Introduction

For small blisters, it is generally not necessary to puncture them. The blister fluid in small blisters is usually absorbed spontaneously, and leaving the blister intact helps maintain skin integrity, which is beneficial for the healing of the burn wound. Puncturing the blister may worsen the local injury and, if not properly cared for, can easily lead to infection. Avoiding puncture effectively reduces the risk of infection.

Generally speaking, whether a burn blister should be punctured depends on its size. If the blister is small, it usually does not require puncturing. However, if the blister is large, the blister fluid is difficult to absorb on its own, and the blister typically needs to be punctured using a sterile needle. Detailed explanations are as follows:

If the blister is small, it generally does not require puncturing. This is because the fluid within small blisters can usually be absorbed naturally. Avoiding puncturing helps preserve the integrity of the skin, which benefits the healing of the burn wound. Breaking the skin may worsen the local injury, and improper care can easily lead to infection. Not puncturing the blister can effectively reduce the risk of infection.

If the blister is large, the affected area usually presents with significant swelling and pain, and the blister fluid is difficult to absorb spontaneously. In such cases, the blister should be punctured using a sterile needle or aspirated with a syringe to prevent the wound area from expanding. Prior to puncturing the blister, strict disinfection of the local skin should be performed to prevent infection. After puncturing, the blister skin should be completely preserved to protect the wound and promote healing.

At the wound site, topical medications such as moisturizing burn ointment, Jingwanhong ointment, or mupirocin ointment may be applied under a doctor's guidance. These medications have effects such as clearing heat and detoxifying, removing decayed tissue and promoting granulation. Additionally, it is important to maintain cleanliness and dryness of the wound in daily care, avoiding scratching, rubbing, or other irritating behaviors. Adequate rest and dietary regulation are also important. Consuming nutrient-rich foods can promote wound healing.

What should I do if a child's hand is burned and blisters?

Burn blisters on the hand occur because the burn damages skin tissue, increases capillary permeability, and causes exudation and accumulation of tissue fluid under the epidermis to form blisters. Managing a child's hand burn with blisters involves local cooling, cleaning the wound, disinfection, applying ointment, and dressing the wound. After a child's hand is burned, they should immediately move away from the heat source to avoid further heating of the burned area.

How to treat burns with blisters to heal quickly

Burn blisters can be managed through methods such as rinsing with cool water, disinfection, blister management, topical medications, and oral medications. Disinfection helps eliminate bacteria at the burn site and reduces the risk of infection. After cleaning the burned area, use mild disinfectants such as povidone-iodine to disinfect the blistered area and prevent infection. Tight clothing that puts pressure on the blisters should be avoided.

How to treat a burn blister to heal quickly

Generally speaking, there is no such saying as "how to treat a burn blister quickly." For burn blisters, treatments may include rinsing with cool water to reduce temperature, removing clothing from the affected area, washing the wound, applying medication, and dressing the wound. During the healing process, avoid touching the burned area with your hands to prevent infection. Keep the burned area clean and dry, and avoid contact with water.

Why do burns cause blisters?

Burn blisters may be caused by mechanisms such as the skin's self-protective response, thermal injury with fluid accumulation, increased skin tension, post-burn infection, or damaged nerve endings. When the skin suffers from high-temperature injury, the body initiates a protective mechanism by forming blisters to isolate the heat source. It is important to keep the wound clean and avoid rupturing the blisters to prevent infection.
