HbA1c Levels and Gastric Emptying Assessed by Gastric Ultrasound
Condition(s) studied
Study summary
Delayed gastric emptying increases the risk of pulmonary aspiration during general anesthesia. Diabetes mellitus and poor long-term glycemic control have been associated with impaired gastric motility. Hemoglobin A1c (HbA1c) is a marker of long-term glycemic control; however, its relationship with gastric emptying in surgical patients is not fully understood.
This prospective observational study aims to evaluate the association between HbA1c levels and gastric emptying using preoperative bedside gastric ultrasonography. Adult patients scheduled for elective surgery under general anesthesia will undergo gastric ultrasound examination after standard fasting. Gastric antral cross-sectional area and estimated gastric volume will be assessed and compared according to HbA1c levels.
The findings of this study may help improve preoperative risk stratification for aspiration and support individualized anesthetic management in patients with impaired glycemic control.
Eligibility
Primary outcome measure(s)
- Gastric emptying assessed by gastric ultrasound — The preoperative period,immediately before induction of anesthesia
Gastric emptying will be assessed preoperatively using bedside gastric ultrasonography by measuring gastric antrum cross-sectional area and estimating gastric volume with validated ultrasound-based methods.
