 Today, we're going to be talking about hand washing. Why are we doing that? Well, it turns out these hands are really amazingly efficient and transmitting most of the common infections we see in children and adults. So you do not need antibacterial soap. The temperature of the water doesn't matter. It needs to be 20 seconds. It's a matter of just getting the surfactants, the soap, making sure that you've lifted all the bacteria off the skin. Like when you wash your clothes, you can't wash your clothes for 10 seconds. You'll wash your clothes for a while in the soap. So the soap particles lift the dirt off. In the hospital, we are maniacal about hand washing. You have to wash your hands before entering a room. You must wash your hands after leaving the room. You know, all of the disciplines teach hand washing to be honest with you. So the surgeons and the obstetricians have formal hand washing programs for how you wash your hands before entering the operating room because that's such a high risk situation to go in there with dirty hands. Voila, wonderful hands.
