Comparative StudyPostoperative hyperthermia following off-pump versus on-pump coronary artery bypass surgery.
Hyperthermia is common in the first 24 hours following coronary artery bypass graft surgery (CABG) with cardiopulmonary bypass (CPB). An inflammatory response to CPB is often implicated in the pathophysiology of this fever. Unlike CABG with CPB, the temperature pattern after off-pump CABG (OPCAB), where CPB is avoided, has not yet been described. The purpose of this study was to describe the postoperative temperature pattern following OPCAB and to compare it with that following on-pump cardiac surgery. ⋯ Off-pump CABG surgery patients experience less hyperthermia compared with on-pump CABG patients. The reasons for a lower incidence and severity of hyperthermia after OPCAB surgery are not known, but may be related to a reduced inflammatory response.

Comparative StudyAntifibrinolytic use and bleeding during surgery on the descending thoracic aorta: a multivariate analysis.
The purpose of this study was to determine the potential benefit of antifibrinolytic (AF) therapy in improving hemostasis in descending aortic surgery in which extracorporeal distal perfusion is used. ⋯ The authors could not show a beneficial effect of AF therapy on bleeding and transfusion, although current practice shows that this therapy continues to be used. Because heterogeneity of patient population exists and bias cannot be completely excluded, a prospective investigation evaluating efficacy and safety in this population is warranted.

Comparative StudyXenon and the inflammatory response to cardiopulmonary bypass in the rat.
The purpose of this study was to investigate the effect of xenon on the inflammatory response to cardiopulmonary bypass. ⋯ Xenon appears to have no effect on the inflammatory response to cardiopulmonary bypass, making its previously described neuroprotective effect during cardiopulmonary bypass likely independent of any inflammation modulation.
