Ethyl chloride was first used as a general anaesthetic in 1847, by Johann Ferdinand Heyfelder (1798-1869), a German surgeon. Once ethyl chloride became readily available, it was again taken up as a general anaesthetic in the late 1890s (USA). Ethyl chloride evaporates very quickly so that when it is sprayed onto the skin it produces very cold temperatures. “Refrigeration anesthesia”, or cryoanesthesia, refers to the anesthesia produced when the skin is significantly cooled.Due to its rapid onset, ethyl chloride was often used to induce general anaesthesia. It would be followed by a second anaesthetic, such as ether or nitrous oxide, which would be used for the remainder of the procedure.

Dr. Curt Schimmelbusch (1860-1895), a German physician, designed his original mask around 1889 while an assistant surgeon. Surgical assistants were often assigned the task of delivering the anesthetic. During anesthesia it was not uncommon for ether and chloroform to get onto the patient’s skin, causing irritation. Chloroform can even cause burn-like reactions. Schimmelbusch designed the rim of his mask so that both sides curve away from the patient’s face to form a kind of trough. He intended the trough-like rim to collect excess anesthetic that would otherwise have trickled onto the patient’s face. To anesthetize a patient, gauze was stretched over the metal bars and fastened in place by the hinge. The mask was placed over the patient’s nose and mouth, and the anesthetic was applied in drops or lightly poured onto the gauze so that the patient breathed in evaporated anesthetic as well as air. This type of mask is sometimes still used today for ether anesthesia in developing countries when other means are not available. (Wood Library Museum of Anesthesiology) This particular object is a modified version of Schimmelbusch's design, known as Chadborn's modification.Oval shaped chromium plated mask with two metal strips linked front to back and side to side to create a dome. An oval shaped mobile wire frame is attached to the lower part of the mask by a hinge at the back, approximately two inches from the lip of the metal handle. A "U" shaped bit of metal is attached to the front of the mask which acts as a clip to fasten the wire frame to the lower section of the mask.anaesthesia

Chevalier Jackson was a surgeon who designed this laryngoscope. Jackson contributed a number of important innovations to direct laryngoscopy, while developing a unique mastery of the technique. Ultimately, he combined this endoscopic proficiency with open surgical techniques.The U-shaped laryngoscope comprises a moulded handle and a long endotracheal insert which has a small connector to allow for a light to illuminate the patient's throat. The item is chrome-plated.Engraved on connecting shaft: Jackson's Laryngoscope, 1901.laryngoscope, chevalier jackson, endoscope, anesthesia, distal illumination, chrome, 1901, jackson's

The image, without a blackened out background was reproduced on page 21 in 'Practical Anaesthesia'. Practical Anaesthesia was the first text book on anaesthesia produced in Australia. Geoffrey Kaye was one of the contributors to this book, which included a foreword by F.H. McMechan, Secretary General, International Anesthesia Research Society. Blood pressure measuring enabled medicine to develop a greater understanding of shock and begin to develop more appropriate measures for resuscitation. Shock was not really understood until the introduction of routine blood pressure measuring in the early 20th century.This item is historically significant because it is a rare photograph of Dr Geoffrey Kaye, as well as being reproduced in Practical Anaesthesia, the first textbook on anaesthesia to be produced in Australia.Black and white photograph showing Dr Geoffrey Kaye during a demonstration of monitoring during anaesthesia in 1932.

Mask used for administering ether anaesthesia. This mask also has a carbon dioxide inlet tube. Carbon dioxide was found to promote deeper breather which assisted in attaining faster anaesthesia. The mask was designed by an American anaesthetist James Tayloe Gwathmey, (1863-1944). Gwathmey invented a range of anesthesia equipment. In 1904, he introduced this mask as one part of a resuscitation apparatus. Gwathmey modified an existing mask to more closely fit the contours of the face. The holes in the rim allow for oxygen to be delivered for resuscitation or for the delivery of a combination of oxygen and anaesthetic. Wire framed mask in tear shape. There is a hinged top bracket which allows for a piece of flannel or domette to secured to the mask, onto which the ether would be administered. There is an inlet tube near the hinged bracket to allow for the administration of CO2 or oxygen and the rim is pierced with holes.james tayloe gwathmey, ether, anaesthesia, anesthesiologist, carbon dioxide, oxygen

The De Ford Inhaler was introduced in 1913 and was designed to allow anaesthesia to continue through the nose while dental surgery was happening.This inhaler is composed of metal and rubber. The oral mask and rubber covered nasal mask are connected to a curved rubber covered support that was placed on the patient's forehead to hold the inhaler in place. The gas was administered via a long tube; the terminus designed to allow for the placement of a vial containing the anaesthetic drug and a rebreather bag mount.

