10 Protocol -Cardiac arrest -Transport to HSC. -Death certif. Preservation time(4h max.)Warm ischemic time (2h max.)Cold ischemic time-Cardiac arrest-Transport to HSC.-Death certif.-XR, serology-1st judge permission(preservation)-Topical cooling-Heparinization2nd judge and family perm.(harvest)-FB-Flush perfusion(300cc donor´s blood l Perfadex®)-Harvest.-Transport to HUPHM.-EXVIVO evaluation.-Implantation.This is the sequential events during the process of NHB donation.After cardiac arrest, that obviously has to be witnessed, the estrahospital advanced support units take the potential donor to HCSC, where ER staff certifies death. Immediately, permission for preservation is requested from the Judge on duty while X Ray and serologic tests are performed. After permission, topical cooling with Perfadex is initiated through 2 chest tubes in each side (the donor is also heparinized and put on ECMO and deep hypothermia to preserve intraabdominal organs). Judge and family consent, this time for donation, is requested and fiberoptic examination is performed as is done in BD donors. The next step is to go on with organ retrieval, excluding pulmonary vasculature as soon as possible and performing in situ evaluation of the grafts after flush perfusion with Perfadex. (300 ml of donor´s blood are passed through the pulmonary artery and gas analysis of the effluent in the left atrium is made. If PO2/FiO2 is higher than 300, corrected by temperature, lungs are considered valid. Then, grafts are taken to HUPHM for implantation. Recently we have included in this algorithm XVIVO evaluation of these grafts.

PaO2/FiO2 ratio, corrected by temperature, has always been above 300.

All together, represents a total ischemic time for the first lung of almost 10 hours, and for the second lung above 12 hours.10h12h
18 RESULTS.- PGD G 3 G 2 G 1 G 0 Incidence Duration Recovering In this figure you can see the incidence of Primary Graft Disfunction,, the duration of each grade, the average of patients that finally recovered from this situation and the hospital mortality rate associated with each grade of PGD. 5 patients suffered grade 1 PGD (in blue), with a duration of 48 hours till final recover and one of them died in multiorganic failure after a pneumonia. Five patients developed gade 2 PGD (in red) with a mean duration of 7 days and one of them died just before discharge after the withdrawal of a central venous catheter. 11 patients presented grade 3 PGD (in green), with a long duration as well, and 3 died (one died due to intestinal ischemia, another was transplanted in septic situation and another died after an episode of ventricular fibrilation.G 0IncidenceDurationRecovering30 days mortalityrate
