1 Medical Technology The Good, The Bad, and the Ugly

2 Warm Up How can technological advancements in medicine be both beneficial and harmful to society?

3 The Good During the 19th century medicine made great advances: Louis Pasteur ( ) proved that microscopic organisms caused disease. Once doctors knew what caused disease they made rapid headway in finding cures or prevention. Surgery was greatly improved by the discovery of Anesthetics. As early as 1799 the inventor Humphrey Davy ( ) realized that inhaling ether relieved pain. In 1846 the ether was used in almost every operating room as an anesthetic by surgeons to relieve pain during surgery.

4 The Good cont In 1865 Joseph Lister ( ) discovered antiseptic surgery, which enabled surgeons to perform many more complicated operations. Lister prevented infection by spraying carbolic acid over the patient during surgery. German surgeons improved on Lister s methods by using super heated steam to sterilize not only the operating room, but themselves as well. Rubber gloves were first used in surgery in 1890.

5 The Good cont 1947 Cardiac Defibrillation: A Cleveland cardiovascular surgeon, Claude Beck, successfully defibrillated the heart of a 14-year-old boy during cardiac surgery, bringing an apparently dead person back to life. A jolt of electricity is shot towards the heart to start it up again. This invention has saved hundreds of thousands of lives Commercial Ultrasound: A device which lets doctors and patients see and monitor a baby s health while still inside the womb Human Genome: The complete draft of the Human genome allows scientists and doctors to detect patterns and prevent diseases within patients.

6 The Bad/Ugly: Unit 731 Unit 731 and Unit 100 were the two biological warfare research centers set up in spite of the Geneva Protocol of 1925 banning biological and chemical warfare. Japanese researchers working at Unit 731's headquarters in Harbin infected live human beings with diseases such as the plague and anthrax and then eviscerated (cut open) them without anesthesia to see how the diseases affected human organs. (Summarize)

7 Quote from an actual surgeon! "The fellow knew that it was over for him, and so he didn't struggle when they led him into the room and tied him down. But when I picked up the scalpel, that's when he began screaming. I cut him open from the chest to the stomach, and he screamed terribly, and his face was all twisted in agony. He made this unimaginable sound, he was screaming so horribly. But then finally he stopped. This was all in a day's work for the surgeons, but it really left an impression on me because it was my first time.

8 Unit 731 Since the Japanese army used poison gas during the war, one of the Unit 731 s mission was to develop a more potent poison gas, thus prisoners were subjected to poisoning. At least 3,000 people, not just Chinese but also Russians, Mongolians and Koreans, died from the experiments performed by Unit 731 between 1939 and No prisoner came out alive of the Unit s gates. During the war, the Japanese Imperial Army used biological weapons developed and manufactured by Unit 731's laboratory in Harbin throughout China, killing or injuring an estimated 300,000 people. Because of the Unit s secret nature, there is no complete list of the experiments that were undertaken by Unit 731

10 Unit 731 They also wanted to test the limits of the human body, so they would run tests such as: Leaving a person outside in the freezing cold, wet, in order to see how long the body can last before freezing to death. Placing immense pressure and weight on a patient s back to see how much the spine can tolerate before breaking. The results for these tests were then used to ensure Japanese soldiers could be pushed to their limit, but not be pushed too far.

12 Give one-get One Write down your Haiku on a small piece of paper Get up and and read your haiku with the first person you meet eye contact with. Then exchange Haikus and find a new partner. Repeat the process. By the end of activity you should have heard at least 4 haikus and exchanged at least 4 haikus.
