[Hemodynamics in double plasmapheresis in lung cancer]

The effect of double plasmaphoresis upon the central hemodynamics in 37 cases of pulmonary carcinoma was studied. Plasmaphoresis was aimed at the storage of an autologous transfusional medium to compensate the operative blood loss. Taking 400-500 cc of plasma does not cause any hemodynamic changes in patients without heart disease signs. The choice between surgical intervention and repeated plasmaphoresis should be made with regard to the time necessary for normalization of the circulatory parameters following plasmaphoresis.
