The present study investigates the possibility of detecting changes in cerebral oxygenation and consequently of intraventricular hemorrhage (IVH) in preterm children using paired data from the NIRS-monitor and the patient vital signs monitor. During the study, one patient's data were analyzed. The patient was born at the gestational age of 25+6 weeks. He was monitored for a period of 72 hours. IVH was first detected by the ultrasound diagnostics in 1000 minutes after birth. Analysis of the paired data showed that HR is not a useful IVH indicator. Comparison of the regional cerebral (cSrO2) and peripheral blood oxygen saturation (SpO2) changes and cerebral fractional oxygen extraction (OEF) with its second derivative represents a more beneficial method. It shows the tissue oxygen absorption changing (ie, periods of great change in hemodynamic, at the beginning or end of IVH). By comparing the calculated results and the medical records of the IVH course, it can be argued that this method can be efficiently used to determine the start and end of the bleeding into the brain ventricles.
