The Gaper

No, not someone who gapes, often with a dumb look on his or her face, but a wound, typically a laceration, that gapes open after being cleaned (with pressure irrigation). In the wild med biz, there has been a sort-of guideline stating a wound that gapes open more than one-half inch is best treated by being pulled closed and held in place with wound closure strips or improvised strips (say, from tape). There has been the birth of a new guideline: If the wound gapes open after cleaning, consider closing it with . . . well, you know the rest. If the wound has been well cleaned, there are several healthy reasons, way out there, to close it. It's more comforting to most patients, it usually heals better with less scarring, and it may reduce the chance of infection (since you have "closed the open door" that invites germs in).

Snakes Again and Again

With the season of the serpent well upon us, a couple of interesting (I thought) snake questions recently appeared on my screen. The first reader wondered if it was true that a pit viper will bite itself in order to kill itself if it knows it's dying anyway. People who know snakes much better than I do say "no," and, in fact, state that poisonous snakes are immune to their own specific venom. So, there you go. The second reader asked if putting kerosene on pit viper bites would help. Well, that theory goes back a long way, at least more than a century in U. S. where rural dwellers soaked snakebitten extremities in kerosene and didn't die. But so few people die from poisonous snakebite in the U.S. anyway, almost always less than 10 deaths a year from thousands of bites in recent decades, the I-tried-it-and-it-worked theory is useless. And, again, the experts are pretty sure, based on science, that a kerosene-soaked snakebite, although it wouldn't hurt, wouldn't help.
