Authors: John J. Finneran, IV, M.D. et al Anesthesiology June 2022, Vol. 136, 970–982. Background The common technique using a basal infusion for an ambulatory continuous peripheral nerve blocks frequently results in exhaustion of the local anesthetic reservoir before resolution of surgical pain. This study was designed to improve and prolong analgesia by delaying initiation using […]
Read MoreAuthors: Ting Yan, M.D. et al Anesthesiology April 2022, Vol. 136, 551–566. Background Postoperative pulmonary complications are common. Aging and respiratory disease provoke airway hyperresponsiveness, high-risk surgery induces diaphragmatic dysfunction, and general anesthesia contributes to atelectasis and peripheral airway injury. This study therefore tested the hypothesis that inhalation of penehyclidine, a long-acting muscarinic antagonist, reduces the […]

Uncontrolled hemorrhage requiring emergent surgery after major trauma continues to be a contributor to perioperative death (Intensive Care Med 2019;45:709-11). While most hemorrhage deaths occur before injured patients reach the hospital, advancement in medical management […]

Background Intraabdominal surgeries are frequently performed procedures that lead to a high volume of unplanned readmissions and postoperative complications. Patient sex may be a determinant of adverse outcomes in this population, possibly due to differences in biology or care delivery, but it is […]
Read MoreAuthors: Sharon C. Reale, M.D. et al Anesthesiology May 2022, Vol. 136, 697–708. Background Estimates for the incidence of difficult intubation in the obstetric population vary widely, although previous studies reporting rates of difficult intubation in obstetrics are older and limited by smaller samples. The goals of this study were to provide a contemporary estimate of […]

Background In cardiac surgery, the association between hypotension during specific intraoperative phases or vasopressor-inotropes with adverse outcomes remains unclear. This study’s hypothesis was that intraoperative hypotension duration throughout the surgery or when separated into hypotension during and outside cardiopulmonary bypass […]
Read MoreAuthors: Garrett W. Burnett, M.D. et al Anesthesiology May 2022, Vol. 136, 688–696. Background Pulse oximetry is ubiquitous in anesthesia and is generally a reliable noninvasive measure of arterial oxygen saturation. Concerns regarding the impact of skin pigmentation and race/ethnicity on the accuracy of pulse oximeter accuracy exist. The authors hypothesized a greater prevalence of occult […]
Read MoreAuthors: Erik Olofsen, Ph.D. et al Anesthesiology May 2022, Vol. 136, 792–801. Background Ketamine produces potent analgesia combined with psychedelic effects. It has been suggested that these two effects are associated and possibly that analgesia is generated by ketamine-induced dissociation. The authors performed a post hoc analysis of previously published data to quantify the pharmacodynamic properties of […]
Read MoreAuthor: Matthew T. Popovich, PhD ASA Monitor March 2022, Vol. 86, 37. In the first quarter of each year, anesthesiologists and their groups encounter a number of burdens for federal quality reporting. These burdens include choosing quality measures, updating measure specifications, and modifying workflows to accommodate new quality measure data capture. For 2022, ASA was able […]
Read MoreAuthor: Barbara M. Rogers, MD, MBOE, FASA ASA Monitor March 2022, Vol. 86, 26. Editor’s note: The ASA Monitor is pleased to introduce Dr. Gearhead, a new recurring column developed to provide anesthesiologists with a strong working knowledge of the latest patient wearables, implantable devices, and other medical technologies sure to be encountered in the OR or preoperative […]
