More infoThe evaluation of cadaveric donors through the application of the donor-recipient risk index (DRI) since 2006 in the USA has been useful in the standardization of criteria during organ allocation in liver transplantation. This study aimed to apply the DRI > or < 1.7 and the relationship with morbidity and mortality, hospital stay, post-reperfusion syndrome, diagnosis, and origin, steatosis, BMI, cold ischemia times (WIT), Child-Pugh score and MELD score in our center.
Materials and MethodsDescriptive, cross-sectional, retrospective study. The medical records of all liver transplant patients were reviewed to extract demographic data and clinical characteristics based on the criteria established in the DRI assessment.
Results78 patients out of 303 met the criteria for evaluation registration, DRI < 1.7: 70.51% (mortality 16.36%), DRI > 1.7: 29.8% (mortality: 30.43). Post reperfusion syndrome: 47.82%. Cause of brain death: Traumatic brain injury: 43.58%, stroke: 41.02%, anoxic brain injury: 11.53%. Male: 60.25% and female: 39.74%. Donor graft weight: IDR <1.7: 1412 gr (700-2440g), WIT: 5.91 h (1.38-11.4 h), Age: 31 y (10-55), BMI: 24.93 (12.11-33.33), brain death time: 24 h and admission time: 4.3 hours, in the group with DRI > 1.7 graft weight: 1407 g (336-1900), WIT: 7.4 h (4-12.24), age: 51.22 y (29-67), BMI: 26.27 (26.23-29.38), brain death time: 24.5 h and admission time: 3 h. DRI group < 1.7: mild steatosis: 80%, moderate: 18% and in the IDR group > 1.7: mild steatosis: 87% and moderate in 13%. (see table 1)
ConclusionsMedical-surgical morbidity and mortality, post-reperfusion syndrome, hospital stay, stroke, BMI, and use of SPLIT grafts were higher in patients with IDR > 1.7. Other variables studied had no statistical relationship. We conclude that the IDR should be included in the evaluation of donors in our reality.
