Sterilizing an operating theatre is an essential step in ensuring a safe and successful surgical procedure. It involves the thorough cleaning and disinfection of the room and equipment to eliminate any potential sources of infection. The following steps outline the process of sterilizing an operating theatre:
Clean the room: The first step in sterilizing an operating theatre is to thoroughly clean the room. This involves removing any visible dirt or debris and wiping down surfaces with a disinfectant solution. Make sure to pay extra attention to high-touch areas such as doorknobs, light switches, and countertops.
Disinfect the equipment: Next, all equipment and instruments used in the operating theatre must be disinfected. This can be done through a variety of methods, including autoclaving, cold sterilization, and chemical sterilization. Autoclaving involves using high pressure and steam to kill microorganisms, while cold sterilization involves using a chemical solution to kill germs. Chemical sterilization involves using a chemical solution to kill germs on equipment.
Sterilize linen: Linen such as towels, sheets, and gowns should also be sterilized to prevent the spread of infection. These items can be laundered using hot water and detergent, or they can be treated with a chemical sterilant.
Check the air quality: The air quality in the operating theatre should also be carefully monitored to ensure that it is free of contaminants. This can be achieved through the use of high-efficiency particulate air (HEPA) filters, which remove 99.97% of particles from the air.
Perform a final check: Before the surgical procedure begins, it is important to perform a final check of the operating theatre to ensure that it is clean and properly sterilized. This includes checking all equipment and instruments for cleanliness, as well as ensuring that the room is free of visible dirt or debris.
By following these steps, it is possible to effectively sterilize an operating theatre and create a safe and sterile environment for surgical procedures. This is critical for the well-being of both patients and healthcare providers, and it is an essential part of ensuring a successful outcome.
Disinfection, sterilization and operation theater guidelines for dermatosurgical practitioners in India
Iodine and iodophors have bactericidal activity against gram-positive, gram-negative, and certain spore-forming bacteria e. To reduce the electrical load consumption, a variable flow device can be installed which regulates the air-exchanges in the OR without the cooling effect. Grossly contaminated surfaces are the potential sources of hospital acquired infections. It is important to add KMnO 4 to all buckets simultaneously to reduce the exposure to fume i. Sterilization is intended to convey an absolute process. The majority of iodophor preparations used for hand hygiene contain 7.
Moist heat steam under pressure — this is the most common method in a practice. Alcohol will not work on wet hands as a disinfectant. For advanced and invasive procedures such as skin resurfacing, punch grafting, hair restoration, liposuction, complex closures, thorough hand scrubbing for 2 minutes with surgical scrub up to elbow is essential. A variety of sterilants and disinfectants are being used in health care facilities across the world. Surgical site infections SSIs are the second most common cause of hospital acquired Nosocomial infections.

Different colored bags for disposal of waste and sharps should be available and the color codes should be displayed prominently. Germicides categorized as chemical steriliants are high level disinfectants. Action: Put on a pair of surgical gloves — they do not need to be sterile at this stage. While using an alcohol-based hand rub, apply product to palm of one hand and rub hands together, covering all surfaces of hands and fingers, until the hands are dry. Use the three bucket system to mop the OT. Absolute sterility at the time of use is required for these items; consequently, one of the several accepted sterilization procedures is generally recommended.
These agents are dispersed with the aid of a fogger-like device inside the theatre environment. Disinfection Disinfection describes a process that eliminates most, if not all, pathogenic microorganisms, except bacterial spores. These complications of surgical procedures cause considerable morbidity and, when these occur deep at the site of the procedure, can lead to mortality as high as 77%. Under normal circumstances water cannot reach temperatures higher than boiling point before producing steam but if pressure is applied, the boiling point is raised and the temperature of the steam is higher. The following methods are practiced to keep the operation theatre OT bacteriologically safe and below accepted levels: 1. It needs to be carried out as per the established procedures and guidelines to ensure patient safety. A proper BMW process is needed for the proper functioning of any healthcare facility.
How are operation theatres sterilised and fumigated?
Bowie Dick tape — beige-coloured tape impregnated with a chemical strip that turns brown when it reaches a temperature of 121°C. It is usually done with formalin fumes, which are are very pungent and harmful. In a study carried out in Pune, antiseptic solutions in a large general hospital were found to be contaminated with pathogenic bacteria including Pseudomonas aeruginosa and Klebsiella species. After the sterilization process, the processed vial and an unprocessed control vial are crushed so that the inner chamber breaks mixing the broth and the spores. Rationale: This will trap tiny hairs, which may act as foreign bodies in an open wound or cause irritation in the eye. Hospital-acquired infection contributes to about 20% of admissions in the developing world. Once the sterile pack is opened, the contents become unsterile even if they are not used.

Microbiological sampling and surveillance of OT is also recommended to prevent HAIs. The pressure then builds up to 15 p. All the water used in the OT complex and Laboratories should be treated in a water chamber, with 5% sodium hypochlorite for 30 min in a ratio of 1:3 part of 5% sodium hypochlorite for 3 parts of wastewater before let out into the main sewer. The equipment should be kept immersed in glutaraldehyde solution for at least 45 minutes. Cleaning with detergent or carbolic acid is not required. Products for hand washing While choosing hand hygiene products, efficacy, irritancy potential, particularly when these products are used multiple times per shift, should be considered.
Disinfection and sterilization techniques of operation theatre: a review
It is usually used to sterilize things that may otherwise be damaged by heat e. They are also used to monitor ethylene oxide sterilizers. Decontaminating hands before having direct contact with patients is strongly recommended for implementation. It is a cationic bisbiguanide, and acts by disruption of cytoplasmic membranes, resulting in precipitation of cellular contents. Design and Disinfection of Operation Theater Detailed guidelines about dermatosurgery operation theater have previously been published and only a brief mention is made here. Cultures incubated at 37° for 48 h.
Plan of heating ventilation and air-conditioning system with air handling unit and laminar air flow plenum The size of the AHU and HEPA filters are in accordance to the volume of air inside the operation room. Sterilization takes 12 hours, followed by 2 hours ventilation and a further 24 hours for the gas to dissipate. AbstractModern day dermatologists conduct different esthetic and surgical procedures, with risk of infective complications. Proper protocols need to be put in place for proper adoption of these simple procedures by all theater staff. Blades shall be removed by an appropriate tool and discarded by the use of a tool. Instruments and different types of disinfection The precise type of disinfection depends on the type of instruments.
Generally, cleaning is designed to remove rather than to kill microorganisms. Formaldehyde fumigation has long been an accepted method of sterilization for areas where microbiological cleanliness is required. However, it is used inside ducting of HVAC system, pass boxes to disinfect the air. The room is opened after fumigation 12 - 24 hours. Rationale: They will not contaminate the site with minute threads or particles.
