(1) Strengthen the consciousness of control and management of clean operating room
At present, there is a wrong idea that it is safe to operate in the clean operation department. There is no need to seek aseptic technology immediately. It can save all kinds of surface disinfection work, and it does not need to be as troublesome as in the past.
Clean technology can effectively control the infection caused by pathogenic bacteria through air, but it has no function of disinfection and sterilization, nor can it control the pollution sources brought into the operating room by other ways.
For example, incomplete disinfection of medical staff and patients, incomplete disinfection of medical instruments and equipment, and turbulence in the operation area caused by various factors that may lead to laminar flow transition (from laminar flow to turbulence), may produce new contact pollution sources.
Surface microbiology has a very important theory: "Anything that can be transmitted by contact can be transmitted by aerosol". That is to say, surface microorganisms can exchange with air microorganisms.
This theory has special significance for the clean operation department. It can be understood as that if the clean operating room is empty or static, the dynamic cleanliness will not be good if the microorganisms on the human body, instruments and environmental surface are not controlled properly. That is to say, the control of surgical infection is still empty talk.
Clean operation Department is not the "universal safe" to prevent and control infection. High efficiency filter is not the only condition to maintain air cleanliness. Modern scientific management is closely related to the application effect.
(2) Emphasizing the Important Contents of Scientific Management
1. Looking from many clean operation departments that have been built up, the major work defects occur in the equipment layer or the cleaning room.
2. An engineering maintenance department with professional skills shall be established, professional clean technology training shall be organized, work shall be carried out in a standardized way, maintenance records shall be made carefully and strictly, and shall be properly kept for future reference.
3. Check and maintain clean air conditioning units frequently. Check once a month to clean the interior, especially the heat exchanger, with high-pressure water.
4. Strengthen the inspection and maintenance of fresh air units. Check once a day to keep the interior clean; clean the crude filter every two days, replace the crude filter for 1-2 months; clean the medium-effect filter once a week, replace it for 3 months; replace the sub-high-efficiency filter once a year.
5. High-efficiency filters are checked every six months to see if the cleanliness meets the requirements. When the resistance exceeds 2 times of the initial design resistance or has been in use for more than 3 years, it should be replaced.
6. Medium efficiency (or high efficiency filter) in exhaust fan set should be replaced every year. If special contamination operation is performed, every case of operation must be replaced, and the filters must be sealed and transported out and incinerated.
7. Ceiling ceiling air supply ceiling should be inspected once a month. The inner surface of diffusion plate should be cleaned with medical alcohol (except leak-proof ceiling).
8. The return air filter should be checked regularly and replaced once a year. If special contaminated operation is performed, each operation must be replaced, sealed, removed and incinerated, and wiped with disinfectant back to the inner and outer surfaces of the tuyere. If a general contaminated operation is performed, disinfectant must be used immediately after each operation and thoroughly cleaned.

9. In recent years, China has taken the establishment of a clean operating Department (room) as one of the necessary measures to improve medical quality and avoid hospital infection. However, the construction of clean surgery department in China is still at the initial stage, the construction market is chaotic and the quality is worrying. Therefore, it is the precondition and foundation for the operation and management of the clean operation Department to control the quality of the project construction and strictly standardize the construction standards.

(3) Controlling the Important Indicators of Scientific Monitoring
To carry out professional daily monitoring is an effective means to do a good job in the management of clean operation department.
It is suggested that routine projects should be set up as follows: sedimentation bacteria concentration, suspended bacteria concentration, dust concentration, pressure difference, wind speed and air volume, temperature and relative humidity.
Suspension bacterium concentration: It is mainly used to dynamically monitor the actual bacterial concentration in the operation state, and to detect and predict the risk of infection under special surgical factors.
Dust Concentration: It is mainly used to monitor the static cleanliness level. The number of dust particles larger than or equal to 0.5 micron and more than 5 micron is detected by fixed-point positioning.
Pressure difference: It is mainly used to monitor the normal pressure difference in each area of the clean operation Department to prevent the operation infection caused by the wrong direction of air flow.
Wind Speed and Volume: The code requires that the cross-section wind speed should be controlled in the range of 0.25-0.3m/s on the working face of the local 100-level working area. If less than 0.25m/s may affect the anti-interference ability, too large can cause excessive loss of water in the incision, especially in ophthalmic surgery, the wind speed is too high, which will make conjunctiva evaporate quickly and lose water, affecting the whole operation.
Class II and III clean operating rooms adopt a low turbulence displacement airflow, which is the filling principle, and the outflow speed is not less than 0.15m/s.
Class IV quasi-clean operating room according to general turbulence parameters is the dilution principle, the outlet wind speed is not less than 0.25m/s, in order to maintain momentum to send the air down.
Minimum fresh air volume: Requirements to meet the following conditions to take the maximum: (1) 60 m3 per hour; (2) Compensation for indoor exhaust, and can maintain the indoor positive pressure value of fresh air volume; (3) the minimum fresh air volume specified in the code.
Temperature: The norm requires that the temperature be controlled at 22-25 C. The temperature of the operating environment is closely related to the infection rate of the incision. Temperature control is actually an effective means to control the concentration of bacteria. For example, exceeding the upper limit of temperature will lead to an increase in the number of bacteria in the body of medical staff.
Relative humidity: The standard requirement is 40%-60%. Relative humidity is closely related to the survival rate of bacteria. Appropriate water is the nutritional source of bacteria. According to the study, when the relative humidity is 50%, the bacteria die in 10 minutes. When the relative humidity is higher or lower, most bacteria are still alive even after 24 hours. At room temperature, mildew can occur when the relative humidity is more than 60%. More than 80% of the relative humidity will be mildewed regardless of the temperature.
