Asepsis refers to any procedure that is performed under sterile conditions. This includes medical and laboratory techniques (such as with bacterial cultures). There are two types of asepsis - medical and surgical. Medical or clean asepsis reduces the number of organisms and prevents their spread; surgical or sterile asepsis includes procedures to eliminate micro-organisms from an area and is practiced by surgical technologists and nurses.

Hand scrubbing procedure for surgery Asepsis is the state of being free from disease-causing micro-organisms (such as pathogenic bacteria, viruses, pathogenic fungi, and parasites). There are two categories of asepsis: medical and surgical. The modern day notion of asepsis is derived from the older antiseptic techniques, a shift initiated by different individuals in the 19th century who introduced practices such as the sterilizing of surgical tools and the wearing of surgical gloves during operations. The goal of asepsis is to eliminate infection, not to achieve sterility.

At the end of the 19th century, Joseph Lister and his followers expanded the term "antisepsis" and coined "asepsis," with the justification that Lister had initially "suggested excluding septic agents from the wound from the start." Generally, however, asepsis is seen as a continuation of antisepsis since many of the values are the same, such as a "germ-free environment around the wound or patient," and techniques pioneered under both names are used in conjunction today.

The surface can be modified in many ways, including plasma modification and applying coatings to the substrate. Surface modifications can be used to affect surface energy, adhesion, biocompatibility, chemical inertness, lubricity, sterility, asepsis, thrombogenicity, susceptibility to corrosion, degradation, and hydrophilicity.

His efforts in 1913 began to be used in gynecology radium. The founder of a new direction in operative gynecology. He played for laparotomy vaginal way, actively introduced asepsis. Developed methods of surgical treatment of prolapse and loss of sexual organs.

Barber-surgeons generally had a bad reputation that was not to improve until the development of academic surgery as a specialty of medicine, rather than an accessory field. Basic surgical principles for asepsis etc., are known as Halsteads principles. There were some important advances to the art of surgery during this period.

Neonates weighing more than 1800 grams or having gestational maturity of 34 weeks or more are categorized under level I care. The care consists of basic care at birth, provision of warmth, maintaining asepsis and promotion of breastfeeding. This type of care can be given at home, subcenter and primary health centre.

The initial puncture is with a sharp instrument, and this may lead to hemorrhage or perforation of the organ in question. Infection is a possible complication, and hence asepsis is practiced during most Seldinger procedures. Loss of the guidewire into the cavity or blood vessel is a significant and generally preventable complication.

The circulating nurse is a perioperative nurse who assists in managing the nursing care of a patient during surgery. The circulating nurse observes for breaches in surgical asepsis and coordinates the needs of the surgical team. The circulating nurse is not scrubbed in the case but rather manages the care and environment during surgery.

In the pre- asepsis era, surgeon Frederick Treves (1853–1923) wrote, "Practically all major wounds suppurated. Pus was the most common subject of converse [among surgeons], because it was the most prominent feature in the surgeon's work. It was classified according to degrees of vileness." But pus of the right kind was considered desirable.

Wellcome V0026152 13-14 CHARLOTTE SQUARE The grave of Prof Francis Mitchell Caird, Dean Cemetery, Edinburgh Francis Mitchell Caird FRCSEd (8 August 1853–2 November1926) was a Scottish surgeon who was an early advocate of Listerian antisepsis and then asepsis. He was a pioneer of gastrointestinal surgery.

In the 19th century, asepsis improved surgical hygiene and as the survival statistics went up, surgical removal of the tumor became the primary treatment for cancer. With the exception of William Coley who in the late 19th century felt that the rate of cure after surgery had been higher before asepsis (and who injected bacteria into tumors with mixed results), cancer treatment became dependent on the individual art of the surgeon at removing a tumor. The underlying cause of his results might be that infection stimulates the immune system to destroy left tumor cells. During the same period, the idea that the body was made up of various tissues, that in turn were made up of millions of cells, laid rest the humor-theories about chemical imbalances in the body.

In 1886, he opened his own private hospital on Königsweg in Kiel, where he implemented modern principles of asepsis. Neuber's clinic in Kiel is considered to be the first aseptic hospital in the world.Wir Kieler (biography) In 1879 he developed a "decalcified bone tube" for wound drainage. In the field of plastic surgery, he introduced a procedure for "fat auto-grafting".

