Gastric Volume After Ingestion of Carbohydrate Drink vs Water in Obese Volunteers

Comparison of Gastric Residual Volume After Ingestion of Carbohydrate Drink and Water in Obese Volunteers: A Randomized Crossover Study

• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 30 (estimated)
• Sponsor: Prince of Songkla University · Academic / Other
• Sex: All
• Age: 18 Years – 65 Years
• Healthy volunteers: Accepted

Summary

This randomized crossover study compares gastric residual volume after ingestion of carbohydrate drinks and water in obese volunteers. The main question\[s\] it aims to answer are: * Is it safe for obese patients to shorten their fasting by allowing preoperative drinks? * How long is the gastric emptying time in obese patients? Participants also will be evaluated the level of thirst/hungry and blood sugar.

Conditions

• Obesity
• Gastric Emptying

Interventions

Type	Name	Description
PROCEDURE	Preopertive drink	* Group C: will receive a carbohydrate drink of 400 ml (50 g of glucose prepared by nutrition division, same appearance and containing bottles of water) * Group W: will receive water 400 ml (prepared by nutrition division, Songklanagarind hospital, same appearance and containing bottles of carbohydrate drink) In both groups, the received 400-mL drink was consumed within 5 minutes. * Before drinking, baseline data (gastric residual volume, POCT glucose, degree of hunger, and thirst) will be evaluated. * Gastric ultrasound will be performed by the same Radiologist on each participant at 0, 30, 60, 90, 120 minutes * after drinking to evaluate the gastric residual volume and time to empty gastric antrum. * POCT glucose and degree of hunger and thirst are also assessed again at 120 minutes after drinking. * After completing one type of drinking, participants will be appointed again after 1 week later for doing the same protocol with another drinking.
