Therapeutic Hypothermia Protects Against Heat Stroke-Induced Arterial Hypotension via Promoting Left Ventricular Performance in Rats.
Authors: Ko WC, Lin CH, Lee JJ, Chang CP, Chao CM Abstract We aimed to ascertain whether therapeutic hypothermia (TH) acts as cardioprotective management for heat stroke (HS). Adult male rats under general anesthesia were exposed to whole-body heating (43°C for 70 min) to induce HS. Rats with HS displayed hyperthermia (core body temperature 42°C vs. 36°C); hypotension (30 mmHg vs. 90 mmHg mean arterial blood pressure); suppressed left ventricular (LV) performance (stroke volume 52 μl/min vs. 125 μl/min), ejection fraction (0.29% vs. 0.69%), relaxation factor (72 ms vs. 12 ms), and arterial elastance (0.31 mmHg...

Perioperative Care of Patients at High Risk for Stroke During or After Non-cardiac, Non-neurological Surgery: 2020 Guidelines From the Society for Neuroscience in Anesthesiology and Critical Care
Perioperative stroke is associated with considerable morbidity and mortality. Stroke recognition and diagnosis are challenging perioperatively, and surgical patients receive therapeutic interventions less frequently compared with stroke patients in the outpatient setting. These updated guidelines from the Society for Neuroscience in Anesthesiology and Critical Care provide evidence-based recommendations regarding perioperative care of patients at high risk for stroke. Recommended areas for future investigation are also proposed.

Does General Anesthesia Compared With Conscious Sedation Result in Better Outcomes in Acute Stroke Patients Undergoing Endovascular Therapy?
Conclusions: GA does not result in worse tissue outcomes or worse clinical outcomes when compared with CS in acute stroke patients with large vessel occlusion undergoing mechanical thrombectomy.

Anesthetic Management of Acute Ischemic Stroke in the Interventional Neuro-Radiology Suite: State of the Art
Purpose of review This review discusses the general anesthetic approach of endovascular stroke therapy and highlights recent advances and considerations for optimal intraoperative management of acute ischemic stroke. Recent findings Recent randomized controlled trials have shown no differences in clinical outcomes between monitored anesthesia care with sedation compared with general anesthesia for endovascular stroke therapy. The COVID-19 pandemic has complicated decision-making in the neurointerventional setting. Advances in imaging techniques have extended the window of treatment for endovascular therapy. S...

Worldwide anaesthesia use during endovascular treatment for medium vessel occlusion stroke
CONCLUSIONS: Anaesthesia approaches in MeVO EVT vary across world regions and patient and physician factors. Most physicians in this survey preferred to start with local anaesthesia or conscious sedation and convert to GA if necessary.PMID:34665059 | DOI:10.1177/15910199211041487

Long-term outcomes of percutaneous left atrial appendage closure for the prevention of stroke in patients with atrial fibrillation: Asia-Pacific experience
CONCLUSION: This long-term follow-up study shows that percutaneous closure of LAA is a safe and technically feasible procedure with satisfactory outcomes in Asia. The procedure success rate, efficacy and adverse event were similar to those reported in the Caucasian populations.PMID:34799213 | DOI:10.1016/j.jfma.2021.10.010

P-002 Perceived limits of endovascular treatment for secondary medium vessel occlusion stroke
ConclusionOur findings suggest that physician’s willingness to treat secondary MeVOs endovascularly is limited and varies per occlusion location and change in neurological status. More evidence on the safety and efficacy of EVT for secondary MeVO stroke is needed.Disclosures P. Cimflova: None. R. McDonough: None. M. Kappelhof: None. J. Ospel: None. N. Singh: None. N.

Risk Factors for General Anesthesia Conversion in Anterior Circulation Stroke Patients Undergoing Endovascular Treatment
Conclusion: In our study, tandem occlusion, longer endovascular procedures, SOFA, and number of pharmacological agents used predicted the risk of emergent conversion to GA in stroke patients undergoing endovascular treatment. Prospective studies investigating optimal CS strategies are deemed necessary.Cerebrovasc Dis

Team Prenotification Reduces Procedure Times for Patients With Acute Ischemic Stroke Due to Large Vessel Occlusion Who Are Transferred for Endovascular Therapy
Conclusions: Team prenotification results in faster patient assessment and initiation of EVT in patients with acute ischemic stroke. Its impact on functional outcome needs to be determined.

Genes, Vol. 14, Pages 1448: Isoflurane Anesthesia & rsquo;s Impact on Gene Expression Patterns of Rat Brains in an Ischemic Stroke Model
Conclusions: We were able to determine the effects of the duration of anesthesia using isoflurane on the transcriptomes in the brains of rats at 24 h after tMCAO. Thus, specific genome responses may be useful in developing potential approaches to reduce damaged areas after cerebral ischemia and neuroprotection.
