Fidel Pagés, a Spanish surgeon, tragically died in 1923 at the age of 37, just 2 years after his publication "Anestesia Metamérica," the first description of human thoracolumbar epidural anesthesia. In the intervening 100 years, epidural anesthesia has faced countless obstacles, starting with the dissemination of his initial report, which was not widely read nor appreciated at the time. However, the merits of the technique have fueled innovations to meet these challenges over the years. Even today, while epidural anesthesia is widely embraced, particularly in obstetric and chronic pain medicine, the pressures of the operating room for efficiency and a low tolerance for failure, pose modern-day challenges. Here, we revisit Pagés' original report and highlight the key innovations that have allowed for the evolution of this essential anesthesia technique., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 International Anesthesia Research Society.)

The British Journal of Anaesthesia (BJA) celebrates its centenary in 2023, and with it 100 yr of continuous anaesthesia research publication. As an editorially and financially independent journal, the BJA faced a rapidly changing anaesthesia profession, health system, and publishing world without the security of institutional support. In its early days, the Journal was vocal about the challenging conditions faced by anaesthetists before the National Health System was established, and was essential in advocating for the specialty. Although the years after World War II brought improving fortunes for the specialty, the BJA found itself struggling to publish. As the Journal's fortunes began to improve, a new research and healthcare context emerged, radically changing the face of anaesthesia research and practice, to which the Journal needed to adapt. In spite of a range of challenges throughout the years, the BJA has developed into an international, future-focused, well-respected publication. This could not have been achieved without continual transformation, and the willingness to take risks and meet the changing times head on., (Copyright © 2023 The Author(s).

Richard Gordon (1921-2017) was a prolific writer of both humorous fiction and historical reviews. He trained in medicine at St Bartholomew's Hospital (Barts) in London and specialised in anaesthesia working at Hill End Hospital, St Albans (where a large proportion of Barts work took place to avoid the impact of the Blitz during the Second World War) and at the Radcliffe Infirmary, Oxford with Robert Macintosh. He published multiple papers and a book on trichlorethylene anaesthesia and edited a textbook of anaesthesia for medical students which ran for 10 editions. His gift for writing and his prominent public persona placed him in a unique position to highlight the importance of the newly emerging speciality of anaesthesia. He did the exact opposite of this and instead created a representation of an uninterested spectator to surgical activity, a representation which still persists in some quarters today.

Thomas Drysdale Buchanan, MD (1876-1940), founding president of the American Board of Anesthesiology, was the first person in the United States to hold the title "Professor of Anesthesiology" in a medical school faculty position dedicated exclusively to the specialty. An 1897 graduate of New York Medical College, Dr Buchanan joined the faculty of his alma mater in 1902 in response to demands by medical students and recent graduates for a dedicated instructor in anesthesia. Within a decade, the instructorship had become a professorship, and Dr Buchanan was on his way to distinction as one of the founders of academic anesthesiology. This chapter in Dr Buchanan's early career illustrates how anesthesiology took shape as a distinct body of knowledge during the formative decades of modern medical education at the turn of the century, laying the groundwork for its recognition 30 years later as a specialty in its own right., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 International Anesthesia Research Society.)

This special article briefly discusses the role of women as the new journal Current Researches in Anesthesia and Analgesia (now Anesthesia & Analgesia [A&A]) began in 1922. It was a time of a few women physicians, and they were usually isolated from the world of mainstream medicine and its predominantly male practitioners The journal's founders, Frank McMechan and his wife Laurette of Cincinnati, were committed to developing an organization for everyone, and women physicians were welcomed early on. Three women physicians even served as the presidents of various anesthesia organizations early in the formation of the present national organization. This acceptance of women was to change as medical education and practice evolved to embrace scientific medicine, after the Flexner Report of 1910 documented the deficiencies of American medicine. Mrs McMechan made the most important contributions by a woman because she cared totally for Dr McMechan, after he experienced disabling and very severe arthritis. He became dependent on his wife for most activities, including the simple act of eating. He could not function without her; she kept him going physically for another 27 years after the onset of his very debilitating illness. After her husband's death in 1939, Mrs McMechan served an executive function, keeping the organization going and maintaining production of the journal. This article also briefly discusses the life of the first woman physician to publish an article in A&A, Frances Edith Haines, MD, of Chicago. Haines published several articles in the journal; the first was in 1922, in the second journal issue. She was the president of the Mid-Western Association of Anesthetists, an affiliated organization, in 1926. She also served in World War I as a contract physician anesthetist for the US Army; she was the first woman contract surgeon to go overseas, to Limoges, France. Her adventure-filled and bold life changed as she aged and developed financial problems. She tried, but failed, to get financial help from the government and the military for her war service, and she died in 1966. These women are examples of women physicians involved with the journal, as it began in 1922. As the number of women physicians has increased recently, some past problems, such as difficulty with getting admitted to medical schools, for example, have improved. However, there are still many issues for women in medicine, including in our specialty., Competing Interests: The author declares no conflicts of interest., (Copyright © 2022 International Anesthesia Research Society.)

