Modulation of Platelet Surface Adhesion Receptors during Cardiopulmonary Bypass

Anesthesiology, 1991
Alterations in platelet receptors critical to adhesion may play a role in the pathogenesis of the qualitative platelet defect associated with cardiopulmonary bypass. Using flow cytometry, we measured changes in the following platelet surface adhesive proteins: the von Willebrand factor receptor, glycoprotein Ib; the fibrinogen receptor, glycoprotein ...

Root Surface Caries: A Complication of the Jejunoileal Bypass

Obesity Surgery, 2000
A patient developed root surface caries and loss of teeth following the jejunoileal (JI) bypass. We attempted to confirm the association of root surface caries with the JI bypass and explore the mechanisms by which it occurs.The number of root surface caries per year after, and an equal period of time before, a JI bypass was determined in 18 patients ...

The influence of compliant surfaces on bypass transition

Experiments in Fluids, 2007
The objective of the work was to investigate the effect of compliant surfaces on the receptivity and bypass transition of a boundary layer. Hot wire measurements in the pre-transitional and transitional boundary layers on nine different compliant and one rigid surface with identical geometries were made.

Blood - Artificial Surface Interactions during Cardiopulmonary Bypass

The International Journal of Artificial Organs, 1990
Evaluation of the biocompatibility of four different types of oxygenator (bubble, membrane, hollow fibre and ‘hybrid’) was performed on 26 patients undergoing cardiopulmonary bypass during elective coronary surgery. More platelet derangement and an increased degree of hemolysis, revealed by higher plasmatic concentration of beta-thromboglobulin ...

Blood-Surface Interactions During Cardiopulmonary Bypass

Journal of Cardiac Surgery, 1993
The interaction between blood and the synthetic surfaces of the heart-lung machine activates plasma protein systems and blood cells to produce a host of vasoactive substances that mediate the "whole body inflammatory response" associated with cardiopulmonary bypass (CPB). Plasma proteins are instantaneously adsorbed onto nonendothelial surfaces; plasma

Cardiopulmonary bypass with a surface-heparinized extracorporeal perfusion system.

ASAIO transactions, 1991
To evaluate the effect of surface heparinization on platelet consumption during cardiopulmonary bypass (CPB) ten pigs were placed on CPB for 3 hours. All pigs were injected with autologous Indium-111 labeled platelets (300-420 uCi) 24 hours prior to CPB and were systemically heparinized prior to cannulation for CPB.

Surface Modified Cardiopulmonary Bypass Circuits: Modifying the Inflammatory Response

Seminars in Cardiothoracic and Vascular Anesthesia, 2002
As a consequence of an aging population demographic, now more than ever, researchers in cardiac surgery must focus on means to improve the methods and technologies related to cardiopulmonary bypass. This review presents a classification of the currently available options for biomaterial modification for cardiopulmonary bypass circuits.

Effect of surface coating on platelet count drop during cardiopulmonary bypass

Perfusion, 1999
This study was designed to investigate the effect of surface coating on platelet count drop during cardiopulmonary bypass (CPB). Sixty patients undergoing open-heart surgery were randomly divided into three groups each receiving a different type of coated hollow-fiber membrane oxygenator.

Towards navigation on the heart surface during coronary arterty bypass grafting

International Journal of Computer Assisted Radiology and Surgery, 2008
Coronary artery bypass grafting (CABG) is the standard treatment for advanced coronary artery diseases. In a preoperative MSCT, both wall plaque formations and resulting optimal anastomotic site are visible to the surgeon. During surgery, the identification of this position on the surface of the heart is of utmost importance for an effective ...

Cardiopulmonary Bypass Circuit Treated With Surface-Modifying Additives: A Clinical Evaluation of Blood Compatibility

The Annals of Thoracic Surgery, 1998
The cardiopulmonary bypass (CPB) circuit induces blood activation and a systemic inflammatory response in cardiac surgical patients. The CPB circuit treated with surface-modifying additive (SMA) has been found to reduce blood activation by in vitro and ex vivo experiments.
