BACKGROUND Current treatment recommendations for patients with polycythemia vera call for maintaining a hematocrit of less than 45%, but this therapeutic strategy has not been tested in a randomized clinical trial. METHODS We randomly assigned 365 adults with JAK2-positive polycythemia vera who were being treated with phlebotomy, hydroxyurea, or both to receive either more intensive treatment...
The effect of isovolemic hemodilution on red blood cell flow distribution was studied in complete self-contained microvessel networks of the rat mesentery. Hematocrit, diameter, and length of all vessel segments as well as the topological structure were determined in control networks (systemic hematocrit, 0.54) and after hemodilution (systemic hematocrit, 0.30). Hemodilution was performed by ex...
OBJECTIVE To investigate the relationship between mean arterial blood pressure and hematocrit in a population of treated diabetic patients and a control population of healthy individuals. RESEARCH DESIGN AND METHODS Data on hematocrit and blood pressure were obtained from 129 diabetic subjects (87 women and 42 men) and 103 healthy subjects (76 women and 27 men) enrolled in a cross-sectional s...
OBJECTIVES To determine the effects of low, normal, and high hematocrit levels on glucose meter measurements and to assess the clinical risks of hematocrit errors. DESIGN Changes in glucose measurements between low and high hematocrit levels were calculated to determine hematocrit effects. The differences between glucose measured with meters and with a plasma glucose method (YSI 2300) also we...
OBJECTIVE The purpose of this study was to provide a viable alternative to routine postpartum hematocrit measurement, by a determination of the clinical risk factors that identify patients with anemia and an examination of the resulting cost savings. STUDY DESIGN In this retrospective review, cases (postpartum hematocrit level, <26%; subgroup hematocrit level, <23%) and control subjects were ...
Microvascular hematocrit and its possible relation to oxygen supply were systematically examined. We studied the red cell volume fraction (hematocrit) in arterial blood and in capillaries under a variety of circumstances. Control capillary hematocrit averaged 10.4 +/- 2.0% (SE) and arteriolar (14.2 micrometer ID) hematocrit averaged 13.9 +/- 1.2% in cremaster muscles of pentobarbital-anesthetiz...
conclusions the association of the 1st trimester high hb and hct with preeclampsia was revealed in this study, therefore it could be used as a prediction factor for early preeclampsia diagnosis. results preeclampsia incidence was 5.1% in our study. mean hb was 12.38 ± 1.69 g/dl in the preeclampsia group and 11.8 ± 1.18 in the non-preeclampsia group, and mean hct was 37.74 ± 5.15% in the preecla...
objective: preeclampsia is one of the most important complications of pregnancy that is associated with increased morbidity and mortality. the aim of this study was to investigate the relation between serum iron status and ferritin with pre-eclampsia. materials and methods: this case control study evaluated 33 preeclamptic patients and 33 normal pregnant women before parturition in imam hossein...
Regional cerebral blood flow decreases during chronic hyperglycemia, a condition frequently associated with elevated hematocrit. To test the hypothesis that an elevated hematocrit is responsible for the reduced regional cerebral blood flow during chronic hyperglycemia, I used isovolemic hemodilution to normalize the hematocrit in seven normoglycemic and seven streptozotocin-treated (hyperglycem...
To assess a possible relationship between hematocrit level and intraocular pressure (IOP) in both men and women.Data were collected from medical records of individuals examined at a screening center in Israel between the years 2000 and 2013. Hematocrit levels were categorized as low, normal, and high and by sex; IOP values were categorized as < 18 mmHg and ≥18 mmHg.Cross-sectional analysis was ...
