Purpose: To evaluate the results of the pulse oximeter screening for the early diagnosis of critical congenital heart defects in newborns in our hospital and to share our results before the implementation of a nationwide screening program. Methods: This was a retrospective study on 2261 infants between April 2018 and January 2020. Right-hand for preductal measurement and right or left foot for post-ductal measurement were measured using Nellcor pulse-oximetry (Covidien, MA, USA). Results: In 2261 newborns, the average birth week of 2261 infants was 38.05±1.32 weeks and 3204.21±478.28 g birth weight. The mean screening time was 25.9±7.3 hours (median 25 hours; min–max 7–96 hours). The mean values of the pre-ductal and post-ductal measurements of the infants who passed the test at the first measurement were 96.46±1.65 and saturation 95.99±1.49. 2247 (99.38%) of the infants included in the study underwent screening, 14 (0.61%) could not pass. Overall test false positive rate was 0.6% for critical congenital heart defects. Critical congenital heart defects was not seen in any of those who could not pass the scan. Sensitivity and positive predictive value could not be calculated, as no critical congenital heart defects case was detected. Specificity and negative predictive value of the pulse-oximetry test were 99.3% and 100% respectively. Conclusion: We highlight that screening with pulse-oximetry should be popularized particularly in peripheral regions providing secondary health care services. We are of the opinion that screening of critical congenital heart defects with pulse-oximetry should be included in the national screening program in our country.
