Potential Role for Pulmonary Surfactant in Lung Transplantation
Since its introduction in 1954 by Murray and colleagues, allotransplantation has greatly improved the quality, as well as the duration of life for those involved.1 The discovery of immunosuppressant drugs advanced long term efficacy of transplantation and led to a further improvement in the quality of life. Unfortunately, maximal potential benefits have never been achieved. As with a number of other organs, particularly kidneys, livers and hearts, there are lengthy waiting lists for suitable lungs. This lack of sufficient organs results, not only from the limited number of donors, but in part because many of the lungs available for transplant are judged unsuitable, due to edema, aspiration or contusion. The short period over which lungs remain clinically viable, presently 6–8 hours, also limits the availability of these organs. Furthermore, the practice of maintaining brain-damaged potential organ donors on respirators using high oxygen levels and vigorous mechanical ventilation contributes to the paucity of available lungs.
