Little Johnny rushes inside, out of breath and shouts, "Mother! Mother! Give me some money for the poor old man that's shouting along the road!"
His mother replies, "What is he shouting?"
"Ice creams! Come get your ice cream..."
Lister disinfectant useIn 1865, Dr. Joseph Lister became the first surgeon perform an antiseptic operation by liberal use of carbolic acid (phenol) as a disinfectant. He hadstudied Louis Pasteur's germ theory of disease, that infections are caused by bacteria.Lister knew carbolic acid had been effective in municipal use for treating sewage, and decided to try using it to kill germs that would otherwise infect wounds.He poured it on bandages, ligatures, instruments and directly on the wound and hands. His first patient to benefit from this procedure was James Greenlees, age 12, whose broken leg was treated after being run over by a cart. The dressing was soaked with carbolic acid and linseed oil. The wound healed without infection. Lister continued his protocol of hygiene, and reduced the surgical death rate from 45% to 15%.« |
