Skin-to-Skin Care is Associated with Reduced Stress, Anxiety, and Salivary Cortisol and Improved Attachment for Mothers of Infants With Critical Congenital Heart Disease.

Objective: To estimate the effect of skin-to-skin care (SSC) on biobehavioral measures of stress (anxiety and salivary cortisol) and attachment (attachment scores and salivary oxytocin) of mothers before and after their infants' neonatal cardiac surgery.

Design: A prospective interventional, baseline response-paired pilot study.

Setting: Cardiac center of a large, metropolitan, freestanding children's hospital.

Participants: Thirty women whose infants were hospitalized for neonatal cardiac surgery.

Methods: Participants acted as their own controls before, during, and after SSC at two time points: once before and once after surgery. We measured the stress response of mothers, as indicated by self-reported scores of anxiety and maternal salivary cortisol, and maternal-infant attachment, as indicated by self-reported scores and maternal salivary oxytocin.

Results: Significant reductions in self-reported scores of anxiety and salivary cortisol were found as a result of SSC at each time point, as well as increased self-reported attachment. No significant differences were found in oxytocin.

Conclusion: Our findings provide initial evidence of the benefits of SSC as a nurse-led intervention to support maternal attachment and reduce physiologic and psychological stress responses in mothers of infants with critical congenital heart disease before and after neonatal cardiac surgery.
