INS and Hyperglycemia: Verhoeven et al reported hyperglycemia in 52% of children after surgery.5 Accordingly, Moga et al demonstrated hyperglycemia in 90% of their study patients; however, hyperglycemia diminished without insulin administration 72 hours after surgery.4 Falcao et al illustrated slight and severe hyperglycemia in patients (97% and 78%).12 In Preissig et al study, hyperglycemia prevalence was 84%.13 Hyperglycemia prevalence was lower in our study than mentioned studies in which the patients were either given insulin or not.
