Forum for debate: Safety of allogeneic blood transfusion alternatives in the surgical/critically ill patient.

In recent years, several safety alerts have questioned or restricted the use of some pharmacological alternatives to allogeneic blood transfusion in established indications. In contrast, there seems to be a promotion of other alternatives, based on blood products and/or antifibrinolytic drugs, which lack a solid scientific basis. The Multidisciplinary Autotransfusion Study Group and the Anemia Working Group España convened a multidisciplinary panel of 23 experts belonging to different healthcare areas in a forum for debate to: 1) analyze the different safety alerts referred to certain transfusion alternatives; 2) study the background leading to such alternatives, the evidence supporting them, and their consequences for everyday clinical practice, and 3) issue a weighted statement on the safety of each questioned transfusion alternative, according to its clinical use. The members of the forum maintained telematics contact for the exchange of information and the distribution of tasks, and a joint meeting was held where the conclusions on each of the items examined were presented and discussed. A first version of the document was drafted, and subjected to 4 rounds of review and updating until consensus was reached (unanimously in most cases). We present the final version of the document, approved by all panel members, and hope it will be useful for our colleagues.

Actualización del Documento Sevilla

As allogeneic blood transfusion (ABT) is not harmless, multiple alternatives to TSA (AABT) have emerged, but there is a huge variability with respect to their indications and appropriate use. This variability results from the interplay of a number of factors, which include physicians specialty, knowledge and preferences, degree of anaemia, transfusion policy, and AABT availability. Since the ABBT are not harmless and may not meet costeffectiveness criteria, such avariability is unacceptable. The Spanish Societies of Anaesthesiology (SEDAR), Haematology and Haemotherapy (SEHH), Hospital Pharmacy (SEFH), Critical Care Medicine (SEMICYUC), Thrombosis and Haemostasis (SETH) and Blood Transfusion (SETS) have developed a Consensus Document for the proper use of AABTs. A panel of experts convened by these six Societies have conducted a systematic review of the medical literature and developed the «2013. Seville Document of Consensus on Alternatives to Allogeneic Blood Transfusion¼, which only considers those AABT aimed to decrease the transfusion of packed red cells. The AABTs are defined as any pharmacological and non-pharmacological measure aimed to decrease the transfusion of of red blood cell concentrates, while preserving the patient safety. For each AABT, the main question is formulated, positively or negatively, as: «Does or does not this particular AABT reduce the transfusion rate?¼ All the recommendations on the use of AABTs were formulated according to the GRADE (Grades of Recommendation Assessment, Development and Evaluation) methodology.

La transfusión de sangre alogénica (TSA) no es inocua, y como consecuencia han surgido múltiples alternativas a la TSA (ATSA). Existe variabilidad respecto a las indicaciones y buen uso de las ATSA. Dependiendo de la especialidad de los médicos que tratan a los pacientes, grado de anemia, política transfusional, disponibilidad de las ATSA y criterio personal, las ATSA se usan de forma variable. Puesto que las ATSA tampoco son inocuas y pueden no cumplir criterios de coste-efectividad, la variabilidad en su uso es inaceptable. Las sociedades españolas de Anestesiología y Reanimación (SEDAR), Hematología y Hemoterapia (SEHH), Farmacia Hospitalaria (SEFH), Medicina Intensiva y Unidades Coronarias (SEMICYUC), Trombosis y Hemostasia (SETH) y Transfusiones Sanguíneas (SETS) han elaborado un documento de consenso para el buen uso de la ATSA. Un panel de expertos de las seis sociedades han llevado a cabo una revisión sistemática de la literatura médica y elaborado el «2013. Documento Sevilla de Consenso sobre Alternativas a la Transfusión de Sangre Alogénica¼. Solo se contempla las ATSA dirigidas a disminuir la transfusión de concentrado de hematíes. Se definen las ATSA como toda medida farmacológica y no farmacológica, encaminada a disminuir la transfusión de concentrado de hematíes, preservando siempre la seguridad del paciente. La cuestión principal que se plantea en cada ítem se formula, en forma positiva o negativa, como: «La ATSA en cuestión reduce / no reduce la Tasa Transfusional¼. Para formular el grado de recomendación se ha usado la metodología GRADE (Grades of Recommendation Assessment, Development and Evaluation).

Alternativas terapéuticas de la hemorragia masiva / Treatment alternatives in massive hemorrhage

La hemorragia masiva es la principal causa de morbimortalidad en el paciente traumatizado, y una de las más importantes en el paciente sometido a cirugía mayor. El tratamiento convencional se basaba en la reposición inicial de la volemia con la infusión de grandes cantidades de fluidos y en la transfusión de hemoderivados, con objeto de asegurar la perfusión y oxigenación tisular. Hipotermia, acidosis y coagulopatía se considera triada letal. En esta revisión los autores abordan un enfoque terapéutico actualizado del manejo de la hemorragia masiva. Se preconiza infundir cristaloides de forma pautada (no masiva) para lograr una presión arterial sistólica de 85mmHg. La administración de hemoderivados debe ser precoz y con ratio 1:1:1 (cantidades equiparables de concentrados de hematíes, plasma y plaquetas), y si es posible, guiada por tromboelastograma a la cabecera del paciente. La coagulopatía puede ser precoz y tardía. Salvo el ácido tranexámico, se discute la relación coste-beneficio de fármacos prohemostáticos, como fibrinógeno, complejo protrombínico, y FVII recombinante (AU)

