Description of intervention(s) / exposure
The main objective of this observational study is to investigate if normoglycemia is maintained when a near isotonic maintenance fluid containing 1 % glucose is given intraoperatively to infants (1-12 moths of age). (n=375).
The administered 1% glucose near-isotonic maintenance fluid will be given as a continous infusion during the whole intraoperative period ,5 ml/kg/hour for minor surgery, 7 ml/kg/hour for moderate surgery and 10 ml/kg/hour for major surgery. This is the only intravenous maintenance fluid that will be given intraoperatively. Using near-isotonic 1% glucose solution for this age group is not yet clinical practice at our department , mostly due to fear of hypoglycemia. However, this solution is widely recommended, including European Society of Pediatric anesthesia. This study focus upon a specific age cohort with possible risk of hypoglycemia. and include a relatively large number of patients. We believe that the recommendations can be substantiated with the results from this study.
Plasma glucose concentration (blood-gas analysis) will be determined at induction of anesthesia and then every 30 minutes during surgery.
In the blood-gas analysis also sodium will be analysed.
The concentration of ketone bodies will be measured at induction and at the end of surgery.
The time of fasting will be determined and related to glucose- and ketoneconcentration.
In a subgroup of subjects undergoing major surgery with expected duration > 60 minutes, endogenous glucose production and energy production will be determined using stabile isotope (6.6-D2-glucose) and indirect calorimetry respectively.

Endogenous glucose production rate. This will be investigated in a subgroup of subjects undergoing major surgery with expected duration > 60 minutes. Endogenous glucose production will be determined using stabile isotope (6.6-D2-glucose).
Timepoint [1] 367960 0
The stable isotop 6.6-D2-glucose will be given as a prime - constant infusion during anesthesia/surgery. In parallell, glucose from the near-isotonic glucose infusion is given at a known rate. At later analysis the quotient 6.6-D2-glucose/glucose will be determined. Thereby endogenous glucose production can be determined.

Energy production will be determined using indirect calorimetry.

Investigation of energy production will be performed 30 to 60 minutes after anesthesia induction.

Statistical methods / analysis
Power calculations are based on possible incidence of hypoglycemia occurring intraoperatively to infants (1-12 months) undergoing surgery given near-isotonic maintenance fluid containing 1 % glucose at a infusion rate of 5-10 ml/kg/hour. If patients (n=375) are investigated, this will result in a 95 % confidence intervall of (0-0.012) assuming a proportion of 0.999. Assuming that the proportion of patients that will develop hypoglycemia (< 3.0 mmol/L) is 1/1000 and none of the patients in the study (n=375) develop hypoglycemia, It can be assumed that the risk of developing hypoglycemia is maximally 1 %. This is hypothetical since the true incidence of hypoglycemia under these conditions are and will remain unknown. However, given that no patient in this study develop hypoglycemia, the resulting confidence interval will be 0.01, that is from 0.99 to 1.0. The risk of the incidence being outside this interval is 5 %.
Data will be tested for normality using D’Agostino & Pearson omnibus normality test. Parametric or non-parametric statistics will be used as appropriate to investigate differences in glucose-, ketone- and sodium concentration from induction of anesthesia to end of surgery.

Summary
Brief summary
European guidelines for intraoperative maintenance fluid recommend a near-isotonic solution containing 1-2.5 % glucose. In most European countries, a near-isotonic solution containing 2,5 % glucose is not available. This necessitates anesthetic personal to add extra sodium to the solution. This may be hazardous – risk of adding wrong electrolyte, risk of infection etc. On the other hand, a commercial near-isotonic 1 % glucose solution is available. However, there are limited safety data for the risk of developing hypoglycemia for infants when 1 % glucose are given intraoperatively. Furthermore, basic knowledge of intraoperatively glucose metabolism are lacking. This study will considerably strengthen safety data for using a 1 % glucose solution. In addition, the study will provide new information of intraoperative endogenous glucose production, energy production and importance of duration of fasting for glucose metabolism intraoperatively.
