Dingley2 1 Specialty Trainee 5, Department of Anaesthetics, University Hospital of Wales, Cardiff, UK 2 Reader and Consultant, Department of Anaesthetics, Swansea University College of Medicine, Swansea, UK Summary In 153 AD, the Roman physician Scribonius Largus identified that electric current had analgesic properties, instruct- ing patients to stand on an electric ray for the treatment of gout. In 2014, transcranial magnetic stimulation was approved by the National Institute for Health and Care Excellence for the treatment of migraine. Although separated by nearly two millennia, these milestones represent the evolution of the utilisation of electric current in medical and anaesthetic practice. Significant advances have been made over the last century in particular, and during the 1960s and 1970s, tens of thousands of patients were reportedly anaesthetised for surgical interventions using electric current as the anaesthetic agent. Many medical interventions, including transcutaneous electrical nerve stimulation and deep brain stimulation, have evolved in the aftermath of investigations into electroanaesthesia; the potential for electric current to be an anaesthetic agent of the future still exists. .................................................................................................................................................................
