Comparison of Cerebral Oximeter and Pulse Oximeter Values in the First 72 Hours in Premature, Asphyctic and Healthy Newborns

Abstract

Aim: The monitoring of oxygenation is essential for providing patient safety and optimal results. We aimed to determine brain oxygen saturation values in healthy, asphyctic and premature newborns and to compare cerebral oximeter and pulse oximeter values in the first 72 hours of life in neonatal intensive care units. Methods: This study was conducted at the neonatal intensive care unit (NICU) of Van Yuzuncu Yil University Research and Administration Hospital. Seventy-five neonatal infants were included in the study (28 asphyxia, 24 premature and 23 mature healthy infants for control group). All infants were studied within the first 72 hours of life. We used a Somanetics 5100C cerebral oximeter (INVOS cerebral/somatic oximeter, Troy, MI, USA). The oxygen saturation information was collected by a Nellcor N-560 pulse oximeter (Nellcor-Puriton Bennet Inc, Pleasanton, CA, USA). Results: In the asphyxia group, the cerebral oximeter average was 76.85 +/- 14.1, the pulse oximeter average was 91.86 +/- 5.9 and the heart rate average was 139.91 +/- 22.3. Among the premature group, the cerebral oximeter average was 79.08 +/- 9.04, the pulse oximeter average was 92.01 +/- 5.3 and the heart rate average was 135.35 +/- 17.03. In the control group, the cerebral oximeter average was 77.56 +/- 7.6, the pulse oximeter average was 92.82 +/- 3.8 and the heart rate average was 127.04 +/- 19.7. Conclusion: Cerebral oximeter is a promising modality in bedside monitoring in neonatal intensive care units. It is complementary to pulse oximeter. It may be used routinely in neonatal intensive care units.
