Abstract
Pre-operative anaemia and the need for intra-operative transfusion have been associated with increased morbidity and mortality following cardiac and major non-cardiac surgery. Anaemia is highly prevalent in patients with severe chronic liver disease. Whether this correlates with an altered morbidity and mortality following liver transplant has not been established. METHODS: Prospectively collected data was analysed for the period 1998-2012. Donor and recipient characteristics, blood profiles and complications were recorded. Graft and patient survival was calculated. All patients were followed up for 1 year or until death. Pre-operative haemoglobin levels were correlated with patient demographics and outcome using a binary logistic regression analysis. RESULTS: Pre-operative anaemia, according to WHO criteria, occurred in 73% of patients. Anaemia was more common with advanced liver disease (higher MELD score). As MELD score increased, Haemoglobin levels dropped. Anaemic patients were more commonly transfused (p < 0.001), spent longer ventilated (7 day vs 5 days, p = 0.005) and required longer ITU stays (8 days vs 6 days, p = 0.015). Pre-operative anaemia did not correlate with patient morbidity or mortality. CONCLUSIONS: Reduced haemoglobin levels reflect the severity of chronic liver disease but are not an independent risk factor for a poor outcome following liver transplantation.
