Diabetic Gastric Residual Volume

A study of 50 patients using both gastric ultrasound and nasogastric aspiration compared patients with diabetes for more than 6 years with healthy controls, after undergoing anesthesia for elective surgery. Patients with long standing diabetes showed higher residual gastric volume compared to healthy controls after fasting 8 hours for elective surgery, confirming most anesthesiologists’ beliefs. This may alter the NPO approaches to such patients as well as the anesthetic technique, although whether these findings affect complication rates or outcome is not addressed.
