We found the back eye combined spinal-epidural system effective and simple to use. The Tuohy needle with its back eye did not impede insertion of the epidural catheter and was a suitable introducer for the thin 29 G spinal needle.
