Once upon a time while camping I was helping to saw logs for the fire. I was holding, and someone else was sawing. The saw jumped out of the groove and sliced across my right index finger between the knuckle and the next joint.
Oooo! Neat! look at all the layers…!
Well, there a lot of screaming and hollering following that, most of it not mine. The scout leader already had some boiling water available, let it cool down, then sat me down and used about a gallon of it to wash the cut out. It was bloody, but no spurting and I didn’t feel faint or anything…
Anyhow, there was a lively debate about stitching me up and offerings of sewing kits, but the woman in charge said no, we’re not going to do that. After the wound was clean she lined up the edges of skin and put on a firm but not squeezy-tight bandage. And that’s what I had until we got back to civilization.
Well, mom freaks and takes me to a doctor. And the doc says… “Hmmm… no infection… wound is closed… yeah, it’s a bad cut and I might have stitched it when it happened, but no need to do so now, it’s already half-healed”. So, no stitches. And almost no scar – you wouldn’t notice it unless I point it out, and even then it’s hard to see. Then again, I was young and I don’t scar much anyhow.
So, methinks keeping the wound clean to prevent infection is probably the most important thing. The stiches can pull the edges together, but so can other means.
Having had an abcess later in life that did require surgery, I think I’d prefer to keep a wound open, clean, drained, and uninfected and ask a plastic surgeon to “revise” the resulting scar later than to sew it up and have an abcess form - particularly if I’m away from modern medical care.
