Patients with low-voltage electric shock referred to an Emergency Department.

BACKGROUND:Patients exposed to electricity are often referred to the Emergency Department, but guidelines differ as to how they should be managed. In this article, we describe patients with low-voltage electric shock in the Emergency Department at St Olav's Hospital, Trondheim University Hospital. MATERIAL AND METHOD:Retrospective data from patients referred to the Emergency Department following low-voltage electric shock (< 1,000 V) in the period 1.1.2012-31.12.2017 (N = 210) were included. RESULTS:The median age was 26 years and 186/210 (89 %) were men. Out of the 210 patients, 165 (79 %) had symptoms following electric shock. Localised pain and chest discomfort occurred in 84/165 (51 %) and 57/165 (35 %) of patients respectively. ECG findings were normal in 168/209 (80 %), and no patients had arrhythmias requiring treatment or elevated troponin T or creatine kinase. No patients had serious complications or died. INTERPRETATION:Low-voltage electric shock did not cause serious arrhythmias or elevated levels of troponin T or creatine kinase. It should be possible to manage asymptomatic patients with normal findings on clinical examination and ECG in a prehospital setting without reducing patient safety.
