Storm, CPR, and the Precordial Thump

July 15th, 2009

Filed under: Comics, Medicine

Storm’s CPR technique starts off looking quite good. Her rescue breathing appears fine, and her hand position — and correctly interlocked fingers — are impeccable.

However, when the traditional CPR doesn’t work, she reaches back and gives Cyclops a hard thump on his chest.

And that’s the problem.

The precordial thump is an actual medical technique — but it is only used in very limited circumstances. Consider how the precordial thump works: it doesn’t restart the heart or help circulate blood through the body, but instead works by interrupting dangerous heart rhythms such as ventricular fibrillation. The thump is only supposed to be used if the patient had a witnessed cardiac arrest (the rescuer actually saw the arrest occur), and only at the very beginning of resuscitation. Only one blow should be tried. The precordial thump has a small, but real, success rate (it depends on your source, but positive results are — at best — 25%). If it fails, the rescuer then proceeds with normal CPR.

By the time Storm gets around to performing the thump on Cyclops, it is too late for it to have any effect. She’s also being overly aggressive in her technique, and is likely to injure Cyclops along the way.

Personally, I’ve only used the precordial thump once. I was an intern, and it was my first night on call in the ICU. I was called to examine a patient who had been having a decreasing blood pressure. When I arrived, he was lying in bed and he looked a little pale, but was responsive. Suddenly, he collapsed and when I looked up at his heart monitor, I saw new onset torsades de pointe. Without thinking, I reached out and thunked him in the chest. His rhythm returned to normal and he came to. I called the attending ICU physician and ordered some magnesium sulfate. About thirty seconds later, the patient slipped into torsades again.

“Thump him!” I screamed at the nurse (let me assure you, I was not screaming in anger; more likely it was panic). She did, and once again his rhythm was restored to normal.

Both the attending and the medication took their sweet time to arrive and by the time they showed up in the room, we’d had to thump him two more times. Luckily, the magnesium sulfate worked and his torsades never recurred.

    Still, at least she doesn’t do the obvious thing, given Storm and her powers, and shock the flatline, right? :-P

    The Percordial Thump is a wonderful name for a medical procedure. It’s just a shame that the the artist didn’t grace the scene with the appropriate sound-effect.

    One of the medicine chiefs the year ahead of me in residency was legendary for this. The story went that he was just passing through the ICU one day when he passed a guy just at the moment he went into VFib. He apparently hauled off and thumped him with a big overhand punch and stopped the rhythm.

    don’t be offended, but when reading your anecdote, all I could think of was the dream sequence in [Scrubs] where JD imagines that he is Fonzie waking a comatose patient with the lesser known Jukebox Thump.

    If you’re going to bring up Scrubs, you can’t ignore The Todd’s “Miracle Five”…

    I guess that, in some ways, the precordial thump just resonates with people. Unlike things like CPR which require extensive training and following strict procedures, the thump seems like a primal expression of “Live, goddamit!” where we personally storm the gates of death through our sheer desire to save the victim. And it fits with our mental picture. When you hit someone, they bolt upright and gasp. Chest compressions just don’t conjure up the right image.

    Maybe I’ve been out of the comic seen too long. When did Storm become orange? Why are we not addressing this House-style medical mystery?

    My mum recounts a story from the Dark Ages of medicine, when defibrilators where the size of small cars. Patient kept going into Vfib, but was a long way from surgery – so they ended up wheeling them through the corridors of the hospital, past patients and visitors, with my mum thwacking him on the chest every few minutes every time he went into VFib. So she’s done it dozens of times :)

    It would be nice to read more of your very interesting med stories; the “True Tales of Medical School” section is rather lonesome for lack of updates : (

    I swear I saw “Bones” McCoy do it to a Kingon in one of the Star Trek movies.. (VI?). I don’t think he did it right either.

    Yeah, six, after the Chancellor got shot. He played with his gizmos, realized that he was going into come kind of arrest, then thumped him. Not sure if any CPR was used…