The line between antisepsis and asepsis is interpreted differently, depending on context and time. In the past, antiseptic operations occurred in people's homes or in operating theaters before a large crowd. Procedures for implementing antisepsis varied among physicians and experienced constant changes. Until the late 19th century, physicians rejected the connection between Louis Pasteur's germ theory that bacteria caused diseases and antiseptic techniques.

But his chief service was rather more general, and hard to describe. It was to bring in a new and better way of regarding the patient. Antisepsis and asepsis, coming in when he was young, had turned the attention of surgeons to external and often extraneous things. Fighting germs, they tended to forget the concrete sick man on the table.

Carl Waldemar Walter (1905 - May 5, 1992) was a surgeon, inventor, and professor at Harvard Medical School. Walter has been called "a pioneer in the transfusion and storage of blood," credited with founding one of the world's first blood banks and invention of the first blood collection bag. He was also known for his prolific work in the advocacy, application, and study of asepsis.

Ideally, a surgical field is sterile, meaning it is free of all biological contaminants (e.g. fungi, bacteria, viruses), not just those that can cause disease, putrefaction, or fermentation. Even in an aseptic state, a condition of sterile inflammation may develop. The term often refers to those practices used to promote or induce asepsis in an operative field of surgery or medicine to prevent infection.

Accessed July 17, 2007. For simple castration of normal animals, the advantages to recumbent castration are that the horse is prone, better asepsis (sterile environment) can be maintained, and better haemostasis (control of bleeding) is possible. In addition, there is significantly less risk of the surgeon or assistants being kicked. In a more complex situation such as castration of cryptorchid animals, the inguinal canal is more easily accessed.

Lawson Tait, born Robert Lawson Tait (1 May 1845 – 13 June 1899) was a pioneer in pelvic and abdominal surgery and developed new techniques and procedures. He emphasized asepsis and introduced and advocated for surgical techniques that significantly reduced mortality. He is well known for introducing salpingectomy in 1883 as the treatment for ectopic pregnancy, a procedure that has saved countless lives since then. Tait and J. Marion Sims are considered the fathers of gynecology.

Among his greatest influences was James Syme, the University's Chair of Clinical Surgery. Tait considered Syme to be a remarkable surgeon who emphasized care and cleanliness, and he particularly admired Syme's taste for controversy. One of Syme's closest students was Joseph Lister, with whom Tait would later have significant disputes with over the rivaling practices of Antisepsis and Asepsis. Tait graduated and received his Licentiate of the Royal College of Physicians in 1866.

He studied medicine in Paris, where he received his doctorate in 1885. In 1888 he became a hospital surgeon, subsequently performing surgery at the Hôpitaux Broussais, Boucicaut, and Lariboisièr during his career.Henri Victor Chaput at Who Named It He was at the forefront of surgical asepsis, advocating the use of sterile rubber (caoutchouc) gloves during operations. He was known for his preference of lumbar anaesthetics (using stovaine) instead of general anaesthesia for most surgical operations.

Instruments were also washed in the same solution and assistants sprayed the solution in the operating theatre. One of his additional suggestions was to stop using porous natural materials in manufacturing the handles of medical instruments. Lister left Glasgow University in 1869 and was succeeded by George Husband Baird MacLeod. Lister then returned to Edinburgh as successor to Syme as Professor of Surgery at the University of Edinburgh and continued to develop improved methods of antisepsis and asepsis.

The modern concept of asepsis evolved in the 19th century through multiple individuals. Ignaz Semmelweis showed that hand washing prior to delivery reduced puerperal fever. Despite this, many hospitals continued to practice surgery in unsanitary conditions, with some surgeons taking pride in their bloodstained operating gowns. It was not until after reading of the findings by Louis Pasteur that Joseph Lister introduced the use of carbolic acid as an antiseptic, and in doing so, reduced surgical infection rates.

