Umbilical cord stump medication with a topical dermo protective powder compared to dry care in healthy full-term and near-term newborns: a two-center prospective cohort study.

Background: Proper umbilical cord stump care during the first days of life (both in hospital and at home) should not be overlooked to prevent possible complications (e.g., purulent discharge, granulomas, or periumbilical erythema or omphalitis). Despite the known benefits of its correct execution, the care of umbilical cord stump remains controversial, and many different approaches are described. The World Health Organization suggests the use of dry cord stump care (easy and economic technique) in developed countries, but in many cases in the real life various topical antiseptics are used in combination with dry cord stump. The extracts of Arnica Montana (AM) have been reported to possess antibacterial, anti-inflammatory, antifungal, and immunomodulatory activities, very useful in the management of cord stump in full term infants.

Methods: In our study we evaluated the efficacy of a powder containing AM (study group- GrA) versus dry cord stump (control group-GrB) in a population of healthy newborn >35 weeks of gestational age (GA).

Results: Three hundred twenty-six neonates (mean GA 39±1 in both groups and body weight 3200 g and 3400±448 g respectively in GrA and GrB) were enrolled in two standard neonatal care units (163 neonates in GrA and 163 in GrB). At T1 (48 hours after discharge) GrA showed significantly reduced incidence of mild complications in toto, in particular a lower rate of wet umbilical cord stump). No differences between the two groups at T2 (1 week after discharge).

Conclusions: The use of a natural topical dermo-protective powder containing AM reduces the risk of minor complications, both nurse and parental workload in the first days after discharge, but does not have an impact on cord detachment and other complications in neonates >35 weeks GA.
