RESUMEN
BACKGROUND: Coronavirus disease 2019 (COVID-19) is a major and costly public health emergency. AIM: To investigate the impact of China's lockdown policies during the COVID-19 outbreak on the level I trauma center of a tertiary comprehensive hospital of Traditional Chinese Medicine. METHODS: All patients admitted to our trauma center during a lockdown in 2020 and the same period in 2019 were enrolled. We collected data on demographics, daily visits, injury type, injury mechanism, injury severity score, and patient management for comparative analysis. RESULTS: The total number of patients in the trauma center of our hospital decreased by 50.38% during the COVID-19 Lockdown in 2020 compared to the same period in 2019. The average number of trauma visits per day in 2019 was 47.94, compared to 23.79 in 2020. Comparing the patients' demographic data, loss of employment was the most predominate characteristic in 2020 compared to 2019, while there was no significant difference in gender, age, and marital status between both periods. During the lockdown period, the proportion of traffic accident-related injuries, injuries due to falls greater than 1.5 m, and mechanical injuries decreased significantly, whereas the proportion of injuries caused by falls less than 1.5 m, cuts, assault, bites, and suicidal tendencies and other injuries increased relatively. In addition, the proportion of patients with minor injuries increased and serious injuries decreased during the lockdown. The hospitalization rate increased significantly, and there was no significant difference in emergency surgery and death rates. CONCLUSION: The lockdown policies during the COVID-19 outbreak significantly altered the number and mechanism of traumatic events in our hospital, which can be monitored regularly. Our results suggest that mandatory public health prevention and control measures by the government can reduce the incidence of traumatic events and the severity of traumatic injuries. Emergency surgery and mortality rates remain high, increased because of factors such as family injury and penetrating injury, and hospitalization rates have increased significantly. Therefore, our trauma center still needs to be fully staffed. Finally, from the perspective of the injury mechanism, indoor trauma is a major risk during a lockdown, and it is particularly important to develop prevention strategies for such trauma to reduce the medical burden of the next catastrophic epidemic.
RESUMEN
OBJECTIVE: To study the relationship between the solar term of onset of acute myocardial infarction (AMI) and its syndrome types in traditional Chinese medicine (TCM). METHODS: The clinical data about 430 patients with AMI hospitalized in Foshan Hospital of TCM from February 4th 2003 (Beginning of Spring) to February 3rd 2008 (Beginning of Spring) were collected, and the solar term of onset as angle coordinate was regarded, then the peak phase of the onset solar term in each syndrome type of AMI was calculated by circular statistical analysis. RESULTS: Among 430 patients with AMI, 134 patients were considered to have qi stagnancy and blood stasis syndrome, 188 patients showed the syndrome of turbid sputum obstruction, 29 of them showed deficiency of yin-blood, and 79 showed deficiency of yang qi. The clinical manifestation of AMI was mainly asthenia syndrome (qi stagnancy and blood stasis+turbid sputum obstruction, 74.9%). According to the circular statistical analysis, the peak of the solar terms of AMI onset occurred at the Beginning of Spring in all cases (r=0.127 4, P<0.01), and standard deviation (s)=116.300 6 degree angle, showed it mainly occurred in winter and spring. As the peak of the onset of qi stagnancy and blood stasis occurred at Winter Solstice and Lesser Cold (r=0.200 5, P<0.01), its peak occurred in winter; the turbid sputum obstruction syndrome occurred at Spring Equinox (r=0.147 0, P<0.05), mainly in spring, yet the symptoms of above two peaks were generally mild. Besides, there was no significant difference in onset of the solar term in regard to onset of deficiency of yin-blood and deficiency of yang qi (both P>0.05). CONCLUSION: There is a close relationship between periodicity of the solar terms and onset of AMI. The main treatment for AMI is to expel turbid sputum, activate blood to resolve stasis and promote blood circulation to relieve pain; also the method of activating blood to resolve stasis is frequently contemplated in winter, and the method of expelling turbid sputum is the main strategy in spring.