Technological innovation has been closely intertwined with the growth of modern anesthesiology as a medical and scientific discipline. Anesthesia & Analgesia, the longest-running physician anesthesiology journal in the world, has documented key technological developments in the specialty over the past 100 years. What began as a focus on the fundamental tools needed for effective anesthetic delivery has evolved over the century into an increasing emphasis on automation, portability, and machine intelligence to improve the quality, safety, and efficiency of patient care., Competing Interests: Conflicts of Interest: See Disclosures at the end of the article., (Copyright © 2022 International Anesthesia Research Society.)

The year 2022 marks the 100th anniversary of Anesthesia & Analgesia, the longest-running anesthesiology publication in the world. Founded in 1922 as Current Researches in Anesthesia & Analgesia by the visionary and charismatic Francis McMechan, MD, the journal served as a reliable mirror for the key scientific and political issues facing the nascent specialty of anesthesiology. Under the leadership of 6 subsequent Editors-in-Chief over the ensuing century-Howard Dittrick, MD; T. Harry Seldon, MD; Nicholas M. Greene, MD; Ronald D. Miller, MD; Steven L. Shafer, MD; and Jean-Francois Pittet, MD-Anesthesia & Analgesia has grown in size, circulation, and impact. Today, it remains a formidable voice in the global anesthesia community., Competing Interests: Conflicts of Interest: See Disclosures at the end of the article., (Copyright © 2022 International Anesthesia Research Society.)

The theoretical and practical foundations of modern oxygen therapy were established during the first half of the 20th century. John Henry Evans, MD, inaugural chairman of the Board of Governors of the International Anesthesia Research Society (IARS), was an early pioneer in this field. Challenging the conventional wisdom that high concentrations of oxygen were harmful when inspired over long periods, Evans advocated the continuous and extended administration of 100% oxygen in a wide range of conditions, using special apparatus developed by the Toledo Technical Appliance Company (later, the McKesson Appliance Company), which incorporated a tight-fitting facemask or nasal inhaler. In doing so, Evans became embroiled in a conflict with Alvan Barach of Columbia University College of Physicians and Surgeons, which would take nearly a decade to resolve. Additionally, Evans experimented with the subcutaneous injection and intravenous infusion of oxygen, reporting significant benefits of the former in several acute inflammatory conditions, as well as a variety of chronic ailments. While these contributions have largely been forgotten, Evans expanded the remit of anesthesiology beyond the operating theater and the original charter of the IARS and helped lay the foundations for the rational use of oxygen as a therapeutic agent in all areas of medicine., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 International Anesthesia Research Society.)

As the practice of pediatric anesthesiology grew in the early 20th century, Anesthesia & Analgesia (A&A) became the most important practical resource of pediatric fundamentals for general anesthesiologists. With continued growth in the mid-20th century, focus then shifted to complex cases performed by dedicated pediatric anesthesiologists. To this day, A&A continues to serve as a crucial forum for our subspecialty as it matures. The International Anesthesia Research Society (IARS) also remains pivotal in addressing the crucial questions of modern practice, such as the recent founding of the SmartTots initiative to investigate the potential neurotoxicity of anesthetics in children. While A&A celebrates 100 years of publication, we reflect upon pediatric anesthesiology's evolution and the impact of the IARS and A&A on pediatric anesthesiology's scholarship, clinical practice, and professionalization., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 International Anesthesia Research Society.)

