Residual Gastric Volume Measured by Ultrasound in Diabetic Surgical Population Versus Non-diabetic Surgical Population.

Comparative Observational Study of Residual Gastric Volume Measured by Ultrasound After Preoperative Fasting in a Diabetic Surgical Population Versus a Non-diabetic Surgical Population.

Comparison of residual gastric volume measure by ultrasounds between diabetic and non-diabetic patients scheduled for elective surgery

The presence of gastric content increases the risk of aspiration during general anesthesia. Delayed gastric emptying has been described in diabetic patients; for that reason, diabetic patients could have a high risk of aspiration despite adequate fasting. This study aimed to compare ultrasound-guided measurement of residual gastric volume between diabetic and non-diabetic patients scheduled for elective surgery.

Inclusion Criteria:

• BMI<40 kg.m-2;
• Age over 18 years;

• who were to undergo elective surgery and had the ability to understand the rationale of the study and provide informed consent

Exclusion Criteria:

• Pregnancy
• Recent upper gastrointestinal bleed (< 1 month)
• Abnormal anatomy of the upper gastrointestinal tract (such as hiatal hernias and gastric tumors)
• Previous surgical procedures on the esophagus, stomach, or upper abdomen
• Gastroesophageal reflux disease
• Previous use of prokinetics or high doses of opiates.
