Skin Preps and Washes--When To Use Rubbing Alcohol, Betadine, Hibiclens, Peroxide, Etc., and Why

A lot of what I write about on Tuesdays concerns the supplies you want to have on hand to let a licensed professional care for your family should the need arise.  We see what has happened in the past when economies collapse or war breaks out, and we see what is happening in Venezuela right now.  They still have some physicians who haven't left the country, but supplies are virtually non-existent.

However, because we Americans have been taught that only physicians and nurses should be providing care for anything more serious than simple scrapes and common colds, many don't have a clear understanding of various supplies and their uses.  Today I want to focus on the different solutions used for cleaning skin and wounds.

Rubbing alcohol is used to disinfect instruments and skin and to make liniments.  It is commonly available in 50%, 70%, and 91% solutions. You must have a minimum of 70% for sterilization and disinfection.  And of course, 91% is dual purpose since it can also be used as a cooking fuel.  However, and it seems counterintuitive, a 70% solution is more effective at disinfecting than the 91% solution.  Water is needed to carry the alcohol into the bacteria to kill the bacteria.  A 91% solution of alcohol evaporates faster and has less water to carry the alcohol into the bacteria.  (And it's much more expensive.)  Alcohol does not inactivate some viruses (hydrophilic viruses like polio and Coxsackie).   Alcohol pads and hand sanitizer are generally 60-70% alcohol.

Rubbing alcohol should never be used in a wound, only around a wound for cleaning.  Using alcohol in a wound kills healthy cells and can delay or prevent healing.    Dr. Cynthia Koelker, author of Armageddon Medicine, recommends storing two 16-oz bottles of rubbing alcohol for a family. Store one box of 200 pads as well.

Hydrogen peroxide is commonly available in a 3% solution.  It is always in a brown bottle because it is degraded by light.  Even with being in a brown bottle, it still only has a six month shelf life once it's opened.  Hydrogen peroxide can be used to sterilize surgical tools and is effective against viruses, bacteria, and yeasts.  It is environmentally safe as it degrades to form oxygen and water.  It has historically been used for disinfecting wounds; it's been a staple of home first aid cabinets for years, and is still used in developing countries because it is cheap and readily available.  But it kills newly formed tissue and induces scarring.  It should never be used in a wound, only around a wound for cleaning.  For family medical preparedness purposes, Dr. Koelker advises storing one 16-oz bottle. 

Chlorhexidine (Hibiclens) is a disinfectant and antiseptic used to sterilize surgical tools and disinfect the skin before surgery.  It is on WHO's List of Essential Medicines and is available over-the-counter.  More effective than povidone iodine, and certainly more expensive, it is not effective against poliovirus or adenovirus.  It has recently started being used in poor countries for cleaning umbilical cords in newborns and has been shown to reduce the neonatal death rate by 12%.  Do not allow chlorhexidine to get into the ears as it can damage hearing.  One 16-oz bottle should be sufficient for family medical needs in a long-term collapse of society.

Povidone iodine (or iodopovidone, Betadine), most commonly available in a 10% solution, is used to disinfect the skin of the patient and the providers' hands prior to surgeries or procedures, and is also used to clean umbilical cords.  Like chlorhexidine, it is also on WHO's List of Essential Medicines and is available over the counter.  It is used to disinfect and clean around minor wounds, never in.    When diluted to 2.5% (one part of the 10% solution to three parts water), it can be used to disinfect medical instruments.  Instruments should soak for 15 minutes.  Some evidence suggests that alcohol and chlorhexidine are better than povidone iodine for pre-operative skin cleaning.

Povidone iodine is not to be used on burns or puncture wounds, nor is it to be used with people allergic to iodine or seafood.  In an emergency, an iodine wipe can be dropped into a bottle of water and used to make a disinfecting solution.  Store one 16-oz bottle per family or a box of 100 prep pads.

Benzalkonium chloride (BZK, BAK, BAC) is active against bacteria, some viruses, fungi, and, unlike all the other solutions, protozoa.  It is the preferred solution when dealing with animal bites as it has been shown effective against rabies.  (In an emergency, if you are dealing with an animal bite, drop a BZK wipe into a bottle of water to make a disinfecting solution.  Irrigate with this for ten minutes, and then irrigate with plain clean water.)  It is more effective than alcohol, doesn't dry out the skin like alcohol, and isn't messy like povidone iodine.  It's one of the active ingredients of Bactine.  Like all the other disinfecting solutions above, it is used for cleaning around a wound, never in.  It is ideal for prepping before inserting a catheter and the safest for using around the eyes, but should not be allowed to get into eyes.  It is available in wipes and is the skin prep of choice for wounds received in water because it will kill protozoa.  Larger groups may include a box of BZK wipes in their supplies.  In our family, we all carry two BZK wipes in our boo-boo kits; more in the larger kits.

Clean water is actually one of the best things for irrigating a wound and removing debris.  However, irrigating does not mean pouring water over or swishing in a basin.  Irrigating a wound is done with decent water pressure that is achieved using a needle-less syringe, a water bladder, or a peri bottle (like those the hospital sends home with new mothers).

Sterile saline is used for irrigating debris out of the eyes and irrigating and washing wounds around the eyes.

Dakin's solution.  Dakin's solution was developed during WWI as a wound antiseptic.  It is used to kill germs and prevent growth of germs in wounds.  It is an excellent solution for irrigating wounds without killing healthy tissue.  It is very inexpensive and easy to make, and thus ideally suited for the difficult circumstances a collapsed society will present. 

To make your own, you will need:
Sterile equipment--pan and lid, glass jar(s) and tight-fitting lid(s), measuring cups and spoons
32 oz clean water
1/2 teaspoon baking soda
Regular, unscented, not concentrated or ultra, just regular bleach in one of the following concentrations:

full strength--3 ounces (95 ml) bleach--for sterilizing instruments
1/2 strength--3 tablespoons plus 1 teaspoon (48 ml) bleach--for debridement of necrotized wounds
1/4 strength--1 tablespoon plus 2 teaspoons (24 ml) bleach--for irrigating wounds
1/8 strength--2 1/2 teaspoons (12 ml) bleach

Boil water for 15 minutes with the lid on the pan.  Remove from heat.  Add the baking soda to the boiled water.  Measure bleach according to desired strength and add to water.  Cover tightly in a glass jar and wrap jar in aluminum foil to shield it from light.  (Do not store Dakin's solution in metal containers.)  Once opened for use it is good only for 48 hours.  Discard unused portion.  Unopened and protected from light, the solution can be stored for one month at room temperature.

Label the jar with the date and time you made the solution, as well as the date to discard it.

The full-strength solution is used only on stainless steel medical instruments.  Dakin's solution will corrode nickel, chromium steel, iron, and other metals.  Because of its corrosive nature, instruments should not be in the bath solution for longer than 30 minutes. 

Use only 1/4 strength solution for acute wound irrigation.  Always irrigate very generously with plain water following irrigation with Dakin's solution.  If the solution is used for mouth wash, do not swallow it. Do not use in individuals allergic to any of the ingredients.
