The role of simulation to support donation after circulatory death with extracorporeal membrane oxygenation (DCD-ECMO)

Maintaining the viability of organs from donors after circulatory death (DCD) for transplantation is a complicated procedure, from a time perspective in the absence of appropriate organizational capabilities, that makes such transplantation cases difficult and not yet widespread in Poland. We present the procedural preparation for Poland’s first case of organ (kidney) transplantation from a DCD donor in which perfusion was supported by extracorporeal membrane oxygenation (ECMO). Because this organizational model is complex and expensive, we used advanced high-fidelity medical simulation to prepare for the real-life implementation. The real time scenario included all crucial steps: prehospital identification, cardiopulmonary resuscitation (CPR), advanced life support (ALS); perfusion therapy (CPR-ECMO or DCD-ECMO); inclusion and exclusion criteria matching, suitability for automated chest compression; DCD confirmation and donor authorization, ECMO organs recovery; kidney harvesting. The success of our first simulated DCD-ECMO procedure in Poland is reassuring. Soon after this simulation, Maastricht category II DCD procedures were performed, involving real patients and resulting in two successful double kidney transplantations. During debriefing, it was found that the previous simulation-based training provided the experience to build a successful procedural chain, to eliminate errors at the stage of identification, notification, transportation, donor qualifications and ECMO organ perfusion to create DCD-ECMO algorithm architecture.

Using simulation to create a unique regional ECMO program for the Greater Poland region

Background: “ECMO for Greater Poland” is a program being developed to serve the 3.5 million inhabitants of the Greater Poland region (Wielkopolska) based on an approach already implemented in the USA1 or Qatar.2,3Method: The program is complex and takes full advantage of the ECMO perfusion therapy opportunities to save the life of patients in the Greater Poland region. The main implementation areas are: – treatment of patients with hypothermia;4 – treatment of reversible severe respiratory failure;5 – treatment of acute intoxication resulting in cardiorespiratory failure6 or other critical conditions resulting in heart failure; – in the absence of response to treatment and eventual death, and with donor authorization, there is possible organ transplantation from a non-heart beating donor (NHBD) to another patient.7 This led to the development of a program for donation after circulatory death (DCD). Study: The program will help to put in place a Medical Rescue System including ECMO (Figure 1). It requires training in specialized resuscitation, perfusion, and transplantation teams in the implementation of this “ECMO rescue chain”. The main strength of the program is the widespread use of extracorporeal perfusion. All program arms in the use of ECMO should be implemented in parallel to maximize its positive impact.Figure 1. Organizational model of “ECMO for Greater Poland” – “ECMO rescue chain” scheme divided into three stages: prehospital, hospital/perfusion, and transplantation. As this organizational model is complex and expensive, we used high-fidelity medical simulation to prepare for the real-life implementation of our ECMO program. During 4 months, we performed scenarios including: – “ECMO for DCD” which includes: prehospital identification, CPR ALS (cardiopulmonary resuscitation advanced life support), perfusion therapy (CPR-ECMO or DCD-ECMO), inclusion and exclusion criteria matching, mechanical chest compression, transport, DCD confirmation, and donor authorization, the veno-arterial (VA) cannulation of a mannequins artificial vessels, and starting on-scene organ perfusion.7 – “ECMO for INTOXICATION” which includes: hospital identification (Department of Toxicology), poisoning treatment, CPR ALS, mechanical chest compression, VA cannulation, for the implementation of ECMO therapy and transport to another hospital (Department of Cardiac Surgery).6 – “ECMO for RRF” (reversible respiratory failure) which includes: hospital identification (Regional Department of Intensive Care) – inclusion and exclusion criteria matching, ECMO team transport (80 km), therapy confirmation, veno-venous cannulation for the implementation of perfusion therapy, and return transport (80 km) with ECMO to another hospital in a provincial city (Clinical Department of Intensive Care), where the veno-venous (VV) ECMO therapy was continued for the next 48 hours.5 The training programs, in a short time, resulted in a team being appropriately trained to successfully undertake the complex procedures. Soon after these simulations, Maastricht category II DCD procedures were performed involving real patients and resulting in two double successful kidney transplantations, for the first time in Poland. One month later, we treated two hypothermia patients and, for the first time in the region, also treated on ECMO an adult patient with reversible respiratory failure. Conclusions: The “ECMO for Greater Poland” program will allow the use of perfusion therapy for the inhabitants of Wielkopolska in a comprehensive manner, covering all critical disease states, by what appears to be a unique regional program in Poland. The full-scale, high-fidelity simulation enabled standardized training and testing of new, commonly, and rarely used procedures, and facilitated clinicians’ skills development.

