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

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.

Plasma and Blood Volume in Space

The American Journal of the Medical Sciences, 2007
Body fluid regulation is affected by gravity. The primary mechanisms of the etiology of hypovolemia found in simulation studies on earth and after space flight are different. The increased diuresis after increase of central blood volume postulated by Henry Gauer could not be found.

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 ...

Measurement of plasma volume in pregnancy

Clinical Science, 1992
1. Determination of the plasma volume in pregnant women is a useful research tool and may become an important clinical measurement. We used three methods to determine plasma volume using Evans Blue dye: (1) the ‘usual’ method, measuring serum absorbance at a wavelength of 610 nm, (2) a two-wavelength method, and (3) precipitation of non-albumin ...

STATUS OF HUMAN PLASMA AS A PLASMA VOLUME EXPANDER

Plastic and Reconstructive Surgery, 1960
Review of Plasma Studies Although transfusions of plasma were suggested, they were not tried as substitutes for blood transfusions during World War I. Numerous studies of plasma were made during the period between World War I and World War II, but most of them are not particularly relevant to this report. Wartime enthusiasm for the use of plasma began

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.

Effects of Large Volume-Hemodilution Perfusion on Plasma Volume, Plasma Proteins and Plasma Electrolytes in Neonatal Piglets

Biology of the Neonate, 2009
Two groups of 15 neonatal piglets underwent arteriovenous perfusion with the chest closed, at normothermia and without an oxygenator in the system until complete mixing of the blood and priming fluid was accomplished. The extracorporeal circuit was primed in one group with a warm (38 °C) buffered Ringer-lactate solution, and in the second group with an

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.
