The hospital took multiple measures to strengthen radiation prevention management and protect the safety of doctors and patients

Recently, a number of hospitals have taken active actions to take a series of effective measures to strengthen radiation prevention management and create a safe diagnosis and treatment environment for doctors and patients.
At present, with the continuous progress of medical technology, all kinds of radiation diagnosis and treatment equipment play a key role in the diagnosis and treatment of diseases, but the radiation safety problem can not be ignored. The Department of Cardiovascular Medicine of the 986 Hospital of the Air Force successfully completed the first T3D (three-dimensional mapping system) combined with ICE (intracardiac ultrasound) guided zero-ray radiofrequency ablation of atrial fibrillation. Traditional radiofrency ablation procedures are performed under X-ray fluoroscopy, exposing patients and medical staff to a certain amount of radiation, and this new technology completely avoids the use of X-rays, not only freeing doctors from heavy “lead armor”, but also providing a safer treatment option for patients who are not eligible for radiation. It marks a new level of radiofrequency ablation of arrhythmia in hospitals.
At the same time, Fudan University affiliated Zhongshan Hospital also came good news. The world’s first “zero noise” DSA (Digital subtraction angiography) percutaneous coronary intervention was successfully performed at the hospital. Ge Junbo, academician of the Chinese Academy of Sciences and professor of Zhongshan Hospital, performs complex operations for patients with the help of the “zero-noise” DSA device developed by Lianying Medical. The device comes from the key research and development project of the Ministry of Science and Technology’s “13th Five-Year Plan” digital diagnosis and treatment equipment. Through hardware and software optimization, the interfering noise in the image is almost completely disappeared, the spatial resolution of the image is increased by 57%, the signal-to-noise ratio is increased by more than 4 times, the contrast radiation dose is reduced by at least 70%, which greatly improves the medical experience of patients and reduces the side effects and complications after surgery. It also gives maximum protection to doctors who have been exposed to radiation for a long time.
In addition to the application of new technologies, local regulatory authorities and hospitals are also strengthening management. When the law enforcement personnel of Luqiao District Health Bureau of Taizhou City carried out supervision and inspection on a hospital, they found that the CT room area of the 2nd floor and the minimum unilateral length did not meet the regulations, and they were warned and fined according to law. This also reminds medical institutions that the construction and renovation of radiological diagnosis and treatment places such as CT room must strictly follow the relevant standards and procedures, such as the shielding lead equivalent of CT room should be ≥2.5mmPb, and the reconstruction should go through multiple stages such as pre-evaluation of occupational hazard radiation protection and completion acceptance to ensure radiation safety.
In addition, the Shenzhen Municipal Bureau of Ecological Environment has promoted the construction of radiation safety standardization in pet hospitals by compiling the Guidelines for the Construction of radiation Safety Standardization in the use Places of Animal Diagnostic X-ray Devices in Shenzhen. In view of the weak awareness of radiation safety management and other problems existing in pet hospitals, we not only organize professional on-site assistance, but also establish a radiation safety consulting wechat group and hold online training meetings to help pet hospitals improve the level of radiation safety management and eliminate radiation safety hazards from the source.
Hospital radiation prevention work is related to the health and safety of doctors and patients, the application of new technologies and strict management measures are bringing new changes to this field, and will continue to promote the medical industry in the future to improve radiation safety, to provide more reliable protection for patients and medical staff.
