Relationship between blood glucose levels and fluids administered during perioperative period in fasted children

ABSTRACT

BACKGROUND: Fasting during the preoperative period is known to be a risk of perioperative hypoglycemia. Also, the administration of fluids containing glucose often causes postoperative hyperglycemia. So, we investigated what is the ideal fluid which does not lead to hyperglycemia as well as hypoglycemia in fasted children. METHODS: Eighty ASA physical status I and II pediatric patients (1-7 years) were randomly divided into the four groups; Group I, II, III, and IV with twenty patients of each group. Patients in Group I, II, III, and IV received lactated Ringer's solution, 1 2 3 SD solution, 1 2 SD solution, and 1 3 SD solution, respectively during the perioperative period. Blood glucose levels were checked at pre-induction, 1 hr after induction and 1 hr, 4 hr, 8 hr after end of operation. NPO time and total amounts of fluids administered were measured. RESULTS: There was no patient with preoperative hypoglycemia. There were no significant differences in the perioperative blood glucose level among the groups. There was no relationship between blood glucose level and fasting time or age. CONCLUSIONS: We conclude that all of the four fluids with different glucose concentrations in this study were appropriate to the fasted children.
