AIM To find out whether a correlation of heart rate (HR) and respiratory frequency (RF) defined as HR-RF-ratio (HRR) may be helpful to identify arousals in term and preterm infants. METHODS Polygraphic recordings were performed in 25 term infants (gestational age 40.1 +/- 1.1 weeks) and 25 preterm infants (gestational age 31.1 +/- 1.3 weeks) during… (More)
The present study is an analysis of changes in cerebral oxygenation and cerebral blood volume (CBV) during periodic breathing in healthy term infants by means of near infrared spectroscopy (NIRS). Polygraphy included electrocardiogram, electrooculogram, heart rate, oxygen saturation, side stream capnography, two respiratory effort sensors, a movement… (More)
Cyclical fluctuations in cerebral blood flow velocity in Doppler measurements are a well known phenomenon. In 1992 Livera et al have shown in one patient, that cyclical fluctuations of cerebral blood volume could be measured with near infrared spectroscopy (NIRS). The aim of the present study was a quantification of the amplitude of cyclical fluctuations of… (More)
In order to measure the intracranial pressure (ICP) of 8 newborn with posthemorrhagic hydrocephalus (group A) we used the noninvasive technique via the anterior fontanel (Ladd monitor). The ICP was monitored in two different head positions (30 degrees elevated, horizontal). The median measurements were: elevated head position, 13 mm Hg, horizontal head… (More)
Preterm infants are highly susceptible to injuries following necessary and often life-saving medical interventions. Esophageal perforation is a rare, yet serious complication that can be caused by aerodigestive tract suction, endotracheal intubation, or nasogastric tube placement. We present the case of a neonate born at 23 weeks plus three days of… (More)
BACKGROUND As it has been reported that bladder voiding in sleeping full-term infants is consistently accompanied by a cortical arousal, it was the aim of the present study to find out whether this could also hold true for preterm infants. METHODS Polygraphic recordings were performed in 21 healthy preterm infants (10 female). The infants' gestational age… (More)
A computerized, PC-based system is introduced for sleep monitoring in infants. The system is capable of digitizing and storing 22 physiological variables over a whole-night sleep period. The preprocessed data can be displayed on a single page; further processing can be done on the digitally stored data.
