Gastric Volume in Diabetic Patients after Overnight Fasting vs Clear Liquid Ingestion Two Hours before Surgery Using UltraonographyA Randomised Clinical Trial
Abstract
Introduction: Perioperative gastric aspiration poses risks such as aspiration pneumonia, prolonged hospital stays, and increased mortality. Fasting guidelines may not adequately address the needs of diabetic patients due to the delayed gastric emptying often observed in this population. Aim: To assess residual gastric volume in diabetic patients who fasted overnight versus those who ingested water preoperatively using ultrasound. Materials and Methods: A randomised clinical trial enrolled 50 diabetic patients undergoing elective surgery. Patients were randomised into two groups: fasting overnight or receiving water preoperatively. Gastric ultrasound was used to measure antral dimensions and calculate gastric volume. The parameters studied included residual gastric volume in diabetic patients in the Right Lateral Decubitus (RLD) position, antral CrossSectional Area (CSA) in the semi-sitting position among diabetic patients, and antral CSA in the RLD position among diabetic patients. Statistical analysis involved descriptive statistics for continuous variables and Chi-square tests for categorical variables, with significance set at p-value<0.05. Results: The study enrolled 50 diabetic patients, with 25 in group A and 25 in group B. The mean age of patients in group A was 49.3±11.7 years, while in group B, it was 58.6±9.8 years. In the RLD position, the mean Craniocaudal (CC) diameter showed no significant difference between the two groups. However, the mean Anteroposterior…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 50 participants or records.
