Cardiopulmonary bypass surgery
Current Opinion in Cardiology, 1992New information on cardiopulmonary bypass continues to be produced by investigators from many disciplines. Investigations are related to problems and complications resulting from use of the heart-lung machine. The relationship of perfusion and pressure during bypass in brain, kidney, and other organs is the subject of several reports.

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.

Cardiopulmonary bypass in infants and children
Seminars in Thoracic and Cardiovascular Surgery: Pediatric Cardiac Surgery Annual, 2000Cardiopulmonary bypass (CPB) systems have evolved from futuristic visions of surgical pioneers to a safe and efficient tool in the therapy of treatment of cardiac disorders. There are many significant differences in the physiology between neonates and adult patients. There are currently very few congenital cardiac malformations that cannot be addressed

Ultrafiltration and pediatric cardiopulmonary bypass
Cardiology in the Young, 1993The technique of modified ultrafiltration is a more efficient application of the concept of ultrafiltration during cardiopulmonary bypass. It has been shown to be superior to the conventional method of ultrafiltration.The method can save considerable quantities of donor blood by returning not only the red cells, but also the white cells, platelets, and

CIRCULATORY DYNAMICS OF CARDIOPULMONARY BYPASS
Survey of Anesthesiology, 1963P HYSIOLOGIC and metabolic changes of varying complexity accompany the use of the heart-lung machine in man. These changes relate to many factors, such as the design of the apparatus, the ventilating gas, the pH of the priming blood, the rate and duration of perfusion, the body temperature and the need for and manner of producing cardiac arrest.

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.
