Everything you always wanted to know about the history of healthcare, but were too afraid to ask is a book about development of medicine. Two hundred years ago operations were very painful, the patient, who was undergoing a surgery, suffered a lot. People tried to anaesthetize with alcohol, which was dangerous, because it increases bleeding. The first anaesthesia was nitrous oxide, now called laughing gas. It was believed, that this substance is harmful for people, but H. David discovered that it is untrue.
People started to use nitrous oxide as an anaesthesia after Horace Wells discovered its qualities. He went to a show, where that substance was presented. During the performance one man got seriously hurt, but felt no pain. He was very surprised, that such an accident happened to him. After that discovery Horace Wells, who was a dentist, tried to use it during taking patient’s tooth out. It wasn’t successful, because he didn’t use sufficient amount of nitrous oxide.
