I really wish that there was a comparison some where of how fast the strips work versus the liquids and tablets. Before I found the strips I was considering using the Childrens Benadryl Perfect Measure, but they are really bulky. I just looked them up and they are 12.5 mg each compared to the normal adult dosage of 25mg, so another reason not to carry them unless you have kids.
Random thoughts from a sleep deprived paramedic....
1. Do explain to your companions how to use your epipen. The frequency of thumb injections is disturbing. Having 2 patients in the back of an ambulance isn't typically fun, or conducive to recieving good care- especially considering the lifesaving medication that you needed 5 min. ago is now dripping out of your buddies bloody thumb.
2. Benadryl- When I give it IV, it still takes 15 to 20 minutes to begin working. If you are taking it PO, it will take longer. Yes, it is a useful second line treatment. No, it is not going to help you with the acute, life-threatening symptoms.
3. Multiple epi doses- talk to your MD. Epi is hard on your heart. It increases contractility, rate, automacity. If you have cardiac problems these effects can lead to bad stuff- infarction and/or arrythmia. If your airway is swelling shut though, a heart attack might be relatively low on your list of immediate concerns. Talk to your doc.
4. Airway management- this is nightmare territory for paramedics, ER docs, and everyone else who manages airways. If it is a severe reaction, an OPA isn't going to cut it. Intubation will range from incredibly difficult to impossible- and if successful, it will often be of a inadequate size to maintain adequate perfusion. Cricothyrotomy anyone?
5. Please don't drive yourself to the ER after all of this. You will be gorked from the epi crash plus all of the antihistamines. Plus, there is the chance of the symptoms coming back. Let us do that. We are nice folks, for the most part.
Wilderness first aid issue.
What do you think of advice for anaphylactic shock that only discusses use of an EpiPen? It was my impression that giving/taking antihistamines was also critical? Did the conventional wisdom change when I wasn't lookin'?![]()
The need to administer an epi-pen dose is also supposed to be followed by medical treatment.
The advice you relate is the same as the advice that I thought that I recalled for wilderness cases of anaphylactic shock. The rationale for the order of medication was, IIRC, that if the victim passed out, you could use the EpiPen but the victim could no longer swallow the Benydryl. In contrast, in a non-wilderness setting, treatment with medicationsto follow up the temporary effects of an EpiPen would not be precluded by unconsciusness.I was told to take the Benydryl and then the Epi and go to the ER ASAP. This was advice from an expert in the field of anyphylaxis, academic and clinical. But I have never seen if/how well this works, fortunately.
The message I took away from it all is that it is best to see a specialist and have him assess the situation, look for triggers and based on knowing you, your job, family,etc. give you the most likely course of future events and how to handle them.
Respectfully, Eyegor, I have been given conflicting diagnosis and advice on personal medical issues by Board-Certified physicians. I fear that conflict in advice is not dispositive. I guess I am looking for information to guide a search of reputable authorities, hoping to find a consensus in THEIR advice.DO NOT RELY ON THE INTERNET FOR MEDICAL TRAINING!
The question assumes anaphylactic shock. My understanding is that anaphylactic shock is a severe allergic reaction.Also anaphylaxsis and an allergic reaction are NOT the same.
As noted, BSA suggests consultation with a physician before setting off. The issue that motivated my question is discussing the EpiPen as the sole option for first aid in the wilderness.Administration of medication should always be taken seriously. Epi-pens can be lifesavers. They are also capable of killing someone, either directly or indirectly. Please seek professional training or at the minimum talk to your personal physician about specific situations regarding you or your family.
Why, please? You are not alone in that ordering of treatment, but all the sources I can locate do not discuss first aid in a wilderness setting where professional care is most probably hours away - hours after the EpiPen wears off.Now that the disclaimers are out of the way, my advice is that in a true medical emergency epi comes before diphenhydramine.
Again, the question assumes anaphylactic shock for whatever reason. Again, I thought anaphylactic shock was an allergic reaction of a particularly severe and widespread nature. But I am certainly not a former spert.Treating an allergic reaction OTOH, start with the benadryl and monitor.
Again, the question assumes we are in the wilderness. No EMS for hours,at best. Highly probable that there willl be no "drive" either (We could be dealing with people on vehicles in the wilderness.).If epi is aministered it is time to get help. This may mean EMS, it may mean having a group member drive. In any case, your day is done.
Closed? By no means. Still looking for an authority who expressly says, in words or substance, "Here's how you deal with it in the wilderness."
What causes Anaphylaxis?
Why some people develop anaphylaxis and others not, is difficult to explain. But it usually happens to people who are known to have allergies and particularly those who suffer with brittle asthma.
