fuckin' lel, u cheeki /k/unt
FIRST fucking thing I wanna say is that I'm not a doctor. Take this for what it is, just some random faggot on the Internet telling you what he's read and/or been told. That out of the way, my first-echelon choices for minor shit in the field, personally, is either ordinary triple-antibiotic ointment like Neosporin (burger brand name, if you're not familiar), or the New-Skin shit I mentioned earlier, which contains... hang on... benzethonium chloride. Which of these I use is largely dictated by the size of the wound and the mechanism of wounding; they seem more or less equally effective in my experience. Although as I say that, it occurs to me to mention that New-Skin can be troublesome with young children in my experience; they seem prone to scratching it away if the wound itches, so bear that in mind if you're responsible for any larvae.
In a more settled setting, like at home for instance, my go-to is high-strength isopropyl, like 91%. Murders fucking everything, no prisoners. Hydrogen peroxide is pretty good, too, but I'm told by my ER nurse relative that it slows healing, and that the pros are moving away from it for this reason. She also recommended PVP-I, but research I conducted found an issue with certain pathogens actually being able to sort of hide out in the agent itself (guess my nurse hadn't got that memo yet), so I'd skip it for now.
As far as in vivo, you know about fish antibiotics, right?
Final note, I always try to stress in these sorts of conversations that I'm not, NOT a fucking professional, and I urge you to consult someone you trust who has actual, formal training and certs.
Based namefag is based, let's do it.
>i dont know whether its ok to just dump it in the wound
No, you don't wanna just dump that shit into the abdominal cavity or some shit. It's entire job is being universally toxic as shit; anything with a label saying stuff like "for external use only", you're gonna want to use carefully. I'm not qualified to advise you on how to, or indeed even whether or not to apply such agents to internal tissues; all I'll say is that by the time you have occasion to even contemplate any such action, it's time to just stop the bleeding as best you're able to and get your PT to actual fucking trauma care and let them deal with it. You or I have absolutely no business trying to sterilize deep tissue in the field, except maybe as a last-resort hail Mary when everything is fucked forever (EMP-level bullshit, for instance) and homie's definitely gonna die anyway if we don't do something.
