A review of acute responses, after-effects and chronic complications related to microneurography

Microneurography, a technique used to detect postganglionic sympathetic nerve traffic in humans, is increasingly used to further the understanding of autonomic regulation in health and disease. The technique involves the transcutaneous insertion of a microelectrode into a peripheral nerve, following which, a variety of adverse acute responses; after-effect and chronic complications have been documented. Here, we comprehensively review the potential adverse outcomes of microneurography and provide updated quantifiable incidence rates of their occurrence within a general population. We also present recommendations for risk assessment and management of such outcomes, as well as recommendations to improve future reporting. This review aims to use objective evidence to improve the understanding of the rare, but present, adverse outcomes of microneurography.
