Platelet concentrate effects on thromboelastography

Journal of Cardiothoracic and Vascular Anesthesia, 1997
This study evaluated platelet effects on thromboelastography to determine how morphologically abnormal platelets affected native whole blood analysis.Prospective, controlled comparison.Tertiary care university hospital.Volunteer cardiac surgery patients.Fresh platelets were obtained from volunteers and were either treated normally or cryodisrupted with

Pathogen inactivation of platelet concentrates

Vox Sanguinis, 2010
Question 1 Has pathogen inactivation of PCs been implemented in your country ⁄ centre? If so, which technique is used? • If so, does this concern all PCs or only PCs for certain groups of patients? • How many inactivated PCs have been transfused and what was the experience with them so far? • Have you noticed any untoward reactions or effects that were,

Bacteriocidal Properties of Platelet Concentrates

Transfusion, 1974
Platelet concentrates were contaminated with predetermined numbers of bacteria isolated from patients. Staphylococcus epidermidis and Pseudo‐monas aeruginosa organisms were killed if the number introduced was less than 103. when 104 through 106 organisms were added, their growth was depressed for 24 hours and then slowly resumed.

Viral inactivation in platelet concentrates

Transfusion Clinique et Biologique, 1994
Although the current risk of posttransfusion infection is very low in North America and Western Europe, there continues to be considerable interest in measures to inactivate residual viruses in blood components. The human immunodeficiency virus is of greatest concern, but hepatitis C virus is also considered to be a significant problem.

Platelet counting using plasma platelet concentrate samples

Transfusion Medicine, 1992
SUMMARY. Platelet counting using samples of plasma from platelet concentrates prepared for transfusion was assessed. The methods employed included a manual phase‐contrast method, and counting with Coulter S Plus and Sysmex E‐2500 counters. All methods were reproducible (mean CV of 4.9, 2.2 and 1.4%, respectively).

Platelet concentration and platelet volume distribution in healthy cats

American Journal of Veterinary Research, 1984
SUMMARY An electronic particle counter and size analysis system were used to determine platelet count, mean platelet volume (mpv), platelet volume heterogeneity (sd of platelet volumes), and platelet mass values in feline platelet-rich plasma (prp) prepared by brief centrifugation of blood.

Preservation of platelet function in cryopreserved platelet concentrates with prostacyclin

Clinical & Laboratory Haematology, 2008
Prostacyclin (Epoprostenol) or a stable prostacyclin analogue (ZK 36,374) were added to platelet concentrates prior to cryopreservation. This resulted in significantly better preserved function of the thawed platelet concentrate, assessed by platelet aggregation to various concentrations of ADP, collagen and ristocetin, compared to control ...

Monitoring of platelet morphology during storage of platelet concentrates

Transfusion, 1989
During storage, human platelet concentrates progressively lose the capacity to survive and function in vivo after transfusion. A shape transformation from disc to sphere is the most reliable in vitro determinant for the loss of the in vivo survival of platelets.

The Functional Integrity of Platelets in Volume-Reduced Platelet Concentrates

Anesthesia & Analgesia, 2005
Premature and low-birth-weight infants usually require small-volume platelet transfusions to treat thrombocytopenia. Also, infants undergoing open-heart surgery with extracorporeal circulation and with compromised cardiac function are at risk for excessive intravascular volume.
