He eliminated climate as a cause because the climate was the same. Semmelweis immediately proposed a connection between cadaveric contamination and puerperal fever.

This explained why the student midwives in the Second Clinic, who were not engaged in autopsies and had no contact with corpses, saw a much lower mortality rate. The germ theory of disease had not yet been accepted in Vienna. Thus, Semmelweis concluded some unknown "cadaverous material" caused childbed fever.

He instituted a policy of using a solution of chlorinated lime calcium hypochlorite for washing hands between autopsy work and the examination of patients.

He did this because he found that this chlorinated solution worked best to remove the putrid smell of infected autopsy tissue, and thus perhaps destroyed the causal "poisonous" or contaminating "cadaveric" agent hypothetically being transmitted by this material. The mortality rate in April was After hand washing was instituted in mid-May, the rates in June were 2. He was dismissed from the hospital for political reasons and harassed by the medical community in Vienna, being eventually forced to move to Budapest.

Semmelweis was outraged by the indifference of the medical profession and began writing open and increasingly angry letters to prominent European obstetricians, at times denouncing them as irresponsible murderers. He died there of septic shock only 14 days later, possibly as the result of being severely beaten by guards. He is considered a pioneer of antiseptic procedures. Conflict with established medical opinion[ edit ] Main article: Contemporary reaction to Ignaz Semmelweis Puerperal fever monthly mortality rates for the First Clinic at Vienna Maternity Institution — Rates drop markedly when Semmelweis implemented chlorine hand washing mid-May see rates.

The theory of diseases was highly influenced by ideas of an imbalance of the basic " four humours " in the body, a theory known as dyscrasia , for which the main treatment was bloodlettings. The findings from autopsies of deceased women also showed a confusing multitude of physical signs, which emphasized the belief that puerperal fever was not one, but many different, yet unidentified, diseases.

Also, some historians of science [16] argue that resistance to path-breaking contributions of obscure scientists is common and "constitutes the single most formidable block to scientific advances. Other, more subtle, factors may also have played a role. Some doctors, for instance, were offended at the suggestion that they should wash their hands, feeling that their social status as gentlemen was inconsistent with the idea that their hands could be unclean.

That became possible only some decades later, when Louis Pasteur , Joseph Lister , and others further developed the germ theory of disease. During , Semmelweis widened the scope of his washing protocol, to include all instruments coming in contact with patients in labour, and used mortality rates time series to document his success in virtually eliminating puerperal fever from the hospital ward. Hesitant publication of results and first signs of trouble[ edit ] Streptococcus pyogenes red-stained spheres is responsible for most cases of severe puerperal fever.

It is commonly found in the throat and nasopharynx of otherwise healthy carriers. Toward the end of , accounts of the work of Semmelweis as well as the similar conclusions of Holmes, working in America [14] began to spread around Europe. Semmelweis and his students wrote letters to the directors of several prominent maternity clinics describing their recent observations. The lecture was presented before the Royal Medical and Surgical Society in London and a review published in The Lancet , a prominent medical journal.

Early responses to his work also gave clear signs of coming trouble, however. Some physicians had clearly misinterpreted his claims. At this crucial stage, Semmelweis himself had published nothing. These and similar misinterpretations continued to cloud discussions of his work throughout the century.

Political turmoil and dismissal from the Vienna hospital[ edit ] In , a series of tumultuous revolutions swept across Europe. In Vienna on 13 March students demonstrated in favor of increased civil rights , including trial by jury and freedom of expression. The demonstrations were led by medical students and young faculty members and were joined by workers from the suburbs.

Two days later in Hungary, demonstrations and uprisings led to the Hungarian Revolution of and a full-scale war against the ruling Habsburgs of the Austrian Empire.

In Vienna, the March demonstration was followed by months of general unrest. Some of his brothers were punished for active participation in the Hungarian independence movement, and the Hungarian-born Semmelweis likely was sympathetic to the cause. Klein probably mistrusted Semmelweis. Semmelweis and Braun were the only two applicants for the post.

Semmelweis was obliged to leave the obstetrical clinic when his term expired on March 20, A docent was a private lecturer who taught students and who had access to some university facilities. A few days after being notified of his appointment, Semmelweis left Vienna abruptly and returned to Pest. He apparently left without so much as saying good-bye to his former friends and colleagues, a move that might have offended them. Semmelweis, upon arriving from the Habsburg Vienna in , likely was not warmly welcomed in Pest.

He held that position for six years, until June After taking over in , Semmelweis virtually eliminated the disease.

During —, only eight patients died from childbed fever out of births 0. He continued to believe that puerperal fever was due to uncleanliness of the bowel. After Birly died in , Semmelweis applied for the position. Semmelweis was eventually appointed in , but only because the Viennese authorities overruled the wishes of the Hungarians, as Braun did not speak Hungarian. As professor of obstetrics, Semmelweis instituted chlorine washings at the University of Pest maternity clinic.

Once again, the results were impressive. They had five children. The second vertical line marks introduction of chlorine hand washing in Rates for the Dublin Rotunda maternity hospital , which had no pathological anatomy, are shown for comparison view rates. The British consistently regarded Semmelweis as having supported their theory of contagion.

A typical example was W. Tyler Smith, who claimed that Semmelweis "made out very conclusively" that " miasms derived from the dissecting room will excite puerperal disease. Simpson surmised that the British obstetrical literature must be totally unknown in Vienna, or Semmelweis would have known that the British had long regarded childbed fever as contagious and would have employed chlorine washing to protect against it.

In his book, Semmelweis lamented the slow adoption of his ideas: "Most medical lecture halls continue to resound with lectures on epidemic childbed fever and with discourses against my theories.

Other causes included conception and pregnancy, uremia, pressure exerted on adjacent organs by the shrinking uterus, emotional traumata, mistakes in diet, chilling, and atmospheric epidemic influences. These results suggest that Braun continued, assiduously, to require the chlorine washings. At a conference of German physicians and natural scientists , most of the speakers rejected his doctrine, including the celebrated Rudolf Virchow , who was a scientist of the highest authority of his time.

Breisky objected that Semmelweis had not proved that puerperal fever and pyemia are identical, and he insisted that other factors beyond decaying organic matter certainly had to be included in the etiology of the disease.

He suffered from severe depression and became absentminded. Paintings from to show a progression of aging. After a number of unfavorable foreign reviews of his book, Semmelweis lashed out against his critics in a series of Open Letters. They were full of bitterness, desperation, and fury and were "highly polemical and superlatively offensive", [53] at times denouncing his critics as irresponsible murderers [54] or ignoramuses.

He also began to drink immoderately; he spent progressively more time away from his family, sometimes in the company of a prostitute; and his wife noticed changes in his sexual behavior. He was severely beaten by several guards, secured in a straitjacket , and confined to a darkened cell. Apart from the straitjacket, treatments at the mental institution included dousing with cold water and administering castor oil , a laxative. He died after two weeks, on August 13, , aged 47, from a gangrenous wound, due to an infection on his right hand which might have been caused by the struggle.

The autopsy gave the cause of death as pyemia — blood poisoning. Only a few people attended the service. Although the rules of the Hungarian Association of Physicians and Natural Scientists specified that a commemorative address be delivered in honor of a member who had died in the preceding year, there was no address for Semmelweis; his death was never even mentioned. On 11 October , they were transferred once more to the house in which he was born. The house [4] is now a historical museum and library, honoring Ignaz Semmelweis.
