Randomized Controlled Trial Comparative StudyDifferent anesthetic techniques associated with different incidences of chronic post-thoracotomy pain: low-dose remifentanil plus presurgical epidural analgesia is preferable to high-dose remifentanil with postsurgical epidural analgesia.
To investigate the relationships between 2 anesthetic techniques, or the extent of allodynia around the surgical wound, and the occurrence of chronic post-thoracotomy pain. ⋯ High-dose remifentanil (0.14-0.26 microg/kg/min) without epidural analgesia during surgery is associated with a large area of allodynia around the wound. These patients develop a much higher incidence of chronic pain than those receiving low-dose remifentanil with epidural analgesia during surgery.

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.