The most common cause of anaphylaxis in the community is from eating a food to which you are allergic such as nuts, peanuts, eggs, fish and shellfish. Peanuts and tree nuts (such as Brazil nuts, Hazelnuts, Almonds and Walnuts) are the foods most likely to provoke a reaction.
Even eating a tiny amount of a particular food can cause anaphylaxis. Some people are so sensitive that the food essence can trigger a reaction (as in a Restaurant when the person at the next table is eating fish).
Allergy to venom from wasp stings can cause anaphylaxis as can allergy to latex and drugs such as penicillin, codeine and aspirin. Bee Allergy is less common in the UK.
In the hospital context, the majority of anaphylactic reactions are to medicines such muscle relaxants, antibiotics and injectable medications including anaesthetic agents. Latex allergy and anaphylaxis is becoming an ever increasing problem, particularly in health workers and children who have frequent operations and are sensitised by exposure to Latex in surgical gloves, drip sets and catheters.
Sometimes we never find the cause of the anaphylactic reaction and in 1978 the term "Idiopathic" Anaphylaxis was coined to describe this group of people.
Symptoms of Anaphylaxis
Anaphylaxis comprises a group of symptoms and features, which in combination lead to a generalised severe allergic reaction with respiratory difficulties and circulatory shock.
The initial reaction is swelling and itching of the area which the allergen has entered. Food for example initially causes swelling and itching of the mouth and throat while a wasp sting will cause intense itching and swelling at the sting site.
A generalised reaction then rapidly follows with an itchy rash that spreads over the whole body. The face and soft tissues begin to swell and breathing becomes difficult. The palms and soles of feet become intensely itchy.
The person becomes very agitated with a “feeling of impending doom”, tightening of the throat and chest occur, while the blood pressure may begin to drop and the victim then loses consciousness.
These symptoms develop very rapidly within a few minutes of coming into contact with the allergen. Most anaphylactic reactions occur within an hour of exposure to the causative allergen.
Treatment
Anaphylaxis needs to be treated as a matter of urgency as the symptoms of respiratory obstruction and shock develop rapidly. Emergency treatment consists of an injection of a drug called adrenaline or epinephrine, which raises blood pressure, relieves breathing difficulties and reduces swelling. Once adrenaline has been given, people normally recover very quickly. They should also immediately take a dose of antihistamine and may even need a short course of cortisone tablets.
If you have had a previous and severe anaphylactic reaction, make sure you use the Adrenaline Injector [EpiPen] straight away with any future reactions – as any delay puts you at far greater risk for collapse and dying. Although many people carry an Epipen, the most common cause of death is failure to use it. There are two types of injector, one for children and another for adults. The injector is easy to use and is activated by pressing firmly against the front of the thigh muscle. Your doctor should issue you with a “trainer” Epipen to practice self-administration.
If you have always experienced milder attacks with minimal or no breathing difficulties we usually recommend that you immediately take antihistamine medication and monitor the situation for a few minutes before giving adrenaline. Milder symptoms then usually resolve over the next half hour. Always make sure you have someone with you who knows about your condition and who can seek further help if necessary.
Make sure that you do not exert yourself, have a hot bath or get hot, rather remain cool, as increased circulation can lead to more severe and rapid allergic reactions
All people who have had anaphylaxis should go to the local hospital Emergency Unit for further observation. This is because when the adrenaline wears off they may need further treatment, such as antihistamines, corticosteroids and occasionally oxygen and intravenous fluid therapy. We would also recommend that you go to your local hospital and introduce yourself to the medical team so that they are aware of your anaphylactic tendency. There is a risk of developing a delayed reaction some hours after the initial reaction and you should remain in the Emergency Unit for at least 4 hours for observation.
First aid measures
Emergency care for someone with suspected anaphylaxis
· If the person is conscious and having breathing difficulties, help them to sit up. If they are shocked with low blood pressure, they are better off lying flat with their legs raised.
· If the person is unconscious, check their airways and breathing and lie them in the recovery position.
· If you know that the person is susceptible to anaphylaxis, check if they carry a preloaded adrenaline syringe (EpiPen). If necessary, help the person to inject it into the muscle of the thigh. This can be administered through clothing.
· Dial 999 for an ambulance and tell the controller that you think the person may have anaphylaxis. If available, antihistamine and steroid tablets should also be givenAlternative Names
Anaphylactic reaction; Anaphylactic shock; Shock - anaphylactic
Definition
Anaphylaxis is a life-threatening type of allergic reaction.
Causes
Anaphylaxis is an severe, whole-body allergic reaction. After being exposed to a substance like bee sting venom, the person's immune system becomes sensitized to that allergen. On a later exposure, an allergic reaction may occur. This reaction is sudden, severe, and involves the whole body.
Tissues in different parts of the body release histamine and other substances. This causes the airways to tighten and leads to other symptoms.
