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.

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.

Cerebral oxygenation in patients with obstructive sleep apnea. Effects of hypoxia at altitude and of acetazolamide.
Sleep-disordered breathing may impair cerebral oxygenation in patients with OSA syndrome, in particular during altitude travel. We studied cerebral tissue oxygenation (CTO) at low and moderate altitude in patients with OSA and evaluated whether acetazolamide improved CTO. ⋯ In patients with OSA staying at altitude, nocturnal cerebral and arterial oxygenation were reduced in association with exacerbated sleep apnea. Acetazolamide partially improved CTO, Spo2, and sleep apnea without impairing the cerebral blood flow response to apneas.

Efficacy of AccuVein to Facilitate Peripheral Intravenous Placement in Adults Presenting to an Emergency Department: A Randomized Clinical Trial.
In the emergency department (ED), intravenous (IV) catheter placement is one of the most frequent interventions and may be a real challenge in some conditions. Improvement of the success rate with new technology represents a great opportunity. This randomized controlled trial aimed to show the superiority of AccuVein to cannulate veins in adults compared to routine care. ⋯ Use of the AccuVein did not improve IV cannulation in nonselected ED patients.
