A prospective study was conducted to evaluate the trans-oxygenator pressure gradient across three different hollow-fibre membrane oxygenators during routine cardiopulmonary bypass (CPB). Sixty consecutive open-heart surgery patients were randomly divided into three groups each receiving a different model of membrane oxygenator. Inlet and outlet pressures,(More)
With the push to get patients through the system in five days, most patients undergoing nonemergency coronary artery bypass grafting (CABG) are being "fast-tracked'. Using this anaesthetic regimen appears to keep patients less anaesthetized (light) during cardiopulmonary bypass (CPB) than when using our previous regimen. This is manifested by higher mean(More)
An investigation was conducted to determine whether adding albumin to the prime of the cardiopulmonary bypass circuit had any effect on postoperative weight gain. Patients undergoing non-emergency myocardial revascularization for coronary artery disease were divided into two groups. Group I (albumin) received 250 ml of 5% human albumin in their pump prime,(More)
An investigation was conducted to compare several variables of off-pump coronary artery bypass (OPCAB) procedures with those using cardiopulmonary bypass (CPB) for myocardial revascularization by two surgeons. The patients were divided into four groups: group 1 patients received CPB for their myocardial revascularization performed by surgeon A; group 2(More)
Adenosine is an endogenous nucleotide and a breakdown product of adenosine triphosphate. Adenosine has been proposed as a mediator of the ischaemic preconditioning phenomenon. Ischaemic reperfusion injury incurred during and following cardiopulmonary bypass contributes to depressed myocardial function after cardiac surgery. It is believed that administering(More)
An investigation was conducted to evaluate the effect that surface coating of the hollow-fiber membrane oxygenator had on circulating platelet count drop during cardiopulmonary bypass (CPB). Sixty patients undergoing non-emergency myocardial revascularization for coronary artery disease were randomly divided into two groups. Group one (n = 32) received the(More)
