ObjectiveBy summarizing the clinical characteristics of perioperative patients with cross infection of novel coronavirus in thoracic surgery ward, to guide the prevention and treatment of nosocomial infection during the anti-epidemic period.MethodsThe clinical data of 451 patients with chest diseases in the Department of Thoracic Surgery of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from January 1st to 24th, 2020 were analyzed and followed up. There were 245 surgical patients and 206 non-surgical patients.ResultsIn the department, 7 patients (7/451, 1.55%) were infected with the novel coronavirus and all of them were surgical patients, whose preoperative imaging data did not reveal the imaging changes of novel coronavirus. There were 5 males and 2 females, aged 56 to 68 years. The patients with old age, smoking, surgery, coronary heart disease, chronic liver disease and tumor history were more susceptible to infection. From the spatial distribution of patient beds, it was found that the distance among infected patients was greater than 1 m, and no cross infection was found in the other patients of the same ward. During follow-up, two family members of noninfected patients were found to be infected one week after discharge. However, there was no overlap of spatiotemporal distribution between the family members and the infected patients during the hospitalization period.ConclusionThe novel coronavirus pneumonia rate in the department of thoracic surgery is low, which may be opportunistic infection. At the same time, a good control and prevention of epidemic disease can reduce the occurrence of cross infection in the department of thoracic surgery.
ObjectiveTo investigate the prevention and control measures and procedures for surgical operation safety during the outbreak of new coronavirus pneumonia.MethodsAfter interpreting the diagnosis and treatment plan of new coronavirus pneumonia, the prevention and control plan of new coronavirus pneumonia, and the technical guidelines for prevention and control of new coronavirus pneumonia infection in medical institutions, we formulated and improved the prevention and control measures and procedures for surgical safety in our hospital.ResultsA total of 567 patients were operated in our hospital from January 22, 2020 to February 10, 2020, including 501 were operated in the surgical center and 66 were operated in the interventional center. Among all the cases, there were 303 emergency operation and 264 scheduled or limited operation. In the emergency operation, the top three were 130 cases of caesarean section (42.9%), 63 cases of abdominal digestive system operation (20.8%) and 31 cases of skull operation (10.2%). In the scheduled or limited operation, the top four were 65 cases of benign diseases of the eye (24.6%), 57 cases of tumor (21.6%), 53 cases of orthopedic surgery (20.1%), and 25 cases of coronary angiography (9.4%). All the patients were successfully completed the operation and recovered well after the operation. No serious surgical complications or infection-related complications occurred.ConclusionDuring the outbreak of new coronavirus pneumonia, surgery and epidemic prevention and control can be carried out by adjusting and optimizing measures and procedures.
ObjectiveTo investigate the strategy adjustment of breast cancer surgery management process during the outbreak of novel coronavirus pneumonia (NCP), and to summarize the experience.MethodsBased on "Pneumonitis Diagnosis and Treatment Plan for Novel Coronavirus Infection (Fifth Trial Version)" and "Surgery Work System During the Prevention and Control of Novel Coronavirus Infection in Mianyang Central Hospital (Second Edition)", the breast surgery department adjusted strategies and plans for breast cancer surgery during the epidemic.ResultsFrom January 25, 2020 to February 11, 2020, 8 cases of breast cancer surgery were performed in our hospital. They were all females, with an average age of 45 years. Five patients underwent modified radical mastectomy, 2 patients underwent breast-conserving surgery plus sentinel lymph nodes biopsy, and 1 case underwent breast-conserving surgery plus axillary lymph node dissection. All 8 patients were diagnosed as invasive ductal carcinoma of breast by hollow needle biopsy. All patients recovered smoothly after surgery, no complications occurred, and they were discharged as planned. No patients or medical staff showed NCP exposure and infection.ConclusionDuring the NCP epidemic, breast cancer surgery can be performed and the epidemic can be effectively prevented and controlled by adjusting the work flow and strategy.
The coronavirus disease 2019 (COVID-19) epidemic has had a serious impact in the world. In the absence of vaccines and therapeutic drugs, disinfection has become an important technical means to block the spread of the virus. By analyzing the characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), we studied a series of disinfection technologies for COVID-19. During the outbreak of COVID-19, Jinan Second Center for Disease Control and Prevention disinfected the houses of the cases to be investigated in a community. The effectiveness of the disinfection technology was verified through the process of disinfection preparation, sampling before disinfection, field disinfection, sampling after disinfection and evaluation of disinfection effect. Compared the data before and after disinfection, the killing rate of the total bacterial colonies in the air and on the surface of the object was more than or equal to 90%, and no SARS-CoV-2 was detected after disinfection. The results show that the disinfection effect of the disinfection technology meets the standard. Finally, through the analysis of the wrong way of disinfection and the harm of over disinfection, the importance of scientific disinfection and precise disinfection are emphasized, and the research has a good guiding value for prevention and control of the epidemic.
Objective To design a nucleic acid information early warning system and evaluate the effect of the application. Methods 60 nurses working in the clinical department of Zhongnan Hospital of Wuhan University from August to October 2021 were selected by convenient sampling method, and the included nurses were divided into experimental group and control group. The experimental group used the nucleic acid information early warning system, and the control group used the nucleic acid registration in a common way. Statistical duration of the nucleic acid information, nucleic acid leakage detection rate and nurses job satisfaction after application were compared between the two groups. Results After the application of nucleic acid information early warning system, compared with the control group, the statistical duration of the nucleic acid information in the experimental group was shortened [(2.0±0.4) vs. (3.8±0.7) min; t=25.827, P<0.001], nucleic acid leakage detection rate decreased [1.4% vs. 6.9%; P=0.019]. The job satisfaction of the experimental group was higher than that of the control group (P<0.001). Conclusions Applying the nucleic acid information early warning system could reduce statistical duration of the nucleic acid information, nucleic acid leakage detection rate and improve nurses job satisfaction and work experience. It will provide reference and basis for medical institutions to normalize the management of nucleic acid prevention and control in medical institutions.
