Meta AnalysisSpinal analgesia in cardiac surgery: a meta-analysis of randomized controlled trials.
Controversial results exist on the effects of spinal analgesia in cardiac surgery. The authors conducted a review of randomized studies to show whether there are any advantages in clinically relevant outcomes using spinal analgesia in patients undergoing cardiac surgery. ⋯ This analysis indicated that spinal analgesia does not improve clinically relevant outcomes in patients undergoing cardiac surgery, discouraging further randomized controlled trials on this topic even if changes in techniques, devices, and drugs could modify the outlook of the comparison between spinal and standard anesthesia in this setting.

Comparative StudyAssessment of internal thoracic artery patency with transesophageal echocardiography during coronary artery bypass graft surgery.
The purpose of this study was to evaluate intraoperative transesophageal echocardiography (TEE) for assessing patency of internal thoracic artery grafts. ⋯ The authors concluded that the intraoperative assessment of LITA patency with TEE was a markedly useful and powerful tool for anesthesiologists during CABG surgery.

Comparative StudyComparison of a new cardiac output ultrasound dilution method with thermodilution technique in adult patients under general anesthesia.
The purpose of this study was to investigate the reliability of cardiac output (CO) measured by a new ultrasound dilution method (COud) in comparison with CO by pulmonary artery thermodilution (COtd) in adult patients undergoing surgery. ⋯ COud measurements agreed well with COtd. The results of this study indicated that COud might be interchangeable with conventional COtd in perioperative adult patients.

Randomized Controlled TrialThe association between the initial end-tidal carbon dioxide difference and the lowest arterial oxygen tension value obtained during one-lung anesthesia with propofol or sevoflurane.
The purpose of this study was to examine the correlation between the lowest PaO(2) value recorded during the first 45 minutes of one-lung ventilation (OLV) and the end-tidal CO(2) (ETCO(2)) difference between two-lung ventilation (TLV) and the early phase of OLV. ⋯ The present study indicates that the ETCO(2) difference between TLV and early OLV has an association with impaired oxygenation later during OLV. This would be a simple and clinically convenient predictor of the lowest PaO(2) value likely to be reached during one-lung anesthesia with either propofol or sevoflurane.
