Comparison of Pulse Oxymeter and Cerebral Oxymeter Values in Healthy Newborns in the First Five Minutes of Life

Abstract

Objective: Practical approaches in delivery rooms have been discussed about oxygen usage in recent years. In this study, it was aimed to correlate preductal arterial oxygen saturation (SpO(2)), heart rate per minute and serebral oxygen saturation (SbO2) values of first five minutes of life and to try the pulse oxymeter (PO) and cerebral oxymeter (SO) usage practice in delivery room. Material and Method: A hundred healthy term uncomplicated newborn babies, who were born via normally spontan vaginal route, were included in the study. SpO(2), SbO2, heart rate measurements and blood gase analysis of first five minutes of postnatal life were completed. Babies, who needed oxygen during measurements, were not taken in to the study.. Results: While postnatal 1st minute SpO(2) value was 83.0 +/- 4.4 (74-94)%; at 5th minute these measurements reached to 92.9 +/- 3.5 (85-98)% with gradually increment. Except values of 4(th) and 5(th) minutes; SpO(2) values were found statistically significant high with each other (p<0.05). At SbO2 measurements, suitable data was taken from 100% of the babies in first minute of life. While postnatal mean SbO2 value of the first minute was 48.9 +/- 9.9 (32-74)%; these measurements were reached to 69.9 +/- 9.5 (46-89)% at 5th minute gradually increment as like as SpO2 values. Conclusion: SO is complementary to PO in delivery room and can be used routinely. It was seen also in our study; oxygen need of newborns can be determined faster and more accurately with SO use in delivery room so unnecessary oxygen usage and its potential risks can be avoided..
