Umbilical cord medication in healthy full-term newborns: a before-after uncontrolled quality improvement study

Umbilical cord care can be a stressful practice for parents. Complications of cord care can increase neonatal morbidity and mortality. The extracts of Arnica montana (AM) have been reported to possess antibacterial, anti-inflammatory, antifungal, and immunomodulatory activities. We aim to demonstrate the efficacy of AM on cord detachment and parents' stress level induced by cord medication in healthy full-term newborns. We enrolled full-term infants with a birth weight >= 2500 g in healthy conditions. Cord stumps of infants in the PRE-group were cleaned and dried, while cord stumps of infants in the POST-group were cleaned, dried, and medicated with a natural topic dermo-protective powder containing AM. After discharge, we interviewed parents on the stump status during follow-up visits in a pediatric office at 7 and 14 days of life, or by phone calls after follow-up visits. Long-rank test showed that time of cord separation of newborns in the PRE-group was significantly higher compared to that in the POST-group (p < 0.001). Parents of newborns in the PRE-group were significantly more stressed during cord medication compared to parents in the POST-group (2.0 (1.2 to 2.1) vs 1.0 (0.8 to 1.3), p = 0.011). Multivariate analysis showed a significantly linear relation with group assignment for cord separation (p < 0.001) and parents' stress during the medication (p = 0.033). Conclusion: The use of a natural topic dermo-protective powder containing AM reduces the time of cord separation, improves parents' stress level, and reduces the risk of complications.
