Randomized Controlled Trial Multicenter StudySupplemental postoperative oxygen does not reduce surgical site infection and major healing-related complications from bariatric surgery in morbidly obese patients: a randomized, blinded trial.
12-16h of post-op supplemental O2 (80%) does not reduce wound infection or complication in the morbidly obese undergoing gastric bypass.

Randomized Controlled Trial Comparative StudyAccuracy of the Composite Variability Index as a Measure of the Balance Between Nociception and Antinociception During Anesthesia.
The Composite Variability Index (CVI), derived from the electroencephalogram, was developed to assess the antinociception-nociception balance, whereas the Bispectral Index (BIS) was developed to assess the hypnotic state during anesthesia. We studied the relationships between these indices, level of hypnosis (BIS level), and antinociception (predicted remifentanil effect-site concentrations, CeREMI) before and after stimulation. Also, we measured their association with movement in response to a noxious stimulus. ⋯ CVI appears to correlate with somatic responses to noxious stimuli. However, unstimulated CVI depends more on hypnotic drug effect than on opioid concentration.

Randomized Controlled TrialA Simulator Study of Tube Exchange with Three Different Designs of Double-Lumen Tubes.
We sought to determine whether the design of 3 different double-lumen endobronchial tubes (DLT) (Rusch, Mallinckrodt, Fuji) has an effect on the ease of placement over an airway exchange catheter (AEC) using a video laryngoscope. ⋯ The Fuji-Phycon DLT was easier to pass over an AEC in this simulator trial and warrants consideration in patients with difficult airways who require 1-lung ventilation.

Randomized Controlled Trial Comparative StudyEffect of Local Anesthetic Dilution on the Onset Time and Duration of Double-Injection Sciatic Nerve Block: A Prospective, Randomized, Blinded Evaluation.
Neither speed of onset or duration of Labat sciatic block is influenced by volume or LA concentration when the total dose of mepivacaine is constant.
