The Trauma Professional’s Blog Is 5 Years Old!

I know, it’s hard to believe, but this blog turns 5 years old today! 

It’s been so much fun to see my readership grow over the past years. I’m so thankful to my thousands of readers all over the world. I’m also grateful for all the questions that I get from trainees and trauma professionals everywhere. It keeps me on my toes and keeps me reading and learning every day.

In the coming year, I will continue to try to provide answers to those pesky questions that you really can’t find anywhere else. I’ll also continue to try to digest stuff for you that is in the literature and give you my take on it, as well as whether I think it’s important or just plain bogus.

So THANK YOU very much, and have a fantastic new year. Keep those questions coming so I’ve got plenty to write about in the coming year.

Is This A Good Chest Tube?

A patient is transferred to your facility who had, as one of his problems, a sizable pneumothorax. A chest drain was placed at an outside facility prior to transfer. It is now 2 hours later, and as you finish evaluating him, you get the following x-ray.

What’s the problem here? How do you fix it? Tweet, email, or leave comments with your answers. Discussion and final answer on Friday!

Off-Label Foley Use – Part 2

Yesterday, I wrote about an unusual way to use the Foley urinary catheter to plug a heart wound. This allows you to buy time to get to the operating room to perform the definitive repair. But this cheap and effective tool is very versatile, and can be used in other body areas as well.

Consider a deep penetrating injury to the liver. It takes time to determine which method for slowing/stopping the bleeding is most appropriate. Sure, the doctor books say to occlude the inflow by gently clamping the hepatoduodenal ligament (Pringle maneuver). But this takes time, and can be difficult if there is lots of bleeding. 

You may be able to gain some time by placing a properly sized Foley catheter directly into the wound and carefully inflating with saline. You must inflate the balloon to feel, not to its full volume. It should be snug, but not so full that it cracks the liver parenchyma and causes yet more bleeding.

Bottom line: Any time you find yourself facing bleeding from hard to expose places, think about using a balloon catheter like the Foley. Sizing is critical, and the balloon volume is more important than the catheter diameter. Estimate the size of the area that needs to be occluded, and then ask for a catheter with a 10cc or 30cc balloon. If you need smaller, more precise control, try a Fogarty arterial embolectomy catheter instead. 

As with the cardiac Foley, be sure to occlude the end so you don’t create a conduit for the blood to escape. If your patient does well, and you need to leave the catheter in place for a damage control closure, LEAVE THE CATHETER COMPLETELY WITHIN THE ABDOMEN. If you exteriorize the end, some well-meaning person may unclamp it, drop the balloon, or decide that it can be used for tube feedings.

TIP: If the distance between the balloon and the catheter tip is too long, DO NOT TRY TO SHORTEN THE TIP BY CUTTING IT! This will damage the balloon and it will not inflate.

Off-Label Use of the Foley (Urinary) Catheter

Foley catheters are a mainstay of medical care in patients who need control or measurement of urine output. Leave it to trauma surgeons to find warped, new ways to use them!

Use of these catheters to tamponade penetrating cardiac injuries has been recognized for decades (see picture, 2 holes!). Less well appreciated is their use to stop bleeding from other penetrating wounds.

Foley catheters can be inserted into just about any small penetrating wound with bleeding that does not respond to direct pressure. (Remember, direct pressure is applied by one or two fingers only, with no flat dressings underneath to diffuse the pressure). Arterial bleeding, venous bleeding or both can be controlled with this technique. 

In general, the largest catheter with the largest possible balloon should be selected. It is then inserted directly into the wound until the entire balloon is inside the body. Inflate the balloon using saline until firm resistance is encounted, and the bleeding hopefully stops. Important: be sure to clamp the end of the catheter so the bleeding doesn’t find the easy way out!

Use of catheter tamponade buys some time, but these patients need to be in the OR. In general, once other life threatening issues are dealt with in the resuscitation room, the patient should be moved directly to the operating room. In rare cases, an angiogram may be needed to help determine the type of repair. However, in the vast majority of cases, the surgeon will know exactly where the injury is and further study is not needed. The catheter is then prepped along with most of the patient so that the operative repair can be completed.

Trends In Resident Trauma Operative Experience

Even though it’s called trauma surgery, the operative experience in trauma tends to be somewhat limited. This is due mostly to the fact that most trauma centers see predominantly blunt trauma. Yes, there are hospitals around the world where the penetrating injury load remains high and there is operative experience aplenty.

But in the US, the vast majority of trauma centers see mostly blunt trauma. Surgical residents in the US are required to log 10 operative and 20 nonoperative cases to successfully meet residency completion requirements. And blunt trauma is tending to get less and less operative in nature. A good example is the evolution of blunt solid organ injury to mostly nonoperative management.

So what is happening with surgical resident operative trauma experience? And has there been any impact from the work hour restrictions that have gone into effect in the US? A study from Harborview, Denver Health and Seattle Children’s looked at the ACGME operative logs for surgical residents annually from 1989 to 2010. They combined the data into 5 year blocks, with the last two having work hour restrictions in place.

Some interesting findings:

  • Overall mean caseload of major cases (all types) remained steady at about 925 per resident
  • Mean trauma operative caseload decreased from 76 to 39 (beginning of work hour restrictions)
  • Mean trauma operative caseload remained steady at 39 for the 7 years in which work hour restrictions were in effect
  • The number of intra-abdominal trauma operations decreased from 31 to 17, and the number of liver/spleen operations decreased from 5 and 4 to 3 and 2

Bottom line: Resident trauma operative experience has declined and stabilized in the US. This is due to the evolution of our management of blunt trauma. Unfortunately, this decline will reflect on how well prepared surgeons at outlying hospitals are, and in the quality of emergency surgery they may provide. The impact will be felt most by seriously injured patients who cannot be taken to a high level trauma center initially. We need creative solutions to address this issue, such as mini-clerkships in trauma or structured experiences at high level trauma centers for surgeons in outlying hospitals.
