A widely used antiseptic (see ANTISEPTICS) which is active against a range of microorganisms, including gram-positive and gram-negative organisms (see GRAM’S STAIN), Shigella dysenteriae, and Salmonella typhi. One of its advantages is that it retains its activity in the presence of soap, and is therefore often used in soaps and creams in a concentration of 1–2 per cent. It must be used with caution in babies as it can be absorbed through the skin and prove harmful. Hexachlorophene must not be used on burned or excoriated skin.
Creation of a germfree environment to protect a patient from infection. Aseptic technique is used during surgery and when caring for people suffering from diseases, such as leukaemia, in which the immune system is suppressed. All people who come in contact with the patient must scrub their hands and wear pre-sterilized gowns and disposable gloves and masks. Surgical instruments are sterilized in an autoclave. The patient’s skin is cleaned with antiseptic solutions of iodine or hexachlorophene. A special ventilation system in the operating theatre purifies the air.
