Which Anesthesia Regimen Is Best to Reduce Morbidity and Mortality in Lung Surgery?: A Multicenter Randomized Controlled Trial

Authors: Beatrice Beck-Schimmer, M.D. et al Anesthesiology 8 2016, Vol.125, 313-321. Background: One-lung ventilation during thoracic surgery is associated with hypoxia–reoxygenation injury in the deflated and subsequently reventilated lung. Numerous studies have reported volatile anesthesia–induced attenuation of inflammatory responses in such scenarios. If the effect also extends to clinical outcome is yet undetermined. We hypothesized that volatile […]

Changes in Brain Resting-state Functional Connectivity Associated with Peripheral Nerve Block: A Pilot Study

Authors: M. Stephen Melton, M.D. et al Anesthesiology 8 2016, Vol.125, 368-377 Background: Limited information exists on the effects of temporary functional deafferentation (TFD) on brain activity after peripheral nerve block (PNB) in healthy humans. Increasingly, resting-state functional connectivity (RSFC) is being used to study brain activity and organization. The purpose of this study was to test […]

Reduced Cancer Risk, Improved Survival With Neuraxial Anesthesia

Neuraxial anesthesia (NA) appears to be associated with improved overall survival (OS) in patients undergoing surgery for tumor resection, particularly in those with colorectal cancer. According to a recent meta-analysis published in Oncotarget(2016;7:15262-15273), the authors identified a correlation between the use of NA and reduced risk for cancer recurrence. The authors found significantly improved OS and […]

Are You Conservative or Liberal?

Fluid Management Strategy for Thoracic Surgery: The optimal range of fluid administration in patients undergoing lung resection surgery has been a controversial topic in anesthesia. There are hazards at both ends of the spectrum: Liberal over-hydration can lead to fluid-induced lung injury, while conservative fluid-management strategies have a risk for organ ischemia. According to a […]

Providing Value-Based Regional Anesthesia: It’s a Matter of Angles

The value of the services that anesthesiologists provide is being examined more closely than ever. Indeed, determining the true value of regional anesthesia can only be done within the context of its many costs, most of which are not monetary. “‘Value’ is the name of the game in medicine these days,” said Brian E. Harrington, […]

Narrow-Spectrum Antibiotics Better for VAP in Trauma Patients

Because traumatically injured patients with early-onset ventilator-associated pneumonia (VAP) are more likely to be sensitive to narrow-spectrum antibiotics than those with late VAP, empirical treatment of early VAP with narrow-spectrum antibiotics is a reasonable choice, a study has found. The results also concluded that broad-spectrum antibiotics should continue to be standard empirical therapy for late […]
