ABSTRACT
Vascular injury is common in war and is mainly caused by explosion and other causes. It is the key cause for the increase of war casualties. The incidence of vascular injury is the highest in extremities, followed by neck, pelvis, chest and abdomen, and arterial injury is more than venous injury. The animal model of vascular injury is an animal model used in military medical research. It can simulate vascular trauma on the battlefield, and is essential to reduce the battlefield casualties caused by vascular injury. At present, there are two kinds of animal models of vascular injury used in clinical research, including traumatic vascular disease model and traumatic bleeding model. Rabbits, murine and pigs are the common experimental animals for the animal models of vascular injury. In this review, we sum up the recent research advances, future development and difficulties of animal models of vascular injury.
ABSTRACT
The application of four kinds of hemostatic tools in tactical combat casualty care (TCCC) of foreign armies was introduced,including extremity tourniquet,junctional tourniquet,hemostatic dressing.and elastic bandage as well as tranexamic acid.The above hemostatic tools were described from the aspects of structure,operating process,application range and technical points,and the histories of some tourniquet were also expounded.The problems of Chinese PLA were analyzed in designing and developing hemostatic tool.Some suggestions were put forward such as enhancing the practicability and portability of hemostatic tool,rational allocation of TCCC drugs and instruments and etc.
ABSTRACT
Objective To develop a portable jet-flow device for preliminary debridement of wound mainly in battlefield,which can also be used for the treatment of nuclear or chemical weapon injury at wartime and peacetime.Methods The device was composed of a dynamic system,a servo system and consumable accessories,and developed based on a pneumaticpower scheme.Composite power unit free of dependence on electric power transferred the pneumatic power to three kinds of disinfectants through the four-way pipes.Results The device with easy operation consumed a few disinfectant and completed debridement within 30 minutes,with infection avoided effectively.Conclusion The device gains advantages in low weight,compact structure,function and low cost,and can be used for early debridement in field conditions.
ABSTRACT
Objective To develop a portable pressure detector to facilitate the battlefield self and buddy aids training for dressing,hemostasis and fixation.Methods The changes of pressure were converted into the ones of electric current with the pneumatic cuff,catheter and membrane pressure sensor,and then transmitted to the panel display by Bluetooth.The efficacy for the training was determined based on the acquired data.Results The detector implemented quantifying of the pressures during dressing,hemostasis and fixation,and non-medical staff obtained the results of battlefield treatment training easily to execute rapid assessment of battlefield self and buddy aids training.Conclusion The device gains advantages in visualized data,portability,easy operation and accurate measurement,and contributes to battlefield self and buddy aids training.
ABSTRACT
Objective To establish a comprehensive war injury care and treatment capcity evaluation index system. Methods The Delphi method was used for establishing the evaluation index system and the analytic hierarchy process was used for the calculation of the index weight.Finally,the fuzzy comprehensive evaluation method was used to test the effectiveness of the index system.Results The evaluation model was formulated with 4 dimensions and 16 indicators,which provided reference for the evaluation of war injury care and treatment capacity in field medical facilities.Conclusion The result shows that this evaluation index system is characterized by high credibility and sensitivity,which can satisfy the need of war injury care and treatment capcity evaluation in field medical facilities.
ABSTRACT
Objective To explore the effect of newly developed XSTAT 30 hemostatic apparatus for US army TCCC. Methods The characteristics and application effects of XSTAT 30 were described from the aspects of design, indication and contraindication, operation and precautions, application safety and etc. Results In tactical echelons XSTAT 30 could be used for the hemostasis of penetrating fragment injuries at groin, armpit and etc. Conclusion XSTAT 30 behaves well in the hemostasis at the junction sites, and is worthy referencing for designing likely devices of the PLA.
ABSTRACT
BACKGROUND: wars and its challenges have historically afflicted humanity. In Syria, severe injuries occurred due to firearms and explosives used in the war between government forces and civilians for a period of over 2 years. MATERIALS AND METHODS: the study included 364 cases, who were admitted to Mustafa Kemal University Hospital, Medicine School (Hatay, Turkey), and underwent surgery. Survivors and non-survivors were compared regarding injury site, injury type and number of transfusions given. The mortality rate found in this study was also compared to those reported in other civil wars. RESULTS: the mean age was 29 (3-68) years. Major sites of injury included extremities (56.0%), head (20.1%), abdomen (16.2%), vascular structures (4.4%) and thorax (3.3%). Injury types included firearm injury (64.4%), blast injury (34.4%) and miscellaneous injuries (1.2%). Survival rate was 89.6% while mortality rate was 10.4%. A significant difference was observed between mortality rates in this study and those reported for the Bosnia and Lebanon civil wars; and the difference became extremely prominent when compared to mortality rates reported for Vietnam and Afghanistan civil wars. CONCLUSION: among injuries related to war, the highest rate of mortality was observed in head-neck, abdomen and vascular injuries. We believe that the higher mortality rate in the Syrian Civil War, compared to the Bosnia, Vietnam, Lebanon and Afghanistan wars, is due to seeing civilians as a direct target during war.
JUSTIFICATIVA: Historicamente, as guerras e seus desafios afligem a humanidade. Na Síria, lesões graves ocorreram devido às armas de fogo e explosivos usados na guerra entre as forças governamentais e civis durante um período de mais de dois anos. MATERIAIS E MÉTODOS: O estudo incluiu 364 pacientes, admitidos no Hospital da Universidade Mustafa Kemal da Faculdade de Medicina (Hatay, Turquia) e submetidos à cirurgia. Os sobreviventes e não sobreviventes foram comparados quanto ao local e tipo da lesão e número de transfusões administradas. A taxa de mortalidade encontrada neste estudo também foi comparada àquelas relatadas em outras guerras civis. RESULTADOS: A média de idade foi de 29 (3-68) anos. Os principais locais de lesão incluíram extremidades (56,0%), cabeça (20,1%), abdome (16,2%), estruturas vasculares (4,4%) e tórax (3,3%). Os tipos de lesões incluíram ferimento de arma de fogo (64,4%), lesão causada por explosão (34,4%) e ferimentos diversos (1,2%). A taxa de sobrevivência foi de 89,6%, enquanto a taxa de mortalidade foi de 10,4%. Observou-se uma diferença significativa entre as taxas de mortalidade neste estudo e aquelas relatadas para as guerras civis da Bósnia e Líbano; e a diferença ficou extremamente significativa quando comparada com as taxas de mortalidade relatadas para as guerras civis do Vietnã e do Afeganistão. CONCLUSÃO: Dentre as lesões relacionadas à guerra, a maior taxa de mortalidade foi observada em lesões de cabeça-pescoço, abdome e vasculares. Acreditamos que a maior taxa de mortalidade na Guerra Civil da Síria, em comparação com as guerras da Bósnia, Vietnã, Líbano Afeganistão, se deva ao fato de os civis terem sido vistos como alvo direto durante a guerra.

Field medical equipment is important material base of medical service in wartime and one organic part of medical care scheme in echelon. However, medical service under hot and humid environment (HHE) is characterized by some new features due to the dual influences of environmental factor and war injury itself, which might bring certain challengeable demands on medical equipment development. As one part of medical care scheme in echelon under HHE, this paper presents a general study on demands of field medical equipment under HHE aimed to provide references for demonstration, research and development of medical equipment of Chinese PLA in the future.
