Randomized Controlled Trial Clinical TrialRegional oxygenation and systemic inflammatory response during cardiopulmonary bypass: influence of temperature and blood flow variations.
To evaluate the role of target temperature (28 degrees or 34 degrees C) in cardiac surgery on regional oxygenation during hypothermia and rewarming and systemic inflammatory response. ⋯ During cardiopulmonary bypass, hypothermia at 28 degrees C increases regional and central venous oxygenation better than at 34 degrees C. In contrast, venous oxygenation decreases during rewarming irrespective of the preceding temperature. No significant difference in the systemic inflammatory response associated with target temperature was detected.

Comparative StudyMeasurement of cardiac output after cardiac surgery by a new transesophageal Doppler device.
Assessment of hemodynamics by transesophageal Doppler devices (TDD) may be a less invasive alternative to the pulmonary artery catheter. In contrast to the TDD evaluated so far, a new monitor (HemoSonic100) measures both blood flow velocity and the diameter of the descending aorta. The aim of this study was to assess the accuracy of the cardiac output/index (CO/CI) measured by this device compared with the CO/CI measured by thermodilution. ⋯ The transesophageal Doppler device (HemoSonic100) cannot be recommended as a sole method for monitoring cardiac output in patients after cardiac surgery.

Comparative StudyComparison of thermodilution bolus cardiac output and Doppler cardiac output in the early post-cardiopulmonary bypass period.
To evaluate the accuracy of measuring cardiac output (CO) in the early post-cardiopulmonary bypass (CPB) period by comparing thermodilution with Doppler methods. ⋯ This study adds further support that DCO is a clinically acceptable method to accurately assess the CO in patients even during periods of uneven regional body temperatures as may occur in the early post-CPB period.

Comparative StudyCardiac output measurement after coronary artery bypass grafting using bolus thermodilution, continuous thermodilution, and whole-body impedance cardiography.
To test the feasibility of continuous cardiac output (CO) monitoring with whole-body impedance cardiography after coronary artery bypass grafting and to compare the values obtained with those measured using the bolus and continuous thermodilution methods. ⋯ Agreement between whole-body impedance cardiography and bolus thermodilution is slightly inferior to that between the bolus and continuous thermodilution methods but not to the extent that it hampers the use of whole-body impedance cardiography for the continuous monitoring of CO after coronary artery bypass surgery.

Thoracic epidural analgesia in coronary artery bypass graft surgery: seven years' experience.
To evaluate the risk of neurologic complications caused by an epidural hematoma in a series of patients who had coronary artery bypass graft surgery with cardiopulmonary bypass under combined general and thoracic epidural anesthesia (TEA). ⋯ In this study, some of the benefits previously reported during cardiac surgery under TEA, such as excellent analgesia and early extubation, were confirmed. In addition, the series adds further evidence that adherence to a set of standard safety measures, in this setting, averts the occurrence of symptomatic epidural hematomas.
