I cut my finger cooking last night, and apparently found a nice juicy vein in the process. I was in the middle of something time critical, so when I couldn’t find a band-aid, I did the ol scotch tape + paper towel approximation* and went back to what I was doing until I could reach a good stopping point.
At said stopping point, I looked at my finger, and then the floor, and apparently unbeknownst to me, I’d been bleeding profusely, and there was blood all over the kitchen floor, counter & spattered down my pant leg. At that point, I changed pants and ran to the grocery store for some proper band-aids. Once I got enough pressure on it to stop the bleeding** I mopped up. The place looked like I’d slaughtered a goat, though I couldn’t have lost more than an ounce or so of blood.
*Way back when i worked construction, I worked with a guy who would bind up wounds with any semi-clean absorbent material and duct tape. This works surprisingly well, better sometimes than band-aids or gauze+tape dressings. I suppose it’s preferable to use sterile dressings, but in the real world, a reasonably healthy individual will rarely get an infection in a cut allowed to bleed freely for a few seconds, and then bound tight enough to slow the bleeding down to an ooze. That’s why your blood is at a positive pressure gradient with respect to the outside world — so it comes out instead of letting germs in.
**I have to have a pretty bad cut to consider stitches, having wasted my time and money a couple times with ER visits. If you can stop the bleeding and you can’t see bone, carefully applied clean dressings usually do just as well. My last ER visit about a cut involved a broken olive oil bottle and looked like an improvised mouth 3 inches wide. I drove myself to the hospital with my right hand wrapped in a bloody towel. Good times.
