The hemostatic dysfunction induced by cardiopulmonary bypass is due, in part, to a platelet dysfunction evidenced by a postoperative extension of the bleeding time; it leads to increased postoperative blood loss and morbidity. This study, which was c

Hematologic Changes During and Following Cardiopulmonary Bypass and Their Relationship to Non-Surgical Blood Loss. 1. Platelet Function and the Bleeding Time

Autor: Shukri F. Khuri, Samar N. Assousa, Gina Ragno, Trevoc C. Axford, Miguel Josa

The changes in platelet parameters and the bleeding time during and following cardiopulmonary bypass (CPB) and their relationships to non-surgical blood loss following the administration of protamine were investigated in 85 adult male patients underg

Publikováno v: Journal of Surgical Research. 42:247-256

The composition of the ideal cardioplegic solution is controversial. Blood cardioplegia is an attractive alternative to standard crystalloid solutions, though its superiority in preserving myocardial metabolism has not been demonstrated. Using a new

The Effects of Complement Activation During Cardiopulmonary Bypass

Autor: Kenneth G. Warner, Shukri F. Khuri, Samar N. Assousa, Francis D. Moore, C. R. Valeri

Publikováno v: Annals of Surgery. 208:95-103

Complement activation was examined prospectively in 100 cardiopulmonary bypass (CPB) patients. Plasma C3a desArg (C3a) increased (cannulation: 234 +/- 33 ng/mL; 20 minutes on CPB: 622 +/- 51; 2 hours after CPB: 1143 +/- 109, p less than 0.0001). C3a

Significance of the transmural diminution in regional hydrogen ion production after repeated coronary artery occlusions

Autor: Samar N. Assousa, Samer Y. Siouffi, William A. Marston, Assad J. Saad, Satish C. Sharma, Philip T. Lavin, Shukri F. Khuri, Kenneth G. Warner, Michael D. Butler

Publikováno v: Circulation Research. 64:616-628

Previous studies have revealed that the regional accumulation of ischemic metabolites including hydrogen ion (H+) and PCO2 diminish after repeated occlusions. We postulated that this diminution reflects a blunted metabolic response that is related to

Structural and metabolic correlates of cell injury in the hypertrophied myocardium during valve replacement

Autor: Marcel Seiler, Robert A. Kloner, Karen M. Dalecki-Chipperfield, Kenneth G. Warner, Seok S. Lee, Shukri F. Khuri, Ernest M. Barsamian, Michael D. Butler, Samar N. Assousa, Miguel Josa

Publikováno v: The Journal of Thoracic and Cardiovascular Surgery. 93:741-754

To characterize the ultrastructural and metabolic changes occurring in the hypertrophied ventricle during cardiac operations in man, we studied 36 patients with valvular heart disease undergoing valve replacement, during which multiple doses of cold

Regional changes in myocardial acid production during ischemic arrest: a comparison of sanguineous and asanguineous cardioplegia

Autor: Peter C. Gherardi, Miguel Josa, Samar N. Assousa, Samer Y. Siouffi, Kenneth G. Warner, Shukri F. Khuri, Ernest M. Barsamian, Michael D. Butler, Assad J. Saad

Publikováno v: The Annals of thoracic surgery. 45(1)

Regional differences in myocardial acid production have not been characterized during administration of either asanguineous or sanguineous cardioplegia. To investigate this, miniature glass pH electrodes were placed in the right ventricular (RV) myoc
