ABSTRACT
Background: As increasing cases of COVID-19 around world, urgent need for effective COVID-19-specific therapeutic drugs is necessary; therefore, we conducted a pilot randomized-controlled study to evaluate the efficacy of 99mTc-MDP for COVID-19 therapeutic treatment. Methods: A total of 21 mild patients with COVID-19 were enrolled in this pilot RCT from February 2020 through March 2020, and then were assigned, in a 1:1 ratio, into control (11 patients) and 99mTc-MDP group (10 patients). Patients in the control group received routine treatment and patients assigned to the 99mTc-MDP group received a combination of routine treatment and an administration of 99mTc-MDP injection of 5ml/day. Both of the patients in the control and 99mTc-MDP groups were treated for 7 days with the primary end point of CT-based radiological pulmonary changes during 7-day follow-up. Findings: From baseline to the day 7, 8 (80%) of 10 mild patients in the 99mTc-MDP group had a significant radiological improvement in lung and a decline in inflammatory infiltration, whereas only 1 (9.1%) of 11 patients in the control group had a radiological improvement in lung. None of the patients in the 99mTc-MDP group had disease progression from mild to severe, as well as an inflammatory cytokine storm, and 2 mild patients (18.2%) in the control group developed severe. During days 7 through 14, the number of patients with radiological improvement in the 99mTc-MDP group remained consistent, and only 1 additional case (22%) in the control group were reported. Conclusion: In this randomized pilot study, 99mTc-MDP had an effective inhibitory effect on the inflammatory disease progression for the therapy of COVID-19, and it can accelerate the absorption of pulmonary inflammation in a short period of time during the process of treatment.

Objective@#To report our experience in the prevention and control of COVID-19 in the tramatological and microsurgical wards.@*Methods@#A retrospective study was conducted of the COVID-19 infections in the 51 medical staff and patients from 31 December, 2019 to 14 February, 2020 at Department of Traumatology and Microsurgery, Zhongnan Hospital. The prevention and control measures were upgraded after 20 January, 2020 to address the serious epidemic situation, including preventive disinfection, terminal disinfection and personnel disinfection in wards, management of emergency patients, inpatients and patients suspected of COVID-19 infection, and training, management and psychological intervention of medical staff. The outcomes resulting from different prevention and control measures before and after 20 January, 2020 were compared.@*Results@#From 31 December, 2019 to 20 January, 2020, there were altogether 3 cases of definite COVID-19 infection and 2 ones of suspected COVID-19 infection at the department. One doctor, one technician and one nurse were diagnosed as definite COVID-19 infection while one nurse and one patient as suspected COVID-19 infection. The 4 medical staff members infected were cured and discharged before 14 February, 2020 but unfortunately the one patient infected died. After the prevention and control measures for COVID-19 infection had been upgraded since 20 January, 2020, 12 out of the 29 emergency patients at our wards had fever (body temperature ≥37.3℃) but none COVID-19 infection. All the 47 medical staff on duty at the department got trained and none of them was infected by COVID-19 or suffered from mental disorder.@*Conclusion@#In the epidemic of COVID-19, as our prevention and control measures for COVID-19 infection were adjusted and upgraded in response to the changing epidemic situation, they eliminated nosocomial infection scientifically and effectively and ensured life safety of the medical staff and patients at the department.
ABSTRACT
Objective@#To suggest strategies for emergency diagnosis and treatment of trauma orthopedics in the epidemic period of Corona Virus Disease 2019(COVID-19).@*Methods@#In the epidemic of COVID-19 from January 21 to February 15, 2020, 128 patients with orthopaedic trauma sought emergency treatment at Department of Orthopedic Surgery, The People’s Hospital of Wuhan University. They were 71 males and 57 females with an average age of 48.7 years (from 5 to 88 years).Of them, 107 cases were treated at the outpatient department and 21 hospitalized. Emergency operations were carried out for 4 cases and selective operationsfor 17 cases. COVID-19 infections were recorded in the patients and medical staff as well. Measures taken and experiences learned were summarized since the epidemicoutbreak of COVID-19.@*Results@#Of the 107 cases treated at the outpatient department, 3 had a definite diagnosis of COVID-19 and 3 a suspected diagnosis of COVID-19. Of the 4 cases undergoing emergency surgery, one was suspected of having COVID-19. Of the 17 cases undergoing selective surgery, one was diagnosed definitely as COVID-19and 2 were suspected of COVID-19. Two nurses were diagnosed definitely as having mildCOVID-19.One doctor and one nurse were suspected of COVID-19. Since the COVID-19 infections in medical staff occurred all before the preventive and control measures for COVID-19 had been implemented,is was not ruled out that their infections might have come from communities.@*Conclusions@#It is particularly important for medical institutions of all levels to maintain safe and effective routine services while doing well in COVID-19 prevention. In the epidemic of COVID-19, front-line medical staff in emergency traumatic orthopedics is faced with great challenges in the process of diagnosing and treating patients. High-quality and safe medical services can be provided as long as nosocomial COVID-19infection is effectively controlled by rigid screening of patientsnewly admitted, classified management of inpatients, optimal management of inpatient wards, standard preventive measures in perioperative period, a perfect system for medical protection, and medical education for patients and their carers.