For decades, the term ether rush was synonymous with the practice of short-term anaesthesia, among patients and doctors. The term was first used shortly after the discovery of the anaesthetic properties of ether by Hamburg-based physician Elias Salomon Nathan in an article about the newly discovered ether anaesthesia. Decades later, the surgeon Paul Sudeck, who also worked in Hamburg, also described an anaesthetic technique he practiced as an ether rush and met with great approval from his surgical colleagues, as well as for his anaesthetic mask developed for carrying out the ether rush and the anaesthetic dropper, specified for this purpose.Sudeck did not want to be regarded as the inventor of the special anaesthetic technique and repeatedly pointed out that his procedure had already been described and applied before him, but was forgotten again. Nevertheless, Sudeck's ether rush remained a well-known, widespread analgesic method in German-speaking countries until the end of the 1940s, and it proved its worth many times during the World War. After 1945, when ether lost its pre-dominant role as an inhalation anaesthetic and was replaced by other, new agents and short-acting i. v. administered analgesics, the ether rush was also fell into oblivion and was no longer used.Against the background of the first successfully performed ether anaesthesia on October 16th, 1846 - 175 years ago - at the Massachusetts General Hospital in Boston, the description of the ether rush should be recalled in this context., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Boston dentist William T. G. Morton secured a provisional English patent for etherization in December 1846. The full patent specification was submitted 6 months later, and the patent was sealed on June 18, 1847. The enrolled copies of the provisional and full patents, which are held in The National Archives, London, have not been previously documented in the anesthesia literature. We review the communications between Boston and London regarding the patent for etherization, the possibility that preliminary discussions and trials of etherization may have been conducted in London before the earliest known application of the discovery for a dental extraction on December 19, 1846, and the role of the American lawyer James Augustus Dorr, who was Morton's agent in the United Kingdom., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 International Anesthesia Research Society.)

Introduction: The administration of sulphuric ether by William Thomas Green Morton (October 16, 1846) is considered the medical breakthrough of fastest worldwide spread in history. Unfortunately, the current information available about the evolution of the specialty is still limited, particularly in Central America. Objectives: Deepen in the Anesthesiology history in Latin America. Method: Historical qualitative research where the general methods of theoretical level are used to analyze the documentary review. Results: It was on March 11th 1847 when the sulphuric ether was applied for the first time in Cuba and Latin America by the MD Vicente Antonio de Castro y Bermúdez. The news of this event constituted the first publication about anesthesia in our country. It is proved that after Cuba followed Uruguay and Brazil. It is unprecedented in the investigation the discovery of the relation between MD Sansores, from Mexico, and Cuba; through the different papers published in the Cuban Economic Repertoire of Medicine. Conclusions: In Cuba was the first time the sulphuric ether anesthesia was applied in all Latin America. Missing information in the international publications regarding the anesthesiology history in Latin America has been clarified. Through this paper work was demonstrated the links between Cuba and Mexico by the scientific production of the Mexican MD José Matilde Sansores. [ABSTRACT FROM AUTHOR]

John S. Lundy was able to accomplish three major goals during the early years of his stewardship of the section on anesthesia of the Mayo Clinic. In 1925, Lundy established the first anatomy lab at the Mayo Clinic. He believed that the lab would serve as a useful tool for teaching residents as well as research into regional anesthetic techniques. Second, Lundy desired to advance the science of anesthesiology. Lundy developed the concept of balanced anesthesia, pioneered the introduction of barbiturates to the practice of anesthesia, developed anesthesia section services for the use of ventilators, ventilator vests, oxygen tents, and nasal oxygen supplementation. Lastly, in 1935, he established the nation''s first blood bank. Lundy and Ralph Tovell had the opportunity to do pioneering work in transfusion medicine, which led to an improvement in the quality of service, and patient safety. These three major accomplishments provided Lundy with abundant scientific material to present to the American Medical Association (AMA) in Chicago. These trips to Chicago allowed him to gain the ear of Olin West, Morris Fishbien, and James E. Pallin. Lundy was able to successfully lobby in 1939 for the creation of a section of anesthesia within the AMA. In 1940, Lundy′s dream came true with the recognition of anesthesia as a specialty by the AMA.

