Administering Epinepherine
Q: What is the legality in administering epinephrine to someone? Are WFA certified individuals allowed to carry epi-pens to have someone use if in an emergency situation or can epi-pens only be used if they are prescribed to someone?

Like many questions, the answers depends. States vary in what they consider to be legal. Some have specific provisions for lay providers. Others strictly forbid administering medication to non-family members. Most are not clear. I believe that this is a first aid skill. So do the American Heart Association and the American Academy of Allergy, Asthma and Immunology. In Ontario, an Epi Pen can be purchased without a prescription. So where is the problem? It lies with the concept of the administration of a prescription medication by a non-licensed provider. Tens of thousands of people have been trained. I know that some of our graduates administer epinephrine each year. I am not aware of any bad outcomes, including adverse reactions or legal issues arising from administration of epinephrine by lay providers. Although many of us have written in defense of this procedure and organizations have lobbied on behalf of the training, a gray area still exists.

The most prudent approach when you are working for someone else would include the following:

  1. Training. – Keep your certification current.
  2. Authorization – Make sure that your employer knows about your level of training and has authorized you to administer the medication for any client should the need arise. Get your patient’s permission.
  3. Medication – Make sure that you have unexpired medication that is the correct concentration (if you are not using an autoinjector). It should be clear, colorless and free of any particulates. Your organization should supply the medication.
  4. Protocol/SOP – If you are using an organizational protocol (you should), make sure that it is current and approved. Review this at least yearly. In addition, there should be a regular accounting for the medication including the expiration date and disposal.
  5. Review – Anytime epinephrine is used (or should have been used), your employer should do a comprehensive review of the event, report back to the principles involved with the findings, and modify policy as needed based on this review.

If you administer epinephrine outside of a work setting, you still have the same responsibility to practice competently – current certification, unexpired medication, familiarity with your training protocol and patient permission.

In the relatively unusual likelihood it is medically necessary, epinephrine injection has proven to be an extremely low risk procedure for a significant benefit. I personally believe that the appropriate use of epinephrine for anaphylaxis is ethical and medically appropriate even where the legality might be questionable. Your employer should seek a legal opinion for your state. For more information on our view of the legal implications including the Good Samaritan legislation, a sample protocol or other articles on this or other topics, go to here.

Hypothermia Wrap Construction and Use

Wednesday, February 25th, 2009

The hypothermia wrap is for more than just severe hypothermia patients. It can be used for any patient that may be experiencing a cold challenge and is not able to adequately generate their own heat. For example, a skier with a lower extremity injury awaiting evacuation has cold challenge on their problem list.

Q: My son was diagnosed with mono

Wednesday, February 25th, 2009

Mono Recovery
“My son was diagnosed with mono last week. He is scheduled for philmon with the scouts on June 13. He is a 6′5 and swims high school & the YMCA teams. How do I know if he is OK to go on this.”

Assuming that you are referring to garden variety mono, caused by the Epstein-Barr virus, I suspect that you know that it is a very common viral illness. In fact, most of us will have contracted it by the end of our 3rd decade. Clinically, it can vary between minimal symptoms to a significant illness with total body implications that can make one feel miserable. Hospitalization is unusual. Not knowing your son or how sick he is/was, I will offer you some suggestions.

Given the potential activity at Camp, the major worry involves spleen enlargement that usually but does not inevitably occur with mono. The spleen is a blood filtering organ that resides under the L side of the diaphragm. When it enlarges, it emerges from the protective shield of the rib cage. This less protected location plus its more fragile transformation make it significantly more vulnerable to injury. If it breaks, potentially lethal internal bleeding can occur.

Most prudent practitioners warn against physical activities that could result in an injury to that area (e.g., contact sports, falls, heavy lifting) until it returns to its normal size, location and structural integrity. There is no hard and fast rule, but this prohibition should be in effect until the spleen can no longer be felt on examination. Have his health practitioner confirm this. A month for most people should be sufficient.

Otherwise, a person’s well being should be the rule. Most people are wiped out for a few weeks. Although recovery time is highly variable, most people are back to near-normal activity within 6 – 8 weeks.

Bottom line: Once the spleen has retreated to its normal spot, his personal well being is the most important factor. Just make sure that he does not do too much too soon. Quarantine is not an issue.

Q. Once a person has had an anaphylactic reaction to a substance

Wednesday, February 25th, 2009

Q: Once a person has had an anaphylactic reaction to a substance, will all subsequent exposures invariably lead to similar or worse reactions?

There is no question that recurrent reactions can follow re-exposure. As it turns out, however, the probability as reported in the medical literature is considerably less, about 50% for bee stings, for example. These re-exposure reactions can be less severe than the prior reaction.
Taking reasonable steps to avoid re-exposure is as important as being prepared to recognize and treat a reaction should it occur. For some people with recurrent severe reactions, immunotherapy (aka desensitization) can be a very effective deterrent. It is equally important to remember, however, that based on these statistics, not everyone needs to be treated following a re-exposure. Only treat those who develop signs and symptoms consistent with a true anaphylactic reaction.

