NCT ID: NCT06440252 Not yet recruiting - Circulatory; Change Clinical Trials

Effectiveness of a Grape Seed Extract on Circulatory Measures in Healthy Adults

Start date: June 30, 2024
Phase: Phase 3
Study type: Interventional

This is a randomized, double-blind, placebo-controlled, 2 arm crossover study conducted over 11 weeks, with participants randomised to a product for 4 weeks, followed by a 3-week washout period before completing the second product for 4 weeks, to study the effectiveness of a grape seed extract on circulatory measures in healthy adults.

NCT ID: NCT05302219 Recruiting - Apnea Clinical Trials

Plethysmography Curve Variability Depending on the Breath Cycle

Start date: March 10, 2022
Phase: N/A
Study type: Interventional

The aim of the study is to analyze the variability of plethysmography curve depending on the breath cycle (respiratory rate and tidal volume).

NCT ID: NCT04630704 Not yet recruiting - Circulatory; Change Clinical Trials

Evaluating A Non-Invasive Tissue Perfusion Monitor

Start date: December 7, 2020
Phase:
Study type: Observational

The Pedra perfusion system will be used to assess changes in perfusion in response to physiological stimuli. It will be compared to other standard diagnostics.

NCT ID: NCT03724162 Completed - Microcirculation Clinical Trials

Evaluation of the Circulatory Status of Stomach Tube and Gastrooesophageal Anastomosis

Start date: July 16, 2018
Phase:
Study type: Observational [Patient Registry]

The incidence of anastomotic leaks after gastroesophageal anastomosis after thoracolaparoscopic cancer esophagus surgery is high at the Oslo University Hospital. The patients selected for operation shall be investigated for microcirculatory changes at the thoracic anastomosis site and followed up for any post operative anastomotic leaks.

NCT ID: NCT03563105 Active, not recruiting - Circulatory; Change Clinical Trials

Assessment of Circulatory Compromise With Ox-Imager Using a Vascular Occlusion Test Protocol

Start date: May 30, 2018
Phase: N/A
Study type: Interventional

The objective of this study is to evaluate the performance of Modulated Imaging Inc.'s (MI) next generation Spatial Frequency Domain Imaging (SFDI) system to measure potential circulatory compromise.

NCT ID: NCT03371537 Completed - Liver Dysfunction Clinical Trials

Study of Hemodynamic Conditions Measured During Hepatectomy

DEBIFOIE
Start date: October 8, 2017
Phase:
Study type: Observational

Hepatocellular insufficiency is a dreaded complication after hepatectomy, since, if it is persistent, it leads to the death of the patient in the absence of liver transplantation. The preoperative evaluation aims in particular to estimate the risk of postoperative hepatocellular insufficiency so as to minimize or contraindicate high-risk patients. It has been shown that the flow of the portal vein is correlated with liver function, especially in the living donor and after portal embolization. More recently, the study of flow rates in the portal vein and the hepatic artery after transplantation has shown a correlation with the recovery of graft function. The hypothesis is that portal and arterial flow after hepatectomy can predict postoperative hepatocellular function.

NCT ID: NCT03023488 Completed - Circulatory; Change Clinical Trials

Effects of Flexible Ureteroscopy on Renal Blood Flow

Start date: February 2016
Phase: N/A
Study type: Interventional

Aim of this study is to investigate the effects of increased intrarenal pressure during flexible ureteroscopy on renal blood flow. Patients undergoing flexible ureteroscopy (F-URS) and laser lithotripsy for kidney stones according to European Association of Urology (EAU) guidelines on Urolithiasis will be included in the study after having signed an informed consent form. The pre- and post-operative evaluation and management will be performed according to EAU Guidelines on Urolithiasis. Additionally, as a non-invasive test, bilateral renal power Doppler US will be performed to patients pre- and post-operatively. The pre-operative Doppler US will be performed 2 days prior to surgery and the post-operative Doppler US will be performed in the first 24 hours following surgery. The changes on blood flow in renal artery and arcuate artery will be recorded.

NCT ID: NCT02727829 Completed - Circulatory; Change Clinical Trials

The Assessment of Microcirculation in Brachial Plexus Block Using Perfusion Index and Capillary Filling Time

Start date: May 1, 2016
Phase: N/A
Study type: Observational

The aim of the present study is to assess the effects of brachial plexus block on microcirculation using pefusion index and capillary filling time.

NCT ID: NCT01417754 Completed - Circulatory; Change Clinical Trials

Changes in Breast 3D Ultrasound Measurements Using Toremifene

Start date: September 2010
Phase: Phase 3
Study type: Interventional

To investigate if there are detectable changes in volume and circulation in breasts of healthy volunteers using toremifene 20 mg in luteal phase of the menstruation cycle versus nonmedicated cycle.
