What will happen if (or rather, when) an even more dangerous organism appears

To a colleague in Wurzburg he wrote, "Should you, Herr Hofrath, without having disproved my doctrine, continue to teach your pupils [against it], I declare before God and the world that you are a murderer and the 'History of Childbed Fever' would not be unjust to you if it memorialized you as a medical Nero." His own staff turned against him. In Pest, where he relocated after losing his post in Vienna, he would stand next to the sink and berate anyone who forgot to scrub his or her hands. People began to purposely evade, sometimes even sabotage, his hand-washing regimen. Semmelweis was a genius, but he was also a lunatic, and that made him a failed genius. It was another twenty years before Joseph Lister offered his clearer, more persuasive, and more respectful plea for antisepsis in surgery in the British medical journal Lancet.One hundred and forty years of doctors' plagues later, however, you have to wonder whether what's needed to stop them is precisely a lunatic. Consider what Yokoe and Marino are up against. No part of human skin is spared from bacteria. Bacterial counts on the hands range from five thousand to five million colony-forming units per square centimeter. The hair, underarms, and groin harbor greater concentrations. On the hands, deep skin crevices trap 10 to 20 percent of the flora, making removal difficult, even with scrubbing, and sterilization impossible. The worst place is under the fingernails. Hence the recent CDC guidelines requiring hospital personnel to keep their nails trimmed to less than a quarter of an inch and to remove artificial nails.Plain soaps do, at best, a middling job of disinfecting. Their detergents remove loose dirt and grime, but fifteen seconds of washing reduces bacterial counts by only about an order of magnitude. Semmelweis recognized that ordinary soap was not enough and used a chlorine solution to achieve disinfection. Today's antibacterial soaps contain chemicals such as chlorhexidine to disrupt microbial membranes and proteins. Even with the right soap, however, proper hand washing requires a strict procedure. Canada Goose Chilliwack First, you must remove your watch, rings, and other jewelry (which are notorious for trapping bacteria). Next, you wet your hands in warm tap water. Dispense the soap and lather all surfaces, including the lower one-third of the arms, for the full duration recommended by the manufacturer (usually fifteen to thirty seconds). Rinse off for thirty full seconds. Dry completely with a clean, disposable towel. Then use the towel to turn the tap of. Repeat after any new contact with a patient.Almost no one adheres to this procedure. It seems impossible. On morning rounds, our residents check in on twenty patients in an hour. The nurses in our intensive care units typically have a similar number of contacts with patients requiring hand washing in between. Even if you get the whole cleansing process down to a minute per patient, that's still a third of staff time spent just washing hands. Such frequent hand washing can also irritate the skin, which can produce a dermatitis, which itself increases bacterial counts.Less irritating than soap, alcohol rinses and gels have been in use in Europe for almost two decades but for some reason only recently caught on in the United States. They take far less time to use -- only about fifteen seconds or so to rub a gel over the hands and fingers and let it air-dry. Dispensers can be put at the bedside more easily than a sink. And at alcohol concentrations of 50 to 95 percent, they are more effective at killing organisms, too. (Interestingly, pure alcohol is not as effective -- at least some water is required to denature microbial proteins.)Still, it took Yokoe over a year to get our staff to accept the 60 percent alcohol gel we have recently adopted. Its introduction was first blocked because of the staff's fears that it would produce noxious building air. (It didn't.) Next came worries that, despite evidence to the contrary, it would be more irritating to the skin. So a product with aloe was brought in. People complained about the smell. So the aloe was taken out.