Professor Arthur Barrington (Barry) Baker was the first Australian anaesthetist to gain a DPhil in anaesthesia. He completed his DPhil at Oxford University at the Nuffield Department of Anesthesia in 1971, titled, Physiological Responses to Artificial Ventilation. The Waveform Ventilator is the machine developed to illustrate his DPhil. The waveform ventilator was used in several scientific studies on 'the effects of varying inspiratory flow waveforms and time in intermittent positive pressure ventilation (IPPV)', published in the 'British Journal of Anaesthesia'. Professor Arthur Barrington Baker had an extensive career in research and clinical practice including holding the position as the Nuffield Professor of Anaesthetics at Sydney university (1992 - 2005) and also as the Dean of the Australian and New Zealand College of Anaesthetists (ANZCA) (1987-1990).The variable waveform ventilator is of national significance, due to its association with Professor Arthur Barrington Baker (Prof. Baker) the first Australian academic anaesthetist, and the representation of historical social themes and research and design, in anaesthesia. Historic significance – It is a rare type of ventilator in good condition and well provenanced. It is a tangible record of the beginning of the long established and distinguished career of Prof. Baker, the first anaesthetist in Australia to gain a DPhil. Prof Baker has a strong involvement in the Australian and New Zealand College of Anaesthetists (ANZCA) organisation. The object is a product of Prof Baker’s Doctorate of Philosophy (DPhil) on respiratory physiology and is associated with the prestigious Oxford University and the well-known Nuffield Department of Anaesthetics. It also represents the social theme of migration to England from Australia in the 1960s and 1970s to access and experience academic and artistic opportunities limited in Australia at the time. Scientific Value – The object is of scientific value as it offers major potential for education and interpretation in anaesthesia. Although ventilators are common equipment, this specific design and construct prototype is one of a kind, designed and used specifically for research purposes. A rectangular shaped object on a trolley with four wheels. The top half of the object consists of two panels, one of cream coloured painted wood, the other black plastic, both containing several dials of different shapes and sizes. The wood surface also contains several gauges and a safety pressure clear plastic box. The plastic surface also contains a pin board. The bottom half of the object consists of two shelves. The whole object's perimeter is lined with perforated metals. The top wooden surface has several metal pieces of equipment and a long tube. The rear of the object contains numerous types of tubing and wire, a gas cylinder and two leather straps with buckles. The bottom half of one side of the objects has 3 electrical power outlets.Waveform Generator, Drs Colliss N Cowie, Dr Baker Dr Murray Willson, Dr Babbington, Safety Pressure, Error POS F/B, Position, Feedback, Set Balance, Reset, Full Stroke, Velocity, Converter Current, line Pressure, Low Pressure, Bias Pressure, Start, Stop, Stop, Reset Press, Max Press, W/G Output, A/CRO B/2.baker, arthur barrington, baker, barry, professor, academic anaesthetist, oxford university, nuffield department of anaesthesia

Dr. Dai Davies presented this Goblet as a gift to the Faculty as the first appointed Burnell-Jose visiting Professor, Postgraduate Committee in Medicine, S.A. May - June 1976. At the time, Dr Davies was the Consultant Anaesthetist St George's Hospital, London and during this event was elected to Honorary Fellowship of the Faculty of Anaesthestists, Royal Australasian College of Surgeons. The Burnell-Jose Visiting Professorship commenced in Adelaide in 1975 in honor of Mary Burnell, the first woman Dean of the Faculty from 1966 to 1967 and the first woman President of the Australian Society of Anaesthetists in 1955. Very few women had assumed major anesthesia roles in the world during this period. The Goblet's provenance is supported by an original booklet, which certifies its origin from Chichester Cathedral (1075), Sussex, England. In 1975, a limited edition of 600 goblets were commissioned by the Dean and Chapter of Chichester Cathedral, Reverend Walter Hussey, to commemorate the ninth century of the Foundation. This Goblet is number 46 of the edition and the booklet is signed by Walter Hussey. The Goblet is historically associated with Chichester Cathedral and Walter Hussey, who was a great patron of the arts during the 1970's.Solid silver, with pure gold overlaying the modeled stem and interior of the cup.

