Practical Steps for Applying Wet Wraps in Children with Atopic Dermatitis

Wet-wrap therapy with topical corticosteroids should be applied for 3-7 days (maximum 14 days in severe cases) as a short-term second-line treatment for moderate to very severe atopic dermatitis in children who have failed conventional topical therapy 1.

When to Use Wet Wraps

Use wet-wrap therapy in children with:

• Moderate to very severe atopic dermatitis unresponsive to standard topical treatments
• Acute erythrodermic dermatitis
• Therapy-resistant disease with intolerable pruritus
• Excoriated lesions from persistent scratching 1, 2

Consider wet wraps before escalating to systemic immunosuppressive therapies 1.

Step-by-Step Application Protocol

Preparation Phase

1. Give a lukewarm bath for 10-15 minutes to hydrate the skin 1
2. Pat skin dry gently (do not rub)
3. Apply topical corticosteroid to affected areas:
   • Use diluted steroids (1:10 dilution) for safety, particularly with medium-to-high potency corticosteroids 2, 3
   • Use low-to-medium potency TCS (e.g., fluticasone or mometasone) for children to minimize adrenal suppression risk 1
   • Apply low potency TCS on face, neck, and skin folds to avoid skin atrophy 1
   • Apply once or twice daily 1

Wet Wrap Application

1. Prepare damp cotton garments or bandages:

   • Soak cotton pajamas or tubular bandages in lukewarm water
   • Wring out excess water until damp (not dripping wet)
   • Optional: Warm damp garments briefly in dryer before application to improve child comfort and adherence 4

2. Apply the wet layer directly over the medicated skin

3. Apply a dry layer over the wet layer:

   • Use dry cotton pajamas or dry bandages
   • This creates an occlusive barrier that enhances medication penetration 1

4. Leave in place for several hours or overnight

5. Remove wraps when dry or after designated time period

Duration and Monitoring

• Standard duration: 3-7 days 1
• Maximum duration: 14 days in severe cases 1
• Do not use long-term due to risks of folliculitis, skin maceration, and secondary infections 5, 2

Critical Safety Precautions

Monitor for complications:

• Increased cutaneous infections (bacterial or viral)
• Folliculitis
• Skin maceration
• Signs of systemic corticosteroid absorption (particularly with prolonged use)

In adolescents: Use extreme caution and only short-term due to high risk of striae formation around puberty 2

Avoid wet wraps with topical calcineurin inhibitors - guidelines specifically recommend against this combination 5

Maintenance After Wet Wrap Therapy

Once acute flare is controlled:

• Transition to proactive therapy with twice-weekly application of low-to-medium potency TCS to previously affected areas 1
• Continue regular emollient use
• Consider rotating with emollient-only wraps for maintenance 2

Key Clinical Pearls

Advantages of wet wraps:

• Rapid response to therapy (often within days)
• Effective barrier against scratching
• Enhanced trans-epidermal penetration of medications 1
• Reduction in itch and sleep disturbance 2

Common pitfall: Underestimating the need for specialized training and patient/caregiver education. Success requires proper demonstration by trained nursing staff and clear written instructions 6, 2, 7.

Using clothing instead of bandages makes this intervention simpler, less time-intensive, and less expensive while maintaining efficacy 7.
