- Orthopaedic surgeons have to be 100% positive they are replacing the right, er, I mean the correct hip
- Urologists have to be 100% positive they are removing the correct (ahem) testicle
- Surgical oncologists have to be 100% positive they are removing the mass from the correct breast
Ok, that's not entirely true and I'm exaggerating slightly. But only slightly. I should clarify that as long as the surgery is indicated, the surgeon will never be considered wrong, even if there's nothing actually wrong. After all I can't justify cutting open someone's abdomen if he's been shot in the foot, for example. However, a patient who arrives in my trauma bay in profound shock and actively dying without an obvious source (ie blood pouring out of his neck) may be justifiably taken for immediate chest and/or abdominal surgery if there is a strong enough suspicion that there is something in one of those cavities that is causing imminent death.
Of course I need to do everything I can to ensure that the surgery is actually indicated, but sometimes there isn't time to verify. And even if I'm wrong and the problem was elsewhere (sepsis unrelated to the car accident, for example), that is a risk I have to take in order to potentially save his life. I don't have be completely 100% sure, I don't have to be right, I just have to be pretty damned sure.
I hope that makes sense now.
That being said, I love being sure, I hate being wrong, and I love being right. And that was most definitely 100% the case with Trent (not his real name™).
I was in the middle of reading a scintillating article on the treatment of pancreatic cancer (ZZZZZZzzzzzzzzzzzzzzzzzzzZZZZZZZZ) when my pager alerted me to a level 1 stabbing victim arriving in 10 minutes. I looked at my watch and nearly gasped - it was just after 2 PM. Getting a stabbing victim in the middle of the day is a bit of a luxury. Operating in the middle of the day rather than the dead of night? It's almost like a vacation! I casually tossed (read: aggressively threw) the fascinating (boring as hell) journal aside and ran down to the trauma bay, excited to get a serious trauma while the sun was shining. Five minutes later I met Trent, though I can't really say that Trent met me, because he was nearly unconscious. He was moaning and could barely open his eyes.
"Hey Doc, this is Trent. He's young, maybe 25 or so, single stab wound to the chest."
They had already disrobed him, and despite the cool weather, Trent was sweating profusely. UH OH, my Inner Pessimist groaned. A quick survey of both his front and back (never forget to look at the back!) informed me that the medics hit the nail right on the head - one solitary stab wound just to the right of the sternum (breast bone). I whipped out my handy dandy, um, heart-listening doohicky thingy . . . you know, that thing that goes in your ears that surgeons rarely use . . . whatever. Anyway, his heart was beating, but for such a young guy it didn't sound very loud. His breath sounds were normal and equal on both sides, so I doubted he had a serious lung injury. His heart, on the other hand . . .
A stab wound to this location can go pretty much anywhere and hit pretty much anything - right chest, left chest, abdomen, mediastinum (which contains the heart) - but I strongly suspected my Inner Pessimist (who was screaming "IT GOT HIS HEART, DUMBASS! IT GOT HIS HEART!!" repeatedly) was right. I just wanted to be sure before I slashed open his chest. Or at least pretty damned sure.
While the radiology techs shot a chest X-ray (which was normal, no sign of a pneumothorax), I ran over to get my ultrasound machine. A sonogram in trauma takes less than a minute and is designed to do one thing: detect fluid where it does not belong, either in the chest or in the abdomen. I listened to my Inner Pessimist (who was still screaming something about the heart directly in my ear) and put the probe on his epigastrium just under his breastbone first, aiming up at his heart. Despite doing trauma for {redacted} years, I have still seen very few positive trans-thoracic echocardiagrams, because these folks usually die before reaching me. This study looked . . . hm, weirdly positive, I thought. It looked like there was fluid within the pericardium, the sac that surrounds the heart. In an elderly person with congestive heart failure this could be considered normal, but in a normal healthy young guy with a stab wound to the chest, it always means a hole in the heart. Well, almost always. Pretty much. But having seen so few positive studies, I still wasn't 100% sure.
