Natural History of Stroke: Cause and Development

OBJECTIVE: This is a natural history/disease pathogenesis protocol for evaluation of patients with or at risk for acute stroke, transient ischemic attack (TIA), or other disturbances of cerebrovascular circulation. The purpose of this protocol is to generate natural history data to serve as the basis for future hypothesis-driven protocols as ...

An Observational Study of Natural History of Cardiovascular Diseases

Cardiovascular disease (CVD) affects the lives of millions of people and is one of the largest causes of death and disability in this country. Huge improvements have been made in the prevention and treatment of CVD over the last decade. However, comparisons with other countries show that England could still ...

Evaluation of Doppler Flow From the Femoral Artery as a Reflection of Cardiac Flow in a Vascular Fluid Test

It is notable that in the intensive care patient, the ultrasound measurement of cardiac flow is not always possible, especially in case of mechanical ventilation, often responsible for air interposed between the ultrasound probe and the heart, thus stopping the ultrasound. Use the blood pressure increase as a reflection of ...

Analysis of the Impact of the Fragility of the Over 70 Years of TIAprognosis

Hypotheses : Frailty is common among the elderly patient population who have a TIA. Compared to control groups of literature. Patients with high fragility score ABCD2 also have a high score. Patients with a high score of fragility also have a significant number of vascular risk factors (including atrial fibrillation) ...

Inferior Vena Cava Assessment in Term Pregnancy Using Ultrasound: a Feasibility Study of Subxiphoid and RUQ Views

Anesthesiology consultants and trainees with US experience will first perform scans from the RUQ view starting on the mid-axillary line at the T4 intercostal space, looking to obtain a view of the IVC as it enters the right atrium (RA). Following successful acquisition, the examiner will perform scan from the ...

Phase N/A

Evaluation of Resuscitation Markers in Trauma Patients

Severe trauma patients have an elevated risk of multiple organ failure and death. In order to increase survival possibilities the initial treatment must be focused into resuscitation from shock. Traditionally the most common resuscitation markers used are vital signs and urine output. Unfortunately, many patients might present normal vital signs, ...

Comparison of Allows Measurement of Cardiac Output Between Clearsight System and Transpulmonary Thermodilution

Since 2014, Edwards society has developed a completely non-invasive monitoring device for measurement of blood pressure and continuous cardiac output without inserting foreign intravascular bodies in the patient. Initially tested on healthy volunteers cardiac disease -free, the correlation with the other devices seems to be good. If this ClearSight system ...

Point of Care Ultrasonography In The Management of Undifferentiated Shock: A Pilot Randomized Controlled Trial

This project aims to determine the feasibility of conducting a randomized controlled trial investigating point of care ultrasound guided resuscitation compared with usual care in the management of undifferentiated shock at the Critical Care Trauma Centre (CCTC) in London Health Science Centre (LHSC).
