Neurologic and neuropsychological symptoms during the first year after an electric shock: results of a prospective multicenter study
Abstract
OBJECTIVES: To assess the prevalence of neurologic and neuropsychological symptoms in the short-term and 1 year after an electric shock and to explore whether any of these were associated with risk factors.
METHODS: Patients presenting to one of 21 EDs between October 2000 and November 2004 were eligible to be enrolled in a prospective observational study after an electric shock if they had risk factors for late arrhythmias. Telephone follow-up was done to evaluate the appearance of symptoms.
RESULTS: A total of 30 (26%) of 114 patients complained of neurologic or neuropsychological symptoms at a median of 52 days post-electric shock. At 1 year, 24 (28%) of 86 patients complained of neurologic or neuropsychological symptoms. None of the risk factors evaluated were associated with the symptoms.
CONCLUSION: The prevalence of the symptoms we observed should alarm all emergency physicians that the effect of electricity can cause late neurologic and neuropsychological manifestations.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 114 participants or records.
