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 […]

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 novel real-time needle guidance technology has recently become available (eZono, Germany) that tracks the needle during insertion. This randomized, blinded, crossover study examined […]

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: […]

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 […]
