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. Infection Control Why should we apply a and antiseptic techniques ? 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 Anti septic 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 % sodiumhydroxide being added The Operating Theater Transitional Zone Clean Zone Semi – Restricted Area S C R U B S U I T Restricted area Sterile core 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 Scrub Area (Video) Sterile Core (Video) 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 Surgical attire Male personnel Female personnel Personnel with veil 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 Aseptic techniques 1. 2. 3. 4. 5. 6. 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 Hand washing Preparation The procedure Surgical Scrubbing Procedure 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. Preparation: Recognizing glove sizes 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 Actual procedure: Five minute technique Gowning The goal: – to ensure a safe, protective, and aseptic environment to the patient and the surgical team. Gowning & closed gloving techniques Drying hands with sterile towel Applying gown Closed gloving technique – The final step of the aseptic techniques before performing surgery. – Sterile gloves are worn to permit the wearer to handle sterile supplies or tissues of the operative wound. – Sterile gloves establish a shield that protects the patient from contamination by flora from the hands of health care workers. Open technique Closed technique Skin preparation The goals: – to cleanse the skin and bring both the resident and transient bacterial counts to an irreducible minimum, therefore reducing the risk of wound contamination and subsequent surgical site infection. performed just before the surgical incision has been performed. Skin preparation Skin painting Skin draping Ready for surgery Gown and gloves removal After surgery: Gown, Gloves removal Simultaneous removal
