Randomized Controlled Trial Comparative Study Clinical TrialA prospective comparison of three heat preservation methods for patients undergoing hypothermic cardiopulmonary bypass.
To prospectively compare 3 methods of body heat preservation in patients undergoing surgery requiring the use of hypothermic cardiopulmonary bypass (CPB). ⋯ This study suggests that there is no statistically significant disparity in the effectiveness of these 3 intraoperative heat preservation methods. Ease of use and cost-effectiveness should guide the choice of warming method post-CPB.

Randomized Controlled Trial Clinical TrialProtective ventilation attenuates postoperative pulmonary dysfunction in patients undergoing cardiopulmonary bypass.
To ascertain if protective ventilation can attenuate the damaging postoperative pulmonary effects of cardiopulmonary bypass (increases in airway pressure, decreases in lung compliance, and increases in shunt). ⋯ Data indicate that protective ventilation decreases pulmonary damage caused by mechanical ventilation in normal and abnormal lungs. The results of this investigation indicate that protective ventilation may also help attenuate the postoperative pulmonary dysfunction (increases in airway pressure, decreases in lung compliance, and increases in shunt) commonly seen in patients after exposure to cardiopulmonary bypass.

Postcardiopulmonary bypass hypoxemia: a prospective study on incidence, risk factors, and clinical significance.
To evaluate the clinical significance of low arterial oxygen tension-inspired oxygen concentration (PaO2-FIO2) ratio, as a measure of hypoxemia, in the early period after cardiac surgery with cardiopulmonary bypass (CPB); and to evaluate the preoperative, intraoperative, and postoperative factors contributing to the development of hypoxemia within the first 24 hours after cardiac surgery with CPB. ⋯ This study shows that despite improvements in the technique of CPB, hypoxemia depicted by low PaO2-FIO2 ratios is common in patients after CPB. It is short lived, however, and has minimal effect on the postoperative clinical course of these patients.

Postoperative atrial tachyarrhythmias in patients undergoing coronary artery bypass graft surgery without cardiopulmonary bypass: a role for intraoperative magnesium supplementation.
To determine if intraoperative magnesium supplementation would be associated with a reduction in postoperative atrial tachyarrhythmias (POAT) in patients undergoing coronary artery bypass grafting (CABG) surgery without cardiopulmonary bypass (off-pump CABG surgery). ⋯ Intraoperative magnesium supplementation is associated with a decrease in POAT after off-pump CABG surgery. The combination of a beta-blocker and magnesium may reduce POAT further. It is recommended that intraoperative magnesium supplementation be part of the care of patients undergoing off-pump CABG surgery.

Randomized Controlled Trial Clinical TrialLidocaine for prevention of reperfusion ventricular fibrillation after release of aortic cross-clamping.
To determine the efficacy of a bolus of lidocaine administered by way of the pump before releasing the aortic cross-clamp (ACC) in preventing the occurrence of reperfusion ventricular fibrillation. ⋯ The results suggest that a bolus of 100 mg of lidocaine administered 2 minutes before release of the ACC can safely decrease the incidence of reperfusion ventricular fibrillation and is associated with better hemodynamics after weaning from cardiopulmonary bypass.
