Randomized Controlled Trial Clinical TrialThermodilution cardiac output measurement during simultaneous volume infusion through the venous infusion port of the pulmonary artery catheter.
To determine the effect on thermodilution cardiac output (TDCO) measurements of continuous volume infusion through the right atrial venous infusion port of the pulmonary artery catheter. ⋯ Rapid continuous infusion of fluid through the venous infusion port of the pulmonary artery catheter significantly limits the accuracy of simultaneous TDCO measurements. Optimally, TDCO measurements should be avoided during rapid volume infusion.

Randomized Controlled Trial Clinical TrialEffect of pump flow rate on cerebral blood flow during hypothermic cardiopulmonary bypass in adults.
The purpose of this study was to examine the effect of cardiopulmonary bypass flow rate on cerebral blood flow and cerebral metabolic rate for oxygen during hypothermic (27 degrees C) cardiopulmonary bypass. ⋯ Brain oxygenation is well maintained at lower than conventional pump flow levels during CPB. There may be practical advantages to reduced flows during hypothermia, and flow reductions do not appear to adversely affect cerebral blood flow or metabolism.

Early extubation after mitral valve surgery: a target-controlled infusion of propofol and low-dose sufentanil.
In the current study, the use of a target-controlled infusion of low-dose propofol was combined with a continuous infusion of sufentanil for patients undergoing mitral valve surgery. The purpose of the study was to evaluate the hemodynamic stability, the time to awakening and spontaneous ventilation, and the feasibility in an early extubation setting of a total intravenous anesthetic technique. ⋯ The simplicity of the method with only one change in infusion rate is a major advantage. The technique permits predictable recovery and return to spontaneous ventilation in all patients. Its use in patients entering early extubation protocols is appealing for its reproducibility, simplicity, and safety.

Comparative StudyContinuous intraoperative noninvasive cardiac output monitoring using a new thoracic bioimpedance device.
To compare a new noninvasive bioimpedance device with the standard thermodilution method during the intraoperative period in high-risk patients undergoing oncological surgery. ⋯ This new impedance device is a safe, reliable, clinically acceptable alternative to the invasive thermodilution method in the operating room environment.

Comparative StudyRespiratory outcomes with early extubation after coronary artery bypass surgery.
Aortocoronary bypass surgery has undergone recent changes, promoting the concept of "fast tracking," in which patients are extubated and discharged postoperatively at an accelerated pace compared with previous historic patterns. Postoperative respiratory function and complications have not been previously studied in patients selected for "fast tracking." ⋯ Differences in chest radiographs in the late extubation group at the time of extubation may be related to greater use of fluids or increased airway obstruction. The rationale of early extubation is based on cost minimization to decrease hospital duration. This article suggests that respiratory physiological outcomes are not worsened in patients who are extubated and discharged early after elective aortocoronary bypass surgery.
