If we listen to acupuncturists and their supporters, we might get the impression that acupuncture is totally devoid of risk. Readers of this blog will know that this is not quite true. A recent case report is a further reminder that acupuncture can cause serious complications; in extreme cases it can even kill.
A male patient in his late forties died right after an acupuncture treatment. A medico-legal autopsy disclosed severe haemorrhaging around the right vagus nerve in the neck. All other organs were normal, and laboratory findings revealed nothing significant. Thus, the authors of this case-report concluded that the man most probably died from severe vagal bradycardia and/or arrhythmia resulting from vagus nerve stimulation following acupuncture: To the best of our knowledge, this is the first report of a death due to vagus nerve injury after acupuncture.
In total, around 100 deaths have been reported after acupuncture in the medical literature. ‘This is a negligible small figure’ claim acupuncture fans. True, it is a small number, but it could just be the tip of a much larger ice-berg: there is no reporting system that could possibly pick up severe complications, and in the absence of such a scheme, nobody can name reliable incidence rates. And even if the numbers of severe complications and deaths are small – even a single fatality would seem one too many.
The deaths that are currently on record are mostly due to bilateral pneumothorax or cardiac tamponade. The present case of vagus nerve injury seems to be ‘a first’. Perhaps we should watch out for similar events?
IF WE DON’T LOOK, WE DON’T SEE.
