Operating Theatre
An operating theater (also known as an operating room (OR), operating suite, or operation suite) is a facility within a hospital where surgical operations are carried out in an aseptic environment. Historically, the term "operating theater" referred to a non-sterile, tiered theater or amphitheater in which students and other spectators could watch surgeons perform surgery. Contemporary operating rooms are usually devoid of a theater setting, making the term "operating theater" a misnomer in those cases. Operating rooms Operating rooms are spacious, in a cleanroom, and well-lit, typically with overhead surgical lights, and may have viewing screens and monitors. Operating rooms are generally windowless, though windows are becoming more prevalent in newly built theaters to provide clinical teams with natural light, and feature controlled temperature and humidity. Special air handlers filter the air and maintain a slightly elevated pressure. Electricity support has backup systems in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cardiac Catheterization
Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart. This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks"). Catheterization is most often performed in special laboratories with fluoroscopy and highly maneuverable tables. These "cath labs" are often equipped with cabinets of catheters, stents, balloons, etc. of various sizes to increase efficiency. Monitors show the fluoroscopy imaging, electrocardiogram (ECG), pressure waves, and more. Uses Coronary angiography is a diagnostic procedure that allows visualization of the coronary vessels. Fluoroscopy is used to visualize the lumens of the arteries as a 2-D projection. Should these arteries show narrowing or blockage, then techniques exist to open these arteries. Percutane ...

Mercury(II) Chloride
Mercury(II) chloride (or mercury bichloride, mercury dichloride), historically also known as sulema or corrosive sublimate, is the inorganic chemical compound of mercury and chlorine with the formula HgCl2. It is white crystalline solid and is a laboratory reagent and a molecular compound that is very toxic to humans. Once used as a treatment for syphilis, it is no longer used for medicinal purposes because of mercury toxicity and the availability of superior treatments. Synthesis Mercuric chloride is obtained by the action of chlorine on mercury or on mercury(I) chloride. It can also be produced by the addition of hydrochloric acid to a hot, concentrated solution of mercury(I) compounds such as the nitrate: :Hg2(NO3)2 + 4 HCl → 2 HgCl2 + 2 H2O + 2 NO2 Heating a mixture of solid mercury(II) sulfate and sodium chloride also affords volatile HgCl2, which can be separated by sublimation. Process for synthesis of Mercuric chloride first appeared in Abu Bakr al-Razi's ''De ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autoclave
An autoclave is a machine used to carry out industrial and scientific processes requiring elevated temperature and pressure in relation to ambient pressure and/or temperature. Autoclaves are used before surgical procedures to perform sterilization and in the chemical industry to cure coatings and vulcanize rubber and for hydrothermal synthesis. Industrial autoclaves are used in industrial applications, especially in the manufacturing of composites. Many autoclaves are used to sterilize equipment and supplies by subjecting them to pressurized saturated steam at for around 30-60 minutes at a pressure of 15 psi (103 kPa or 1.02 atm) depending on the size of the load and the contents. The autoclave was invented by Charles Chamberland in 1879, although a precursor known as the steam digester was created by Denis Papin in 1679. The name comes from Greek ''auto-'', ultimately meaning self, and Latin ''clavis'' meaning key, thus a self-locking device. Uses Sterilization autoclav ...

Asepsis
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. 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. History The modern concept of asepsis evol ...

Gustav Adolf Neuber
Gustav Adolf Neuber (24 June 1850 – 13 April 1932) was a German surgeon born in Tondern (today- Tønder. He studied medicine in several universities, receiving his doctorate in 1875 at the University of Giessen. Later he worked as an assistant to Friedrich von Esmarch (1823-1908) at the University Surgical Clinic in Kiel. In 1884 he first proposed the use of separate operating rooms for septic and non-septic surgery, emphasizing the need for complete cleanliness in all aspects of surgery. 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. In 1879 he developed a "decalcified bone tube" for wound drainage. In the field of plastic surgery Plastic surgery is a surgical specialty involving the restoration, reconstruction or alteration of the human body. It can be divided into two main categories: reconstructive surgery and cosm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Padua
The University of Padua ( it, Università degli Studi di Padova, UNIPD) is an Italian university located in the city of Padua, region of Veneto, northern Italy. The University of Padua was founded in 1222 by a group of students and teachers from Bologna. Padua is the second-oldest university in Italy and the world's fifth-oldest surviving university.

Sterilization (microbiology)
Sterilization refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents such as prions present in or on a specific surface, object, or fluid. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic. Applications Foods One of the first steps toward modernized sterilization was made by Nicolas Appert, who discovered that application of heat over a suitable period slowed the decay of foods and various liquids, preserving them for safe consumption for a longer time than was typical. Canning of foods is an extension of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apron
An apron is a garment that is worn over other clothing to cover the front of the body. The word comes from old French ''napron'' meaning a small piece of cloth, however over time "a napron" became "an apron", through a linguistics process called rebracketing. It may have several purposes, typically as a functional accessory that protects clothes and skin from stains and marks. However, other types of aprons may be worn as a decoration, for hygienic reasons, as part of a uniform, or as protection from certain dangers such as acid, allergens or excessive heat. It can also be used at work stations to hold extra tools and pieces or protect from dust and unwanted materials. As a top layer that covers the front body, the apron is also worn as a uniform, adornment, ceremonial garb (e.g. Masonic apron) or fashion statement. Apron styles can be practical, fashionable, and sentimental. Apron styles There are many different apron forms depending on the purpose of the apron. A basic di ...
