Centrifugal Pumping: The Patient Outcome Benefits Following Coronary Artery Bypass Surgery
The increased use of the centrifugal pump during coronary artery bypass surgery has been based primarily on theoretical data related to patient safety. There is minimal evidence suggesting improved outcome when compared to the traditional roller pump technology. We prospectively randomized 200 patients undergoing elective coronary artery bypass grafting into centrifugal pump (100 patients) and ...
متن کاملUse of centrifugal pump and extracorporeal membrane oxygenation as cardiopulmonary support in pediatric cardiovascular surgery.
BACKGROUND Extracorporeal membrane oxygenation is a well-documented resuscitation method in patients with severe hemodynamic and/or respiratory impairment. OBJECTIVE To describe several aspects related to the use of extracorporeal membrane oxygenation in a pediatric heart center and determine its immediate and late outcomes. METHODS Between October 2005 and January 2007, 10 patients who wer...
متن کاملTypes of centrifugal separations
One way of improving the resolution of particles by size is to minimize the difference in RCF between the top and bottom of the sample. Practically this is achieved by layering the sample as a narrow band over a continuous density gradient. This is called rate-zonal gradient (sedimentation velocity) centrifugation; the conditions are chosen such that ρρ always remains greater than ρl. In a cont...
متن کاملProinflammatory mediator response in coronary bypass surgery using a centrifugal or a roller pump.
Major surgery, trauma, and infection induce a proinflammatory mediator response which, if excessive, may cause tissue injury. The response was measured during elective coronary bypass surgery when a centrifugal pump or a roller pump, differing in their basic working principles, was used for extracorporeal circulation (ECC). Eight patients were perfused with a centrifugal pump and eight patients...
متن کاملCentrifugal pump and reduction of neurological risk in adult cardiac surgery.
This study was performed to assess if the kind of pump used for CPB (roller vs. centrifugal) can influence neurological outcomes of adult cardiac surgery patients. Between 1994 and 1998, 3438 patients underwent coronary and/or valve surgery at our hospital; of these, 1805 (52.5%) underwent surgery with the use of a centrifugal pump, and 1633 (47.5%) were operated with a roller pump. The effect ...
