AUTHORS: Guay, Christian S. MD et al Anesthesia & Analgesia 136(1):p 140-151, January 2023. BACKGROUND: Delirium is an acute syndrome characterized by inattention, disorganized thinking, and an altered level of consciousness. A reliable biomarker for tracking delirium does not exist, but oscillations in the electroencephalogram (EEG) could address this need. We evaluated whether the frequencies of […]

BACKGROUND: Delirium is the most common postoperative complication in older adults, though anesthesiologist awareness of delirium prevention guidelines—and associated practice trends—remains unknown. METHODS: This was a convergent mixed-methods study, which simultaneously analyzed quantitative and qualitative data to determine delirium guideline awareness among anesthesiologists […]

BACKGROUND: Increased body mass index (BMI) is considered as an important factor that affects the need for total knee and hip arthroplasty (TKA/THA) and the rate of perioperative complications. Previous investigations have not fully established the relationship of BMI and perioperative […]

BACKGROUND: A single laboratory range for all individuals may fail to take into account underlying physiologic differences based on sex and genetic factors. We hypothesized that laboratory distributions differ based on self-reported sex and ethnicity and that ranges stratified by these factors […]

BACKGROUND: Inhaled halogenated anesthetics are responsible for half of operating room total greenhouse gas emissions. Sustainable anesthesia groups were set up in 4 Lyon, France, university hospitals (Hospices Civils de Lyon) in January 2018 and have supported a specific information campaign about the […]

BACKGROUND: Norepinephrine is effective in preventing spinal hypotension during cesarean birth; however, an optimal regimen has not been determined. We hypothesized that an initial bolus of norepinephrine improves efficacy of spinal hypotension prophylaxis beyond continuous norepinephrine alone. METHODS: In this double-blind, controlled study, […]
Read MoreAUTHORS: Lee, Linden O. MD et al Anesthesia & Analgesia 136(1):p 86-93, January 2023. BACKGROUND: Previous studies have suggested that administration of epidural 3% 2-chloroprocaine (CP) before epidural morphine results in decreased analgesic efficacy of epidural morphine. We sought to determine whether these observations were a result of antagonism or a window period between the conclusion […]

BACKGROUND: The aim of this study was to explore whether ice slush (IS) causing local hypothermia can effectively inhibit the oculocardiac reflex (OCR) during strabismus surgery. METHODS: This prospective, randomized, double-blind study included 58 patients with concomitant strabismus scheduled for lateral rectus (LR) […]

BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) can present with severe respiratory distress requiring intensive care unit (ICU)–level care. Such care often requires placement of an arterial line for monitoring of pulmonary disease progression, hemodynamics, and laboratory tests. During the first wave […]
Read MoreAUTHORS: Jiang, Jia-Li MD et al Anesthesia & Analgesia 136(1):p 60-69, January 2023. BACKGROUND: The effect of anesthesia regimens on postoperative delirium after on-pump cardiac valve surgery is yet undetermined. This study aimed to evaluate the effect of volatile anesthesia compared with propofol-based total intravenous anesthesia (TIVA) on the occurrence of delirium after on-pump cardiac valve […]
