ABSTRACT Introduction: The mass reception of intoxicated people in hospitals, resulting from chemical emergencies, is based on general theoretical postulates of chemical emergencies, mass casualty events and systems theory, which must contribute to the disaster risk reduction. Objective: To design a hospital theoretical conception for mass reception of intoxicated people resulting from chemical emergencies. This conception should contribute to the response phases of the disaster risk reduction. Methods: This is a research on health systems and services conducted from 2005 to 2017. We reviewed and analyzed bibliometric and infometric sources and we consulted experts. To determine the relevance, we focused on the process of result concretion and consensus method. Results: The mass reception of intoxicated patients in hospitals was conceived as a system of four subsystems. The basic are preparatory, executive and recuperative subsystems. The assurance subsystem guarantees the operation. All subsystems relate to each other with significant dependence between them. This system is flexible, objective, participatory, timely, acceptable, adequate and selective. Conclusions: The systemic approach of the mass reception of intoxicated patients in hospitals resulting from chemical emergencies constitutes a valuable theoretical reference for its basic comprehension as a complex phenomenon. Four subsystems structures it: preparatory, executive, recuperative and assurance. It contributes to the response phases of the cycle for disaster risk reduction(AU)

Single Center Experiences to Landslides on Woo-myun Mountain: Preparedness, Response, and Lessons Learned

PURPOSE: On July 27, 2011, landslides occurred on Woomyun Mountain, resulting in development of mass casualties. Seoul St. Mary's Hospital was the primary recipient of patients. This experience prompted the drafting of a formal disaster plan. Therefore, we outline the Emergency Management External Disaster Plan of Seoul St. Mary's Hospital and discuss the time course of presentation and medical characteristics of the patients. METHODS: We conducted a retrospective review of medical records of patients who visited Seoul St. Mary's Hospital from Woo-myun Mountain landslides. In addition, we reviewed the time course of hospital disaster response. RESULTS: A total of 33 patients participated in this study. Mean age was 40.2 (+/-21.8) years; eight patients died at the time of admission and cardiopulmonary resuscitation was performed in one patient. Mean Injury Severity Score (ISS) was 9.19 and four patients were ISS above 15. Six patients were admitted to our hospital and two patients underwent an emergency operation. Overall, the emergency disaster management was appropriate due to the formal disaster plan and experiences in conduct of disaster drills. However, there were also several problems. The major problems of our disaster response were as follows: delayed activation of external disaster, difficulties in securing a treatment section, and absence of a decontamination facility. CONCLUSION: We observed several problems from our experience with Woo-myun Mountain landslides. Reassessment of the disaster plan and additional planning for other possibilities are needed.

Atendimento pré-hospitalar à múltiplas vítimas com trauma simulado / Prehospital care to trauma victmis with multiple simulated

OBJETIVO: Analisar a qualidade do atendimento pré-hospitalar realizado pelas agências em Vitória-ES. MÉTODOS: Estudo retrospectivo realizado nos arquivos da Liga Acadêmica de Cirurgia e Atendimento ao Trauma do Espírito Santo (Lacates) dos dados de 40 vítimas de um acidente simulado entre um ônibus e dois automóveis. Os pacientes foram assistidos por quatro equipes: Corpo de Bombeiro Militar do Espírito Santo, Samu 192, Guarda Municipal e Defesa Civil. A atuação dessas equipes foi avaliada pela Lacates, através da análise do check-list com orientações pré-estabelecidas para cada vítima. RESULTADO: O Corpo de Bombeiros Militar do Espírito Santo (CBMES), que desencarcerou as vítimas, delimitou as zonas de perigo e realizou a triagem pelo método START atuou corretamente em 92,5% dos casos. O Samu 192 que atendeu as vítimas pelo método mnemônico (ABCDE) no posto médico avançado agiu corretamente em 92,5% dos casos, no quesito Via Aérea; 97,5%, no Respiração; 92,5%, no Circulação; 90%, no Avaliação Neurológica; e 50%, no Exposição e Controle do Ambiente. A análise conjunta do ABCDE mostrou que o atendimento foi correto em 42,5% dos casos. O transporte dos pacientes foi realizado corretamente em 95% dos casos. A Guarda Municipal garantiu a perviedade das avenidas para transporte dos pacientes, e a Defesa Civil coordenou eficazmente o trabalho das equipes envolvidas no posto de comando. CONCLUSÃO: A triagem e o transporte foram executados satisfatoriamente, entretanto, maior atenção deve ser dada à exposição e proteção contra hipotermia das vítimas, já que esse item comprometeu o tratamento.

