Platelets and cardiopulmonary bypass
Perfusion, 1998Exposure of blood to an extracorporeal circulation, such as CPB, causes a variety of physiological responses. Haematological derangements are just one of many potential dangers to the patient who undergoes CPB. The paradox of CPB-related problems with the haematological system is that there are some factors tipping the balance towards a bleeding ...

Normothermic cardiopulmonary bypass
Journal of Cardiothoracic and Vascular Anesthesia, 1997H YPOTHERMIA and cardiac surgery have been closely linked since Dr F. John Lewis performed the first successful "open heart" surgery under direct vision using vena caval inflow occlusion and generalized hypothermia accomplished by surface cooling in 1952.

The platelet in cardiopulmonary bypass
The Annals of Thoracic Surgery, 1998Platelets are the smallest of the blood cells and are known to be activated during cardiopulmonary bypass. They play a role in many associated complications. Both quantitative and qualitative platelet defects have been demonstrated, resulting in microvascular hemorrhage and thromboembolism.

Thromboelastography and Cardiopulmonary Bypass
Seminars in Thrombosis and Hemostasis, 2012The TEG tracks postoperative hemorrhage after CPB and is useful in guiding therapy. Its ability to characterize the overall interaction of all procoagulant participants in a final outcome (clot strength) is unique. Much work in the future is needed to establish the particular applications for TEG monitoring in CPB ...

Hyponatremia and Cardiopulmonary Bypass
Journal of Cardiothoracic and Vascular Anesthesia, 2007A 68-year-old man presented with recurrent angina after coronary rtery bypass graft (CABG) surgery. He also was noted to have severe yponatremia. He initially presented at age 46 with unstable angina and nderwent 3-vessel CABG (saphenous vein grafts to the left anterior escending, right coronary, and obtuse marginal arteries).

Cardiopulmonary bypass: new strategies for weaning from cardiopulmonary bypass
Current Opinion in Anaesthesiology, 1999This review focuses on weaning from cardiopulmonary bypass, a very critical time for patients and anaesthetists and frequently requiring major therapeutic effort. Few novel strategies for weaning have been described recently. Most drugs or approaches described during the review period are already well established.

Update on cardiopulmonary bypass
Current Opinion in Anaesthesiology, 2001Investigations into cardiopulmonary bypass continue to refine knowledge and clinical practice. Recent investigations have emphasized neurological complications, introducing the possibility of genetic predisposition as a risk factor. Appropriate flows, pressures, and hematocrit levels during cardiopulmonary bypass continue to create controversy. Whereas

Biocompatibility in cardiopulmonary bypass
Journal of Cardiothoracic and Vascular Anesthesia, 1997Recent advances in surgical techniques and perfusion technology allow cardiac operations to be performed routinely with low mortality rates. However, patients undergoing cardiac operations with cardiopulmonary bypass (CPB) are still associated with bleeding disorders, thrombotic complications, massive fluid shifts, and the activation of blood ...

Required flow rates for cardiopulmonary bypass depend on the patient’s body surface area and temperature. At 37°C, flow of 2.2 L/m2 per minute is required for adequate perfusion. Oxygen consumption is reduced, however, by 50 per cent for every 10°C drop in temperature. At 20°C, a 30-minute period of circulatory arrest can be safely tolerated.