At the outbreak of World War II (WWII), anesthesiology was struggling to establish itself as a medical specialty. The battlefield abruptly exposed this young specialty to the formidable challenge of mass casualties, with an urgent need to provide proper fluid resuscitation, airway management, mechanical ventilation, and analgesia to thousands. But while Europe was suffering under the Nazi boot, anesthesia was preparing to rise to the challenge posed by the impending war. While war brings death and destruction, it also opens the way to medical advances. The aim of this study is to measure the evolution of anesthesia owing to WWII. We conducted a retrospective observational bibliometric study involving a quantitative and statistical analysis of publications. The following 7 journals were selected to cover European and North American anesthesia-related publications: Anesthesia & Analgesia, the British Journal of Anaesthesia, Anesthesiology, Schmerz-Narkose-Anaesthesie, Surgery, La Presse Médicale, and The Military Surgeon (later Military Medicine). Attention was focused on journal volumes published between 1920 and 1965. After reviewing the literature, we selected 12 keywords representing important advances in anesthesiology since 1920: "anesthesia," "balanced anesthesia," "barbiturates," "d-tubocurarine," "endotracheal intubation," "ether," "lidocaine," "morphine," "spinal anesthesia," "thiopental," "transfusion," and "trichloroethylene." Titles of original articles from all selected journals editions between 1920 and 1965 were screened for the occurrence of 1 of the 12 keywords. A total of 26,132 original article titles were screened for the occurrence of the keywords. A total of 1815 keywords were found. Whereas Anesthesia & Analgesia had the highest keyword occurrence (493 citations), Schmerz-Narkose-Anaesthesie had the lowest (38 citations). The number of publications of the 12 keywords was significantly higher in the postwar than in the prewar period (65% and 35%, respectively; P < .001). Not surprisingly, the anesthesiology journals have a higher occurrence of keywords than those journals covering other specialties. The overall occurrence of keywords also showed peaks during other major conflicts, namely the Spanish Civil War (1936-1939), the Korean War (1950-1953), and the Vietnam War (1955-1975). For the first time, this study demonstrates statistically the impact of WWII on the progress of anesthesiology. It also offers an objective record of the chronology of the major advances in anesthesiology before and after the conflict. While the war arguably helped to enhance anesthesiology as a specialty, in return anesthesiology helped to heal the wounds of war., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 International Anesthesia Research Society.)

A 19th century physician was crucial to the establishment of 2 medical specialties-anesthesiology and public health. Everyone whose interest in public health has increased in the last year will be amazed at Dr John Snow's career in anesthesiology. Those who recognize him as the first full-time physician anesthetist will be struck by his development of medical mapping during the Cholera Pandemic of 1848, resulting in one of the fundamental techniques of epidemiology and public health that has continued through today. Snow's accomplishments in anesthesiology and epidemiology reflected a concatenation of science, focus, and creativity. His training in the early 19th century integrated science, medicine, and his keen interest in respiratory physiology. His early clinical exposure to colliery workers in Newcastle was likely influenced by the earlier development of pneumatic medicine. He was committed to the notion that chemistry, especially the use of medicinal gases, would be transformative for medicine. Thus, he was "primed" when the news of the American anodyne ether reached London in 1846. When the third cholera pandemic reached London shortly thereafter, in the fall of 1848, his academic and practical understanding of gas chemistry and pharmacology, respiratory physiology, and anesthetic agents led him to question the popularly promulgated miasma-based theories of transmission. His methodical investigations, research, and perseverance were mirrored in his scholarly work, numerous presentations, and public advocacy. He articulated many scientific principles essential to the early practice of anesthesia-anesthetic potency, quantitative dosing of anesthetic agents, engineering principles required for conserving the latent heat of vaporization, and minimizing the contribution of anesthetic equipment to airway resistance. He moved easily and methodically between these worlds of physiology, chemistry, engineering, clinical medicine, and public health. In his role as the first medical epidemiologist, Snow understood the power of medical mapping and the graphic presentation of data. He was a pioneer in 2 nascent fields of medicine that were historically and remain contemporarily connected., Competing Interests: The author declares no conflicts of interest., (Copyright © 2021 International Anesthesia Research Society.)

