Hospitals are known to all. They are places where people are treated and saved. The hospital operating room is a very important place to operate on people. Now many operating rooms are clean operating rooms, which is to avoid infection of patients'wounds, leading to the failure of the operation. But sometimes the clean operating room will still be infected, which needs to be handled carefully. What factors can cause infection in a clean operating room?
1. Designing a clean operating room requires scientific design and planning for operations in different departments, such as anorectal surgery, gynecology and obstetrics, general surgery, etc. The 10000-class clean operating room is generally used for brain surgery, orthopaedics and urology, while for joint replacement, extracerebral surgery, cardiac surgery and ophthalmology, 100-class clean operating room is required. Class I special clean operating room.
2. Medical personnel are the important implementers of the operation, and they will be exposed to dangerous incisions and other parts. Therefore, medical personnel should carry out standardized surgical brushing and aseptic technical operations to prevent nosocomial infection caused by pathogenic bacteria in medical personnel or operating room environment. Howard et al. summarized several important principles for optimizing environmental risk factors in clean operating rooms to reduce the incidence of infection during plastic surgery.
3. Patients with diabetes mellitus or infection have complications such as diabetes mellitus or infection focus, and the surgical site near the infection focus or bacteria will spread through blood circulation or lymphatic circulation in the body. At the same time, the instruments used by the operator may be contaminated by bacteria, if not replaced in time, it will cause infection. Lipp et al. have made some achievements in reducing the probability of surgical site infection by using microbial sealants.
4. Air quality management in air-polluted operating rooms is a dynamic process. In addition to regular thorough cleaning of the operating room, it should be cleaned and maintained in time before and after the operation, and the value of planktonic bacteria should be measured. According to WHO reports, the infection rate of air-polluted operating rooms will increase significantly if the number of planktonic bacteria reaches 1000-1800 cfu/m.
These factors will make the clean operating room infected, we must pay attention to, after all, the operating room can not be infected, light surgery failure, heavy will also make the lives of patients threatened.
