DC; sorry, cara mia, but you are dead wrong on this one.
Using isopropanol or similar chemicals on a wound is extremely harmful, would qualify as malpractice if done by a medical practitioner. I would be glad to testify against you in court if you did it to one of my patients.
Howard, I also believe in treating both the spirit and the body. To do so by inflicting needless pain, intentionally, is abhorrent. Frankly, I would have reported you to Child Protective Services. The general golden rule in medicine is that you and the patient are on the same side. To do something punative is NOT being on the same side.
Now, with this out of my system, let me explain about the dangers of plantar (sole of the foot) injuries. First of all, unlike the hapless lad in question, they tend to be punctures. This takes a bunch of nasty things down under the skin where you can't wash them out. The worse cases are where a kid is wearing tennis shoes, and a small plug of the inner sole of the shoe gets under the skin. This is usually loaded with pseudomonas, a tough bug to treat.
We routinely numbed up and explored and vigorously irrigated plantar p.w.'s. Even so, there was a high infection rate. Pseudomonas still often requires IV antibiotics.
One rarely sees damage to significant structures on the sole of the foot; i.e. the concerns about tenon laceration is vastly different from the hand, where it is seen routinely, as opposed to the foot, where tendon damage is rarely seen.
This is due to the plantar fat pad, the 'cushion' of the foot. It protects the tendons from most injuries. It also makes extremely frustrating the search for foreign bodies. I had to, on more than one occasion,
resort to fluoroscopy to remove needles from the foot.
Best thing for would cleansing? I would mix a small dab of dishwashing detergent (this is optional) with Betadine solution in a 1 part Betadine solution, 9 parts water mixture. This avoids the cytotoxic effect of straight Betadine. If you happen to have some hydrogen peroxide, this works well also, the foam tends to flush out the debris. Of course you don't mix Iodine with peroxides, or you end up with the reduced form of Iodine, iodide (like in potassium iodide). This has no anti bacterial effect.
Best thing to carry? Betadine solution. Excellent wound cleanser as mentioned above, and also great water purification at 10 drops per liter.
To summarize: be very very careful and cautious about plantar injuries, especially puncture wounds. There is no such thing as a minor hand or foot laceration. Trust me on this, I have learned from hard experience.
Inflicting needless pain on a minor patient to teach him or her a lesson is child abuse. (I know, the kid was probably laughing his head off, and no real harm done, but there is a different climate present in the medical community today, so watch yourself, OK?)
