Let’s get started with the Laws of Trauma!

After pursuing any discipline for an extended period, one begins to see the common threads and underlying principles of their area of expertise. I’ve been trying to crystallize these for years, and today I’m going to share one of the most basic laws of trauma care.

The First Law of Trauma

Any anomaly in your trauma patient is due to trauma, no matter how unlikely it may seem.

Some examples:

• An elderly patient who crashes his car and presents with arrhythmia and chest pain is not having a heart attack. Nor does he need a cardiologist or a trip to the cath lab. It is far more likely the crash is causing these problems rather than an MI causing a crash.
• A spot in the liver after blunt trauma is not a cyst or hemangioma; it is a laceration until proven otherwise.
• A patient found at the bottom of a flight of stairs with blood in their head did not have a stroke and then fall down.
• A patient who follows up in your trauma clinic with new complaints after a previous gunshot to the abdomen needs further clinical investigation, not just reassurance.

Bottom line: The possibility of trauma always comes first! It is your job to rule it out. Injury can and does kill people more quickly that an MI or a stroke, especially if it was never suspected.

Only consider non-traumatic problems as a last resort. Don’t let your non-trauma colleagues try to steer you down the wrong path, only to have your patient suffer.

I’m going to be (re)sharing the laws of trauma over the next few posts. I’ve identified a total of eleven over the past 12 years, and I wanted to share them with you.

But first, I’d like to share another trauma surgeon’s observations. Dr. Norman McSwain was an icon in trauma surgery during the early years of my career.

I knew Norm for decades and literally grew up reading about his advancements and accomplishments. Unfortunately, he passed nine years ago. It’s interesting that one never truly appreciates the magnitude of a colleague’s achievements until the person is gone.

Norm was a skilled surgeon and teacher, but his achievements were felt far outside his home in Louisiana. He was an early member of the ACS Committee on Trauma, and was very involved in the development of the Advanced Trauma Life Support and Prehospital Trauma Life Support courses. He is credited with developing the original EMS programs in both Kansas, where he took his first faculty position out of residency, and in New Orleans, his home for the remainder of his life. He spent his career at the Charity Hospital there, weathering multiple political storms over the years, as well as the big one, Hurricane Katrina. He was instrumental in achieving Level I Trauma Center status for its replacement, Interim LSU Hospital.

Norm’s accomplishments are, as many of his contemporaries who have left us, too numerous to count. I certainly won’t try to recount them here. But it was his charm, his love for his charges, and his willingness to teach every trauma professional that will always be remembered.

I’ll leave you with his 18 rules of patient care. They are timeless and will serve you well regardless of your degree and level of medical training.

In my next post, I’ll start explaining the eleven laws that I’ve developed.

Here’s the last one… for now.

If you have followed this blog for any period of time, you are aware of the skepticism I bring to bear when I am reading new material or learning of new ideas. Why is this? Because it is very difficult in this day and age to ascertain the veracity of anything we see, hear, or read.

This is not new compared to, say, a hundred years ago. The media were a bit different, but the underlying issues were the same. There have always been two major factors at play: information overload and the biases built into our human brain operating system.

There is a huge body of new information in every field that is being produced every year. Given the pressures that most researchers are under to publish or perish, a huge number of papers are sent to journals for review. Unfortunately, this leads to a huge number of publications that are of lower quality.

This also contributes to another recognized phenomenon, the half-life of facts. Think about all the things you learned during your training that are no longer believed to be true. Stress causes ulcers. Steroids are good in head injury. There is a definite decay curve for the old facts that occurs as new knowledge is acquired.

So we have a huge amount of potential junk to sort through to figure out what cellular mechanisms are correct or which medications work for a disease. And then we run into our own operating system problems.

All humans have our own innate beliefs that are shaped by experience and all the information we’ve consumed over the years. And we are genetically programmed to do this:
Learn something new  —>  believe it  —>  verify it

And many of us never get to the verify stage because another operating system issue, confirmation bias, takes over. If we learn something that confirms an existing belief, we are much more likely to believe and much less likely to verify. If we learn something that opposes our belief, we still want to believe what we already do and find every flaw in the new data that might refute it.

So here is my eleventh law of trauma:

“Don’t believe anything you learn, especially if it supports what you already believe”

Bottom line: If you read or hear something new, first examine the source. Is it legitimate and reliable? Where did it get the info? Then check out that source. Critically evaluate it, even if it already supports what you believe. Always treat new information, especially if you think it’s right, as an opportunity to learn something new. Sometimes you will find real gems in the things you thought were wrong, and real crap in the things you believed to be right!

It’s time to flip the algorithm to:
Learn something new  —>  verify it  —>  believe it

Several years ago, I ran a series of posts on my Laws of Trauma. I assembled them into  newsletter that contained all nine that existed at the time. If you’d like to download it, just click this link.

I’ve  been struck by another pattern, and I think it’s about time to add the tenth law. Weirdly enough, it was inspired by Dancing With The Stars. You’ll see what I mean.

Here is the Tenth Law of Trauma:

In trauma, it generally takes two to tango

So what does this mean? When dealing with injury, there are a few broad quantitative categories.

• Single person mechanism. This is one extreme. Common examples would be the elderly fall, a single vehicle car crash, or a self-inflicted stab or gunshot. There is a single “point of failure” that only the individual involved can manage, but for various reasons they do not or cannot. This law does not apply.
• Multiple person mechanism. This is the other extreme, and thankfully is not seen very often at all. Examples are a tour bus crash, house explosion, or mass casualty event. Once again, those involved usually have little ability to recognize or avoid the imminent event, and the tenth law is null and void.
• Two person mechanism. This one is very common, and is exemplified by the two car crash, pedestrian struck, or the various flavors of assault. And this is the one that the tenth law applies to.

When two people are involved in an event that leads to traumatic injury, there is usually (but certainly not always) a set of checks and balances that is present. And frequently there is at least one opportunity to avoid the event.

In the case of a two vehicle crash, one driver may have “gone off the deep end” and ignored the usual traffic laws for whatever reason. But the second driver usually has an opportunity to recognize this and change their behavior in order to avoid the situation. However, if they are distracted, impaired, or making assumptions about how other driver behave they can still get into trouble. Thus, it takes two.

What about the pedestrian struck? Likewise, the driver or the pedestrian may have done something nonstandard. Wear dark clothes at night. Glance at their phone while driving. Look at their passenger a bit too long while having a conversation. Once again, the other participant may have an opportunity to see the result of this unexpected behavior and jump or swerve out of the way.

Interpersonal violence it a bit more tricky. Sure, one of the potential participants may get wind that something is up and try to avoid or defuse the situation. But not always. And this situation is heavily charged with emotion and social pressures and is much more difficult to change or avoid.

Bottom line: Many, but certainly not all,  “two-person” mechanisms of injury are avoidable if both of the individuals involved are mentally present and attentive to their surroundings. Look at your own patient population and see how often this applies. You may be surprised!

Okay, here’s another one! But it’s a doozy. It’s the most important one I live by. It ensures that you don’t get bogged down by habit, custom, dogma, ignorance, or just plain laziness.

Question everything!

If someone ever says, “but that’s the way I/we always do it,” or “that’s what the policy says,” or even “I read a good paper/chapter on this,” take it with a really big grain of salt. Or a salt lick (if you know what that is; otherwise look it up).

And here’s a corollary:

Don’t believe everything you think!

Consider that one for a minute.

Bottom line: It’s up to you to decide what is right for your patients. Others may not have done the leg-work and may not be as knowledgeable as you think. Always check the facts!