OBJECTIVE: To assess the quality of prehospital care agencies conducted in Vitória, capital of Espírito Santo State, Brazil. METHODS: We conducted a retrospective study in the archives of the League of Academic Surgery and Trauma Care of Espírito Santo (Lacates) regarding 40 victims of a simulated crash between a bus and two cars. The patients were treated by four teams: Military Fire Department of Espírito Santo, Samu 192, County Guard and Civil Defense. The performance of these teams was evaluated by Lacates, through analysis of a check-list with pre-established guidelines for each victim. RESULT: The Fire Department of Espírito Santo (CBMES), which extricated victims, outlined the danger zones and carried out the screening by the method START, acted correctly in 92.5% of cases. The Samu 192 victims, which attended victims by the mnemonic method (ABCDE) in medical outposts, acted correctly in 92.5% of cases in the category Airway; 97.5% in breathing, 92.5% in circulation, 90% in Neurological Assessment, and 50% in the Exhibition and Environmental Control. The analysis showed that the ABCDE care was correct in 42.5% of cases. The transport of patients was performed correctly in 95% of cases. The County Guard secured the patency of the avenues for transportation of patients and Civil Defense successfully coordinated the work of teams involved in the command post. CONCLUSION: The triage and transport of victims have been performed satisfactorily. However, more attention should be given to exposure and hypothermia protection of victims, since this item compromised treatment.

Successful experiences in treating thirty-five burned victims in a single batch transferred from a remote area / 解放军医学杂志

Objective To introduce the successful experiences in treating 35 burned victims transferred from a remote area.Methods Thirty-five burned casualties were transferred to our burns institute from a remote area on the post-burn day 2,May 28,2006.All of them were males,age ranged from 17 to 46 years with mean of 22.4?8.7 years.The mean total burned area was 13.6%?12.9% TBSA(ranged from 4% to 75%).Among them,32 patients also manifested the signs of severe inhalation injury.In all of the patients,heart function,pulmonary function,liver function,renal function,and coagulation function were abnormal.Therefore,they were in critical condition with multiple complications,demanding most meticulous care.On this occasion,our strategies consisted of dispatching experienced surgeons and nurses to the referring hospitals and the airport to accept the patients to give appropriate care to them during the journey.The medical staff was well organized to insure that each of them was ordained specific duty.The conditions of patients were evaluated immediately and appropriate treatment was expeditiously started to arrest those lethal complications on arrival.Timely and exact comprehensive treatments were prerequisite to save the patients' life.Adequate metabolic support should be emphasized,and either coagulant or anticoagulant treatment should be given when indicated.Results All of the patients survived.Conclusion In dealing with mass burn casualties,organizational work is essential to prevent any untoward complications during the transportation,and the staff of the receiving hospital sheald also be organized to treat any life-threatening conditions on arrival of the palients.Meticulous care should be given to all the patients,and fatal complications are expeditionsly treated in order to achieve a satisfactory result.

Successful treatment for multiple patients with severe burn injury complicated by inhalation injury / 解放军医学杂志

Objective To study the emergency treatment,diagnosis and integrative treatment for the patients with severe burn injury combined with inhalation injury.Methods Thirty-five burn victims in a mass casualty were airlifted to our Burns Institute from a remote area on second day post-burn,including 14 patients who had received emergent tracheostomy for inhalation injury.After hospitalization,bronchoscopic examinations were done for further evaluating the inhalation injury,and timely locating and removing of sputum crust and necrotic mucosa from the airway in patients with signs of dyspnea,and helping decide the opportune time of removing the tracheostomy tube.The "artificial nose" and intratracheal instillation and lavage were used for humidifying the mucosa of the tracheobronchial tree.The stryker frame,vibrator and expectorant were also used to facilitate expectoration.Epidermis growth factor was topically used for promoting the restoration of the injured endotracheal mucosa.Results The degree of inhalation injury in fourteen patients with tracheostomy was identified through bronchoscopy as moderate(3 cases),severe(8 cases),and very severe(3 cases).The tracheostomy tubes were removed within one week in seven patients(50.0%),and during the second week post-burn in six patients(43%).The removal of tube was delayed in the remaining patients until 42nd day post-burn because of multiple organ dysfunction syndrome.Pulmonary infection occurred in two patients on the 10th day post-burn,and pathogens were found in tracheo-bronchial discharge in three patients.Conclusion Emergent tracheostomy should be performed the earlier the better for severe inhalation injury,and bronchoscopy was desirable for distinct diagnosis and treatment,especially for estimating the repair of tracheal mucosa and deciding the time for removal of the tracheostomy tube.Moistening the tracheo-bronchial tree through instillation of fluid with drugs and "artificial nose",and the use of Stryker frame,vibrator and expectorant were effective in facilitating expectoration and preventing lung infection.Topical use of epidermis growth factor may be helpful for the repair of injured tracheal mucosa.

