Abstract

BACKGROUND: Whether intraoperative fluid therapy should contain glucose for the pediatric outpatient surgery remains controversial. This study was designed to compare the effects of glucose and glucose-free solutions on perioperative blood glucose change.
METHODS
Healthy pediatric outpatients (n = 130) for minor procedure were randomly assigned to one of two fluid therapy groups. Patients in the group H (n = 65) received lactated Ringer's solution, and patients in the group D (n = 65) received 5% dextrose perioperatively. Blood glucose was checked before infusion (a), 10 minutes after induction (b), 30 minutes after induction (c), and at the time of discharge (d).
RESULTS
The preoperative fasting glucose concentrations were 97.6 +/- 12.1 mg/dl and 97.7 +/- 11.3 mg/dl for the group H and D, respectively. The patients in the group D showed significantly increased blood glucose level after induction (135.9 +/- 42.7, 150.3 +/- 36.0, 123.6 +/- 26.8 mg/dl). The patients in the group H also showed significantly increased blood glucose levels (112.2 +/- 14.0, 121.4 +/- 11.4 and 105.8 +/- 18.3 mg/dl). The glucose level of group D was significantly higher than the glucose level of group H at b, c and d. Seven patients in the group D showed hyperglycemia (> 200 mg/dl).
CONCLUSIONS
Dextrose containing fluid therapy resulted dangerous hyperglycemia in the pediatric outpatient surgery. We recommend lactated Ringer's solution or other glucose-free crystalloid for the healthy outpatient pediatric population undergoing minor procedures.
