Uncalibrated arterial pulse cardiac output measurements in patients with moderately abnormal left ventricular function.
The aim of the study was to evaluate the accuracy and precision of the Vigileo/FloTrac system (Edwards Lifesciences, Irvine, CA) when compared with the intermittent cardiac output and continuous cardiac output measurements obtained from pulmonary arterial catheters in patients with moderately abnormal left ventricular function undergoing elective coronary artery bypass graft surgery. ⋯ In cardiac surgical patients with moderately abnormal left ventricular function, the Vigileo/FloTrac 2nd generation software sensor device showed mild intraoperative and postoperative agreement when compared with a pulmonary arterial catheter.

Cerebral desaturation during single-lung ventilation is negatively correlated with preoperative respiratory functions.
To evaluate the percent change of cerebral oxygen saturation (SctO(2)) during single-lung ventilation (SLV) and its correlation with preoperative respiratory functions. ⋯ Greater decreases were found in SctO(2) during SLV in patients with better preoperative respiratory function. These findings suggest that intraoperative monitoring during SLV should include not only measurement of SpO(2) and PaO(2) but also SctO(2).

Prophylaxis against atrial fibrillation after cardiac surgery: effective, but not routinely used--a survey of cardiothoracic units in the United kingdom.
To establish whether international recommendations on chemoprophylaxis against postoperative atrial fibrillation in cardiac surgery patients are implemented locally in cardiothoracic units in the United Kingdom; to determine which drugs are being used, how long they are given, and whether outcomes are monitored. ⋯ Chemoprophylaxis against postoperative atrial fibrillation in cardiac surgery patients remains underused, despite its effectiveness and recommendations for its routine use by several international organizations. Departmental guidelines help to ensure routine use, but this survey shows that so far only a minority of cardiothoracic units in the United Kingdom have implemented such guidelines. Awareness of the advantages of routine prophylaxis against atrial fibrillation should be improved and departmental prescribing policies encouraged.
