The transcutaneous technique of measuring carbon dioxide tension (tcPCO2) was studied in 30 adult neurosurgery patients undergoing nitrous oxide-enflurane or nitrous oxide-fentanyl anesthesia to determine the relationship between tcPCO2 and PaCO2. tcPCO2 was an accurate (r = 0.9) and clinically useful trend indicator of PaCO2. The ability to detect trends(More)
UNLABELLED Diagnostic interpretation of intraoperative transesophageal echocardiography (TEE) examinations may vary, particularly when the echocardiographer is also the anesthesiologist. We therefore evaluated the concordance of TEE interpretation as part of a process of continuous quality improvement (CQI). Ten cardiac anesthesiologists participating in a(More)
The transcutaneous technique of measuring PO2 (tcPO2) was studied in 30 adults with normal cardiovascular function undergoing nitrous oxide-enflurane or nitrous oxide-fentanyl anesthesia to determine the relationship between tcPO2 and PaO2. The tcPO2 was an accurate and clinically useful trend indicator of PaO2 (r = 0.9; p less than 0.0001). The ability to(More)
Because Starling's equation contains four factors that theoretically influence fluid movement across the pulmonary capillary bed, we prospectively examined the relationship between the plasma colloid oncotic pressure (PCOP) minus the mean pulmonary artery occlusion pressure (PAOP) (the only two presently available clinically for measurement) and pulmonary(More)
OBJECTIVE To assess the effects of heart rate, right ventricular systolic performance (ejection fraction), chamber dimensions, and flow rate (cardiac index) on the reproducibility of algorithm-derived triplicate thermodilution right ventricular ejection fraction measurements. DESIGN Prospective study; combined hemodynamic and echocardiographic clinical(More)
We evaluated a combined transcutaneous oxygen and carbon dioxide (tcPO2 and tcPO2) monitor in 33 adult surgical patients in an intensive care unit. Surgical procedures included cardiothoracic, general, vascular, and orthopedic operations. Ninety-three paired, transcutaneous values were compared with simultaneously determined arterial blood gas measurements.(More)
We evaluated our experience with 846 consecutive transesophageal echocardiography (TEE) intraoperative monitoring procedures performed between November 1989 and July 1991. TEE frequency was 36 +/- 11 per month (range 16-55) and represented 69.8% of cardiac valve surgery cases, 40.2% of coronary artery bypass graft cases, and 2.2% of total operative(More)
