Study of Hemoglobin A1c Levels and Their Effect on Gastric Emptying Using Bedside Gastric Ultrasound in Adults Undergoing Elective Surgery

What this Trial Is About

This research aims to study the relationship between hemoglobin A1c HbA1c levels, a marker of long-term blood sugar control, and gastric emptying in adults undergoing elective surgery. Delayed gastric emptying can increase the risk of lung aspiration during general anesthesia, especially in patients with diabetes or poor glycemic control. However, the connection between HbA1c and how quickly the stomach empties in surgical patients is not fully known. Adult patients aged 18 to 70 years who are scheduled for elective surgery under general anesthesia will take part. Before anesthesia, each participant will have a bedside gastric ultrasound performed to measure the size of the stomachs antral cross-section and estimate gastric volume after standard fasting. Researchers will compare these ultrasound findings to patients HbA1c levels obtained from preoperative lab tests. Participants will provide demographic and clinical information including body measurements and fasting duration. The study will focus on how HbA1c levels relate to gastric emptying and will explore other factors that might delay stomach emptying. The main measurement is gastric emptying assessed by ultrasound immediately before anesthesia. This study may help improve risk assessment for aspiration and support personalized anesthesia care in patients with blood sugar control issues.
