Surgeon Variation in Perioperative Opioid Prescribing and Medium- or Long-term Opioid Utilization after Total Knee Arthroplasty

Authors: Xi Cen, Ph.D. et al  Anesthesiology June 2022. Background Whether a particular surgeon’s opioid prescribing behavior is associated with prolonged postoperative opioid use is unknown. This study tested the hypothesis that the patients of surgeons with a higher propensity to prescribe opioids are more likely to utilize opioids long-term postoperatively. Methods The study identified […]

Dynamic Obstruction due to Unfurling of Spirals in a Flexometallic Tube

Authors: Shwethashri Kondavagilu Ramaprasannakumar, M.D., D.M. et al Anesthesiology July 2022, Vol. 137, 79–80. Flexometallic tubes are kink-resistant and extensively used in neurosurgeries. The manufacturers of flexometallic tubes recommend single usage. In low-income countries, due to the cost restraints, flexometallic tubes are commonly reused after ethylene oxide sterilization. With this technique, flexometallic tubes are effectively […]

Carbon Footprint of Anesthesia: Comment

Authors: Quentin Gobert, M.D., D.E.S.A.R.; Lyndia Dernis, M.D., D.E.S.A.R. Anesthesiology July 2022, Vol. 137, 118–119. To the Editor: We read with interest the article by Mc Gain et al. presenting the comparative carbon footprint of two general and regional anesthesia techniques. As the authors point out, the results cannot be systematically extrapolated to other countries because of the […]

Carbon Footprint of Anesthesia: Comment

Authors: Mitchell H. Tsai, M.D., M.M.M., F.A.S.A., F.A.A.C.D. et al  Anesthesiology July 2022, Vol. 137, 119–120. To the Editor: Using life cycle assessments, McGain et al.  account for the carbon footprint of general, regional, and combined anesthesia techniques for total joint replacements in Australia. With the accounting of carbon emissions, we applaud the authors for demonstrating that the […]

Carbon Footprint of Anesthesia: Comment

Authors: Kristopher M. Schroeder, M.D., F.A.S.A. et al Anesthesiology July 2022, Vol. 137, 122. To the Editor: We read with great interest the recent article by McGain et al.1  that quantified the carbon footprint associated with the provision of spinal anesthesia and general anesthesia for total knee arthroplasty. This type of encompassing evaluation is valuable as it is […]

Constrained Functional Connectivity Dynamics in Pediatric Surgical Patients Undergoing General Anesthesia

Authors: Michael P. Puglia, II, M.D., Ph.D. et al  Anesthesiology July 2022, Vol. 137, 28–40. Background Functional connectivity in cortical networks is thought to be important for consciousness and can be disrupted during the anesthetized state. Recent work in adults has revealed dynamic connectivity patterns during stable general anesthesia, but whether similar connectivity state transitions occur […]

Targeting Depth of Anesthesia to Prevent Delirium: Comment

Authors: Xinglong Xiong, M.D. et al  Anesthesiology June 2022, Vol. 136, 1045–1046. To the Editor: Brown et al.1  nicely described their work comparing spinal anesthesia with targeted sedation based on Bispectral Index values compared with general anesthesia (masked Bispectral Index) and the outcome of delirium. Intraoperative hypotension has been associated with delirium.2,3  The adjusted hazard ratio associated with a […]

Targeting Depth of Anesthesia to Prevent Delirium: Reply

Authors: Charles H. Brown, IV, M.D., M.H.S. Charles W. Hogue, M.D. Anesthesiology June 2022, Vol. 136, 1047–1048. In Reply: We thank Drs. Xiong et al.1  and Carella and Bonhomme2  for their comments regarding the shaping anesthetic techniques to reduce post-operative delirium (SHARP) study.3  We agree that evaluating intraoperative hypotension as a potentially moderating factor in the SHARP trial would be interesting.
