Background and Objective: There is some degree of hypoxia in many cyanotic heart diseases that cannot be diagnosed with the naked eye. The measurement of arterial blood oxygen saturation at birth is a convenient and valuable procedure. Therefore, the present study aimed to investigate the arterial blood oxygen saturation of healthy newborns and its relationship with the family history of congenital heart disease and maternal demographic variables.
Materials and Methods: In this cross-sectional descriptive study, 120 healthy neonates were selected via the convenience sampling method. Upon discharge, right-hand pulse oximetry was performed on the subjects. In the case of 90%-95% arterial blood oxygen saturation, one hour later, control was performed again. With a similar result, a referral to a cardiologist was made. Data were analyzed in SPSS software using descriptive and inferential (linear and multivariate regression) tests.
Results: The mean arterial oxygen saturation of neonates was 98.13±1.95%. The number of deliveries and the history of heart disease in first-degree relatives had a significant relationship with the saturation results (P<0.05). For each increase in delivery, the mean saturation increased by 0.591 units, while it decreased by 1.948 units with a positive history of the disease. Gestational age, gender, maternal age, and type of delivery had no significant effect on saturation (P<0.05).
Conclusion: Apart from physical examination, pulse oximetry is helpful for the early detection of congenital heart diseases that are asymptomatic at birth. Due to the importance of diagnosing these diseases, it is recommended to be routinely examined at birth.
