During the course, we carried out a retrospective analysis about clinical data and the course of diagnose and treatment of 38 patients (65 cases) with myasthenia gravis crisis who were in hospital in recent 15 years. As a result, most patients with myasthenia gravis crisis relieved after positive treatment and the mortality was 3.1%. Among lots of treatments, incision of trachea earlier, hormonal therapy, dry treatment and to unite these three treatments were more effective than other treatments. The effective ratio was 100%. In the end, we concluded that to unite incision of trachea, immunosuppressive treatment and dry treatment reasonably can increase the effective ratio of rescuing myasthenia gravis crisis and improve the prognosis of patients obviously.展开更多

Methods: according to the random drawing method, 80 patients with organophosphorus and organophosphorus pesticide poisoning admitted to our hospital from May 2020 to April 2021 were selected and divided into analysis group and control group, which received interventional treatment and rescue treatment respectively. The intervention was carried out by conventional nursing methods in this group, and the nursing satisfaction rate of patients was compared with the rescue nursing effect of the control group and the analysis group. Results: the nursing satisfaction rate of patients in the analysis group who received rescue related treatment was significantly higher than that in the control group who received routine nursing measures, while the rescue treatment score of patients in the control group was significantly lower than the effectiveness score. There was clinical correlation between the two groups (P < 0.05). The incidence of adverse reactions in the analysis group was better than that in the control group, and the difference between the two groups was clinically comparable (P < 0.05). Conclusion: gastric lavage has a significant effect on patients with organophosphorus pesticide poisoning. It can effectively improve the success rate of rescue and the satisfaction of patients' nursing, and strive for rescue time to the greatest extent, which is unanimously recognized by the families of the patients.展开更多

Climate-induced impacts and threats in mountainous tourism areas are more challenging given complex terrains and multiple risk sources. Prior studies have focused on assessing climate-related impacts in mountainous tourism areas, while limited studies have investigated the emergency rescue capacity of mountainous tourism areas. This largely constrains decision makers to adopt proper solutions to enhance emergency rescue capacity. To address this research challenges, this study aims to assess emergency rescue capability through an empirical study of the Wulong Karst Tourism Destination(WKTD) area in Chongqing, China. In particular, based on road network and emergency response facility data, the accessibility of road network was delineated by the Spatial Design Network Analysis(s DNA) model. The results indicate that fire and medical rescue facilities were extremely limited and their service coverage was irregular. Valleys significantly narrowed rescue facilities' service area and weakened their functional connection. With the vital 60-minute timeframe, the closeness and betweenness analyses revealed the low accessibility of global rescue roads, while relatively high accessibility of small-scale vehicle and pedestrian rescue roads. The Mean Crow Flight(MCF) and Diversion Ratio(DR) analyses verified that the accessibility of road rescue services was impeded by mountainous terrain. Overall, this study informs solutions pertaining to rescue and disaster mitigation in mountainous tourism areas.展开更多
