evaluation of the effect of amino acid administration on hypothermia during general anesthesia in hypospadias surgery on children aged 2 to 6 years

background: hypothermia is an important complication during surgery, especially in children and is highly associated with serious adverse outcomes. one of the preventive methods is the intraoperative administration of amino acids, which can be effective through increasing thermogenesis and stimulating energy consumption. no studies have been conducted in this regard on children; therefore, we evaluated the preventive effect of intraoperative administration of amino acid on hypothermia in children. methods: forty children, aged 2 to 6 years, who were candidates for hypospadias surgery, were divided into two groups. in the case group, 10% amino acid (2 cc/kg/h) was administered two hours before the operation, and in the control group, normal saline was given as required. all patients underwent a similar method of anesthesia. body temperature was recorded before the anesthesia, immediately after it, and every ten minutes. results: the mean age and weight had no difference between the groups. duration of patients' awakening time was 13.60 ± 4.91 min, which in the case and control groups was reported as 11.90 ± 5.27 and 15.30 ± 3.96 min, respectively(p
