Randomized Controlled Trial Comparative StudyVolatile agents for cardiac protection in noncardiac surgery: a randomized controlled study.
Volatile anesthetics reduce the risk of myocardial infarction and mortality in coronary artery surgery. Recently, the American College of Cardiology/American Heart Association Guidelines suggested the use of volatile anesthetic agents for the maintenance of general anesthesia during noncardiac surgery in patients at risk for perioperative myocardial ischemia, but no randomized experience to document the cardioprotective effects of these agents exists in this setting. Therefore, the authors performed a prospective, randomized, controlled trial to compare the effects of sevoflurane versus total intravenous anesthesia, in terms of postoperative cardiac troponin I release in patients undergoing noncardiac surgery. ⋯ In the authors' experience, patients undergoing noncardiac surgery did not benefit from anesthesia based on halogenated anesthetics. Further studies are necessary to evaluate the cardioprotective effects of volatile agents in noncardiac surgery.

Randomized Controlled Trial Comparative StudyComparison of the analgesic effects of continuous extrapleural block and continuous epidural block after video-assisted thoracoscopic surgery.
A prospective, randomized, open study. The regional technique used was not blinded. ⋯ Although this study did not show the superiority of continuous extrapleural block relative to continuous epidural in VATS patients, the results suggest that both methods provided effective analgesia with a relatively small dose of rescue morphine. Although the analgesic effects of these techniques were comparable, extrapleural block has the advantage of safety and precise placement of the catheter and can be considered an alternative to epidural block in VATS patients.

A pilot study of patients with clinically severe obesity undergoing laparoscopic surgery: evidence for impaired cardiac performance.
Given the propensity for heart disease in obese patients, the authors investigated the effects of pneumoperitoneum on cardiac performance. ⋯ The study data revealed that surgical pneumoperitoneum used in patients with clinically severe obesity resulted in the deterioration of cardiac performance including the development of new-onset DD. These patients, despite their relative young age and without a history of heart failure or coronary artery disease, displayed a cardiovascular profile during laparoscopic surgery similar to that seen in patients with significant heart disease.
