Having been involved in medicine for 30 years (a lot of it smash and trash) I have gone quite minimalist and keep most of my IFAK between my ears. I have an external “pouch” on my range pack that could easily be stuffed into a cargo pocket on a pair of camies and when I hunt that is exactly where it goes. 50% of the stuff is for “Oh $h!t’s” and 50% is for the stuff you actually run into.
@WildRose has it right with the Trauma shears, Israeli Dressings and tourniquet (I will add, get the tourniquet with the ALUMINUM windlass, I have scars on my hands/wrists from breaking the poly ones)
Other handy bits and why:
-Tampon’s X2: Not only for their original intended purpose. They are FANTASTIC for long lacerations or bullet holes in meaty parts (don’t stick one in somebody’s chest or belly!)
-Roller Gauze X1: Handy as He!! for just wrapping stuff up and or using the first couple feet as packing.
-Tape X1: I like silk tape, paper tape is worthless. Vinyl electrical tape is another excellent option as is duct tape.
-Band-Aids: Put a box of assorted sizes and types in a ziplock sammich bag or similar.
-Mole Skin: A 4’ x 4" square: Blisters suck.
Put these in a zip lock together:
-Hand Cleaning Wipes X5: Like you get at a Rib or Sea Food joint, good general cleaning.
-Alcohol Pads X5: Great pre Band-Aid application prep and it also gets the oils off YOUR fingers so the band-aids stick.
-Betadine Wipes X5: Good GP anti-infective
Put these in a DOUBLE zip-lock baggy
-Tech-Nu X5: Poison Ivy, Oak, Sumac etc. lotion
-Burn Gel X5: for burns
-Bacitracin/Triple ABX ointment: Squeeze pouches if you can get them tube if you can’t
-Tweezers with the magnifying glass: for splinters and such
-Hemostats (Actually I prefer needle drivers but that’s me) great for getting an ear plug out of an ear when shoved in too deep and other uses.
-Knife: You should already have one on but get a 1 1/2" Key chain knife with a “long pointy tip” sometimes you have to go digging for those splinters. If nothing else those key chain knives are sharp at least once. They are also handy for “drilling” a smashed finger nail.
-Light: White is preferred (Blue in a tactical situation) those little LED squeeze lights last forever and even more so if you leave the battery shield in place till you need it.
-Finger Nail Clippers: A split nail hurts
I have some other bits that I keep but they are kinda sketchy and not for regular public consumption.
