Infection Prevention Module Introduction Infection control Antiseptic techniques Operating Theater Aseptic techniques
Introduction Description Objectives
Description • Infection Prevention in Surgical Setting is one of important preventive methods in order to achieve infection control in clinical and surgical practices.
Objectives • The aims of this method are : • To minimize surgical site infection • To protect health personnel • To improve wound healing • To minimize disability, morbidity, & mortality • To reduce the cost of hospital care
Specific Learning Objectives : • To describe the definition and history of sterilization, disinfection, decontamination, anti and a - septic techniques. • To describe six methods of sterilization. • To describe three categories of surgical instruments • To describe 6 rules of aseptic techniques
Specific Learning Objectives : • To perform aseptic techniques correctly, including (P5): • Applying surgical attire • Hand washing • Surgical scrubbing • Gloving • Surgical Gowning
Definition: • Sterilization : Processes by which all pathogenic & non pathogenic microorganisms, including spores, are killed. • Disinfection: Chemical or physical process of destroying all pathogenic microorganisms, except spore bearing ones; used for inanimate objects, but not on tissues.
Definition: • Decontamination : Process or method by which all contaminated materials that can cause diseases are removed. • Aseptic techniques : Methods by which contamination with microorganisms is prevented. • Antiseptic techniques: Prevention of sepsis by the exclusion, destruction, or inhibition of growth and multiplication of microorganisms from body tissues and fluids.
Historical backgrounds : • Ignas Sammelweis (1818 - 1865) • Puerperal fever increased maternal mortality • Hand scrub with chlorinated-lime solution prior to examination. • Father of nosocomial infection. • Louis Pasteur (1860) • Discover the process of fermentation by microorganisms • Germ theory: against spontaneous generation theory.
Historical backgrounds : • Joseph Lister (1865) • Use carbolic acid solution on surgical dressing in the operating room mortality (Listerization) • Father of modern surgery (Antiseptic technique) • Ernst Von Bergmann (1886) • Introduced “steam sterilizer” • Basic of sterilization aseptic technique • Later: “pressure & vacuum steam sterilizer” was developed
Methods of Infection control • Anti septic techniques • Design and traffic patterns of the operating theatre • Aseptic techniques
Sterilization • The objective of modern surgery • For inanimate objects • Problem : • Some items are not heat resistance
Techniques of Sterilization • Physical: • Heat • Radiation/ ultraviolet ray • Boiling water • Ultrasound • Chemical: • Liquid • Gas
Heat Sterilization • Dry : • Commonly cause damage • For powder, oils, and jelly • Moist : • Steam • High pressure spores • Vacuum constant temperature • Autoclave
Chemical Sterilization • Generally as disinfection • Mechanism of action : • Protein coagulation • Enzyme denaturation in cells • Lysis • Depend on : number of microorganisms, soiling, concentration, and temperature.
Solutions • Jodium and Jodophor • Good bactericide, but irritant • Mixture : povidone-jodine 10% • Alcohol Solution of 70% or 90% • Glutaraldehyde (Formaldehyde Sol. in Alcohol 2%) • Spores are killed within 3 hours
Solutions • Hexachloropene (Halogenated phenol) • Bacterio-static, particularly Gram (+) bacteria • For scrubbing • Chlorhexidine gluconate • Bactericide : Gram (+) & (-). • Good for antiseptic
Gas Sterilization • Formaldehyde • Ethilene-oxide • - propionolactone
Boiling Water • Mild boiling • Vigorous boiling • More active, if 2% sodium-carbonate or 0,1 % sodium-hydroxide being added
The Operating Theater Clean Zone S C R U B S U I T Transitional Zone Sterile core Restricted area Semi – Restricted Area
Traffic patterns of Operating Theatre • The use of aseptic principles requires regulation of traffic and flow patterns of the personnel, patient, equipment, and supplies in operating theatre • Aims : to protect the safety and privacy of patients and the cleanliness and integrity of the environment.
unrestricted area • Elevators • Corridors outside surgical suite
unrestricted area • Entrance • Reception desk • Patient suite
Transitional Zone (Video) • Locker room • Dressing room
Clean Zone (Video) • Surgical suite and corridors • Sterile core
Putting on surgical attire • In the semi & restricted area: • Scrub suit : shirt & trousers • Hair covering: surgical cap/hood • Masks : disposable/ re-useable • Goggle (optional): protective eyewear • Shoe covers are compulsory
Male personnel Female personnel Personnel with veil Surgical attire
Surgical Instruments in the Operating Theatre • Critical items : • Sterile, because of being used for penetrating skin or mucosa • Semi critical items : • In contact with skin or mucous membrane • Non critical items :
Aseptic techniques • Rules at clean zone • Procedures in sterile area • Talk as necessary • Restrict unnecessary movements • Sterile instruments, remove non sterile one • Avoid & Replace wet surgical drapes/towels
Hand washing • Indications: • Between patient contacts • Before performing or assisting with invasive procedures • Before taking care of particularly susceptible patients • Before and after touching wounds • Immediately after gloves are removed
Hand washing • Before and after performing sterile procedures • After contact with blood or body substances, mucous membranes, soiled linen, waste, or contaminated equipment. • Between tasks at different body sites on the same patient to prevent cross contamination • After taking care of infected patient • After touching contaminated inanimate sources
Preparation The procedure Hand washing
Purposes: • To remove debris and transient organisms from the nails, hands, and forearms. • To reduce the resident microbial count to a minimum. • To inhibit rapid rebound growth of microorganisms.
Purposes: • To minimize the re-growth of microorganisms for the length of the procedure. • To reduce the numbers of microorganisms on hands • To reduce contamination of the operative site by recognized or unrecognized breaks in surgical gloves.
Actual procedure: Strokes technique • Rinsing hands & arms • Scrubbing with antiseptic solution • Rinsing arms • Scrubbing with brush or sponge • Rinsing arms • Scrubbing with antiseptic solution • Drying arms
