About this trial
Although there are fasting guidelines offered by the American Society of Anesthesiology (ASA) for managing preoperative patient assessment, some patients may need to be more cautious about the risk of aspiration. Since ultrasound has been a part of perioperative anesthesiology practice, it is simple to assess gastric content preoperatively with bedside ultrasonography (USG). More research is necessary to define elective surgeries with a possible risk of aspiration. Therefore, we aimed to evaluate the adequacy of standard fasting protocols in post-traumatic fracture surgery by measuring and evaluating gastric volume and content with USG in the preoperative operating room.

Gastric ultrasound
Diagnostic testPreoperative gastric antrum examination to detect gastric content (empty, liquid, or solid) and measure gastric volume
Treatment groups
Trial outcomes
Primary outcomes
gastric volume(ml)
gastric volume calculated with gastric volume (mL) = 27.0 + 14.6 x right-lat CSA - 1.28 x age and Antral cross-sectional area = anterior posterior diameter (D1) × cranio-caudal diameter (D2) × π/4 . Evaluation is done as over 1,5 ml /kg grade 2; if 1,5- 0,8 ml/kg, grade 1; ˂ 0,8 ml/kg, grade 0
gastric content
Grade 0, no gastric content within the antrum at both positions ( supine and right lateral decubitis(RLD)); Grade 1, gastric content is seen only at RLD position; Grade 2 gastric content was detected in both positions
Secondary outcomes
nausea or vomiting
postoperative nausea or vomiting
aspiration pneumonia
fever, cough, tachypnea, tachycardia within and if there is any of these has occured, aspiration pneumonia will be searched with further examination or imagination for certain diagnosis
