Anesthesiology, Q3 2026 edition
We read 4722 papers and selected 10.
Summary
Research during 2026-Q3 shifted anesthesiology toward individualized, mechanism-informed, and outcome-focused care. Large randomized trials challenged routine assumptions about anesthetic technique, airway devices, corticosteroid prophylaxis, and universal perioperative interventions. Translational studies advanced mechanistic understanding of postoperative cognitive dysfunction, developmental anesthetic neurotoxicity, cerebral venous-lymphatic physiology, and environmental thrombotic risk. Methodological progress included nationwide anesthesia registries, phenotype-guided therapeutics, multimodal molecular and imaging integration, and causal experimental approaches. The quarter also demonstrated that promising biomarkers and technologies require external validation and prospective impact studies before routine clinical adoption. Scientific influence was greatest where mechanistic discovery was linked to actionable clinical questions or reusable research infrastructure.
Selected Articles
1. Dapagliflozin and Acute Kidney Injury Following Cardiac Surgery: A Randomized Clinical Trial.
In a multicenter double-blind randomized trial of 784 adults undergoing elective cardiac surgery, four perioperative doses of dapagliflozin reduced seven-day acute kidney injury from 52% to 28% compared with placebo. The relative risk was 0.54, with similar atrial fibrillation and reoperation rates between groups.
Impact: This large, rigorous randomized trial addresses a common and serious complication with limited pharmacologic prevention options. The magnitude of benefit could reshape cardiac-surgery renal-protection research.
Clinical Implications: Dapagliflozin is promising but should be used only after replication and careful assessment of volume status, renal function, diabetes, and SGLT2 inhibitor-related safety risks.
Key Findings
- Acute kidney injury occurred in 28% with dapagliflozin versus 52% with placebo.
- The relative risk was 0.54 with a 95% confidence interval of 0.45 to 0.65.
- Atrial fibrillation and reoperation rates were similar between groups.
2. Cold exposure aggravates vein occlusion through non-shivering thermogenesis-induced thrombocytopoiesis.
This translational study connected cold exposure, adipose thermogenesis, fatty-acid metabolism, megakaryocyte maturation, platelet production, and venous thrombosis. Mechanistic mouse experiments and human observations suggested that cold seasons may increase thrombotic risk through an adipose-metabolic pathway.
Impact: The study introduced a novel environmental-metabolic explanation for seasonal thrombosis and linked multiple biological levels from adipose tissue to vascular occlusion.
Clinical Implications: Cold exposure may be a modifiable risk factor in susceptible patients, but the findings are translational and do not yet justify a specific clinical intervention.
Key Findings
- Cold exposure increased platelet counts and aggravated venous thrombosis in mice.
- Adipose thermogenesis and fatty-acid oxidation promoted acetyl-CoA-dependent platelet production.
- Pathway inhibition reduced cold-induced thrombocytopoiesis and venous occlusion.
3. Cerebral venous blood flow regulates intracerebral pressure and brain clearance via meningeal lymphatic vessels.
Human MRI observations and mouse experiments showed that cerebral venous outflow, meningeal lymphatics, intracranial pressure, edema, and brain-fluid clearance are functionally linked. Venous obstruction or lymphatic depletion impaired pressure recovery and clearance.
Impact: The study reframed intracranial pressure regulation as an integrated venous-lymphatic process rather than an isolated pressure phenomenon.
Clinical Implications: Venous outflow and meningeal lymphatic integrity may become relevant variables in neuroanesthesia and neurocritical care, although no new treatment standard is established.
Key Findings
- Venous sinus stenosis was associated with altered perivenous fluid patterns and brain edema.
- Jugular vein ligation caused transient intracranial hypertension and impaired clearance in mice.
- Meningeal lymphatic depletion worsened pressure elevation and prevented clearance recovery.
4. Inflammatory Phenotypes In Severe Pneumonia: Clinical Evidence To Mouse Models For Precision Therapeutics.
Latent class analysis identified hyperinflammatory and hypoinflammatory phenotypes in 548 critically ill patients with pulmonary sepsis. The hyperinflammatory phenotype had greater lung injury and mortality, and experimental corticosteroid or IL-6 receptor blockade benefited only the more inflamed phenotype.
Impact: The study linked clinically observed inflammatory subgroups to experimental biology and differential treatment response, providing a strong precision-critical-care framework.
Clinical Implications: Biomarker-guided immunomodulation is promising but requires prospective biomarker-stratified clinical trials before implementation.
Key Findings
- Two inflammatory phenotypes were identified among 548 patients with pulmonary sepsis.
- The hyperinflammatory phenotype was associated with greater lung injury and mortality.
- Dexamethasone and IL-6 receptor blockade benefited only the more inflamed experimental phenotype.
5. 14-3-3γ Protects Against Postoperative Cognitive Dysfunction by Regulating Tau Thr205 Phosphorylation and Synaptic Integrity.
Human proteomics, a prospective surgical cohort, cellular studies, and mouse experiments identified 14-3-3γ as a potential biomarker and mechanistic regulator of postoperative cognitive dysfunction. Genetic overexpression or pharmacological stabilization of the 14-3-3γ-Tau interaction improved cognition and synaptic integrity in mice.
