CA brings to your attention a post at American Partisan, referencing the utility of Dakin's Solution for wound cleansing.
As far as it goes, good stuff. Go read it.
We take the opportunity to amplify some under-emphasized points from that information.
1) Note the recommendation for making up over 2 gallons for "large or dirty wounds". This is not something you will be whipping up in a canteen cup over a campfire. You're going to need a dedicated facility adequate to the task.
2) The recipe for saline is adding 9 grams of salt to 1 Liter of boiled (and cooled) water. (For countries that have landed on the moon, that would be 1.2 ounces of salt per gallon.) All Dakin's adds is diluted hypochlorous acid, formed by the chlorine in the bleach, which does the actual business of germ-killing, plus a tad of baking soda to buffer the solution.
3) Anyone using isopropyl alcohol for wound cleansing is going to be rewarded by getting punched in the face by the patient. Hydrogen peroxide isn't much better. This is because both hurt like hell, because they're killing healthy, vital tissue. Wound debridement is trying to remove dead tissue and kill the germs growing on it from a wound. Creating more dead cells isn't going to help. And it will get you socked. (Moonshine, etc.: See above. The same is true for using just about anything not intended to clean and disinfect wounds.) Alcohol and peroxide are for cleaning fabrics, surfaces, and instruments, not the inside of patients. While they're better than rubbing dog crap into the wound, they're not better than nothing, or plain clean water. They're just better than dog crap. Don't use them for things you shouldn't be.
4) The average wound will require redressing at minimum of once daily (more frequently if dressings become saturated, dirty, etc.), for 7-21 days. Note that's per wound. So that box of 12, or even 100 4x4s isn't going to go very far. Start thinking of supplies in terms of case lots, not boxes.
5) Read the comments. Particularly illuminating is one by retired orthopedic surgeon Dr. "Hubbs". Read it all, to get an idea of what was required for him to repair one single hand laceration with a severed tendon. That's coming from a guy with four years of specific medical training after college, than another four or more years of orthopedic and surgical residency in that field, then a lifetime's worth of practical experience. You will not be doing that without that c.v. At least, not successfully. And note that he required things you can't get at Target, WallyMart, or on Amazon. Most of them are getable, but only with some diligent effort. That's before you ever learn how to use those supplies and tools. Followed by 5 weeks to recuperate. We repeat: Five. Weeks.
TL;DR answer: make friends with someone(s) with professional licensure, and a handy DEA control number.
Pro tools require pro skills and pro levels of supply.
Amateur Hour is a yuuuuuugely distant second choice.
Either option can result in death.
Which is going to cut into your tribe's talent pool rather harshly.
If you're going to do medical care, you have to do it correctly every single time.
Do, or do not; there is no try.
Your alternative is to half-ass it, and get the results one would expect from that COA.