“These WFR dreams are getting crazy!”

Tuesday, February 17th, 2009

During a Wilderness First Responder course at the University of WI at LaCrosse, Ann Dunphy, one of WMA’s instructor’s, asked students about WFR dreams, as she does with all of her courses. Interestingly enough, one student, D. Crye, was willing to share his story, and thankfully for us, he also shared it with the WMA office. We just had to post it!

Did anyone leave a plastic bag in the refrigerator with a Leatherman Blast, smartwool socks and V8 Butternut Squash soup? Let me know!

Also, for those who want to hear a dream I had last night feel free to keep reading; I’ll make it short. I dreamt last night that I got to save a guy from drowning in a river after he drove into a frozen lake. It was crazy because we got him out of the water and carried him up a very steep bank. As we got him onto the street he starting throwing up gallon after gallon of water. It was a lot of water! The whole time we were trying to keep him stabilized because we were MOI spine of course. Well this guy didn’t want to stay still but we finally got him to stay laying down as we waited for the ambulance. But I was so excited that I was able to help rescue someone that I left my patient (not a good thing) to go tell Ann, who was down the road at some outdoor store purchasing a new first aid kit. I got there and started telling Ann how great it was and everything and then she was like “David, where is your patient now?” And I told her he was laying in the middle of the street by himself. So Ann said “Get back to your patient now!” So, I ran back. When I got back to my patient the ambulance had arrived and had him on a stretcher, but they also had two other people on stretchers too! I was freaking out because somehow there were 3 patients instead of just one! Furthermore, all of them were strapped down on there backs throwing up everywhere uncontrollably. I then sat down and started to realize all that I did wrong. First of all, I didn’t complete the first triangle to find out how many patients there were. Secondly, I didn’t complete a full SAMPLE history because I must have missed something because everyone was throwing up big time from something. And I shouldn’t have left my patient to go tell Ann what had happened. So, I learned some good lessons from my dream. These WFR dreams are getting crazy!

Snakebite Treatment Methods

Monday, February 16th, 2009

 

Click on the link above to go to www.wildmed.com and ask Dr. Johnson a question!

I’m fact-checking a piece for a national outdoor magazine. I have several questions about snake bite treatment methods:

  1. Is there any benefit to the "cut-and-suck" method or should we get rid of it altogether?
  2. What is your professional opinion on the effectiveness of suction devices?
  3. Should a responder apply a tourniquet to a snake bite victim?
  4. Should a coldpack be applied to a snake bite victim?
  5. Is marking the edge of the bite to track the swelling helpful to medical personnel?

Answers:

  1. No, none.  In fact, it could result in an infection, impair healing and the cut could cause an unintended injury.
  2. Useless.  A nice study done a few years ago demonstrated their lack of efficacy.  Their reputation was based on hype and not science.
  3. Never a tourniquet.  For some with neurotoxins, especially the most potent ones found outside of NA, a compression wrap may be helpful.
  4. It will not help and could cause more injury.
  5. Yes, it could be.

Remember all snakes are not the same.  There are different general kinds of toxins. The management of each is directed at the damage or harm that could result

 


Cross Country Skiers and Compartment Syndrome

Monday, February 16th, 2009

In the musculoskeletal system lecture WFR students learn about the signs and symptoms of compartment syndrome. Repetitive stress is a cause for compartment syndrome to the lower legs.

These two articles are accounts from Olympic ski racers that are suffering from compartment syndrome.

CPR: Understanding the Rate of Chest Compressions

Wednesday, February 11th, 2009

The CPR mantra is push hard and push fast. But what is hard and what is fast?

The utility of chest compressions in the wilderness context is dependent on the underlying cause for arrest. For example, a patient that has no pulse and breathing after a loss of consciousness underwater had a healthy heart at the time of arrest. Chest compressions and rescue breathing may provide the oxygenation and perfusion for return of spontaneous circulation. If the patient’s cardiac arrest was caused by a myocardial infarction CPR alone will not fix the underlying problem. It just buys time. The patient needs an AED, paramedics, and a hospital. Quickly!

WMA Assistant Instructor Tim Sheehan supervises paramedic students during their hospital emergency department training. According to Tim many students struggle to maintain the proper rate of 100 compressions per minute. Tim says, “If you are going to do CPR you might as well do it right.”

Well how do you know if you are doing 100 compressions per minute?

Tim tells us, “All of the code carts in the emergency department have a metronome.” A metronome is a simple tempo device that clicks or beeps at a prescribed beats per minute.

Two online metronomes are available at
http://webmetronome.com/or http://www.metronomeonline.com/. You might be able to load a metronome into your smart phone or PDA.

If you don’t have access to a web based metronome sing the famous Bee Gees song, Stayin’ Alive, as you compress. Barry and the boys are grooving at about 100 beats per minute.