Organization of long-distance transportation of thirty-five burned victims in a single batch-a summary of successful experiences / 解放军医学杂志

Objective To sum up the experiences of successful long-distance transportation of 35 burned casualties as a result of a mass fire catastrophe.Methods Thirty-five burned victims of a mass fire catastrophe were transported by air from a northern part of Heilongjiang province to Beijing,a voyage of 1600km.The successful experiences of organization and medical instructions during the transportation were summed up and analyzed.Results The transportation was launched 20 hrs after the arrival of specialists group.Under a well-knitted organization and meticulous care,all the casualties were transported to the destination safely and smoothly in 4 hrs.Conclusions Before transportation the condition of the patients to be transported and their tolerance to the ordeal of transportation must be evaluated or judged according to the general condition of each patient,and due precaution should be carefully taken.Medical staff,drugs and equipments for circulatory and respiratory care must be provided for immediate care of any life-threatening complications which might occur during the air-lift and road transportation.Before transportation tracheostomy tube and venous line should be secured,especially for those with head and face burns,the airway must be kept free.The patients were tagged with number and with their conditions documented on wound tags to ensure the patients to receive prompt and proper care in accordance to their condition in the accepting hospital.During airlift,the stretchers should be arranged close to the exit of the plane and perpendicular to the longitudinal axis of the cabin.Ample space should be kept between stretchers to allow emergent care.The hospital of destination must check the wound tags carefully and try its best to treat the patients as earlier as possible.All these efforts were contributory to successful transportation of these mass burn casualties.

Early repair and reconstruction for the wounds of face and joints of mass burn casualties / 解放军医学杂志

Objective To repair and reconstruct severe burn wounds on face,hands and joints with the principles and techniques of plastic and aesthetic surgery.Methods Twenty three burn victims in a single batch were transferred from a remote area to our Burns Institute on post burn day 2,June 28,2006.All the patients were males aged from 17 to 46 years,with a mean of 24.4?6.3 years,the mean total burn area was 15.7%?13.9% TBSA(ranged from 6% to 75%),with moderate to severe inhalation injury,and fourteen of them had received tracheostomy.The burn areas on face ranged from 0.5% to 3% TBSA,and all of them were deep second or third degree burn.The burn areas on hands ranged from 1% to 4% TBSA of deep second or third degree.On post burn day 3,the patients received escharectomy or tangential excision of eschar on hands followed by split thickness skin grafting with the principles and techniques of plastic and aesthetic surgery.During post burn week 2 to 3,the eschar on the faces were peeled off,followed by split-thickness skin grafting according to the principles and techniques of plastic and aesthetic surgery.Results All the wounds on the face and joints were repaired successfully,the configuration and functions were satisfactory.Conclusion It is feasible to repair the burn wounds on face and joints with the principles and techniques of plastic and aesthetic surgery for the burn patients of mass fire catastrophe.

A Study on the Method of Description for Mass Casualties Based on Abbreviated Injury Scale and Injury Severity Score / 대한정형외과학회잡지

With the industrial development, vehicle, wars, and natural disasters, there are increasing chsnces of mass casuaities, it is very important to classify the injured patients by their severity, to give them immediate emergency care and to transfer them to the other medical facilities effectively. And it is more essential in the army. But in practice, there is no objective and comprehensive scale for injury severity yet. So we devised a method of comprehensive description for the injuredpatients. It is based on Abbreviated Injury Scale and Injury Severity Score and is composed of five parts of the body (General, Head & Neck, Chest, Abdomen, Extremities) and five degrees of severity (Grade I, Il, III, IV, V). For example, a description of a patient with multiple injuries such as generalized abrasion and cotusion, semicomatose mentality with skull fracture, hemoperitoneum, and fracture of right femoral shaft is very diffcult to understand quickly. But, with our method of description, the above is described as follows ; G(I)+(IV)+A (IV)+E(III), ISS =4+4+3 =41. And the high score is described as ISS makes it clear that the patient is very dangerous, even to death, so intensive care is immediately needed. Using this method, we reviewed 1,256 cases of passenger acidents of vehicles treated at our hospital during the last 2 years. The results were as follows ;1. The average ISS of 56 cases of dead is 33. 2. There are only 2 cases of death below 16 of ISS, and 84% mortality above 40 of ISS. 3. The average ISS of passengers in vehicles such as motocycles is 12, taxies 11, bongo 9, and buses 8. 4. We recommend our method of description for mass casualties, especially in the army. Because it is very useful to the injured patients by their severity, to give them immediate emergency care, to transfer them to the other medical facilities and to comprehend the whole condition of all patients.
