Why is silver-containing gel applied to the umbilical stump of a newborn?

Why Silver Gel is Applied to the Umbilical Stump of Newborns

Silver-containing gel should NOT be routinely applied to the umbilical cord of newborns in hospital or high-resource settings, as the American Academy of Pediatrics strongly recommends dry cord care alone, with no proven benefit from any topical antiseptic including silver products. 1, 2

Evidence-Based Rationale Against Silver Application

The 2016 AAP guidelines provide a strong recommendation (based on multiple randomized trials) that dry cord care—simply cleaning the umbilical stump with sterile water at each diaper change and keeping it dry and exposed to air—is the standard of care in high-resource hospital settings. 2

Why Silver and Other Antiseptics Are Not Recommended

• No reduction in infection rates: In hospital settings, all topical antiseptics (including alcohol, iodine, chlorhexidine, and silver-based products) do not reduce omphalitis or sepsis rates compared with dry cord care. 1, 2

• May delay healing: Topical antimicrobial agents can delay wound healing and cord separation. 2

• Risk of antimicrobial resistance: Application of topical antimicrobial agents may select for resistant and more pathogenic organisms over time. 2

• Omphalitis remains rare with dry care: The incidence of omphalitis in high-resource countries is approximately 1 per 1,000 infants managed with dry cord care, making routine antiseptic use unnecessary. 1, 2

When Antiseptic Gel IS Indicated (Context-Specific)

The only evidence-based exception is in low-resource settings with high neonatal mortality:

• Chlorhexidine (not silver) in high-mortality settings: The WHO recommends 4% chlorhexidine solution or gel for infants born at home or in settings with high neonatal mortality (not silver products). 1

• Proven mortality benefit: Three large studies (>44,000 subjects) in South Asian community settings demonstrated that chlorhexidine application within 24 hours of birth reduces both omphalitis (RR: 0.48; 95% CI: 0.40–0.57) and neonatal mortality (RR: 0.81; 95% CI: 0.71–0.92). 1

• Not applicable to hospitals: Even in low-income communities, infants born in hospitals should receive dry cord care, as the mortality benefit was demonstrated only in home birth settings. 1

Historical Context of Silver Use

Silver nitrate and silver-containing products have been used historically for umbilical cord care, but this practice predates modern evidence:

• Silver nitrate is caustic: FDA labeling warns that silver nitrate is caustic and irritating to skin and mucous membranes, and is highly toxic if ingested. 3

• Limited pediatric safety data: A 2025 systematic review found that while silver dressings are used for complex wounds and burns in infants, their use should be reserved for wounds at high risk of infection, with careful consideration of wound area and treatment duration due to potential systemic silver absorption. 4

• Outdated practice: A 1999 French survey found silver nitrate was rarely used (only once among 50 maternity units), reflecting the shift away from this agent. 5

Common Pitfalls to Avoid

• Do not apply traditional substances: Ash, herbal poultices, or human milk can introduce pathogenic bacteria including Clostridium tetani. 1, 2

• Do not use alcohol or iodine: These agents are not recommended and may delay healing. 2

• Do not dismiss infection signs: While rare, omphalitis can progress to necrotizing fasciitis with case-fatality rates up to 13%. 1, 2

When to Recognize and Treat Omphalitis

If infection develops despite proper dry cord care, recognize the four grades of severity:

1. Funisitis/discharge: Purulent, malodorous discharge alone. 2
2. Cellulitis: Periumbilical erythema and tenderness with discharge. 2
3. Systemic infection: Fever, lethargy, poor feeding. 2
4. Necrotizing fasciitis: Umbilical necrosis, ecchymosis, crepitus, bullae. 2

• Immediate workup: Obtain blood cultures, complete blood count, and C-reactive protein for any grade of omphalitis. 2

• Broad-spectrum antibiotics: Start empiric coverage for Staphylococcus aureus, Group A and B Streptococci, and Gram-negative organisms (E. coli, Klebsiella, Pseudomonas). 1, 2

Bottom Line

Silver gel application to the newborn umbilical stump is not evidence-based in modern hospital practice and should be replaced with simple dry cord care. The practice likely persists in some settings due to historical tradition rather than current evidence, but the AAP's strong recommendation against all topical antiseptics—including silver products—in high-resource settings is unequivocal. 1, 2
