Randomized Controlled Trial Comparative StudyHigh-frequency jet ventilation as an alternative method compared to conventional one-lung ventilation using double-lumen tubes during minimally invasive coronary artery bypass graft surgery.
To optimize the conditions for the surgeon during minimally invasive direct coronary artery bypass (MIDCAB) and totally endoscopic coronary artery bypass (TECAB) procedures, one-lung ventilation (OLV) is required using double-lumen tubes (DLT). This prospective study was designed to compare high-frequency jet ventilation (HFJV) of both lungs with the conventional method of OLV via DLT. ⋯ HFJV in MIDCAB or TECAB procedures appears to be a feasible alternative to OLV using a DLT, although study in a larger population is required.

Comparative StudyComparison of spectral entropy and bispectral index electroencephalography in coronary artery bypass graft surgery.
The study's aim was to compare response entropy (RE) and state entropy (SE) with bispectral index (BIS) electroencephalography (EEG) as an alternative cerebral monitoring tool in patients scheduled for coronary artery bypass graft surgery. ⋯ RE and SE are comparable with the BIS but showed significantly less interference from f-EMG and superior resistance against artifacts. Thus, spectral entropy is more suitable than the BIS during propofol-remifentanil anesthesia in cardiac surgery patients.

Meta Analysis Comparative StudyEpidural analgesia improves outcome in cardiac surgery: a meta-analysis of randomized controlled trials.
The authors conducted a review of randomized studies to determine whether there were any advantages for clinically relevant outcomes by adding epidural analgesia in patients undergoing cardiac surgery under general anesthesia. ⋯ This analysis suggested that epidural analgesia on top of general anesthesia reduced the incidence of perioperative acute renal failure, the time on mechanical ventilation, and the composite endpoint of mortality and myocardial infarction in patients undergoing cardiac surgery.

Randomized Controlled Trial Comparative StudyModifiable and nonmodifiable risk factors for postoperative delirium after cardiac surgery with cardiopulmonary bypass.
Postoperative delirium after cardiac surgery is associated with increased morbidity and mortality as well as prolonged stay in both the intensive care unit and the hospital. The authors sought to identify modifiable risk factors associated with the development of postoperative delirium in elderly patients after elective cardiac surgery in order to be able to design follow-up studies aimed at the prevention of delirium by optimizing perioperative management. ⋯ In this post hoc analysis, larger doses of fentanyl administered intraoperatively and longer duration of mechanical ventilation were associated with postoperative delirium in the elderly after cardiac surgery. Prospective randomized trials should be performed to test the hypotheses that a reduced dose of fentanyl administered intraoperatively, the use of a different opioid, or weaning protocols aimed at early extubation prevent delirium in these patients.
