Active clinical trials for "Hypovolemia"

Monitoring could secure management for patient but stay invasive. The purpose of this study was to compare,after cardiac surgery, the cardiac output measurement between transpulmonary thermodilution(reference method) and digital photoplethysmography (non invasive) for absolute value and dynamics changes before and after fluid expansion for patients with indication of fluid challenge.

Intravenous infusion of fluids in patients after surgery is a very important part of treatment. However, administering too much or too little fluid can lengthen the stay in the intensive care unit or even harm the patient. Therefore, fluid therapy should be tailored to the individual needs of each patient. Several methods are available to assess which patients will likely benefit from fluid administration. However, each of these methods is useful only under certain conditions. The study aims to explore some less-known, yet promising tests which could make adequate fluid administration more precise and easier to achieve.

The objectives of this study are to assess the risk of ketoacidosis, severe urinary tract infections, volume depletion, and dehydration associated in patients with T2DM initiating Empagliflozin compared to patient initiating a dipeptidyl peptidase-4 (DPP-4) inhibitors over a 12-month period of follow-up, including the month of Ramadan

Retrospective study that analyzes the changes in serum creatinine as a tool to correctly classify the volemic status volemic status (euvolemia vs hypovolemia) of the patients with hyponatremia.

The investigators hypothesize that analysis of blood pressure will allow doctors to predict whether or not blood flow from the heart (cardiac output) increases after intravenous fluids are given.

The objective of this study is to determine the accuracy of estimating patient blood volume using field-expedient point-of-care measurement of hematocrit before and after hemodilution with a standardized volume of intravenous solution, in comparison to determining patient blood volume by radiodilution. A total of 33 healthy adult male subjects aged 18-35 years will undergo determination of blood volume in a fixed order: first by radiodilution, then by hemodilution. Blood volume as measured by radiodilution will be correlated with blood volume as estimated with hemodilution to assess the potential validity of hemodilution as means of estimating blood volume.

The purpose of this study is to determine if extra systoles can be used to predict fluid responsiveness perioperatively in patients undergoing on pump coronary artery bypass graft (CABG) surgery. As an additional study we will investigate the ability of a mini fluid challenge to predict response of a larger volume of fluid.

The purpose of this study is to understand and document measurements in heart stroke volume (the volume or amount of blood pumped per heart beat) and cardiac output (the volume or amount of blood pumped by your heart per minute) during a passive leg raise maneuver (elevation of the legs), and to determine if these measurements can predict changes in the same as a result of fluid or blood product administration.

The primary objective of this study is to demonstrate that preoperative fasting does not increase the rate of lowered blood volume (defined by a variation of 15% ΔITV during a leg lift) in patients undergoing surgery.

It is the purpose of the researchers to identify the variation in intravascular deficits which can have relevance in high risk patients for minor and medium sized surgery. The investigators will also estimate fluid deficit in healthy, non-fasting subjects for comparison.
