How did Ignaz Semmelweis make his discovery?
Ignaz Semmelweis introduced handwashing standards after discovering that the occurrence of puerperal fever could be prevented by practicing hand disinfection in obstetrical clinics. Thus, Semmelweis suggested the use of chlorinated lime solution for handwashing to prevent the infectious disease from spreading.
Who was Ignaz Semmelweis what theory did he have?
cadaverous poisoning
Theory of cadaverous poisoning Semmelweis immediately proposed a connection between cadaveric contamination and puerperal fever. He proposed that he and the medical students carried “cadaverous particles” on their hands from the autopsy room to the patients they examined in the First Obstetrical Clinic.
What did Ignaz Semmelweis do microbiology?
Ignaz Philipp Semmelweis demonstrated that the use of disinfectants could reduce the occurrence of puerperal fever in patients in nineteenth century Austria. Puerperal fever is a bacterial infection that can occur in the uterine tract of women after giving birth or undergoing an abortion.

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.
Why was the work of Ignaz Semmelweis so important?
Ignaz Semmelweis was the first doctor to discover the importance for medical professionals of hand washing. After Semmelweis initiated a mandatory hand-washing policy, the mortality rate for women delivered by doctors fell from 18 per cent to 2 per cent – the same as it was for midwives.
What was Semmelweis experiment?
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 did Ignaz Semmelweis invent hand-washing?
Students and physicians regularly went between autopsies and deliveries, rarely washing their hands in between. Gloves were not commonly used in hospitals or surgeries until late in the 19th century. Realizing that chloride solution rid objects of their odors, Semmelweis mandated hand-washing across his department.
