Oxidative stress and inflammatory response increase during coronary artery bypass grafting with extracorporeal circulation.
INTRODUCTION Thiobarbituric acid-reactive substance is a marker of oxidative stress and has cytotoxic and genotoxic actions. C- reactive protein is used to evaluate the acute phase of inflammatory response. OBJECTIVES To assess the thiobarbituric acid-reactive substance and C-reactive protein levels during extracorporeal circulation in patients submitted to cardiopulmonary bypass. METHODS T...
متن کاملTracheal Chondrosarcoma Excised With Extracorporeal Circulation
Introduction: Tracheal chondrosarcoma (TCS) is a rare malignancy, with only 19 cases described in the literature to date. Case presentation: Herein, we presented the third-largest TCS with such an airway compromise that neither orotracheal intubation nor jet ventilation or even tracheostomy was possible. So, extracorporeal circulation was needed to excise the tumor in a one-stage procedure. Th...
متن کاملHuman neutrophil degranulation during extracorporeal circulation.
Cardiopulmonary bypass, especially when prolonged, may result in hemostatic failure and pulmonary dysfunction, which has been attributed to changes in platelets and leukocytes, respectively. It has been well documented that contact of blood with synthetic surfaces causes platelet activation. In this report, we explore mechanisms of the activation of neutrophils during simulated in vitro extraco...
متن کاملStudies on cardiac lymph during extracorporeal circulation.
Cardiac lymph in dogs was used to study the metabolism and state of the myocardium during extracorporeal circulation and various additional procedures. Changes in the flow characteristics, cdor and pH of lymph were noted, and corresponding samples of cardiac lymph and coronary sinus blood were analyzed for lactate concenlmtion. Ventricular fibrillation led to higher lactate levek when compared ...
متن کاملStudies on blood viscosity during extracorporeal circulation.
Blood viscosity was studied during extracorporeal circulation by means of a cone in cone viscometer. This rotational viscometer provides sixteen kinds of shear rate, ranging from 0.05 to 250.2 sec-1 • Merits and demerits of the equipment were described comparing with the capillary viscometer. In experimental study it was well demonstrated that the whole blood viscosity showed the shear rate dep...
