Detaljeret beskrivelse
Preterm birth rates are continuously increasing in almost all countries, with 15 million premature infants being born every year worldwide1. Despite rapid advances in technology, the number of preterm-born children who show short- and long-term sequelae of prematurity, even before reaching school age, remains high. Around 40% of low birth weight preterm infants experience a complex spectrum of unfavourable neurodevelopmental outcomes when compared with their pairs at term. Thus, prematurity is of great concern for health policies in both low- and high-income countries. The impaired development of preterm infants is not only associated with medical factors, but it is also at least partly a consequence of the atypical early-life environment of these infants, including exposure to pain and separation from the primary caregivers.
The aim of the present work was first, to assess whether early closeness with parents during essential but painful clinical procedures could have a positive role in pain modulation in preterm infants, thus contributing to the universal right to pain relief. Second, we aimed to investigate the possible role of the oxytocinergic system in this putative pain modulation through maternal vocal contact.
In the present protocol, we introduce the effects of separation and early pain exposure as two environmental factors that are even more deleterious when concomitant, inducing short- and long-term problems in the preterm infant's development. We then suggest that there are protective effects of early closeness between parents and preterm infants in early care and, more specifically, of early vocal contact between parents and preterm infants during hospitalisation. Lastly, we discuss the role of oxytocin (OXT) as a crucial biomarker for attachment processes and in relation to brain inflammation due to stressful procedures for preterm infants in the neonatal intensive care unit (NICU).

Eksperimentel: Maternal speech
During the intervention, mothers were asked to speak to their preterm infants in the incubators for 5 min preceding the heel prick procedure and for the subsequent 5 min.
|
In both intervention conditions, speaking and singing, the mothers were asked not to touch the baby but to pay close attention to his/her reactions and to modulate the voice accordingly.
A nurse was present during all procedures.

Aktiv komparator: Standard care
During the control condition (without the mother), the newborn was placed by the nurse in the incubator in the standard care conditions recommended for painful procedures (supine position, wrapped and contained by the nest).

pain score
Tidsramme: Immediately after the procedure
|
The PIPP-R score is a cluster of physiological and behavioural measures.
Physiological assessment was calculated on the heart rate and oxygen saturation levels as collected from the patient monitor by the researcher.
Inter-rater reliability was assessed by three independent coders: expert coders 1 and 2 performed blinded ratings from offline muted videos and digitally recorded physiological parameters, whereas coder 3 was a trained nurse and performed a direct online rating of the scores.
Higher levels of pain scores indicate higher levels of pain

oxytocin levels
Tidsramme: Pre procedure
|
Early relational experiences can persistently affect social behaviours by modifying the oxytocin system and endogenous oxytocin regulation is a potential protective mechanism for early pain perception.
Higher levels of oxytocin can indicate better pain protection.
