Authors: Francesco Zarantonello, M.D. et al Anesthesiology Newly Published on July 2022. Background The mechanisms underlying oxygenation improvement after prone positioning in COVID-19 acute respiratory distress syndrome have not been fully elucidated yet. The authors hypothesized that the oxygenation increase with prone positioning is secondary to the improvement of ventilation-perfusion matching. Methods In a series of […]

Background Accurate estimation of surgical transfusion risk is essential for efficient allocation of blood bank resources and for other aspects of anesthetic planning. This study hypothesized that a machine learning model incorporating both surgery- and patient-specific variables would outperform the traditional approach […]

Background Mechanical power during ventilation estimates the energy delivered to the respiratory system through integrating inspiratory pressures, tidal volume, and respiratory rate into a single value. It has been linked to lung injury and mortality in the acute respiratory distress syndrome, but little […]
Read MoreAuthors: Mike Charlesworth and Andrew Klein #theanesthesiablog Major airway complications are rare and the best evidence on which we base current practice comes from NAP4, which was published in 2011. This new contribution from Cumberworth et al. used similar methods within six hospitals to see what has changed and highlight key areas for further training and development. […]

Figure: Opportunities for quality improvement in non-operating room anesthetizing locations. NORA=non-operating room anesthesia; M&M=mortality and morbidity. Communication failures contribute to adverse events, morbidity, and mortality and may be complicated by both interprofessional and interdisciplinary dynamics within the procedural setting (J […]
Read MoreAuthor: Sarah G. Bodin, MD, FASA ASA Monitor June 2022, Vol. 86, 30. Today I reviewed another “low-risk clearance” checkbox note from an advanced practice registered nurse, for a topical cataract case, under monitored anesthesia care. Prior to the patient’s topical cataract extraction, my healthy 64-year-old patient had visited her primary care physician to be cleared […]
Read MoreСаrdiac Anesthesiologist June 03, 2022 Adjunctive Therapy Warming Bleeding patients with core or intermediate zone temperatures less than 35°C will benefit from warming efforts, both passive (warm ambient temperature, adequate body coverings, low-ventilator fresh gas flows, airway heat and humidity exchangers) and active (heated humidifiers, warmed intravenous fluids, forced-air convective warming blankets). All too often, […]
Read MoreAuthors: Dylan Irvine, BScH et al Anesthesia Patient Safety Foundation Newsletter Volume 37, No. 2 • June 2022 Introduction As of 2018, an estimated 9.5% of the United States adult population were cannabis users.1 This percentage has likely continued to increase with the use of both recreational and medicinal cannabis in the United States. The use of […]
Read MoreAuthors: Mike Charlesworth and Andrew Klein #theanesthesiablog Despite several published guidelines recommending the use of peri-operative checklists, there is a paucity in reporting team adherence to checklist use. This new 5-year audit from Fuchs et al. aimed to report the adherence of anaesthesia providers to an anaesthesia pre-induction checklist. The checklist was to be undertaken before […]
Read MoreAuthors: 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 […]
