Retraction Of PublicationRetracted: Considerations in patients undergoing implantation of a biventricular pacemaker.
To compare hemodynamics and oxygenation in patients with congestive heart failure and broad QRS complexes before and with biventricular DDD pacing and to report experience with this new procedure. ⋯ There was no acute intraoperative improvement of hemodynamics except increased mean arterial pressure with biventricular pacing. Left ventricular performance seemed to improve with biventricular pacing in some patients. These results might be due to a nonoptimized atrioventricular delay. Postoperatively, atrioventricular delay was individually programmed for each patient by Doppler transmitral flow patterns.

Randomized Controlled Trial Clinical TrialGlucocorticoid effects on the inflammatory and clinical responses to cardiac surgery.
To measure the effects of glucocorticoids on the systemic inflammatory response and clinical recovery after cardiac surgery. ⋯ This study shows significant effects of glucocorticoids on the production of IL-6 and IL-10 in response to cardiac surgery but only minor effects on clinical recovery.

Comparative StudyComparison of continuous, stat, and intermittent cardiac output measurements in patients undergoing minimally invasive direct coronary artery bypass surgery.
To compare intermittent cardiac output (ICO) with continuous cardiac output (CCO) and stat cardiac output (SCO) measurements in patients undergoing minimally invasive direct coronary artery bypass (MIDCAB) surgery. ⋯ Excellent correlation, accuracy, and precision were found among the 3 methods of measuring CO in patients undergoing MIDCAB surgery. Further studies are needed to assess their accuracy in multivessel off-pump coronary artery bypass graft surgery and in patients with poor left ventricular function.

Randomized Controlled Trial Clinical TrialAlfentanil and sufentanil in fast-track anesthesia for coronary artery bypass graft surgery.
To evaluate alfentanil, sufentanil, and the combination of both opioids in patients undergoing cardiac surgery. ⋯ Although the differences among groups regarding extubation time, intensive care unit length of stay, and some hemodynamic data were statistically significant, the differences were clinically small. All 3 anesthetic protocols were shown to be safe and appropriate for patients undergoing elective coronary artery bypass graft surgery and early postoperative tracheal extubation.

Prediction of arterial oxygen tension during one-lung ventilation: analysis of preoperative and intraoperative variables.
To determine whether currently available preoperative and intraoperative variables related to arterial oxygen tension (PaO(2)) can be used as predictors for low PaO(2) during one-lung ventilation (OLV). ⋯ The PaO(2) during OLV can be predicted using routinely available preoperative and intraoperative data. From a clinical point of view, this study failed to identify patients at risk of arterial hypoxemia when OLV is instituted because mainly intraoperative independent variables are involved in the decrease of PaO(2) in this situation.
