Chloroform Committee
The Chloroform Committee was commissioned by the Royal Medical and Chirurgical Society (now known as the Royal Society of Medicine) in 1864 to investigate the use of chloroform. The committee recommended the use of chloroform in the same year (although ether In organic chemistry, ethers are a class of compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. They have the general formula , where R and R′ represent the alkyl or aryl groups. Ethers can again be c ... was safer for patients). It was the first of such committees (see the box at the bottom of this page) and concluded that chloroform depresses the action of the heart and frequently kills. One of the members, Joseph Clover, during his time on the committee developed apparatus for using chloroform called the Clover bag.

Royal Medical And Chirurgical Society
The Medical and Chirurgical Society of London was a learned society of physicians and surgeons which was founded in 1805 by 26 personalities in these fields who had left the Medical Society of London (founded 1773) because of disagreement with the autocratic style of its president, James Sims. Among its founders there were William Saunders (1743–1817), its first president; John Yelloly (1774–1842), Sir Astley Cooper (1768–1841), the first treasurer; Alexander Marcet (1770–1822) and Peter Mark Roget (1779–1869). According to its charter, the Medical and Chirurgical Society of London was founded "for the purpose of conversation on professional subjects, for the reception of communications and for the formation of a library" and served "several branches of the medical profession". In 1834 the Society received a Royal charter, thus becoming the Royal Medical and Chirurgical Society of London. This society merged with several other specialist societies, from 1907 to 1909, ...

Royal Society Of Medicine
The Royal Society of Medicine (RSM) is a medical society in the United Kingdom, headquartered in London. History The Society was established in 1805 as Medical and Chirurgical Society of London, meeting in two rooms in barristers’ chambers at Gray's Inn and then moving to Lincoln's Inn Fields where it stayed for 25 years. In 1834 the Society moved to Berners Street and was granted a Royal Charter by King William IV. In 1889 under the leadership of Sir John MacAlister, a Building Committee chaired by Timothy Holmes supervised the move of the quarters of the Society from Berners Street to 20 Hanover Square. In 1905 an eleven-member committee headed by Sir Richard Douglas Powell organised the celebration of the Society's centenary. Two years later the Royal Medical and Chirurgical Society of London came together with seventeen specialist medical societies and, with a supplementary Royal Charter granted by Edward VII, became the Royal Society of Medicine. In 1910 the Society ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloroform
Chloroform, or trichloromethane, is an organic compound with chemical formula, formula Carbon, CHydrogen, HChlorine, Cl3 and a common organic solvent. It is a colorless, strong-smelling, dense liquid produced on a large scale as a precursor to PTFE. It is also a precursor to various refrigerants. It is trihalomethane. It is a powerful anesthetic, euphoriant, anxiolytic, and sedative when inhaled or ingested. Structure The molecule adopts a tetrahedral molecular geometry with C3v symmetry group, symmetry. Natural occurrence The total global flux of chloroform through the environment is approximately tonnes per year, and about 90% of emissions are natural in origin. Many kinds of seaweed produce chloroform, and fungi are believed to produce chloroform in soil. Abiotic processes are also believed to contribute to natural chloroform productions in soils although the mechanism is still unclear. Chloroform volatilizes readily from soil and surface water and undergoes degradation in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diethyl Ether
Diethyl ether, or simply ether, is an organic compound in the ether class with the formula , sometimes abbreviated as (see Pseudoelement symbols). It is a colourless, highly volatile, sweet-smelling ("ethereal odour"), extremely flammable liquid. It is commonly used as a solvent in laboratories and as a starting fluid for some engines. It was formerly used as a general anesthetic, until non-flammable drugs were developed, such as halothane. It has been used as a recreational drug to cause intoxication. Production Most diethyl ether is produced as a byproduct of the vapor-phase hydration of ethylene to make ethanol. This process uses solid-supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises. Vapor-phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95%. Diethyl ether can be prepared both in laboratories and on an industrial scale by the acid ether synthesis. Ethanol is mixed with a stro ...

Clover Bag
Joseph Thomas Clover (28 February 1825; baptised 7 May 1825 – 27 September 1882) was an English doctor and pioneer of anaesthesia. He invented a variety of pieces of apparatus to deliver anaesthetics including ether and chloroform safely and controllably. By 1871 he had administered anaesthetics 13,000 times without a fatality. Clover assisted at surgery of public figures including Napoleon III, Princess Alexandra of Denmark and her husband King Edward VII (then Prince of Wales), Sir Robert Peel, and Florence Nightingale. His inventions included the bulky 'Clover's chloroform apparatus' (1862), with which he was often photographed; and the compact 'Clover's portable regulating ether inhaler' (1877), which remained in use well into the 20th century. With fellow pioneer John Snow, Clover is one of the supporters on the crest of the Royal College of Anaesthetists. Early life Clover was born in the town of Aylsham, Norfolk Rushman, page 27. to John Wright Clover, a draper and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Anesthesia
Anesthesia is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness. An individual under the effects of anesthetic drugs is referred to as being anesthetized. Anesthesia enables the painless performance of procedures that would otherwise cause severe or intolerable pain in a non-anesthetized individual, or would otherwise be technically unfeasible. Three broad categories of anesthesia exist: * General anesthesia suppresses central nervous system activity and results in unconsciousness and total lack of sensation, using either injected or inhaled drugs. * Sedation suppresses the central nervous system to a lesser degree, inhibiting both anxiety and creation of long-term memories without resulting in unconsciousness. * Regional and local anesthesia, which blocks ...

Committees
A committee or commission is a body of one or more persons subordinate to a deliberative assembly. A committee is not itself considered to be a form of assembly. Usually, the assembly sends matters into a committee as a way to explore them more fully than would be possible if the assembly itself were considering them. Committees may have different functions and their types of work differ depending on the type of the organization and its needs. A member of a legislature may be delegated a committee assignment, which gives them the right to serve on a certain committee. Purpose A deliberative assembly may form a committee (or "commission") consisting of one or more persons to assist with the work of the assembly. For larger organizations, much work is done in committees. Committees can be a way to formally draw together people of relevant expertise from different parts of an organization who otherwise would not have a good way to share information and coordinate actions. They may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
