Ok... Assuming this is not a clean knife wound, but rather a traumatic laceration without clean edges, and intrusion of particulate and possible other foreign matter. Basing on a 6" long x 1-2" deep thigh laceration with no arterial, venous, ligament or tendon involvement - based on the above- time is not critical, this is a semi-secured area .
a. Stuff:
1. What is the availability of potable water? What is the availability of any water? If potable water is plentiful boil it for 2 minutes, just for safety's sake, cool it to just about body temp. If the water is suspect - filter through cloth (multiple layers) to remove sediment, then boil vigorously for a minimum of 8 minutes, and cool to just above body temp. (unless you're like me and keep a couple of bottles of sterile water in your med kit) make sure you have at least 1.5 gallon of water.
2. Got a turkey baster? got a Garlic injector? Got a soft toothbrush? tweezers? long needles? got a good sized bowl or two? Boil them separately from the water to be used for the actual cleaning.
3.. How well stocked is your home? (I personally keep betadine around, but that's me) No accdess to betadine or one of the other surgical scrubs or iodiform antiseptics... Dishwashing detergent, antibacterial soap, any soap you have on hand...
4. Towels, washcloths, clean rags...
5. More bandages, and preparation to control bleeding again - a good cleaning WILL restart bleeding.
b. Procedure:
*****THOUROUGHLY WASH YOUR HANDS - TWICE - NO, MAKE THAT THREE TIMES - UNDER YOUR NAILS, UP TO YOUR ELBOWS -REALLY CLEAN - AND GLOVE UP IF YOU HAVE THEM.*****
1. gather clean materials, one towel underneath the area to be scrubbed - you need to create a clean (not sterile) field to work.
2. fill one bowl with clean water, fill one bowl with clean soapy water, keep remainder available. If you are using betadine in the water, 1 oz betadine to a quart of water should be sufficient - if you are worried about the cleanliness of the water go to 2 oz/qt. If all you have is soap - a good sudsy mixture is all you need - about 1-2 tbsp per qt of water
3. with a clean soapy washcloth(not too wet) wash surface area- at least 6" out from the wound edges - to keep from reintroducing junk into the wound. Do not put this back into your clean soapy water
4. with a clean damp washcloth, rinse/wipe any soapy water from your clean field.
5, Really Inspect the wound, look for debris, and matter, anything that looks like it's not just plain meat (because there's no other involvement at the moment does not mean you're not close) - that's the first stuff that needs to be removed.
5.a. Remember that turkey baster or garlic injector? fill it with either the plain clean water or the clean soapy water - irrigate, put some force into the water stream, to help dislodge junk using gravity to help flush the wound.
5.b. repeat step 5.a.
6. there are a few large pieces of junk still in the wound, nothing shiny (tendons,ligaments, bones), pulsing or veiny looking - it's a deep meat cut.... using your tweezers or sharp needles pick those large pieces out - can't get them? dunk the soft toothbrush in the clean soapy water and gently scrub them loose.
note- the above and below will restart bleeding - this is good, helps flush the wound - we won't try to recontrol immediately, unless it becomes a major torrent.
7. still got your toothbrush? good, lightly scrub the entire wound. Grab your turkey baster and fill with clean water - irrigate
8. Irrigate some more
9. irrigate a little more
10. dry the area.
11. inspect the wound - what do the edges look like - clean, jagged, what? this is going to get you to the bandaging.
recontrol bleeding at this time - the wound should be clean.
wound closure/Bandaging - depends on your materials - based on the description of the wound - sutures would be optimum closure - but I think butterfly closures / steristrips would be easier/faster/less traumatic to both parties involved. (Assuming fairly clean edges to the wound) -starting at the top of the wound one sticky side of the butterfly 'wings' on one side of the wound and pull that to the other edge of the wound, keep the edges together, no puckering or overlap - hold together, place other sticky side on the other side of the wound - repeat every inch or closer if you can - make more butterflies from surgical tape if you can. When finished - spay with nu-skin if you have it. the bleeding should be controlled - so wrap loosely to protect the wound if the person doesn't have to move for a while - if you have to move out, bandage snugly but not tightly.
Check the wound on a regular basis - 2x a day minimum, to see if any signs of infection appear.
This was probably more than you wanted, but hey, you asked.
