1. How did the introduction of anesthesia change medicine?
Before anesthesia, patients undergoing painful treatment had to simply bear the experience and were thus wary to have such procedures done because they would hurt so bad. After anesthesia became commonly accepted, it became more accepted to have more invasive treatments done, leading to an increase in the health and quality of life of the general population.
2. What role did anethesia play in the growth of modern hospitals?
Before less painful surgery could be performed, there were simply less surgeries. But as surgery became more commonplace, doctors realized that opening the body made it vulnerable to infection. Thus they needed a cleaner environment to practice their trade. As more surgeries were performed, and more of them in hospitals, hospitals became cleaner and more professional environments to practice medicine.
