Filter by:This study aims to compare the volume management methods performed by using conventional method and PVI monitoring in intraoperative fluid treatment during bilateral salpingo-oophorectomy and total hysterectomy operation.
This purpose of this study is to determine the effectiveness of a mobile phone application in helping to control body swelling in patients with kidney problems. The application will help in the day to day adjustments in diuretic medication dosing. Participants in this study will have an application loaded on to their mobile phone by the study team and be taught how to use it over a 2 hour visit. Participants will need to check their blood pressure and weight daily and enter this information into the mobile phone application every day. Participants will need to follow daily instructions in their medication dosing provided by the application. There will be periodic blood testing. This will happen at 2 weeks, 90 days, and up to 4 other times if necessary. At the end of the study there is a 2 hour study visit during which participants will answer a survey. The total length of the study is 90 days.
Although many alternative methods are present, maintaining ideal volume status in peritoneal dialysis (PD) patients still rely on clinical evaluation due to lack of an evidence based method. Lung ultrasound (LUS) is a new method for evaluation of hidden congestion in this group. LUS findings and its relationship with other volumetric methods are investigated in this study. LUS was performed to all peritoneal dialysis patients and compared with symptoms of hypervolemia, physical examination, vascular endothelial growth factor-C (VEGF-C) and N-terminal pro-brain natriuretic peptide levels, chest radiography, echocardiography, bioelectrical impedance analysis.
The overall goal of this multicenter project is to characterize the expected normal range of Peripheral IntraVenous Volume Analysis (PIVA) values during a euvolemic state, and how those ranges may be altered by comorbidities; the relationship between PIVA and intravenous volume administration during resuscitation of infected patients with presumed hypovolemia; and, the relationship between PIVA and volume decreases during diuresis in acute heart failure patients with hypervolemia.
The decision to give fluids perioperatively could be based on methods used to identify preload responsiveness, either invasive or noninvasive estimates of stroke volume variation during mechanical ventilation. This study compares fluid management using continuous noninvasive cardiac output measurement with standard perioperative fluid management.
Robot assisted urological procedures are often long surgical cases that can potentially result in complicated postoperative hospital course. The amount of intravenous (IV) fluids administered to patients during these operations fluctuates based on the length of the case, surgical blood loss, hemodynamic monitors, and the discretion of the anesthesiologist. The goal of intraoperative fluid therapy is to maintain optimal tissue perfusion without causing fluid overload. We plan to use a goal directed fluid therapy protocol to optimize fluid status and analyze post-operative outcomes.
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 use the photo-plethysmographic [PPG] waveform signal to guide the dialysis and ultrafiltration [UF] of chronic maintenance hemodialysis patients, and to further the investigators understanding of homeostasis in hemodialysis. The investigators hypothesize that the signals generated from the PPG device along with traditional monitoring and nursing judgment, will allow experienced, oriented staff to anticipate hemodynamic instability, intervene to prevent or mitigate the intradialytic hypotention [IDH], forestalling the onset of non-facilitating compensatory reflexes that preclude the patient from achieving an appropriate post-dialysis weight consistent with euvolemia. Furthermore, it is hypothesized that the nephrologist and staff will be able to wean patients from anti-hypertensive medications and craft patient specific dialysis orders and UF profiles that achieve consistent, comfortable treatment to appropriate end points. The study aims include: Aim 1: To confirm the temporal sequence of PPG signals and changes in BP in routine hemodialysis. Aim 2: To refine further the predictive algorithms of PPG, augmented with continuous cardiac event monitoring (pre-intra-post hemodialysis) Aim 3: To develop targeted interventions to reverse the cardiovascular stress indicated by the PPG and to maintain perfusion. Aim 4: To develop care paths approved by the medical staff and primary care nephrologist allowing RNs to respond to signals from the PPG.
This study proposes to examine the correlation of central venous pressure to measures of the diameter of the inferior vena cava as determined by bedside ultrasonography.
The study will evaluate the effectiveness and safety of multiple dosing regimens of IV conivaptan in subjects with euvolemic or hypervolemic hyponatremia
