History of Healthcare

1. History of Healthcare Objectives: You Will Be Able to Identify at Least 10 Discoveries/inventions in Health Care and Describe Several Advances in Different Time Periods

2. Question • How many of you have ever been in the hospital and had an IV? (Put your head down) • How many of you were born by c-section?(Put your head down) • How many of you have taken antibiotics?(Put your head down) • Now look around, if this had been 100 years ago, chances are that at least ½ of you would have died!

3. Advances in Healthcare • Due to advances in medicine and technology in healthcare we can now treat many of the diseases that formerly would have been fatal. • We are going to study advances that have occurred since primitive man. Understanding the hardships that went along with the discoveries can help us appreciate the advances in healthcare in the past 5000 years!

4. Early Beginnings Primitive Man

5. What Was It Like? • No electricity, few tools, and poor shelter • Time was spent protecting themselves against predators and finding food • They were superstitious, they believed in witch doctors • They used herbs and plants as medicines, some are still used today!!!!

Medicines • Digitalis – from foxglove plant – used to strengthen and slow the heartbeat • Quinine – from the bark of the cinchona tree – controls fever, muscle spasms and helps malaria • Belladonna & atropine – made from the poisonous nightshade plant – they relieve muscle spasms, especially in GI pain

7. More Early Medicines • Morphine – made from the opium poppy – relieves severe pain and is addicting

8. Ancient Times Egyptians

9. What Did They Do? • They kept accurate records • They were superstitious • They learned to identify certain diseases, used medicines to heal disease • They used the art of splinting fractures

10. Chinese

11. What did they do? • They did not believe in dissection of the body, so this limited what they could learn • They believed in treating the whole body by curing the spirit, this was early “holistic care” • Holistic care is treating the mind, body and soul, this is the trend in today’s healthcare

29. 19th and 20th centuries Organized advancement of medical science

30. Important Discoveries & Inventions • Ignaz Semmelweiss – established that handwashing with chlorinated water was effective in protecting against the spread of disease • Louis Pasteur – discovered that microorganisms were everywhere and that they caused disease, he created pasteurization, he developed a vaccine for rabies

31. Inventions and Discoveries • Joseph Lister – he began to use carbolic acid on wounds to kill germs and prevent infections, he became the first doctor to use antiseptics during surgery • Ernst von Bergmann – Developed asepsis • Robert Koch – known as “Father of Microbiology” discovered many disease causing organisms • Wilhelm Roentgen – discovered x-rays in 1895

32. More Inventions and Discoveries • Paul Ehrlich – discovered the effects of medicine on germs, discovered a treatment for syphilis after 605 experiments • Gerhard Domagk – discovered sulphonamide drugs • Ivanovski – Russian scientist who discovered that some microorganisms were too small to be seen with a regular microscope, he called them viruses

33. Even More Discoveries • Sigmund Freud – discovered that the mind has a conscious and unconscious realm, his studies are the basis for psychology and psychiatry • 1928 Alexander Fleming – discovered penicillin • Jonas Salk – discovered a vaccine against the polio virus
