Phillip E. Vlisides, M.D. et al Anesthesiology June 2023. Background Perioperative neurocognitive disorders are a major public health issue, though there are no validated neurophysiologic biomarkers that predict cognitive function after surgery. This study tested the hypothesis that preoperative posterior electroencephalographic alpha power, alpha frontal-parietal connectivity, and cerebral oximetry would each correlate with postoperative neurocognitive […]

To the Editor: Although pharmaceutical costs account for approximately 15% of the overall cost of anesthetic care, these expenses are frequently assumed to be due to the choice of anesthetic technique (general vs. regional) or the choice of medications used for anesthetic […]
Read MoreAuthors: Eileen Nguyen, MD, PhD et al Anesthesiology June 2023. Background Pharmacological manipulations directed at the periaqueductal gray have demonstrated the importance of the mu-opioid receptor in modulating reflexive responses to nociception. We hypothesized that a supraspinal pathway centered on neurons in the periaqueductal gray containing the mu-opioid receptor could modulate nociceptive and itch behaviors. […]

Kopman, M.D. Anesthesiology July 2023, Vol. 139, 1–3. “Their observations […] indicate that clinicians who do not see the necessity for quantitative or objective neuromuscular monitoring when reversing residual block with sugammadex need to rethink their position.” In the current issue of Anesthesiology, Bowdle et al. report the results of an observational […]

The preanesthesia evaluation is the process of clinical assessment that precedes the delivery of anesthesia care. It provides the foundation for creating the perioperative anesthesia and pain management plan. The goal is to identify any factors that would prevent the patient from safely having […]
