Clinical Trial Summary

The management of pain related to venipuncture remains insufficient in very preterm infants (VPI. The separation between the mother (father) and her(his) child can aggravate the short-term painful experience of the newborn. Accurate diagnosis and treatment of pain is necessary to preserve the well-being and brain development of VPI. A better understanding of the development of pain pathways and the cortical integration of nociceptive messages is essential to reach this goal.

Intervention

Behavioral:
Maternal vocal contact
Two consecutive venipuncture (order randomly balanced) within a short period of time will be realized with and without the presence of the mother talking/singing to her VPI infant. In this intervention group, the mother will be supported to talk or to sing to her infants during before and during the venipuncture.

Outcome

Type Measure Description Time frame Safety issue
Primary The cortical hemodynamic response profile The measurements will be performed using receiver and transmitter optodes to measure the variations of oxy and deoxyhemoglobin in the cerebral cortex below the optodes. The optodes will be placed in the primary and secondary somatosensory areas, and in other cortical areas (nociceptive pathway and control areas) using the EEG 10-20 classification. The data set will be collected over a basal period, a stimulation period and a post-stimulation period. Response patterns will be analyzed by mixed models and compared in VPIs in the different APM groups and with term neonates. A typical response associates an increase in oxyhemoglobin (Hb02) with a concomitant stability or decrease in deoxyhemoglobin (HHb). During a venipuncture (needed for the standard care of the infants) and realized around 30 (+/- 2) weeks PMAs in VPI
