Asepsis is the state of being free from disease-causing micro-organisms (such as pathogenic bacteria, viruses, pathogenic fungi, and parasites). [1] There are two categories of asepsis: medical and surgical. [ 1 ]
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
Several medical conditions increase a person's susceptibility to infection and developing sepsis. Common sepsis risk factors include age (especially the very young and old); conditions that weaken the immune system such as cancer , diabetes , or the absence of a spleen ; and major trauma and burns .
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 designed a rubber glove that could be ...
Aseptic processing was derived from Olin Ball's heat-cool-fill (HCF) machine that was developed in 1927. [5] While HCF was successful in improving the sensory quality of the processed chocolate milk as compared to canned product, the use of the equipment was hindered by its cost, maintenance, and inflexibility to process various container sizes, rendering the machine a failure.
A medical professional inserts a needle between two vertebrae to remove cerebrospinal fluid (CSF) from the spinal cord. [6] The cerebrospinal fluid collected from the lumbar puncture is analyzed by microscope examination or by culture to distinguish between bacterial and aseptic meningitis.
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. [1] An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection.
Halsted's principles, also known as Tenets of Halsted, are the basic principles of surgical technique regarding tissue handling. [1] These key points were introduced in the late 19th century by William Stewart Halsted, co-founder of Johns Hopkins Hospital.
