The intraoperative assessment of ascending aortic atheroma: epiaortic imaging is superior to both transesophageal echocardiography and direct palpation.
To determine the optimal method for detecting ascending aortic atheroma intraoperatively by comparing manual palpation by the operating surgeon, intraoperative transesophageal echocardiography, and epiaortic ultrasound (linear and phased-array imaging); and to assess risk factors for severe aortic atheroma. ⋯ Age older than 70 years and hypertension are significant risk factors for severe ascending aortic atheroma. Intraoperative detection of ascending aortic atheroma is best achieved by epiaortic ultrasound with either a linear or phased array transducer. Transesophageal echocardiography is an insensitive technique for evaluation of mid and distal ascending aortic atheroma and, therefore, of little value in guiding surgical manipulations such as cross-clamping.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA randomized multicenter double-blind comparison of urapidil and ketanserin in hypertensive patients after coronary artery surgery.
To compare the hemodynamic responses, safety, and efficacy of urapidil and ketanserin in hypertensive patients after coronary artery surgery. ⋯ In contrast to ketanserin, urapidil did not increase heart rate. Urapidil was more effective in lowering arterial blood pressure than ketanserin. However, one third of the patients treated with urapidil developed hypotension after 60 minutes of continuous infusion.

Randomized Controlled Trial Clinical TrialForced-air warming is no more effective than conventional methods for raising postoperative core temperature after cardiac surgery.
To determine whether postoperative forced-air warming of cardiac bypass patients in the intensive care unit (ICU) results in faster rate of warming and improved outcomes compared with more conventional ICU warming methods. ⋯ There is no evidence from this study to warrant use of forced-air warming devices for the care of postoperative cardiac surgical patients in the ICU.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of isoflurane and midazolam as hypnotic supplementation to moderately high-dose fentanyl during coronary artery bypass grafting: effects on systemic hemodynamics and early postoperative recovery profile.
The aim of this study was to compare isoflurane and midazolam as hypnotic adjuncts to moderately high-dose fentanyl during coronary artery bypass grafting (CABG) with regard to perioperative hemodynamics and early postoperative recovery profile. ⋯ Midazolam supplementation to fentanyl required more frequent antihypertensive escape during the pre-CPB period than isoflurane. However, more frequent cessation of isoflurane caused by hypotension was needed in the post-CPB period. No difference in awakening and ICU discharge was found.