The role of extracorporeal membrane oxygenation in patients after irreversible cardiac arrest as potential organ donors

The number of people waiting for a kidney or liver transplant is growing systematically. Due to the latest advances in transplantation, persons after irreversible cardiac arrest and confirmation of death have become potential organ donors. It is estimated that they may increase the number of donations by more than 40%. However, without good organization and communication between pre-hospital care providers, emergency departments, intensive care units and transplantation units, it is almost impossible to save the organs of potential donors in good condition. Various systems, including extracorporeal membrane oxygenation (ECMO), supporting perfusion of organs for transplantation play a key role. In 2016 the “ECMO for Greater Poland” program was established. Although its main goal is to improve the survival rate of patients suffering from life-threatening cardiopulmonary conditions, one of its branches aims to increase the donation rate in patients with irreversible cardiac arrest. In this review, the role of ECMO in the latter group as the potential organ donors is presented.

Active shooters — how close are they?

Recent terrorist attacks in the United States, Canada and Western Europe have shown an increase in the incidence of “Active Shooters” [1]. These ruthless and desperate assassins usually attack urban and poorly protected areas (lack of armed protection) that are densely populated [2]. Utilizing their strength, they realize that their plan is to maximize the number of casualties, without counting on the consequences of their actions. The basis of their action may be based on extremely radical views. Frequent outcomes for active shooters include suicide during an attack (90%) or the resolution of the threat by the authorities [3]. In response to the ever-increasing number of assassinations and the risk of such incidents in one’s immediate surroundings, comprehensive education should be widely spread. Thus, it is important to promote appropriate behaviour, rules of reaction during an attack by an armed assailant, as well as cooperation with incoming service personnel. Such actions will not only help one prevent, but also allow one to prepare for such incidences.

AED use in public places: a study of acquisition time

BACKGROUND Sudden cardiac arrest (SCA) is a frequent cause of death in the developed world. Early defibrillation, preferably within the first minutes of the incident, significantly increases survival rates. Accessible automated external defibrillators (AED) in public areas have been promoted for many years, and several locations are equipped with these devices. AIM The aim of the study was to assess the real-life availability of AEDs and assess possible sources of delay. METHODS The study took place in the academic towns of Poznan, Lodz, and Warsaw, Poland. The researchers who were not aware of the exact location of the AED in the selected public locations had to deliver AED therapy in simulated SCA scenarios. For the purpose of the trial, we assumed that the SCA takes place at the main entrance to the public areas equipped with an AED. RESULTS From approximately 200 locations that have AEDs, 78 sites were analysed. In most places, the AED was located on the ground floor and the median distance from the site of SCA to the nearest AED point was 15 m (interquartile range [IQR] 7-24; range: 2-163 m). The total time required to deliver the device was 96 s (IQR 52-144 s). The average time for discussion with the person responsible for the AED (security officer, staff, etc.) was 16 s (IQR 0-49). The AED was located in open access cabinets for unrestricted collection in 29 locations; in 10 cases an AED was delivered by the personnel, and in 29 cases AED utilisation required continuous personnel assistance. The mode of accessing the AED device was related to the longer discussion time (p < 0.001); however, this did not cause any significant delay in therapy (p = 0.132). The AED was clearly visible in 34 (43.6%) sites. The visibility of AED did not influence the total time of simulated AED implementation. CONCLUSIONS We conclude that the access to AED is relatively fast in public places. In the majority of assessed locations, it meets the recommended time to early defibrillation of under 3 min from the onset of the cardiac arrest; however, there are several causes for possible delays. The AED signs indicating the location of the device should be larger. AEDs should also be displayed in unrestricted areas for easy access rather than being kept under staff care or in cabinets.
