Cool EMS Stuff: The Backboard Washer!

Backboards are made to get messy. And every time your friendly EMS provider brings you a patient, they invariably have to swab it down to give the next patient a reasonably sanitary surface to lie on. But sometimes the boards get downright nasty and the cleanup job is a major production.

Enter… the backboard washer. I recently saw one of these for the first time at a Level III hospital in Ohio. Fascinating! Pop the board inside and seven minutes later it’s clean. And I mean really squeaky clean. You may think it looks clean and a good hand wash, but just take a look at the effluent water coming out of this washer!

These units use standard 100V 20A power and only require a hot water hookup and a drain. They can wash two boards at once.

Hospitals in the know need to locate one of these next to a work area for completing paperwork and some free food. What could be better?

Are We Transporting Our Patients In The Correct Position? Part 2

[Note to prehospital providers: please comment below or email with your experience using this position.]

In my last post, I discussed the only paper I could find on the lateral trauma position (LTP). It was a survey that was taken 5 years after implementation of this transport position in Norway. Is there anything else out there that may help give us guidance on proper positioning during transport?

Just this month, a paper was published that tries to look at this issue from a different viewpoint. Since we can’t really show that the LTP is good or prove that it is truly safe, can we at least demonstrate that supine positioning might be bad?

 A very diverse group of researchers in Norway performed a systematic literature review and meta-analysis of everything they could find published on supine positioning and airway patency in unconscious trauma patients, especially when compared to lateral positioning. This was carried out from the beginning of time, or 1959 in this case.

See if you can follow their progress:

  • There weren’t really any good studies using this global search, so they broadened it to include trauma patients with decreased level of consciousness.
  • Oops! There weren’t any studies using this broader definition, either.
  • The authors wanted to use morbidity and mortality as their outcomes. But, there weren’t any good studies for this either so the decided to use indirect outcomes such as hypoxia, hypercapnea, hypoventilation, work of breathing, and a bunch of other stuff.
  • Oops again! There weren’t any studies reporting these indirect outcomes. 
  • But when these two indirect searches were combined, a number of papers (20) were identified that were used for a meta-analysis
  • A number of these papers showed soft results (language like ”indication of”, “small difference”). The only significant results were found in patients with known obstructive sleep apnea.

Bottom line: The use of the lateral trauma position is an intriguing concept, and has been used successfully in Norway for about 10 years. Intuitively, it makes sense, especially in obese patients or those with known obstructive sleep apnea. Unfortunately, this paper approached the questions asked kind of backwards, in my opinion.

I believe that LTP has a place in prehospital care, but that there will be significant barriers to adoption in most countries. In order to overcome these hurdles, clear protocols and positioning instructions will need to be developed, as well as specific indications. And it wouldn’t hurt to do a few good studies along the way. The Norwegians have helped us with the ethics questions, as it is the standard of care in that country. So write your local IRB and get busy!

Are We Transporting Our Patients In The Correct Position? Part 1

Here’s a kick in the head, unless you are one of my Norwegian readers.

In the US and many (most) other countries, trauma patients are routinely transported strapped down in the supine position. It’s tradition. It’s easy. It gives prehospital providers pretty good access for whatever they need to do.

But it is right? Some patients, particularly those who have a diminished level of consciousness or severe obstructive sleep apnea, or both, may not do well in that position. In 2005, Norwegian Emergency Medical Services (NEMS) introduced the use of the lateral trauma position (LTP) across the country. Here is how it looks:

Five years later, a group from several hospitals across Norway conducted a survey of all ground and air EMS providers in the country. A few factoids:

  • This one year survey included 202 of 206 ground EMS stations and 23 of 24 air EMS stations. Questionnaire response rate was about 50%
  • Of supervisors at ground EMS units, 75% said that they had implemented LTP
  • 67% of ground units had written policies for use and 73% had provided training
  • Individual ground provider opinions were a bit different. 89% were familiar with LTP, but only 58% actually used it.
  • Training seemed to be the key. Of ground providers given training, 86% were confident in using LTP, but of those not given training, only 58% were.
  • Only 53% of air services used LTP, and only one had a protocol.

Here are the instructions on how to do it:

Bottom line: Interesting concept. Unfortunately there is little (or no) objective data to help us. The main thing available now is a 10 year experience with the lateral trauma position in Norway, and I have not seen any analyses of it. In my next post, I’ll review a meta-analysis published this year that does try to compare LTP vs supine positioning.

Using The Slide Board In The ED

I’ve written several times on the importance of getting patients off the backboard promptly in the ED, but the topic keeps coming up! Many hospitals use slide boards to facilitate patient movement on and off the ED cart when undergoing imaging studies. How should we manage the use of this device?

There is no difference between a backboard and a slide board to the patient. It’s hard and uncomfortable to lie on for any period of time, and can cause soft tissue injury. To trauma professionals in the ED it is thinner, less bulky, easier to manipulate, and does not interfere with xrays as much. We tend to pay less attention to it than a backboard. Although it does not immobilize the spine as well as a backboard does, the difference is not clinically significant (in a cooperative patient). Remember, if your patient actually has a spine fracture, they will be placed on logroll precautions on a soft mattress only somewhere in your hospital! No stiff boards of any kind!

Slide board management tips:

  • Slide boards are for blunt trauma only! Patients with penetrating injury may need an upright chest xray in the ED and the board won’t flex enough.
  • Insert the slide board in any patient who will be getting several diagnostic studies. For trauma activation patients, this can occur as you roll them off the backboard.
  • As soon as diagnostic studies are done, remove the slide board
  • If there are unforeseen delays, remove the slide board and reinsert when ready to move
  • Remember that the soft tissue timer is counting down as soon as the patient is placed on a backboard or slide board
  • Plan an efficient road trip through diagnostic studies for your patient. This allows you to minimize time on the board. 
  • Repeated logrolls onto and off of the slide board are discouraged. Every roll is an opportunity for mishap.
