Is puerperal fever contagious?
“The disease, known as Puerperal Fever, is so far contagious as to be frequently carried from patient to patient by physicians and nurses.”
What was Ignaz Semmelweis contribution to microbiology?
Ignaz Philipp Semmelweis was a Hungarian gynecologist who is known as a pioneer of antiseptic procedures. Semmelweis discovered that the incidence of puerperal fever could be drastically cut by the use of hand disinfection in obstetrical clinics.
What did Semmelweis tell his staff?
He believed that microbes causing infection were readily transferred from patients to patients, medical staff to patients and vice versa. Thus, Semmelweis suggested the use of chlorinated lime solution for handwashing to prevent the infectious disease from spreading.
How did Louis Pasteur prove germs caused infectious diseases?
The more formal experiments on the relationship between germ and disease were conducted by Louis Pasteur between the years 1860 and 1864. He discovered the pathology of the puerperal fever and the pyogenic vibrio in the blood, and suggested using boric acid to kill these microorganisms before and after confinement.
Why was Ignaz Semmelweis not taken seriously?
Most of the objections from Semmelweis’s critics stemmed from his claim that every case of childbed fever was caused by resorption of cadaveric particles. Some of Semmelweis’s first critics even responded that he had said nothing new – it had long been known that cadaveric contamination could cause childbed fever.
What happened when Dr Semmelweis insisted that his students wash their hands before treating mothers having babies in the maternity ward?
So Semmelweis hypothesized that there were cadaverous particles, little pieces of corpse, that students were getting on their hands from the cadavers they dissected. And when they delivered the babies, these particles would get inside the women who would develop the disease and die.
Why were doctors so resistant to Semmelweis’s ideas?
Semmelweis correctly concluded that infection of childbed fever was carried by doctors themselves from morgue (where doctors examined cadavers of patients who died earlier after child birth) to maternity unit. Doctors somehow could not accept the fact that they themselves were responsible for death of their patients.
