A method is described for the catheterization of the carotid of the rat which permits blood volume determinations to be made on unanesthetized animals. The cell volume (P32) and plasma volume (T-1824) were measured simultaneously on the day after catheterization. The average Fcells factor was 0.739 (S.D., 0.053) in 11 normal rats and 0.726 (S.D., 0.041) in 10 splenectomized rats. In 50 unanesthetized normal rats the plasma volume averaged 3.90 ml/100 gm body weight. The blood and cell volumes calculated by using the Fcells factor of 0.74 and the separately determined plasma trapping' factor of 0.95 averaged 5.93 ml/ 100 gm and 2.14 ml/100 gm, respectively. These values agree closely with those determined from the simultaneous measurement of cell and plasma volumes and also with the values obtained on 27 normal rats under ether.

The Relationship

Abstract The plasma volume, red cell volume, or both were measured in 170 normal, anemic, or polycythemic subjects. For anemic subjects without a serum protein abnormality or splenomegaly, the relationship between hematocrit and red cell volume was linear and predictable. In patients with a serum monoclonal globulin on electrophoresis, the plasma voluem was significantly increased for the hematocrit in 30%, and the total blood volume was increased in 45%. The frequency of an elevated plasma volume was higher in patients with a markedly increased level of monoclonal protein. Reductions of abnormal proteins with chemotherapy were associated with declines in plasma volume. For a specific concentration, the serum viscosity was highest in patients with IgM proteins and lowest in patients with IgG globulins. Marked elevations in viscosity were noted only in sera with macroglobulinemia or with more than 5 g/dl of IgG or IgA globulins.

The Mean

Forty-two simultaneous measurements of plasma and cell volume with T-1824 and P32 were made on 18 normal monkeys ranging in weight from 3.4 to 7.1 kg. Nine determinations were made on two animals at varying intervals during a 16-month period. The mean values and standard deviations were as follows: cell volume 17.7 (S.D., 1.66) ml/kg; plasma volume, 36.4 (S.D., 3.98) ml/kg; blood volume, 54.0 (S.D., 4.72) ml/kg; Fcells factor, 0.83, (S.D., 0.046); venous cell percentage (hematocrit value x.96), 39.6; plasma protein (refractometer) 7.26 gm %. Variations among animals in plasma and blood volume, expressed in milliliters per kilogram were significantly greater than those observed in the same animal during the 16-month period.

Usual Feature

Dogs lightly anesthetized with ether, maintained between 23–24°C for 2 hours and rewarmed, were subjected to simultaneous determinations of red cell volume (Cr51) and plasma volume (T-1824). Red cell volume values were unchanged during the course of the experiment. Plasma volumes were significantly decreased during hypothermia and were transiently elevated during rewarming. Twenty-four hours after rewarming, total blood volume and plasma volume values were not significantly different from control values. It would seem that circulatory failure (‘rewarming shock’) is not a usual feature of rewarming following hypothermia of 2 hours duration.

Blood Volumes

In the Eisenmenger syndrome, indirect estimation of blood volumes may provide quite inaccurate information when seeking to define therapeutic strategies. With this in mind, we analyzed directly the red cell mass, plasma volume, and total blood volume in patients with pulmonary hypertension associated with congenital cardiac defects and erythrocytosis, comparing the results with the respective estimated volumes, and examining the changes induced by therapeutic hemodilution.Thus, we studied 17 patients with the Eisenmenger syndrome, aged from 15 to 53 years, in the basal condition, studying 12 of them both before and after hemodilution. We also investigated five individuals with minimal cardiac lesions, aged from 14 to 42 years, as controls. Red cell mass and plasma volumes were measured using [51 chromium]-sodium chromate and [131iodine]-albumin respectively. Hemodilution was planned so as to exchange 10% of the total blood volume, using 40,000 molecular weight dextran simultaneously to replace the removed volume. The mean values of the red cell mass, plasma volume and total blood volume as assessed by radionuclide techniques were 32%, 31% and 32% higher than the respective volumes as estimated using empirical mathematical formulas (p < 0.002). The measured total blood volume was also 19% higher in the patients compared with controls. Following a period of 5 days after hemodilution, we noted a 13% reduction in red cell mass (p = 0.046), and 10% reduction in total blood volume (p = 0.02), albeit with no changes in the plasma volume.We conclude that direct measurement of blood volumes is useful for proper management of these patients, and provides results that are considerably different from those obtained by empirical estimations.
