Cardiopulmonary bypass (CPB) provides a bloodless field for cardiac surgery. It incorporates an extracorporeal circuit to provide physiological support in which venous blood is drained to a reservoir, oxygenated and sent back to the body using a pump. Team effort between surgeon, perfusionist and anaesthesiologist is paramount for the successful use of CPB. However, it also has its share of com...

We experienced a case of aortic valve replacement after previous coronary artery bypass grafting with patent bypass grafts. Based on the retrosternal anatomy assessed by preoperative angiography and thoracic computed tomography, aortic valve replacement was performed through a median resternotomy. After careful dissection of the right side of the heart and the ascending aorta, cardiopulmonary b...

conclusions radical nephrectomy and tumor thrombectomy by intrapericardial control without cardiopulmonary bypass and hypothermic circulatory arrest is a safe and effective procedure that can avoid serious intra- and postoperative complications while providing acceptable cancer-control and mortality results. case presentation the records of six patients with supradiaphragmatic tumor thrombi, wh...

background: postoperative pulmonary dysfunction is one of the most frequent complications after cardiac surgery and it is believed to result from the use of cardiopulmonary bypass (cpb). in this study, we investigated the effect of low tidal volume ventilation during cpb on postoperative gas exchange and lung mechanics. methods: this prospective randomized study included 100 patients undergoing...

postoperative vasoplegic syndrome (vs) is characterized by low systemic vascular resistance, normal or elevated cardiac output, and poor response to volume expansion. the incidence of vs after cardiac surgery requiring cardiopulmonary bypass is about 20%. sometimes, vs becomes refractory and initial treatments do not work, rendering treatment a great challenge. in this study, we describe a youn...

Background and Purpose We evaluated the utility of blood flow velocity measurements by transcranial Doppler ultrasonography as a tool to indirectly measure cerebral perfusion during cardiopulmonary bypass. Methods We simultaneously measured blood flow velocity in the middle cerebral artery and physiological variables in 18 patients undergoing cardiac surgery under hypothermic cardiopulmonary by...

At the end of the Second World War, the devastation of many cities in Europe, combined with the problems of reconstruction and loss of financial support, had brought European medical research to a halt. On the other hand, in the United States the war brought about an enormous amount of scientific research through the development of nuclear weapons, the mass production of penicillin, early compu...
