Dexmedetomidine Does Not Reduce Atrial Fibrillation After Lung Cancer Surgery.
To evaluate whether the use of intraoperative dexmedetomidine (DEX) during lung cancer surgery may reduce the incidence of postoperative atrial fibrillation (POAF). ⋯ These results were similar to those published elsewhere on POAF incidence and risk factors. This study could not confirm the hypothesis that the intraoperative use of DEX is associated with a reduced rate of POAF after thoracic surgery for lung cancer.

The Effect of Intraoperative 6% Balanced Hydroxyethyl Starch (130/0.4) During Cardiac Surgery on Transfusion Requirements.
To compare transfusion requirements in adult cardiac surgery patients when balanced hydroxyethyl starches (HES) (130/0.4) or balanced crystalloids is used for pump prime and intraoperative fluid therapy. ⋯ HES patients required more transfusions, owing to greater hemodilution, HES-induced clotting disturbances, and bleeding.

Multidisciplinary Approach to Transvenous Lead Extraction: A Single Center's Experience.
To evaluate the success and complication rates of a single center's multidisciplinary approach to transvenous lead extraction. ⋯ Transvenous lead extraction generally is a safe procedure, but not without complications. A multidisciplinary approach involving cardiac surgery, electrophysiology, and cardiac anesthesiology allows for successful management and the ability to rapidly manage major complications.

Elevated Arterial Lactate Concentrations Early After Coronary Artery Bypass Grafting Are Associated With Increased Anaerobic Metabolism in Skeletal Muscle.
To assess the effect of coronary artery bypass grafting with cardiopulmonary bypass on muscle perfusion, oxygen extraction, and lactate release during postoperative rest and exercise. ⋯ The patients had elevated anaerobic metabolism in skeletal muscle after surgery to compensate for anemia. Lactate was released from the leg into the general circulation during postoperative rest and exercise. The postoperatively reduced hemoglobin concentration of 11.4 mg/dL (10.6-12.3) resulted in increased anaerobic metabolism and release of lactate from skeletal muscle. The authors concluded that coronary artery bypass grafting patients are susceptible to anaerobic metabolism even with maintained peripheral blood flow.
