Accuracy of blood volume estimations in critically ill children using 125I-labelled albumin and 51Cr-labelled red cells. 1977

O Linderkamp, and H Holthausen, and J Seifert, and I Butenandt, and K P Riegel

Blood volume was estimated using 51chromium labelled red cells and 125iodinated human serum albumin in 5 children with sepsis, in 6 burned children and 7 children with acute lymphoblastic leukaemia. Studies of the equilibration pattern demonstrated that the mixing time of labelled red cells was prolonged to 40 minutes or more in 5 children, indicating the existence of slowly circulating red cells. Mixing of labelled albumin was complete within 10 minutes in 15 patients and within 20 minutes in all the children studied. In a burned patient with severe sepsis, exchange transfusion improved the clinical state and normalized the equilibration pattern of labelled red cells. The mean body/venous haematocrit ratio was 0.893+/-0.018 (SD) in the children with sepsis, 0.859+/-0.052 in the burned patients, and 0.916+/-0.078 in the children with acute lymphoblastic leukaemia, increasing with spleen size in the latter group.

D001811 Blood Volume Determination Method for determining the circulating blood volume by introducing a known quantity of foreign substance into the blood and determining its concentration some minutes later when thorough mixing has occurred. From these two values the blood volume can be calculated by dividing the quantity of injected material by its concentration in the blood at the time of uniform mixing. Generally expressed as cubic centimeters or liters per kilogram of body weight.
