The new coronavirus epidemic has made everyone more anxious. When people have nothing to do at home, they always wash their hands, but ignore the dead ends of cleaning the room. Not only do you wash your hands often, but more importantly, the toilets, sinks, and other toiletries in the bathroom. It is right to wash your hands often, but sit down and go to the bathroom. The microenvironment of brushing and washing your face is full of "mines" buried by the new coronavirus, which will infect your family immediately upon contact, making them "unable to prevent". Especially for suspected patients who are isolated from each other at home, or when their family members have flu-like symptoms, they must share bathrooms or toilets, and pay special attention to cleaning potential sources of infection in small home environments. This is a painful lesson learned from some new cases of coronavirus infections observed in the past two months. Let's look at the hospital environment again: Fever clinics and emergency rooms are generally considered a high-risk environment and are very protective sectors. Also, where are cross infections or omissions most likely to occur? Although during the epidemic, some patients with acute or chronic diseases still need to go to the hospital. In the hospital environment, the radiology department, b-ultrasound room and intervention room are one of the potential high-risk places! The latest American Journal of Radiology has published a comparison of microenvironmental surveys conducted by hospital experts in Singapore during the SARS period with newly diagnosed coronavirus (SARS type 2) in radiology departments, b-ultrasound rooms, angiography rooms and other departments. The probability of cross-infection is extremely high and the risk is extremely high. The imaging department, b-ultrasound room and intervention room are mainly used to prevent radiation risks. The operating space is mostly enclosed. Once patients carry the virus, the imaging department is not a clinical front-line service department, and it has great potential risks for staff and other patients. Unlike medical staff such as fever clinics and emergency rooms, they are easily paralyzed by the assistant diagnostic department. According to the experience of experts from Singapore Central Hospital in comparing the SARS epidemic, it was pointed out that during the SARS epidemic in 2003, portable imaging aids were widely used, and imaging staff were most likely to directly contact or contact patients. In the imaging department and interventional imaging room, patients in different departments include inpatients, outpatients, fever and non-fever patients, accompanying family members, visitors and medical staff in other departments. May come and go together. Therefore, if the imaging department's cross-infection and infection prevention and control mechanisms are slightly negligent or violate operating procedures, serious consequences will result. In some large hospitals, it may be standardized and strictly managed. However, small environments such as county hospitals and primary medical institutions, including businesses, factories and mines, various health check centers, and radiology departments will be high-risk areas for infectious diseases. During the epidemic, special personnel will be set up at the entrance of the Imaging Section to check the protection of personal protective equipment such as masks worn by staff and to prevent accompanying persons from entering. The American Journal of Radiology announced the practice of posting personal protective equipment reminders on doors in Singapore hospitals; reminding employees to wear personal protective equipment properly before entering the room. Identify the following three key operating procedures and reviews, including personnel, site and equipment; procedures and rules. Involving radiologists, technicians, professional medical personnel such as angiography and interventional therapy; nuclear medicine and molecular imaging department, radiographic technicians, nursing staff and accompanying family members, etc. All personnel on-site and equipment requirements Personal protective equipment for employees; Dedicated "scanning equipment" for isolation and high-risk patients; physical security and access control; secure isolation in alternative work areas; protection and security of portable imaging equipment; procedures and policy reviews Policies, regulations and procedures
