Currently, the neuromodulation community ascribes to the American Society of Regional Anesthesia and Pain Medicine guidelines, which state that nonsteroidal anti-inflammatory drugs do not significantly increase the risk for epidural hematoma with neuraxial anesthesia and, therefore, there is no need to discontinue these drugs before epidural or spinal anesthesia. We suggest that these guidelines may not be appropriate for neuromodulatory techniques that likely subject the surrounding vasculature to more trauma than neuraxial anesthesia. We recommend discontinuing nonsteroidal anti-inflammatory drugs, particularly aspirin, before neuromodulation procedures. Further investigation will establish a timeframe for holding these drugs to optimize patient safety.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
