Application of multidisciplinary team (MDT) in the treatment of severe trauma / 北京大学学报(医学版)

OBJECTIVE@#To explore the effect of multi-disciplinary team (MDT) in general hospitals on severe trauma patients.@*METHODS@#This study reviewed the treatment of patients with severe trauma in trauma center of Peking University People's Hospital from March 2017 to April 2019. The baseline information: the patients' gender, age, injury mechanism, etc.; the start indicators: the Glasgow coma scale (GCS), trauma index (TI), injury severity score (ISS); the start related indicators: time for activation, time for MDT to arrive, time for CT scan, time for damage control surgery; patient treatment and prognosis: ICU (intensive care unit) length of stay, number of cured and discharged patients, number of dead cases, number of patients transferred to rehabilitation hospital, were all analyzed. It discussed the composition of MDT, the initiation scheme, the indicators of initiation of MDT for severe trauma, and analyzed the correlation between the application of MDT and the prognosis of patients.@*RESULTS@#From March 2017 to April 2019, 112 trauma patients were treated by MDT in Peking University People's Hospital. There were 69 males and 43 females. The minimum age was 15 years, the maximum age was 89 years, most of them were 36-55 years old. The main injury mechanism was traffic accident injury. The GCS, TI, ISS were 13.0±2.9, 13.0±2.8, and 21.5±11.9, respectively. It took 3.7±0.8 minutes to start the call, 6.1±0.9 minutes for MDT personnel to arrive at the emergency rescue area, 23.8±3.0 minutes for fast CT and 92.6±15.4 minutes for injury control operation. All the hospitalized patients were treated effectively. ICU (Intensive care unit) hospitalization time was 12.6±6.7 days. 55 discharged patients were cured, 5 died (1 died of hemorrhagic shock, 4 died of severe brain injury) and 52 transferred to rehabilitation hospital.@*CONCLUSION@#The treatment of severe trauma patients by MDT in trauma center of general hospitals can greatly improve the ability and level of treatment of severe trauma patients, make up for the lack of treatment of severe trauma especially multiple trauma patients in large general hospitals, and improve the treatment effect of severe trauma patients. It provides a reference model for large general hospitals to treat patients with severe trauma and multiple trauma and for the construction of trauma centers.

Meta-analysis on tetanus antibody protection rate of healthy population born after 1978 in China / 中华预防医学杂志

Meta-analysis was conducted on the tetanus antibody protection rate of healthy population born after 1978 in China (data from Hong Kong, Macao and Taiwan was excluded, the same below). Search the data on China's tetanus antibody level which were published in China National Knowledge Infrastructure, Wanfang data, VIP, SinoMed database, PubMed and the Cochrane Library. The Chinese search keywords were "Tetanus Antitoxin", "Tetanus Antibody", "Healthy Population" and "Mainland China". English search terms include "tetanus antitoxin", "tetanus vaccine", "tetanus vaccine", "general population" and "mainland of China". The time limit for inclusion in literature research was 2010-2019. Stata software was used to conduct meta-analysis on the protection rate of tetanus antibody. A total of 24 articles were included. There was no obvious publication bias in the included articles. The total number of respondents was 23 530, the antibody protection rate was 49.5%-99.0%. A total of 20 817 people got effective antibody protection, which meant the antibody level reached and exceeded 0.1 IU/ml, and the combined protection rate was 78.6% (95: 75.0%-88.2%). The combined protection rates of antibody in 0-7 years old and 8-15 years old groups were 88.9% (95: 86.9%-91.0%) and 79.3% (95: 72.9%-86.2%) respectively. The combined protection rates of antibodies in 16-20 years old, 21-30 years old and 31-40 years old groups were 58.9% (95: 46.5%-71.2%), 47.7% (95: 16.8%-78.7%) and 63.8% (95:32.6%-95.1%) respectively. The combined protection rate of tetanus antibody for 0-15 years old people was 85.6% (95: 83.1%-88.1%), and the combined protection rate of antibody for 16-40 years old people was 52.9% (95: 39.3%-66.6%). With the increase of age, the protection rate of tetanus antibody among the healthy population aged 16-40 years in our country decreases. An individualized vaccination plan should be formulated according to the previous tetanus vaccination history and the tetanus antibody level when necessary.

Research progress of tetanus antibody detection technology in China / 中华预防医学杂志

The situation of prevention of non-neonatal tetanus in China is severe. Strengthening the active immunization with tetanus toxoid vaccine (TTCV) is the key to prevent the non-neonatal tetanus. Through the detection of tetanus antibody (TAB), the immune status of individual can be determined, so as to implement the active immunization of TTCV correctly. The research on TAB detection technology is stagnant in aboard, but still in a development process in China since there is a realistic demand for TAB detection. This review collects relatively limited data of TAB detection technology in China, and summarizes the techniques such as mice toxin neutralization test (MTNT), indirect hemagglutination assay (IHA), double agar gel immune diffusion test (Rubin method), enzyme-linked immunosorbent assay (ELISA) and colloidal gold (CG), in order to provide a comprehensive basis for domestic TAB detection. The TAB detection technology in China has not yet achieved international recognition due to the lack of comparative study of domestic and international institutions and reference reagents. The special domestic situation of tetanus prevention makes the research of TAB detection technology have a certain practical significance, and rapid detection reagents such as ELISA and CG method have a certain application value in China.