Fifty years ago, on August 1, 1971, William A. Lell became the first cardiac anesthesia fellow at Harvard's Massachusetts General Hospital (MGH) Department of Anesthesiology, training with the world's first group of anesthesiologists whose clinical practice, teaching, and research efforts were exclusively devoted to cardiac anesthesia. Lell's early interest in cardiovascular medicine and how mentors, particularly at the MGH, influenced his early career development are recounted. The challenges a young pioneer faced in establishing and maintaining an academic cardiac anesthesia program during the initial and rapid growth of an exciting new subspecialty are described. Dr Lell's experience emphasizes the importance of seizing new opportunities and establishing meaningful working relationships with colleagues based on mutual trust as fundamental to successful career development and research in a new medical subspecialty., Competing Interests: The author declares no conflicts of interest., (Copyright © 2021 International Anesthesia Research Society.)

Dr. Anne Marie Lynn (1949-present), Professor Emeritus of Anesthesiology, Pain Medicine, and Pediatrics at the University of Washington, Seattle, was one of the most influential women in pediatric anesthesiology of her generation. Dr. Lynn embodies the spirit of discovery and advancement that have created the practice of pediatric anesthesiology as we know it today. A pioneer in pain medicine pharmacology, particularly morphine and ketorolac, her research transformed pediatric anesthesia, pediatric pain medicine, and pediatric intensive care medicine. Through her journal articles, book chapters, national and international lectures, mentoring of residents, fellows, and faculty, and leadership in the Society for Pediatric Anesthesia, she inspired a generation of women and men physicians by demonstrating that gender should not be a barrier to undertaking roles once only held only by men. In 2017, for her many contributions, she was awarded the Society for Pediatric Anesthesia's Myron Yaster lifetime achievement award., (© 2021 John Wiley & Sons Ltd.)

Gertrude Gerrard is a relatively unknown but important early nurse anesthetist in the United Sates in the early part of the 20th century. She was in the first class to graduate from the Peter Bent Brigham Hospital (PBBH) School of Nursing in Boston, Massachusetts. After graduating from nursing school, she participated in anesthesia training with Walter Boothby and became the first nurse anesthetist at the PBBH. In 1917 she was included in a group of medical professionals from the Harvard hospital system to serve in the medical corps in France during World War I. While there she worked with surgeon Harvey Cushing and this professional relationship continued back in Boston. She also was the first nurse anesthetist at Strong Memorial Hospital in Rochester, New York from 1925-1927. She returned to Boston in 1928 and continued as the chief anesthetist at PBBH until leaving in 1946 during a departmental staffing transition after WWII., Competing Interests: Name: Michael A.

In 1934, Gertrude Fife, President of the National Association of Nurse Anesthetists (NANA) sought to elevate the standards of anesthesia practice and standardize the education of nurse anesthetists. NANA members located schools, developed education standards and a school approval process, that eventually led to creation of the Council on Accreditation of Nurse Anesthesia Educational Programs (COA) in 1975. Examination of historical documents demonstrated that COA developed into a well-known accreditation agency recognized by both governmental and non-governmental organizations, enhancing the standards of anesthesia education and promoting high-quality educational programs.

The aim of this work is to identify the most influential initial clinical studies that fomented important developments in anesthesiology over the past 50 years. Studies fomenting new development can be selected using vastly different approaches and, therefore, might provide diverse outcomes. In the present work, two basic aspects of study assessments - the stage of development (eg, generation of idea, preclinical studies, clinical trials) and the method of selection (eg, committee vote, various types of citation analysis, method of finding the invention disclosure) - were chosen according to the following model. The stage of development: the initial clinical studies demonstrating the basic advantage of an innovation for providing anesthesia. The method: a combination of two factors - the study priority in terms of the time of its publication and the degree of its acknowledgement in the form of citation impact; the time of study publication was regarded as a primary factor, but only if the study's citation count was =/>20. The initial high-impact studies were selected for 16 drug-related topics (ketamine, isoflurane, etomidate, propofol, midazolam in anesthesia, vecuronium, alfentanil, atracurium, sevoflurane, sufentanil, rocuronium, desflurane, ropivacaine, remifentanil, dexmedetomidine in anesthesia, and sugammadex), and 9 technique-related topics (ultrasound-guided peripheral nerve block, capnography in anesthesia, target-controlled intravenous anesthesia, pulse oximetry in anesthesia, total intravenous anesthesia, transesophageal echocardiography in anesthesia, combined spinal-epidural anesthesia, and bispectral index). Twenty-five studies were designated the first high-impact studies (one for each topic); 16 are drug-related and 9 are technique-related. Half of the first high-impact studies had a citation count of =/>100, (range: 100 to 555). The citation count of the other half of high-impact studies did not reach the 100-citation threshold (range: 41 to 97). If a selected first high-impact study had a citation count <100, a next-on-timeline, additional study with citation count =/>100 was also selected; (range: 100 to 344). The present results show that an initial high-impact clinical study on a new development in anesthesiology can be determined and that related citations usually vary from one hundred to five hundred., Competing Interests: The author reports no conflicts of interest in this work., (© 2021 Kissin.)

