中学生物学教学中渗透生理急救教育的研究

中学时期是事故发生的高频年龄段,开展生理急救教育是避免事故伤害的有效保障措施。当代中学生生理急救知识缺乏,生理急救技能不足,突发事件面前,心理素质不好,法律知识缺乏。要解决这些问题,就要在课堂中渗透生理急救知识、课外实践活动中进行生理急救技能训练、培养学生生理急救心理素质,增强学生生理急救法律知识。

Life-threatening Spontaneous Retroperitoneal Haemorrhage:Role of Multidetector CT-angiography for the Emergency Management

Objective To evaluate the role of multidetector computed tomography-angiography(MDCTA) for management of life-threatening spontaneous retroperitoneal haemorrhage(SRH).Methods A retrospective analysis of the medical records of all SRH patients admitted to our hospital from January 1,2005 to November 31,2014 was performed.SRH was defined as unrelated to invasive procedures,surgery,trauma,abdominal tumor or aortic aneurysm.Life-threatening SRH was defined as hemodynamic instability with hypotension.Sixteen cases met the inclusive criteria.Patients' characteristics,clinical presentation,imaging of MDCTA,treatment modalities,morbidity,and follow-up data were analyzed.Results The group of 16 patients included 11 men and 5 women,with a mean age of 51.5 ± 16.4years.All patients underwent MDCTA scan examinations,and active contrast media(CM) extravasation were found in 9 patients.Angiography was performed for 8 patients in the CM extravasation group.Bleeding vessels were found in 7 patients who underwent successful embolization.One patient in the CM extravasation group did not undergo angiography and died of bleeding.Seven patients without active CM extravasation underwent conservative management.Bleeding was controlled for all these 7 patients,and 1 patient died of multiple organ failure.Fourteen patients survived from SRH were successfully discharged.One patient died of heart failure during follow-up.Conclusion MDCTA was useful in the diagnosis of SRH and proved to be predictive for the outcome of conservative treatment and early intervention.

Collaboration mechanism of intercity emergency rescue ecosystem

With the development of metropolitan regions and the appearance of urban agglomerations, cities have been more closely related. For the restricted emergency rescue resource in a single city, it has become more and more imminent for the demand of the intercity collaborative resistance to major accident, so as to improve the protection capacity of urban security. In order to find an effective intercity, emergency rescue collaborative system, this paper introduces the concept and analysis method of ecosystem theory into intercity emergency, rescue. Based on the analysis of the formation-process of emergency rescue individual, population and community： a throe-level intercity emergency rescue collaborative system is constructed according to the characteristics of dynamics and structure of intercity emergency rescue ecosystem then the collaboration mechanism of information, resource and process in the interceity emergency rescue ecosystem is also studied in this paper; so as to offer available strategy and method for the ecosystem theory applied to intercity, emergency rescue. Through the studies of intereity emergency rescue ecosystem. it illuminates that the proposed emergency system can not Only cope with the major accident more timely and effectively but also integrate the intercity information resources and emergency rescue resource and process optimization.

在实践中普及中学生急救知识

中学时期是事故发生的高频年龄段,开展生理急救教育是避免事故伤害的有效保障措施。当代中学生生理急救知识缺乏,在生理急救方面技术能力有所不足,当遇到突发事件时,心理素质比较低下,而且还缺乏法律保护意识。要解决这些问题,就要在课堂中加入生理急救知识、课外实践活动中进行生理急救技能训练、培养学生生理急救心理素质,增强学生生理急救法律知识。全社会需要关注中学生急救知识的推广和普及。
