The vexing question whether the acupuncture needle is as safe as most acupuncturists seem to believe has been raised several times before on this blog. Here is a new case-report by Japanese authors which sheds an interesting light on this issue.

A 62-year-old man was admitted to A+E complaining of dizziness and diaphoresis. He had received an acupuncture treatment in the sub-xyphoid area (lower 2 cm and left 1 cm point from the lower xyphoid process border) only about one hour ago. He had a history of cerebral infarction and atrial fibrillation, and the latter condition was treated with 2 mg warfarin per day. On admission, the acupuncture needle was still sticking in his sub-sternum.

His blood pressure was 80/50 mm Hg, and tachycardia with 110 beats/min was noted. The acupuncture-needle was duly removed, but the patient went into cardiac arrest and had to be resuscitated. Because his international normalized ratio was 1.99, 2 pints of fresh frozen plasma and 5 mg of vitamin K were administered at that stage. A transthoracic echocardiography revealed pericardial effusion with early diastolic collapse of the right ventricle. Emergency pericardiocentesis using a sub-costal approach was performed. After drainage of 500 mL of sanguineous effusion, the patient seemed to stabilize.

Two hours later, the drainage of pericardial effusion amounted to around 1000 mL, and cardiac arrest re-developed. After another resuscitation, an operation was performed under cardiopulmonary bypass (CPB). A median sternotomy allowed visualization of huge hematomas over the right atrium and ventricle. After the hematomas had been evacuated, pulsating blood loss from the marginal branch of the right coronary artery was identified. The vessel had been torn into pieces, and it was ligated which stopped the bleeding. Thereafter, the patient remained hemodynamically stable. Subsequently the patient made an uneventful recovery and, eventually, he was discharged without further complications.

The authors of this case-report conclude as follows: To our best knowledge, this appears to be the first case of an acupuncture-related coronary artery injury. The important causes of this unfortunate adverse event are a lack of anatomic knowledge and an incorrect application of the procedure. It can be avoided that acupuncture leads to cardiac tamponade like most serious complications….every acupuncturist should be aware of the possible and life-threatening adverse events and be adequately trained to prevent them.

In 2011, we published a review of all cases of cardiac tamponade after acupuncture. At the time, we found a total of 26 such incidences. In 14 patients, the complications were fatal. In most reports, there was little doubt about causality. We concluded that cardiac tamponade is a serious, often fatal complication after acupuncture. As it is theoretically avoidable, acupuncturists should be trained to minimize the risk.

Acupuncture-fans will, of course, claim (as before) that it is alarmist to go on about risks of acupuncture or alternative medicine which are so minute that they are dwarfed by those of conventional health care. And I will counter (as before) that it is never the absolute risk that counts, but that it is the risk benefit balance which defines the value of any therapeutic intervention. As long as we have no solid proof that acupuncture is more than a “theatrical placebo“, even a tiny risk weighs heavily and seems unacceptable.

But the true significance of this case-report lies elsewhere, in my view: risks of this nature can and should be avoided. The only way to achieve this aim is to train and educate acupuncturists properly. At present this does not seem to be the case, particularly in Asian countries where acupuncture is most popular. It is up to the acupuncture communities across the globe to get their act together.

2 Responses to Alternative practitioners’ lack of knowledge puts patients at risk: the example of acupuncture and cardiac tamponade

  • I think you could by now make a good case for all public funding or endorsement of acupuncture to be withdrawn and further trials and use permitted only under close medical supervision.

    Repeated trials by acupuncturists have the appearance of “keep asking until you get the answer you want”. It is pretty clear by now that acupuncture, as such, is nonsense, and the evidence for effect of needling (i.e. not rooted in silly notions of the body as a map of China) is pretty poor, while evidence of harm is specific and compelling, even if the events are relatively rare. This puts it in the same box as chiropractic: a fundamentally wrong philosophy with documented risks albeit with some weak evidence of an effect that merits investigation independent of believers.

    Acupuncture, as defined, is clearly fundamentally in error. The great tragedy of science is, as always, the slaying of a beautiful hypothesis by ugly fact.

    • In terms of commentary on or assistance with issues of the human condition, nothing there of any value whatsoever. Nada, rien, zilch. We can just move on without a backward glance.
