The value of transcutaneous oxygen saturation in early diagnosis of newborns with critical congenital heart disease / 中国新生儿科杂志

ABSTRACT

Objective To study the value and significance of transcutaneous oxygen saturation monitoring from different parts in early diagnosis of neonatal critical congenital heart disease. Methods The transcutaneous oxygen saturation in right upper extremities and right lower extremities of neonates born in our hospital from July 2010 to July 2015 were detected at 2 hours to 24 hours after birth. If the transcutaneous oxygen saturation ≤ 0. 95 or difference between upper and lower extremities≥0. 03, color doppler ultrasound echocardiography were done. Results There were 24 385 cases of newborns in our study. 1 680 newborns with abnormal transcutaneous oxygen saturation ( ≤0. 95 or difference between upper and lower extremities ≥0. 03) were examined with color doppler ultrasound echocardiography. 204 cases of congenital heart disease (12. 1% ) contain 9 cases of critical congenital heart disease ( 0. 5% ) were detected. The critical congenital heart disease included complete transposition of great artery ( n = 3), tetralogy of Fallot ( n = 4), artery malformation ( n = 1), and pulmonary atresia with right ventricular dysplasia ( n = 1 ) . Conclusions Transcutaneous oxygen saturation monitoring from different parts has a high value for early detection of critical congenital heart disease in the newborn. It is recommended for clinical use in grass-roots hospitals.
