And then you have times like with Clancy (not his real name™) when I go from A to B to C to Q.
My mind was made up when I heard the Box announce Clancy's injuries about 15 minutes before he arrived - this guy was going to be fine I decided before even meeting him. He was stabbed in the thigh, which is typically not a severe injury. The blood supply to the leg is in the groin, and the thigh is a surprisingly large place, so getting stabbed in it anywhere other than the groin is very rarely a huge problem. However, having done this for {redacted} years, I know that I can only trust about 10% of what I hear over the Box, so a penetrating injury to the thigh is always treated as a high level trauma.
And then Clancy arrived and proved it. It turns out that "side" sounds a lot like "thigh" over the Box.
"Hi everyone, this is Clancy, 23 years old. He was stabbed once in the left side with a steak knife. He isn't sure how deep it went."
Clancy was a rather large chap, in the same way Jaws was a rather large fish. He weighed in at just under 150 kg (330 pounds), and was indeed stabbed once in the left flank right where his spleen, kidney, and colon should be living. God damn it. And unfortunately none of those organs particularly enjoys having holes poked in it.
My first step in any case like this is to determine how deep the wound goes and in what direction. So my initial move is to stick my finger in the hole (mind out of the gutter, people). This is by no means a perfect tool, because my finger may not be able to find the knife tract, and a thin blade can penetrate deeper than my fingertip will allow. However, I've found exactly nothing that can be as quickly diagnostic as a Finger In A Hole. And before I say anything else, I know exactly what that sounds like, and I absolutely stand by that statement 100%. Anyway, just by looking at a stab wound I can't tell what direction or how deep the knife went. A Finger In A Hole can quickly answer both questions.
He groaned slightly as my finger went in (STOP SNICKERING, DAMN IT!). And in. And in. As I said, Clancy was a large fellow. Fortunately (or unfortunately, depending on how you look at it), the knife tract was rather wide so it was easy to follow downwards towards his abdomen (not upwards towards his chest), and anteriorly towards his innards (not posteriorly towards, well, nothing vital). I could feel my finger going through fat and more fat and then . . . space. My fingertip slipped into his peritoneal cavity, and my mood sank.
Sigh. Straight to the operating theatre.
The general teaching is that anyone with a penetrating injury to the abdomen with clear violation of the peritoneum (the lining that contains all of the intra-abdominal organs) needs immediate exploratory surgery. No other tests are necessary, because if the knife went through that final layer, it most probably poked a hole in something in there. I immediately called out to the waiting operating staff standing by the door that we would be coming down in 5 minutes.
I explained all of this to Clancy, including the fact that something, everything, or nothing may be injured. He looked shocked but surprisingly understanding. I looked up at the monitor to see how fast his heart was beating.
65.
Uh, hm. As my son would say, well that was unexpected. People with major intra-abdominal injuries usually have significantly elevated heart rates, and their blood pressure can be low depending on how sick they are. I pushed on his belly and got nothing. No pain whatsoever. But since he was so obese, maybe I just wasn't pushing hard enough. I tried again, this time mashing on his belly. Nope, still nothing.
Hmmm. My mind seemed to be changing.
After contemplating for a moment, I decided to change my operative plan to a diagnostic laparoscopy - putting a camera in through a very tiny incision in his umbilicus and looking at all of the organs to assess for damage. If blood, bile, stool, or gastric contents are found, the procedure is quickly converted to a major laparotomy, and any damage is repaired. However, if there is no blood, no food leaking out of the stomach, and no poop leaking out of the intestine, then no major exploratory surgery needs to be done and the patient is saved a huge (and unnecessary) operation.
I went back and explained this to Clancy, and he seemed slightly relieved and still understanding despite the drastic change of plan. I called the theatre staff and told them of the change, and as I did so I looked at Clancy's monitor again. His heart rate was now 62, his blood pressure was 127/65 (probably better than mine at the time), and he looked completely comfortable.
Mind. Changing. Again.
Because he was so rock stable, I then decided to do a CT scan of his abdomen on the way to the operating theatre. It could at least guide me as to where I needed to place the camera first. Five minutes later I was looking at his scans as they flashed on the computer screen, and I was shocked - I could see exactly where the knife had penetrated into his abdomen, but it only went in about 2 mm. There was a very nice (and very clear) 1 cm layer of fat between the furthest extent of the stab wound and the closest organ (the descending colon). No blood, no air, no fluid, nothing. The radiologist actually read the scan as normal and missed the stab wound.
And my mind changed yet again. A to B to C to Q.
I somewhat abashedly approached Clancy yet again and told him the good news, that he probably did not need any surgery at all. Considering how many times I had changed my mind in the past 20 minutes, he took the news quite well. Just in case the CT was wrong, I decided to keep him in the hospital overnight and re-examine his belly every hour or so to make sure nothing was brewing. And 10 hours (and 10 re-examinations) later, I sent Clancy home with no new scars (except perhaps mental ones).
We often say in surgery that the enemy of good is better. Trying to get something from good to perfect often leads to complications, so we usually leave well enough alone. Being decisive is usually good, but additional information can actually be better. Sometimes.
After I wrote this post and read it back, I realised that it could potentially make me seem wishy-washy or irresolute, so I decided to delete it rather than publish it.
But then I figured "Ah, fuck it", and I changed my mind.
