D URING measurements of total body red cell volume by the Cr51-technic in this laboratory, normal or elevated values were observed in several patients with moderate “anemia”, as judged by the hematocrit of peripheral venous blood. #{176} In each instance, marked to massive splenomegaly was present and increased localization of red cell radioactivity in the spleen was noted by body surface scann...

objective: to investigate the decrease in hemoglobin concentration and hematocrit during elective surgery. methods: this was a prospective study being performed in nemazee hospital of shiraz university of medical sciences. we included a total of 50 american society of anesthesiology (asa) i and ii patients undergoing elective minor surgeries. perioperative fluid administration was performed for...

Cigarettes have a bad impact on health, one of which is the most fundamental to blood, that hematocrit. The goal research were comparing and correlating cigarettes with hematocrit,used cross sectional design in Mulyasari Subang Village, West Java, 55 male respondents. Respondents who smoked 27 people. Smoking duration 15.93 years ± 7.54. type filters, 55.6%. hematocrit value 61.8% low category,...

OBJECTIVE To discover the effects of the lowest hematocrit during cardiopulmonary bypass on end-organ function and mortality in patients who did not receive red blood cell transfusion and to identify predictors of nadir hematocrit. METHODS From November 1, 2004, to October 1, 2009, 7957 patients underwent cardiac surgery supported by cardiopulmonary bypass and were not transfused. The relatio...

The association of hematocrit with development of hypertension over 9 years was studied in 784 hypertension-free Japanese men aged 40 to 59 years. The age-adjusted relative risk for hypertension above the borderline level and definite hypertension increased in a dose-dependent manner as hematocrit level increased (P for trend: 0.007 and 0.001, respectively). After controls for other potential f...

conclusions although some studies showed association between anemia and extubation failure, the current study could not confirm it. the study showed that males, regardless of the hct level, had a better extubation success rate than those of females. results there was no significant association between the level of hct concentration and extubation failure (8.9% vs. 9.2%, p = 0.507). gender and a...

To determine the direct effects of hematocrit on intestinal oxygen consumption and to determine whether an optimal hematocrit exists for intestinal oxygenation, we perfused isolated canine gut loops at a constant pressure (120 mm Hg) and varied hematocrit from 80% to 10%. As hematocrit fell, blood flow rose while arterial oxygen content fell. The regression of blood flow on hematocrit was linea...

Hematocrit has been implicated in the triggering of cardiovascular events and the development of cardiovascular disease. Studies have demonstrated the reliability of hematocrit at rest, however, data are lacking about hematocrit during repeated acute stress exposures. The current study assessed the reliability of hematocrit during rest and stress. Hematocrit was measured in two sessions during ...

Failling hematocrit values are traditionally used to observe the course of active bleeding, since hematocrit values usually reflect acute blood losses. However, evidence from the literature suggests that, after volume replacement, some degree of normovolemic hemodilution may be desirable and that return to normal hematocrit values is not necessarily the appropriate goal of transfusion therapy. ...
