Filter by:The aim of this study is to evaluate the prokinetic effect of metoclopramide on gastric emptying in critically ill mechanically ventilated patients .
The purpose of this study is to evaluate the utility of a new device - an external wireless patch system (WPS) - to measure gastric motility and to compare this external wearable device with the most commonly used test to measure stomach emptying, the nuclear medicine gastric emptying scan (also called gastric scintigraphy).
Perioperative fasting is an essential patient safety measure to reduce the risk of pulmonary aspiration of gastric contents, a rare but potentially catastrophic complication of anesthetic and airway management. Anesthesiologists' concern about aspiration and the increasing awareness towards the negative impact of prolonged restriction of oral intake have shaped the current fasting guidelines. However, due to the perceived safety of prolonged fasting and practical considerations, adoption of the fasting guidelines is suboptimal. Gastric ultrasound is a quick, non-invasive method to evaluate gastric contents and aspiration risk. Gastric ultrasound can accurately discriminate between solid particles and fluid content, and mathematical models can reliably predict the volume of the gastric contents from the gastric antral area (GAA). This project aims to use gastric ultrasound to provide new data that can support management strategies in perioperative patients, that ensure both a low aspiration risk and an adequate nutritional support. The investigators will test the hypothesis that commercially available liquid meals can be safely used preoperatively. A pilot crossover, study on healthy volunteers will be conducted to determine the gastric emptying time of high-calorie drinks, as compared to clear fluid.
Gastric emptying measured with scintigraphy in patients after standard Roux-en-Y Gastric Bypass (S-RYGB), Banded-RYGB (B-RYGB) or Extended pouch-RYGB (E-RYGB).
The rate of gastric emptying is proposed to be one of the major determinants of postprandial glycemia. A slower gastric emptying will thus result in a less pronounced rise in blood glucose, which is especially desirable in diabetes care as it will highly influence the overall glycemic control. The present study aims to investigate the rate of gastric emptying and postprandial blood glucose levels in response to the intake of bread with different dietary fiber-content. Though bread is one of the major sources of dietary carbohydrates in Central- and Northern Europe, the mechanism and the metabolic effects of bread consumption, however, is investigated in a limited number of studies.
The purpose of the study is to explore the effects of GLP-1 receptor agonist (GLP-1 RA) semaglutide on modulation of taste sensitivity, tongue tissue transcriptome, modulation of neural response in central reward processing regions and gastric emptying rate. In addition, we aim to investigate the associations between semaglutide induced modulation of taste sensitivity, neural responses and gastric emptying with changes in body mass, eating- behavioural pattern, food perception and food intake.
Ultrasound guided comparison of gastric residual volume after clear fluid fasting for one versus two hours in pediatrics scheduled for elective surgery.
To investigate the effect of chewing lollipop on gastric volume and gastric emptying in healthy volunteers drinking water.
The aim of the study is to assess the difference in gastric emptying using ultrasound of pregnant patients following a cup of tea with milk or a similar volume of water.
The objective of this dose-finding and feasibility study is to establish the optimal 13C-octanoate concentration to be used with slowly infused enteral nutrition to perform a prolonged gastric emptying test using the breath test. More specifically, the aim is to discover the 13C-octanoate concentration that induces a steady state hourly 13C-recovery. This would allow to implement the prolonged breath test protocol in a future clinical investigation in critically ill patients.
