Operating Rooms
An operating theater (also known as an Operating Room (OR), operating suite, operation suite, or Operation Theatre (OT)) is a facility within a hospital where Surgery, surgical operations are carried out in an asepsis, aseptic environment. Historically, the term "operating theater" referred to a non-sterile, tiered theater (building), 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. Classification of operation theatre Operating rooms are spacious, in a cleanroom, and well-lit, typically with overhead Surgical lighting, surgical lights, and may have viewing screens and Medical monitor, 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.

Cardiac Catheterization
Cardiac catheterization (heart cath) is the insertion of a catheter into a heart chamber, chamber or Blood vessel, 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, Balloon catheter, 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 techni ...

Mercury(II) Chloride
Mercury(II) chloride (mercury bichloride, mercury dichloride, mercuric chloride), historically also sulema or corrosive sublimate, is the inorganic chemical compound of mercury and chlorine with the formula HgCl2, used as a laboratory reagent. It is a white crystalline solid and a molecular compound that is very toxic to humans. Once used as a first line treatment for syphilis, it has been replaced by the more effective and less toxic procaine penicillin since at least 1948. 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. Properties Mercuric chloride is not a salt composed of discrete ions, but it is ... [...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 30–60 minutes at a gauge pressure of 103 kPa 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 autoclaves are widely us ...

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, an operating 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 ...

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 Kiel ( ; ) is the capital and most populous city in the northern Germany, German state of Schleswig-Holstein. With a population of around 250,000, it is Germany's largest city on the Baltic Sea. It is located on the Kieler Förde inlet of the Ba .... 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Padua

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 or viruses) present in fluid or on a specific surface or object. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure food preservation, 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, fluid or 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 of time slowed the decay of foods and various liquids, preserving them for safe consumption for a longer t ...

Apron
An apron is a garment worn over other clothing to cover the front of the body to protect from liquids. They have several purposes, most commonly 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. The word comes from Old French ''napron'', meaning a small piece of cloth. Over time "a napron" became "an apron" through a linguistic process called rebracketing. Styles There are many different apron forms depending on the purpose of the apron. A basic distinction is between waist aprons, which cover the body f ...
