Baseline Gastric Volume in Diabetic vs Non-Diabetic Patients

Condition(s) studied

Investigational drug(s) / intervention(s)

Gastric Ultrasound: Preoperative gastric ultrasonography will be performed to assess gastric antral cross-sectional area and estimate residual gastric volume in patients scheduled for elective surgery. The examination will be performed in the supine and right lateral decubitus positions using a low-frequency convex probe by experienced anesthesiologists.

Study summary

During the preoperative preparation process, the fasting period for anesthesia is planned according to guidelines. According to standard guidelines, a fasting period of at least 2 hours is recommended for clear liquids, at least 6 hours for light meals, and at least 8 hours for a full meal. However, it has been reported that these guidelines are valid for healthy patients. It is thought that the planned fasting periods may vary in diabetic patients due to delayed gastric emptying. This study aims to calculate gastric volume under ultrasonography guidance and compare it with fasting time.

Eligibility

Primary outcome measure(s)

• Preoperative residual gastric volume — Preoperative period
  Assessment of whether standard preoperative fasting guidelines provide an empty stomach in diabetic patients by comparing estimated residual gastric volume measured with gastric ultrasonography between diabetic and non-diabetic patients scheduled for elective surgery
