Herein, we look to further a discussion on upper and lower limb reconstruction following MCIs.Methods: Review of the literature, including our institute's experience with the 2013 Boston Marathon Bombings, the 2015-2016 Terror Attacks in Ankara, and the 2010 earthquake in Haiti, pertaining to extremity reconstruction following MCIs.Results: The three aforementioned case profiles highlight extremity wounds associated with MCIs and the subsequent reconstructive role of plastic surgeons. Surgical intervention or temporization of extremity wounds is a critical responsibility of plastic surgeons in this setting. Limb salvage is possible and often the preferred option following disasters.Conclusion: Intentional or naturally occurring MCIs are a grim reality. Successful response to these events requires prompt mobilization of emergency medical staff and hospital activation. Plastic surgeons play a paramount role in multidisciplinary management of trauma with a particularly important involvement in limb reconstruction.展开更多

Triage systems originate from wartime necessity to achieve the greatest efficiency to the maximum number of victims. In peacetime, the triage systems are applied to allocate constrained medical resources for the victims in MCI. There are several kinds of triage systems in different countries, such as Simple Triage and Rapid Treatment (START), Sort, Assess, Life-saving interventions, Treatment and/or Transport (SALT), Sacco Triage Method (STM), Careflight triage and Triage Sieve (TS). The START system is widely used in developed countries, especially in USA. The SALT is formulated by a work group of the Centers for Disease Control and Prevention (CDC) based on scientific data. STM is a triage algorithm designed for resource-constrained condition. Besides, the other triage systems show their power in managing the victims in MCI. However, the data of theses popular triage tools are mainly based on simulated tests, lacking of validity and reliability of triage systems. Therefore, the application, reliability, sensitivity and specificity of existing triage tools require to be validated in the real condition of MCI. Furthermore, due to the difference among triage tools used in different countries, international cooperation is demanded for a more highly organized mass-casualty medical response.展开更多

Methods： We searched PubMed, EMBASE China Wanfang, and China Biology Medicine （CBM） databases for relevant studies. The following key words and medical subject headings were used： ＇mass casualty incident＇, ＇MCI＇, ＇research method＇, ＇Wenchuan＇, ＇earthquake＇, ＇research paradigm＇, ＇science of surge＇, ＇surge＇, ＇surge capacity＇, and ＇vulnerability＇. Searches were performed without year or language restriction. After searching the four literature databases using the above listed key words and medical subject headings, related articles containing research paradigms of MCI, 2008 Wenchuan earthquake, July 5 bus fire, and science of surge and vulnerability were independently included by two authors. Results： The current progresses on MCI management include new golden hour, damage control philosophy, chain of survival, and three links theory. In addition, there are three evaluation methods （medical severity index （MSI）, potential injury creating event （PICE） classification, and disaster severity scale （DSS））, which can dynamically assess the MCI situations and decisions for MCI responses and can be made based on the results of such evaluations. However, the three methods only offer a retrospective evaluation of MCI and thus fail to develop a real-time assessment of MCI responses. Therefore, they cannot be used as practical guidance for decision-making during MCI. Although the theory of surge science has made great improvements, we found that a very important factor has been ignored--vulnerability, based on reflecting on the MCI response to the 2008 Wenchuan earthquake and July 5 bus fire in Hangzhou. Conclusions： This new paradigm breaks through the limitation of traditional research paradigms and will contribute to the development of a methodology for disaster research.展开更多

Methods： Data were extracted from the Army Staff Headquarters based on daily reports of Iranian army units during the war. Results： During 52 days, Tehran was stroked by 118 A1-Hussein missiles （a modified version of Scud missile）. Eighty-six missiles landed in populated areas. During Iraqi missile attacks, 422 civilians died and 1 579 injured （4.9 deaths and 18.3 injuries per missile）. During 52 days, 8.1 of the civilians died and 30.4 injured daily. Of the cases that died, 101 persons （24%） were excluded due to the lack of information. Among the remainders, 179 （55.8%） were maleand 142 （44.2%） were female. The mean age of the victims was 25.3 years＋19.9 years. Our results show that the high accuracy of modified Scud missiles landed in crowded areas is the major cause of high mortality in Tehran. The presence of suitable warning system and shelters could reduce civilian casualties. Conclusion： The awareness and readiness of civilian defense forces, rescue services and all medical facilities for dealing with mass casualties caused by ballistic missile at- tacks are necessary.展开更多
