Non-Invasive Cardiac Output Monitor in Children

Cardiac OutputLow1 more

This study will be the first of several studies that establish the value of measuring fluid responsiveness in children undergoing general anesthesia. The first study in this series will determine whether fluid responsiveness, as measured with the NICOM cardiac output monitor in normal children before and after passive leg raising, predicts changes in stroke volume, cardiac output, and blood pressure during the early stages of anesthesia. A second study will determine if early treatment of the fluid responsiveness will prevent the decline in blood pressure that accompanies general anesthesia. If the NICOM monitor permits accurate prediction in normal patients, future studies of pediatric patients undergoing major surgery would be indicated. The investigators would like to add 25 additional patients who will have the NICOM assessments performed in the pre operative area - Pre anesthesia. General anesthesia may alter the results of the NICOM assessments. The investigators will use these 25 subjects to serve as a comparison/control group.

Assessment of Volumetric Hemodynamic Parameters and Nutritional Status in Stable Renal Transplant...

Cardiac OutputLow1 more

Changes in volumetric hemodynamic parameters and fluid overload (Cardiac Index,Stroke Volume, Thoracic Fluid Content, Systemic Vascular Resistance) were measured using a impedance cardiography (ICG) (CardioScreen 1000 - Haemodynamic Measurement System, Medis. Ilmenau) in stable renal transplant recipients Nutritional status was measured by Tanita 418 Monitor.

Hemodynamic Monitoring in Liver Transplant With VEnaRt Cardiac Output Versus Swan-Ganz Catheter...

Cardiac OutputLow1 more

The Swan-Ganz catheter is the gold standard to measure cardiac output during liver transplantation surgery. This is an invasive hemodynamic monitoring system. The VenArt Cardiac Output (Mespere LifeSciences, Waterloo, Canada) is a new, innovative and non-invasive device that permits hemodynamic monitoring. With a software based on Fick's principle it is able to calculate cardiac output, cardiac index and continuous cardiac output. The hypothesis of this study is to investigate the precision and accuracy of this method versus the standard of care during liver transplantation.

Hemodynamic Survey Cardiac Surgical Scenarios

Low Cardiac Output

The purpose of this study is to find out the Lidco Rapid ( monitoring tool gives cardiac output) is as equivalent in determining the hemodynamic assessment in cardiac surgical scenarios as the most often used pulmonary artery catheter, which is much more invasive than the Lidco Rapid. This will be accomplished through online surveys which have different cardiac surgery scenarios and will be distributed to cardiac fellowship trained anesthesiologists. The online based survey will include a specific scenario and details on the scenario represented in image format and a brief description of the patient to aid with their analysis of the situation.

Is the Decrease in the Bispectral Index Correlated With a Decrease in Cardiac Output During the...

Thoracic Surgery

Monitoring the bispectral index (BIS) as a peri-operative hemodynamic tool appears to be justified by the agreement between various clinical situations in which BIS monitoring appears to be of value: the prognosis in traumatic head injury, the diagnosis of brain death , and the diagnosis of amniotic fluid embolism. The current controversy concerning the "triple low" state reinforces the need for an accurate study in this field. Furthermore, the recent review by Bidd argues in this sense.

How Much Cardiac Output is Enough?

Low Cardiac Output Syndrome

Low output syndrome is a common complication in patients undergoing cardiac surgery. Its incidence was reported to be 2 to 6% [1]. Morbidity and mortality of low output syndrome is high and the costs for treating the disease are immense. The primary objective of this prospective observational study is to define a threshold for a critically reduced cardiac output requiring immediate therapy.

Invasive pulmonary capillary wedge pressure measurements using a Swan-Ganz catheter (SGC) is considered the gold standard for cardiac output (CO) monitoring. In this prospective study, we will compare CO measurements between a PPG-based wearable monitor and a SGC in ambulatory CHF patients.

The purpose of this study was to compare CO measured by two easy to use non-invasive monitors, the esCCO (Nihon Kohden, Tokyo, Japan) to the Volume View (Edwards Lifesciences, Irvine, USA) and to assess their trending ability in patients undergoing cardiac surgery.
