Mean potassium levels in perfusion fluid during DHOPE and in recipient blood samples during subsequent orthotopic liver transplantation (OLT). At baseline (time point zero), samples of the perfusion fluid were taken before the liver was connected to the perfusion device (Liver Assist). Potassium levels in the perfusion fluid increased significantly during the first 30 minutes of DHOPE (*P < .001), and stabilized thereafter. During OLT of DHOPE‐preserved livers, blood potassium levels decreased significantly after reperfusion (**P = .003). Moreover, at the time of graft reperfusion, blood potassium levels were significantly lower in DHOPE patients when compared to potassium levels at that time point in control patients (***P = .03). Note the different Y‐scales for DHOPE and NMP
