Description of intervention(s) / exposure
The patients were interviewed the night before the operation and were told to record what they ate and when. The last laboratory values of the patients registered in the system were recorded. The patients were instructed not to smoke for at least 8 hours before the measurement.Gastric antrum measurement with ultrasound was measured in the premedication chamber within the last hour before surgery. Gastric antrum measurement was performed in the premedication room by ultrasound in the supine and right lateral decubitus positions, taking into account the anatomical reference points before the patients were taken into operation.
Ultrasound evaluation training was provided by the radiology team and at least 40 patients were evaluated with gastric ultrasound.Measurements were made by a single anesthesiologist.
Measurements were made 3 times in about 15 minutes before the operation,the average was taken .

Statistical methods / analysis
Data analysis will be done using SPSS 22.0 program. Continuous data normal with Shapiro-Wilk test
will be evaluated in terms of distribution and, according to the distribution, the mean (standard deviation) or median (quartiles)
will be expressed as the gap. Data with normal distribution between groups were determined by t-test.
non-distribution will be tested with Mann-Whitney. For categorical data, chi-square or
Fisherexact test will be used. Independent risk factors with p <0.1 will be included in logistic regression analysis

Summary
Brief summary
In this study; it is aimed to investigate on factors affecting low and high-risk
groups in terms of aspiration by measuring gastric volume with ultrasound in
diabetic patients who fasted for elective surgery.
After obtaining written informed consent from patients with diabetes mellitus, who will undergo elective surgery, day/night before surgery.
Then, the appropriate fasting time will be explained to the patient and they will be asked to record the last meal (solid and liquid) they ate.
Detailed anamnesis was taken, demographic data in the case report form, drugs used, accompanying
diseases, duration, type and complications of diabetes will be questioned.
Fasting times on the morning of the surgery will be questioned again and recorded. Low frequency (2-5 With the MHz) curved probe, patients were first in the supine position and then in the right lateral position for five minutes. The measurement will be made by keeping it waiting.Gastric antrum will be displayed. Left lobe of liver and head of pancreas as anatomical reference points. Inferior vena cava and abdominal aorta will be taken. Qualitative and quantitative measurements will be made. Qualitative grade 0 if the antrum is small, the anterior-posterior wall is close to each other, thick and the contents are not visible; wall thin and only if clear fluid is seen in the right lateral position grade 1; wall thin and clear hypoechoic or If the anechoic fluid appears in both the supine and right lateral positions, it will be considered grade 2. Quantitative Crosssectional area (CSA) will be measured with ultrasound using the two-dimensional method.
Antrumanteroposterior (AP) and craniocaudal (CC) measurements will be made from serosa to serosa of the antrum and it will be calculated according to the formula CSA=(AP x CC x pi number)\4. Measuring 3 times CSA and its average Then, according to the PERLA formula, GV (ml)=27.0+14.6 x right lateral CSA (cm2) -1.28 x age (years) gastric residual volume will be calculated. Threshold value for gastric volume content, which will pose a risk for aspiration, is 1.5 ml/kg will be accepted. Grade 0 low risk, if we see solid food in the content, high risk, liquid food in the content grade 1 or volume < 1.5 ml\kg, low risk; Grade 2 or high risk if the volume is >1.5 ml\kg .Measurements will be taken with a US instructor prior to the study, and experience will be taken by measuring 50 times will be carried out by the researcher. The last measured FBG(fasting blood glucose) HbA1C, creatinine value by scanning the hospital computer system will be recorded. In terms of risk factors, the patients evaluated as full stomach and those evaluated as empty stomach will be compared.