Background: Within the history of intravenous anesthesia, barbiturates represent a chapter of considerable importance. Although the reference barbiturate thiopental had several limitations, it dominated the scene of the intravenous anesthesia until the mid-1980s, when propofol was introduced on the market. In the meantime, several barbiturate derivatives were placed on the market and abounded. This work is aimed at evaluating the clinical impact of the barbiturate derivatives methitural, analyzing the reasons for its rapid abandonment, in the late 1950s., Methods: A systematic methodology of the search was associated with a descriptive analysis of the bibliography found. A computer-operated search strategy using Medline and Google Scholar databases was implemented. The algorithm was composed by using the words "Diogenal" OR "Thiogenal" OR "Methitural" OR "Metigenal" OR "Neraval" including biochemical and marketed terms. A manual search of the sources was carried out, and precise inclusion and exclusion criteria were established. The narrative synthesis was conducted taken into account the historical context of anesthesia., Results: The database search yielded 3645 records. Nineteen records were identified through other sources. After duplicates removing (n = 238), and exclusion of not pertinent 3027 records, 314 full-text articles were assessed for eligibility. Of those, other 225 papers were excluded and 89 articles were included in the qualitative synthesis., Conclusion: Although methitural could be useful in particular surgical settings such as short-acting surgery, and in patients with liver diseases, a limited advantage over thiopental, and its scarce market diffusion due to increased costs, have limited its use. Through a critical analysis of literature, the lack of high-quality studies does not allow us to draw definitive conclusions on the drug., (Copyright © 2020 Anesthesia History Association.

Letheon was the commercial name that Boston dentist William T. G. Morton chose for his ether-based "preparation" that was inhaled to produce insensibility during surgical and dental procedures. The multiple editions of Edward Warren's Some Account of the Letheon (1847) as well as Nathan P. Rice's Trials of a Public Benefactor (1859) provide the only known accounts of the meeting hosted by the physician Augustus A. Gould at which the name Letheon was chosen. Neither Warren nor Rice mentions when the meeting occurred. In all likelihood, it was held at some point in a three-week period from mid-November to just short of December 9, 1846, the publication date of the earliest known reference to the name. The absence of the word Letheon in Morton's public notices around the end of November 1846 or, indeed, in any document until his December 9 advertisement in The Boston Medical and Surgical Journal suggests a later date for the meeting than has been previously reported., (Copyright © 2020 Anesthesia History Association.

Pioneering anesthesiologists Paul Wood, M.D., and Arthur Guedel, M.D., were Hoosiers who migrated from America's Heartland to opposite coasts. Dr. Wood moved east to New York in 1913; Dr. Guedel, west to California in 1928. By 1962, each pioneer had been honored with a namesake anesthesia museum. Fast-forwarding 55 yr, two young anesthesia historians, California's Jane Moon, M.D., and Pennsylvania's Melissa Coleman, M.D., met at the 2017 International Symposium of the History of Anesthesia in Boston. Today, these women are chairs of the Wood Library-Museum's Archives and Museum Committees, respectively. As the newest authors of "Anesthesiology Reflections," Drs. Coleman and Moon leave their coastal states semiannually for board meetings at the Wood Library-Museum of Anesthesiology, returning as legacies of Drs. Wood and Guedel…back to the American Heartland., (Copyright © 2020, the American Society of Anesthesiologists, Inc. All Rights Reserved.)

