How to treat dark gray burn wounds?

The appearance of dark gray or black necrotic spots on the burn wound surface indicates that the tissue has been deeply damaged, usually involving the deep dermis or even the subcutaneous tissue. The formation of such necrotic spots is closely related to factors such as protein denaturation caused by thermal damage, microcirculatory disorders, inflammatory reactions, and secondary injuries.

Why do dark gray spots appear after a burn wound heals?

1. Protein denaturation: High temperatures cause tissue protein denaturation, cell structure destruction, enzyme system inactivation, and ultimately cell death. The dark gray or black appearance stems from a mixture of denatured hemoglobin and necrotic tissue.

2. Microcirculation disorder: Thermal damage directly destroys vascular endothelial cells, activates the coagulation system, leads to microthrombosis, further aggravates tissue ischemia and hypoxia, and promotes the expansion of necrosis.

3. Inflammatory response: After a burn, a large amount of inflammatory mediators are released, triggering an excessive inflammatory response, leading to tissue edema and aggravated microcirculatory disorders, forming a vicious cycle and aggravating tissue necrosis.

4. Secondary injury: Burn wounds are prone to secondary infection, bacterial toxins, and inflammatory reactions that further aggravate tissue damage. In addition, oxygen free radicals, proteases, etc. are also involved in the process of tissue necrosis.

How to treat this type of problem?

The appearance of dark gray necrotic spots on the burn wound usually indicates deep burns (such as deep II-degree or III-degree burns). Its treatment needs to be combined with modern medical methods such as debridement, anti-infection, and wound repair. Functional wound dressings (such as hydrocolloid dressings) can be used to protect the wound. Growth factors can be used to promote wound repair in the later stage.

Traditional Chinese medicine plays a certain auxiliary role in the treatment of burns, especially in promoting wound healing, reducing scar formation, and improving systemic symptoms. Traditional Chinese medicine believes that burns are caused by "fire poison" or "heat poison" invasion, which leads to blood stasis and skin malnutrition. The treatment principles are to clear away heat and detoxify, promote blood circulation and remove blood stasis, promote tissue regeneration, and heal sores. Traditional Chinese medicine treatment methods for dark gray necrotic spots on burn wounds include internal treatment and external treatment.

External treatment (Chinese medicine for external use)

Chinese medicine wet compress:

Use Chinese medicine decoction that clears away heat and toxic substances, activates blood circulation, and removes blood stasis to wet the wound.

Commonly used medicines: rhubarb, coptis root, phellodendron, lithospermum officinale, dandelion, angelica root, etc.

Method: Filter the decoction of Chinese medicine, wait for the liquid to cool, and apply it to the wound with gauze soaked in water, 1-2 times a day.

Chinese medicine ointment:

Apply Chinese medicine ointment with the effect of promoting tissue regeneration and healing sores to the wound surface.

Commonly used drugs: Lithospermum officinale oil, moist burn ointment (containing Coptis chinensis, Phellodendron chinense, Sanguisorba officinalis, etc.).

Method: After cleaning the wound surface, apply the ointment evenly and cover it with gauze.

Chinese medicine powder:

For wounds with less exudation, Chinese medicine powder can be applied externally.

Commonly used medicines: Shengji Yuhong ointment (containing frankincense, myrrh, dragon's blood, borneol, etc.).

The treatment of dark gray or black necrotic spots on burn wounds is a complex system engineering, which requires multidisciplinary collaboration and comprehensive use of various treatment methods to achieve the best therapeutic effect. Medical staff should continue to learn new knowledge and new technologies to provide better medical services for burn patients.