Two major advances occurred in the late 19th century, which together allowed the transition to modern surgery. An appreciation of the germ theory of disease led rapidly to the development and application of antiseptic techniques in surgery. Antisepsis, which soon gave way to asepsis, reduced the overall morbidity and mortality of surgery to a far more acceptable rate than in previous eras. Concurrent with these developments were the significant advances in pharmacology and physiology which led to the development of general anesthesia and the control of pain.

As a young man he worked as an assistant at Adolf Aron Baginsky's Kaiser-und-Kaiserin-Kinderkrankenhaus in Berlin.Deutsche Biographie (biography) In 1897 at Dresden, he founded a private Säuglingsheim (home for babies), a hospital devoted entirely for in- patient treatment of sick infants. This institution was considered to be the first of its kind anywhere. Here, Schlossmann worked at improving care for infants, that included an environment adhering to strict asepsis, systematic training of pediatric nurses and testing that involved his personal ideas on natural diet.

Caroline Hampton became the chief nurse of the operating room when Johns Hopkins Hospital opened in 1889. When "[i]n the winter of 1889 or 1890" she developed a skin reaction to mercuric chloride that was used for asepsis, William Halsted, soon-to-be her husband, asked the Goodyear Rubber Company to produce thin rubber gloves for her protection. In 1894 Halsted implemented the use of sterilized medical gloves at Johns Hopkins. The first disposable latex medical gloves were manufactured in 1964 by Ansell.

Cheatle was deeply influenced by Lord Lister, and this showed up not only in his interest in research and close attention to detail, but also in his dress and physical mannerisms. However, although at first a strong supporter of Lister's antiseptic approach, he later was the first surgeon to use asepsis at King's. In 1920 Cheatle was the first to repair an inguinofemoral hernia from above the pubis using the posterior preperitoneal space. The innovation received little attention at the time, and was not mentioned in his obituary.

These three crucial advances - the adoption of a scientific methodology toward surgical operations, the use of anaesthetic and the introduction of sterilised equipment - laid the groundwork for the modern invasive surgical techniques of today. In the late 19th century William Stewart Halstead (1852–1922) laid out basic surgical principles for asepsis known as Halsteads principles. Halsted also introduced the latex medical glove. After one of his nurses suffered skin damage due to having to sterilize her hands with carbolic acid, Halsted had a rubber glove that could be dipped in carbolic acid designed.

He invented the "basted suture," which he used to treat aneurysms. He also was among the first to practice phlebotomy, suturing the tear in a vein. He developed an intestinal suture that could be naturally expelled from the channel through which it was placed, which did not necessitate the laparotomic incision that was previously required for suture removal. Some of his innovations were in the field of general medicine: he was an early practitioner of asepsis, taking exceptional care to clean his hands, instruments, and the operating room.

He was relieved from the faculty in 1954. Professor Miljanić was the author of the first textbooks of anatomy in Serbian, a monograph on asepsis, as well as a lot of scientific articles on anatomy and surgery in different journals in Yugoslavia and abroad. As a French ex-pupil he was elected president of the French ex-pupils Association and the founder of the bilingual Serbian-French journal Anali medicine i hirurgije (Annals of Medicine and Surgery), published 1927-1934. In 1930, he unveiled the Monument of Gratitude to France in Belgrade's Kalemegdan Park, together with King Alexander I of Yugoslavia.

Antisepsis, which soon gave way to asepsis, reduced the overall morbidity and mortality of surgery to a far more acceptable rate than in previous eras. Concurrent with these developments were the significant advances in pharmacology and physiology which led to the development of general anaesthesia and the control of pain. On 14 November 1804, Hanaoka Seishū, a Japanese doctor, became the first person to successfully perform surgery using general anaesthesia. In the 20th century, the safety and efficacy of general anaesthesia was improved by the routine use of tracheal intubation and other advanced airway management techniques.

Assaky's contributions were primarily in the fields of anatomy, physiology, embryology, surgery and gynecology, and his work was cited in numerous treatises of medicine and surgery. He was among the first Romanian surgeons to introduce modern principles of asepsis, antisepsis and a properly equipped operating room, as well as techniques of general surgery. His chief work, the doctoral thesis, received a prize from the Académie Nationale de Médecine; it reveals his method as being a precursor of nerve surgery and of experimental techniques in the field. Also in 1886, he published research into the influence of mechanical conditions on nerve growth.