Irwin B. Wilson and anesthesiologist Richard J. Kitz found the enzyme acetylcholinesterase to be inactivated in two steps by covalently acting molecules resembling acetylcholine in structure. Such molecules rapidly and reversibly bind to the active site of the enzyme. Next, the reversible complex undergoes covalent fixation at a characteristic rate. The Kitz-Wilson phenomenon applies to many cases of time-dependent enzyme inhibition. Experimental data are commonly graphed in linear fashion on "Kitz-Wilson plots". Kitz also contributed to a gas chromatography-mass spectrometry assay for acetylcholine that was suitable for the nonbiological detection of that neurotransmitter in mammalian brain., (Copyright © 2020 Anesthesia History Association.

John Gillies was the founding head of the Department of Anaesthetics at the Royal Infirmary of Edinburgh, which began in 1940. An astute educator, he was instrumental in establishing anesthesia as a medical specialty, on equal footing with surgery, from the start of the National Health Service in 1948. Gillies' kudos attracted medical graduates from the UK, USA and Canada to work in his Department. The excellence of his teaching and mentoring may be judged from the fact that no less than seven of his protégés became professors of anesthesia/anesthesiology. This paper identifies these seven professorial protégés and reviews their careers. Reasons for the successful consequences of John Gillies' tutelage are considered., Competing Interests: Declaration of Competing Interest None., (Crown Copyright © 2020. Published by Elsevier Inc.

An ex-employee of a Newark straw hat factory, 15-year-old Robert Alden Fales battered the factory's cashier Thomas Haydon on the head multiple times with a wooden staff. Fales then applied a chloroform-soaked handkerchief to Haydon's nose until the cashier stopped moving. Arrested and convicted of murder, Fales had his death sentence commuted to life imprisonment. At 23 years of age, the criminal chloroformist died in jail from tuberculosis., (Copyright © 2020 Anesthesia History Association. Published by Elsevier Inc. All rights reserved.)

The definitive account of the life and work of Horace Wells, the dentist from Hartford, Connecticut, who experimented with nitrous oxide anesthesia in 1844, is that published by W Harry Archer for the centenary of Wells's work. A major source of original material was a collection of letters, by Wells and others, that Archer found in the house in Hartford, Vermont, in which Wells was born. In later support for Wells being better recognized for his role in the introduction of general anaesthesia, Richard J Wolfe and Leonard F Menczer published a collection of essays in 1994. However, their preparation was hampered by their (mis)understanding that the 'Archer' letters (which were lodged in the Pittsburgh University Library) were "missing", a belief which continued, but has been disproved by a new author. Before his death, John Bunker encouraged his anthropologist daughter, Emily, to continue a project he had been planning on the history of anesthesia, and the result is a new book, "Horace and Elizabeth: Love and Death and Painless Dentistry". First and foremost Ms Bunker has discovered that the Archer Letters are very much available, and has been greatly helped by the University of Pittsburgh Library in producing her book. She has used reproductions and transcriptions of the letters (some previously unpublished) and other contemporary documents to illustrate Wells's role in the great discovery. Some of the material, especially from before the 'Colton' demonstration of 1844 is remarkable; it is almost like hearing the story from Wells himself., Competing Interests: Declaration of Competing Interest I was one of the contributor's to Wolfe & Menczer's I Awaken to Glory and know just how much they regretted not being able to consult the letters collected by Archer and stored in Pittsburgh. Also, I have corresponded with Ms Bunker and provided advice on historical and related matters, but played no part in the production of this new book., (Copyright © 2020 Anesthesia History Association.

The letters between Emery Andrew Rovenstine, MD (1895-1960), and Arthur Ernest Guedel, MD (1883-1956), are a window into the personalities and politics of the creation of American anesthesiology. The ambition of these men, both personal and professional, lay at the heart of their sacrifices and successes. Their correspondence unmasked common struggles and foibles, humanizing these giants of our field. Notably throughout the letters, Rovenstine, as the junior partner, wrestled with Guedel's advice to temper personal ambition for the collective good. Over time, their relationship matured, and the junior eclipsed the senior. Still, at various points in his career, Rovenstine was censured for self-promotion by leaders in anesthesiology and the general medical community. These moments brought to light issues of continued relevance today: inner tension between individual and group ambition, and professional friction between academic and political priorities in anesthesiology. In the end, it was an unapologetic blend of ambition for self and ambition for the specialty that allowed Emery Rovenstine to make his unique imprint on American anesthesiology.

