I can't remember if it was mentioned in all honesty. There's no real reason that the incision need get infected if they were very careful.<p>If I remember correctly the medic sterilized his instruments, himself and the patient with alcohol or some sort of solvent.<p>I have a friend who lived in the Yukon (north edge of Canada) for many years. He slashed his leg open with a knife accidentally while working one day, but he was a day or so away from medical care. He just cleaned it and then sutured himself up using a needle and dental floss. He eventually got to a hospital, the doctor told him he had done just fine!
