Abstract
La tasa de obtención de pulmones para trasplante es baja y, por ello, los órganos disponibles muy escasos. Esto da lugar a una mortalidad importante en lista de espera y a que ni se contemple el trasplante a pacientes que podrían beneficiarse del mismo. El trasplante de donante en asistolia controlada ya está bien establecido pero los donantes en asistolia no controlada podrían permitir ampliar el número de pulmones trasplantables. Sin embargo, el inevitable tiempo de isquemia caliente hace que este tipo de donantes se consideren con criterios expandidos o marginales, siendo más incierto el grado de funcionalidad del implante. La perfusión pulmonar ex vivo, o más comúnmente conocida como EVLP (Ex Vivo Lung Perfusion), es un procedimiento capaz de evaluar la función del pulmón antes del trasplante e incluso de reacondicionarlo, convirtiendo en trasplantable un órgano previamente rechazable. Durante la EVLP, la administración de tratamientos a través de la solución de perfusión o a través de la vía aérea son métodos establecidos para el mantenimiento o reacondicionamiento pulmonar. El sevoflurano y la lidocaína están siendo investigados por sus propiedades antiinflamatorias y antiapoptóticas; su efecto, por vía inhalatoria el primero y en perfusión el segundo, podría modular el daño pulmonar durante la EVLP...
The number of lungs for transplantation is low and, therefore, the availability of organs is scarce. This produces a significant mortality on the waiting list and the issue that transplantation is not regarded for all patients who could benefit from it. Donor transplantation in controlled asystole is already well established, but donors in uncontrolled asystole could allow the number of transplantable lungs to be expanded. However, the inevitable time of hot ischemia means that this type of donors is considered as marginal, being more uncertain the degree of success of the implant.Ex vivo lung perfusion, or more commonly known as EVLP (Ex Vivo Lung Perfusion), is a procedure intended to test the function of the lung before transplantation and even reconditioning it, making suitable a formerly discardable graft. During EVLP, administration of treatments through the infusion solution or through the airway are well-known methods for lung maintenance or reconditioning. Sevoflurane and lidocaine are being investigated for their anti-inflammatory and anti-apoptotic properties; its effect, by inhalation the former and by infusion the latter could modulate lung damage during EVLP...
