Randomized Controlled Trial Clinical Trial
Evaluation of a spinal needle locking device for use with the combined spinal epidural technique.
Success of the 'needle-through-needle' technique for combined spinal epidural analgesia requires the immobilisation of the spinal needle during intrathecal injection. A device that achieves this was evaluated in 200 labouring women, randomly allocated to receive a combined spinal epidural using the CSEcure(R) (SIMS Portex, UK) locking needle or a conventional, non-locking technique. ⋯ Although not statistically significant, there was a higher number of technical failures, mainly due to spinal needle movement, in the non-locking group (9.1 vs. 3.1%; p = 0.08). The locking needle device may be a useful alternative to conventional methods for combined spinal epidural analgesia.
