Hypothesis
Lower perfusate hemoglobin levels would be associated with a greater risk of posttransplant early allograft dysfunction.
Conclusion
Lower perfusate hemoglobin levels were associated with a higher incidence of early allograft dysfunction and higher levels of liver injury markers.
Supporting Evidence
- Higher initial hemoglobin was associated with a lower risk of early allograft dysfunction (0% vs. 55.6%).
- Perfusate hemoglobin decreased after NMP initiation.
- Higher hemoglobin levels correlated with lower recipient peak transaminase levels.
Takeaway
This study found that keeping hemoglobin levels high during liver machine perfusion can help prevent problems after a liver transplant.
Methodology
A pilot retrospective analysis of adult donor livers undergoing normothermic machine perfusion was conducted, assessing the association between hemoglobin levels and early allograft dysfunction.
Potential Biases
The retrospective nature of the study may introduce selection bias.
Limitations
The study has a small sample size and is a single-center study, which may limit the generalizability of the findings.
Participant Demographics
The median donor age was 47 years, with 13% over 60 years old; the majority of donors were from donation after cardiac death.
