Ok, With arterial bleedng, its from a severed or knicked artery, and spurts bright red blood. The treatment for those is usually tournequet to controll bleeding. Then they need surgical intervention to repair the vessel. If you suture it, it will just bleed out internally.
As far as sutureing, by closing up a deep wound that isnt arterial bleed, It closes up the wound, and keeps the risk of infection down, and keeps the wound closed to keep it from being opened back up. Reduces scarring too. I dont care though, scars are cool! The sutures Ive seen done are usually bleeding minimally, not gushing, so bleeding has ben somewhat controlled.:thumbup:
Again, just my opinion, and how I observe, and take in the info that is thrown at me, I am not an expert.:thumbup:
