“…However, animal studies show that once blood flow is established, the pruning and growth ends [33]. The transition to extrauterine circulation involves increasing oxygen saturation to nearly normal levels and establishing an 8- to 10-fold increase in pulmonary blood flow [34, 35]. Altered pulmonary artery thickness and stiffness have been reported in prematurely born children, indicating that vascular impairment is part of the BPD pathology [36, 37].…”

Background Pulmonary hypertension (PAH) among children and adults has been linked to premature birth, even after adjustments for known risk factors such as congenital heart disease and chronic lung disease. The aim of this population-based registry study was to assess the risk of PAH following exposure to premature birth and other factors in the decades when modern neonatal care was introduced and survival rates increased. Methods Data on pulmonary hypertension and perinatal factors were retrieved from population-based governmental and national quality registers. Cases were adults and children over five years of age with pulmonary hypertension born from 1973 to 2010 and individually matched to six controls by birth year and delivery hospital. Conditional multiple logistic regression was performed to assess the risk of pulmonary hypertension following premature birth and to adjust for known confounding factors for the total study population and for time of birth, grouped into five-year intervals. Results In total, 128 cases and 768 controls were included in the study group. Preterm birth was over three times more common among cases (21%) than among controls (6%). The overall adjusted risk of pulmonary hypertension was associated with premature birth, OR = 4.48 (95% CI; 2.10–9.53). Maternal hypertension, several neonatal risk factors and female gender were independently associated with PAH when potential confounders were taken into account. For each five-year period, the risk of PAH following premature birth increased several times for children born in the 2000s and later, OR = 17.08 (95% CI 5.60–52.14). Conclusions Preterm birth, along with other factors, significantly contributes to PAH. PAH following premature birth has increased over the last few decades. Our study indicates that new, yet unknown factors may play a role in the risk of preterm-born infants developing PAH later in life.

Monitoring vitálních funkcí je nezbytnou a důležitou součástí péče o novorozence na všech typech oddělení neonatologie. Mezi základní sledované parametry patří srdeční akce, dechová frekvence a saturace hemoglobinu kyslíkem. Monitorovací metody se dělí na invazivní a neinvazivní, ty dále na bezdotykové a v praxi více rozšířené dotykové metody. Přehledový článek představuje standardní i méně standardní metody neinvazivního měření vitálních funkcí u novorozenců. V závěru článku autoři prezentují experimentální systém zahrnující senzorickou podložku se zabudovaným optickým vláknem pro snímání srdeční a dechové frekvence novorozence, vyvíjenou ve spolupráci s vědci Technické univerzity v Ostravě. Klíčová slova: neinvazivní monitoring, vitální funkce, neonatologie summary burčková H, Wiedermannová H, Čubík J, Kepák s, Pavlíček J. noninvasive monitoring of vital signs of the newbornMonitoring of vital signs is an essential and important part of the care for newborns in all types of neonatology departments. The basic monitored parameters include heart rate, respiratory rate, and peripheral blood oxygen saturation. Monitoring methods can be classified to invasive and non-invasive, the latter further into contactless and (more widespread in practice) contact methods. The review article presents standard as well as less common standard methods of non-invasive measurement of neonatal vital signs. At the end of the article, the authors present an experimental system including a sensory pad with a built-in optical fiber for sensing the heart and respiratory rate of a newborn developed in cooperation with scientists of the Technical University of Ostrava.

Background: The delivery room oxygen saturation (SpO2) monitoring in neonates is based on studies in term infants. Study of preductal-postductal SpO2 gradient in healthy preterms immediately after birth will help in follow-up of an abnormal gradient, rationalizing oxygen therapy, and early identification of congenital cyanotic heart disease. Aims and Objectives: SpO2 is initially low and gradually increases to normal in healthy term newborns postnatally. Postductal SpO2 is lower than preductal, but their difference gradually decreases postnatally. Our study aims to find out the preductal-postductal SpO2 gradient in healthy preterms and the correlation between gestational age and SpO2. In preterms, gradient may persist longer due to patent ductus arteriosus and higher pulmonary vascular resistance. Materials and Methods: This observational cross-sectional study has been conducted over 1 year with 80 preterms immediately after birth, after the Institutional Ethics Committee approval and parental informed consent. Preductal and postductal SpO2 were recorded by probes on right hand and left foot respectively for 20 min after birth. Data were analyzed by SPSS software. Results: This study shows that preductal-postductal SpO2 gradient is significant in the first 20 min of life in preterms, and there is significant positive correlation of gestational age with preductal SpO2 at 1 min and negative correlation of gestational age with time taken to achieve 90% SpO2. Conclusion: This study concludes that significant preductal-postductal SpO2 gradient persists for first 20 min of life in preterms and preductal SpO2 at 1 min decreases and time taken to reach SpO2 90% increases significantly with decreasing gestational age.