For inhalation anesthesia, a gag may be used to keep a patient’s mouth open. In 1910, Edward C. Sewall, M.D. (1875-1957), published a description of a mouth gag which he designed, stating that it was a modification of the earlier Hartman gag. Dr. Sewall’s gag caught the eye of anesthesiologist S. Griffith Davis, M.D.(1867-1934), who modified it further for use in tonsillectomies. In 1912, a description of Dr. Davis’ gag was published by the prominent surgeon, Harvey W. Cushing, M.D. (1869-1939.) During a visit to the United States in 1921, the English anesthesiologist Henry E. G. Boyle (1875-1941) was impressed by the Davis gag, and bought one. He published two descriptions of it the following year, and again in the 1923 edition of his influential textbook. It became better known as the Boyle, or Boyle-Davis, gag. Today the gag popularized by Boyle continues to be made by many equipment manufacturers. It consists of a frame that incorporates a handle, together with a selection of tongue depressors, called blades, in various sizes. The paddle of depressor would hold the patient’s tongue and lower jaw, while the two, rubber-lined extensions at the top of the frame supported the patient’s upper teeth. From the 1920s through the 1990s, there have been at least 20 further modifications of the Davis gag. https://www.woodlibrarymuseum.org/museum/davis-gag/ This mouth gag was donated to Flagstaff Hill Maritime Village by the family of Doctor William Roy Angus, Surgeon and Oculist. It is part of the “W.R. Angus Collection” that includes historical medical equipment, surgical instruments and material once belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) as well as Dr Angus’ own belongings. The Collection’s history spans the medical practices of the two Doctors Ryan, from 1885-1926 plus that of Dr Angus, up until 1969. ABOUT THE “W.R.ANGUS COLLECTION” Doctor William Roy Angus M.B., B.S., Adel., 1923, F.R.C.S. Edin.,1928 (also known as Dr Roy Angus) was born in Murrumbeena, Victoria in 1901 and lived until 1970. He qualified as a doctor in 1923 at University of Adelaide, was Resident Medical Officer at the Royal Adelaide Hospital in 1924 and for a period was house surgeon to Sir (then Mr.) Henry Simpson Newland. Dr Angus was briefly an Assistant to Dr Riddell of Kapunda, then commenced private practice at Curramulka, Yorke Peninsula, SA, where he was physician, surgeon and chemist. In 1926, he was appointed as new Medical Assistant to Dr Thomas Francis Ryan (T.F. Ryan, or Tom), in Nhill, Victoria, where his experiences included radiology and pharmacy. In 1927 he was Acting House Surgeon in Dr Tom Ryan’s absence. Dr Angus had become engaged to Gladys Forsyth and they decided he would take time to further his studies overseas in the UK in 1927. He studied at London University College Hospital and at Edinburgh Royal Infirmary and in 1928, was awarded FRCS (Fellow from the Royal College of Surgeons), Edinburgh. He worked his passage back to Australia as a Ship’s Surgeon on the on the Australian Commonwealth Line’s T.S.S. Largs Bay. Dr Angus married Gladys in 1929, in Ballarat. (They went on to have one son (Graham 1932, born in SA) and two daughters (Helen (died 12/07/1996) and Berenice (Berry), both born at Mira, Nhill ) Dr Angus was a ‘flying doctor’ for the A.I.M. (Australian Inland Ministry) Aerial Medical Service in 1928 . The organisation began in South Australia through the Presbyterian Church in that year, with its first station being in the remote town of Oodnadatta, where Dr Angus was stationed. He was locum tenens there on North-South Railway at 21 Mile Camp. He took up this ‘flying doctor’ position in response to a call from Dr John Flynn; the organisation was later known as the Flying Doctor Service, then the Royal Flying Doctor Service. A lot of his work during this time involved dental surgery also. Between 1928-1932 he was surgeon at the Curramulka Hospital, Yorke Peninsula, South Australia. In 1933 Dr Angus returned to Nhill where he’d previously worked as Medical Assistant and purchased a share of the Nelson Street practice and Mira hospital from Dr Les Middleton one of the Middleton Brothers, the current owners of what was once Dr Tom Ryan’s practice. Dr L Middleton was House Surgeon to the Nhill