Statistical methods / analysis
T test, Mann-Withney U test, Wilcoxon, Kruskal-Wallis, one-way ANOVA, and Tukeys post hoc test.
At the time the study was planned there was no available data regarding the variation in selenium concentration in critically ill children. In addition, in Sweden there is no information of the selenium concentration in healthy children. Sixty healthy patients were used as controls/reference.. This information was crucial for the study and also important to know since the soil in Sweden has a low content of selenium and to evaluate if the selenium concentration was age dependent.
The main reason for choosing 100 critically ill patients was to generate a sufficient number of patients at day 5. In Scandinavian PICUs approximately 30 % of the patients have a PICU-stay > 5 days. The median stay is 2 days. We only included patients with an expected PICU-stay of > 2 days. Therefore, we expected 45/100 patients with a PICU-stay > 5 days.

Summary
Brief summary
Reduced serum selenium concentration is common in adult critically ill patients and correlates to increased morbidity and mortality. Parallel supplementation has in a few studies shown reduced mortality rate and less infectious complications. Pediatric critically ill have not been studied and normal values for Scandinavian pediatric population is not known. Selenium supplementation in premature neonatal have shown less infectious complications. In this study we aim to characterize the normal serum concentration of selenium in healthy children to be commenced for elective surgery (n=60). In parallel pediatric critically ill including newborns (n=100) will be characterized concerning selenium- and glutathione status. This approach might reveal anti-oxidative capacity and mechanisms. Secondary aims are to investigate if the selenium- and glutathione profiles correlate to length of stay and severity of illness (PELOD, PIM2).
