Platelets and whole blood coagulation
Perfusion, 2000In our early work in developing activated clotting time (ACT) assays, it became apparent that changes occurred in coagulation times as a whole blood sample aged (0-6 h). Subsequent studies showed that the coagulation parameters of plasma obtained from the samples remained stable during this time frame.

Whole Blood Platelet Aggregometry
2017Light transmittance aggregometry is the historical reference method for platelet function testing and continues to be used extensively. Whole blood impedance lumiaggregometry represents an updated methodology that provides for simplified specimen management, an assay milieu that replicates in vivo platelet activation conditions, improved ...

A microcomputer oximeter for whole blood
American Journal of Physiology-Heart and Circulatory Physiology, 1983A system is described for measuring the percent of oxyhemoglobin in flowing whole blood. The system consists of an Apple II+ computer, a commercially available analog-to-digital converter, a simple electronic circuit to illuminate blood with light at two appropriate wavelengths, and a short program in BASIC.

Whole blood in trauma resuscitations
The American Journal of Emergency Medicine, 1985As is true in all serious endeavors, methodological trends are established and later surpassed by newer ones in medicine. The long post-operative hospital stays of years past have given way to outpatient surgical centers, use of alpha vasopressors has yielded to frequent use of dopaminergic pressors, and use of whole blood, widely practiced in the past

ABSTRACT To the Editor:— Certain aspects of the article "Effect of Bishydroxycoumarin (Dicumarol) on Clotting Time of Whole Blood" by Mayer and Connell in The Journal, June 30, page 806, merit further discussion. Until the appearance of this paper, there were serious questions about the rationale of Dicumarol usage. The general opinion had been that it

THE TRANSFUSION OF WHOLE BLOOD
Australian and New Zealand Journal of Surgery, 1941Summary.1. An improved arm‐to‐arm transfusion device is offered which provides for a continuous stream and avoids other disadvantages associated with syringes.2. It is possible in a high percentage of cases to transfuse a pint of blood within six minutes of running time.3. If cutting down on and canalization of donor's vein are permitted, the operation

To the Editor:— InThe Journal, Sept. 17, 1955, page 171, Krevans and Jackson described a "Hemorrhagic Disorder Following Massive Whole Blood Transfusions" associated with a fall in platelet level. It is well known that simple reduction of circulating platelets is not enough to produce hemorrhage.

To the Editor:— Dr. Lewisohn maintains that the term "whole" blood, as suggested by Dr. Scannel, should include "citrated" blood. I respect the opinions of both of these men. We have been using primarily "citrated" blood for twenty-three years in our obstetric service. I've always differentiated between "citrated" blood and "whole" blood because even

Methods of Storage Of Whole Blood
JAMA: The Journal of the American Medical Association, 1967To the Editor:— "The Indications for Transfusion of Freshly Drawn Blood" by Harold A. Oberman, MD ( 199 :93, 1967) is an excellent review of the clinical situations that require freshly drawn blood. Another currently available method of storing whole blood with no added acid-citrate-dextrose (ACD) solution is the use of the blood pack 500-ml ion ...
