OBJECTIVE : Screening for congenital heart defects relies on ultrasound antenatal
and postnatal physical examination, however sometimes life-threatening defect is not
detected. We tested the accuracy of pulse oximetry as a screening test for
congenital heart defects.
METHOD : This study was aimed to obtain the profile of CHD in the Neonatal
Intensive Care Unit (NICU) of Prof. Dr. R. D. Kandou Hospital Manado collection
CHD screening results including pulse oximetry saturation value pre and postductal
analyzed in accordance with the third threshold pulse oximetry, ? 90, ?92 and ?95%.
Neonati of 276, 208 clinically well when it arrives, without comorbidities, gestation>
34 weeks and birth weight> 1.8 kg. A retrospective cohort study using medical
record data of patients suffering from CHD confirmed by echocardiography in the
period 2018.
RESULTS : There were 27 neonates with congenital heart disease, consist of
88,89% non-cyanotic CHD and 11.11% cyanotic CHD. The most common heart
defect was atrial septal defect (62.96%). Proportion of detected CHD in initial
screening was significantly higher in ?95% oxygen saturation subgroup (72% [95%
CI 66-78]) compared to ?92% oxygen saturation subgroup (46% [95% CI 39-52]).
Low oxygen saturation was found in aortic stenosis, coarctacio aorta, and pulmonary
stenosis.
CONCLUSION : Pulse oximetry is a safe and easy which adds to the value of
screening at this time. It can identify cases of critical congenital heart defects that are
not detected during antenatal ultrasonography. Early detection of other diseases is
an additional advantage. This study can assist in the development of pulse oximetry
screening policies.
