Randomized Controlled Trial
Remifentanil during cardiac surgery is associated with chronic thoracic pain 1 yr after sternotomy.
Chronic thoracic pain after cardiac surgery is a serious condition affecting many patients. The aim of this study was to identify predictors for chronic thoracic pain after sternotomy in cardiac surgery patients by analysing patient and perioperative characteristics. ⋯ In this follow-up study in cardiac surgery patients, intraoperative remifentanil was predictive for chronic thoracic pain in a dose-dependent manner. Randomized studies designed to evaluate the influence of intraoperative remifentanil on chronic thoracic pain are needed to confirm these results.

Randomized Controlled Trial Comparative Study
Lung isolation in the morbidly obese patient: a comparison of a left-sided double-lumen tracheal tube with the Arndt® wire-guided blocker.
Obese patients are at risk of complications during airway management including difficult tracheal intubation. There are no reports regarding the ease of intubation or efficiency of lung collapse with the use of lung isolation devices for the morbidly obese patient. We conducted a prospective, randomized study in morbidly obese patients undergoing one-lung ventilation. We compared the effectiveness and ease of placement of a left-sided double-lumen tube and the Arndt(®) blocker. ⋯ There is no overall advantage of one device over the other during intubation of the morbidly obese patient.

This observational study was designed to evaluate the reliability and precision of a new digital photoplethysmographic device (Nexfin, BMEYE B.V., Amsterdam, The Netherlands) for continuous and non-invasive assessment of arterial pressure and cardiac output. ⋯ The Nexfin device is safe, convenient, and reliable in measuring continuous non-invasive arterial pressure but not interchangeable with transpulmonary thermodilution to monitor CI.
