Feasibility, Acceptability and Effects of Virtual Reality Distraction for Management of Stress in Mothers Expressing Their Maternal Milk (VR-MOM)

In neonatal intensive care units (NICUs), mothers are encouraged to express their milk using an electric breast pump. The milk is then fed to the premature newborns by a feeding tube until they are stable and mature enough to feed at the breast or by bottle. This practice is promoted by nurses and neonatologists due to its beneficial outcomes for newborns. Compared to newborns exclusively fed commercial infant formula, preterm newborns fed breast milk (BM) are less likely to suffer from necrotizing enterocolitis and late-onset sepsis. In addition, preterm births are often associated with multiple stressors (C-section, separation from the newborn). However, the discomfort associated with using an electrical pump may discourage its use (noise, uncomfortable sensations in the breasts). Overall, almost all mothers start expressing their BM after a premature birth but many stop after a few weeks due to fatigue and stress.

Current recommendations for mothers expressing BM in the NICU include regular skin-to-skin contact as well as being at the bedside or looking at the newborn's photo. Although these methods are effective in increasing BM production, they are not used by all mothers in the NICU. It appears that these strategies remind mothers of being separated from their newborn. Using distraction strategies when expressing BM could be a coping mechanism for such feelings.Few distraction interventions aimed at reducing maternal stress during breast milk expression have been identified in the literature. Some studies have examined the effect of music during milk expression in mothers of newborns hospitalized in the NICU. Researchers observed BM volume increase, nutritional value improvement and maternal cortisol level decrease. Furthermore, interventions focused on relaxation techniques for breastfeeding mothers have shown an increase in milk volume and a weight gain in newborns. Therefore, virtual reality (VR), an immersive experience (auditory and visually) seems to be an interesting option as it would provide a relaxing environment and distract mothers of newborns in NICU from the stress and discomfort experienced in order to promote breast milk expression.

Aim

The aim of this within-subject, pilot clinical trial is to assess the feasibility, acceptability, and preliminary effects of VR on stress, discomfort, and volume of expressed milk in mothers of preterm newborns.
