The study of general anesthesia is, then, a study in toxicology; and the production of ether or chloroform anesthesia is the production of acute ether or chloroform poisoning, the patient being drugged into a state of narcosis bordering on collapse. Morton publicly demonstrates the use of ether as an effective surgical anesthetic. The cessation of respiration under chloroform, and its restoration by a new method, 1885. Chloroform anesthesia may be admissible for the few minutes at the end of the delivery, but when operative measures are necessary, before or after delivery, it is a dangerous anesthetic and surely capable of producing injury to the liver in the manner recognized in the case of normal persons. . John Snow's accomplishments in medicine, anesthesia, and epidemiology constituted an achievement that changed the face of medical practice. Today chloroform is no longer used as an anesthetic, but since it is a byproduct of water chlorination, we are exposed to small doses in our drinking water.

Chloroform anesthesia causes no injury to the liver of the fetus nor to any other fetal organ, in spite of the fact that it can be demonstrated to be present in these tissues. It is a trichloromethane derivative with an ether-like odor. Chloroform, which had been discovered in 1832, was soon in common use as well. Inhaling chloroform vapors depressed the central nervous system of a patient, causing dizziness, fatigue and unconsciousness, allowing a doctor to perform simple surgery or other painful operations. Anesthesia was used in 95% of Civil War surgeries. Chloroform is a colorless, fragrant liquid, that is highly volatile, and feels cool to the touch. Soon thereafter, the chemical reactivity of aerobically heated chloroform permitted John Snow and Claude Bernard to do seminal experiments in the assay of drug levels and drug metabolism. By the time the American Civil War broke out in 1861, both ether and chloroform had been in use for several years as methods of surgical anesthesia. 1846 - Boston dentist William T.G.
