Which practice is recommended for blisters on burns: leave intact and apply dry dressings.

• A. Leave blisters intact and apply dry dressings
• B. Puncture blisters and apply wet dressings
• C. Remove blisters and cover with ointment
• D. Drain blisters and apply occlusive wrap

Answer: (A)

When a burn forms a blister, the blister acts as a natural protective barrier that cushions underlying tissue and helps keep bacteria out. Keeping the blister intact preserves that protection and reduces pain, whereas puncturing, removing, or draining the blister creates an open wound that is easier for bacteria to invade and heals more slowly. Applying a dry dressing over the intact blister protects it from friction and contamination without introducing excess moisture; wet or occlusive dressings can macerate the surrounding skin and promote infection. Therefore, the best approach in the field is to leave the blister intact and cover it with a sterile dry dressing to support healing and reduce infection risk. Seek medical care if the blister is large, shows signs of infection, or the burn is extensive.
