Improved cardiac filling facilitates the postprandial elevation of stroke volume in Python regius RESEARCH ARTICLE
Sanne Enok, Gabriella Leite, Cleo Leite, Hans Gesser, Michael S. Hedrick, and Tobias WangTo accommodate the pronounced metabolic response to digestion, pythons increase both heart rate and elevate stroke volume, where the latter has been ascribed to a massive and fast cardiac hypertrophy. However, numerous recent studies show that heart mass rarely increases even upon ingestion of large meals, and we therefore explored the possibility that a rise in mean circulatory filling pressure (MCFP) serves to elevate venous pressure and cardiac filling during digestion. To this end, we measured blood flows and pressures in anaesthet...

Effects of Workflow Optimization in Endovascularly Treated Stroke Patients – A Pre-Post Effectiveness Study
This study analyzes the effect of optimized workflow on periprocedural timings and its potential influence on clinical outcome. Data were extracted from a prospectively maintained university hospital stroke database. The standard ope rating procedure was established in February 2014. Of the 368 acute stroke patients undergoing endovascular treatment between 2008 and 2015, 278 patients were treated prior to and 90 after process optimization. Outcome measures were periprocedural time intervals and residual functional impairment. A fter implementation of the SOP, time from symptom onset to reperfusion was significantly reduce...

Even Small Decreases in Blood Pressure during Conscious Sedation Affect Clinical Outcome after Stroke Thrombectomy: An Analysis of Hemodynamic Thresholds INTERVENTIONAL
CONCLUSIONS: A ≥10% mean arterial pressure drop from baseline is a strong risk factor for poor outcome in a homogeneous population of patients with stroke undergoing thrombectomy under sedation. This threshold could guide hemodynamic management of patients during sedation and general anesthesia.

Anesthetic Neuroprotection in Experimental Stroke in Rodents A Systematic Review and Meta-analysis
Background Patients undergoing endovascular therapy for acute ischemic stroke may require general anesthesia to undergo the procedure. At present, there is little clinical evidence to guide the choice of anesthetic in this acute setting. The clinical implications of experimental studies demonstrating anesthetic neuroprotection are poorly understood. Here, the authors evaluated the impact of anesthetic treatment on neurologic outcome in experimental stroke.Methods Controlled studies of anesthetics in stroke using the filament occlusion model were identified in electronic databases up to December 15, 2015. The primary outcom...

Management of acute ischemic stroke due to tandem occlusion: should endovascular recanalization of the extracranial or intracranial occlusive lesion be done first?
CONCLUSIONS Tandem occlusions present treatment challenges, but high recanalization rates were possible in the present series using acute carotid artery stenting and mechanical thrombectomy concurrently. Proximal-to-distal and aspiration approaches were most commonly used because they were safe, efficacious, and feasible. Further study in the setting of a randomized controlled trial is needed to determine the best sequence for the treatment approach and the best technology for tandem occlusion.

Carotid artery disease and periprocedural stroke risk after transcatheter aortic valve implantation.
CONCLUSION: Bilateral carotid disease is a significant risk factor for perioperative strokes following TAVI. Preoperative screening with carotid Doppler to identify high-risk patients appears to be warranted. In addition, patients of female gender were found to have an increased risk for carotid disease.

Assessment and treatment of spastic equinovarus foot after stroke: Guidance from the Mont-Godinne interdisciplinary group.
CONCLUSION: Based on 20 years of interdisciplinary expertise of management of the spastic foot, guidance was established to clarify a complex problem in order to help clinicians treat spastic equinovarus foot. This work should be the first step in a more global international consensus. PMID: 28451697 [PubMed - as supplied by publisher]

CONCLUSIONS: In this single-center study, the anesthetic management during stent retriever thrombectomy with general anesthesia or conscious sedation had no impact on the outcome of patients with large-vessel occlusion in the anterior circulation.

Risks of Cardiovascular Adverse Events and Death in Patients With Previous Stroke Undergoing Emergency Noncardiac, Nonintracranial Surgery: The Importance of Operative Timing
(Abstracted from Anesthesiology 127(1):9–19, 2017) The purpose of this study was to assess the risk of adverse events after emergency noncardiac, noncranial surgery in association with time elapsed after ischemic stroke by retrospectively analyzing the data from a nationwide study population from Denmark that covered patients older than 20 years undergoing the aforementioned emergency surgeries between 2005 and 2011. The primary outcomes measured were the 30-day all-cause mortality and a combined end point of 30-day major adverse cardiovascular events (MACEs), such as nonfatal myocardial infarction and ischemic stroke, ...

Usefulness of Consciousness Sedation with Dexmedetomidine and Pentazocine during Endovascular Treatment for Acute Stroke.
Authors: Nii K, Hanada H, Hiraoka F, Eto A, Mitsutake T, Tsutsumi M Abstract We investigated the safety and efficacy of consciousness sedation with dexmedetomidine (DEX) during the endovascular treatment of patients with acute cerebral infarction. Between April 2014 and November 2016, 38 stroke patients underwent endovascular thrombectomy (EVT) under local anesthesia and DEX consciousness sedation. The continuous intravenous administration of low-dose DEX (0.3-0.4 μg/kg/h) was started before entering the operating room. Patients not completely immobilized received an iv bolus of pentazocine (PTZ) and/or DEX (0.5-0...
