I've purchased it online, and used it on myself, friends, etc.. I have like a field surgical kit type deal, solely for personal use. I avoid seeking higher care at all costs. It burns. Badly. Apply ice, and it comes apart, so in a rural setting if you're lacking a doctor... Go to the Vet, they can usually do a good job. Never had a problem, yet. Antibiotics? Call up and ask for oral liquids for a cat, usually get that bubblegum flavored pink stuff. Totally serious. Being a technical rescuer, wilderness rescue, I would never seal a wound. There is nothing sterile in the middle of the woods, I carry stuff to irrigate; and benzoin tincture, steri-strips, etc.. That Band-Aid stuff in the tube, with the foam applicator does just as good of job. But I'd never seal a patients laceration. Irrigate it well, perhaps mixing betadine w/ water, dress it, and wrap it w/ coban. Never seal it, any more than you have to, if it's big... Slap a QuikClot on it and hope for the best.
I can say, that dermabond, when allowed to dry and not move the area, does heal quite well. I was hanging a light fixture in the EMS supply room, sat the drill down, and my hand ever so gently rubbed the bit. Nice, kinda deep, 1.5" lac from my back of my thumb, across the side of my wrist. There's a vein there. Bloody fricken mess, but you can only tell where the lac was, b/c my wrist, yanno, bends. Just like a 1/4" spot where there is an obvious scar. As nice as that is to have on the spot, and not take 4 hours to go to the ER... However.
I don't think that it has a place in EMS. We're not even allowed to carry first aid cream. At least if it gets sealed up, then turns into an abscess, they won't be suing EMS. We don't get a lot of BS calls in the minor injury department, ppl out here tend to be able to take care of themselves a little better. First Aid Kit rant... Honestly, have any of you bought a first aid kit recently? We have one in the kitchen, from Target. It looked neat, that's the only reason, it looks cool in our 1940's looking kitchen. There's nothing in it to treat anything larger than a paper-cut, or a hangover. Maybe a broken finger. Sorry to go off topic, Oxycontin on board, I have 45min CPR cramps.
