In this study, the investigators aimed to evaluate the gastric antrum with ultrasound and compare gastric volumes in diabetic and non-diabetic pregnant women in the standard fasting state before surgery. The primary aim was qualitative assessment, while secondary objectives included quantitative assessment, comparing gastric volume, aspiration risk, and the effect of preoperative anxiety on stomach contents.
Food residues in the stomach of patients scheduled for surgery are a major risk factor for pulmonary aspiration, leading to significant morbidity and mortality. This risk is particularly critical in pregnant women who may require surgery without proper fasting. National guidelines recommend fasting for 6 hours for solid foods, 4 hours for breast milk, and 2 hours for clear liquids. These guidelines apply equally to adults and children. Pregnant patients scheduled for elective surgery follow the same fasting rules as non-pregnant patients. Gastroparesis, defined as delayed gastric emptying without mechanical obstruction, affects 30-50% of diabetic (DM) patients. Ultrasound measurement of the gastric antral area can help identify whether the stomach is full in symptomatic patients. Gastric ultrasound is a valuable tool for assessing aspiration risk in pregnant women, especially during emergency surgeries, and has shown promise in fasting non-pregnant patients scheduled for elective surgery. In this study, the investigators aimed to evaluate the gastric antrum using ultrasound and compare gastric volumes in diabetic and non-diabetic pregnant women in a standard fasting state before surgery. The primary goal was qualitative assessment, with secondary objectives including quantitative assessment, comparing gastric volume, aspiration risk, and the effect of preoperative anxiety on stomach contents.

Gastric Antrum Quality
Qualitative evaluation of the gastric antrum using ultrasound: For the qualitative evaluation of the gastric antrum, we used a grading scale where the gastric antrum is classified as Grade 0, 1, or 2. The grading criteria are as follows: Grade 0: The stomach appears empty in both supine and right lateral decubitus positions. Grade 1: The stomach appears empty in the supine position but shows clear fluid in the right lateral decubitus position. Grade 2: Clear fluid is seen in the stomach in both supine and right lateral decubitus positions.
Time frame: 12 months
Gastric Volume
Quantitative measurement of gastric volume in milliliters.
Time frame: 12 months
Aspiration Risk
Number of participants with a high aspiration risk based on gastric volume.
Time frame: 12 months
Preoperative Anxiety Effect
Measurement of stomach content volume related to preoperative anxiety levels.
Time frame: 12 moths
