Papel de la perfusión normotérmica con oxigenación de membrana extracorpórea en la donación en asistolia controlada en España / Role of normothermic perfusion with ECMO indonation after controlled cardiac death in Spain

Spain has become one of the most active countries in donation after controlled cardiac death, using normothermic abdominal perfusion with ECMO in more than 50% of all donors – a situation contributed to by the creation of mobile teams to support hospitals lacking this technology. The donation process must be respectful of the wishes and values of the patients and their relatives, especially if there is pre mortem manipulation, and the absence of cerebral perfusion should be guaranteed. The liver is the most benefited organ by reducing biliary complications as well as the loss of grafts. In renal transplantation, the technique could contribute to reduce the incidence of delayed graft function. In addition, the procedure is compatible with surgical rapid recovery in hypothermia when there is also lung donation. The future lies in the consolidation of cardiac donation by extending normothermic perfusion to the thoracic cavity (AU)

España se ha convertido en uno de los países más activos en donación en asistolia controlada incorporando la perfusión abdominal normotérmica con ECMO en más del 50% de los donantes, a lo que ha contribuido la creación de equipos móviles para apoyo a hospitales carentes de esta tecnología. El proceso de donación debe ser respetuoso con los deseos y valores del paciente y sus familiares, especialmente si hay manipulación pre mortem, y debe asimismo garantizar la ausencia de flujo cerebral. El hígado es el órgano más beneficiado al reducirse las complicaciones biliares, así como la pérdida de injertos. En el trasplante renal podría contribuir a reducir la incidencia de retraso en la función inicial del injerto; además, el procedimiento es compatible con la cirugía súper rápida en hipotermia cuando también hay donación pulmonar. El futuro pasa por la consolidación de la donación cardíaca al extender la perfusión normotérmica a la cavidad torácica (AU)

The use of ECMO in ICU. Recommendations of the Spanish Society of Critical Care Medicine and Coronary Units. / Empleo de ECMO en UCI. Recomendaciones de la Sociedad Española de Medicina Intensiva Crítica y Unidades Coronarias.

The use of extracorporeal membrane oxygenation systems has increased significantly in recent years; given this reality, the Spanish Society of Critical Intensive Care Medicine and Coronary Units (SEMICYUC) has decided to draw up a series of recommendations that serve as a framework for the use of this technique in intensive care units. The three most frequent areas of extracorporeal membrane oxygenation systems use in our setting are: as a cardiocirculatory support, as a respiratory support and for the maintenance of the abdominal organs in donors. The SEMICYUC appointed a series of experts belonging to the three working groups involved (Cardiological Intensive Care and CPR, Acute Respiratory Failure and Transplant work group) that, after reviewing the existing literature until March 2018, developed a series of recommendations. These recommendations were posted on the SEMICYUC website to receive suggestions from the intensivists and finally approved by the Scientific Committee of the Society. The recommendations, based on current knowledge, are about which patients may be candidates for the technique, when to start it and the necessary infrastructure conditions of the hospital centers or, the conditions for transfer to centers with experience. Although from a physiopathological point of view, there are clear arguments for the use of extracorporeal membrane oxygenation systems, the current scientific evidence is weak, so studies are needed that define more precisely which patients benefit most from the technique and when they should start.

[Donation protocol following controlled cardiac death (Maastricht type III donation). First experience]. / Protocolo de donación tras la muerte cardiaca controlada (donante tipo iii de Maastricht). Experiencia inicial.

OBJECTIVE: To present our experience with the implementation of a donation protocol following controlled cardiac death (Maastricht type III donation). DESIGN: A retrospective descriptive and observational study was made. SETTING: Intensive Care Unit of a third-level university hospital. PATIENTS: Eight patients in an irreversible state, in which withdrawal of all life support had been agreed, were evaluated as potential donors. INTERVENTIONS: Application of the adopted protocol. VARIABLES OF INTEREST: Clinical data of donors, evaluation of a donation protocol following cardiac death, warm ischemia times, and short-term outcome of the recipients. RESULTS: Eight patients were evaluated. In one case donation was not possible because no cardiac arrest developed in the 120 minutes after extubation. The 7 remaining patients were effective kidney donors. Warm ischemia times were less than 23 minutes in all cases. Although 7 of the 14 recipients suffered delayed graft function, all of them achieved good renal function. CONCLUSION: Donation after cardiac death in patients in an overwhelming and irreversible state represents a potential source of donors not previously considered in this country. The prior development of a consensus-based protocol can help increase the number of organs in combination with those obtained after brain death. In our experience, the results of kidney transplants obtained from donors after cardiac death are good, and the success of these types of protocols could be extended to other organs such as the liver and lungs.

[Scarcity of spanish medical information in four Spanish journals (author's transl)]. / Escasez de información médica española en cuatro de nuestras publicaciones.

To evaluate if Spanish medical publications contribute to medical communication between Spanish medical workers of if in the contrary, Spanish authors gather most information from foreign journals, the percentage of Spanish references in Spanish journals has been calculated. Four Spanish journals and four foreign journals corresponding to the year 1977 have been reviewed. It has been found that the number of persons authoring an article in Spanish journals excedes in one author those of foreign papers, that Spanish papers have a mean of six more references than their foreign counterparts, and that there is a low number of Spanish references, decreasing even further if autoreferences are excluded. The findings are discussed with special emphasis on the low percentage of Spanish references in Spanish papers.
