[Optimal cationic composition of perfusates in relation to temperature during preservation of the liver]

Search for the optimal concentrations of potassium, sodium, magnesium, calcium and H+ under different temperature conditions of preservation was performed in 193 experiments with the 2 h perfusion of the isolated rabbit liver. A nonlinear relation was established between the optimal cationic content of the perfusate and the liver preservation temperature. The sharpest changes to the optimal concentration of cations in the perfusate were found to start when the liver preservation temperature had dropped lower than 10-12 degrees C.
