During Lister’s early days as a surgeon, silk ligatures were used. Their ends were left outside the wound until the surgeon could pull them out. This system was not good.
Lister knew that the human body could absorb foreign particles. He wondered whether antiseptic silk might be absorbed too.
In 1867, he made the first experiment. The patient was an old horse. Lister cut open the horse’s neck and tied a silk signature around an artery. He sewed up the opening. One stormy night many years later when Lister was in bed with the flu he learned that the horse was dying. Lister rushed to the stable and by the light of a lantern he opened up the neck of the horse. He saw what he had hoped to see: the silk had been neatly walled off by surrounding tissue. Now he knew that it was no longer necessary to remove the ligatures used inside the body.
