I've owned a number of portable med kits. Ironically, the best one I've found for a compact kit is an old laptop bag I got at a thrift store for $5 that I cut the internal straps from to allow it to splay open flat. I have a full sized Iron Duck kit with everything up to first-line drugs and chest tubes + Heimlich valves. But seeing as it's probably $20k+ worth of supplies, it stays locked in the home except for road trips or range days, when it goes in the trunk. For my smaller kit that stays in my trunk I have:
Small pouch
PPE (N95 mask, nitrile gloves)
CAT Tourniquet
Quikclot Z-folds
Decompression kit (Clorhexidine scrub pad, 14g IV catheters, 3-way stopcock valves, Durapore tape)
Gauze (rolled and loose)
Coban roll
Trauma shears & gauze shears
10cc saline flushes
Hemostat & tweezers
Bulk sterile military gauze dressing (for open abdominal wounds/eviscerations)
NPA + Surgilube
Sharpie
Large pouch:
Hyfins chest seals
Bolin chest seals
Asherman chest seal
4x5.5in. Opsites (for chest seal)
6x8in. Tegaderm (for chest seal)
Various IV's (14-24g + plugs + lines + tape + tourniquets + alcohol swabs)
1l Saline
0.5l Ringer's lactate
SAM splint + wrap
Various Naloxone kits (0.4mg/ml MDV + 2mg/ml pre loaded syringes + IM syringes + tourniquet + alcohol swabs)
Stethoscope
Outside pouch:
Heat blanket
MRE heaters
Chemlights (white, high intensity)
Cravats
I live in a very murdery, heroin infested place, hence the abundance of chest seals and Narcan. I could bring back 6 heavy-duty OD's @ 2mg's naloxone each and treat ~20 individual thoracic wounds with just what is in the smaller kit. With my full kit I can do much more, including crich's, chest tubes, cardiac arrests and intubations (though no RSI drugs anymore
). But I would be heartbroken to have it stolen from my trunk, so it stays at home except for certain occasions.
