![]() ![]() In medicine, sterilization techniques and methods are used whenever a procedure requires the loss of the integrity of the skin, forming a gateway for microorganisms to enter the body. The principles of asepsis are more commonly used in operating rooms, delivery rooms or when performing a procedure in the hospital bed that requires the greatest sterility possible, such as the placement of a chest tube, the taking of a central line, placement of a urethral catheter, among others. In 1867, Joseph Lister published a paper in which he proposed to clean the wounds with carbolic acid. Pasteur also discovered that the heat killed these microorganisms, and that it was only necessary to prevent new microorganisms from entering after eliminating them to avoid putrefaction. In 1857, Pasteur He showed when studying the fermentation, that the presence of bacteria and microorganisms, and their reproduction in number, produced putrefaction. Subsequently, Phillipe Ignace Semmelweis, noted that the rate of death from puerperal fever was directly proportional to the number of interventions where the doctor did not wash their hands previously and ordered the installation of sinks at the entrances to the operating rooms for all medical personnel. ![]() Joseph Clarke in 1790, discovered the relationship of puerperal deaths with the poor hygiene of the precincts destined for motherhood, thus ordering the exhaustive cleaning of those enclosures. The pattern of communication between the interior and exterior of the human body began to be felt, with the onset of fevers that normally culminated in the death of the patient. How did the asepsis come about?įrom the seventeenth to the nineteenth century, deaths due to systemic infections after injuries, surgical interventions or in the immediate postpartum period were very numerous. ![]() It provides all health care users with all the necessary objects and materials, in optimal conditions for their use. The main objective of asepsis is to reduce the risk of disease transmission in hospital centers, especially in the surgical area. The term asepsis should not be confused with the term antisepsis, which although they go hand in hand, the latter refers to the disinfection process of an organism previously infected with living pathogenic microorganisms. ![]()
