Randomized Controlled Trial Clinical TrialThe value of preoperative pharmacologic stress testing before vascular surgery using ACC/AHA guidelines: a prospective, randomized trial.
To evaluate the validity of preoperative cardiac stress testing using clinical predictors from the American College of Cardiology/American Heart Association Guidelines on Perioperative Evaluation before Noncardiac Surgery in patients undergoing vascular surgery. ⋯ In this small prospective, randomized study evaluating the validity of preoperative cardiac stress testing using ACC/AHA Guidelines before major vascular surgery, preoperative cardiac stress testing offered no incremental value for determining postoperative adverse cardiac outcomes. Larger randomized clinical trials are needed to confirm these findings.

Comparative StudyA comparison of CardioQ and thermodilution cardiac output during off-pump coronary artery surgery.
To compare CardioQ esophageal Doppler cardiac output and thermodilution cardiac output during off-pump coronary artery bypass surgery. ⋯ Because of the wide limits of agreement and the large interpatient differences in both bias and precision, the CardioQ esophageal Doppler cardiac output cannot currently be recommended as an alternative to thermodilution cardiac output during off-pump coronary artery bypass surgery.

Randomized Controlled Trial Clinical TrialPyruvate-enhanced cardioprotection during surgery with cardiopulmonary bypass.
To determine whether pyruvate-fortified cardioplegia solution provides cardioprotection superior to lactate-based cardioplegia solutions in patients undergoing elective coronary revascularization, with specific attention to post-surgical recovery of left ventricular performance as well as biochemical markers of ischemic injury. ⋯ Pyruvate-fortified cardioplegia mitigated myocardial injury during coronary artery bypass surgery and facilitated postsurgical recovery of cardiac performance. Thus, pyruvate-enhanced cardioplegia may provide cardioprotection superior to lactate-based solutions during surgical cardiac arrest.

Clinical TrialPropofol-ketamine mixture for anesthesia in pediatric patients undergoing cardiac catheterization.
To evaluate the safety of a propofol-ketamine mixture to induce and maintain anesthesia in spontaneously breathing pediatric patents during cardiac catheterization. ⋯ The propofol-ketamine mixture is a safe, practical alternative for general anesthesia in pediatric patients undergoing cardiac catheterization.
