“…34,35 ). These results suggest that single site recording of the regional cerebral oxygen saturation and cerebral fractional tissue oxygen extraction can monitor trends in individual patients to detect changes larger than the limits of agreement, but lacks the precision to be used as a robust quantitative variable of cerebral oxygenation 36 37 .…”

Near-infrared spectroscopy (NIRS) is a technology capable of non-invasive, continuous measuring of regional tissue oxygen saturation (StO 2 ). StO 2 represents a state of hemodynamic stability, which is influenced by many factors. Extensive research has been done in the field of measuring StO 2 of various organs. The current clinical availability of several NIRS-based devices reflects an important development in prevention, detection and correction of discrepancy in oxygen delivery to the brain and vital organs. Managing cerebral ischemia remains a significant issue in the neonatal intensive care units (NICU). Cerebral tissue oxygenation (cStO 2 ) and cerebral fractional tissue extraction (cFTOE) are reported in a large number of clinical studies. This review provides a summary of the concept of function, current variability of NIRS-based devices used in neonatology, clinical applications in continuous cStO 2 monitoring, limitations, disadvantages, and the potential of current technology.

“…It enables monitoring of the regional tissue oxygenation, for example oxygenation of the brain tissue. [5,6] At the beginning of the 21st century in Drexel University (PA), Alper Bozkurt and his research team, having researched the principle of NIRS, assumed a possible correlation between cerebral blood flow, cerebral oxygenation, and subsequent occurrence of intraventricular / brain hemorrhage in premature infants. [7] Ying Zhang and his team analyzed the 3-hour records of 5 preterm infants with IVH and 12 preterm infants without IVH.…”

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.

“…В последние годы особое внимание исследователей и клиницистов привлекает использование с этой целью у новорож-денных детей неинвазивного, безопасного и доста-точно информативного метода параинфракрасной спектроскопии (NIRS) [1,18,19,29,42,44]. Тех-нология метода основана на способности тканей пропускать свет в близком к инфракрасному диапа-зону (длина волн 700-1000 nm) и его поглощении такими хромофорами, как оксигемоглобин (Hb0 2 ), дезоксигемоглобин (HHb), цитохром С оксидаза, для каждого из которых характерен свой спектр поглощаемых волн [14,35,52].…”

“…При этом NIRS от-ражает локальное насыщение кислорода (rS0 2 ) как динамический баланс между доставкой и потребле-нием кислорода мозговой тканью. Для вычисления количества кислорода, захваченного тканью мозга, предложена формула «фракционной тканевой экс-тракции кислорода»: FTOE = (SO 2 -rSO 2 ) / SO 2 , где SO 2 -сатурация кислорода в артериальной крови, одновременно измеряемая с помощью пульсокси-метра [44,52,53]. Церебральная оксиметрия ис-пользуется также для оценки мозгового кровотока [9,21,29] и объема крови в сосудах головного мозга в комбинации с постоянным мониторингом артери-ального давления [30,57].…”

“…Чем больше гестационный возраст ребенка, тем ниже показатели оксигенации мозга, но выше фракционная экстракция кислорода, при-чем онa коррелирует с частотой сердечных сокра-щений, дыхания и значениями SaO 2 [42,46]. Многочисленные исследования определили большое значение мониторинга церебральной ок-сигенации у родившихся в асфиксии новорожден-ных детей при оказании реанимационной помощи в родильном зале и в палате интенсивной терапии [47,48], при коррекции гемодинамических наруше-ний, закрытии артериального протока и при других критических состояниях для своевременной кор-рекции гипо-или гипероксии мозга, а следователь-но, профилактики неблагоприятных последствий [21,44,47,49]. Вместе с тем авторы указывают на значительные не только индивидуальные коле-бания показателей, но и в процессе мониторинга у каждого ребенка и подчеркивают необходимость проведения церебральной оксиметрии в сочетании с регистрацией ЭЭГ, артериального давления, пуль-соксиметрией для выявления механизмов, лежащих в основе этих изменений [33,52].…”

The frequency of disturbance the functional development of newborn brain after intrauterine and birth asphyxia determines the necessity the finding objective methods of timely diagnosis the alteration of brain oxygenation for the target therapy. During last years the special attention of investigators was attracted to use for this purpose in newborns the noninvasive, informative and portable method near-infrared spectroscopy (NIRS). Cerebral oxymetry successfully used for estimation brain circulation of the blood and blood volume in the brain vessels with combination constant monitoring blood pressure. This review outlines the basic principles, advantages NIRS technology in clinical studies brain oxygenation in healthy full term and premature newborns and also after asphyxia, vacuum extraction and cesarean section. Monitoring brain oxygenation in newborns which received cooling after heavy asphyxia permits during first 10 hours after birth to prognosis unfavorable outcome or fix the further strategy of treatment cerebral ischemia. Presented clinical use this method for treatment premature newborns with respiratory distress and circulatory insufficiency. It may help to determine the optimal target oxygen saturation. It is alsow useful monitoring during intensive therapy of extremely preterm neonates, due to the risk of impaired cerebral blood flow auto regulation in these patients. Indicated the perspectives of cerebral oxymetry in neonato logy for new diagnostic, treatment and prophylactic perinatal CNS damage.
