Until the 19th century, surgery remained a brutal craft often left to
barbers simply because they had the cutting tools. The lack of
anything to kill the pain of surgery, along with continuing
reservations against dissection, created a vicious cycle where there
were few people willing to undergo surgery, which led to limited
research and knowledge, further discouraging people from undergoing
surgery and so on. Thus surgery progressed very little through the
centuries. All that changed in the 19th century.
It started with the discovery of the anesthetic properties of ether and
chloroform in the 1840s, thus making surgeries painless, although there
was plenty of pain after the anesthetics wore off. Still, the number
of people willing to undergo surgery rapidly multiplied. However this
led to another problem: infections from surgery killing patients after
presumably successful surgeries. Previously, with so few people
willing to undergo surgery, and so many of them dying on the operating
table, infections from surgery itself were relatively rare, and their
causes (i.e., unclean surgical instruments and operating conditions)
remained a mystery. Then came the answer: germs.
When people such as Louis Pasteur and Joseph Lister first linked
microbes to disease and infection, they were met by widespread
skepticism from people who refused to believe disease and infection
could come from things so small we can’t see them without a
microscope. However, when Pasteur came up with a vaccine against
rabies based on his theory, people took notice. Lister applied this
theory to surgery by spraying a fine mist of carbolic acid on patients
during surgery to kill any germs. As a result, deaths from infections
after surgery dropped dramatically.
Unfortunately, some patients and medical staff reacted badly to the
carbolic acid. This had two results. First, experiments showed that
patients’ infections had the same germs as those on surgeons’ hands.
Secondly, to protect his trusted head nurse’s sensitive hands, Lister
had the Goodyear Rubber Company make some rubber gloves. Out of these
two things came aseptic procedure, where everything in the operating
room was sterilized, thus eliminating the need for the annoying
carbolic acid. Ironically, the rubber gloves first developed to
protect the hands of Lister’s head nurse (whom he later married) were
now used to protect the patient from germs on the medical staff’s hands.
Aseptic procedure drastically reduced the number of infections from
surgery and dramatically increased the number of surgeries being
performed. This brought up another problem: blood loss. At first,
doctors tried random blood transfusions from other people, saving some
patients but killing others. This led to new research and the
discovery of blood types. Now blood donors’ blood could be accurately
matched with that of patients.
Then came World War I and the need for blood donors drastically
increased. However, donors’ blood clotted soon after being taken,
preventing its storage or transport long distances to field hospitals
where it was needed. Then someone discovered that sodium citrate kept
blood from clotting, thereby saving thousands of lives.
In spite of all these advances, invasive procedures like surgery were
still a shock to the system and quite painful during recuperation.
Fortunately, one more discovery during World War II helped reduce the
need for surgeries: penicillin and other antibiotics that could cure
infections without the patient having to go under the knife.
Since World War II a staggering number of advances in surgery have
taken place. At the same time germs have mutated quickly, so our
arsenal of antibiotics is becoming less and less effective. The battle
goes on.
