REIMONDEZ, Santiago et al. Preservation fluid cultures. Clinical significance in liver transplantation. Medicina (B. Aires) [online]. 2021, vol.81, n.4, pp.555-558. ISSN 0025-7680.

The aim of this study was to determine the incidence of preservation fluids (PF) bacterial positive cultures, identify the germs involved, determine their correlation with infections in recipients during the postoperative period and compare outcomes in terms of morbidity, hospital stay and both patient and graft survival. We describe incidence and etiology of germs developed in PF cultures in our series and evaluate its impact on recipients. A prospective study in deceased donor liver transplants (LT) recipients was carried out from January 2014 to December 2017. Back table PF cultures were analized considering positive the development of any germs and negative to no signs of growth after 5 days. PF were classified as contamination or pathogens. Targeted antibiotic therapy was administered in the last ones. Recipients were divided in: PF (-) and PF(+). Recipients infections related to positive PF were analyzed. These were identified as “direct correlation” when the same germ grew up in PF. Hospital stay and 30 days follow up were compared. Eighty-eight patients PFs were included, 38% (33) had positive cultures, 28 (85%) of these were considered contamination and only 5 as pathogens. We found no differences in postoperative infections (p 0.840), ICU and total hospital stay (p 0.374 and 0.427) between both groups. Postoperative infections and hospital stay seem not to be influenced by PF cultures positivity. Treatment of isolated pathogens could have prevented infections, therefore, those groups that perform PF cultures should consider treatment in these cases and conclude prophylaxis when PF is negative or contaminated.
