Abstract
Objective: To study the comparison of fasting gastric volume using ultrasound in diabetic and nondiabetic patients in elective surgeries. To compare the incidence of delayed gastric emptying in diabetic and nondiabetic after standard fasting guidelines Material and Methods: After institutional ethical committee approval, CTRI registration and patient consent, prospective study was conducted in 30 diabetic and 30 non-diabetic patients aged 30-60years of American society of anesthesiologists- physical status I-III having similar fasting intervals. Pre operatively, quantitative assessments of gastric antrum in supine and right lateral decubitus (RLD) positions were performed using curvilinear probe in accordance to standard gastric scanning. USG grade, cross-sectional area (CSA) of the antrum and gastric volume were calculated. The gastric antrum was classified as Grade 0, 1 or 2, signifying empty antrum, fluid in RLD position only and antral fluid in both supine and RLD positions, respectively. Results:The CSA of 2.35 ± 1.07 cm2 and 3.51 ± 1.4 cm2 in diabetic were significantly higher (P = 0.001) than 1.37 ± 0.32 cm2 and 2.19 ± 1.15 cm2 of control, in supine and RLD positions, respectively. GV was 3.85± 20.06 ml in control group and 6.5±23.51 ml in diabetic group. Conclusion: Diabetic patients have higher gastric antral cross-sectional area and gastric volumes as observed by gastric ultrasound than the non-diabetic patients. Reference - 1.
