The Introduction of Antiseptics

 

The practice of surgery has been around as early as 10,000 B.C.  But it wasn’t until the late 1800s, with the systematic thinking of Joseph Lister, were antiseptics finally introduced and widely used for sterilization of surgical instruments and dressings.

 

Joseph Lister was a British surgeon who was among those selected to be a surgeon at the new surgical building in the Glasgow Royal Infirmary in 1861.  Here he was able to study the devastating effects of sepsis on patients following surgical treatment.  In the mid-nineteenth century, the mortality rate for post-operative cases, such as amputee patients, was as high as 46% prior to the use of antiseptics.  It was in his Male Accident Ward, in which Lister noted the death rate from post-operative infection to be between 45-50% during the years 1861 and 1865, where he began to investigate the causes of sepsis more carefully.

 

The predominant cause of sepsis within the medical community was thought at the time to be “bad air”.  Thus, the ward Lister worked in was constructed with the hope that performing surgeries in this new unit would prevent sepsis from occurring.  This hope was diminished when patients continued to acquire gangrene and other infections.  Through his observations, Lister knew there had to be more to the story.  He speculated that sepsis, was not merely caused by bad air, but was actually decaying of the flesh brought about by “pollen-like dust”.  He recalled the 1865 work of Louis Pasteur who had determined that fermentation of microorganisms upon entering the flesh causes putrefaction or flesh decomposition, and saw the relationship between Pasteur’s finding and the sepsis seen in his patients.  Lister decided that in order to rid the operation rooms of these harmful living organisms, he would spray the air with carbolic acid, used at the time as a sewage treatment to control typhoid disease.  He later treated surgical instruments and wounds and dressings with carbolic acid for sterilization.  With his new antiseptic techniques, the mortality rate after surgery was reduced to 15%.

 

Joseph Lister’s new methods were simple, but were not without some initial opposition from the medical community.  But it was more his theory of the causes of sepsis that stirred up debate rather than his antiseptic system.  He was able to show that using carbolic acid as a sterilizer in the surgical wards successfully prevented sepsis in 1877 and by the 1880s, Lister’s antiseptic practices became more accepted.  Although Lister’s original carbolic acid spray is no longer used today, other antiseptics and aseptic techniques have been developed for surgical use.

 

Questions for Discussion

 

  1. Why do you think the majority of medical professionals believed that sepsis was caused by “bad air”?
  2. Is this kind of thinking an example of “poor” science?  Why or why not?
  3. Why do you think Joseph Lister’s germ theory was met with resistance from the medical community? 
  4. Do you think Lister could have made his discovery of the importance of antiseptics without Louis Pasteur’s findings?
  5. In your opinion, is collaboration or working together in the scientific field important?  Why or why not?
