Capsaicin for post-surgical neuropathic peripheral pain –calculation of allodynia area Capsaicin 8% patch is indicated for the treatment of peripheral neuropathic pain in non-diabetic adults either alone or in combination with other medicinal products for pain. Thereis scarce information on results of capsaicin treatment for postsurgical neuropathicperipheral pain. Our aim is to correctly evaluate the area variation of the capsaicin patchbetween first and last treatment in patients with postsurgical neuropathic peripheral pain.Backgrounds e aimsMethodsIn order to compare patch areas of sequential treatments we manually calculated the areaof sequential patches. Recognizing the limits of this strategy we have implemented theuse of an application which allows area calculation from a photo of the patch.We selected patients with postsurgical neuropathic localized peripheral pain referred topain clinic between 2012 and 2015. We compared the area of capsaicin patches fromsequential treatments using SketchAndCalc ™ - Area Calculator. Descriptive statisticswere calculated with PSPP software.ResultsWe recruited 10 patients which completed the treatment in a mean of 4 sessions. Fromthe first to the last treatment there was a mean area reduction of 55,82cm2, SD of149,21cm2. The mean percentage modification of the last patch from the first one was25,4% with SD of 38,7%.ConclusionsAccurate calculation of patch area allowed precise documentation of therapeuticevolution. For capsaicin treatment this could allow crucial information for follow-up ofpatients.Sources: 1. Ther. Adv. Neurol. Disord. 6, 287–297 (2013)2.
