Basal Infusion versus Automated Boluses and a Delayed Start Timer for “Continuous” Sciatic Nerve Blocks after Ambulatory Foot and Ankle Surgery

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 […]

Prophylactic Penehyclidine Inhalation for Prevention of Postoperative Pulmonary Complications in High-risk Patients

Authors: 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 […]

Viscoelastic Hemostatic Assays and Trauma: Are You Ready?

Authors: Thomas E. Grissom, MD, MSIS, FASA, FCCM and Kevin P. Blaine, MD, MPH, FASA ASA Monitor March 2022, Vol. 86, 29–30. 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 […]

Patient Sex and Postoperative Outcomes after Inpatient Intraabdominal Surgery

Authors: Jennifer W. He, B.MSc. et al  Anesthesiology April 2022, Vol. 136, 577–587. 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 […]

Frequency and Risk Factors for Difficult Intubation in Women Undergoing General Anesthesia for Cesarean Delivery

Authors: 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 […]

Intraoperative Hypotension and Acute Kidney Injury, Stroke, and Mortality during and outside Cardiopulmonary Bypass

Authors: Miguel Armengol de la Hoz, M.S. et al  Anesthesiology June 2022, Vol. 136, 927–939. 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 […]

Self-reported Race/Ethnicity and Intraoperative Occult Hypoxemia

Authors: 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 […]

Ketamine Psychedelic and Antinociceptive Effects Are Connected

Authors: 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 […]

Quality Reporting for 2022: Performance Threshold Raised to 75 Points

Author: 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 […]
