Randomized Controlled Trial Clinical TrialEffects of amiodarone and thoracic epidural analgesia on atrial fibrillation after coronary artery bypass grafting.
This study was designed to assess the effects of a perioperative dosing regimen of amiodarone administration, high thoracic epidural anesthesia (TEA), or a combination of the 2 regimens on atrial fibrillation (AF) after coronary artery bypass grafting (CABG). ⋯ The perioperative amiodarone regimen used in this study was effective in reducing the incidence of AF after CABG while TEA was not.

Comparative Study Clinical TrialOff-pump versus on-pump coronary artery bypass surgery and postoperative pulmonary dysfunction.
To investigate how off-pump coronary artery bypass grafting (CABG) affects postoperative pulmonary function when compared with on-pump CABG. ⋯ Off-pump CABG does not confer major protection from postoperative pulmonary dysfunction compared with CABG surgery with CPB. Strategies for minimizing pulmonary impairment after CABG surgery should be directed to factors other than the use of CPB.

Alterations of mesenteric blood flow after cardiopulmonary bypass: a Doppler sonographic study.
Mesenteric ischemia after cardiopulmonary bypass is a serious complication associated with high mortality. It was the aim of this study to investigate mesenteric blood flow with the help of Doppler sonography in asymptomatic patients before and after cardiopulmonary bypass and cardiac surgery. ⋯ The postoperative changes in the flow velocities and the increases of the resistive and pulsatility index are indications of rigidity of the mesenteric vascular bed and decreased mesenteric perfusion after cardiopulmonary bypass.

Predictors of atrial fibrillation after off-pump coronary artery bypass graft surgery.
Atrial fibrillation is the most common complication after coronary artery bypass graft surgery. This arrhythmia may lead to hemodynamic compromise, prolonged hospitalization, and increased risk for cerebral thromboembolism. Older age is the only variable consistently associated with the development of postoperative atrial fibrillation; however, no strong predictive model exists. The purpose of this study was to identify perioperative characteristics associated with new-onset atrial fibrillation in patients undergoing off-pump coronary artery bypass grafting. ⋯ Despite the less invasive approach, the incidence of postoperative atrial fibrillation is high after off-pump coronary artery bypass grafting. Older age, grafting of the ramus medianus, and a redo operation were predictors of new-onset postoperative atrial fibrillation. It is possible that left atrial stretching with heart dislocation during revascularization of the lateral wall could lead to postoperative atrial fibrillation.
