Anesthetic ether is the actually diethyl ether CH3CH2OCH2CH3. It has been used as an anesthetic in medical surgery for over 150 years, though the hypnotic effects of ether was already discovered 500 years ago. The historical development of ether anesthesia is very dramatic and interesting. Ether anesthesia: The historical development Ether was discovered in 1275 by Spanish chemist Raymundus Lullius, and was named ? §sweet vitriol. ” In 1540, a German scientist Valerius Cordus described the synthesis of ether . At about the same time, Swiss physician and alchemist Paracelsus discovered the hypnotic effects of ether.
In 1730, a German scientist W. G. Frobenius renamed the chemical sweet vitriol into ether. Scientists and physicians used ether for many different things, but not yet as an anesthetic agent. In 1794, English physicians Richard Pearson and Thomas Beddoes used ether in the treatment of phthisis, catarrhal fever, bladder calculus, and scurvy. These treatments were performed at the Beddoes’ Pneumatic Institute. A little later in 1805, American physicians used ether to treat pulmonary inflammation. Dr. Crawford Williamson Long is the person who first introduced surgical anesthetic use of ether.
On March 30, 1842, he removed a tumor from the neck of Mr. James Venable under ether anesthesia. Apparently, he had been using ether for minor surgery as early as in the year of 1841, and had originally learned about ether while in medical school at the University of Pennsylvania. However Dr. Long, he did not publish the results until 1848, appearing in The Southern Medical and Surgical Journal. The late publishing of his surgical report made him missed the credit of the discovery of ether anesthesia, which was given to Morton, which will be mentioned below.
Before ether, the most common anesthetics used in surgical and medical treatments were chloroform and nitrous oxide. In 1844, Connecticut dentist Dr. Horace Wells, age 29, focused his career on the promotion of nitrous oxide anesthesia. Dr. Wells tried to promote his nitrous anesthesia technique in the Boston medical community without much success. He even used the influence of former dental partner Dr. William T. G. Morton, whom had good standing in the local community. They had a shared dental practice back in 1843, and earlier, Morton had actually been tutored in dentistry by Wells.
Finally, Dr. Wells was allowed a public demonstration in January 1845 at the Massachusetts General Hospital. The demonstration failed, perhaps due to the dose of nitrous oxide was insufficient. After that Wells left Boston and returned to Hartford and continued his futile promotion of nitrous oxide. Although Dr. Wells failed to demonstrate nitrous oxide anesthesia, chemist and physician Dr. Charles T. Jackson showed interest in his work, and consulted with Wells on the properties of both ether and nitrous oxide.
Dr.Jackson was a professor at the Medical College of Massachusetts. Dr. Morton, a dentist, was also a pre-medical student. In coincidence, Dr. Jackson had tutored Dr. Morton in 1844, preparing him for medical school. Dr. Morton began to receive information about the use of ether from his friend and colleague Dr. Jackson. In 1846, after learning more about ether? ¦s properties, Morton started secret experiments with ether. He experimented on himself as well as small animals at his home in West Needham, Massachusetts.
On September 30, 1846 at 9 p. m.in his Boston office, he painlessly removed a tooth from a city merchant Eben H. Frost. The use of ether was successful in Morton’s dental practice, and local newspaper began to publicize Morton’s technique. Junior surgeon Dr. Henry Jacob Bigelow noticed these paper articles, and arranged for a demonstration with his colleague, Dr. John Collins Warren, age 68, Senior Surgeon at the Massachusetts General Hospital. To administer the ether, a glass reservoir incorporating pass-over vaporization was developed by Joseph M. Wightman and Nathan B. Chamberlain.
At last, the first successful demonstration of ether anesthesia occurred at the Massachusetts General Hospital on October 16, 1846 at approximately 10:15 a. m. After administering the ether, Morton said to Dr. Warren, “Your patient is ready, sir. ” Under general anesthesia, Dr. Warren removed a congenital vascular malformation from 20 year-old Edward Gilbert Abbott’s neck, a printer and editor. After the surgery, the patient replied “I did not experience pain at any time, though I knew that the operation was proceeding. ” Dr. Warren remarked, “Gentlemen, this is no humbug.