Knowing I didn't have to be 100% sure (but still wanting to be), I completed the sonogram of his abdomen (which took about 45 seconds) and saw no fluid around his liver, kidneys, spleen, or pelvis. ("THE HEART! THE HEART!"). Just to be the tiniest bit surer I went back up to his chest, and again there was that thin line of black (fluid) around his heart where only white (tissue) should be.
I was now absolutely positively at least 95% pretty sure that the knife had pierced at least the pericardium, if not the heart itself. That was more than enough for me and Trent.
About 15 minutes later we were in the operating theatre, and on the way I explained to him that I was going to open his chest and repair his heart. I am unsure if he heard most of what I said, and I'm even less sure that he understood any of it. As he was put under anaesthesia, I did the one thing I had been wanting to do since he arrived: I put my finger into the stab wound. Gently. For me this is the most accurate method of demonstrating that a knife (or gunshot) wound penetrates into some cavity where it should not have been. I felt my finger slide between two of his ribs (one of which had been fractured by the knife), and the tip of my finger nestled right onto something that was beating, moving rhythmically at exactly the same pace as the monitor was beeping.
My "95% sure" was now 100%.
Five minutes later his sternum was split in half. I opened his pericardium, and there to greet me was a 2 cm laceration in his right ventricle.
In case you hadn't guessed, that's considered a Very Bad Thing.
The key in this situation is to stop the bleeding. Initially, this is very easy to do - I stuck my finger over the wound to plug it. This allowed the anaesthesiologist time to catch up with resuscitating him, and it allowed the nurses time to get the supplies I needed to fix it definitively. It only took about 15 minutes to suture the laceration, 5 minutes to look around the rest of the chest to confirm that there weren't any other injuries (there weren't), and about 30 minutes to close. In all, it took about 75 minutes from the time he hit the trauma bay door until he was in the recovery room.
And only four days for him to walk out of the hospital.
Over those four days, unlike most of my patients Trent was extremely appreciative of our work to save his life. He made every effort to say "Thank you", or "I really appreciate you", at every opportunity. Trent even made it clear that he needed to shake my hand whenever I left the room. I always make a conscious effort to treat all my patients equally no matter what, so while his appreciation did make taking care of him that much easier, I am absolutely positive that I did not treat him any differently than anyone else.
Well, pretty sure.
Wow, I've always wondered how you go about fixing a hole in the myocardium... do you just stitch it really well or do you have to use something else? I would be afraid of the stitches being pulled apart by the ventricle when it's beating.
ReplyDeleteVery carefully, with non-absorbable sutures and pledgets.
DeleteYou suture a ventricle while the heart's still beating? That must take some practice!
DeleteGood work as ever Doc'.
Ugi
Yes indeed. It can be harrowing, but it's manageable. The idea is to throw the suture between beats, or something like that.
DeleteA perfect candidate for rescucitative thoracotomy.
ReplyDeleteI suspect I know who this anonymous commenter is, but just in case I'm wrong -
DeleteThis was neither resuscitative nor a thoracotomy. It was an exploratory followed by therapeutic sternotomy. And in case you meant that I *should* have done a resuscitative thoracotomy, that procedure was not indicated as he was not dead or imminently dying.
The thoracotomy approach is always superior to median sternotomy especially with cardiac tamponade.
DeleteI don't know. I've always found the competency approach superior to the googlfication approach.
DeleteThat at least confirms my suspicion about the commenter.
DeleteYou'll find, John, that sternotomy is the preferred approach especially for right ventricle injuries. Or at least, you'd find that had you attended medical school and cardiac surgery training. Please do so, then come back and apologise. We all look toward to hearing back from you in 12-15 years.
did you remember to recommend that he buy a lottery ticket?
ReplyDeleteActually, yes.
DeleteDo we know how he got stabbed in the heart in the middle of the afternoon?
ReplyDeleteNope. I wasn't interested. I rarely get satisfactory answers to such questions, so I rarely ask.
DeleteEerily, there was an attacker that stabbed several people on the campus at Ohio State University on the day this was published. I doubt Trent was one of those, but kids were getting stabbed (and hut by a car) at 10am by going to class.
Delete" I did the one thing I had been wanting to do since he arrived: I put my finger into the stab wound. " This made me smile.
