Subclinical EVA Suit Contact Dermatitis
Earth designation: Subclinical Pressure Suit Dermatitis
Subclinical presentation of Pressure Suit Dermatitis in lunar residents. Contact dermatitis from prolonged pressure suit wear. The materials, pressure, heat, and sweat within EVA suits create ideal conditions for skin breakdown. Extended EVA operations are particularly problematic.
Lunar Risk Factors
Duration of EVA. Individual skin sensitivity. Pre-existing skin conditions. Suit fit issues. Inadequate suit hygiene between EVA operations. High-sweat activities in suit.
Symptoms
Erythema, itching, vesicle formation, skin breakdown at pressure points. Fungal superinfection in moist areas.
Diagnosis
Clinical examination of pressure points after EVA. Culture if secondary infection suspected.
Treatment
Barrier creams, topical steroids, EVA reduction, antifungals if secondary infection.
Lunar Medical Bay Protocol
Apply barrier cream (zinc oxide or petroleum jelly) to pressure points before EVA. Hydrocortisone 1% for inflammation. Clotrimazole cream for fungal superinfection. Review suit fit. EVA rest period if severe. Document and report to suit maintenance team.
Evacuation Criteria
Rarely requires evacuation. Secondary infection causing systemic sepsis.
Prevention
Pre-EVA barrier cream application. Suit fit optimization. Regular suit hygiene. Post-EVA skin inspection protocol.