” This demonstration was a landmark in the history of anesthesia. In the years following the initial demonstration by Morton, a feud developed between Morton, Jackson, Wells, and Long. All of them thought they should be credited and profit from the discovery of ether anesthesia. After Morton had completed a few ether demonstrations, he immediately started to promote his discovery. Bostonian R. H. Eddy, who was the son of a patent commissioner and a friend of Jackson, convinced Morton and Jackson to patent the discovery. Morton later obtained an application on October 27, and it was subsequently granted on November 12.
He called the substance “Letheon. ” He spent all his time and money promoting the use of Letheon instead of practicing denistry. Initially, he refused to reveal the nature of the solution. This drew a strong negative response from the medical community, including the surgeons at the Massachusetts General Hospital. However, the distinct smell was soon recognized. In 1847, Morton published the first article on the use of ether, titled “Remarks on the Proper Mode of Administering Sulfuric Ether by Inhalation. ” In addition, for years he petitioned the U. S.
Congress to recognize him as the principle discoverer of ether, and to compensate him for the use of his patent (U. S. Patent No. 4848, November 12, 1846). An appropriation bill for $100,000 was approved in 1852 and 1854, but the Senate failed it. He never received his money and eventually lead him to bankruptcy. He died at age 49 from a stroke and left without any money to his wife. Jackson also claimed to have been responsible for the discovery. In 1846, the Monthyon Prize of 5,000 francs was awarded by the French Academy of Medicine to Jackson and Morton.
However, Morton refused share the prize with Jackson, claiming that the discovery was his alone. He suffered a stroke with paralysis and speech impairment, and he had gone mad probably due to the disability. Wells gave up his dental practice after a fatality. In the winter of 1847-1848, Wells visited New York. He began experiments with chloroform but soon became addicted. On January 21, 1848, while under the influence of chloroform Wells threw acid on the clothing of a prostitute and he was jailed. Two days later, he committed suicide by slashing his thigh with a razor in the jail and died at the age of 33.
Some people believed the development of ether anesthesia had been cursing the people involved, but the discovery of ether as a surgical anesthetic is certainly a great milestone to the development of modern medical surgery. Ether anesthesia after Morton Primary Ether Anesthesia The systematic use of ether? ¦s early analgesic stage became popular in Germany after P. Sudeck in 1901 introduced a procedure that he called ? §Aetherrausch.?? Sudeck is generally considered to be the inventor of ether analgesia. However, in 1872, 29 yr before Sudeck, John H. Packard of Philadelphia had reported an almost identical technique.
Packard called his method ? §first insensibility to ether?? or ? §primary anesthesia.?? In 1872, Packard6 reported having noticed that ether initially induced a short stage of analgesia or anesthesia that he called ? §first insensibility from ether.?? Packard used his ? §primary anesthesia?? for brief, painful procedures such as reductions of fractures and dislocations. Before the surgical operation, he used a cone formed of a newspaper or cardboard with an inner lining made of a thin towel or handkerchief as an inhaler. He occasionally used a simple sponge or a folded towel.
He ?§dashed?? 14. 8 ml ether on the whole surface of the material to speed up its evaporation. The patient, sitting or reclining, held the sponge, the towel, or the base of the cone against his face with one hand while keeping the other hand raised. The surgeon, ready to operate, observed the patient and urged him to breathe vigorously and to keep the hand up. Anywhere from one to several minutes later, the patient invariably dropped the hand. This sudden ? §loss of voluntary muscle power,?? according to Packard, was a reliable and consistent sign of the onset of a brief period of ?
§absolute insensibility.?? The surgeon should proceed as soon as this occurred. The patient woke up within one minute, ? §without nausea, headache, tedious period of recovery, or other unpleasant sequels of prolonged ether anesthesia?? and could be discharged home shortly thereafter. In 1901, Sudeck presented to the Hamburg Medical Association a method very similar to that of Packard that he named ? §Aetherrausch??. With Sudeck? ¦s reputation, his enthusiasm for his technique, and the fatalities caused by chloroform in minor surgery helped spread the use of the ? §Aetherrausch??
in Germany where, it remained popular until the early 1940s. Some drawbacks of ether Ether can induce visual illusions and hallucinations. Besides euphoria, ether also intoxicate human with dizziness, slight ataxia, drowsiness and blurred vision. Also, great cerebral derangement will be produced by too freely inhaling ether. In early stage of ether anesthesia development medical surgeons often encountered over dosages of ether to patients. Reference Jay V. This month in medicine: ether day.
