Remaining whole and healthy in a survival situation is something we all strive for. But what happens if an accident, or worse, an attack, results in wounds that need tending? This is a question that every prepper asks themselves.

 

It is fairly easy to accumulate supplies for first aid and wound control but what about the tools you will use to tend to the hurt or wounded member of your group? Given an austere setting where traditional medical facilities are not available, how do you ensure that your instruments are clean, sterile, and fit for use?

 

How-to-Disinfect-and-Sterilize-Medical-Instruments-in-a-Survival-Situation.jpg

 

These are important questions and to provide you with answers, Dr. Joe Alton is back with some advice not only relative to six ways you can sterilize your medical supplies, but also a general discussion of clean versus sterile and the difference between disinfectants, antiseptics, and antibiotics.

 

Sterilizing Instruments In Austere Settings

 

 

A significant factor in the quality of medical care given in a survival situation is the level of cleanliness of the equipment used. You may have heard of the terms “sterile” and “clean”. Certainly, ideal conditions warrant both, but they are actually two different things.

 

Do you know the difference?

 

Sterile Vs. Clean

 

 

When it comes to medical protection, “sterility” means the complete absence of microbes. Sterilization destroys all microbes on a medical item to prevent disease transmission associated with its use.

 

To achieve this, we want to practice “sterile technique”, which involves special procedures using special solutions and the use of sterile instruments, towels, and dressings. Sterile technique is especially important when dealing with wounds in which the skin has been broken and soft tissue exposed.

 

Of course, it may be very difficult to achieve a sterile environment if you are in the field or in an extremely austere setting. In this case, we may only be able to keep things “clean”. Clean techniques concentrate on prevention of infection by reducing the number of microorganisms that could be transferred from one person to another by medical instruments or other supplies. Meticulous hand washing with soap and hot water is the cornerstone of a clean field.

 

If you are going to be medically responsible for the health of your people in a survival setting, you will have to strike a balance between what is optimal (sterility) and what is, sometimes, achievable (clean).

 

The “Sterile” Field

 

 

When you’re dealing with a wound or a surgical procedure, you must closely guard the work area (the “sterile field”) to prevent contact with anything that could allow micro-organisms to invade it. This area is lined with sterile “drapes” arranged to allow a small window where the medical treatment will occur.

 

Although there are commercially-prepared drapes with openings already in them (“
”), using a number of towels will achieve the same purpose, as long as they are sterile.

 

The first step is to thoroughly wash any item you plan to reuse before you sterilize it. Using a soft plastic brush removes blood, tissue particles, and other contaminants that can make sterilization more difficult. Consider using gloves, aprons, and
.

 

6 Ways to Disinfect and Sterilize Instruments

 

 

Now, the question of how to sterilize your medical supplies: There are a number of ways that you can accomplish this goal. I list them below in approximate order of effectiveness.

 

1. Simply placing them in gently boiling water for 30 minutes would be a reasonable strategy, but may not eliminate some bacterial “spores” and could cause issues with rusting over time, especially on sharp instruments like scissors or knives.

 

Note: always sterilize
in the “open” position.

 

2. Soaking in bleach (Sodium or
). 15-30 minutes in a 0.1% solution of bleach will disinfect instruments but no longer or rusting will occur. Instruments must be rinsed in sterilized water afterward.

 

3. Soaking in 70% isopropyl alcohol for 30 minutes is another option. Some will even put instruments in a metal tray with alcohol and ignite them. The flame and alcohol, or even just fire itself (if evenly distributed) will do the job, but eventually causes damage to the instruments.

 

4. Chemical solutions exist that are specifically made for the purpose of high-level disinfection (not necessarily sterility) in the absence of heat, something very important if you have items that are made of plastic. A popular brand is
, a trade name for a solution with phthalaldehyde or glutaraldehyde as the active ingredient.

 

Insert the instruments in a tray with the solution for 20 minutes for basic disinfection. Soaking overnight (10-12 hours) gives an acceptable level of “sterility” for survival purposes. There are test strips which identify when the solution is contaminated. If negative, you can reuse it for up to 14 days. As an alternative, some have recommended using 6-7.5% hydrogen peroxide for 30 minutes (household hydrogen peroxide is only 3%, however).

 

5. Ovens are an option if you have power. For a typical oven, metal instruments are wrapped in aluminum foil or placed in metal trays before putting them in the oven. The oven is then heated to 400 degrees Fahrenheit for 30 minutes or, alternatively, 325 degrees Fahrenheit for 2 hours.

 

6. Although ovens and microwaves have been used to sterilize instruments, probably the best way to guarantee sterility in an austere setting is a
. Hospitals use a type of pressure cooker called an autoclave that uses steam to clean instruments, surgical towels, bandages, and other items. All modern medical facilities clean their equipment with this device (I hope).

 

Having a pressure cooker as part of your supplies will allow you to approach the level of sterility required for minor surgical procedures. As you can imagine, this isn’t easy to lug from place to place, so it’s best for those who plan to stay in place in a disaster scenario.

 

Here’s a link to the procedure:

 

In most survival settings, “clean” may be as good as it gets, but is that so bad? Modern medical facilities have the ability to provide sterility, so there is very little research that compares clean vs. sterile technique.

 

In
, an experiment was conducted in which one group of patients had traumatic wounds that were cleaned with sterile saline solution, another group with tap water. Amazingly, the infection rate was 5.4% in the tap water group as opposed to 10.3% in the sterile saline group. Another study revealed no difference in infection rates in wounds treated in a sterile fashion as opposed to clean technique.

 

Therefore, clean, drinkable water is acceptable for general wound care in survival scenarios. That doesn’t mean that you shouldn’t use antiseptic solutions if you have them, especially for the first cleaning.

 

Disinfectants, Antiseptics, Antibiotics

 

 

So what’s the difference between a disinfectant, an antiseptic, a decontaminant, and an antibiotic?

 

To maintain a clean area, certain chemicals are used called “disinfectants”. Disinfectants are substances that are applied to non-living objects to destroy microbes. This would include surfaces where you would treat patients or prepare food. An example of a disinfectant would be bleach.

 

Disinfection removes bacteria, viruses, and other bugs and is sometimes considered the same as “decontamination”. Decontamination, however, may also include the removal of noxious toxins and could pertain to the elimination of chemicals or radiation. The removal of non-living toxins like radiation from a surface would, therefore, be decontamination but not necessarily disinfection.

 

While disinfectants kill bacteria and viruses on the surface of non-living tissue, “antiseptics” kill microbes on living tissue surfaces. Examples of antiseptics include
Chlorhexidine (Hibiclens), Iodine, and Benzalkonium Chloride (BZK).

 

Antibiotics
are able to destroy certain microorganisms that live inside the human body. These include drugs such as Amoxicillin, Doxycycline, Metronidazole, and many others.

 

Having disinfectants, antiseptics, antibiotics, and clean instruments will give the medic a head start on keeping it together, even if everything else falls apart.

The Final Word

 

 

Up until now, I have held off on adding anything but the most basic of medical instruments to my emergency kit. That has been foolhardy. Just last week, I spoke with someone whose son had a huge splinter embedded under his fingernail. In spite of his extreme pain, the 24 hour emergency clinic sent him away telling him to “see a doctor in the morning”.

 

If something like this happens in a survival situation, having a set of medical instruments along with a means to ensure they are sterilized will be important. Even without being in a survival situation, they are useful and can be put to good use..

 

At the end of the day, none of us know what our lives will be like down the road. The best we can do is prepare for the worst and hope we will never have to use our preps for survival purposes.

 

Enjoy your next adventure through common sense and thoughtful preparation!
