Nursing Tips for Managing Pediatric Orthopedic Trauma

Nurses have a complementary role with physicians in caring for children with orthopedic injuries. Typically, the child will have been evaluated and had some sort of fracture management implemented. In children, nursing management is easer than in adults since a child is less likely to need an invasive surgical procedure. Many fractures can be dealt with using casts and splints alone.

Here are a few tips for providing the best care for your pediatric patients:

  • Ensure adequate splinting / casting. You will have an opportunity to see the child at their usual level of activity. If it appears likely that their activity may defeat the purpose of the cast or splint, inform the surgeon or extender so they can apply a better one.
  • Focus on pain control. Nothing aggravates parents more than seeing their child in pain! Make sure acetominophen or ibuprofen is available prn if pain is very mild, or scheduled if more significant. Ensure that mild narcotics are available if pain levels are higher. Remember, stool softeners are mandatory if narcotics are given.
  • Monitor compartments frequently. If a cast is used, check the distal part of the extremity for pain, unwillingness to move, numbness or swelling. If any are present, call the physician or extender and expect prompt attention to the problem.
  • Always think about the possibility of abuse. Fractures are rarely seen in children under 3, and almost never if less than 1 year old. If you have concerns about the physical findings or parent interactions, let the physician and social workers know immediately.

In The Next Trauma MedEd Newsletter: Massive Transfusion

The next Trauma MedEd newsletter will be released later this month. In this issue, I will cover the good old Massive Transfusion Protocol (MTP) in detail.

Topics will include:

  • How to build a good MTP for your hospital
  • Analysis of the various parts of the MTP
  • How to accurately trigger your MTP
  • What’s the right “ratio” of products to give?
  • How does TEG fit into the MTP
  • and more!

As always, this issue will go to all of my subscribers first. If you are not yet one of them, click this link to sign up now and/or download back issues.

Unfortunately, non-subscribers will have to wait until I release the issue on this blog, about 10 days later. So sign up now!

New Tech: Augmented Reality In The OR?

Virtual reality headsets have been all the rage for some time. They immerse the wearer in a complete virtual world, and are typically used for gaming. Augmented reality, on the other hand, overlays virtual items on the real world so both are visible at the same time. Think the notorious Pokemon Go app:

What if this technology could be used for medical purposes? You could overlay diagnostic or anatomic information on your patient to help guide therapy, surgery, etc.

A group at the University of Alberta in Canada have been playing with this technology. ProjectDR takes any kind of image-related information and projects it directly on a patient.The patient is first scanned using surface markers like they do when making movies:

Obviously, no fancy suit or huge number of markers is needed. Once this is accomplished, the diagnostic information can be projected onto the patient. The patient can move, and the projector will compensate and keep the projection anatomically correct.

Here is a short video that demonstrates the system:

So is this useful? Unfortunately, not yet. It may eventually be good for office-based trauma professionals, but it needs further refinement. This version uses an actual digital projector, which means it will be subject to shadows which will interfere with viewing, especially if a surgeon gets his or her big head in the way.

Here’s how it will really have to work: The system could function quite well in surgical procedures. Imagine the surgeon being able to don a VR headset (lightweight, please!) and see the surgical field with key information overlaid on the display. Or even easier, incorporate it in the DaVinci robotic system display. Add vital signs in the upper corner and details of anatomic structures that have not been surgically exposed yet. It could help show anatomic anomalies in great detail, such as vascular variants. And heck, why not throw in some on-demand magnification as well?

As with most new and exciting tech that hits the general media, a version that is actually usable by clinicians is several years away. But it should be fun when it finally gets here!

Pop Quiz: What’s The Diagnosis? The Answer

Okay, time for the answer. This 12 year old crashed his moped, taking handlebar to the mid-epigastrium. Over the next 3 days, he felt progressively worse and finally couldn’t keep food down.

Mom brought him to the ED. The child appeared ill, and had a WBC count of 18,000. The abdomen was firm, with involuntary guarding throughout and a hint of peritonitis. The diagnosis was made on the single abdominal xray shown yesterday. Here is a close-up of the good stuff?

Emergency docs, your differential diagnosis list with this history is a pancreatic vs a duodenal injury based on the mechanism.

Classic findings for duodenal injury:

  • Scoliosis with the concavity to the right. This is caused by psoas muscle irritation and spasm from retroperitoneal soiling by the duodenal leak.
  • Loss of the psoas shadow on the right. Hard to see on this xray, but the left psoas shadow is visible, the right is not. This is due to fluid and inflammation along this plane.
  • Air in the retroperitoneum. In this closeup, you can actually see tiny bubbles of leaked air outlining the right kidney. There are also bubbles along the duodenum and a few along the right psoas.

We fluid resuscitated first (important! dehydration is common and can lead to hemodynamic issues upon induction of anesthesia) and performed a laparotomy. There was a  blowout in the classic position, at the junction of 1st and 2nd portions of the duodenum. The hole was repaired in layers and a pyloric exclusion was performed, with 2 closed drains placed in the area of the leak.

The child did well, and went home after 5 days with the drains out. Feel free to common or leave questions!
