Plasma volume studies with four different plasma volume expanders

Journal of Surgical Research, 1971
Abstract Thirty-four patients were divided into four groups. Patients in each group received 500 ml. of one of the four plasma expanders; 6 per cent hydroxyethyl starch, 3.5 per cent Haemaccel, 6 per cent dextran, and frozen plasma. Six per cent hydroxyethyl starch produced significant postinfusion plasma volume expansion when compared with the other

Estimating plasma volume from red cell volume

Nuclear Medicine Communications, 1999
Following the withdrawal of the only licensed supply of 125I-HSA in 1997, most UK centres now simply estimate plasma volume from a knowledge of the red cell volume and venous haematocrit. We compared measured and estimated plasma volume in 107 consecutive patients who had had red cell and plasma volume measured independently in the conventional way. In

Plasma volume substitution

Acta Anaesthesiologica Scandinavica, 1988
Blood loss up to 10–15% of the total blood volume can be substituted by mere crystalloids. A quicker and more stable volume replacement can be accomplished with colloid solutions. Combination of artificial colloids (e.g., dextran 60, dextran 70 or hydroxyethyl starches with high degree of hydroxyethylation) with crystalloids (isotonic balanced ...

Plasma Volume during Weight Lifting

International Journal of Sports Medicine, 2008
The magnitude and pattern of the hematocrit (Hct), hemoglobin (Hb), and plasma volume (PV) responses during and upon recovery from two resistance training protocols based on either a ten-repetition maximum (10 RM) or five-repetition maximum (5 RM) resistance was examined.

Does Dihydroergotamine Reduce Plasma Volume?

Acta Pharmacologica et Toxicologica, 1986
Abstract: Indications on a plasma volume reduction by dihydroergotamine (DHE) has been found in earlier studies. This study was made in order to further evaluate such a change. In animal experiments (sheep, n = 10) measurements were performed of red blood cell volume and plasma volume using radioactive labelling techniques.

Plasma Volume and Plasma Colloid Osmotic Pressure

Scandinavian Journal of Clinical and Laboratory Investigation, 1969
Ten different specimens of plasma were concentrated by ultrafiltration to a colloid osmotic pressure (COP) of 50–80 cm H2O, then diluted by the addition of 0.15 M sodium chloride solution. The relationship between the changes in volume (V) and COP satisfy the equation V: COP0.687 = K.

Significance of plasma skimming and plasma volume expansion

Journal of Applied Physiology, 1992
The organs associated with plasma volume expansion, i.e., the red bone marrow, the enlarged spleen, and the uteroplacental complex, are arteriovenous shunts with an interposed sinusoidal stroma able to skim off plasma-rich blood. In the spleen, plasma separation is an integral part of the hemoconcentration.

Exercise stroke volume relative to plasma-volume expansion

Journal of Applied Physiology, 1988
The effects of plasma-volume (PV) expansion on stroke volume (SV) (CO2 rebreathing) during submaximal exercise were determined. Intravenous infusion of 403 +/- 21 ml of a 6% dextran solution before exercise in the upright position increased SV 11% (i.e., 130 +/- 6 to 144 +/- 5 ml; P less than 0.05) in untrained males (n = 7). Further PV expansion (i.e.

Plasma volume late in pregnancy

American Journal of Obstetrics and Gynecology, 1950
Abstract Plasma volume was determined by chromatographic extraction and spectrophotometric determination of Evans blue in pregnant women a month before delivery and at term, as well as in nonpregnant control subjects. The mean value at term was not significantly lower than that at the the thirty-sixth week.

Safety of Plasma Volume Expanders

The Journal of Clinical Pharmacology, 2011
Hypovolemia from a range of etiologies can lead to severe morbidity and mortality unless blood volume and tissue perfusion are restored. The treatment of hypovolemia has included the improvement and restoration of blood volume loss by the intravenous infusion of plasma expanding therapeutic agents.
