What are the implications of fluid leakage from second-degree (partial thickness) burns?

From the Guidelines

Second degree burns leaking fluid should be covered with a nonadherent bandage or clean cloth to protect the wound and reduce pain, and the patient should be evaluated by a healthcare professional, especially if the burn covers a large area or is on the face, hands, feet, genitals, or major joints. The leaking fluid is called serous exudate and is a normal part of the healing process. According to the 2024 American Heart Association and American Red Cross guidelines for first aid 1, burns involving the face, hands, feet, and genitals may require surgical intervention to prevent permanent disability.

When managing second degree burns, it is essential to clean the burn gently with mild soap and cool water, then apply an antibiotic ointment like bacitracin or polysporin (not neosporin, as it can cause allergic reactions) 1. The burn should be covered with a non-stick sterile dressing like Telfa and secured with gauze or medical tape, as recommended by the guidelines 1. The dressing should be changed daily or when it becomes wet or soiled.

For pain management, over-the-counter analgesics such as acetaminophen or NSAIDs are well tolerated and generally recommended for burn pain 1. A prospective study found no significant incidence of serious adverse events with the use of 800 mg IV ibuprofen every 6 hours 1. Therefore, patients can take over-the-counter pain relievers such as acetaminophen (Tylenol) 650mg every 6 hours or ibuprofen (Advil, Motrin) 400-600mg every 6 hours as needed for pain.

It is crucial to monitor the burn for signs of infection, such as increasing redness, swelling, warmth, pus, foul odor, fever, or if the burn doesn't show improvement within a week, and seek immediate medical attention if any of these symptoms occur. Burns heal by forming new skin cells at the edges and from deeper skin layers, and keeping the area clean and covered helps prevent infection while supporting this natural healing process.

From the FDA Drug Label

Reduction in bacterial growth after application of topical antibacterial agents has been reported to permit spontaneous healing of deep partial-thickness burns by preventing conversion of the partial thickness to full thickness by sepsis. The answer to the question about second degree burns leaking fluid is not directly addressed in the provided drug label. Key points:

• The label discusses the use of topical antibacterial agents, such as silver sulfadiazine, in preventing infection in burns.
• It mentions the potential for spontaneous healing of deep partial-thickness burns when bacterial growth is reduced.
• However, it does not provide information on the management of second degree burns that are leaking fluid. 2

From the Research

Second-Degree Burns Leaking Fluid

• Second-degree burns are known to be challenging to manage, and their treatment requires consideration of various factors such as burn site, patient age, and burn area 3.
• The leakage of fluid from second-degree burns can be a concern, as it may lead to infection and delayed healing.
• There is no unified standard or specification for the diagnosis, classification, surgical procedure, and infection diagnosis and grading of second-degree burn wounds, which poses great challenges to the formulation of clinical treatment plans 3.
• The use of dressings such as hydrocolloid dressings and silver sulfadiazine cream has been studied in the management of second-degree burns, with hydrocolloid dressings showing better wound healing, repigmentation, and less pain compared to silver sulfadiazine cream 4.
• Silver sulfadiazine has been shown to be an effective antibacterial agent for topical use in burns, with low toxicity and few side effects 5.
• However, the emergence of resistant Gram-negative bacilli, including Pseudomonas aeruginosa, is a concern, and the development of related metal sulfadiazines to be used against resistant bacteria is ongoing 5.
• A systematic review and meta-analysis found that new dressings with and without silver show better results than silver sulfadiazine for wound healing, and burns treated with dressings without silver are less likely to become infected than burns with silver sulfadiazine 6.
• Another study found that silver sulfadiazine therapy is effective for second- and third-degree burns, with positive outcomes such as enhanced healing, granulation tissue formation, and infection control 7.
