BACKGROUND: Many sufferers with persistent idiopathic axonal polyneuropathy (CIAP) undergo from neuropathic ache, which is managed utilizing a number of oral drugs and modalities. Nevertheless, regardless of these remedies, ache persists in some sufferers.
OBJECTIVE: Within the scientific area, clinicians regularly meet sufferers with neuropathic ache attributable to CIAP. The authors investigated the impact of caudal epidural pulsed radiofrequency (PRF) for the administration of CIAP-induced refractory neuropathic ache.
STUDY DESIGN: It is a potential research.
SETTING: The outpatient clinic of a single educational medical middle in KoreaMETHODS: Twenty sufferers with neuropathic ache and a analysis of refractory CIAP have been recruited. For PRF stimulation, a 22-gauge cannula was inserted into the epidural house via the sacral hiatus underneath fluoroscopic steering. PRF stimulation was administered as soon as at 5 Hz with a 5-ms pulse width for 600 seconds at 55 V. The impact of stimulation was evaluated utilizing a numeric score scale (NRS) at 2 weeks and 1, 2, and three months after the process. Profitable ache reduction was outlined as a discount within the NRS rating of>/= 50% as in contrast with the rating previous to therapy. As well as, at three months after therapy, affected person satisfaction ranges have been examined; sufferers that reported “superb” (rating = 7) or “good” (rating = 6) outcomes have been thought-about to be happy with the process.
RESULTS: Neuropathic ache was considerably lowered at 2 weeks and at 1, 2, and three months follow-up after PRF (P < zero.001, repeated measures one-factor evaluation). As well as, at three months post-PRF, half of the sufferers achieved a profitable response (>/= 50% ache discount) and have been happy with therapy outcomes.
LIMITATIONS: A small variety of sufferers have been recruited, and we didn’t carry out long-term follow-up.
CONCLUSION: Caudal epidural PRF could also be a superb therapy choice for managing neuropathic ache induced by CIAP, particularly when ache is unresponsive to oral drugs.
