Objective To investigate the adverse drug reactions (ADRs) of patients with SARS in Xiao Tang Shan Hospital. Methods We developed and distributed Drug Use Handbook and established ADRs monitoring group to guide resaonable drug use. We followed up the process and collected clinical report on ADRs. We retrospectively analyzed the data on ADRs by the classification and grade of ADRs according to WHO and Hospital Information Sysytem (HIS) of Chinese PLA General Hospital. Results We collected 193 (87 males and 106 females) patients with ADRs among 680 SARS patients with incidence rate of ADRs of 28.38%. The ADRs incidence rate was higher in females and elders. Critical SARS patients and SARS patients with diabetes were more susceptible to ADRs. Large dosage and combination of drugs may induce ADRs. Steroids may be a main cause of ADRs. The ADRs incidence rate induced by injection was higher than that induced by all kinds of oral drugs. ADRs mainly happened in hematological, endocrine and digestive systems. Conclusion SARS patients are prescribed many kinds of medications. Large dosage of so many medications may lend to high incidence rate of ADRs. Steroid should be cautiously used in the treatment of SARS.
Objective To investigate the quality of the randomized controlled trials (RCTs) of traditional Chinese medicine (TCM) integrated with western medicine for severe acute respiratory syndrome (SARS). Method All the randomized controlled trials of traditional Chinese medicine integrated with western medicine for SARS worldwide were gained by electronic searching and hand searching. The quality of the RCTs was analyzed by the quality grade evaluation used in Cochrane handbook.The sample size, the baseline data, the results indexes were also analyzed. Results Seven RCTs included 501 SARS cases were identified. The quality grade of one RCT is B, the other six RCTs were graded C. None pre-specified sample size. One RCT tested the differences of the baseline data by statistic method. One RCT reported quality of life as result index. None reported the adverse events.Conclusions Current RCTs of TCM integrated with western medicine can’t provide b evidence for clinical practice because of the poor quality.
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.
The diagnosis of coronavirus disease 2019 should not only depend on nucleic acid test, but also be based on clinical information such as medical history and radiographic findings. It’s critical to identify patients with high risk of rapid progression. Treatment of coronavirus disease 2019 should be individualized according to the underlying diseases and progression manner. For severely ill patients, oxygen and nutrition supplementation need to be strengthened, and for some highly selected cases, administration of glucocorticoids might be beneficial.
Objective To assess the effect of integrated traditional Chinese medicine with western medicine (ICWM) in the treatment of SARS. Methods We searched MEDLINE, EMBASE, and Chinese BioMed Database ( CBM ) , and the Intemet performed handsearching in Chinese journals and reference lists. We included randomised controlled trials and prospective controlled studies of integrated Chinese medicine with western medicine versus western medicine alone in people with SARS. Three independent reviewers collected details of study population, interventions, and outcomes using a data extraction form. We conducted meta-analysis for similar data of studies.Results Nine studies (n =812) were included, all with the possibility of containing serious bias. ICWM in the treatment of SARS was associated with the following reductions: case fatality [ OR 0.32, 95% CI (0.14,0.71 ) ] , fever clearance time [ WMD -1.17, 95% CI ( -1.83, -0.50 ) , symptom remission time [ WMD-1.47, 95% CI ( - 1.96, - 0. 98) ] and the number of inflammation absorption cases [ MD 1.63, 95% CI(0.95, 2.80 ) ], having no significant difference in symptom scores of convalescents [ WMD -1.25, 95% CI ( -2.71, 0.21 ) ], cumulative dose of corticosteroids [ WMD - 236.96, 95% CI ( - 490.64, 16.73) ] and inflammation absorption mean time [ WMD 0.63, 95% CI ( - 1.33, 2.59) ] .Conclusions Due to the methodological limitations of the studies, the effect of ICWM for SARS is unclear. The apparent improvements in cases fatality, fever clearance time, syndromes remission time and numbers of inflammation absorption cases warrant further evaluation with high quality and large scale trials to be expected.
ObjectiveTo use failure mode and effect analysis (FMEA) to check and improve the risk of severe acute respiratory syndrome coronavirus 2 nucleic acid detection, and explore the application effect of FMEA in the emergency inspection items.MethodsFMEA was used to sort out the whole process of severe acute respiratory syndrome coronavirus 2 nucleic acid detection from January 30 to February 21, 2020. By establishing the theme, setting up a team, analyzing the failure mode and potential influencing factors. Then calculate the risk priority number (RPN), formulate preventive measures and implement continuous improvement according to the analysis results.ResultsA total of 2 138 cases were included. After improvement, the number of potential failure modes has been reduced by 2 (17 vs.19); the value of total RPN decreased (3 527.49 vs. 1 858.28). There was significant difference in average RPN before and after improvement [(185.66±74.34) vs. (97.80±37.97); t=6.128, P<0.001].ConclusionsIn the early stage of emergency inspection items, using FMEA can systematically check the risk factors in the process, develop improvement measures. It also can effectively reduce the risk of severe acute respiratory syndrome coronavirus 2 nucleic acid detection in hospital.
