Medical Care in TEOTWAWKI, by GeorgiaDoc

Monday, Aug 16, 2010

JWR's book "How to Survive the End of the World as We Know It" has motivated me to add a little more light for those who may be in a situation where a physician is not available, but caring for someone needing sophisticated medical care.

I am an Internist, and have been working in an urgent care setting for 20 years. Before that, I had a number of years experience working in several Emergency Rooms (ERs), and a trauma center. Since I am not formally trained in ER work, I have concentrated more on stabilizing patients to get them to more specialized care. I have no experience in battlefield injuries, like arms and legs blown off, or eviscerations, so I will not venture there.

My previous article focused on the common types of infections one is likely to encounter, and the most appropriate antibiotic. Please read the recent SurvivalBlog article for common infection treatment.

This article will go further into the weeds with antibiotic use.

This article is only for general medical information and should not be used for specific treatment. Always seek expert help for medical problems whenever possible.

Early in our medical training, medical students are taught the following principles of medical care,

1. Murphy's Law
"Everything that can go wrong, will go wrong."

2. Sutton's Law
Willie Sutton was a famous bank robber. When asked why he robbed banks, he retorted, "That's where the money is." Sutton's law is, "Go where the money is." [In emergency medicine] you don't mess around with treatments that might work, or do tests that might give you the answer. You go for the money the first time, because you might not get a second chance.

3. Hippocratic Oath and Principle
"First and foremost, do no harm." This is in the Hippocratic oath. If there is ever a question that you may cause more harm than good, you do not do it.

One of the first things medical students are taught is that all medications have "good" actions, which we call "therapeutic," and "bad" actions, we call "side effects," or allergic reactions.

Allergic reactions to medications are very common. Every G.O.O.D. bag should include benadryl. Take it immediately if you start itching after taking a medication. It might save your life. [In an emergency] if you have trouble breathing or swallowing [which are symptoms of anaphylactic shock], I would take benadryl, but I would also seek medical attention if possible. Adrenaline is called for here.

For the advanced student, choosing the correct antibiotic for an infection is critical. Choose the wrong antibiotic, and if the infection worsens, you are in a heap of trouble. My previous article was intended make the choice for the use of antibiotics as simple as I could, because most people have very little training in medicine. So my thinking was to make it as simple as possible. For those with some medical training, I will go a little deeper into the weeds.

Most infections are the result of some breakdown in our defense system, coupled with exposure to an infective organism. If we lived in a sterile bubble, we would never get an infection. But even with the exposure we have every day to zillions of virus' and bacteria, we still rarely become infected because we have complex systems to protect us from becoming infected. The first line of resistance is our skin. If it is in good shape, and intact, infections are rare. So pay attention to your skin. If it is dry, use moisturizing cream to keep it supple. If you are standing in water all day, take off your shoes and socks several times daily and air dry your feet. If you sweat a lot, air dry twice daily the areas that stay wet all the time to keep the skin in good condition.

Respiratory infections are best prevented by limiting exposure. If you are coughing, you should cover up when coughing, and wear a surgical mask. Most authorities believe that if you remain 6-8 feet from others, you are unlikely to spread a respiratory infection. You should also wear a surgical mask. These are not proven effective, but will capture large droplets if you cough or sneeze.

If someone is ill around you, you should be wearing an N-95 mask. The N-95 mask should be in everyone's survival plans. These masks really work to prevent contracting respiratory infections. They must fit snugly, and they are difficult to wear for extended periods of time, but they do work. They are inexpensive if you stock up in a non emergency situation. During the last flu epidemic they disappeared from the shelves, so stock up now. Make sure they are clearly labeled certified by OSHA as N-95.

For those interested in going deeper into the weeds for the use of antibiotics in TEOTWAWKI, I will discuss how MDs decide on the use of antibiotics. I am only discussing treatment of adults. This does not apply to children. Children are very different than adults. As a wise Pediatrician once told me, "Children are not small adults. They are biologically very different."

First some definitions:
1. Symptoms are those things the patient feels and describes to the doctor. Symptomatic treatment is treating the symptoms, not the underlying illness. So, taking Tylenol for fever is symptomatic treatment.
2. Signs are those things the doctor sees in his exam.
3. Malaise means just plain feeling lousy.
4. Virus. A virus is an odd creature, not able to live or reproduce on it's own. It causes disease by attaching to your cells, drilling a hole in your cell, and injecting it's DNA (or RNA) into your cell. It then takes over your cell mechanism, reproduces hundreds of copies of itself, ruptures your cell to spill the copies of itself into your body, and the process begins again. Antibiotics are worthless against them. There are a few anti-virals that work for herpes, influenza, chicken pox, and shingles.
5. Bacteria are fully living creatures which cause disease by growing and invading the tissue of your body. Antibiotics are highly effective if correctly targeted against the particular bacterium.
6. Prions are like creatures from the black lagoon. They are crooked proteins that will make all similar proteins crooked when they come in contact, and are very deadly. I know you have heard of Mad Cow disease [the common name of Bovine Spongiform Encephalopathy (BSE)] , and that it is caused by a virus. Actually, it is caused by a prion.

