RESUMO
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.

BACKGROUND: During general anesthesia, core temperature decreases, largely due to heat loss caused by peripheral vasodilation, resulting in heat redistribution to peripheral tissues. Multiple factors contribute to body temperature regulation during general anesthesia. It was reported that baroreceptor unloading by positive end-expiratory pressure (PEEP) attenuates anesthetically-induced hypothermia. So, we evaluated the effects of PEEP on thermoregulatory responses during total intravenous anesthesia (TIVA). METHODS: Forty healthy patients scheduled for tympanoplasty were allocated two groups, Group ZEEP (zero end-expiratory pressure, n = 20) and Group PEEP (PEEP application of 5 cmH2O, n = 20). Ambient temperature was maintained at 22-24degrees C, and anesthesia was induced and maintained with propofol-remifentanil. The core temperature and the temperature difference between forearm and fingertip skin were monitored before and after the induction of general anesthesia having a duration of 180 minutes. RESULTS: The core temperature gradient (Ti-Tf) was higher in patients with ZEEP than with PEEP. The core temperature was maintained at a higher level in patients with PEEP. Additionally, the vasoconstriction threshold was higher in patients with PEEP. CONCLUSIONS: It seems that PEEP attenuates anesthetically-induced hypothermia during TIVA.