Buenos Aires' González Varela Library-Museum exhibits a possibly unique Lundy Rochester Model of Heidbrink Kinet-O-Meter anesthesia machine. Surveyed anesthesia libraries or museums reported no identical model of anesthesia machine or literature specific to same. Machine markings and the flowmeter patent helped narrow the year of manufacture to circa 1936., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 Anesthesia History Association.

The period during and after World War II saw enormous changes in the practice and status of anaesthesia, as well as in female participation. This article offers an account of three South African (SA) women who trained in anaesthetics before and during the War and participated in these changes. By the mid-1960s, they presided over the three independent anaesthetic departments at Johannesburg's three main teaching hospitals, teaching generations of junior doctors. The first woman to register as a specialist anaesthetist in SA, Miriam (Mollie) Barlow, broke the glass ceiling in her own career by lobbying for the professional rights of medical women, although working within the constraints of the medical and political establishment. She also contributed to important SA research on malignant hyperthermia. Hilde Ginsberg collaborated with Barlow in the 1950s, reducing intraoperative and perioperative mortality at Coronation Hospital, and fought for key interventions in anaesthetic practice and policy through the South African Society of Anaesthetists (SASA), becoming its most long-serving and honoured female member. Kathleen Barbara Vetten's exemplary career in academic medicine, including pioneering animal research (developing anaesthetic techniques for open-heart surgery in dogs and protocols for liver transplantation in primates) and a successful operation to separate craniopagus twins, shows both the achievement of and limits to female achievement at the end of this period. This article also offers a short account of factors that hindered black women from entering anaesthesia training, contributing to this history before the 1990s.

This paper is the continuation (Part 2) of an extensive, critical reappraisal of the international historiography on modern anesthesia and its technology. The first paper of this series provided general definitions, backgrounds and an update on recent research on one aspect of this topic: the history of professionalization / specialization (Part 1). 1 This paper goes on to provide a first, international comparison of entire anesthesia devices and on the history of nitrous-oxide-based anesthesia (c. 1900-1930s). Results: A comparative chronology of internationally recognized milestones of entire anesthesia machines does not suggest significant differences between the nations of continental Europe on one side, or the USA and Britain on the other. The international historiography on one of the key techniques for which these devices were designed (nitrous-oxide-based anesthesia), is likewise demonstrably biased. These findings are further evidence that a frequently held hypothesis, which suggests national dominances in these fields, is incorrect. Contributing factors and wider contexts of this phenomenon can be further confirmed: These are an under-recognition of non-Anglo-American (particularly continental-European) and of primarily surgical contributions; contemporary international conflicts and inter-professional demarcation disputes. In addition, it can be shown that these phenomena had already started around the same time (c. 1900s-1930s). There also is evidence to suggest that they were at times reciprocal and quite deliberate. The author illustrates and argues that the currently prevalent historiography on modern anesthesia requires a thorough reassessment. This should be based on a perspective of internationalism and transdisciplinary reciprocity and should recognize much broader historical contexts., Competing Interests: Declaration of Competing Interest The author declares that he has no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Crown Copyright © 2020.

This paper is the first in a series of publications. These investigate, whether important elements of the historiography of anesthesia require a critical reappraisal. A systematic, combined presentation, contextualization and assessment of recent European research is provided. This includes the author's own findings. These emanate from two extensive projects. They combine very recent findings with results of earlier research, conducted by the author and numerous collaborators over the last 18 years. The findings represent an ever increasing and ever more robust body of evidence. They add an important new element to our international historiography. As an introduction, several definitions will be given for criteria, which designate "modern" anesthesia and its technology. On one of these criteria, the history of professionalization and specialization, a short overview will be given. This will be followed by an overview of general contexts, key features and early achievements of anesthesia-related technology. All results will be compared with a currently dominating narrative: This alleges "dominance" of US-American and British pioneers and developments. Apparent biases and inconsistencies are identified. These suggest that our current, international historiography of anesthesia may require a critical reassessment. Three subsequent articles will focus on specific aspects of anesthesia technique and technology. Their results likewise suggest a history of internationalism and trans-disciplinary reciprocity, rather than of national dominances. Further investigations will aim to ascertain the nature and extent of potential interactions, which may nowadays be underrecognized., (Copyright © 2020 Anesthesia History Association.
