Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Kangaroo mother care (KMC) or skin-to-skin care (SSC) is a routine method of care in preterm neonates in neonatal intensive care units around the world. SSC is mostly defined as the skin-to-skin contact of the infant with the mother's or father's chest, which has been proven to reduce mortality, decrease severe illness, nosocomial infections and the length of hospital stay as well as to improve growth, breastfeeding and mother-child-relationship. During the last years several studies were performed showing that SSC provides comparable neonatal physiological stability compared to routine incubator care.
Near-infrared spectroscopy (NIRS) enables non-invasive, continuous monitoring of oxygenation and perfusion in different tissues. Several studies have shown that SSC has no negative influence on cerebral oxygenation saturation and physiological parameters compared to routine incubator care in preterm infants with respiratory support after the 5th day after birth. Nevertheless, until now there is no information on cerebral oxygenation and physiological parameters during SSC compared to routine incubator care in preterm neonates with respiratory support during the first 24 hours after birth, when transition still takes place and may cause unstable vital signs in neonates. Cerebral hypoxia as well as hyperoxia can cause severe brain damage due to perfusion disturbances, especially in ventilated preterm neonates.
Objectives
Primary aim: To assess, if the burden of cerebral hypoxia (calculated as the area under the curve outside the tissue oxygenation (cStO2) target range of 55% - 76%) in preterm neonates with respiratory support is different during SSC compared to routine incubator care on the first day after birth.
Secondary aims: To assess, if SSC has an influence on cFTOE (cerebral fractional tissue oxygen extraction) and routine monitoring parameters (arterial oxygen saturation \[SpO2\], heart rate \[HR\], respiratory rate \[RR\], mean arterial blood pressure \[MABP\], temperature) in preterm neonates with respiratory support compared to routine incubator care on the first day after birth.
Methods
Study population: Preterm neonates \<37+0 weeks of gestation with respiratory support admitted to the Division of Neonatology, Department of Paediatrics and Adolescent Medicine, Medical University of Graz after vaginal delivery or caesarean section will be eligible for the study.
Procedure: Patients and maternal medical history and main diagnoses, as well as routinely sampled laboratory results, provided therapy and respiratory support will be documented in each neonate.´
Measurements: For NIRS measurements the OxyPrem 1.4. (OxyPrem AG, Zurich, Switzerland) will be used. The NIRS measurements will take place once during the first day after birth before / during / after routine SSC and will last for 180 minutes.
After feeding the neonates will be brought in a prone position in the incubator and the NIRS sensor will be applied on the forehead for continuous cStO2 measurements throughout the study period. The neonate will rest in this position for 60 minutes. Afterwards the neonate will be brought on the mother's or father's chest (skin to skin) in a prone position and will stay in this position for 60 minutes. Finally the neonates will be brought back into the incubator for another 60 minutes in prone position. After 180 minutes the study period is over and the NIRS sensor will be removed.
Furthermore, NIRS will be combined with routine monitoring, such as pulse oxymetry (SpO2, HR), blood pressure measurements and measurements of temperature. Data will be stored in a polygraphic system (alpha-trace digitalMM, B.E.S.T. Medical Systems, Austria) for further analysis.

SSC
Incubator phase I: After feeding the neonates will be brought in a prone position in the incubator and the NIRS sensor will be applied on the forehead for continuous cStO2 measurements throughout the study period. The neonate will rest in this position for 60 minutes.
SSC phase: The neonate will be brought on the mother's or father's chest (skin to skin) in a prone position and will stay in this position for 60 minutes.
Incubator phase II: The neonates will be brought back into the incubator for another 60 minutes in prone position. After 180 minutes the study period is over and the NIRS sensor will be removed.
