Pre-hospital interventions : introduction to life support systems

Crucial decisions in pre-hospital emergency care are often made; therefore, a tactical emergency medical support team (TEMS) should maintain the capacity to capture the situation instantaneously and in all circumstances. However, low exposure to severe trauma cases can be a weakness for emergency specialists, which makes pre-hospital assessment more difficult. Pre-hospital interventions (PHI) are usually classified in Western countries into BLS (basic life support) and ALS (advanced life support) levels, according to the methods used. This review introduces tactical combat casualty care for medical personnel (TCCC) guidelines, designed for basic care management under fire or in a hostile environment. The phases of TCCC are: (1) care under fire (or in an unstable environment); (2) tactical field care; and (3) tactical evacuation care, and are mainly dependent on the different hazard zones (hot, warm or cold). In a mass casualty situation due to disaster or cataclysm, standardized protocol and triage are unquestionably required for identifying the environmental risks, for categorizing the casualties in accordance with medical care priorities, and for the initial management of casualty care. When considering conflict situations, or chemical, biological, radiological, or nuclear (CBRN) events, processes always start at the local level. Even before the detection and analysis of agents can be undertaken, zoning, triage, decontamination, and treatment should be initiated promptly. Otorhinolaryngologists should be aware of PHI procedures for completing preliminary assessment and management together with emergency specialists or TEMS

"Bargaining Power in the European Council"

What resources grant heads of state and government influence in the European Council? Despite its political importance, the European Council has only been subject to limited research. Part of the explanation is the difficulties of conducting research on a political body that convenes behind closed doors, whose proceedings are undocumented, and whose participants are unusually hard to gain access to. This paper reports the results of a project designed to overcome the problems of previous research through a unique series of elite interviews with European heads of state and government. Drawing on general theories of negotiation, it isolates and illustrates three complementary sources of bargaining power in the European Council: state sources of power, institutional sources of power, and individual sources of power. Elite testimonies suggest that the state dimension of power is most fundamental, whereas the institutional and individual dimensions of power play a secondary role and mainly mediate the impact of structural power asymmetries

Three cases of resuscitative endovascular balloon occlusion of the aorta (REBOA) in austere pre-hospital environment—technical and methodological aspects

Abstract Background The present paper describes three cases where ER-REBOA® was used with partial aorta occlusion (AO), by performing a partial resuscitative endovascular balloon occlusion of the aorta or pREBOA, in an austere pre-hospital military environment. In addition, because no specific REBOA algorithm for pre-hospital environment exists yet, this paper seeks to fill this gap, proposing a new pragmatic REBOA algorithm. Methods Belgian Special Operations Surgical Team applied REBOA in three patients according to a decisional algorithm, based on the MIST acronym used for trauma patients. Only 3 ml, in the first instance, was inflated in the balloon to get AO. The balloon was then progressively deflated, and reperfusion was tracked through changes of end-tidal carbon dioxide (EtCO2). Results Systolic blood pressure (SBP) before ER-REBOA® placement was not higher than 60 mmHg. However, within the first 5 min after AO, SBP improved in all three cases. Due to the aortic compliance, a self-made pREBOA was progressively achieved while proximal SBP was raising with intravenous fluid infusion. Afterwards, during deflation, a steep inflection point was observed in SBP and EtCO2. Conclusions ER-REBOA® is suitable for use in an austere pre-hospital environment. The MIST acronym can be helpful to select the patients for which it could be beneficial. REBOA can also be performed with pREBOA in a dynamic approach, inflating only 3 mL in the balloon and using the aortic compliance. Furthermore, while proximal SBP can be convenient to follow the occlusion, EtCO2 can be seen as an easy and interesting marker to follow the reperfusion

Facing coagulation disorders after acute trauma

Problems/objectives: Trauma is the leading cause of mortality for persons between one and 44 years of age, essentially due to bleeding complications. Methodology: We screened the PubMed, Scopus and Cochrane Library databases, using specific keywords. Only publications in English were considered. Main results: The pathophysiology of trauma-induced coagulopathy (TIC) is complex and includes the classic "lethal triad" (i.e., haemodilution, acidosis, hypothermia) but may also include activation of protein C, endothelial and platelet dysfunction, and fibrinogen depletion. The time between trauma and treatment of the resultant massive bleeding should be as short as possible using techniques for rapid control of bleeding and avoiding aggravating factors (hypothermia, metabolic acidosis and hypocalcaemia). If given within three hours of injury, tranexamic acid (TXA) reduces all causes of mortality in trauma patients and reduces transfusion requirements. In a bleeding patient, crystalloids are preferred to colloids and the ratio of fresh frozen plasma to packed red blood cells should be at least 1:2. Damage control surgery (DCS) should be considered for patients who present with, or are at risk for developing, the "lethal triad", multiple life-threatening injuries or shock, and in mass casualty situations. DCS can also aid in the evaluation of the extent of tissue injuries and the control of haemorrhage and infection. Finally, there is currently no evidence of the added value of laboratory assays in the management of TIC. Conclusions: TIC appears quickly after trauma and should be anticipated and detected as soon as possible. TXA plays a central role in the management of such patients. Each institution should establish a local algorithm for the management of bleeding patients

Bargaining Power in the European Council

What grants influence in the European Council? Drawing on general theories of negotiation, this article isolates and illustrates three complementary sources of bargaining power in the European Council: state sources of power, institutional sources of power and individual sources of power. It reports the results of a unique series of elite interviews with European heads of state and government, foreign ministers and top-level civil servants. Elite testimonies suggest that the state dimension of power is the most fundamental, whereas the institutional and individual dimensions of power play a secondary role and mainly mediate the impact of structural power asymmetries.
