Abstract: To measure postmortem extravascular lung water(ELW)by using the non-isotope method and to compare to the various parameters of pulmonary edema, 21 canines were divided into two groups, control and pulmonary edema. After canines were put to death, the animal lungs were homogenated, weighted and roasted. ELW were measured by adapting the hemoglobin method. Multinomial parameters of the pulmonary edema were calculated by standard formulae. In control group ELW, extravascular dry weight(EDW)and lung total water(LTW)were(4.46±0.30)mL/kg,(1.48±0.20)mL/kg and(7.56±0.98)mL/kg, respectively. The results showed that the method of measuring postmortem, ELW was simplified and the measuring errors was reduced. Among the various parameters of pulmonary edema ELW was the most sensitive in responding to the change of the lung water. EDW can be used to show the type of pulmonary edema.