Hospital 1926-1933, when he resigned. [Dr Tom Ryan’s practice had originally belonged to his older brother Dr Edward Ryan, who came to Nhill in 1885. Dr Edward saw patients at his rooms, firstly in Victoria Street and in 1886 in Nelson Street, until 1901. The Nelson Street practice also had a 2 bed ward, called Mira Private Hospital ). Dr Edward Ryan was House Surgeon at the Nhill Hospital 1884-1902 . He also had occasions where he successfully performed veterinary surgery for the local farmers too. Dr Tom Ryan then purchased the practice from his brother in 1901. Both Dr Edward and Dr Tom Ryan work as surgeons included eye surgery. Dr Tom Ryan performed many of his operations in the Mira private hospital on his premises. He too was House Surgeon at the Nhill Hospital 1902-1926. Dr Tom Ryan had one of the only two pieces of radiology equipment in Victoria during his practicing years – The Royal Melbourne Hospital had the other one. Over the years Dr Tom Ryan gradually set up what was effectively a training school for country general-practitioner-surgeons. Each patient was carefully examined, including using the X-ray machine, and any surgery was discussed and planned with Dr Ryan’s assistants several days in advance. Dr Angus gained experience in using the X-ray machine there during his time as assistant to Dr Ryan. Dr Tom Ryan moved from Nhill in 1926. He became a Fellow of the Royal Australasian College of Surgeons in 1927, soon after its formation, a rare accolade for a doctor outside any of the major cities. He remained a bachelor and died suddenly on 7th Dec 1955, aged 91, at his home in Ararat. Scholarships and prizes are still awarded to medical students in the honour of Dr T.F. Ryan and his father, Dr Michael Ryan, and brother, John Patrick Ryan. ] When Dr Angus bought into the Nelson Street premises in Nhill he was also appointed as the Nhill Hospital’s Honorary House Surgeon 1933-1938. His practitioner’s plate from his Nhill surgery states “HOURS Daily, except Tuesdays, Fridays and Saturday afternoons, 9-10am, 2-4pm, 7-8pm. Sundays by appointment”. This plate is now mounted on the doorway to the Port Medical Office at Flagstaff Hill Maritime Village, Warrnambool. Dr Edward Ryan and Dr Tom Ryan had an extensive collection of historical medical equipment and materials spanning 1884-1926 and when Dr Angus took up practice in their old premises he obtained this collection, a large part of which is now on display at the Port Medical Office at Flagstaff Hill Maritime Village in Warrnambool. During his time in Nhill Dr Angus was involved in the merging of the Mira Hospital and Nhill Public Hospital into one public hospital and the property titles passed on to Nhill Hospital in 1939. In 1939 Dr Angus and his family moved to Warrnambool where he purchased “Birchwood,” the 1852 home and medical practice of Dr John Hunter Henderson, at 214 Koroit Street. (This property was sold in1965 to the State Government and is now the site of the Warrnambool Police Station. ). The Angus family was able to afford gardeners, cooks and maids; their home was a popular place for visiting dignitaries to stay whilst visiting Warrnambool. Dr Angus had his own silk worm farm at home in a Mulberry tree. His young daughter used his centrifuge for spinning the silk. Dr Angus was appointed on a part-time basis as Port Medical Officer (Health Officer) in Warrnambool and held this position until the 1940’s when the government no longer required the service of a Port Medical Officer in Warrnambool; he was thus Warrnambool’s last serving Port Medical Officer. (The duties of a Port Medical Officer were outlined by the Colonial Secretary on 21st June, 1839 under the terms of the Quarantine Act. Masters of immigrant ships arriving in port reported incidents of diseases, illness and death and the Port Medical Officer made a decision on whether the ship required Quarantine and for how long, in this way preventing contagious illness from spreading from new immigrants to the residents already in the colony.) Dr Angus was a member of the Australian Medical Association, for 35 years and surgeon at the Warrnambool Base Hospital 1939-1942, He served as a Surgeon Captain during WWII1942-45, in Ballarat, Victoria, and in Bonegilla, N.S.W., completing his