Diagnosing Facial Fractures With CT

Leave a comment

Facial fractures are common after major blunt trauma. There are a number of diagnostic tests available for their diagnosis, including head CT, conventional facial imaging and facial CT.

Our preference has been to add a facial CT to the list of diagnostics in any patient with external evidence of facial trauma. Subjectively, it appeared that there were not many injuries being identified, and the vast majority did not require operative management. 

A review of the literature shows that head CT alone is sufficient for screening for significant facial fractures. A small retrospective series noted that the accuracy was 92%, with 90% sensitivity and 95% specificity. 

Bottom line: A head CT alone ordered for the usual indications is a very good screening test for facial fractures. If none are seen, it is unlikely that there are any fractures that require specific management. If fractures are seen, consultation with a facial surgeon is needed. However, unless the fractures involve critical areas (e.g. temporal bone near the middle ear) or are significantly displaced, the benefit of a facial CT scan is still very low since most will be treated without operation.

Will Our Phones Help Save Us From Being Distracted By Our Phones?

I’ve written many posts on the perils of texting and driving. Everybody knows it’s bad, but they still do it. It’s tough for police to detect, let alone enforce.

How to deal with this problem? Well now, there’s an app for that!

AdelaVoice has released a free app for Android phones that allows the user to interact with their phone without touching or even looking at it. It’s called StartTalking and lets the user send and listen to texts, post to Twitter or Facebook, as well as other tasks. To visit their website, click here.

I think that this app could dramatically improve road safety if it works as advertised. However, I also don’t think it’s the final answer, because research has also shown that just talking on the phone is a distraction and leads to accidents, too.

It will be very interesting to see where this type of solution leads us.

Disclosure: I have no financial interest in AdelaSoft or StartTalking. I don’t even own an Android phone!

Prone Positioning After Laparotomy

Leave a comment

Patients with serious abdominal injury may require a laparotomy, and a subset of these may need a temporary closure for damage control surgery. Concomitant spine injury may have your spine surgeons asking “is it safe to prone the patient who is postop with a midline incision or an open abdomen.” What to tell them?

There’s not much guidance out there in the literature. One paper from 2000 looked at four patients who were proned for severe ARDS and found that one suffered a wound dehiscence. However, this patient had severe generalized edema and was on several pressor agents. 

The use of temporary abdominal closure techniques has revolutionized the early management of severely injured trauma patients and has greatly decreased the incidence of complications from abdominal compartment syndrome. Several authors have now demonstrated that putting those patients in the prone position is well tolerated. 

As far as patients who have a closed laparotomy, proning appears to be well tolerated as well. One caveat: consider carefully if the patient is having wound complications or if they are morbidly obese.

The bottom line: Consider the risks and benefits carefully in any post-laparotomy patient you are considering prone positioning for. Other than in morbidly obese, it is generally considered safe, even in patients with damage control dressings in place. However, make sure the trauma surgeon re-evaluates the wound again as soon as the patient is returned to the supine position.

NEW: Indexed Archive for the Trauma Professional’s Blog!

Leave a comment

Over the past several months, I’ve wanted to refer to older blog entries while teaching our surgical and emergency medicine residents. However, I’m not completely satisfied with the search system available here on Tumblr, my blog host. And although the Archive View feature is fun (you can see a snapshot of entries by month), it’s still tough to drill down to a specific post.

I’m excited to announce an indexed version of the archive, which is now available at www.regionstrauma.org/blogs. This link opens a list of posts that are indexed by topic area. It’s now much easier to find something you are looking for, and it helps me avoid duplicating posts.

I have received occasional requests for a post on a specific topic, and I really enjoy responding to them. If you have a question about some trauma-related topic that you are “dying” to know the answer to, please email me or use the ask link to the right.
