Red cell volume (RCV) and plasma volume (PV) were determined separately in 21 cases of pheochromocytoma before and after surgery. The following results were obtained:
1) A typical pattern of circulating blood volume in pheochromocytoma could be summarized as follows: a) Reduction of RCV. b) Change of PV in proportion to catecholamine secretion of the tumor. c) Dissociation between peripheral hematocrit and total body hematocrit.
2) In some cases (especially in male), however, no reduction of RCV was observed.
3) After the treatment with receptor blockers, no change of RCV with some changes of PV in proportion to the effect of the blockers was observed.
A standard method for “Blood overtransfusion” was discussed.
