The prevalence of iron deficiency in pediatric cardiac surgery patients is not very well known. Iron deficiency can lead to anemia, higher transfusion rates and possibly higher complication rates. In this retrospective study, the iron status of all patients undergoing pediatric cardiac surgery at our institution between January 2019 and december 2023 will be analyzed. Together with iron status, transfusion requirements as well as complications will be recorded. Iron status will be reported with descriptive statistics, patients with or without iron deficiency will be compared using non-parametric tests.
Study Type
OBSERVATIONAL
Enrollment
300
Iron status will be based on preoperative ferritin levels: a ferritin \< 10 mcg/L will be considered as iron deficiency, ferritin levels \> 10 mcg/L will be considered normal

Brussels, Belgium
RECRUITINGPrevalence of preoperative iron deficiency (%)
A preoperative ferritin \< 10 mcg/L will be considered as iron deficiency. Iron deficiency will be reported using descriptive statistics (mean, standard deviation, median, interquartile range, %)
Time frame: 24 hours
Complications
The complication rate (%) will be reported. Complications are defined by the occurence of one or more of the following events: * transfusion rate (%) * volume of packed red cells transfused (mL/kg) * perioperative blood loss (mL/kg) * need for surgical re-exploration (%) * intensive care stay (days) * new renal insufficiency (%) * use of inotropes (%) * 28 day mortality (%) The frequency of any single item will also be reported (%)
Time frame: 28 days
