Endovascular and Open Repairs of Abdominal Aortic Aneurysms Have Similar Long-Term Mortality Rates

After endovascular repair of abdominal aortic aneurysms, mortality rises over time but doesn’t surpass that associated with open repair, a New England Journal of Medicine study suggests. From more than 125,000 Medicare beneficiaries who underwent either procedure, about 40,000 in each procedure group were matched according to propensity to undergo endovascular repair. Periprocedural mortality was 1.6% with […]

Psychiatric Comorbidity Is Associated Prospectively with Diminished Opioid Analgesia and Increased Opioid Misuse in Patients with Chronic Low Back Pain

Anesthesiology published on 7 2015 Authors: Ajay D. Wasan MD, M.Sc et al Background: Opioids are frequently prescribed for chronic low back pain (CLBP), but there are little prospective data on which patient subgroups may benefit. Psychiatric comorbidity, such as high levels of depression and anxiety symptoms (termed comorbid negative affect [NA]), is a common presentation and may […]

A Randomized Crossover Study Comparing a Novel Needle Guidance Technology for Simulated Internal Jugular Vein Cannulation

Anesthesiology published on 7 2015 Authors: David B Auyong MD et al Background: Despite ultrasound guidance for central line placement, complications persist, as exact needle location is often difficult to confirm with standard two-dimension ultrasound. A novel real-time needle guidance technology has recently become available (eZono, Germany) that tracks the needle during insertion. This randomized, blinded, crossover study examined […]

Ability of the Nociception Level, a Multiparameter Composite of Autonomic Signals, to Detect Noxious Stimuli during Propofol–Remifentanil Anesthesia

Anesthesiology Published on 7 2015. Authors: Chris H. Martini MD et al Background: A novel multidimensional index of nociception, the nociception level (NoL) index, derived from the nonlinear composite of heart rate (HR), HR variability, amplitude of the photoplethysmogram, skin conductance, fluctuations in skin conductance, and their time derivatives, was used to assess nociception during anesthesia. Methods: […]

Discharge Readiness after Tricompartment Knee Arthroplasty: Adductor Canal versus Femoral Continuous Nerve Blocks—A Dual-center, Randomized Trial

Anesthesiology 8 2015, Vol.123, 444-456 Authors: Anthony T. Machi MD et al Background: The authors conducted a randomized, controlled, parallel-arm, superiority study to test the hypothesis that a continuous adductor canal block decreases the time to attain four discharge criteria compared with a continuous femoral nerve block after tricompartment knee arthroplasty. Methods: Subjects undergoing tricompartment knee arthroplasty were randomized […]
