conclusions: in the present study, applying positive airway pressure methods (cpap or imv) during cpb was associated with better postoperative abg measurements and (a-a) do2. results: the demographic data were similar in between three groups. graft number, pump time and preoperative abgs were not significantly different. postoperative pao2 were significantly higher in the cpap and imv groups an...

this study evaluates the effect of preoperative increased level of serum creatinine (cr) on early outcomes after coronary artery bypass graft surgery (cabg). 1140 patients who underwent cabg in our center were studied. patients with cr >2.25 mg/dl or preoperative dialysis and who had off-pump operations were excluded. group 1 consisted of 892 patients with normal cr (0.5-1.2 mg/dl) and group 2 ...

Introduction: Coronary artery bypass grafting is a surgical operation that bypasses atherosclerotic coronary vessels and restores blood flow to the ischemic zone of hearts. And two different conventional methods are ON-pump CABG, and Off-pump CABG.  Altogether, the efficacy and safety of these two types of surgical procedures are still under debate. In this study, we aim to com...

With HeartMate II (HMII) implants increasing so has the frequency of device exchange. However, identifying inflow cannula obstruction, pump thrombosis, or outflow obstruction as the mechanism of pump dysfunction can be difficult. Echocardiography, CT angiogram, and cardiac catheterization are not definitive in determining the location of pump failure. Therefore, intraoperative examination is of...

BACKGROUND The aim of the present study was to evaluate and compare postoperative short-term, mid-term and long-term outcomes of coronary artery bypass surgery performed with or without cardiopulmonary bypass in patients with a low European System for Cardiac Operative Risk Evaluation score. METHODS A retrospective analysis of 478 consecutive low risk patients undergoing coronary bypass surge...

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 ...

BACKGROUND On-pump beating-heart coronary artery bypass grafting surgery (CABG) is beneficial due to the elimination of cardioplegic arrest. However, there are few reports regarding its efficacy in chronic hemodialysis patients. This study investigated the potential benefits of on-pump beating-heart CABG in chronic hemodialysis patients. METHODS From January 2002 to January 2010, 186 patients...

Patients with coronary artery disease and left ventricular dysfunction have high mortality with non surgical (medical) treatment. Coronary artery bypass grafting improves survival and the quality of life. Recently, revascularization without cardiopulmonary bypass has been presented as a viable alternative. The aim of this study was to survey the result of coronary artery bypass grafting with of...

Twenty-eight patients undergoing elective coronary artery bypass surgery were allocated randomly to receive either propofol 2 mg kg-1 or an equivalent volume of its vehicle during cardiopulmonary bypass with constant pump flow. Peripheral vascular resistance (PVR) was calculated from perfusion pressure and pump flow. After propofol, PVR decreased from 1767 (SD 415) dyn s cm-5 to a minimum of 12...

Fifty-five patients received total cardiopulmonary support with the disposable Lande-Edwards membrane oxygenator during aortocoronary artery-vein graft operations and other complex open heart operations. Two three meter2 membrane oxygenators were linked in parallel to a standard r o b pump apparatus. (Three 3 meter2 membranes for patients weighing 80 to 103 kg.) Excellent oxygen and carbon diox...
