title: Electrical impedance of the liver during experimental long-term liver preservation.
abstract: Measurements of electrical impedance were performed to assess ischemic damage in the rabbit liver during long-term preservation with University of Wisconsin (UW) or histidine-tryptophan-ketoglutarate (HTK) solution. The impedance was measured at a frequency of 200 Hz after in situ perfusion and after cold storage for 24 and 48 hours in UW or HTK solution (six livers per group). Z(200 Hz) was significantly higher (P < .01) after 48 compared with 24 hours of cold storage with both protection solutions without significant differences between the livers preserved with both solutions. Electrical impedance was observed to be a sensitive indicator of liver damage during long-term protection, showing similar preservation quality for both preservation solutions.
