General anesthesia or conscious sedation for thrombectomy in stroke patients: an updated systematic review and meta-analysis
CONCLUSIONS: In this updated systematic review and meta-analysis, the choice of anesthetic strategy for endovascular treatment of stroke patients did not significantly impact functional outcome as measured with the mRS at three months. Patients managed with general anesthesia may have more frequent successful reperfusion.TRIAL REGISTRATION: PROSPERO (CRD42022319368); registered 19 April 2022.PMID:37268801 | DOI:10.1007/s12630-023-02481-8

Predictors and outcome of early neurological deterioration after endovascular thrombectomy: a secondary analysis of the DIRECT-MT trial
Conclusions Postoperative END is associated with adverse functional outcome. Several non-modifiable and modifiable factors can predict END and support future treatment decision-making to improve the potential utility of endovascular thrombectomy. Trial registration number DIRECT-MT ClinicalTrials.gov NCT03469206.

High-frequency cortical activity associated with postischemic epileptiform discharges in an in vivo rat focal stroke model.
Conclusions These recordings provide the first intracortical evidence of a high-frequency component that could be an important element for diagnosis and intervention in postischemic epileptogenic activity. The early onset also suggests that HFOs could serve as a reliable method of detecting small epileptiform events and could be used as a consideration in deciding whether antiepileptic medications are appropriate as part of a patient's poststroke care.

Estimation of left ventricular stroke volume by impedance cardiography: its relation to the aortic reservoir
New Findings •What is the central question of this study?Thoracic impedance has been used to calculate left ventricular stroke volume for decades, while its theoretical basis remains controversial and the parameters generated have not been related satisfactorily to the haemodynamic events. •What is the main finding and what is its importance?We provide mechanistic explanations for the following: (i) why the upstroke of the change in thoracic impedance (ΔZ) waveform is constantly delayed with respect to that of the central aortic pressure; (ii) why the contour of the ΔZ waveform is ‘blunted’ compared with that of...

Comparison of stroke volume and fluid responsiveness measurements in commonly used technologies for goal-directed therapy
Abstract: Study Objective: To compare stroke volume (SV) and preload responsiveness measurements from different technologies with the esophageal Doppler monitor (EDM).Design: Prospective measurement study.Setting: Operating room.Patients: 20 ASA physical status 3 patients undergoing vascular, major urological, and bariatric surgery.Interventions: Subjects received fluids using a standard Doppler protocol of 250 mL of colloid administered until SV no longer increased by>10%, and again when the measured SV decreased by 10%.Measurements: Simultaneous readings of SV, stroke volume variation (SVV) and pulse pressure variation (...

Pressure recording analytical method and bioreactance for stroke volume index monitoring during pediatric cardiac surgery
ConclusionsPressure recording analytical method and bioreactance provided similar SVI estimation at stable hemodynamic conditions, while bioreactance SVI values appeared significantly lower than PRAM at the end of CPB and after fluid replacement.

Respiratory stroke volume variation assessed by oesophageal Doppler monitoring predicts fluid responsiveness during laparoscopy
Conclusions respSV and respPV predicted fluid responsiveness during laparoscopy under strict physiological conditions. FTc was not predictive of fluid responsiveness during laparoscopy.

Cost analysis of the stroke volume variation guided perioperative hemodynamic optimization - an economic evaluation of the SVVOPT trial results
Conclusions: Intraoperative fluid optimization with the use of stroke volume variation and Vigileo/FloTrac system showed not only a substantial improvement of morbidity, but was associated with an economic benefit. The cost-savings observed in the overall costs of postoperative care trend to offset the investment needed to run the GDT strategy and intraoperative monitoring.Trial registration: ISRCTN95085011

The Use of Pulse Pressure Variation and Stroke Volume Variation in Spontaneously Breathing Patients to Assess Dynamic Arterial Elastance and to Predict Arterial Pressure Response to Fluid Administration.
CONCLUSIONS:: Noninvasive Eadyn, defined as the PPV to SVV ratio, predicted the arterial blood pressure increase to fluid administration in spontaneously breathing, preload-dependent patients. PMID: 25230102 [PubMed - as supplied by publisher]

Intra-Arterial Therapy for Acute Ischemic Stroke Under General Anesthesia versus Monitored Anesthesia Care
Conclusion: Our study has confirmed previous findings of GA being associated with poorer outcomes and higher mortality in patients undergoing IAT for AIS. Detailed analysis of intra-procedural hemodynamics did not reveal any significant difference between the two groups. Parenchymal hematoma was the major driver of the difference in outcomes.Cerebrovasc Dis 2014;38:262-267
