Abstract
Objective: To evaluate pulse oximetry for detection of congenital cyanotic heart disease in sick neonates using echocardiography as gold standard. Methods: Pulse oximetry readings were taken at admission from 500 neonates from right upper limb and either foot with infant breathing room air. Pulse oximetry was considered abnormal if oxygen saturation at room air measured <90% or difference between right hand and foot was more than 3%. Persistent abnormality was considered positive result. Echocardiography was performed on all neonates with positive pulse oximetry (study group) as well as on neonates with negative pulse oximetry (controls) . Results: Pulse oximetry was positive in 24 neonates. It detected 9 out of 10 (90 %) true positives. The sensitivity, specificity, positive predictive value, negative predictive value and odds ratio (95% CI) of pulse oximetry was 90 %, 55.58 %, 5.62 %, 99.47 and 11.3 , respectively. Conclusion: Pulse oximetry screening is useful in detecting cyanotic heart disease. Congenital heart diseases (CHDs) account for 6 -10 % of all the infant deaths, and 20 - 40 % of all infant deaths from malformations [1]. About 25% of CHDs are life threatening and manifest before the first routine clinical examination [1,2]. The existing pulse oximetry monitoring protocol to detect critical congenital heart disease, is restricted to neonates in infant nursery [5] . Pulse oximetry as a screening test for congenital cyanotic heart disease has been evaluated among in sick neonates. The present study was designed to evaluate the utility of pulse oximetry screening in detecting congenital cyanotic heart disease among sick neonates in a referral neonatal unit catering to outborn neonates
