With the rapid development of medical technology, high, precision, sharp continuous development, operating room safety management is particularly important. The error of the counting of the surgical articles causes the foreign body left in the patient’s body, which will cause irreversible damage to the patient and even cause the medical dispute and touch the legal problem. Operation items inventory system is an important working system in the operating room. Scientific and standardized methods and systems for counting surgical instruments and dressings during operation can prevent foreign bodies from being left in the body, prevent errors and accidents in the operating room, and are very important for ensuring the safety of the operation of patients. In order to ensure the safety of patients, it is necessary to ensure the correct inventory of surgical items. The factors affecting the accuracy of item counting in the operating room and the preventive measures are summarized as follows.展开更多

Methods: in January 2020, Lianyun District began to actively implement the preventive intervention measures of adverse reactions to pediatric DPT vaccination, Children who have completed the vaccination of prevention countermeasures in Lianyun District before the implementation of this study (January 1,2017 to December 31,2019) and after the implementation (January 1,2020 to December 31,2021). As the routine guidance group (23,921 doses) and the preventive intervention group (11,383 doses), monitoring the adverse reactions and satisfaction with vaccination care in both groups, analyze the effects of the preventive intervention. Results: the general response (0.31%) and total incidence of adverse reaction (0.31%) were significantly lower than the conventional guidance group (0.18%, 0.18%) (P <0.05), and the incidence of abnormal response between the two groups (P> 0.05). Parent satisfaction with vaccination care in the preventive intervention group (99.90%) was significantly higher than that in the conventional guidance group (92.75%) (P <0.05). Conclusion: there are some risks of adverse reactions after vaccination with DPT vaccine, mainly general reactions, which can reduce the risk of adverse reactions and have high application value, which is worth promotion and reference.展开更多

Because of its own rapidity and intuition, digestive endoscopy has been unanimously approved by medical staff and patients, and has also been more widely used in clinical medicine. With the change of lifestyle, more and more people suffer from diseases in the digestive tract. In order to achieve effective treatment and provide a more scientific basis for the operation, medical personnel must have an understanding of the actual disease situation of patients and accurately grasp the pathological changes of patients. This is also the main advantage of digestive endoscopy. In order to provide more safety guarantee for patients, the personnel using the digestive endoscope must have an understanding of the use method and basic structure of the digestive endoscope, be able to accurately judge the problems occurring in the use process of the digestive endoscope, carefully maintain and reduce the occurrence of faults, enable the equipment to have a longer use time, reduce the equipment maintenance consumption and maintain the normal operation of the hospital.展开更多

Pre-hospital emergency care plays an important role in rescuing patients and is a decisive factor in saving patients' lives. Nowadays, pre-hospital first aid mainly includes on-site first aid, monitoring of relevant vital signs sent to the hospital, and targeted treatment measures for different patients. Generally speaking, in pre-hospital first aid, due to the lack of first aid time and equipment, the possibility of dangerous situations in the first aid process increases, thus increasing the risk of first aid.展开更多

Compared with other breeding industries, sheep breeding has higher income. Therefore, sheep breeding in Inner Mongolia has also developed rapidly, forming a large-scale sheep industry belt, which brings higher economic benefits to local breeders. However, in the process of breeding, some breeders have not mastered scientific breeding techniques and adopted relatively few disease prevention measures, which affected the healthy growth of sheep. In order to improve the quality of sheep breeding, breeders should reasonably feed and optimize the feeding environment, and fully understand the common diseases and preventive measures in the growth process of sheep to increase economic benefits.展开更多

Methods Based on literature research, questionnaire survey and expert consultation, the causes of drug shortage in China were comprehensively investigated, and fishbone diagram was used to further analyze the logical relationship among the causes. Results and Conclusion The main reasons for the shortage of drugs are the low profit of production enterprises and insufficient active pharmaceutical ingredients (APIs). The other reasons include uncertain demand, standard problem and few exclusive manufacturers. Besides, the monopoly of circulation enterprises also leads to the shortage of drugs to a certain extent. It is suggested that we should increase the punishment of monopoly, optimize the market environment, and establish a reasonable drug price mechanism. In addition, enterprises should participate in the information communication platform of medical institutions to solve the asymmetry between supply and demand. The research on clinical drugs to substitute drugs in need should be strengthened, and the reporting system of drug discontinuation should be improved.展开更多

Affected by various factors, the water wall tube explosion of circulating fluidized bed boiler is very easy to occur during operation, which seriously affects the economic and safety benefits during the production, operation and construction of the enterprise. In view of this, taking 130t / h circulating fluidized bed boiler as an example, this paper puts forward the macro damage of the outlet nozzle of the circulating fluidized bed boiler, analyzes the macro and micro morphology of the fracture of the cracked pipe, and carries out micro hardness test and tensile test on the mechanical properties of the outlet nozzle. Finally, the reasons leading to the cracks in the export results are obtained, and the corresponding preventive countermeasures are formulated based on these reasons, in order to provide theoretical help for relevant staff.展开更多

In view of this, taking 130t / h circulating fluidized bed boiler as an example, this paper puts forward the macro damage of the outlet nozzle of the circulating fluidized bed boiler, analyzes the macro and micro morphology of the fracture of the cracked pipe, and carries out micro hardness test and tensile test on the mechanical properties of the outlet nozzle. Finally, the reasons leading to the cracks in the export results are obtained, and the corresponding preventive countermeasures are formulated based on these reasons, in order to provide theoretical help for relevant staff.
文摘Along with our country's current electrified railway scale overall growth and related operational work difficulty is also increasing, in this case, the relevant units to the current existing problems of catenary fault to fully grasp, and on the basis of the implementation of the strong operational work, and strengthen the overall quality of the railway transportation in China. This paper first discusses the importance of strengthening the operation and maintenance of the electrified railway catenary, on this basis, analyzes the specific reasons for the failure of the electrified railway catenary, and analyzes the relevant measures, in order to help the actual work.
