Sustained Total All-Region (STAR) perfusion for Norwood reconstruction with complex intracardiac repair
Perfusion (United Kingdom) - Tập 36 Số 5 - Trang 532-534 - 2021
Neel K. Prabhu, Joseph W. Turek, Nicholas D. Andersen
We present the case of a newborn with complex congenital heart disease who was treated with a neonatal Norwood operation and total anomalous pulmonary venous return repair. During the Norwood reconstruction, a novel technique was utilized to perfuse the head, lower body, and heart continuously to minimize ischemic injury.
A novel method of measuring cardiac output in infants following extracorporeal procedures: preliminary validation in a swine model
Perfusion (United Kingdom) - Tập 20 Số 6 - Trang 323-327 - 2005
Richard W. Melchior, Edward Darling, Bryan Terry, Gordy Gunst, Bruce Searles
In infants, technologies for obtaining rapid, quantified measurements of cardiac output (CO) following weaning from cardiopulmonary bypass (CPB) or extracorporeal membrane oxygenation are not readily available. A new technique to measure CO based on ultrasound velocity dilution is described. It utilizes reusable probes placed on the extracorporeal circuit that permits convenient measurement of CO ... hiện toàn bộ
Comparison of the use of minimized cardiopulmonary bypass with conventional techniques on the incidence of retinal microemboli during aortic valve replacement surgery
Perfusion (United Kingdom) - Tập 26 Số 6 - Trang 479-486 - 2011
Riikka Rimpiläinen, Nina Hautala, J.K. Koskenkari, Jussi Rimpiläinen, P P Ohtonen, Pirjo Mustonen, H-M Surcel, E-R Savolainen, Martti Mosorin, TI Ala-Kokko, Tatu Juvonen
Objectives: Minimized cardiopulmonary bypass (MCPB) circuits have been shown to reduce cerebral and retinal microembolisation during coronary artery bypass graft (CABG) surgery compared to conventional CPB (CCPB) circuits. Our aim was to evaluate whether the reduction of microembolisation is sustained in aortic valve surgery, as well as to evaluate the effects of MCPB on inflammatory, endothelial,... hiện toàn bộ
Expression of soluble endothelial adhesion molecules in clinical cardiopulmonary bypass
Perfusion (United Kingdom) - Tập 13 Số 5 - Trang 314-321 - 1998
Joseph Galea, Naomi Rebuck, Adam Finn, A. Manché, Neil Moat
Soluble endothelial adhesion molecule expression in clinical cardiopulmonary bypass (CPB) was investigated. Neutrophil-mediated endothelial injury plays an important role in CPB-induced organ dysfunction. The adhesion of neutrophil to the endothelium is central to this process. It has been well documented that CPB induces neutrophil activation and changes in neutrophil adhesion molecule expression... hiện toàn bộ
A recovery model of partial cardiopulmonary bypass in the rat
Perfusion (United Kingdom) - Tập 16 Số 3 - Trang 215-220 - 2001
Olivier Fabre, Rachid Zegdi, André Vincentelli, Michèle Cambillaud, Alain Prat, Alain Carpentier, Jean‐Noël Fabiani
This study was undertaken to develop a recovery model of cardiopulmonary bypass (CPB) in rats. Twenty male Wistar rats (475-550 g) were anaesthetized, mechanically ventilated and the femoral vessels cannulated. The extracorporeal circulation circuit comprised a roller pump, a venous reservoir and a modified Capiox 308 paediatric membrane oxygenator. Priming consisted of 20 ml of fresh homologous b... hiện toàn bộ
Systemic inflammatory response and the splanchnic bed in cardiopulmonary bypass

A comparison study of haemolysis production in three contemporary centrifugal pumps
Perfusion (United Kingdom) - Tập 29 Số 5 - Trang 411-416 - 2014
Steve Bottrell, Martin R. Bennett, S Augustin, Clarke A. Thuys, Bradley Schultz, Allison M. Horton, Stephen Horton
One challenge in providing extracorporeal circulation is to supply optimal flow while minimising adverse effects, such as haemolysis. To determine if the recent generation constrained vortex pumps with their inherent design improvements would lead to reduced red cell trauma, we undertook a study comparing three devices. Utilizing a simulated short-term ventricular assist circuit primed with whole ... hiện toàn bộ
Impact of cardiopulmonary bypass on peripheral tissue metabolism and microvascular blood flow
Perfusion (United Kingdom) - Tập 23 Số 6 - Trang 339-346 - 2008
Jiří Manďák, Marek Pojar, Norbert Cibicek, Vladimír Lonský, Vladimír Palička, D Kakrdová, J Nedvı́dková, J Kubíček, Pavel Živný
The aim of this study was to monitor and compare the changes in metabolism and blood flow in the skeletal muscles during cardiac operations performed with cardiopulmonary bypass (CPB) and operations without CPB (off-pump) by means of interstitial microdialysis (Figure 1). Surgical revascularization, coronary artery bypass grafting (CABG), was performed in 40 patients randomized to two groups. Twen... hiện toàn bộ
Red blood cell transfusion volume and mortality among patients receiving extracorporeal membrane oxygenation
Perfusion (United Kingdom) - Tập 28 Số 1 - Trang 54-60 - 2013
Andrew Smith, DC Hardison, B. Berly Bridges, Pietsch Jb
Background: Red blood cell (RBC) transfusion is used in the critically ill with low hemoglobin concentrations to optimize oxygen utilization and delivery imbalance. Data suggest that RBC transfusion is also independently associated with significant morbidity. We seek to characterize RBC transfusion volumes among patients receiving extracorporeal membrane oxygenation (ECMO) support and test the hyp... hiện toàn bộ
Mini extracorporeal circuit for coronary artery bypass grafting: initial clinical and biochemical results
Perfusion (United Kingdom) - Tập 19 Số 4 - Trang 239-246 - 2004
David Breen, Wim B. Gerritsen, Frans G. Waanders, Fred J.L.M. Haas
Background: The new concept of mini-extracorporeal circulation (MECC) for coronary artery bypass grafts (MCABG) consists of minimal priming volume, a heparin-coated closed circuit, a centrifugal pump, active drainage, blood cardioplegia and a cell-saving device. The potential organ protective effect of this technique during CABG is unknown. Initial clinical outcomes, oxidative stress, alveolar shu... hiện toàn bộ
