Background: There is no clear consensus on preoperative fasting times in pregnant and diabetic patients. The primary objective of this study is to compare the estimated gastric volumes calculated by gastric antral cross-sectional area (CSA) and 2 mathematical models under gastric ultrasonography in fasting diabetic and non-diabetic term pregnant women scheduled for cesarean surgery. The secondary objective is to determine the relationship between demographic and clinical variables and gastric antral CSA values in these pregnant women. Methods: Pregnant women who were planning elective cesarean birth and kept fasting in accordance with preoperative fasting guidelines were included in the study. The classifications of gastric contents in patients' supine and right lateral positions (Grade 0–2), antral CSA values, and gastric volumes calculated with the Perlas equation and the Roukhomovsky equation were recorded. Two groups were formed as diabetic (Group D, n = 29) and non-diabetic (Group C, n = 30). Results: The values of the average supine and right lateral antral CSA were statistically significantly higher in Group D than in Group C. According to the Roukhomovsky equation, the average residual gastric volume values of Group D were statistically significantly higher than Group C. According to the multiple linear regression analysis results, only BMI had an effect on CSA. It was found that for every 1 unit increase in BMI, CSA increased by 0.285 units. Conclusion: It was determined that gestational diabetes was not a risk factor for increased residual gastric volume, and the only statistically significant risk factor according to the multiple regression analyses was BMI.
