The goal of asepsis is to eliminate infection, not to achieve sterility. [1] 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. [1] Even in an aseptic state, a condition of sterile inflammation may develop.
In 1867 Joseph Lister is considered to be the father of antiseptic surgery. By sterilizing the instruments with diluted carbolic acid and using it to clean wounds, post-operative infections were reduced, making surgery safer for patients. [6] In the years between 1876 and 1884 Robert Koch provided much insight into infectious diseases.
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) 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.

Infection after surgery is relatively uncommon, but occurs as much as 33% in specific types of surgeries. Infections of surgical sites range from 1% to 33%. MRSA sepsis that occurs within 30 days following a surgical infection has a 15–38% mortality rate; MRSA sepsis that occurs within one year has a mortality rate of around 55%.
Surgery [a] is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissues (body fat, glands, scars ...
Debridement is the medical removal of dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue. [2] [3] Removal may be surgical, mechanical, chemical, autolytic (self-digestion), or by maggot therapy.
Schwartz's Principles of Surgery is a seminal textbook of surgery originally written by Seymour Schwartz, MD. The first edition was published in 1969 by the McGraw-Hill . Latest edition has published in 2019 as the 11th edition in textbook's 50th anniversary. [ 1 ]
A New England Compounding Center meningitis outbreak that began in September 2012 sickened 798 individuals and resulted in the deaths of 64 people. [2] [3] [4] In September 2012, the Centers for Disease Control and Prevention, in collaboration with state and local health departments and the Food and Drug Administration (FDA), began investigating a multistate outbreak of fungal meningitis and ...
