There are some questions on the oxidative stress of the critical illness. First, the investigators want to search out the effects of the past history, smoking, alcohol drinking, use of ...


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 ...

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 ...

Population-based Brest Stroke Registry

The main objective of Brest Stroke Registry is to regroup all confirmed cases of stroke over a defined geographical zone in order to calculate an incidence. There are three prospective medium-term goals: In respect with public health epidemiology: To obtain incidence data and evaluate the regional and international divergences To ...
