Marginal Donors Is there other Evidence?
Marginal Donors Is there other Evidence? Ware et al, (Lancet 2002) assessed 29 pairs of lungs rejected for use. 83% had no or mild pulmonary oedema, 74% had intact alveolar fluid clearance and 62% had normal histology
Marginal Donors Is there other Evidence? Fisher et al (Thorax 2004) assessed inflammatory markers in lungs not used for transplant. There was no difference in BAL IL8 or neutrophil counts in the excluded lungs. Trend towards more infection in used lungs

Aggressive management of lung donors classified as unacceptable: Excellent recipient survival one year after transplantation Straznicka, M et al. JTCVS August 2002, Volume 124, Number 2 250-258 Division of Cardiothoracic Surgery, University of California, Davis Medical Centre, Sacramento
Hypothesis Donor lungs with unacceptable PaO2/FiO2 ratios (<20 kPa) can be made acceptable with aggressive management and that 30-day and 1-year recipient outcomes with these lungs would not be significantly different than outcomes of recipients with traditionally ideal lungs Aggressive management of lung donors classified as unacceptable: Excellent recipient survival one year after transplantation Straznicka, M et al., JTCVS August 2002, Volume 124, Number 2 250-258
Results of OPO management 103 = 13.7 kPa 463 = 61.7 kPa Aggressive management of lung donors classified as unacceptable: Excellent recipient survival one year after transplantation Straznicka, M et al., JTCVS August 2002, Volume 124, Number 2 250-258

Conclusion Aggressive organ procurement management of donors initially considered unacceptable may increase the number of lungs available for transplantation Aggressive management of lung donors classified as unacceptable: Excellent recipient survival one year after transplantation Straznicka, M et al., JTCVS August 2002, Volume 124, Number 2 250-258
