Title:	A prototype axial ultrasound needle guide to reduce epidural bone contact
Authors:	Chen, GS;Chang, YC;Chang, Y;Cheng, JS
Contributors:	Division of Medical Engineering Research
Abstract:	We have developed an ultrasound probe through the centre of which an epidural needle can pass, intended to reduce the rate of contact between bone and needle during epidural insertion. We tested the ability of this probe to identify the lumbar interspace, using A-mode ultrasound, in a submerged plastic model, a porcine phantom and five human volunteers. In the plastic model, the minimum echo representing the interspace was only 8.8% of the maximum echo from the 'bone'. In the porcine model, the echo variations between the interspace and L3 were up to 48% and the needle was safely inserted into the interspace without bone contact under guidance. The human study also showed that the maximum bone echo was at least three times stronger than the interspace echo. Axial ultrasound guidance, with the needle passing through the probe, offers a method for reducing bone contact during epidural insertion.
