background following coronary artery bypass graft (cabg), patients are at high risk (3.2%-8.3%) for developing hospital-acquired pneumonia (hap) with mortality rate of 24% to 50%. some of routine features in patients undergoing cabg are similar to clinical criteria of center of disease control (cdc) for diagnosis of pneumonia. this may lead to over-diagnosis of pneumonia in these patients. obje...

background: dialysis patients frequently have coronary artery disease but are regarded as high risk patients for coronary artery bypass grafting (cabg). methods: between february 2002 and september 2006, seventeen dialysis-dependent patients underwent isolated cabg at our center. cabg was performed under cardiopulmonary bypass (cpb) for all the patients. all cases had been maintained on hemodia...

background: the cardioprotective effect of ischemic preconditioning has been known for many years. since the temporary ischemia in the heart may cause lethal cardiac effects, the idea of creating ischemia in organs far from the heart such as limbs was raised as remote ischemic preconditioning (ripc). we hypothesized that the extension of ripc has more cardioprotective effect in patients undergo...

background and aim: postoperative hemorrhage is a common complication following coronary artery bypass graft (cabg) surgery. warming the patient may be effective on postoperative hemorrhage and blood transfusion. the main objective of this study was to determine the effect of postoperative active warming of the patient on hemorrhage and blood transfusion after off-pump cabg surgery. methods: th...

Sixteen patients undergoing coronary revascularization requiring cardiopulmonary bypass received remifentanil 2 micrograms kg-1 or 5 micrograms kg-1 by infusion over 1 min after sternotomy but before commencing cardiopulmonary bypass, during hypothermic cardiopulmonary bypass and during cardiopulmonary bypass after rewarming. Hypothermic cardiopulmonary bypass reduced the clearance of remifenta...

ethods: Male Sprague–Dawley rats were divided into four groups (each n 6): ham group, cardiopulmonary bypass group, and two N-acetylcysteine–treated ardiopulmonary bypass groups (bolus doses of 200 and 500 mg/kg in cardiopulonary bypass prime). Blood samples were collected at the beginning of cardioulmonary bypass, at the cessation of cardiopulmonary bypass, and at 2 and 12 ostoperative hours. ...

The main purpose of the off-pump coronary artery bypass surgery is to reduce morbidity and mortality due cardiopulmonary bypass. However, even though many studies have shown that off-pump coronary artery bypass is feasible and provides hospital morbidity and mortality similar to the on-pump coronary artery bypass graft surgery, probably better in some aspects, its long-term results have been qu...

Introduction: As off pump Coronary artery bypass grafting surgery (CABG) is a developing method in coronary cardiac surgery, most surgeons are anxious about the danger of emergency crash conversion. In this observational study we tried to show the rate and outcome of conversion . Material and methods: In this descriptive study about 477 coronary off-pump CABG patients were operated in Ghaem hos...

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...
