Filter by:The objective of this study is to verify, through a randomized, single-blind, multicentre, parallel and comparative study, the effectiveness of heparin sodium of porcine origin in patients undergoing heart surgery at that require the aid of cardiopulmonary bypass, through the control of hemostasis during and after surgery, based on the strengths of markers of coagulation TCA, TTPA, Anti-Xa, heparin bioavailable and loss of excessive blood (bleeding) at the end of the surgery.

Children (ages 0-12) that have heart surgery are often at a high risk of developing complications and have to be continuously monitored. Part of the routine care at UCLA includes using a monitor (continuous central venous oxygen saturation-ScvO2) to measure the amount of oxygen saturation in the tissues (indirectly) during surgery and in the intensive care unit. However, there is not much data on the use and effectiveness of this monitor in comparison to other monitors used for children. The purpose of this study is to further evaluate the effectiveness of the continuous central venous oxygen saturation (ScvO2) monitor in children and compare it with other monitors during a heart surgery. This is an observational study and the patients will not undergo any research specific procedures in the operating room (OR). The investigators will observe and record de-identified information, such as vital signs (heart rate, blood pressure, etc.), to evaluate the importance of the monitor. This study will also look at the demographics (age, gender, diagnosis, etc.) and treatments (type of surgery) received children undergoing heart surgery to improve quality of care. The investigators will also observe the same parameters in the ICU. The investigators hypothesized that low central venous saturations are associated with worse clinical outcomes.
The purpose of this study is to evaluate a new monitor that measures cardiac output (amount of blood pumped by the heart). The system that is being tested in this study, called Endotracheal Cardiac Output Monitor (ECOM), uses electricity (impedance cardiography) to measure cardiac output and is not harmful to the patient. This study will test the accuracy and efficacy of the ECOM system in anesthetized and sedated patients who, in the normal course of clinical care in the OR or ICU, are having cardiac output measured. The investigators propose that unlike the standard system for cardiac output measurement, the ConMed ECOM System should result in a simplified, inexpensive, continuous, less-invasive, and accurate method of measuring cardiac output. Such a technique could allow the rapid diagnosis of instability in the cardiovascular system for critically ill patients.
There is actually two techniques of subclavian vein ultrasonography-guided venous catheterization : the axial and longitudinal approach. Currently, nothing makes it possible to privilege one technique compared to the other. This study aims to determine the best ultrasonography-guided method.
In cardiac operations under cardiopulmonary bypass(CPB), monitoring of brain tissue oxygen saturation with infrared spectrophotoscopy leads to a reduction of the number of packed red cell(PRC) transfusions during the period of extracorporeal circulation.
The purpose of this study is to evaluate the effects of Remote Ischemic Preconditioning on cognitive function in patients undergoing cardiac surgery compared to control intervention.
This study will compare the clinical efficacy and safety of Voluven® and Human Albumin during elective open-heart surgery in pediatric patients.
Several studies have highlighted the cardioprotective effects of acute normovolemic hemodilution during cardiac surgery. The aim of our study is to show that an increase in endogenous erythropoietin (EPO) might explain the cardioprotective effects of acute normovolemic hemodilution against ischemia-reperfusion phenomena.
Patients undergoing high risk cardiac surgery (combined CABG and valvular procedures) will be randomized to receive a total intravenous anesthesia or an anesthesia plan with sevoflurane. The investigators want to document whether the cardioprotective properties of volatile agents could translate in an improved outcome after cardiac surgery in high risk patients.
