Randomized Study Comparing Pre-Operative Glycemic Profile in Pediatric Cardiac Surgical Patients Administered Oral Carbohydrate Solution Preoperatively versus Those Kept Fasting

Objectives: Hypoglycemia is a recognized danger in pediatric patients. Extended period of preoperative fasting in this subset of patients is not well tolerated with metabolic derangements. The oral carbohydrate loading preoperatively can ameliorate many adverse effects. The aim of this study was to compare the glycemic profile in pediatric cardiac surgical patients kept fasting preoperatively with those fed oral clear solutions of carbohydrate half hour prior to induction of anaesthesia. Also we tried to establish a correlation with other factors contributing to preoperative hypoglycemia. Methodology: We planned a randomized controlled study. Group A included patients who were kept fasting according to the ASA guidelines preoperatively and Group B included patients who received 2 ml per kg of body weight of 10% Dextrose water as oral feeds half hour before the expected time of start of anaesthesia. Results: The mean (SD) preoperative BG concentrations were higher in group B (102.5 ±16.97) as compared to group A (64.08 ± 25.37) (p value -0.86 and -0.67) (pvalue Conclusion: Preoperative oral carbohydrate preloading can develop as the easiest and cheapest path to better perioperative blood glucose concentration management in congenital cardiac disease children.