Some drugs (polymyxin, morphine, x-ray dye, and others) may cause an anaphylactic-like reaction (anaphylactoid reaction) when people are first exposed to them. This is usually due to a toxic reaction, rather than the immune system response that occurs with "true" anaphylaxis.
The symptoms, risk for complications without treatment, and treatment are the same, however, for both types of reactions.
Anaphylaxis can occur in response to any allergen. Common causes include:
Drug allergies
Food allergies
Insect bites/stings
Pollens and other inhaled allergens rarely cause anaphylaxis. Some people have an anaphylactic reaction with no known cause.
Anaphylaxis rarely occurs. However, it is life-threatening and can occur at any time. Risks include past history of any type of allergic reaction.
Symptoms
Symptoms develop rapidly, often within seconds or minutes. They may include the following:
Abdominal pain or cramping
Abnormal (high-pitched) breathing sounds
Anxiety
Confusion
Cough
Diarrhea
Difficulty breathing
Fainting, light-headedness, dizziness
Hives, itchiness
Nasal congestion
Nausea, vomiting
Sensation of feeling the heart beat (palpitations)
Skin redness
Slurred speech
Wheezing
Exams and Tests Return to top
Signs include:
Abormal heart rhythm (arrhythmia)
Fluid in the lungs (pulmonary edema)
Hives
Low blood pressure
Mental confusion
Rapid pulse
Skin that is blue from lack of oxygen or pale from shock
Swelling (angioedema) in the throat that may be severe enough to block the airway
Swelling of the eyes or face
Weakness
Wheezing
The health care provider will wait to test for the specific allergen that caused anaphylaxis (if the cause is not obvious) until after treatment.
Treatment
Anaphylaxis is an emergency condition requiring immediate professional medical attention. Call 911 immediately.
Check the ABC's (airway, breathing, and circulation from Basic Life Support) in all suspected anaphylactic reactions.
CPR should be started, if needed. People with known severe allergic reactions may carry an Epi-Pen or other allergy kit, and should be helped if necessary.
Paramedics or physicians may place a tube through the nose or mouth into the airway (endotracheal intubation) or perform emergency surgery to place a tube directly into the trachea (tracheostomy or cricothyrotomy).
Epinephrine should be given by injection in the thigh muscle right away. This opens the airways and raises the blood pressure by tightening blood vessels.
Treatment for shock includes fluids through a vein (intravenous) and medications that support the actions of the heart and circulatory system.
The person may receive antihistamines such as diphenhydramine, and corticosteroids such as prednisone to further reduce symptoms (after lifesaving measures and epinephrine are administered).
This is the universal advice that I can find in the last couple of days - Epi first. Still, they all are implictly or explicitly in the context of fast access to professional medical care - not such care 10, 20, or 30 hours later.WEMTs will normally use Epi first due to limited time. You need to stop the histamine cascade before swelling occludes the airway. In the ABCs if you lose A, nothing else matters. Some ALS providers can do needle crics or a surgical cric. Others cannot. In any event, your patient is now in extremis. You asked about other treatments. Monitor ABCs (Airway, Breathing, and Circulation). Don't forget; Anaphylactic shock. Treat for shock.
You didn't say "Do nothing." I didn't say "Do Nothing." We agree. Is there a problem with raising the question just in case you and I are not the Final Authority?No one has said do nothing. Be prepared and Do Your Best.
Do you think the pamphlet in question should mention ONLY an EpiPen? That the question that I posed and which brought me here in a quest for more info. I thought, subject to being convinced otherwise, that even an overview should mention promptly administering antihistamines.Also remember, merit badge pamphlets are just that, pamphlets. They are not manuals, textbooks, or in depth tomes of knowledge. Only an overview.
I did look at the First, Second and Third Editions of the Fieldbook. The Third Edition Fieldbook did have a brief section on wilderness survival (15 pp) and another on first aid. All three had lots of information on skills useful in survival. None of the books mentioned any particular treatment for anaphylactic shock. The current Fieldbook has no sections on wilderness survival or first aid. http://www.bsafieldbook.org/fieldbook.jspA great place to start is the BSA Fieldbook chapter on Survival,. Better than the WS pamphlet IIRC. It has been many years though.
I rang up the board certified allergist/ immunologist. The first words out of his mouth were, "That's why you have an Epi-Pen." I mentioned antihistimine and he said, "yes". Later he brought up prednisone. As we spoke I could see that treatment could be delivered on a case by case basis and with more medical knowledge/experience and/or supplies there are many techniques that could make a difference.This is the universal advice that I can find in the last couple of days - Epi first. Still, they all are implictly or explicitly in the context of fast access to professional medical care - not such care 10, 20, or 30 hours later.