Coronavirus disease 2019 has been widespread in Hubei province since the beginning of 2020. Many medical teams went to aid Hubei from the whole country. The medical team of West China Hospital of Sichuan University arrived in Jianghan district of Wuhan on January 25, 2020. As one of the earliest teams arriving Hubei, we explored the measures for infection prevention and control of resident, in order to reduce the risk for infection of medical team. The infection prevention and control experiences on the establishment of infection control team, process management, behavior management, clean disinfection, infection monitoring and emergency response and emergency response to exposure of the medical team of West China Hospital were summarized in this article.
Currently, coronavirus disease 2019 (COVID-19) is still widely prevalent around the world, leading to a major threat to the global public health. COVID-19 mainly involves the respiratory system, but extrapulmonary manifestations including that of the nervous system also exist in the setting of COVID-19. Misdiagnosis and delayed treatment of the disease may easily cause when ocular, especially neuro-ophthalmological symptoms are the first symptoms in early COVID-19, as the neuroophthalmological manifestations are rarely reported. First-line clinicians need to ask about not only respiratory symptoms such as fever, cough and sore throat, but also diplopia, impaired vision, eye motion pain, abnormal gait or other neurological deficits at the first reception, as these extrapulmonary manifestations are often signs of serious infection. The neuroophthalmological manifestations and possible underlying etiology of COVID-19 were summarized in this review, hoping to provide an early identification and effective treatment of COVID-19 for clinicians. More extensive studies are needed in the future to confirm the causal relationship between COVID-19 and neuroophthalmological disease to provide a sufficient basis for a comprehensive understanding of COVID-19.
Objective To explore the clinical characteristics of patients who were infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) of different genotypes. Methods A retrospective study was conducted on 111 SARS-CoV-2 infected cases at home and abroad admitted to Chengdu Public Health Clinical Medical Center between January and September 2020. The basic information, gene sequencing results (Pangolin typing method), clinical typing, first laboratory examinations 24 hours after admission, and whether repositive after discharge were collected. According to Pangolin typing, patients were divided into five groups: A, B, B.X, B.1.X and B.1.1.X. The basic information (age, sex, and origin), laboratory test results (lymphocyte count, C-reactive protein, serum amyloid A, CD3+ T lymphocytes, CD4+ T lymphocytes, and CD8+ T lymphocytes), clinical classification and whether repositive were compared among different genotype infected patients. Results Among the 111 infected patients, 54 (48.6%) were males and 57 (51.4%) were females. Their ages ranged from 16 to 87 years, with a median age of 49 years. In terms of clinical classification, there were 10 asymptomatic cases (9.0%), 10 mild cases (9.0%), 64 ordinary cases (57.7%), 13 severe cases (11.7%), and 14 critical cases (12.6%). There were 75 domestic cases (67.6%) and 36 imported cases (32.4%). Eighty cases (72.1%) did not return to positive, and 31 cases (27.9%) returned to positive. There were 8 cases infected by type A virus, 18 cases infected by type B virus, 26 cases infected by type B.X virus, 5 cases infected by type B.1.X virus, and 54 cases infected by type B.1.1.X virus. Among patients infected by different genotype viruses, no statistically significant difference was found in sex, age, clinical type, laboratory examination, or whether repositive (P>0.05), but there was statistically significant difference in the distribution of domestic and imported cases (P=0.016). Type B virus infected patients were mostly domestic cases, while type B.X virus infected patients were mostly imported cases. Conclusion The distribution of domestic and imported cases is different among SARS-CoV-2 of different genotypes.
Objective To investigate the effects of noninvasive ventilation for the treatment of acute respiratory failure secondary to severe acute respiratory syndrome ( SARS) . Methods 127 patients with complete information were collected from the database of SARS in Guangdong province, who were all consistent with the ALI/ARDS diagnostic criteria. The patients were divided into three groups depending on ventilation status, ie. a no-ventilation group, a noninvasive ventilation group, and a mechanical ventilation group. The outcome of ventilation treatmentwas followed up.Multi-factor regression analysis was conducted to analyze the relations of ventilation treatment with ARDS and mortality, and factors associated with success of noninvasive ventilation. Results As soon as the patients met the diagnostic criteria of ALI/ARDS, the patients in the noninvasive ventilation group were in more serious condition and had a higher proportion of ARDS compared with the no-ventilation group ( P lt;0. 01) . The patients in the mechanical ventilation group had a higher mortality rate ( P lt;0.01) . 6 and 7 patients in the no-ventilation group had noninvasive ventilation and invasive ventilation thereafter, respectively. 15 patients in the noninvasive group switched to invasive ventilation. Compared with the patients without ventilation ( n =45) , the patients receiving noninvasive ventilation ( n = 61) were in more serious condition and at higher risk of developing ARDS ( P lt;0. 01) , but the mortality was not different between them ( P gt; 0. 05) . The patients who continued to receive noninvasive ventilation ( n = 40) were in more serious condition, and at higher risk of developing ARDS compared with the patients without ventilation ( n = 45) ( P lt; 0. 01) . 15 patients in the noninvasive group who switched to invasive ventilation were older than those patients continuing noninvasive ventilation.Conclusions For SARS patients fulfilling the ALI/ARDS criteria, the patients underwent noninvasive ventilation are more severe, run a higher probability of developing ARDS from ALI. But earlier initiation of noninvasive ventilation has no impact on mortality. The patients who tolerate noninvasive ventilation can avoid intubation, especially for young patients. However, the time and indication of shifting from noninvasive ventilation to invasive ventilation should be emphasized.