service just before the end of the war due to suffering from a heart attack. During his convalescence he carved an intricate and ‘most artistic’ chess set from the material that dentures were made from. He then studied ophthalmology at the Royal Melbourne Eye and Ear Hospital and created cosmetically superior artificial eyes by pioneering using the intrascleral cartilage. Angus received accolades from the Ophthalmological Society of Australasia for this work. He returned to Warrnambool to commence practice as an ophthalmologist, pioneering in artificial eye improvements. He was Honorary Consultant Ophthalmologist to Warrnambool Base Hospital for 31 years. He made monthly visits to Portland as a visiting surgeon, to perform eye surgery. He represented the Victorian South-West subdivision of the Australian Medical Association as its secretary between 1949 and 1956 and as chairman from 1956 to 1958. In 1968 Dr Angus was elected member of Spain’s Barraquer Institute of Barcelona after his research work in Intrasclearal cartilage grafting, becoming one of the few Australian ophthalmologists to receive this honour, and in the following year presented his final paper on Living Intrasclearal Cartilage Implants at the Inaugural Meeting of the Australian College of Ophthalmologists in Melbourne In his personal life Dr Angus was a Presbyterian and treated Sunday as a Sabbath, a day of rest. He would visit 3 or 4 country patients on a Sunday, taking his children along ‘for the ride’ and to visit with him. Sunday evenings he would play the pianola and sing Scottish songs to his family. One of Dr Angus’ patients was Margaret MacKenzie, author of a book on local shipwrecks that she’d seen as an eye witness from the late 1880’s in Peterborough, Victoria. In the early 1950’s Dr Angus, painted a picture of a shipwreck for the cover jacket of Margaret’s book, Shipwrecks and More Shipwrecks. She was blind in later life and her daughter wrote the actual book for her. Dr Angus and his wife Gladys were very involved in Warrnambool’s society with a strong interest in civic affairs. Their interests included organisations such as Red Cross, Rostrum, Warrnambool and District Historical Society (founding members), Wine and Food Society, Steering Committee for Tertiary Education in Warrnambool, Local National Trust, Good Neighbour Council, Housing Commission Advisory Board, United Services Institute, Legion of Ex-Servicemen, Olympic Pool Committee, Food for Britain Organisation, Warrnambool Hospital, Anti-Cancer Council, Boys’ Club, Charitable Council, National Fitness Council and Air Raid Precautions Group. He was also a member of the Steam Preservation Society and derived much pleasure from a steam traction engine on his farm. He had an interest in people and the community He and his wife Gladys were both involved in the creation of Flagstaff Hill, including the layout of the gardens. After his death (28th March 1970) his family requested his practitioner’s plate, medical instruments and some personal belongings be displayed in the Port Medical Office surgery at Flagstaff Hill Maritime Village, and be called the “W. R. Angus Collection”. The W.R. Angus Collection is significant for still being located at the site it is connected with, Doctor Angus being the last Port Medical Officer in Warrnambool. The collection of medical instruments and other equipment is culturally significant, being an historical example of medicine from late 19th to mid-20th century.

Nitrous oxide has been used for anaesthesia in dentistry since December 1844, where Horace Wells made the first 12–15 dental operations with the gas in Hartford. Its debut as a generally accepted method, however, came in 1863, when Gardner Quincy Colton introduced it more broadly at all the Colton Dental Association clinics, that he founded in New Haven and New York City. Hospitals administer nitrous oxide as one of the anaesthetic drugs delivered by anaesthetic machines. Nitrous oxide is a weak general anaesthetic, and so is generally not used alone in general anaesthesia. In general anaesthesia it is used as a carrier gas with oxygen for more powerful general anaesthetic drugs.Medium size empty blue coloured cylinder with rounded base and painted white neck once containing Nitrous Oxide.