The first decision to be made is whether you are dealing with a viral infection, or a bacterial infection. This is usually fairly easy for a physician, as we see thousands of cases of each over our years of medical practice, and can tell pretty quickly with a brief history and physical examination. These are the things that usually differentiate viral and bacterial infections. None of the points are 100%, but if you look at all the differentiating features, you can make a pretty good judgment.

And why does it matter? It matters because viral illnesses are almost always self limited illnesses (they go away by themselves), so we treat them symptomatically. We do not use antibiotics as antibiotics are worthless in treating viral illnesses, and may cause harm (see the Hippocratic Oath above). However if it is a bacterial infection, it is important to use antibiotics promptly to avoid complications, even death.

There are exceptions, but typically viral illnesses will not be accompanied by a fever above 100.5 F. Usually there will not be swollen glands (infectious mononucleosis is one exception). There are usually systemic symptoms like achiness, fatigue, malaise. Bacterial infections are usually accompanied by fever over 100.5, may include swollen glands, and usually do not include the systemic symptoms.

Let me begin by describing the typical "viral syndrome." The most common viral illness is the common cold. It usually consists of a runny nose, nasal congestion, sore throat, and cough. There is usually not a fever over 100.5, and usually not any significant swollen glands in the neck. This is the classic viral syndrome, and although there are many virus' that can cause similar symptoms,

Another typical viral syndrome is Viral Gastroenteritis. This is very common. Some people think it is the "flu," and call it the "stomach flu," but it has nothing to do with "flu." It typically is an acute, sudden onset of nausea, vomiting, and watery diarrhea. There may be some cramping, maybe even a low grade fever of 100.5, rarely any higher. People usually feel terrible. Fortunately it usually only lasts a day or two. Food poisoning will do the same thing. If the diarrhea is bloody, or the cramping is severe, or the fever is above 100.5, or it lasts more than two days, then I would suspect a possible bacterial infection.

We often see patients with a sore throat concerned they have "strep throat." Strep throat is a bacterial infection of the throat. Patients with strep will typically have a sore throat, fever over 101, and swollen glands. Those with a cold will have a sore throat, runny nose, achiness, fatigue, and cough. Fever, and swollen glands will be absent.

Bronchitis is another viral syndrome. Unless you are a smoker, or have emphysema or some other chronic lung disease, bronchitis is almost 100% a viral illness. It is usually just a nasty cough without a fever. It is usually non-productive, and often becomes productive of clear sputum, which becomes discolored to yellow and green toward the end of the illness. Leave it alone. It will go away by itself.

Influenza is a little different. It is a viral infection, and is a little unusual in that it is accompanied by high fever, up to 103-104 even. Experienced MDs can tell easily though, because of the extreme fatigue associated with influenza, and the typical "viral syndrome" symptoms of cough, runny nose, sore throat, nasal congestion which accompany the illness Extreme fatigue is a hallmark of illnesses. Patients have difficulty getting out of bed to come to the doctor. And it has an abrupt onset. Within an hour or so, victims go from feeling fine, to feeling terrible with aches, extreme fatigue, followed by the fever and other symptoms.

With these viral syndromes understood, it becomes easier to recognize bacterial infections.

Pneumonia is a bacterial lung infection. Since it is a lung infection, you would expect a cough. Since it is a bacterial infection, you would expect a fever of 101 or higher. Since it is not viral you would not expect "viral syndrome" symptoms of runny nose, nasal congestion, sore throat. An important caveat for pneumonia is that it often develops as a complication of a cold because your resistance is down, then later the pneumonia sets in. Typically, a patient develops a "cold" with the usual runny nose, nasal congestion, sore throat, and cough without a fever. Then a week or so into the illness, suddenly a fever over 101 develops, the cough worsens, and becomes productive, sometimes blood tinged. This is the onset of pneumonia complicating a viral illness. (So you thought being a doctor was easy?)

Bacterial enteritis. This is a bacterial infection of the intestines. It is very similar to viral gastroenteritis, but is usually more severe, often accompanied by a fever over 101, and may include blood tinged diarrhea. There is usually a history of travel, and uncooked food eaten, or possibly contaminated water from a well or stream. If someone has viral gastroenteritis which is not getting better in 2-3 days, start thinking about a bacterial infection.

Clostridium difficile. This is a good time to mention this disease. This disease is one of many reasons doctors try to limit the use of antibiotics. It is a potentially serious complication of antibiotic use. Sometimes when taking an antibiotic, the normal bowel bacteria are killed off allowing this nasty bacteria to grow out. So if someone gets the typical diarrhea, cramps, sometimes low grade fever after taking antibiotics, it is probably clostridium difficile. This is treated with metronidazole.

Strep throat is a bacterial infection of the throat. So we would expect a sore throat, fever over 101, and swollen glands. If the patient has viral symptoms like cough, runny nose, nasal congestion, and does not have a fever, the odds are 20-1 or more it is a cold. Treat it symptomatically.

I discussed the treatment of these bacterial infections in my previous article.
