Repeated neonatal isoflurane exposure is associated with higher susceptibility to chronic variable stress-induced behavioural and neuro-inflammatory alterations.

Neuroscience 2021 May 2. Epub 2021 May 2.

Department of Anaesthesiology and Operating Theatre Services, Xiangya Hospital of Central South University, Changsha city, Hunan Province, PR China; Teaching and Research Section of Anesthesia and Critical Care Medicine, Xiangya Hospital of Central South University, Changsha city, Hunan Province, PR China. Electronic address:

Numerous studies have reported that prolonged or multiple exposures to anaesthetics in early life lead to detrimental effects on brain function, most having focused on neurocognitive function, and relatively few on long term neuropsychiatric performance. The present study investigated the impact of repeated neonatal isoflurane exposure on chronic variable stress (CVS)-induced psychiatric and behavioural outcomes together with CVS-related neuronal activity and neuro-inflammatory reactivity in relevant brain circuits. In the present study, C57BL/6J mice received either three exposures to isoflurane at postnatal days 7, 8, and 9 or a control exposure. Read More

Anterior insula regulates brain network transitions that gate conscious access.

Cell Rep 2021 May;35(5):109081

Department of Anesthesiology, University of Michigan Medical School, Ann Arbor, MI 48109, USA; Center for Consciousness Science, University of Michigan Medical School, Ann Arbor, MI 48109, USA; Neuroscience Graduate Program, University of Michigan, Ann Arbor, MI 48109, USA. Electronic address:

Conscious access to sensory information is likely gated at an intermediate site between primary sensory and transmodal association cortices, but the structure responsible remains unknown. We perform functional neuroimaging to determine the neural correlates of conscious access using a volitional mental imagery task, a report paradigm not confounded by motor behavior. Titrating propofol to loss of behavioral responsiveness in healthy volunteers creates dysfunction of the anterior insular cortex (AIC) in association with an impairment of dynamic transitions of default-mode and dorsal attention networks.

From Royal Perth Hospital (T.B.C., P.C., K.M.H.), the University of Western Australia (T.B.C., E.O., K.M.H.), Murdoch University (K.M.H.), and Fiona Stanley Hospital (E.O.), Perth, and the Alfred Hospital (P.S.M., A.C.C., L.A.B.), Monash University (T.B.C., P.S.M., A.B.F., A.C.C., L.A.B., K.L., C.M.), the University of Melbourne (K.L., D.S.), and Royal Melbourne Hospital (K.L.), Melbourne, VIC - all in Australia; the Chinese University of Hong Kong, Hong Kong (M.T.V.C.); and Auckland City Hospital and the University of Auckland - both in Auckland, New Zealand (T.G.S.).

Background: The glucocorticoid dexamethasone prevents nausea and vomiting after surgery, but there is concern that it may increase the risk of surgical-site infection.

Methods: In this pragmatic, international, noninferiority trial, we randomly assigned 8880 adult patients who were undergoing nonurgent, noncardiac surgery of at least 2 hours' duration, with a skin incision length longer than 5 cm and a postoperative overnight hospital stay, to receive 8 mg of intravenous dexamethasone or matching placebo while under anesthesia. Randomization was stratified according to diabetes status and trial center. Read More

Long-term changes in self-reported sleep quality and risk of chronic musculoskeletal pain: The HUNT Study.

J Sleep Res 2021 May 5:e13354. Epub 2021 May 5.

Department of Public Health and Nursing, Norwegian University of Science and Technology (NTNU), Trondheim, Norway.

We examined the association between long-term (~10 years) changes in self-reported sleep quality and risk of any chronic musculoskeletal pain and chronic widespread pain. The study comprised data on 6,033 people who participated in three consecutive surveys in the Norwegian HUNT Study (1995-1997, 2006-2008 and 2017-2019) and who were without chronic musculoskeletal pain at the first two surveys. We used a modified Poisson regression model to calculate adjusted risk ratios for chronic pain at follow-up (2017-2019) associated with categories of poor and good sleep quality reported in 1995-1997 and 2006-2008.

Isoflurane Suppresses Hippocampal High-frequency Ripples by Differentially Modulating Pyramidal Neurons and Interneurons in Mice.

Anesthesiology 2021 May 5. Epub 2021 May 5.

Background: Isoflurane can induce anterograde amnesia. Hippocampal ripples are high-frequency oscillatory events occurring in the local field potentials of cornu ammonis 1 involved in memory processes. The authors hypothesized that isoflurane suppresses hippocampal ripples at a subanesthetic concentration by modulating the excitability of cornu ammonis 1 neurons. Read More

An Entrustable Professional Activities Model for Assessment of Undergraduate Competence in Anesthesia and Surgery: Performance of the Assessment Scheme and the Impact of Assessment Timing and Variation in Structure of Teaching Activities on Student Outcomes.

J Vet Med Educ 2021 May 4:e20200109. Epub 2021 May 4.

An entrustable professional activity (EPA) model was used to assess the anesthesia and surgery competence of year 4 students during elective neutering procedures over 3 academic years (cohort A, cohort B, and cohort C). Two competence thresholds were defined by an expert panel, the minimum acceptable standard (MAS) and the standard expected at the start of final-year rotations (SFR). The assessment scheme performed as expected, and the median level of supervision achieved by students either matched or exceeded the SFR for all EPAs except one, which matched the MAS. Read More

Methods for dose quantification in continuous renal replacement therapy: towards a more precise approach.

Artif Organs 2021 May 5. Epub 2021 May 5.

Department of Health Sciences, Section of Anaesthesiology, Intensive Care and Pain Medicine, University of Florence, Italy.

Periodic dose assessment is quintessential for dynamic dose adjustment and quality control of continuous renal replacement therapy (CRRT) in critically ill patients with acute kidney injury (AKI). The flows-based methods to estimate dose are easy and reproducible methods to quantify (estimate)CRRT dose at the bedside. In particular, quantification of effluent flow and, mainly, the current dose (adjusted for dialysate, replacement, blood flows and net ultrafiltration) is routinely used in clinical practice.