Massive hemorrhage is the main cause of mortality and morbidity in trauma patients, and is one of the most important causes in any patient following major surgery. Conventional treatment consists of volume replacement, including the transfusion of blood products, so that tissue perfusion and oxygenation may be maintained. Associated hypothermia, acidosis and coagulopathy is a lethal triad. This review focuses on the latest therapeutic management of massive hemorrhage. The authors advocate the use of crystalloids as per protocol (controlled volumes) in order to achieve a systolic blood pressure of 85mmHg. The administration of the three blood products (red cells, plasma, and platelets) should be on a 1:1:1 basis. Where possible, this in turn should be guided by thromboelastography performed at point of care near the patient. Coagulopathy can occur early and late. With the exception of tranexamic acid, the cost-benefit relationships of the hemostatic agents, such as fibrinogen, prothrombin complex, and recombinant F VII, are subject to discussion (AU)

Monitorización de la presión tisular de oxígeno (PtiO2) en la hipoxia cerebral: aproximación diagnóstica y terapéutica / Monitoring of tissue oxygen pressure (PtiO2) in cerebral hypoxia: diagnostic and therapeutic approach

Una de las causas principales de lesión cerebral secundaria es la hipoxia cerebral, fundamentalmente de origen isquémico. No obstante, la oxigenación tisular cerebral depende de múltiples variables fisiológicas y la hipoxia cerebral puede ser originada por una alteración de cualquiera de ellas. Aunque han sido desarrollados varios métodos de monitorización continua de la oxigenación cerebral en pacientes neurocríticos, la medición directa y continua de la presión de oxígeno en el tejido cerebral (PtiO2) es una realidad en el manejo de pacientes neurocríticos desde los últimos años. Esta técnica destaca por su fiabilidad y valor de la información que proporciona. En el presente artículo se expone una revisión de los aspectos más relevantes de la monitorización de la PtiO2 y se propone un protocolo para su interpretación. Este algoritmo pretende facilitar la identificación de diferentes tipos de hipoxia cerebral y la correcta elección terapéutica en el complejo proceso de toma de decisiones en pacientes neurológicos críticos en riesgo de hipoxia cerebral

One of the main causes of secondary cerebral injury is cerebral hypoxia, basically of ischemic origin. However, cerebral tissue oxygenation depends on multiple physiological variables and cerebral hypoxia may be caused by an alteration of any one of them. Although several methods of continuous cerebral oxygenation monitoring of neurocritical patients have been developed, direct and continuous measurement of the oxygen pressure in the cerebral tissue (PtiO2) has been a reality in the handling of the neurocritical patients over recent years. This technique is highlighted by its reliability and value of the information that it provides. This present article presents a review of the most outstanding aspects of the PtiO2 monitoring and proposes a protocol for the interpretation of this monitoring technique. This algorithm attempts to facilitate the identification of the different types of different cerebral hypoxia and of the correct therapeutic choice in the complex decision making process in neurocritical patients at risk of cerebral hypoxia

[Prevalence and treatment of anemia in critically ill patients]. / Prevalencia y tratamiento de la anemiaen el paciente crítico.

Anemia is a common condition among medical and surgical patients admitted to the intensive care unit (ICU) and generally has a multifactorial origin. In order to avoid the deleterious effects of anemia, 40% of ICU patients receive allogenic blood transfusion (ABT). This figure increases up to 70% if the ICU stay is longer than 7 days. However, ABT is associated with a dose-dependent increase in morbidity and mortality. In contrast, the administration of exogenous erythropoietin plus iron supplements, especially iv iron, improves anemia and reduces ABT requirements, although it does not reduce mortality. To ascertain whether treatment of anemia in the critically ill with exogenous erythropoietin and iron might improve outcomes and to optimize drug administration schedules and dosage, further studies with sufficient statistical power and adequate follow-up are warranted.

Prevalencia y tratamiento de la anemiaen el paciente crítico / Prevalence and treatment of anemia in critically ill patients

La anemia es muy frecuente en los pacientes médicos y quirúrgicos ingresados en la Unidad de Cuidados Intensivos (UCI), siendo generalmente de origen multifactorial. Para evitar los efectos deletéreos de la anemia, un 40% de estos pacientes suele ser transfundido, elevándose esta cifra al 70% si la estancia en UCI supera los 7 días. Sin embargo, la transfusión de sangre alogénica se asocia con un aumento dosis-dependiente de la morbilidad y mortalidad. Por el contrario, la administración de eritropoyetina recombinante junto con suplementos de hierro, especialmente hierro endovenoso, estimula la eritropoyesis y disminuye la necesidad de transfusión, aunque no desciende la mortalidad. Es necesario por tanto realizar más estudios, con poder estadístico suficiente y período de seguimiento adecuado, para conocer si el tratamiento de la anemia del paciente crítico con eritropoyetina y con hierro endovenoso mejora el pronóstico de estos pacientes, así como para optimizar las pautas y dosis de dichos tratamientos