Lawson Tait shifted the movement then from antisepsis to asepsis, instilling practices such as a strict no-talking policy within his operating room and drastically limiting the number of people to come in contact with a patient's wound. Ernst von Bergmann also introduced the autoclave, a device used for the practice of the sterilization of surgical instruments. Image of William Stewart Halsted But, everything from operating room uniforms to gloves was pioneered by William Halsted. Preceding modern-day scrubs attire, Halsted implemented a no street clothes policy in his operating room, opting to wear a completely white, sterile uniform consisting of a duck suit, tennis shoes, and skullcap.

In 1845 he proceeded M.D. at London and joined his father as lecturer on midwifery in the Bristol medical school; he was sole lecturer from 1850 until 1895, when he was appointed emeritus professor. In 1853 he was elected physician accoucheur to the Bristol General Hospital, one of the first appointments of the kind out of London; he held this post until 1875, when he became consulting obstetric physician. As a reputed consultant, Swayne had a large practice in the west of England. He was ahead of his time in stressing asepsis, and deprecated long hair or beards for those involved surgery or midwifery.

Admired for its uncompromising realism, The Gross Clinic has an important place documenting the history of medicine—both because it honors the emergence of surgery as a healing profession (in previous years surgery was associated primarily with Amputation, which caused severe medical complications, later killing the person) , and because it shows what an surgical theater looked like in the nineteenth century. The painting is based on a surgery witnessed by Eakins, in which Gross treated a young man for osteomyelitis of the femur. Gross is pictured here performing a conservative operation, as opposed to the amputation normally carried out. Here, surgeons crowd around the anesthetized patient in their frock coats—this is just prior to the adoption of a hygienic surgical environment (see asepsis).

In his book Fifty Years; A Surgeon"Fifty Years; A Surgeon, by Robert T. Morris" he gives a clear and complete description of hospital conditions at that time before the entrance of antisepsis in the world of surgery as a normal and necessary routine. So then at some point the Bellevue had to make some changes, due to the fact that Lister theories about the antisepsis had been accepted in the world of medicine. In the Surgical Division an extremely rapid change in method took place, so that the antiseptic surgery had changed the whole appearance of wards in the hospital. Morris was one of the main supporter of the new method enounced by Lister, and later on, of the new theories about asepsis, introduced by Dr. Ernst von Bergmann in 1892.

The most common organic postpartum psychosis is infective delirium. This was mentioned by Hippocrates Hippocrates (5th Century BC) Epidemics, book III, volume 1, pages 280-283, in the edition translated by W H S Jones, 1931. : there are 8 cases of puerperal or post-abortion sepsis among the 17 women in the 1st and 3rd books of epidemics, all complicated by delirium. In Europe and North America the foundation of the metropolitan maternity hospitals, together with instrumental deliveries and the practice of attending necropsies, led to epidemics of streptococcal puerperal fever, resulting in maternal mortality rates up to 10%. The peak was about 1870, after which antisepsis and asepsis gradually brought them under control. These severe infections were often complicated by delirium, but it was not until the nosological advances of Chaslin Chaslin P (1895) Confusion Mentale Primitive, Stupidité, Démence aiguë, Stupeur Primitive.

Stephen Barrett, "Stay away from 'holistic' and 'biological' dentists", Quackwatch, accessed online: 17 Sep 2013. Conventional belief is that microorganisms within inaccessible regions of a tooth's roots are rendered harmless once entrapped by the filling material, although little evidence supports this. A H Rogers in 1976 and E H Ehrmann in 1977 had dismissed any relation between endodontics and focal infection. At dentist George Meinig's 1994 book, Root Canal Cover-Up Exposed, discussing researches of Rosenow and of Price, some dentistry scholars reasserted that the claims were evaluated and disproved by the 1940s.J Craig Baumgartner, Leif K Bakland & Eugene I Sugita, ch 3 "Microbiology of endodontics and asepsis in endodontic practice" , in John Ide Ingle & Leif K Bakland, eds, Endodontics, 5th edn (Hamilton Ontario: BC Decker, 2002), p 64. Yet Meinig was but one of at least three authors who in the early 1990s independently renewed the concern.
