Essential Hypotension and Allostasis Registry

DEFINITIONS ARTERIAL BLOOD PRESSURE CLASSIFICATION Arterial Blood Pressure (ABP) is a complex physiological variable in regard to its measure, behavior between BP taken in the same visit at the office and between these and ABPM, chronobiology (different day time BP levels), evolution in time, meaning and classification. Not appropriate approach ...

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, ...

Cerebral Oxygenation and Neurological Outcomes FOllowing CriticAL Illness-2

This study is designed to test the hypothesis that poor cerebral perfusion during critical illness is a risk factor for acute and long-term neurological dysfunction among survivors. We use near-infrared spectroscopy to measure brain tissue oxygenation as a non-invasive surrogate marker for cerebral perfusion. Acute neurological dysfunction is defined as ...

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 ...

vapCO2 / Cav02 Ratio as a Prognostic Marker and Predictor of Complications After Cardiac Surgery

Cardiac surgery is widely used to solve valvular or coronary problems and often requires the use of cardiopulmonary bypass or extracorporeal circulation (EC). The EC itself produces a series of changes in the macro- and microcirculation hemodynamic and physiological consequences in the hours following surgery that can be difficult to ...

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

Diagnostic Investigation and Prediction of Shock

Patients frequently present to emergency departments (EDs) with critical illness and injury. Shock is a life-threatening emergency, which requires urgent and rapid assessment, diagnosis and treatment, and can be classified into distributive-septic (62%), distributive-non-septic (4%), hypovolaemic (16%), cardiogenic (16%) and obstructive (2%). Sepsis is the leading cause of in-hospital death, ...

Phase N/A

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 ...

Phase N/A

Stroke and Cerebrovascular Diseases Registry

Stroke is the fifth cause of all-cause mortality in US http://www.cdc.gov/stroke/facts.htm Early identification and treatment not only prevent mortality but also morbidity. Recent advancement in the imaging and diagnostic technique and novel therapeutic modalities has dramatically helped to downgrade stroke from the list of top mortality index in the last ...

Phase N/A

Evaluation of Three Dimensional Echocardiography in Critical Care Medicine

Prospective, observational study evaluating three dimensional echocardiography for measuring hemodynamic variables versus the current gold standard (pulmonary artery catheter). Critically ill patients with a severly compromised circulation due to a shock state with an advanced hemodynamic monitoring in place and the need for echocardiographic evaluation will be included. While performing ...
