The top 10 advances in healthcare have changed and will continue to change the world in many ways.
1. Vaccines
Vaccines – it is one of the most effective ways to fight rampant viral infections. Ge Jing, Department of Obstetrics and Gynecology, The First Affiliated Hospital of the General Hospital of the Chinese People’s Liberation Army
In 1796, Dr. Edward Kornai first proposed the idea of vaccines. In 1796, Dr. Edward Hornet first came up with the idea of a vaccine, which he used to successfully make an English boy immune to smallpox.
In 1796, Dr. Edward Corner first came up with the idea of a vaccine that successfully immunized an English boy against smallpox. The concept of vaccine was further promoted by scientists such as Louis Pasteur. In modern history, large numbers of soldiers in World War I and World War II were vaccinated and successfully fought off diseases such as tetanus, diphtheria and typhus.
The polio vaccine had quite an impact. From a global health perspective, the smallpox vaccine invented by Jenner may have had a greater impact in terms of lives saved.
2. Surgical anesthetics and disinfection
On October 16, 1846, things changed. William T.C. Morton demonstrated the miraculous effects of ether – a substance sufficient to relieve the pain long caused by surgical procedures.
While anesthetics themselves were a tremendous advance, another advance that emerged around the same time that may have been more useful than anesthetics was sterilization – the creation of a sterile environment for surgical procedures.
Surgery without sterilization would have killed the patient.
3. Improvements in water purification and sanitation
Compared to advances in surgery and other cutting-edge technologies, public health measures may seem unnoticeable. But the fact is that since the spread of clean water and good sanitation in the 19th and 20th centuries, millions, if not hundreds of millions of lives may have been saved.
In the past, 15 percent of babies died prematurely, and the biggest cause was dysentery caused by unclean drinking water and milk.
Water purification and public sanitation measures have greatly reduced the incidence of deadly diseases like cholera transmitted by drinking water, and improvements in sanitation have greatly reduced the health impact of parasitic infections.
4. Antibiotics and antiviral drugs
Like vaccines, the advent of antibiotics has ushered in a new era in the treatment of transmissible diseases. It is interesting to note that antibiotics were discovered inadvertently. In 1928, Sir Alexander Fleming failed to cap a culture of staphylococci, which were later found to be killed by a mold.
After intensive research, Sir Fleming discovered that this mold belonged to a family of molds called penicillin. People soon saw its potential use, which is later known as “penicillin”.
Today, researchers have developed antiviral drugs, most notably the antiviral drug azidothymidine for AIDS – which can also treat many other viral diseases.
5. Contraceptive drugs
Although the spread of contraceptive use has not been smooth, few inventions have probably had such a profound impact on society as it has.
The U.S. Federal Drug Administration confirmed the safety of the pill as early as the early 1960s, but its use was not legal until 1965 for married couples and by 1972 for unmarried men and women.
Thanks to the pill, untold numbers of women have taken control of their fertility – an invention that has sparked a social revolution.
6. Advances in heart surgery and heart care
Heart disease continues to be a killer that threatens human health. Nonetheless, many important advances in the treatment of heart disease have yielded dramatic results, extending the lives of patients and improving their quality of life. One of the most important of these advances is the ability of surgeons to perform heart surgery and repair the heart without significant risk to the patient.
The breakthrough advance was the advent of cardiopulmonary bypass, which allowed heart surgery to be performed in just minutes at a time. This was followed by coronary artery bypass grafting.
7. Randomized controlled trials
There is one more advancement that the public has largely ignored, and that is the randomized controlled trial. Called by many the “gold standard” of medical research, it provides medical researchers with important indicators to determine which treatments work and which do not.
Randomized trials have brought us into an era of evidence-based medicine and continue to guide daily clinical practice.
8. Radiography
Before the invention of radiological imaging (first X-rays) technology, doctors could usually only see the external symptoms of a wound or trauma.
Now, this technology can penetrate inside the body to determine the cause, extent or symptoms of a disease, revolutionizing every aspect of medicine and saving countless lives.
CT scans did not appear until the 1970s.
9. Improvements in childbirth techniques
Until the mid-20th century, Americans considered childbirth to be the most terrifying part of a woman’s life.
With the advent of anesthesia, cesarean sections, forceps, and other techniques, the chances of a successful birth improved, at least in the developed world.
10. Organ Transplants
Today, there are few procedures as complex and ethical as organ transplantation.
The complexity of this procedure is truly amazing, combining surgery and immunology into one.
The first successful organ transplant occurred in 1954, when a kidney was removed from one of twins and transplanted into the other. Other organ transplants followed, including the first liver transplant in 1963, and the first heart transplant in 1967.