Impact: The paper moved postoperative cognitive dysfunction research from association toward a biologically defined and potentially druggable pathway.
Clinical Implications: The biomarker and pathway are not ready for routine clinical use, but they support prospective risk-stratification studies and future therapeutic trials.
Key Findings
- 14-3-3γ was identified through CSF proteomics as a marker of cognitive vulnerability.
- Plasma 14-3-3γ was associated with postoperative cognitive dysfunction and delirium.
- Genetic or pharmacological stabilization improved Tau phosphorylation, cognition, and synaptic function in mice.
6. CX3CL1/CX3CR1-dependent microglial phagocytosis of oligodendrocyte precursor cells contributes to sevoflurane-induced myelination impairments in neonatal mice.
Repeated neonatal sevoflurane exposure caused hypomyelination and persistent neurobehavioral deficits in mice. The effects involved CX3CL1/CX3CR1 signaling and excessive microglial phagocytosis of oligodendrocyte precursor cells, while CX3CR1 deletion attenuated the abnormalities.
Impact: The study identified a specific neuroimmune pathway rather than merely reporting an exposure-outcome association.
Clinical Implications: The findings support caution and further research regarding repeated early-life anesthesia exposure, but do not establish harm in human infants or justify immediate practice changes.
Key Findings
- Repeated but not single neonatal sevoflurane exposure caused hypomyelination and persistent deficits in mice.
- CX3CL1/CX3CR1 signaling promoted microglial phagocytosis of oligodendrocyte precursor cells.
- CX3CR1 knockout attenuated microglial, myelination, and behavioral abnormalities.
7. From data to quality: the story of A-QUA, Switzerland's Anaesthesia QUAlity initiative and database.
A-QUA is a nationwide Swiss anesthesia quality program whose registry contained more than 2 million cases from 54 centers by the end of 2024. Standardized data enabled benchmarking, detection of recurrent data-quality problems, and assessment of regional and hospital variation in practice.
Impact: The study's principal contribution is reusable infrastructure for quality improvement, reproducible research, and large-scale perioperative benchmarking.
Clinical Implications: Similar registries can identify preventable documentation and process errors, benchmark practice, and generate hypotheses for prospective safety research.
Key Findings
- The registry contained 2,045,026 anesthesia cases from 54 Swiss centers.
- General anesthesia accounted for 74% of cases, regional anesthesia alone for 18%, and monitored anesthesia care for 8.5%.
- Plausibility checks identified recurrent preventable errors and substantial institutional variation.
8. Conventional vs Video-Assisted Laryngoscopy for Perioperative Endotracheal Intubations: A Randomized Clinical Trial.
In the multicenter COVALENT trial, first-pass success was 78.2% with direct laryngoscopy, 82.9% with Macintosh video laryngoscopy, and 87.6% with hyperangulated video laryngoscopy. Both video approaches were superior to direct laryngoscopy.
Impact: This large pragmatic randomized trial provided strong evidence for a potential shift in routine airway management.
Clinical Implications: Video laryngoscopy should be strongly considered for routine operating-room intubation, while direct-laryngoscopy skills should remain available.
Key Findings
- First-pass success was 78.2% with direct, 82.9% with Macintosh video, and 87.6% with hyperangulated video laryngoscopy.
- Both video laryngoscopy techniques were superior to direct laryngoscopy.
- Hyperangulated devices had fewer reported lip or dental injuries and blood on the blade.
9. Total Intravenous vs Volatile Inhalational Anesthesia for Major Noncardiac Surgery: A Randomized Clinical Trial.
In a pragmatic multicenter trial of 2,508 adults, total intravenous anesthesia did not improve days alive and at home at 30 days compared with volatile anesthesia. Mortality, delirium, recovery quality, and major complications were similar, although TIVA reduced thirst, hoarseness, and nausea and vomiting.
Impact: This large pragmatic trial directly challenged the assumption that TIVA universally improves postoperative recovery.
Clinical Implications: Anesthetic technique should be selected according to patient characteristics, postoperative nausea risk, procedure, expertise, and resources rather than presumed universal superiority of TIVA.
Key Findings
- Days alive and at home were 22.5 days with TIVA versus 22.4 days with volatile anesthesia.
- Mortality, delirium, quality of recovery, and major complications did not differ significantly.
- TIVA reduced thirst, hoarseness, and nausea and vomiting.
10. Preoperative High-Dose Corticosteroids in Digestive Cancer Surgery: A Randomized Clinical Trial.
In a double-blind multicenter trial of 1,210 patients undergoing elective curative digestive cancer surgery, preoperative methylprednisolone 20 mg/kg did not reduce major postoperative complications. Major complications occurred in 23% with methylprednisolone and 20% with placebo.
Impact: This large rigorous negative trial supports deimplementation of an ineffective perioperative intervention and prevents unsupported routine exposure to high-dose corticosteroids.
Clinical Implications: Routine methylprednisolone 20 mg/kg should not be used solely to prevent postoperative complications in this population.
Key Findings
- Major postoperative complications occurred in 23% versus 20% with placebo.
- There was no improvement in infection, wound healing, or hospital length of stay.
- The findings do not support routine preoperative high-dose corticosteroids.
