Abstract

This study assessed the effectiveness of preoperative oral carbohydrate loading on insulin
resistance in patients undergoing ventricular septal defect surgery in Vietnam National Children’s
Hospital. A total of 36 patients aged 2 months to 12 months undergoing ventricular septal defect surgery
were enrolled and randomized into two treatment groups: one group received 12.5% carbohydrate
loading 2 hours and the other group were instructed to fast for 4-6 hours before surgery. The clinical
characteristics and laboratory tests were evaluated both at before and after surgery. The postoperative
glucose and insulin concentrations were lower in the intervention group than the control group. The
postoperative HOMA-IR and QUICKI significantly improved in the intervention group (p=0.007).
There was no incidence of lung aspiration in the intervention group. The results suggested that
preoperative oral carbohydrate loading was safe and effective in reducing patient’s insulin resistance.
