Validity of Arterial Hematocrits in Newborns
Archives of Pediatrics & Adolescent Medicine, 1988Various methods are used to obtain specimens for hematocrit determination in neonates. We evaluated arterial sampling and found this method to be acceptable. Arterial values correlated closely with simultaneously obtained venous samples. Venous blood obtained with a tourniquet had a significantly higher hematocrit than that obtained without a ...

The Splanchnic Hematocrit in Man
Acta Physiologica Scandinavica, 1963AbstractThe aim of the present work was to study to what extent the difference between the total body hematocrit and the hematocrit of the blood in the large vessels is caused by a low hematocrit in the splanchnic area. 131I‐labelled albumin and 51Cr‐labelled red cells were injected into an antecubital vein and samples were drawn simultaneously from ...

Microcirculatory hematocrit and blood flow
Journal of Theoretical Biology, 1988Direct measurements from many laboratories indicate that the oxygen tension in skeletal muscle is significantly less than in the large veins draining these tissues. Harris (1986) has proposed that because of the parallel anatomic arrangement of large arterioles and venules in skeletal muscle, a counter-current exchange between these vessels can occur ...

The Role of Hematocrit in Efficiency of Dialysis
Blood Purification, 1990To test the role of hematocrit (Hct), particularly when in the nearly normal range, on efficiency of dialysis, we analyzed the urea kinetics for 36 metabolically and hematologically stable patients on regular dialysis treatment and for 7 patients from this group before and after 3 months of treatment with human recombinant erythropoietin (rHuEPO).

Hematocrit of the fetal rabbit placenta
American Journal of Physiology-Legacy Content, 197551Cr-labeled erythrocytes and [125I]RISA were used simultaneously to measure the fetal rabbit whole-body and placental hematocrits (Hct) and to find the ratio of placental transit times of erythrocytes and plasma. The levels were injected into the heart of 21 fetal rabbits of 26--28 days gestation, and about 60 s mixing time, the placenta and a fetal ...

[The hematocrit and atherothrombotic cerebral infarcts].
Rivista di neurologia, 1986The authors compare the hematocrit values of 131 patients suffering from an acute cerebral atherothrombotic infarct, confirmed by CT scan, with those of 165 controls of the same age and sex. Both the analysis of the average by the Student's t test and the comparison between the distribution of frequencies by the chi square test, point out that ...

An hematocrit that has proved satisfactory because of its accuracy and simplicity and the small amount of blood required has already been described.1Recently, the efficiency of the instrument has been improved, by the substitution of a mechanical sealing device for the rubber band originally employed for the purpose of closing the lower end of the ...

Epigastric Pain With Falling Hematocrit
JAMA: The Journal of the American Medical Association, 1979History A 56-year-old woman was admitted with severe epigastric pain after having eaten a large meal. The patient was diaphoretic and had tachycardia. The pain radiated across the abdomen and was suggestive of biliary colic. The blood pressure was 110/70 mm Hg, with a regular pulse rate of 144 beats per minute.
