Filter by:Title of the study: Target weight correction and vascular stiffness in hemodialysis patients Study design: Randomized clinical trial in the study centre at two locations Applied medical device: 1. Body Composition Monitor' (BCM, Fresenius) to measure fluid volume overload. 2. Arteriograph 24 (Tensiomed, Budapest, Hungry) to assess vascular stiffness before, during and after the intervention. Study hypothesis: A protocolized adjustment of target weight guided by bio-impedance spectroscopy will improve fluid status, systolic and diastolic blood pressure, and reduce the arterial wall stiffness without increasing the prevalence of intradialytic hypotension. Aim of the study: 1. To demonstrate improvement in fluid status by a target weight correction protocol which applies BCM measurements. 2. To demonstrate that better fluid volume control is associated with a) improvement in vascular health as assessed by pulse wave velocity and augmentation index and b) reduction in antihypertensive medications use. 3. To show that this approach does not lead to more episodes with intradialytic hypotension. The number of patients: 70 patients
Impact of intraoperative use of pneumatic peristaltic compression device on hemodynamics vis a vis on fluid requirement during general anaesthesia and surgery.
Sepsis is one of the most challenging conditions with an exceptionally high mortality rate. Diastolic Dysfunction is common in septic patients and has been found to be associated with mortality. However, the reasons for this remain unclear. Therefore, the goal of this study is to investigate diastolic dysfunction in septic patients on the intensive care unit. Special attention is paid to the presence of lung edema and general edema as a potential link between diastolic dysfunction and elevated mortality in septic patients. During the septic phase daily ultrasound examinations of heart and lung will be performed as to monitor diastolic function and lung edema.
This is a clinical randomised double blinded multicentre trial of two different fluid treatments during colorectal surgery in an enhanced recovery programme A restricted fluid regimen aiming at zero fluid balance and less than two kilograms bodyweight change was compared with another fluid regimen where intravenous fluids were given to reach near maximal stroke volume of the heart, guided by a Doppler in the oesophagus. The primary outcome was a composite outcome of postoperative complications and death. Included was 150 patients undergoing elective colorectal surgery. No difference was found between the two groups. Both fluid therapies resulted in low complication rates. The difference in fluid volume between the groups was only 600 ml on the day of operation. The results are published, see reference section.
Bedside lung ultrasound can detect pulmonary congestion by detecting the appearance of B-lines. Pulmonary edema may occur even without cardiomyopathy or heart failure, especially after excessive fluid administration. B-lines have been acknowledged as sonographic signs of pulmonary interstitial and alveolar edema in critical and emergency care. Limited scientific evidence on optimal intraoperative fluid management has resulted in large variations of administered fluid regimens in daily practice. The restricted perioperative intravenous fluid regimen reduces complications after elective surgeries, however other studies had shown that intraoperative liberal fluid administration improves postoperative organ functions and recovery and shortens hospital stay after elective surgeries.
The first objective of this study was to compare the traditional fluid management (TFM) with PVI guided goal-directed fluid management (GDFM) in terms of controlled intraoperative fluid volume, surgical end-point fluid balance, blood lactate and serum creatinine levels. ASA I-II 70 patients included in this prospective study.
The objective of the study is to evaluate influence of perioperative fluid therapy on Methemoglobin levels, and to changes in hemoglobin. Further, changes in Methemoglobin will be related to metabolic signs of oxidative stress (changes in blood lactate). Patients undergoing major abdominal surgery will be included into the study.
ratio of the diameter of inferior vena cava to the diameter of the thoracic aorta (IVC / Ao) depends on the daily balance of fluids.
Background: Anesthesia in free flap surgery is challenging. Monitoring of hemodynamic changes and their influence on the cardiovascular system in permanent feedback loops allow control, which is what anesthesiologists aim for to ensure an adequate blood flow and tissue oxygenation. The circulatory support and inferable volume administration are managed via heart rate (HR) and mean arterial pressure (MAP), but both parameters are influenced by variable components and are thus unfavorable for volume management. The aim of this study was to evaluate whether volume requirement may be assumable to additional monitoring parameters. Methods: 31 patients were enrolled prospectively. HR, MAP, central venous pressure and O2 saturation were comprehended based on the protocols. We expanded the data set by a permanent blinded intraoperative monitoring with registration of the Cardiac Index (CI) and Stroke Volume Variation (SVV) and semi-invasive pulse-contour analysis utilizing the Pro-AQT-Device.
This is a pilot randomized clinical trial in which patients treated with 3X per weekly conventional hemodialysis will be treated to a dialysate sodium 135 mEq/L vs. 138 mEq/L and followed for safety and tolerability, effects on BP and volume.
