Operation Theatre Fumigation

Introduction

Many hospitals around the world use large ozone generators to decontaminate operating rooms between surgeries. The rooms are cleaned and then sealed airtight before being filled with ozone which effectively kills or neutralizes all remaining bacteria. Fumigation is the process by which we can sterilize the enclosed area by injecting the chemical which will kill or destroy microbes present in the air. This process may be used in order to rid a home or other structure of insects such as termites or roaches, but it may also be used when products are being processed for export or import in order to rid the goods of exotic pests and organisms.

• It is very important to maintain good indoor air quality (IAQ) in Operation Rooms to ensure health and safety for the patient and surgical team. A significant consideration in Operation Theatres is the control of aerosols, anaesthesia gases and smoke. Aerosols are solid and liquid particles.
• It is very important to maintain good indoor air quality (IAQ) in Operation Rooms to ensure health and safety for the patient and surgical team.
• A significant consideration in Operation Theatres is the control of aerosols, anaesthesia gases and smoke. In Operation Theatres, however the main sources have an indoor origin are the patient, the surgical team and equipment. The anaesthesia gases dispersed in Operation Theatres are also considered as pollutants. The anaesthesia gases are dispersed in the environment through problems in the equipment and from the exhalations of the patient. Some gases used in the surgery. During surgery the highest concentration of gases is on the floor. However, with the movements of people these gases can be mixed with room air and inhaled by the surgical team.
• The concentration of gases in the Operation Room is critical and needs to be controlled; otherwise the productivity and quality of the work of the surgical team can decrease, and in the medium and long term health problems may occur.
• Halothane gas, for example, has a high toxicity and can affect the central nervous system. The gas concentration is controlled by the air change rate in the Operation Theatre by dilution to acceptable levels.
• The smoke can be generated by laser or electro surgery unit. “Research studies have confirmed that this smoke plume can contain toxic gases and vapours such as benzene, hydrogen cyanide, and Formaldehyde, bioaerosols, dead and live cellular material (including blood fragments), and viruses. At high concentrations the smoke causes ocular and upper respiratory tract irritation in health care personnel, and creates visual problems for the surgeon.
• In some critical situations the indoor air in Operation Room will be ultra-cleaned, for example, for orthopedic surgery, traumas, implants, burn patients, and other situations where the patient is immune compromised. Otherwise, when the surgery is septic, there should be also a higher control in the indoor environment, to protect the adjacent areas.
• Controlled Ozone is injected in the mainstream air in the return air duct. It is present in the indoor space at the times at low concentration. When it encounters chemical pollutants, it almost instantly oxidize them and keeps the indoor air free of chemical pollutants VOC as interferes with metabolism of cell multiplication of fungi resulting in the reduction of fungi along which is responsible for vide range of indoor related allergies.
• Use of Ozone Generator in Operation Theatre Fumigation will reduce the electricity consumption & also no long hour sterilisation before and after.
