Authors: Chung-Sik Oh, M.D., Ph.D. et al Anesthesiology March 2022, Vol. 136, 448–458. Background The antitumor effects of natural killer cells, helper T cells, and cytotoxic T cells after cancer surgery were reported previously. This study hypothesized that propofol-based anesthesia would have fewer harmful effects on immune cells than volatile anesthetics–based anesthesia during colorectal cancer […]
Read MoreAuthors: Clémence Erlich, M.D. et al Anesthesiology March 2022, Vol. 136, 472–481. Background Perioperative hypersensitivity reactions may be difficult to diagnose during general anesthesia. Postinduction hypotension is the most common sign but is not specific. It was recently suggested that low end-tidal carbon dioxide (ETco2) might be a marker of anaphylaxis (Ring and Messmer grades […]
Read MoreAuthor: Dong Xu Chen, Ph.D. Anesthesiology April 2022, Vol. 136, 662. To the Editor: Silverton et al. nicely described their work with a prototype monitor that measures oxygen partial pressure in the urine at the exit from the urinary catheter. I commend the authors for further emphasizing the association between oxygen partial pressure in the urine and […]

In Reply: We thank Dr. Chen for his interest in our pilot study determining the feasibility of real-time noninvasive urine oxygen measurements in cardiac surgery patients. The device we investigated was a brand-new technology measuring urine oxygen outside of the body at […]
Read MoreAuthors: Madison I. Goldberger, MD et al ASA Monitor January 2022, Vol. 86, 26–27. The COVID-19 global pandemic led to a complete halt in elective surgery so that hospitals could conserve their resources for the onslaught of critically ill patients. Now, as the rate of new infections that require hospitalization declines in the wake of […]

Niraja Rajan M.B.B.S., FAAP, is Associate Professor of Anesthesiology and Perioperative Medicine, Penn State Health, and Medical Director, Hershey Outpatient Surgery Center, Hershey, Pennsylvania. Ambulatory surgery continues to expand rapidly. An increasing number of patients with several comorbidities and advanced age are […]
Read MoreAuthor: Catlin Nalley ASA Monitor February 2021, Vol. 85, 27. Decades ago, sending a patient home the same day he or she underwent surgery was unheard of. However, ongoing advancements in surgical practices as well as improvements in postoperative care have made this the norm. Since it was first proposed in the mid-19th century, ambulatory […]
Read MoreAuthors: Mathieu Blot, M.D., Ph.D. et al Anesthesiology February 2022, Vol. 136, 293–313. Background Mechanical ventilation for pneumonia may contribute to lung injury due to factors that include mitochondrial dysfunction, and mesenchymal stem cells may attenuate injury. This study hypothesized that mechanical ventilation induces immune and mitochondrial dysfunction, with or without pneumococcal pneumonia, that could […]
Read MoreAuthors: Ricardo Alvarez-Jimenez, M.D., Ph.D. et al Anesthesiology February 2022, Vol. 136, 279–292. Background Numerous pharmacokinetic models have been published aiming at more accurate and safer dosing of dexmedetomidine. The vast majority of the developed models underpredict the measured plasma concentrations with respect to the target concentration, especially at plasma concentrations higher than those used […]
Read MoreAuthors: David H. Kim, M.D. et al Anesthesiology March 2022, Vol. 136, 434–447. Background The interscalene nerve block provides analgesia for shoulder surgery. To extend block duration, provide adequate analgesia, and minimize opioid consumption, the use of adjuvants such as dexamethasone as well as the application of perineural liposomal bupivacaine have been proposed. This randomized, […]
