Management of friction blisters includes sterile drainage of the site while leaving the blister roof intact to serve as a dressing. This method helps relieve some discomfort and protects the site from superinfection. A donut of moleskin may also be applied to minimize additional trauma to the blister and to relieve discomfort. If the blister roof is already fully or partially removed, treat the site as an open wound with appropriate antiseptic and surgical bandage application. Hydrocolloid dressings have also been proven to decrease discomfort and encourage healing. Some recommend debridement of the skin of the blister, the use of a topical containing nitrofurazone, and the application of a bandage.[11]
Prompt attention to friction blisters is important to prevent the development of secondary impetigo with possible cellulitis and sepsis. Institute appropriate systemic antibiotic therapy if impetigo develops.
