Detection of air bubbles in the blood is important for various medical treatments that use Extracorporeal Blood Circuits (ECBC), such as hemodialysis, hemofiltration and cardio-pulmonary bypass. Therefore a reliable air bubble detector is needed. This study presents the design of a new fault tolerant air bubble detector. Triple Modular Redundancy (TMR) method is used on the sensor section. A vo...

Methods In total, 259 patients were enrolled, after the exclusion of patients with severe pre-existing renal insufficiency (defined as a eGFR< 15 ml/min). As part of a broader study, urine and blood samples were obtained immediately before initiation of cardio-pulmonary bypass. Patients were subsequently retrospectively divided into 2 groups, AKI (n=84) and non-AKI (n=175). This subdivision was...

A separation between the aortic media and annulus fibrosus causes a rare cardiac abnormality called sinus of Valsalva aneurysm (SVA) that may be congenital or acquired. It is more prevalent in the right coronary sinus (65%-85%) but it has been seen rarely in non-coronary (10%-30%) or Left coronary sinus (<5%). The most common complication is rupture of the Aneurysm. We present an 80-year-old ma...

Vasopressin is a hormone from posterior pituitary. It is an octapeptide referred often as arginine vasopressin and antidiuretic hormone. It is emerging as an important advance in the treatment of variety of shock states. The current interest is for the use of ventricular fibrillation, sepsis and cardio pulmonary bypass. The pressor actions are complex and not unAddress requests for reprints to:...

A 69-year-old male, who underwent cardio-pulmonary bypass surgery, required biventricular support using the Abiomed. The patient subsequently developed a consumptive coagulopathy. The thromboelastograph was used to administer NovoSeven and guide allogenic transfusions to achieve a hematocrit of greater than 30% and a platelet count greater than 100,000 per microL. Disseminated intravascular coa...

A 57-year-old female patient was admitted with dys-pnoea. With two-dimensional (2D) transthoracic and trans-oesophageal echocardiography, a left-atrial myxoma of 3.1 Â 4 cm was diagnosed. Coronary angiography demonstrated that the myxoma had been neo-vascularised originating from the circumflex artery (Fig. 1). The tumour was resected successfully with cardiopulmonary bypass (Fig. 2). Fig. 1. I...

BACKGROUND Excessive myocardial necrosis following coronary artery bypass grafting is associated with adverse outcome. The present study was designed to assess the extent of myocardial injury after conventional coronary artery bypass grafting with cardio pulmonary bypass (ONCAB) compared with off-pump coronary artery bypass (OPCAB). METHODS Measurements of serum cardiac troponin T (TnT) were ...

Non-Insulin Dependent Diabetes Mellitus (NIDDM) is a common disease entity in patients with Coronary Artery Disease (CAD). Diabetic Ketoacidosis (DKA) is not only one of the major complications of Diabetes Mellitus but also a significant challenging clinical entity for the patients undergoing any elective or emergency surgery. Coronary Artery Bypass Grafting (CABG) being done in a patient with ...
