Historical mortality rates of puerperal fever


Historically, puerperal fever was a devastating disease. It affected women within the first three days after childbirth and progressed rapidly, causing acute symptoms of severe abdominal pain, fever and debility.

The most common infection causing puerperal fever is genital tract sepsis caused by contaminated medical equipment or unhygienic medical staff who contaminate the mother's genital tract during the delivery. Other types of infection that can lead to sepsis after childbirth include urinary tract infection, breast infection (mastitis) and respiratory tract infection (more common after anaesthesia due to lesions in the trachea). Puerperal fever is now rare in the West due to improved hygiene during delivery, and the few infections that do occur are usually treatable with antibiotics.

Dr. Ignaz Semmelweis worked at the Vienna General Hospital's maternity clinic on a 3-year contract from 1846–1849. There, as elsewhere in European and North American hospitals, puerperal fever, or childbed fever, was rampant, sometimes climbing to 40 percent of admitted patients. He was disturbed by these mortality rates, and eventually developed a theory of infection, in which he theorized that decaying matter on the hands of doctors, who had recently conducted autopsies, was brought into contact with the genitals of birthgiving women during the medical examinations at the maternity clinic. He proposed a radical hand washing theory using chlorinated lime, now a known disinfectant.

At the time however, the germ theory of infection had not been developed and Semmelweis' ideas ran contrary to key medical beliefs and practices. His ideas were rejected and ridiculed. Quite unusually, his contract was not renewed, effectively expelling him from the medical community in Vienna. He died as an outcast in a mental institution.

An 1841 account of epidemic childbed fever states that insofar as existing historical documents permit one to judge, childbed fever is a modern disease. The cases reported by Hippocrates that are generally identified as such are not puerperal fever. There are only examples of bilious fever, then common, which among maternity patients was no different from its appearance among non-maternity patients or men; Hippocrates himself never identified it as a separate and distinguishable disease.
