Comparative Study Clinical TrialAssessment of cerebral oxygen balance during deep hypothermic circulatory arrest by continuous jugular bulb venous saturation and near-infrared spectroscopy.
The purpose of this study was to compare jugular venous bulb saturation (SjvO(2)) and regional cerebral oximetry (rSO(2)) by near-infrared spectroscopy (NIRS) during procedures with deep hypothermic circulatory arrest (DHCA). ⋯ It was concluded that NIRS does not closely correlate with SjvO(2) in this patient population. Cerebral oximetry measured by NIRS could not replace jugular bulb saturation as an intraoperative marker of adequate metabolic suppression.

Clinical TrialImpact of intraoperative transesophageal echocardiography during noncardiac surgery.
The purpose of this study was to test if parameters measured by intraoperative transesophageal echocardiography (TEE) could be useful to evaluate the hemodynamic status of high-risk cardiovascular patients and if this information was sufficient to make changes in intraoperative management. ⋯ These results strongly suggest that objective measurements made by intraoperative TEE are effective in unveiling relevant clinical findings and useful information in high-risk patients undergoing noncardiac surgery.
