View clinical trials related to Hypotension.
Filter by:Many previous studies have investigated the ability of various methods such as passive leg raising test , and inferior vena cava collapsibility index in predicting post-spinal hypotension, but none of them have succeeded in obtaining a good predictive value. Our study aims to combine the passive leg raising test with the inferior vena cava distensibility index to aid in predicting post-spinal hypotension in elderly undergoing infra-umbilical surgeries.
The goal of this randomized controlled trial is to compare for non inferiority for fetal wellbeing Hypotension Prediction Index - Guided Therapy and Continuous Norepinephrine Infusion in in the Prevention of Spinal Anesthesia-Induced Hypotension for Cesarean Delivery. The main question it aims to answer are: • are fetal arterial base excess comparable with the two treatments? Participants will undergo continuous noninvasive hemodynamic monitoring with advanced Hypotension Prediction Index Researchers will compare with patients receiving continuous norepinephrine infusion and standard blood pressure monitoring with arm cuff.
To exclude hypovolemia before starting off pump coronary artery grafting surgeries by an efficient and good predictive test. We will assess the sensitivity and specificity of dynamic IVC-derived parameters (dispensability index) in comparison to carotid Doppler peak velocity as predictors of fluid response before skin incision in patients undergoing off Pump cardiac surgery.
Perioperative anesthesiologists can benefit from easily obtainable hemodynamic variables detecting or quantifying the lack of an adequate compensatory capacity of the cardiovascular system in order to optimize patient management and improve patient outcomes. Parameters of the Pressure Recording Analytical Method (PRAM; Vygon, Padua, Italy) of the MostCare system, specifically cardiac cycle efficiency has been proposed as such variables. Yet, their value in anesthesia and especially in hypertensive patients is not studied. The goal of the PRAM-in-HYPO study is to prospectively evaluate the relationship between cardiac reserve and efficiency and cardiovascular risk factors in patients wo will undergo major surgical procedures using the state-of-the-art hemodynamic monitors. Also the investigators aim to build a predictive model to identify patients with decreased cardiac reserve due to hypertension and other cardiovascular risk factors, who are susceptible to post-induction hypotension. The investigators seek to include high-risk patients or patients presenting for major surgery, who are monitored with an advanced hemodynamic monitor to adequately evaluate the differences in cardiac reserve and cardiac efficiency.
The goal of this clinical trial is to compare the effect of remimazolam and dexmedetomidine on the incidence of hypotension during spinal anesthesia in adult patients.
The purpose of this pilot trial is to examine the feasibility and ease of use of monitoring by ClearSight in laboring and delivering patients with the intent to compare time-to-treatment of hypotension between conventionally monitored patients (Group CM) and those receiving HPI (Group CM + HPI) monitoring by ClearSight, in a population of healthy laboring women who receive epidural analgesia.
The goal of this clinical trial is to investigate if the use of the hypotension prediction index during the perioperative period leads to a decrease in hypotension both during and after surgery (24 hrs) in adults undergoing major abdominal surgery. The main question this trial aims to answer is: • Does the use of the hypertension prediction index (HPI) decrease hypotension during surgery and in the post-operative period? During and after their surgery, participants in the intervention group will be treated according to the HPI-algorithm. Participants in the control group will be treated following the standard of care.
We will investigate the effect of hypotension prediction index guidance on intraoperative hypotension and metabolomics in patients undergoing major upper gastrointestinal surgery
Hypotension is a common side-effect of general anesthesia induction and is related to adverse outcomes including significantly increasing risk of one-year mortality. Even short durations of intraoperative hypotension have been associated with acute kidney injury (AKI) and myocardial injury.Half of all the patients were fluid-responsive, pointing to volume status as a significant risk factor. Ultrasound measurements of inferior vena cava (IVC) diameter with respiration, including the maximal diameter of the IVC (dIVCmax) at the end of expiration during spontaneous respiration and the collapsibility index (CI), have been recommended as rapid and noninvasive methods for estimating volume status. In attempt to prevent hypotension after spinal anesthesia induction, Ondansetron, a serotonin receptor antagonist, has been used effectively . Research Question Can preoperative IVC-US guided fluid optimization and intravenous ondansetron reduce the incidence of general anesthesia-induced hypotension in adult patients undergoing elective non-cardiac non-obstetric surgery?
The aim of the researchers was to evaluate the adequacy of graft function in the postoperative period of patients who underwent renal transplantation and encountered hypotension in the intraoperative period.
