Abstract
Objective. To analyze results of pulse oximetry screening in Tatarstan Republic in 2020–2022, estimate age on the day of correction of critical congenital heart defects (CCHD) in newborn with positive screening results and compare this data with the groups of prenatal and delayed diagnosis.
Material and methods. We analyzed cases of newborns with CCHD for 2020 and 2021. We divided patients into 3 groups: 1 – prenatal diagnosis (CCHD was diagnosed prenatally, 27 cases), 2 – screening group (CCHD was diagnosed after positive screening result, 15 cases), 3 – group of delayed diagnosis (CCHD was an accidental finding after discharge, 4 cases).
Results. Neonates from group 1 and 2 went through correction significantly earlier than patients from group 3 (p=0.009, p=0.01 respectively). Average age on the day of correction in groups 1, 2 and 3 was 5, 7 и 51,5 days respectively. No significant difference was found in in-hospital stay duration between groups.
Conclusion. Pulse oximetry screening in addition to prenatal ultrasound screening detects more than 30% additional patients with CCHD before discharge. Patients with positive screening results are going through surgical correction in earlier age.
