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.

Comparative StudyPreoperative dispositional optimism correlates with a reduced incidence of postoperative delirium and recovery of postoperative cognitive function in cardiac surgical patients.
To determine if preoperative psychosocial factors including dispositional optimism, perceived social support, and perceived stress correlate with the recovery of postoperative cognition. ⋯ Preoperative dispositional optimism, but not perceived social support, perceived stress, and depression positively correlated with a reduced incidence of postoperative delirium within 5 days and recovery of cognitive performance 1 week after cardiac surgery.

Comparative StudyPerformance comparison of right- and left-sided double-lumen tubes among infrequent users.
To compare performance of right- versus left-sided double-lumen tubes (DLTs) among infrequent users by evaluating the incidence and severity of hypoxemia, hypercapnia, and high airway pressures. ⋯ Left-sided DLTs are perceived to be safer because they may be less prone to malpositioning during lung isolation. However, the supposition that left-sided DLTs are safer than right-sided DLTs when intraoperative hypoxia, hypercapnia, and high airway pressures are used as criteria, even when these tubes are used by infrequent users, is not supported by the data.
