The Eight Immortals Dust explosion required "skin" urgently, and the Ministry of Health and Welfare spent more than 100 million yuan to urgently purchase "corpse skin" from abroad for emergency response. Doctors pointed out that during the debridement and skin grafting process, cadaver skin is better than synthetic skin dressings, and it is better preserved at low temperature. The main reason is that low-temperature corpse skin has good water retention, which can reduce the risk of bacterial infection. The only disadvantage is that it is scarce and difficult to obtain. Chief physician Dai Nianzi (right in the picture) emphasized that corpse skin (left in the picture) is mainly a dressing and has the richest biological activity in cryogenic preservation (Photo/Provided by the Tri-Service General Hospital)

Dai Nianzi, director of the Plastic Surgery and Burn Center of the Third General Hospital, pointed out , the skin is the largest organ in the human body, accounting for about 15% of the total body weight. It mainly wraps the surface of the body, separates the external environment of the human body, protects the internal tissues and organs of the body, and avoids mechanical damage and moisture. Loss of body fluids and invasion of microbial germs.

For burns and scalds, it is better to apply corpse skin

Especially when the human body encounters serious injuries, such as large-scale burns, causing skin If the defect is damaged, the protective function will be lost. The necrotic tissue must be debrided and removed as soon as possible, and the wound must be properly covered and protected. Even though many artificial dressings have been developed, the use of donor skin is still the most ideal biological dressing.

However, it should be noted that using cadaver skin is not a skin transplant. The cadaver skin is mainly used as a dressing to assist in the autologous production of skin. At present, skin dressings for burns and scalds can be divided into three categories: corpse skin, biological substitutes (pig skin), and artificial skin (artificial skin). In the acute stage of injury, the protective effects of the three are similar, but after 3 weeks, the testicles At this time, good or bad is judged as high or low.
