Randomized Controlled Trial Comparative Study Clinical TrialEffects of positive end-expiratory pressure on ventilatory and oxygenation parameters during pressure-controlled one-lung ventilation.
The purpose of this study was to investigate the effects of PEEP on oxygenation and airway pressures during PCV-OLV. ⋯ During OLV, PCV with a low level of PEEP leads to improved oxygenation with lower airway pressures.

Comparative StudyHypercoagulability affecting early vein graft patency does not exist after off-pump coronary artery bypass.
Hypercoagulability may compromise the patency of bypass grafts. The authors hypothesized that perioperative in vitro platelet responses to varying agonists (eg, thrombin, platelet activating factor, collagen, adenosine diphosphate) correlate with early graft thrombosis after off-pump coronary artery bypass grafting (OPCAB). ⋯ OPCAB is not associated with a significant activation in postoperative platelet function. This study suggests that if hypercoagulability exists after OPCAB, it is not involved in the pathogenesis of arterial thrombotic events such as early bypass graft failure.

Comparative StudyResource utilization in on- and off-pump coronary artery surgery: factors influencing postoperative length of stay--an experience of 1,746 consecutive patients undergoing fast-track cardiac anesthesia.
The purpose of the present investigation was to examine factors influencing resource utilization in patients undergoing on-pump coronary artery bypass graft and off-pump coronary artery bypass (OPCAB) graft surgery at a major university hospital. The resources examined were time to extubation, packed red blood cell (PRBC) transfusion, intensive care length of stay (ICULOS), preoperative and postoperative length of stay (PLOS), and total length of stay (LOS). ⋯ The authors found that patients undergoing on-pump CABG have significantly longer time to tracheal extubation, increased blood use, longer ICULOS, PLOS, and total LOS and higher in-hospital mortality, which would translate into significant differences in the expenses associated with these 2 surgical approaches to coronary surgery.

Randomized Controlled Trial Comparative Study Clinical TrialRemifentanil use in children undergoing congenital heart surgery for left-to-right shunt lesions.
The authors compared the effects of remifentanil with fentanyl on the hemodynamic and respiratory variables in children with left-to-right shunting and pulmonary hypertension. ⋯ There were no clinically important differences in hemodynamic and respiratory measurements intraoperatively and during the initial 24 hours postoperatively between fentanyl and remifentanil in pediatric patients undergoing surgical repair of defects with left-to-right shunts.
